The toilet bowl utilizes a patented new installation system for easier, more intuitive installation. The skirted trap way installs to the floor flange and attaches to the toilet, eliminating the need to drill holes for a standard while offering the same secure installation as non-skirted toilets.

Do you realize that the height of the bowl isn't stated anywhere!?! Not in the specifications; not on the website; not in the reviews. And not from the Chat. Really? Are you kidding? :D. Johng737. San Francisco. Thu May 11 2023

Tornado flush elongated wall-mounted standard height bowl exemplifies eco-friendly cleanliness and power in commercial spaces. Engineered for optimal performance along with the eco-power flush valve, the toilet offers superior performance while saving water. Newly redesigned, this bowl features tornado flush, a rimless, hole-free design with dual nozzles that create a centrifugal washing action that assists in rinsing the bowl more efficiently. Cefiontect adds an exceptionally smooth glaze that minimizes waste from sticking to the ceramic. This coupled with tornado flush, assists to reduce the frequency of toilet cleanings by minimizing the usage of water, harsh chemicals, and time required for cleaning. The toilet bowl is WaterSense certified. Includes bowl and bolt caps. The flush valve was purchased separately.

Looks great. Only for commercial use and requires 3/4” water supply.. Ali. East York, ON. Mon Mar 10 2025

The floor-mount flushometer bowl features a revolutionary flushing engine and refined aesthetic design. Measuring 16-7/8 into the top of the rim, the product meets both ADA and CSA height requirements. The Ultra engine represents a breakthrough in flush performance, tolerating a wide range of water supply conditions found in R&R and new construction. The product is listed from 1.1 to 1.6 GDF but can operate at 1.0 GDF. It performs well at every flush interval, making it uniquely effective with dual flush valves, and has been proven with all manner of valves (diaphragm, piston, manual, and electronic) from a variety of manufacturers.

Excellent. Kwong Pang. New York, NY. Fri Feb 12 2021

The toilet bowl delivers a powerful, clean, swirl-flush performance. Kohler's most complete flush ever. Revolution 360 swirl-style flushing technology keeps your bowl cleaner longer than a conventional flush.
