TOTO UltraMax II One-Piece Elongated Toilet
The TOTO UltraMax II combines sophisticated design with advanced performance. Its one-piece construction creates a smooth, seamless profile that is not only visually appealing but also much simpler to keep clean. The universal height offers a comfortable, chair-level seating position that is accessible for most adults.
At the core of its performance is the efficient 1.28 GPF Tornado Flush system, which uses two nozzles to create a powerful centrifugal rinsing action. This is enhanced by TOTO’s CEFIONTECT glaze, an extraordinarily smooth surface that prevents waste and particles from adhering to the ceramic. This model is also WASHLET+ ready, allowing for easy future upgrades, and includes a SS124 SoftClose seat for quiet, gentle closing.
Aqua-Magic V RV Toilet Hand Flush
The Aqua-Magic V is a high-profile RV toilet designed to provide the comfort and feel of a household toilet in a recreational vehicle. Its classic style is versatile enough to suit a wide range of RV interiors. The textured lid is a practical feature, as it sheds water and resists scuffs from travel and use.
Functionality is straightforward and effective with a single-handle flush system. Pressing the handle halfway adds water to the bowl, while pushing it all the way down initiates a complete flush with 100% bowl coverage. This design ensures efficient water use and reliable waste removal, which is essential for life on the road.
TOTO Aquia Wall-Hung Dual-Flush Toilet Bowl
The TOTO Aquia Wall-Hung toilet offers a distinctly modern and minimalist aesthetic for the bathroom. By mounting the tank within the wall, this model saves significant space and makes floor cleaning exceptionally easy. The universal height provides a comfortable and accessible seating position.
This toilet features a dual-max flushing system, allowing you to choose between a partial or full flush to conserve water. Its design is CalGreen compliant, meeting strict environmental standards. The wall-hung installation creates a floating effect that can make a small bathroom appear more spacious and is easier to maintain.
WOODBRIDGE T-0001 Dual Flush One Piece Toilet
The WOODBRIDGE T-0001 boasts a luxurious modern design with a clean, sleek look that complements various bathroom styles from traditional to contemporary. Its one-piece construction is not just about aesthetics; it is specifically engineered to be one of the easiest toilets to clean on the market.
This model features a fully concealed trap-way, which eliminates the hard-to-reach bends and corners that typically gather dust. The surface is completely smooth, with no large mounting holes or plastic caps to clean around. Despite its quiet operation, the siphon flushing system and fully glazed flush passage deliver a powerful and reliable flush that handles waste effectively.
TOTO SoftClose Slow Close Elongated Toilet Seat
This is not a toilet, but a high-quality accessory that can upgrade many existing toilets. The TOTO SoftClose seat is designed for use with elongated front bowls and is constructed from solid high-impact, high-gloss polypropylene for durability and a clean appearance.
The key feature is the slow-closing mechanism, which ensures the seat and lid lower gently and quietly every time. This eliminates the noise of a slamming seat and helps prevent damage to the seat itself and the toilet bowl over time. It is a simple upgrade that adds a touch of convenience and refinement to any bathroom.
Ultramax II 1.28 GPF Elongated 1 Piece Toilet
This Ultramax II model is an elongated one-piece toilet that offers a streamlined look for the bathroom. The one-piece design contributes to a cleaner silhouette and reduces the areas where dirt and bacteria can accumulate, simplifying your cleaning routine.
It operates with a water-efficient 1.28 gallons per flush. Please note that product information for this specific model is limited, and it cannot be shipped to California due to local water conservation regulations. It is advisable to confirm all specifications and compatibility before purchase.
Lysol Clean & Fresh Toilet Bowl Cleaner
This product is a maintenance essential rather than a toilet fixture. Lysol’s Clean & Fresh Toilet Bowl Cleaner in Ocean Fresh scent is formulated to keep your toilet hygienic and smelling pleasant. Its thick formula is designed to cling to the vertical surfaces of the bowl for better contact with stains.
It is effective at killing 99.9% of viruses and bacteria, helping to disinfect the toilet bowl with each cleaning. The Max Coverage™ design helps the product reach under the rim to tackle hidden grime, making it a reliable partner for maintaining any toilet, including the one-piece models featured in this list.
American Standard Compact Cadet 3 One-Piece Toilet
The American Standard Compact Cadet 3 is an excellent choice for bathrooms where space is at a premium. It combines an elongated bowl for added comfort with a compact tank design that projects less from the wall, saving valuable inches.
This model includes the EverClean surface, an antimicrobial finish that helps maintain cleanliness by inhibiting the growth of stain-causing bacteria, mold, and mildew on the porcelain. For added convenience and quiet operation, it comes with a slow-close seat and lid, preventing loud slams and potential damage.
KOHLER Veil One-Piece Intelligent Toilet
The KOHLER Veil represents the pinnacle of bathroom technology and design. This intelligent toilet is a streamlined one-piece unit that integrates a bidet directly into its design, eliminating the need for a separate seat attachment. Its compact, tankless profile offers a strikingly modern look.
It features Comfort Height seating for easier sitting and standing. The integrated bidet includes a stainless steel wand with a wide array of customizable functions, including adjustable spray shape, position, water pressure, and temperature, plus pulsate and oscillate modes. This all-in-one solution provides a spa-like experience with integrated personal cleansing.
TOTO Drake Two-Piece Elongated Toilet
Please note that the TOTO Drake is a two-piece toilet, which differs from the one-piece focus of this article. Two-piece toilets have a separate tank and bowl, which can sometimes be easier to install and transport but may have more crevices that require cleaning.
The Drake line from TOTO is well-regarded for its reliable performance and efficient flushing system. This particular model features an elongated bowl for added comfort and uses 1.6 gallons per flush. While it is a dependable fixture, its two-piece construction places it outside the specific category of seamless, easy-to-clean one-piece toilets highlighted in this roundup.
Buying Guide: How to Choose the Best One-Piece Toilet for Your Home
Choosing a new toilet can feel like a big decision. It’s a fixture you’ll use every day, and you want something that’s reliable, easy to clean, and looks good. I’ve found that one-piece toilets often check all these boxes, but you need to know what to look for before you buy. The seamless design isn’t just about looks; it means no nooks and crannies for grime to build up, which is a huge win for your cleaning routine.
First, consider the flushing system. You want power and efficiency. Look for a powerful flush that can clear the bowl in one go. Many modern toilets use a pressure-assisted mechanism, which uses air pressure to create a very strong flush, or a gravity-fed system with a fully glazed trapway for a smooth, clog-free performance. A good flush is non-negotiable, so pay attention to MaP (Maximum Performance) scores, which tell you how much solid waste the toilet can handle.
Next, think about height. Standard toilet heights are around 14-15 inches from the floor to the top of the bowl rim. This can be quite low for some people. A comfort height or chair height toilet, which is around 16-17 inches, is much easier to sit down on and stand up from. It’s a small change that makes a big difference in comfort, especially for taller individuals or anyone with mobility concerns.
Then there’s the bowl shape. You’ll typically choose between elongated and round front. An elongated bowl offers more seating space and is generally considered more comfortable for adults. A round front bowl saves space, making it a better fit for smaller or compact bathrooms. Be sure to measure your space carefully to ensure a good fit.
Finally, don’t forget about the little things. A slow-close seat is a fantastic feature that prevents loud slamming. Look for toilets with an everglide or similar mechanism. Also, check the warranty. A strong, long-term warranty from the manufacturer is a good sign of a quality product that’s built to last. By focusing on the flush, height, bowl shape, and these extra features, you can find one of the best one-piece toilets for your home that will serve you well for years.
Frequently Asked Questions
What is the main advantage of a one-piece toilet?
The biggest advantage is the streamlined, easy-to-clean design. Because the tank and bowl are fused into a single unit, there’s no gap or seam between them. This eliminates a common spot for dust, hair, and germs to collect. It makes wiping down the toilet much quicker and more hygienic. Many people also prefer the modern, sleek look of a one-piece model compared to the more traditional two-piece toilet.
Are one-piece toilets harder to install than two-piece toilets?
They can be a bit more challenging because the entire unit is one heavy piece. A standard two-piece toilet allows you to lift the bowl and tank separately, which is less physically demanding. Installing a one-piece toilet often requires two people to safely lift and maneuver it into place without damaging the porcelain or your floor. The actual connection to the water supply and drain is the same, but the weight is the main factor.
Do one-piece toilets flush better?
Not necessarily. The flushing performance isn’t determined by whether the toilet is one or two pieces, but by the flushing technology inside. Both styles can have excellent flushing systems. What you should look for is the specific flush mechanism, like a powerful gravity-fed system or a pressure-assisted one, and its MaP score. A well-designed one-piece toilet will flush just as effectively as a well-designed two-piece model.
Why are one-piece toilets generally more expensive?
The higher cost comes from the manufacturing process. Creating a single, seamless unit from vitreous china is more complex and requires more precise craftsmanship than making two separate pieces. The result is a more durable product with fewer potential leak points (since there’s no tank-to-bowl gasket), but you pay a premium for that design and construction quality.
What should I measure before buying a new one-piece toilet?
You need to check two key measurements: the rough-in and the overall dimensions. The rough-in is the distance from the wall to the center of the floor drain pipe. The standard is 12 inches, but 10-inch and 14-inch rough-ins also exist. Getting this wrong means the toilet won’t fit. Also, measure the space you have for the toilet’s length, width, and height to ensure it won’t be too tight, especially with an elongated bowl. Doing this homework will help you find the perfect fit from a list of the best one-piece toilets for your home.
Is a comfort height toilet right for everyone?
While comfort height toilets (around 17 inches) are great for most adults, they might not be ideal for very young children or shorter individuals. For kids, a taller toilet can make it difficult for their feet to touch the floor comfortably, which is important for proper posture. If your household includes small children, you might want to stick with a standard height model or keep a sturdy step stool handy.
