Wear and tear can leave toilet seats fitting improperly, cracked or broken. As well as being uncomfortable to use, it can be unhygienic and unsafe. Our simple guide makes this an easy DIY job.

Step 1

Unscrew Old Seat

Wear rubber gloves to protect your hands. Your existing toilet seat will be fixed to the bowl by two plastic screws secured underneath with large butterfly nuts. Unscrew both nuts completely. If the nuts are metal and rusted or corroded, they may need to be carefully cut off with a hacksaw.

Assembly of New Toilet Seat

Assembly of New Toilet Seat

Every toilet seat manufacturer has their own design of attachment points. Follow the manufacturer's instructions to assemble and insert the retaining bolts on your new seat. In the picture shown, the retaining bolts are of the snap-in variety with a rotating cuff lock to ensure they stay in place. Some designs have width-adjustable mechanisms that allow the seat to be fitted to a very wide variety of toilet designs.
