The key to the success of any wet room or walk in shower is a complete and resistant waterproofing system.

What is a wet room vs a shower room?
A wet room is essentially a bathroom or shower space where all floors and walls are waterproof and any water introduced into the room runs to a drain in the floor.
The difference between a wet room and a walk in shower is that in a true wet room, the space is completely open plan (although a wet room shower screen can be used), and the water flows away through a drain in the floor, whereas a walk in shower typically features one or two glass screens and a low level shower tray.
