How To Fit A Toilet Seat

Fitting a new toilet seat is an easy and cost effective way to give your bathroom a refresh. In this article we outline how you can remove your current toilet seat, then measure and fit a new one.

Before You Start

Tools You'll Need:

  • Adjustable Wrench
  • Screwdriver

Measuring Your Toilet Seat

To determine which toilet seat you need, you'll need to remove your current seat and measure it.

  • Measure from the middle of the two fitting holes to the centre of the front of your toilet.
  • Measure the width of the bowl at its widest point.

Taking these measurements will help you determine which size seat you'll need. If you need to purchase a new one, take a look at the excellent range of toilet seats available at Tap Warehouse


How To Remove The Old Toilet Seat

1. Press the Button and Remove From Quick Release

Most modern toilet seats will have a quick release button to help you take it on and off easily. Press the button and lift the seat up.

2. Remove The Fixing Caps

With a screwdriver, lift up the seat fixing caps to get to the bolts underneath.

3. Unscrew The Bolts

With your screwdriver, unscrew both of the bolts.

4. Remove The Toilet Seat Fixings

Now you have loosened the them, you can take the bolts and fixing kits off on both sides.


Removing A Traditional Toilet Seat

1. Remove The Nut Underneath The Toilet

Underneath your traditional toilet you should be able to find a nut. If this is a wing nut you will be able to remove it by hand but if it's a standard nut, you'll need to loosen it with a wrench or pliers.

2. Lift Up The Seat

After removing the nut you should be able to pull up the seat and remove it along with the bolts.

Fitting The New Seat

Now you've removed your old toilet seat, it's time to fit a new one. This guide shows you how to install a top fixing toilet seat. For bottom fixing seats, see the guide below.


1. Fit The Plastic Plugs

Fit the two plugs that came with your toilet seat into the holes in your toilet pan halfway.

2. Fit The Hinge

Fit the metal washer on top of the plastic plug then add a hinge on top of the washer.

3. Attach The Bolts

Fit the bolts into the hole on the hinges and tighten with a screwdriver.

4. Adjust The Seat

Push the toilet seat into the quick release hinges and adjust it until it's in the correct position. You may need to tighten the bolts further at this point. 

5. Fit Hinge Caps

Once you have adjusted the seat correctly, remove the seat from the quick release and snap the hinge caps on top of the bolts.

6. Re- Attach the Seat To The Quick Release

With the hinge caps added all you need to do is reattach your seat to the quick release.


Installing a Bottom Fixing Toilet Seat

Some toilets may come with a bottom fixing kit, these will often be easier to fit than modern top fixings.

1. Assemble Provided Fittings

With the instructions that came with your toilet seat, assemble the fittings for the toilet.

2. Fit The Bolts Into The Toilet

With your fittings assembled, line the bolts up and fit them into the holes on both sides of the toilet.

3. Turn The Nut Underneath

Look behind your toilet and locate the bolt you've just dropped through. Screw the nut provided onto this bolt using your hand if it's a wing nut or a wrench if it's a regular nut. Don't tighten it too much yet.

4. Adjust Seat Position

Adjust the position of the seat until you're happy with it. Once you've done this you can now fully tighten the nut underneath and your seat is installed!
