Thanks to their size and space saving nature, wall hung toilets are growing in popularity. They can increasingly be found within many main family bathrooms, en suites and also are commonly used within commercial premises.

A wall hung toilet is also often used for bathrooms that want to create a more minimalist design. The neat design allows this toilet area to be kept clean, that’s because quite often the majority of the toilet is hidden behind a false wall or a cabinet.

Before we start looking at how to install a wall hung toilet it’s important that if you decide a wall hung toilet for your bathroom, you seek a professional fitter or plumber to install your wall hung toilet.

Here’s the tools and the materials needed in order to fit a wall hung toilet system:


Wall plugs

Jig-saw cutter


A socket set

Sealant gun

Silicone sealant

Wall hung toilet system and frame

Waste pipe connector

Copper pipe and connections if needed

Step one: Remove the old toilet system

Remove the old system completely. Remove any remaining brackets, screws or objects that may be where the new wall hung toilet will be attached.

Step two: Mark out wall and floor

Different wall hung toilets require different attachments in order to fix to your wall. Make sure you read the instructions carefully and pencil on the floor and wall where you will attach the new wall hung toilet frame.

Be as accurate as you possibly can, that’s because the floor screws will need to marry up with the wall screws to attach correctly to the wall. Therefore take some time measuring up the distance between where you plan to drill the wall and the floor.

Drill the wall and floor with the right millimetre drill bit. Then put in place wall plugs, do ensure that the wall plugs fit tightly into the hole to prevent movement of the toilet possibly occurring later on. Then use your socket set or screwdriver to fasten the toilet frame to the wall and then the floor.

Some frames are adjustable up and down, make sure at this point you have the frame at the correct height.

Step three: Attach the frame to the wall using the bolts

Normally a wall hung toilet frame will have bolts and a wall attachment. Use the bolts to attach the frame to the wall.

Step four: Fit the soil pipe and inlet water supply

It’s normal for the water supply to now be at a different location than your last loo. Use the services of a qualified plumber to obtain pipe work to the cistern. Fit the new soil pipe, the wall hung system normally has fixings to make sure the soil pipe stays connected.

Make a surround for the wall hung frame, use what material you like. Wood is normally used because it allows for the holes to be easily made. Use your electric jig-saw to make holes for the flush mechanism and also to allow for the soil pipe etc.

Step Five: Attach the soil pipe to the wall hung toilet frame.

Some installers raise the surround slightly off the ground in order to allow for tiles to be fitted underneath the toilet surround.
