What is a Wet room?

Wet Rooms are waterproofed (tanked) rooms usually equipped with a walk in shower. The wet room itself becomes the shower enclosure, with a shower drain inset into a gently sloped floor in place of a conventional shower tray.

Tanking is a waterproofing procedure carried out in bathrooms, wet rooms, shower rooms and sauna/steam rooms which protects the building against moisture migration and leaks (steam, shower spray, etc). Contrary to popular belief, all wet room flooring including tiles, adhesives and grouts are permeable and therefore can allow moisture to migrate into the structure over time causing mould growth, rot, and in some cases resulting in structural damage.

Can you Install in any house or apartment?

Yes, you can replace your shower room/ bathroom in any house or apartment with a wet room. The style of your wet room may vary depending on your floor profile. If you are looking for level access showering, the shower drain needs to be installed completely into your floor. In some builds this is not possible, as you may not have enough space beneath the actual floor i.e. the depth of the flooring screed is insufficient or the wooden joists are not deep enough. We can offer wet room design and ideas.

Wet rooms design can be creative or simplistic, there are plenty of ways in which to work with the building and still achieve the wet room of your dreams.

Q: What is the difference between a wetroom and wet area?

A wet room is a room that has been waterproofed / tanked throughout. This will mean that entire floor area and the shower walls will be tanked thus providing a water tight finish, which offers full protection against leaks. A wet area is when just the shower area has been waterproofed and in some cases only the floor.
