Just completed a wet-room for a lovely couple. They wanted a walk-in shower and raised height toilet because the lady had a condition which made it difficult to raise her leg high. It took a bit of time but was well worth it as they were extremely pleased with the final result.
On the back of this job, I have been to a couple of jobs where the showers were leaking through the ceilings because the builder/plumber/tiler doesn’t know how to install a water tight shower.
Note to builder, DON’T USE PLASTER BOARD IN SHOWERS, USE TILEBACKER OR SIMILER.
Hears a tip, seal the shower tray to the wall board first.
Leave a 2mm gap between the tiles and the tray and seal this gap with sanitary mastic.
The shower is then double sealed and won’t leak.
