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.

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.

Our 10 year guarantee covers all damage and consequential damage resulting from a leak within the tanked area. The membrane must not be torn or punctured in anyway. The tanking membrane will allow or 2mm of movement on the wall and 5mm of movement on the floor.

Q: How do I look after my wet room?

Wet rooms look after themselves in the same way as a conventional shower tray. However you must be careful not to pierce the waterproof membrane under the tiles. Should you renovate your bathroom, remove tiles or puncture the membrane, your room will no longer be water tight.

Q: Can I retro fit toilets?

Yes but you must not piece the membrane under the tiles. We suggest the use of specialist adhesives or screws that are shorter than the tile thickness.

Q: What style and type of shower drain do I need?

Shower drains are vital to the success of a wet room. The floor drains we supply have been tested and approved with our system. We stock a full range of wet room floor drains in different sizes and finishes.

Q: Does the size and style of tile matter?

No not really as it depends on your chosen floor drain; however it is important to consider the finish of the tile, how slippery will this be when it is wet? Some tiles are subject to staining with water penetration. If you have a central drain, smaller tiles are easier to lay on the sloped floor. A wall mounted drain means you can use large tiles and have less grout lines.

Q: I have a very small en suite, is it too small for a wet room?

No, as we create our wet rooms to our client’s specifications there are no predetermined sizes. Walk in showers are great for space saving!

Q: Why would I need under floor heating?

You don’t, but it does have many benefits! Under floor heating provides a warm under foot surface and it can be regulated independently from the rest of the household heating system.

Q: Do I need a glass screen?

No, but many clients prefer to section off the shower from near by sanitary ware. It also can provide a touch of class! Visit our gallery for inspiration

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.
