Obviously, you can skip ahead of this section if you’re not replacing an existing toilet. Otherwise, follow these simple steps to remove your old toilet.
1. Switch off the water supply
Switch off the water supply at the shut-off valve and flush the toilet to drain as much water from the cistern as possible.
2. Remove water from the bowl
Using a cup, remove the remaining water from the toilet bowl.
3. Unscrew the retaining screws
Unscrew the retaining screws at the bowl’s base, and undo the screws inside the cistern that secure it to the wall.
4. Remove the toilet from the wall
From there, you can ease the toilet away from the wall, allowing the waste pipe to disengage with the pan connector.
