This can be achieved either by routing the pipes through the rear wall of the shower if this is possible, or by building a false wall in front of the pipework. A Clerkenwell Plumber can build this structure.Shower unit drainage and waste.The tray can be a little tricky for draining the water as there is a need for a fall or a slight slope in the waste pipe. If the joists supporting the floor run in the same direction as the waste pipe, there may be room to fit the waste within the floor depth. If not, raise the base of the shower to provide the necessary slope of 6mm per 300mm of waste pipe. Some of the “top of the range” shower trays come with an adjustable base height.Shower cubicle walls.Stud walls should be made of marine grade plywood since the area will be very wet. This is screwed and glued to a frame of suitably spaced and strengthened timber studwork. Remember to seal all the angles between walls and the edges of the shower tray with mastic, so that there is no possibility of water percolating through.

It will accommodate the pipework between the timber uprights and also provide support for fixing the shower controls and adjustable rail for the shower head. The surface of these walls should be sealed and may then be clad with ceramic tiles using a waterproof adhesive.
