A comfort height toilet sits higher than a standard bowl, often around 17 inches to the seat, similar to a chair. Many are labeled ADA height by their makers. The choice also comes down to one-piece or two-piece build, flush volume, rough-in distance and bowl shape.
The six toilets below cover one-piece skirted models, two-piece models from TOTO and Kohler, and a black two-piece. Sizes, flush figures and features come from each product’s listing page. We have not used these toilets ourselves. Water-use figures and height claims are the makers’ own.

Mistakes to Avoid
