Cost of a Wetroom

Wetrooms are becoming more and more popular here in the UK due to their stylish appearance and practicality. But how much does a wetroom cost? Many factors can affect how much a wetroom will cost, so we have produced a rough breakdown as a guide.

Shower Tray Former

For a wetroom to function correctly, a slope in the floor is required to allow the water from the shower to drain away. The easiest way to achieve this is using a shower tray former. Unlike other traditional shower trays on the market, a shower tray former is built into the floor and tiled over to create a seamless finish.

At The Wetroom Store, shower tray formers can range anywhere from £100 to over £300, depending on the size and material required.

Tanking Your Wetroom (Waterproofing)

Tanking kits include everything you need to fully waterproof your wetroom, which is a vital part of installing a wetroom. It is important to remember the entire floor, as well as the walls in the immediate shower area, must be tanked. Tanking kits at The Wetroom Store start from £48.00 for a 4.5kg kit, up to £78.80 for a 10kg kit.

Underfloor Heating

Underfloor Heating is a great addition to any wetroom, providing that extra bit of luxury to your home. Not only does it give you a pleasant warm underfoot but it also helps to keep the wetroom dry. Electric underfloor heating Mats are particularly ideal, as they are easy to install and come in a variety of sizes. You also do not need to install underfloor heating in the immediate showering area as the heat from the water will heat the floor sufficiently and the slope to the drain will prevent standing water.

At The Wetroom Store, we also specialise in underfloor heating, meaning we can give you a specialised quote and give you all the information you need for a successful UFH solution.

Our underfloor heating mats start from £55, depending on the wattage required.

Wetroom Showers

Because of the vast range of showers available on the market, the price for your shower will vary drastically depending on your choice. This can range anywhere from £100 to several hundred.

Shower Screens

Shower screens are useful if splashing is likely to be a problem but otherwise are not strictly necessary in a wetroom. Shower screens start roughly from £200 upwards and will vary greatly on the size and style you choose.


The style of tile you choose can affect both the labour costs and the general cost of your tiles, so again prices will vary. Most tiles such as Ceramic or Porcelain are non-porous, however, tiles like Marble or travertine are porous, which will need to be sealed regularly. Tiles can cost anywhere between £12 to £80+ per m2.

Tile Adhesive & Grout

Again the cost of Tile Adhesives, Grout and helpful tools such as Spacers will vary greatly depending on the brand of the product and the size of the project. Here at The Wetroom Store, we recommend Atlas GeoFlex Express Flexible Gel Tile Adhesive, which for a 25kg bag costs £19.99.

Average Cost Breakdown of a Wetroom

Depending on where you are in the UK labour prices can vary anywhere between £150 to £250 per day. The time taken will depend on the amount of work required along with whether they need to rip anything out, the tiles used and the complexity of the design.

In the example table below, we have used a 4m2 room with walls of 2.3m high as an example along with a rough cost for the labour involved.

*Please note these figures do not include adding additional features such as lighting, decoration, basin or toilet, etc.
