A cracked toilet seat

Overview

It’s easy to install a toilet seat and it doesn’t take very long. There are plenty of different sizes, colours and shapes to choose from, so you’re sure to find one that matches the shape of your toilet bowl and is right for the style of your bathroom.

Steps

1Check the size of the old toilet seat

You're working with a toilet, so start by staying safe – put on a pair of rubber gloves. Toilet seats come in a variety of sizes. Check the measurements of the seat's fastening bolts to make sure you buy a seat that will fit properly on your toilet bowl.

2Remove the old toilet seat

There are two wing nuts holding the old seat on to the toilet bowl. Undo the nuts and lift the whole toilet seat assembly off the bowl. Now that you've got the lid off, take the opportunity to give the top of the bowl a good clean with disinfectant.

3Install the new toilet seat

Slide the plastic bolts into the slots on the back of the new seat. Insert the bolts into the holes at the back of the toilet bowl and screw the wing nuts into place. Once the nuts have been firmly tightened, the seat is installed and ready for use.
