Why does my toilet keep running after flushing?

A constantly running toilet is almost always caused by a faulty flapper valve, a float set too high, or a worn fill valve. Start by checking the flapper — if it does not seal flat against the drain seat, replace it. This is a $5-$10 fix that takes under 10 minutes.

How do I unclog a toilet without a plunger?

Pour one cup of dish soap and hot (not boiling) water into the bowl and wait 15 minutes. The soap lubricates the clog and the heat breaks it down. If that fails, a toilet auger will clear 95% of clogs without a plunger.

What is the best toilet brand in 2026?

TOTO leads for flush performance and longevity. Kohler is best for design variety. American Standard offers the best value under $300. The right brand depends on your rough-in measurement, bowl shape, and budget.

What is rough-in measurement for a toilet?

Rough-in is the distance from the wall behind your toilet to the center of the floor drain bolt holes. Standard US rough-in is 12 inches. Buying the wrong rough-in size is the number one installation mistake homeowners make.

Frequently Asked Questions

ADA Standards for Accessible Design (Section 604.4) require the top of the toilet seat to be between 17 and 19 inches from the finished floor. This is measured to the top of the seat surface — not the rim. “Comfort height” toilets with a rim of 16–18 inches plus a standard 0.5–1 inch seat will usually fall within the ADA range.

“Comfort height” is a marketing term — it means the toilet rim is about 16–18 inches high, taller than a standard toilet (14–15 inch rim). ADA height is a legal specification: the seat surface must be 17–19 inches from the floor. A comfort height toilet with a standard seat will usually meet ADA requirements; a standard toilet usually won’t without a raised seat.

Yes. A raised toilet seat adds 2–5 inches to the seat height, which can bring a standard 14–15 inch rim toilet into the ADA range. Look for raised seats with locking side brackets that prevent wobbling — a loose raised seat is a serious fall hazard for exactly the users who need ADA compliance most. Seats with arms provide additional stability.

ADA requirements are mandatory for public accommodations and commercial buildings, but not for private residences. However, if you are building or renovating a home for someone with a disability, or planning for aging-in-place, meeting ADA toilet height standards is strongly recommended. It also improves comfort for most adults regardless of mobility needs.
