Below we share some considerations when looking for a new toilet, and our top choices for the best one-piece toilets!

Advantages of One-Piece Toilets

✓ Easier to Clean

To start, with no crevices or joints, one-piece toilets have no place for dirt or bacterial buildup on their exterior, which is a big upside. They are also much easier to maintain because they have a lower chance of breaking or leaking.

✓ No Drill Holes to Support Tank

To install a standard two-piece toilet, you would have to drill holes to support the water tank. You won’t have that problem with single-piece models, making their installation process a lot simpler.

✓ Seamless Design with Fewer Separate Parts

One-piece models are often smaller, making them ideal for compact bathrooms. Plus, they have a sleeker design that fits well with modern bathrooms. Finally, single-piece toilets come as a whole unit, which prevents possible problems with shipping.

We’re starting off this list strong, with our all-time favorite – the Champion 4. This toilet is another solid choice that prioritizes water efficiency and suction strength. 

Flushing Power

This toilet uses 1.6 gallons per flush and is a leader in clog-free performance after many uses. The unit’s quiet flush can move up to 70% larger masses than most toilets because of the Champion 4 Flushing System. 

The four-inch piston Accelerator flush valve helps remove most waste loads in just one flush. The extra-large trapway also eliminates waste quickly and hassle-free. The toilet’s MaP score is 1,000 grams – it doesn’t get better than that!

The Design 

This features a “right height” of 16.5 inches, to ensure maximum comfort. It is ADA-compliant, with a comfortable elongated siphon action jetted bowl. 

The unit comes with an EverClean surface which prevents bacteria, mold, and mildew buildup. Like most toilets in this price range, it features a slow-close seat. 

The American Standard Champion 4 comes in white, bone, or linen, with a chrome trip lever. The lever can be swapped for a white, polished brass, or satin one instead. The toilet comes with a ten-year warranty.

Our Take on Reviews

This toilet was an easy install for most buyers.  The flush is powerful, leaving a clog-free, clean bowl for most reviewers.  This also comes with a soft-close seat which means one less accessory to purchase.  The tank is smaller than older models, lending itself to a sleek, modern look.

  • The Comfort Height features provide great sitting support.
  • The cleansing elements and deodorization system automatically kill lingering bacteria.
  • The occasional weak flushing mechanism

The Kohler Veil Comfort Height toilet is most distinguishable by its design. Smooth, sleek, and elegant, the toilet looks almost futuristic with its minimalist style. In addition to its interesting look, the toilet has great quality customizable features that we love. 

The Kohler Veil meets all ADA code requirements, unlike the Kohler Karing 2.0, and comes with an upgraded 17” chair-level seat, comfortable for all.

One of our favorite  Kohler Veil features is its special pump-assisted dual flush that allows peak flushing performance each time. The pump only consumes .8 to 1.19 gallons of water per flush, making the toilet sustainable and cost-effective. 

The tankless unit also easily attaches to the main water supply line. The Kohler Veil uses an in-wall insulated and durable tank and carrier system, saving you much more space than the Veil one-piece elongated dual flush skirted trapway toilet. The Veil also has an actuator plate for easy flushing. 

In the case of an emergency, the Kohler Veil includes a backup feature that works even during a power outage – with up to 100 flushes! This is a great development from the 2021 Kohler Veil which does not include flush support or any of the Comfort Height’s smart-tech features. 

Customizable Features

The toilet comes with an LCD remote control that adjusts the temperature, pressure, light, and more. With the touch of a button, you can customize the toilet to your liking. Activate the seat warmer during cold nights or utilize and adjust the warm-air drying system when you’re done. Motion-activated hands-free Quiet-Close™ cover works like a charm as well.

Cleanliness

Unlike its intelligent counterpart, the Kohler Brazn, the Kohler Veil utilizes Kohler’s UV Light Cleaning Technology which sanitizes your bidet wand, reducing bacteria automatically by 99.9% every 24 hours. Sanitization is automatic, so you don’t have to worry about cleaning after you’re done. 

While the Kohler Veil is a bit pricey, especially when compared with the Kohler Brazn and Karing 2.0’s one-piece design, we think its’ pump-assisted flushing and personalized settings make it well worth the buy. The Kohler Veil’s Comfort Height also reduces tension on your knees by elevating your sitting position nearly two inches higher than the other models, such as the Veil Wall-hung Compact elongated dual-flush toilet.

TOTO MS964214CEFG#01 Eco Soiree flushing toilet

This dependable toilet has a large, box-like base that takes up a bit more space in your bathroom than other models. 

Flushing

TOTO toilets are designed with a double cyclone flush system that uses a minimal amount of water to still clean the toilet bowl thoroughly. The toilet uses 1.28 gallons per flush in its high-efficiency Tornado Flush system. With just one press of the lever, water swirls around the bowl picking up all the waste and potential residue which is then sucked out by the large flush valve. 

Design 

The seat is designed at a height of 17 ⅜”  making it optimal for short and tall individuals alike. The toilet is ADA compliant and comes with an elongated front bowl and SoftClose seat. 

Though optional, we recommend getting the CEFIONTECT glaze to reduce bacterial buildup on the toilet’s exterior. The TOTO-patented glaze requires only a wipe down with mild soap and water. The one-piece skirted design also eliminates dirt accumulation in any nooks or crannies. 

The toilet’s trip lever has a chrome finish that prevents rusting, scratches, and scuff marks. 

Similarly, the porcelain is easy to clean and much more resistant to water and rust markings. The toilet is available in cotton, bone, colonial white, Sedona beige, and ebony (not available in CEFIONTECT). 

A 10” or 14” Unifit rough-in is sold separately.

Summary of Recent Reviews

Customers like the toilet’s Tornado flush system and fully ADA-compliant features, if the toilet is installed with the trip lever on the approach side. However, this toilet is pricier than many similar units that have the same standard features. Without a bidet or heating features, this toilet is a standard, no-frill model at a higher price than necessary.

This easy-to-use toilet keeps it simple but classy. 

Flushing

The TOTO Ultramax’s G-Max flushing system uses an extra-large siphon jet for maximum suction power and a wide 3” flush valve to pack a punch in every flush. The toilet’s fully glazed trapway also reduces the chance of clogging. The Ultramax uses 1.6 gallons per flush, which fully wipes away waste and any potential streaks. 

This model is reliable, with a relatively low flush noise level. 

More Features

Like most TOTO toilets, the Ultramax comes with the CEFIONTECT glaze to reduce any grime accumulation on the toilet’s exterior. Furthermore, the one-piece design and high-profile tank only need slight maintenance, with a simple water and soap combo. The toilet stands at a standard 15 11/16”. 

The Ultramax comes in three models: an elongated bowl with CEFIONTECT and SoftClose seat, an elongated bowl and SoftClose seat, or a round bowl with a SoftClose seat.

  • Easy to install
  • Reviews report the toilet coming shattered upon delivery

The Kohler Santa Rosa’s name isn’t the only thing that’s beautiful about the unit. 

Flushing

This toilet uses 1.28 gallons per flush. What makes the Kohler Santa Rosa’s flushing technology so strong is the combination of the AquaPiston canister, precision-engineered tank, and fully glazed trapway. Only two pounds of force is needed to flush the toilet. 

Each flush effectively swirls around the bowl to pick up any waste that’s then suctioned into the drain in a matter of seconds. 

The toilet’s canister reduces chances of leakage by having 90% less exposed seal material than traditional 3” flappers. The canister also requires less actuation force than typical flappers. 

Design 

The Kohler Santa Rosa has a Comfort Height of 16.5” that’s easy on the knees and legs. The elongated bowl distributes user body weight for an increased comfort level. The toilet comes with a Quiet-Close elongated seat as well. 

The Santa Rosa includes a bolt cap accessory pack, tank accessory pack, tank cover, and trip lever. It’s important to note that a supply line must be purchased separately. The toilet comes in white, biscuit, almond, ice gray, and black. The polished chrome trip lever is located on the left-hand side.

Buyer’s Guide

Choosing the right one-piece toilet is not always simple. There are various things to consider, which might be difficult if you are buying a one-piece toilet for the first time.

Here we’ve listed four important details to keep in mind when buying a new one-piece toilet:

Dimensions and Rough-in Requirement

Most toilets will be 12 inches from the wall, which is called a rough-in dimension. However, be sure to measure your bathroom’s rough-in before buying a toilet, in case you need a 10 or 14 inch option instead. It’s also important to keep an ideal seat height in mind to ensure you new toilet will fit every member of the family.

Water Efficiency

Water efficiency has two advantages: it saves you money while also saving the environment. But does using less water affect the flush power? Basically, most modern toilets consume 1.28 gallons of water per flush while maintaining plenty of power. Some toilets might use up to 1.6 gallons, but more than that is not water-efficient.

It’s a common belief that the more water the toilet uses, the cleaner it will be. However, high water consumption flushing leads to huge waste over time. Toilets usually account for 30 percent of water usage in an average household. To combat any water waste, modern toilets use much less water while maintaining efficiency. Look for a model with an EPA WaterSense label to ensure you purchase an efficient option.

Easy Cleaning

The obvious advantage of single-piece models is the ease of cleaning. Since the bowl and the tank are connected, there is no place for bacteria to hide. You will especially notice the difference if you’ve ever tried to clean a two-piece toilet. Additionally, the chance of leaking is minimal, since the bowl and the tank are one piece. Looking for a model with a simple and sleek design will increase the ease of cleaning.

Take a look at our homemade toilet cleaning guide 

Highly Durable

Any type of equipment, including toilets, is more durable with fewer parts. A two-piece toilet has a rubber gasket which can cause leaking over time. By looking for a simple one-piece option with minimal surplus parts, you’ll lower your risk of broken parts over time. Pay attention to user reviews and warranty options as well to ensure you invest in a durable, high quality toilet. 

Few Disadvantages

Of course, one-piece models have some disadvantages, too. First, they are quite expensive, and if you buy a cheaper model, it can be a risk, since they may be made of low-quality materials.

Also, if the toilet bowl breaks, you cannot replace it without buying a completely new toilet, as all the parts are within one piece.

Further, many one-piece toilets are usually smaller and lower height, which is not ideal for tall persons. However, if you buy a wall-mount toilet, you can place it a few inches higher to increase comfort.

In the end, the main downside to one-piece units is their weight. Because you can’t separate any part of the toilet, the full unit is usually quite heavy, which might be a problem during installation. We strongly advise you to call a professional to install your one-piece toilet, or at least have multiple people to help. As some one-piece models can be up to 90 pounds or heavier, installing one alone is almost impossible.

Installation Process

Installing a one-piece toilet is actually very simple, but the process can vary depending on the specific toilet.  

To install your new toilet, start by turning off the water supply and getting rid of the old toilet. Remove the old toilet carefully and clean any spills or excess from the floor. Then, remove the old wax ring to make sure that the new toilet won’t leak. To completely remove the leftover wax, you should use a scraping tool.

Next, ensure that there are bolt holes in the new toilet. If there are none, you will have to drill holes on the floor. But first, remove any excess material so that it doesn’t reach the wax ring.

When you are done, it’s time to install the new wax ring.  Stick the wax ring to the toilet to make sure it’s centered properly. If needed,  simply rotate the ring until everything is aligned.

To lay down a new toilet, ideally, have someone else there to help. Once the bolts properly line up with the holes on the floor, bolt the toilet down. You can complete this step with nuts and washers which are usually included in the package.

Then, install the toilet flush, and finally, the toilet seat. Seats usually have plastic screws, so you simply need to put them in place and tighten them. After you’ve done the final step, turn the water back on and you are finished. Your toilet is ready for use.
