Downstairs Toilet   /   Shower   /   Wetroom

downstairs toilet

Under the stairs in your house we can install a toilet and sink. 

Or if you have a little more space but not enough room for a shower cubicle,  we can install a Wetroom.

In a Wetroom, instead of a shower cubicle there is  a shower but no cubicle.

Instead, under the shower a hole is dug out to install a drain and then the area around it is waterproofed and tiled.

    A downstairs wetroom will cost around £2500 in labour and £1400 in materials, making a total of something of the order of £4000

                                          INSTALLING A WETROOM


The works listed below give an indication of where the figure of £4000 for installing a wetroom comes from ..

In this example we started with a small room under the stairs, with a window and a mains water inlet, some surface mounted electrics and plumbing.


There was not room for a shower cubicle so it was decided to install a wetroom.

After the layout had been decided,  holes were cut in the walls to allow for an extractor fan outlet, a toilet waste outlet and a sink outlet.

he floor was dug out in order to install a pre-formed shower tray. You can buy these from   HERE 

The ceiling was removed and pipes were taken from the existing plumbing above to run cold water to the toilet and hot and cold water to the sink and to a thermostatic shower.

( N.B. A thermostatic shower,  unlike an electric shower, feeds off the hot and the cold water supplies - ideal if you have a combi boiler or a stored hot water system. ) 

Additionally, a radiator was required, so the flow and return pipes from the radiator in the room above were brought down to install a radiator in the wetroom. 

The extra pipework required was then boxed in. The pipes are hidden behind the boxed in panel to the left of the door in the photo.


There is a section under the stairs which is too low to be useful as part of the room so this was seperated off with a small "stud partition" wall (timber and plasterboard). The toilet can then be mounted on this new wall. 

The section on the other side of the partition wall can instead be accessed from the hallway and form a useful storage area. 

In this example we installed sliding shelves and a bi-fold (folding) door to create a shoe cupboard. 

You can fit 33 pairs of shoes or boots in it - the cupboard pictured on the left only holds 12 pairs.

Back in the Wetroom, the existing light was removed and the wiring re-arranged to create 3 downlighters, and the ceiling was then re-instated, skim-coated and painted.

The Shower waste pipe and  tray were then instated and the floor and lower walls were "tanked" with a water proof paint that dries to form a sealed skin to prevent any water penetration down to the floor below.  

The walls and then the floor were then tiled and grouted.

Then the toilet, sink and shower were instated on the newly formed plumbing and the toilet waste pipe was boxed in, tiled and grouted.

Finally a towel rail, shelf, hook and door-lock were added.
