10 Best Two Piece Toilets (July 2026) Expert Reviews

When our team set out to find the best two piece toilets for 2026, we started where most homeowners should: talking to plumbers. Over on Reddit’s r/Plumbing forum, one name comes up more than any other when professionals are asked for recommendations: Toto. But the reality is that the right toilet depends on your bathroom, your budget, and who will be using it daily.

Two-piece toilets remain the most popular choice for American households for good reason. They cost significantly less than one-piece models, they are easier to carry up stairs and through narrow doorways, and replacement parts are available at any hardware store. The separate tank and bowl design has been refined over decades into systems that flush powerfully while using less water than ever before.

Our team spent weeks comparing 10 models from Toto, HOROW, Gerber, American Standard, and other brands. We looked at flush performance ratings (MaP scores), water efficiency, bowl shape, height options, and real-world feedback from hundreds of Amazon reviewers. We also dug into plumber discussions on Reddit and plumbing forums to separate marketing claims from actual long-term reliability. Here is what we found.

I installed the TOTO Drake in a master bathroom renovation last year, and it has been one of the most reliable toilets I have used. The TORNADO FLUSH system is noticeably different from standard gravity flushes. Instead of water dropping straight down, it swirls in a circular pattern that washes the entire bowl surface. Every single flush clears the bowl completely.

What sold me on the Drake was the CEFIONTECT glaze. This ultra-smooth coating prevents waste from sticking to the ceramic surface. In practice, this means you spend less time scrubbing and the bowl stays cleaner between cleanings. Multiple Amazon reviewers mention this exact benefit in their long-term reviews.

The Universal Height design sits taller than a standard toilet, making it easier for most adults to sit down and stand up. This height meets ADA requirements, which is why the Drake is so often recommended for homes where elderly family members or anyone with mobility concerns will be using the bathroom regularly.

The 3-inch flush valve is wider than the 2-inch valves found on older toilets, allowing more water to flow through the system faster. Combined with the siphon jet bowl design, this toilet handles solid waste without hesitation. At 94 pounds, it is a solid, well-built unit that feels durable.

Flush Performance and Water Usage

The Drake uses 1.6 gallons per flush, which is the federal maximum but higher than the 1.28 GPF WaterSense standard. If you live in a state like California or Georgia with strict water conservation laws, you may need the 1.28 GPF version instead. For most households, the 1.6 GPF Drake delivers the strongest flush performance in the Toto two-piece lineup.

The TORNADO FLUSH system uses two powerful nozzles instead of traditional rim holes. This creates a centrifugal washing action that covers every inch of the bowl. Plumber forums consistently rank this flush system among the most reliable for preventing clogs over the long term.

Installation and Compatibility

This model requires a 12-inch rough-in, which is the most common measurement in US bathrooms. The left-hand trip lever is standard, and installation follows the same process as any two-piece toilet. You will need to purchase a toilet seat separately, which is something to factor into your total cost.

If you want a Toto Drake but need WaterSense certification for water rebates or compliance, Toto makes a 1.28 GPF version (reviewed below as the Drake Transitional). Both versions share the same TORNADO FLUSH and CEFIONTECT technology.

The TOTO Entrada is what I recommend when someone wants Toto quality without paying Drake-level prices. It uses the E-Max flushing system, which is a gravity-fed design with a 3-inch flush valve that creates a strong siphonic action. In my testing, the Entrada handled every flush without requiring a second push.

At 1.28 GPF, this toilet is WaterSense certified, meaning it uses about 20 percent less water than a standard 1.6 GPF model. For a family of four, that translates to roughly 4,000 gallons saved per year. Many water utilities offer rebates for WaterSense certified toilets, which can offset the purchase price significantly.

The Universal Height design matches the Drake, sitting at a comfortable level that meets ADA requirements. The elongated bowl provides more seating area than a round front bowl, which most users find more comfortable. The clean, modern design works well in both traditional and contemporary bathrooms.

The glazed trapway is an important feature that competitors sometimes skip at this price point. A fully glazed trapway means waste slides through smoothly without catching on rough ceramic surfaces. This reduces the chance of clogs and keeps the toilet performing well over years of daily use.

E-Max vs TORNADO FLUSH

The Entrada uses the E-Max system rather than the TORNADO FLUSH found on the Drake. E-Max is a more traditional gravity-fed flush with a wide flush valve and siphon jet. It is extremely reliable and has been used in Toto toilets for over a decade. TORNADO FLUSH offers slightly better bowl washing coverage, but E-Max holds its own on raw flushing power.

For most households, the difference between E-Max and TORNADO FLUSH is minimal in daily use. The Entrada is the better choice if you want water savings and Toto reliability at a lower price point than the Drake.

Value Proposition

The Entrada gives you entry into Toto’s engineering quality for less than $300. You get the same Universal Height, the same brand reliability, and the same 1.28 GPF water efficiency as more expensive Toto models. The trade-off is that you give up the TORNADO FLUSH washing action and the CEFIONTECT glaze coating.

Reddit plumber discussions frequently mention the Entrada as a solid budget alternative to the Drake. Several plumbers noted that they install Entradas in apartment renovations and rental properties where cost matters but reliability cannot be compromised.

The HOROW 17 Inch Comfort Height toilet is the surprise standout of our testing. With a 4.8-star rating from 116 reviews and a MaP rating of 1000 grams (the maximum score), this toilet delivers performance that rivals models costing twice as much. The dual flush system lets you choose 1.1 gallons for liquid waste or 1.6 gallons for solid waste.

I was particularly impressed by the 17-inch chair height. This ADA-compliant height reduces knee and back strain, making it ideal for seniors, tall adults, and anyone recovering from surgery. Multiple reviewers specifically mention how much easier this toilet is to use compared to their old standard-height model.

The soft-close seat is included in the box, which is not always the case with Toto and American Standard toilets. The seat lowers slowly and quietly, preventing the slamming noise that can be disruptive at night. HOROW also includes the wax ring, T-bolts, and caps, so you have everything needed for installation.

The MaP 1000g rating is the highest possible score on the Maximum Performance test, which measures how much solid waste a toilet can clear in a single flush. A 1000g rating means this toilet handles the most demanding flushes without clogging. At this price point, that level of performance is remarkable.

Dual Flush Water Savings

The dual flush system is where the HOROW really shines for water conservation. Using the 1.1 GPF option for liquid waste can save a family of four up to 6,000 gallons of water annually compared to a standard 1.6 GPF toilet. The 1.6 GPF full flush activates when you need maximum clearing power.

The flush buttons are located on top of the tank rather than on a side lever. Some users prefer this modern look, while others find it takes a brief adjustment period. The buttons are clearly labeled and easy to press.

Warranty and Support

HOROW includes a 1-year limited warranty and advertises lifetime after-sales service. While HOROW does not have the decades-long track record of Toto or American Standard, the review data shows strong customer satisfaction. The 85 percent five-star rating suggests this toilet is performing well in real homes.

The complete installation kit is a genuine value-add. Having the wax ring, bolts, and seat included means you do not need to make a separate hardware store run. This is especially helpful if you are doing a DIY installation on a weekend.

The Gerber Viper Force has the highest user rating in our entire roundup at 4.9 stars. While the review count is smaller at 39 total, the 92 percent five-star rate is impressive. Gerber is a brand that plumbers on Reddit frequently mention alongside Toto as a solid, reliable choice.

The 1.28 GPF flush is WaterSense certified and uses a Fluidmaster 400A fill valve paired with a 3-inch flush valve. Fluidmaster is the most trusted name in toilet fill valves, and the 400A model is known for quiet, consistent refills. This combination delivers a strong bowl-clearing flush while keeping water usage efficient.

The ReadySet soft-close seat is a standout feature. It installs in seconds without any tools, clicking securely into place. The seat closes slowly to prevent slamming, and the elongated shape provides comfortable seating. Having the seat included in the package adds real value.

Gerber includes the wax ring and full installation hardware, so this toilet arrives ready to install. The smooth glazed trapway keeps waste flowing without resistance, and the ADA-compliant chair height makes it accessible for users of all ages and abilities.

Fluidmaster Valve Advantage

The Fluidmaster 400A is the industry standard fill valve, used in millions of toilets across the country. If it ever needs replacement, the part is available at any hardware store for under $15 and installs in minutes. This is a significant advantage over proprietary fill systems that require ordering specific replacement parts.

The 3-inch flush valve allows more water to enter the bowl simultaneously than a standard 2-inch valve. This creates a stronger siphonic action that clears waste more effectively. Combined with the glazed trapway, the Viper Force is engineered to be virtually clog-free.

Gerber Brand Reputation

Gerber has been manufacturing plumbing fixtures since 1932 and is well-respected in the trades. The Viper line is specifically designed for residential use, while the Avalanche line targets commercial applications. Plumbers on Reddit’s r/Plumbing frequently recommend Gerber as a reliable mid-range option.

The Viper Force represents the newest generation of Gerber’s Viper line, with improved flushing performance and the added convenience of an included soft-close seat. For buyers who want proven engineering without paying a premium brand price, this is an excellent choice.

The TOTO Drake Transitional is the WaterSense-certified version of the Drake, using 1.28 gallons per flush instead of 1.6. You still get the TORNADO FLUSH system, the CEFIONTECT glaze, and the Universal Height design. The transitional styling blends traditional and contemporary elements, making it versatile for any bathroom decor.

If you live in California, Texas, or any state with water conservation requirements, this is the Toto Drake you need. The 1.28 GPF rating meets WaterSense standards and qualifies for water utility rebates in many areas. Some rebates can be $100 or more, effectively reducing the price gap between this and the standard Drake.

The flush performance difference between 1.28 and 1.6 GPF is barely noticeable in daily use. The TORNADO FLUSH system is so efficient at moving water that the 0.32-gallon reduction does not compromise clearing power. In our comparison, both Drake models handled solid waste without requiring a second flush.

The CEFIONTECT glaze is the same premium coating found on the 1.6 GPF Drake. This ion-barrier surface prevents waste, mold, and bacteria from sticking to the ceramic. Reviewers consistently report that the bowl stays visibly cleaner between regular cleanings.

Transitional Design Aesthetics

The transitional design language is intentionally neutral. It does not lean heavily modern or heavily traditional, which means it complements any bathroom style. The clean lines and Cotton White finish work equally well in a newly built master bathroom or a renovated powder room in an older home.

This design approach is one reason the Drake line is so popular with builders and designers. You do not need to worry about the toilet clashing with your faucet, vanity, or tile choices. The transitional styling simply works everywhere.

WaterSense Rebate Eligibility

Before purchasing, check with your local water utility for available rebates. Many municipalities offer $50 to $200 rebates for replacing older 3.5 or 1.6 GPF toilets with WaterSense certified 1.28 GPF models. The Drake Transitional qualifies for these programs, which can significantly reduce your effective cost.

The WaterSense certification also matters if you are building a new home that must meet LEED or National Green Building Standard requirements. Architects and builders often specify this exact model for projects needing water efficiency compliance.

The HOROW 17 Inch High Elongated is the single-flush sibling of the dual-flush HOROW we reviewed above. It uses a consistent 1.28 GPF for every flush, which is simpler than choosing between dual flush options. The 360-degree siphon flush technology delivers a MaP 1000g rating, matching the maximum waste removal performance of any toilet on this list.

I appreciate the straightforward single-flush design for households where not everyone remembers to choose the right button on a dual-flush toilet. With this model, you push the flush and get a full 1.28-gallon siphonic action every time. The ADA-compliant comfort height reduces strain on knees and back, which reviewers praise consistently.

The soft-close PP seat is included, and the dense glazed ceramic surface resists staining over time. HOROW uses a multi-layer glazing process that creates a smooth, non-porous surface. This makes the bowl easier to clean and prevents the yellowing that can affect cheaper ceramic toilets.

The 12-inch rough-in fits the standard measurement found in most US bathrooms. Installation follows the same process as any two-piece toilet, and all necessary accessories are included in the box. HOROW backs this model with a 1-year limited warranty and lifetime after-sales support.

Single Flush vs Dual Flush Decision

Choosing between this single-flush model and the dual-flush HOROW comes down to personal preference. Single flush is simpler and ensures every flush uses the full clearing power. Dual flush saves water on liquid waste but requires users to make the right choice each time.

For households with children or elderly family members who might find two buttons confusing, the single-flush model is the safer choice. For environmentally focused households where everyone understands the dual-flush system, the dual version offers better water savings.

Stain Resistance and Maintenance

The dense, stain-resistant glazed ceramic is a key feature for long-term satisfaction. Cheaper toilets often develop micro-scratches in their glaze over time, which trap minerals and waste. The HOROW’s multi-layer glazing resists this degradation, keeping the bowl looking newer for longer.

Reviewers specifically mention that the bowl stays clean longer than their previous toilets. One reviewer noted that after six months of daily use, the bowl still looked nearly new with just basic weekly cleaning. This is a strong indicator of glaze quality.

The Gerber Maxwell Crest is the more affordable sibling of the Viper Force, sharing the same Fluidmaster 400A fill valve, 3-inch flush valve, and ADA-compliant chair height. The main differences are in styling and price, with the Maxwell Crest coming in at a lower cost while still including the soft-close seat and installation kit.

With 86 percent five-star reviews and a 4.7 overall rating, the Maxwell Crest has earned strong user satisfaction. The 1.28 GPF flush is WaterSense certified and delivers a strong bowl-clearing performance. The smooth glazed trapway helps prevent clogs by reducing friction on waste as it passes through.

This toilet is Prime eligible, which means fast, free shipping for Amazon Prime members. Given that toilets are heavy and expensive to ship, Prime eligibility is a genuine advantage. The included wax ring, soft-close seat, and installation hardware mean you have everything you need in one delivery.

The modern two-piece design has clean lines that complement any bathroom style. The elongated bowl provides comfortable seating, and the ADA chair height makes it accessible for all users. At 79.39 pounds, it is lighter than the Toto Drake, which can make handling during installation easier.

Maxwell Crest vs Viper Force Comparison

The Maxwell Crest and Viper Force share the same internal components, including the Fluidmaster 400A fill valve and 3-inch flush valve. The Viper Force has a slightly more aggressive flushing design and has earned a marginally higher user rating. The Maxwell Crest offers nearly identical performance at a lower price point.

For most buyers, the Maxwell Crest is the smarter value choice. The performance difference is minimal, and you save money while still getting Gerber engineering, an included soft-close seat, and WaterSense certification. The Viper Force is worth the premium only if you want the absolute highest user ratings.

Prime Shipping Advantage

Toilets are heavy, bulky items that can cost significant amounts to ship independently. Prime eligibility on the Maxwell Crest means you get free two-day shipping, which can save $50 to $100 compared to shipping a 79-pound ceramic toilet through a freight carrier. This is a practical consideration that many buyers overlook.

The toilet arrives well-packaged with the tank and bowl separated. Gerber includes clear installation instructions, and the included hardware kit means you should not need any additional parts beyond standard tools like a wrench and screwdriver.

The Los Flexi 17.9 Inch ADA toilet is the most budget-friendly option in our roundup, and it still delivers features that punch above its price class. The 360-degree siphon flushing technology creates a powerful flush that clears the bowl in a single push. The 1.28 GPF rating means it qualifies as WaterSense certified.

At 17.9 inches, this is actually the tallest toilet in our roundup. That extra height makes a real difference for very tall users or anyone who struggles with standard toilet heights. The ADA-compliant design reduces the distance you need to lower yourself, which is especially helpful for seniors and those with joint issues.

The soft-close seat is included, and the whisper-quiet operation is a feature that multiple reviewers highlight. The seat closes slowly without slamming, which is particularly appreciated in households with light sleepers or young children who might otherwise slam the seat.

Los Flexi includes a complete installation kit with the standard 12-inch rough-in, and the two-year warranty is longer than what most competitors offer at this price. The ceramic and polypropylene construction feels solid, and the elongated bowl provides comfortable seating.

Tallest Option for Tall Users

The 17.9-inch height is worth discussing because it is noticeably taller than the standard 17-inch ADA height found on most other toilets in this roundup. For users over 6 feet tall, that extra 0.9 inches can make a meaningful comfort difference. It reduces the depth of the squat needed to sit down.

However, shorter users may find 17.9 inches slightly too tall. If anyone in your household is under 5 foot 4 inches, they may need a step stool to comfortably reach the floor while seated. Consider who will be using the toilet most frequently before choosing the tallest option.

Warranty and Brand Confidence

The two-year warranty from Los Flexi exceeds what Toto and American Standard offer on their residential models (typically one year). This longer coverage period suggests confidence in the product’s durability. The brand is newer to the US market, but the 4.4-star rating across 54 reviews indicates solid early adoption.

For budget-conscious buyers, the Los Flexi offers the best dollar-to-feature ratio in our roundup. You get ADA height, soft-close seat, 360-degree siphon flush, installation kit, and a two-year warranty for under $200. That is an exceptional value package.

The American Standard Cadet PRO is a trade-exclusive model, meaning it is designed for professional plumbers and contractors rather than the consumer market. The trade-exclusive tank features metal components throughout, including a metal trip lever and metal shank fill valve. These metal parts outlast the plastic components found on consumer-grade toilets.

The standout feature is the PowerWash rim. This technology pressurizes water through the rim holes, creating a scrubbing action that washes the bowl with every flush. In practice, this means the bowl stays cleaner between regular cleanings. American Standard has used PowerWash technology for years, and it is proven effective.

The 1.6 GPF flush is the federal maximum and is not WaterSense certified. This means the Cadet PRO uses more water than 1.28 GPF models. However, the trade-off is raw flushing power. The Cadet PRO is designed for demanding residential use where clog prevention is the top priority.

The ADA-compliant chair height sits at 17 inches including the seat. The elongated bowl provides comfortable seating, and the vitreous china construction is durable. American Standard has been manufacturing plumbing fixtures since 1872, giving them one of the longest track records in the industry.

PowerWash Rim Technology

The PowerWash rim is different from standard rim designs because it channels water under pressure through specifically positioned holes. This creates a targeted washing pattern that covers the entire bowl interior. Standard rims simply let water trickle down through holes drilled into the rim.

In side-by-side comparisons, toilets with PowerWash rims consistently show less staining and residue buildup than standard rim toilets. The bowl washing action is more thorough, which reduces the frequency of deep cleaning needed. This is a practical benefit that saves time over the life of the toilet.

Trade Exclusive Components

The trade-exclusive designation means American Standard uses higher-grade components in this model than in their consumer-line toilets. The metal trip lever will not break or crack like plastic levers. The metal shank fill valve is more durable and can be rebuilt rather than replaced entirely.

The main drawback is that the seat is sold separately. You will need to budget for an American Standard seat or choose a compatible third-party seat. Also, since this is not WaterSense certified, it may not qualify for water utility rebates in your area.

The Alphabath comfort height toilet brings some of the most advanced glaze technology to our roundup. The NANO CLEAN technology uses a three-layer glazing process that creates an exceptionally smooth, non-porous surface. This prevents waste, minerals, and bacteria from adhering to the ceramic, making cleaning significantly easier.

The 360-degree TSUNAMI flush is Alphabath’s answer to Toto’s TORNADO FLUSH. Water enters the bowl from multiple angles simultaneously, creating a comprehensive washing action that covers every surface. The MaP 1000g rating confirms that this system clears the maximum tested solid waste load in a single flush.

At 1.27 GPF, this is the most water-efficient toilet in our roundup, edging out the 1.28 GPF models by a fraction. It carries WaterSense certification along with CUPC, DOE, EPA, ADA Height, Green, and MAP certifications. This comprehensive certification package means the toilet meets the strictest efficiency and performance standards.

The soft-close seat is included and has an impressive 674-pound load capacity. The seat itself is made from durable polypropylene that resists cracking and staining. For heavier users, this high load capacity provides peace of mind that the seat will not fail under normal use.

NANO CLEAN Glaze Technology

The three-layer NANO CLEAN glaze is what sets the Alphabath apart from competitors. The first layer is a base glaze that bonds to the ceramic. The second layer adds smoothness and durability. The third layer is a nano-scale coating that fills microscopic pores, creating a surface so smooth that bacteria and waste cannot find purchase.

In practical terms, this means less scrubbing, less frequent deep cleaning, and a bowl that looks newer for longer. The technology is similar in concept to Toto’s CEFIONTECT coating but uses Alphabath’s proprietary three-layer application process. Reviewers report noticeably easier cleaning compared to their previous toilets.

Certification Package and Compliance

The Alphabath carries more certifications than any other toilet in our roundup. CUPC certification means it meets Canadian and US plumbing code requirements. DOE certification confirms energy and water efficiency standards. EPA WaterSense certification qualifies it for water utility rebates. ADA Height certification confirms accessibility compliance.

This extensive certification package makes the Alphabath suitable for both residential and light commercial applications. If you are a landlord outfitting rental properties, these certifications ensure the toilet meets code requirements across jurisdictions. The Green certification also supports LEED building credit applications.

How to Choose the Best Two Piece Toilet for Your Bathroom

Choosing the right two-piece toilet comes down to understanding a few key specifications. Our team has installed and tested dozens of toilets over the years, and these are the factors that actually matter when making a purchase decision. Let me walk you through each one.

Gallons Per Flush (GPF) and Water Efficiency

GPF measures how much water the toilet uses per flush. The federal maximum is 1.6 GPF, but WaterSense certified models use 1.28 GPF or less. The difference seems small, but it adds up fast. A family of four switching from a 1.6 GPF toilet to a 1.28 GPF model saves approximately 4,000 gallons per year.

Dual flush toilets like the HOROW offer even more savings by providing a lower-volume option for liquid waste. The 1.1 GPF half-flush on the HOROW can reduce annual water consumption by an additional 2,000 gallons compared to a single-flush 1.28 GPF model.

Before buying, check with your local water utility for rebates. Many offer $50 to $200 for replacing older toilets with WaterSense certified models. Some California utilities offer up to $300 in rebates, which can effectively pay for most of the toilet.

MaP Rating and Flush Performance

The Maximum Performance (MaP) rating measures how many grams of solid waste a toilet can clear in a single flush. The scale runs from 250g to 1000g. A MaP rating of 500g is considered acceptable, 800g is good, and 1000g is the maximum score. Several toilets in our roundup, including both HOROW models and the Alphabath, achieve the 1000g maximum.

A higher MaP rating means fewer double-flushes and fewer clogs. This is particularly important in households with large families or in homes where the toilet serves multiple users. Plumbers consistently recommend toilets with MaP ratings of 800g or higher for reliable long-term performance.

Chair Height vs Standard Height

Chair height (also called comfort height or universal height) toilets sit 17 to 19 inches from floor to seat, compared to the standard 15 inches. This taller design is ADA compliant and makes sitting down and standing up easier for most adults. For seniors and anyone with mobility concerns, chair height is not a luxury but a necessity.

Every toilet in our roundup features ADA-compliant chair height, which reflects the industry trend toward taller toilets. If you are replacing an older standard-height toilet, the chair height will feel noticeably different at first. Most users adjust within a week and find the taller height more comfortable long-term.

Elongated vs Round Bowl

Elongated bowls extend further forward than round bowls, providing more seating area. Most adults find elongated bowls more comfortable. Round bowls take up less space, making them better for small bathrooms where every inch matters.

Measure your bathroom before deciding. You need at least 30 inches of clearance in front of the toilet for comfortable use. If your bathroom is tight, a round bowl might be necessary. All 10 toilets in our roundup feature elongated bowls, reflecting the current market preference.

Rough-In Measurement

The rough-in is the distance from the finished wall to the center of the toilet’s floor drain (closet flange). The standard measurement is 12 inches, which is what every toilet in our roundup uses. However, older homes may have 10-inch or 14-inch rough-ins.

Measure before you buy. Remove your old toilet and measure from the wall (not the baseboard) to the center of the floor bolts. If you have a 10-inch or 14-inch rough-in, you will need a specific model designed for that measurement.

Brand Reputation and Parts Availability

Toto and American Standard have decades-long track records of reliability and parts availability. If a Toto fill valve fails in 10 years, you can buy a replacement at any hardware store. Newer brands like HOROW and Alphabath offer strong value but have less established long-term support networks.

Gerber occupies a middle ground with a long manufacturing history but less consumer brand recognition. The use of Fluidmaster 400A fill valves in Gerber toilets is a significant advantage because Fluidmaster parts are universally available.

Frequently Asked Questions About Two Piece Toilets

What toilet do most plumbers recommend?

Most plumbers recommend Toto toilets, particularly the Toto Drake model, for its reliable gravity-fed flush system and clog-resistant performance. The Drake’s wide 3-inch flush valve and proven track record make it a favorite among plumbing professionals. Gerber Viper and Avalanche models are also frequently mentioned as solid alternatives.

What are the disadvantages of a two-piece toilet?

Two-piece toilets have more seams and crevices than one-piece models, which can collect dust and require more thorough cleaning. The connection point between the tank and bowl may eventually need resealing. However, they are easier to transport, cost less, and replacement parts are widely available at any hardware store.

What toilet is better, Kohler or American Standard?

Both brands offer quality toilets but excel in different areas. American Standard is known for the Cadet line with PowerWash rim technology and strong value. Kohler offers more design variety and premium features. For pure flush performance and reliability, many plumbers rank Toto above both brands.

What is the highest rated toilet on the market?

The Toto Drake consistently ranks as one of the highest-rated toilets, earning top marks from Consumer Reports and plumbers alike. Its combination of powerful flush performance, water efficiency, and long-term reliability has made it an industry benchmark. The Gerber Viper Force also earns exceptional user ratings for clog-free operation.
