It's the Most Important Seat in the House...

Chances are, if you’re thinking about replacing your toilet seat, it’s likely time for a change. It’s a simple way to upgrade the look and function of your bathroom. It’s also key to good hygiene, because we sit on our toilet seat for an average of up to 27 minutes each day.

Let’s get started! Replacing your toilet seat can take less than 15 minutes, so follow these steps to successfully remove and replace an existing toilet seat.

What you’ll need:

  • Replacement toilet seat
  • Tape measure
  • Screwdriver
  • Pliers
  • Rust penetrant (optional)
  • ½” OR 5/8” socket or combination wrench, depending on the toilet seat

Step 1: Finding the Perfect Match – How to Measure a Toilet Seat

Our helpful video is a great place to begin.

Standard toilet bowls and toilet seats come in two sizes: round and elongated. To determine what size toilet seat you need, measure the length of the toilet bowl and the distance between the mounting holes.

A round toilet bowl will measure approximately 16 ½” in length. An elongated bowl is approximately 18 ½” in length. Based on your measurement, choose the appropriate seat – round or elongated – for your bowl. Our seats are designed to fit most manufacturers’ round or elongated bowls.

Step 2: Out With the Old - How to Remove a Toilet Seat

Removing your existing toilet seat can sometimes take a bit of work. With a standard wrench, a screwdriver and some rust penetrant, you'll be able to DIY your way to a new look in no time.

Toilet seats can typically be removed with either a screwdriver or a wrench. Please use caution, because your tools can easily chip the porcelain of your toilet bowl. Locate the nuts under the toilet tank and grip them firmly with pliers in one hand. Hold the nuts in place while you use the other hand to unscrew the toilet seat bolts with a screwdriver.

HINT: If the bolts are rusty or badly calcified, spray them with rust penetrant and let it sit for five or ten minutes. Try loosening the bolts again.

Step 3: Clean Slate (and Seat)

After removing the old toilet seat, take the opportunity to clean around the bolt holes. Place the old toilet seat in a plastic bag and dispose of it properly.
