Wet rooms – the essential guide to creating the perfect space

Want a wet room, but not sure whether it will work in your home? Read on for the advantages and disadvantages of wet rooms, along with some expert design tips

Wet rooms are becoming more and more desirable, and they’re a great way to add value to your home. But how exactly do you go about designing a wet room? We’ve put together a handy guide with everything you need to know, from what tiles to choose to specialist wet room companies you can contact about installation.

So, can anyone have a wet room?

In theory, yes. Wet rooms are basically shower rooms that do away with the shower screen and tray, and has an open, fully tiled shower area. If your bathroom is on the small side you probably will need to include a shower screen to prevent everything getting sprayed.

Wet rooms: some points to consider

Water drainage
Installing a wet room is a job for the professionals as a gradient needs to be created along the floor to channel the shower water into a drain and then the entire room needs to be tanked (waterproofed).

The most common method for creating a gradient is to install a sub-floor made from WBP Ply (a type of plywood), which is then tiled over.

Another option is to install a ready-made sloping shower former (a bit like a giant shower tray), which is also then tiled over.

A final method is to use a giant preformed tray (sometimes known as a Hi-Macs system) that slopes towards a drain, and can be fitted across the entire floor without the need for tiling over.

Waterproofing
Waterproofing the wet room involves priming the floor, the lower section of the walls and the whole of the wall area around the shower and then covering with a syrupy membrane. Once it’s set, the room is then tiled.

It’s also worth raising the bathroom door threshold by about 5mm from the floor in case the room fills with water (if someone covers the shower drain with a towel, for example). This will keep the water contained.

Advantages of a wet room

  • A wet room is super-stylish and perfect for creating a contemporary look.
  • As a second bathroom, a wet room can easily increase the value of your home.
  • Great for small bathrooms – removing the bath creates loads more space.
  • Wet rooms are, in general, easier to clean. There’s no shower screen or tray to worry about and if you go for a wall-hung sink and toilet, it’s easier still.
  • If it’s done properly, your floor (the bit under the tiles) is better protected than it would be in a standard bathroom.

Disadvantages of wet rooms

  • In small bathrooms, watch out for wet towels and loo roll caused by spray from the shower.
  • You’ll need a professional fitter to waterproof the room – if it’s not done properly leaking water can cause damage.
  • Wet rooms should be tiled from floor to ceiling – and that’s expensive. And if you go for porous stone tiles, they may need to be resealed every few months, which is hard work.
  • Swapping a main bathroom for a wet room could make your home less saleable – buyers want at least one bath.

Your wet room questions answered…

What will it cost?
The cost of installing a wet room is usually between £5,000 and £10,000. If you are paying a company to tank and install the wet room, including floor-to-ceiling tiles, suite and shower, expect to pay more. Retailers such as Victoria Plum and Wickes may offer you some ideas or may sell you those little extras you need to complete your wet room.

What type of surface materials should I use?
Tiles are the most popular wall and floor covering, but you can opt for sheet vinyl for the floor, or even Corian, which is a seamless, non-porous material that is low-maintenance. Concrete and tadelakt (a waterproof plaster from Morocco) will lend your wet room a rough luxe look.

If you are going to use tiles, choose non-porous bathroom tiles like ceramic or porcelain. Porous tiles, such as slate, marble and limestone need sealing every few months to prevent water damage. Only use floor tiles specifically for bathrooms on the floor so they aren’t slippery.

Can I install underfloor heating?
Many fitters recommend installing underfloor heating as it keeps the tiles warm underfoot and helps to dry out the water on the floor.

Wet room decorating ideas to consider before you start

Think through your shower options

Decide whether or not you want shower valves to be exposed or concealed. Exposed shower valves work well in a modern country scheme and are also easier to install. But if you want a super-sleek look, a fixed rainwater shower head with concealed pipework can’t be beaten. However, if you only install a fixed shower head, it can be hard to avoid getting your hair wet – annoying if you don’t shampoo every time, and they’re not terribly useful for cleaning the shower. The best solution is to add a diverter to an adjustable hand shower.

Side-by-side showers are perfect for bathrooms designed for sharing,’ says Jonathan Carter at Victoria & Albert Baths. ‘It’s often a style you’ll find in luxury hotels and allows plenty of personal space, while making a bold statement. Try pairing with a freestanding tub to enjoy the best of both worlds. In this en suite designed by American agency Acre Creative, the floor has been raised and tanked, essentially creating a giant shower tray.

Choose sleek modern drainage

Longing for an invigorating power shower? Then you’ll need to install a drain that can handle high water volumes efficiently. A flush-fitting, channel-style drain collects water across its full width, effectively preventing floods. Look for a drain with an easy access dirt trap to help keep the water running freely.

Create a natural partition without glass

Many wet rooms have a glass panel for containing splashes, but that’s not the only way to section off the shower part of your wet room. A tiled partition wall is also a great way to stop water from flowing all over the room, while providing the easy walk-in access that people love about wet rooms.

Store well

Allocating a dedicated space for storing shampoo and soap inside your showering area is essential. One of the smartest solutions is niche shelving, which can be built into a stud wall at construction stage. Unlike chrome racks and rails, niche storage doesn’t encroach on your showering space. It’s important to tile the actual shelf on a slight gradient to prevent water from pooling at the back. add discreet waterproof lighting to softly illuminate.

Useful contacts

It’s best to employ a specialist company rather than a separate builder, plumber and tiler. The Kitchen Bathroom Bedroom Specialists Association (kbsa.org.uk) and the Federation of Master Builders (fmb.org.uk) both have online databases of specialists in your area. Before choosing a company, ask to see examples of their work.
