Finished floor to the top of the seat. A standard toilet is about 15″, which is the whole problem.
Comfort-height range referenced in ADA 604.4 and sold as “comfort height” or “right height”.
Two inches sounds trivial. It is the difference between standing up unaided and needing a hand, because the effort of rising from a seat rises sharply as the seat gets lower.
Three ways to get there
| Option | Adds | Trade-off |
|---|---|---|
| Raised seat that clamps on | 2–5″ | Cheapest and reversible. Can shift if poorly fitted |
| Toilet safety frame with arms | 0–4″ | Adds something to push on, which often matters more than height |
| Replace with a comfort-height toilet | Built in | Permanent and stable, but a plumbing job |
Risers and frames are made for round or elongated bowls and they are not interchangeable. Measure from the seat bolts to the front rim: about 16.5″ is round, about 18.5″ is elongated. Getting this wrong is the most common return in the category.
Higher is not always better
If their feet no longer touch the floor when seated, the seat is too high. That is unstable in a different way, and it makes bowel function harder. Aim for feet flat.
