To be sure, it is essential that you check the manufacturer’s instructions before doing anything.

Step 5

Now you can fit your new toilet seat.

For traditional models, position the seat over the bowl and secure it by tightening the bolts underneath using a pair of pliers, adjustable wrench or the tool provided with the replacement seat.

If your toilet uses a top-fix or quick-release design, simply align the seat with the mounting pegs and press it into place, ensuring the pegs are fully inserted into the holes.

Be sure to follow the manufacturer’s instructions carefully, especially if you have a bespoke system or one designed for medical purposes, as installation methods can vary depending on the toilet model.

FAQs

How Do You Measure a Toilet Seat?

Measure the length from the fixing holes to the front of the toilet, the width at the widest point of the pan, and the height from the fixing holes to the cistern or wall mounting. It's also important to note the distance between the fixing holes, as this can vary between models.

What Cleaning Products Should I Use to Clean a Toilet Seat?

You should clean your toilet seat with soap and water. This will help your seat to remain glossy looking. You should avoid using harsh chemicals or abrasives as these can rub away paint or stain on wooden toilet seats and can leave plastic seats looking worn and dull.

What Can I Do if My Hinges Are Going Rusty?

First double check it is rust and not just dirt, by cleaning the hinges with a soft cloth and soapy water. To remove early stages of rust, try using steel wool or a wire brush - alternatively, household items such as white vinegar or mixing up a baking soda paste can also help.

Can I Paint or Customise a Toilet Seat?

Yes, although you should only use paints that are suitable for plastic or wood surfaces. Avoid harsh chemicals and ensure the surface is cleaned, if painting a wooden seat sand it lightly beforehand. Allow enough drying time before using the seat.
