Steps

  1. Step 1

    Measure

  2. Step 2

    Buy your new seat

    Buy a toilet seat that will fit your measurements.

  3. Step 3

    Remove the old seat

    Remove the old seat by unscrewing the two bolts holding it in place. Hold the nut underneath with a pair of pliers as you turn the bolt heads with a screwdriver. There may be plastic caps covering the bolts that you'll need to pop open.

  4. If you are having trouble removing corroded bolts from the seat, spray some penetrating oil around the nut and let it sit overnight.

    Clean the holes

    Clean around the holes with baking soda to remove any dirt or rust.

    Attach the new seat

    Attach your new toilet seat by positioning it over the two holes. Re-insert the bolts and tighten the nuts by hand, then hold the nuts in place with pliers and tighten the bolt heads with a screwdriver.
