How to Choose a New Toilet Seat
Ask This Old House plumbing and heating expert Richard Trethewey discusses the basics of choosing and installing toilet seats
- Start by measuring the length of the toilet seat. They come as either round seats at 16” or elongated at 18”. Be sure to buy the correct size seat.
- Unscrew the bolts at the back of the toilet seat holding it in place and remove the old toilet seat. Depending on how old the toilet seat is, this may require a screwdriver if the screws are on top of the toilet. If they’re underneath, it’s safest to use a socket wrench to unscrew the bolts.
- If the old bolts have become deformed and won’t loosen up, carefully cut them off with a hacksaw. It will be easier to cut them from the top. Place a putty knife underneath the saw to protect the china of the toilet from being scratched.
- On the new toilet seat, place the holes on the back of the seat over the holes on the toilet.
- Insert the screws that come with the toilet seat into the holes on the toilet. Put the nuts on the underside of the toilet.
- Tighten the screws with a flathead screwdriver.
Richard distinguishes between Round (16”) and Elongated (18”) toilet seats. Replacement seats must match the existing toilet seat.
