“Getting up off the toilet is getting hard for my husband. Should we buy a tall toilet, and what does that cost?”

Quick answer: The number that matters is the seat height: 17–19 inches from the floor to the top of the seat. That’s the ADA range, and it’s what “comfort height” or “chair height” toilets are built to. You can get there two ways: a riser seat on the existing toilet, a small-aid purchase in the same $15–$150 band as grab bars and shower seats, or a new comfort-height toilet, which is a fixture plus plumbing labor priced by written quote.

The height facts

  • ADA seat height: 17–19 inches, measured from the floor to the top of the seat (2010 ADA Standards).
  • “Comfort height,” “chair height,” “right height”: manufacturer names for toilets built near that range. Check the spec sheet for the actual rim height. Adding the seat raises the final height a little more.
  • Standard-height toilets sit lower than that range. That gap is what makes sitting and standing harder.
  • Measure first. Measure the current toilet from the floor to the top of the seat, then decide how many inches you need to gain.

Option 1: a riser seat (the cheaper honest answer)

A raised toilet seat clamps or locks onto the existing bowl and adds height. Some include arms. It falls in the small bathroom-aid price band, generally $15–$150. It installs in minutes, needs no plumber, and comes off when it’s no longer needed. If the need is temporary, or the toilet is otherwise fine, this is usually the right first purchase.

Option 2: a new comfort-height toilet

Replacing the toilet costs the fixture plus installation: removing the old toilet, a new wax ring, a supply line, and haul-away. Labor rises if the floor flange is damaged or the floor around it is soft. Ask for the fixture and labor priced separately, and confirm the new toilet’s rough-in (usually 12 inches from the wall to the bolts) matches your bathroom.

Choice What it costs Best fit
Riser seat Small-aid band, generally $15–$150 Short-term need, rental homes, a sound existing toilet
New comfort-height toilet Fixture plus install; get a written quote Old or failing toilet, a remodel, long-term need
Grab bar beside the toilet See the grab bar guide Often paired with either option

Honest Downsides

  • Taller isn’t better for everyone. A toilet at the top of the range can leave a shorter person’s feet off the floor, and it can be awkward for children. If several people share the bathroom, check that the height works for all of them.
  • Riser seats must be locked on. A riser that isn’t clamped or locked correctly can shift when someone sits down. Check the fit on your bowl shape (round or elongated) and recheck the clamp regularly.
  • Risers are harder to clean and some people find them uncomfortable. That’s a fair reason to choose a new toilet.
  • Hidden floor problems. Pulling an old toilet sometimes reveals a broken flange or soft subfloor. That’s a real cost the first quote may not include.

Fit matters: the right height depends on the person’s leg length and how they stand up. Having an occupational therapist check seat height and where a grab bar should go is a common and worthwhile step. This is general information, not personal medical advice.

Rule of thumb: measure, then try a riser seat first if the toilet is sound. Buy a new 17–19 inch toilet when the old one needs replacing anyway, or when the need is long-term.

A taller toilet that fits this height range

Most comfort-height toilets top out around 19 inches at the seat. The SimpleProject ELEMAZ 21-inch tall toilet sits at 21.8 inches — the tallest standard-fit option we found — with a MaP 1000g flush rating and WaterSense certification. It was $269 at the maker’s store as of Nov 14, 2026, with free shipping and a 30-day return window.
