Wet Room Drain Installation - How to Install  a Wetroom Shower Outlets

The illustrations below described how to install a wet room drain or shower outlet in a wet room for both  vinyl floor and tiled floors. We have shown the vinyl floor on a wooden deck and the tiled floor on concrete, but these can equally be installed the other way round. If tiling over a timber floor the flooring should be min. 20mm marine or birch plywood. The illustrations show a Caroflow LoLine Shower Outlet but the application principles and cut-out sizes also apply to the Caroflow Standard Shower Outlet.
