Wet rooms have become increasingly popular over the years for their convenience, practicality, and for being some of the UK’s top trends

Naturally, there are pros and cons of wet rooms, but we can easily see why they’re so popular, giving the benefits. With this in mind, how much does a wet room cost? Is it more affordable than a regular bathroom?

We’ll cover all the potential costs of a wet room installation, what you have to expect in terms of materials and labour costs, and much more in this full guide.


The Installation Costs of a Wet Room

To get your wet room project started, you will need to begin with the underlying structure and waterproofing part before the visible parts. 

The cost for installing a wet room can vary and is largely dependent on the style of finish that you’re looking for.  As a general rule of thumb, the estimated cost for a small wet room (2 x 1.5 metres) is £4000 and it will take approximately 4 days. On the other hand, a medium-size wet room (2.5 x 2 metres) will cost you on average £8000 and you’ll get it done in around 5 days. Lastly, for a large wet room (3 x 4 metres), you should plan at least 7 days and the estimated cost would be around £12000.

As you can see, wet rooms can quickly become expensive and you should also consider things like labour costs when estimating how much it will cost to get your job done. We will go more in-depth about these in our next point below.


The Wet Room Costs to Consider

When planning a wet room, there are a few elements to consider – some that are obvious such as the labour rates and some others that are often underestimated like tiles and flooring. Here is the full breakdown of the wet room costs to take into consideration.


Underfloor Heating

Underfloor heating is one of the most convenient and best optional elements to choose from when making a wet room. Not only does it provide warmth for your feet before and after a shower, but it also helps prevent the wet room from remaining damp.

Electric underfloor heating mats are easy for a professional to install and warm up quicker than a regular heating system. When you look for one to add to your new wet room, make sure it includes a thermostatic control. Many cheap models don’t include a thermostat and you’ll have to buy one separately. This means that a cheap heating system can soon turn into a more expensive one. It’s much better to buy one at the start that comes with a thermostat that’s guaranteed to match.

To buy a typical system including a thermostat, the costs will be from around £100 to £400, depending on the size of the mat and the thermostat’s sophistication.

Labour Rates

All things considered, a wet room typically costs around £15,000-£20,000 to install. Materials cost 85% of the total installation while the remaining 15% are all about labour costs.

The average cost for a wet room’s labour is from £150 to $250 per day. This can vary depending on the experience of the fitter or plumber that will install your wet room. While this can seem pricey at first, it is important to remember that 2 persons are usually needed and that it can take 7 days or more depending on the size. Lastly, if the specialist or installer buys the materials on your behalf, costs will obviously be higher reflecting their time spent.


Tiles & Flooring 

The tiles and flooring choice can significantly reduce your wet room installation costs. For instance, there will be less labour to fit the tiles, less grout and spacers needed if you go with larger tiles. 

Non-porous porcelain is always better than porous stone like marble; limestone will need regular sealing because it is porous; ceramic tiles are generally not suitable for floors but are good for walls (though they do come in different finishes). 

A high-quality floor and wall glue that will stick on both surfaces costs between £15 and £20 per bag and covers around 4 meters square. Similarly, a 2.5kg bag of flexible grout costs from £8 to £10.

The Waterproofing Costs in your Wet Room 

The most challenging aspect of this project is waterproofing (or “tanking”) the room correctly. The material, design, and colour of your shower wall can all play a role in determining how long it lasts.

Of course, the waterproofing part of the installation will increase the overall costs. But it is necessary to avoid spending a fortune on maintenance.

You should add some waterproof layers to your wet rooms as you will have fewer expenses over the years and eventually increase your property value.

Lastly, for the costs to consider, you should also plan some part of your wet room budget for the decor. In fact, you will want to design your wet room and some elements will definitely be pricey.

Planning Permission for a Wet Room in the UK

A wet room may be built within an existing portion of the house without requiring planning permission. But, since wet rooms must adhere to building codes, there are two things to consider. 

While the construction of the original bathroom should already be in compliance with building rules, wetrooms need adequate ventilation to allow steam to escape in a safe way. On top of that, it should be safe from the electric point of view.


Can Any Bathroom be a Wet Room?

A wet room is a bathroom that is designed to be wet entirely. Floor-to-ceiling tiling, waterproof layers, and a shower exposed to the elements are examples of wet rooms. 

Wet rooms are incredibly fashionable at the moment, and it’s easy to see why: they’re practical, accessible, and may even boost the value of your property.

All things considered, yet, any bathroom can be a wet room since the main difference is having no separate sections in the latter.

But, you should keep in mind that a wet room has to be waterproof and, therefore, you will need to add that extra layer of protection when converting your bathroom.

Wet rooms are very popular among property owners right now. They’re practical, accessible and will even increase the value of your property over time. The installation process can seem daunting at first glance, but if you keep in mind that there is no need for a separate shower section or bathtub area, it becomes more manageable.
