It's important to check that your new toilet seat will fit your existing toilet – because you can't always replace a bottom fix toilet seat with a top fix toilet seat.

What's the difference between top fix and bottom fix toilet seats?

In the UK, there are typically two types of toilet seat fixings to choose from: top fix and bottom fix.

• A top fix toilet seat is installed by feeding two bolts into the toilet pan and then tightening them from the top.

• A bottom fix toilet seat features fittings that are installed from the top and then tightened from underneath, often using wing nuts.

Most modern toilet have top fix seats because they're easier to fit and remove for cleaning. Top fix toilet seats are also used when you can't access to the bottom of the pan, such as with some back to wall toilets or modern one-piece style toilets.

Which type of toilet seat fixing do I need?

The type of toilet seat fixing that you need will depend on the type of toilet you have and the seat fixings that you're replacing. You need to make sure that the type and dimensions of the toilet seat fittings are going to fit your toilet pan.

For a bottom fix toilet seat, chances are you'll need to replace it with a similar bottom fix toilet seat. And conversely, if you have a top fix toilet seat you'll most likely need to replace it with another top fix seat.
