A taller toilet is one of the cheapest, most effective upgrades for bad knees, bad hips, or tall family members. Here’s how the heights compare.

The heights, explained

TypeSeat height (approx.)Good for
StandardAbout 15″Kids, shorter adults
Comfort / ADA height17–19″Most adults, aging in place
Extra tallAbout 21″Tall adults, people with knee or hip problems

The ADA accessibility standard puts the top of the seat at 17 to 19 inches. Extra-tall 21″ models go higher than that, which some people find much easier and others find too tall, so sit on one if you can before buying.

Measure your rough-in first: that’s the distance from the finished wall to the center of the toilet’s floor drain bolts. 12″ is standard, but older homes can be 10″ or 14″. The 19″ rear-discharge model drains into the wall instead. See rear outlet toilets.
