Step by Step Instructions

1 Check the size of the old toilet seat
2 Remove the old toilet seat
3 Install the new toilet seat
  • Step 1. Check 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.
  • Step 2. Remove 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. 
  • Step 3. Install 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.
