3. American Standard Champion-4
The Champion-4 Right Height One-Piece Elongated Toilet is manufactured by American Standard and has the company’s Ever Clean Surface. This surface inhibits the stains and growth of bacteria, mold, and mildew, keeping the toilet cleaner for a longer time. The Ever Clean Surface is specifically designed to reduce staining and to hinder the growth of mold, bacteria, and mildew. Consequently, keeping the toilet cleaner for a longer time.
American Standard Champion 4 uses a flushing system having a 4” high-pressure piston to give a high-performance flush, i.e. delivers a high pressure 1.6 gallons flush. However, the 1.6 gallons per flush means that it is outside the Water Sense guidelines and does not qualify for the exemption. The combination of the levered flush mechanism, the height of the seat, and the shape of the bowl all make the American Standard Champion 4 ADA-compliant.
The American Standard Champion 4 is a one-piece toilet with a combined cistern. The 2 3/8” trap way of American Standard Champion 4 allows the waste to pass smoothly to the drainage system. Moreover, the flush system has been tested as capable of dispensing 2.2 lbs of waste in a single flush. The American Standard Champion 4 encompasses a high-pressure flushing system combined with the Ever Clean surface of the bowl, which ensures that the toilet flushes completely and properly in a single flush.
The toilet is designed to fit a minimum of a 12” rough-in. And as the American Standard Champion 4 is a one-piece toilet thus, it is heavier than the individual parts of a two-piece. This weight makes the Champion 4 a little more difficult to position it over the rough out. Therefore, rather than doing it on your own, it better be done as a two-person job.
- Ever Clean surface to prevent the buildup of stains
- high-powered flush
- 2 3/8” fully glazed trap way
- ADA compliant (when a suitable seat is fitted)
- 10-year warranty
- Does not meet EPA Water Sense requirements

5. Toto Neorest 700H
A toilet as high-end as the Neorest undoubtedly deserves the best of TOTO’s toilet functions. Since this is a tankless toilet, thus all of the superpowers are contained in the bowl, including the electric pump that performs all of the heavy liftings when flushing.
However, the high-capacity electric pump is only half of the tale. Every detail, from the bowl surface to the water channels, is designed to enhance the cleaning power for full waste elimination. The CeFIONtect glaze on the glazed bowl surface is one of the most important components in waste disposal.
TOTO employs CeFiONtect, a non-porous glaze on its ceramic bowls. It prevents trash from sticking to the bowl’s surface, no matter how small. As a result, water can easily carry them away. Consequently, just 1.0 gallons of water are required to eliminate the solid waste.
The waterways, which are internal channels in the bowl, come next. Their function in the TOTO smart toilets is to direct water flow via apertures at the bowl’s top and bottom. The top opening is for washing the bowl. A powerful stream of water will spiral down from the rim, sweeping everything in its path all the way to the bowl outlet. On the other hand, the one at the bottom pushes everything through the trapway and into the drain pipe.
This Tornado Flushing System is also found in some of TOTO’s top high-end gravity flush toilets. It is a one-of-a-kind and industry-leading siphonic flushing mechanism. Moreover, the Tornado Flushing System’s rimless bowl shape in TOTO smart toilets is its best feature.
It lacks the traditional rim holes that run the length of the bowl rim. As a result, dirt and bacteria have nowhere to hide, resulting in a more sanitary toilet. It’s also a lot easier to clean with the CeFiONtect glazing because you don’t have to use any harsh chemical-based cleaners.

- Quality materials
- Automatic flush
- Easy to clean
