Deciding on a space alone can be quite a difficult task. If you’re lucky to have a dedicated space to creating your wet room then this makes the job quite easy and all you have to do is focus on designing your dream space.

However, if you don’t have a dedicated room to use then you may need to be a little more creative with your property, looking at options such as en-suites bathrooms or looking at creating one bedroom with a partition area – similar to the way some of the fancy hotels have started making the most of our their spaces too… how do you create a beautiful space using only 1 room that needs to be functional for both sleeping and also showering?


En-Suite Wet Room

Having an existing en-suite will make things a lot easier to plan out your space as you already have a dedicated space to work with, there are still questions that you’ll need to consider – for example; should you have a door on your en-suite or will it be open into the bedroom to make the space feel quite open and light.

One thing you may also want to consider is making sure that the design of the bathroom matches what you have done in the bedroom, for example if you have a bedroom that has quite a light and airy cream / white theme going on and it’s in a loft space, the last thing you’ll want to do is create a dark and theatrical style en-suite as the two styles will clash heavily in a space typically that is quite airy and has plenty of light from roof windows. 

Choosing the wet room flooring carefully is also something that is very important, if you have a separate drying space after being in the shower then that is fantastic, however, if you have to walk onto your bedroom carpet or a carpeted area while still drying then, in the long run, this will damage the carpet and flooring so keep this in mind.

There are more modern designs coming into fashion and especially more with the introduction of small spaces and new build apartments In cities up and down the UK. They are quite clever in terms of designs and hotels have been quick to take these designs up to maximise the efficiency of space they have within hotels as old traditional en-suites tend to take up a lot of room.

It’s becoming more typical to create a partition behind the headboard of the bed or even behind a wardrobe that is essentially it’s own space and a mini bathroom with no door, these have quite minimal functions but usually a toilet, sink and shower with drain, a wet room shower door or glass screen may be necessary to reduce the amount of splash onto carpeted areas.

You could easily achieve one of these modern all in wet rooms by taking a 1.5m to 2m x 4m minimum size along one of the walls of a bedroom.


Wet room flooring & drainage

Have you ever thought…

What kind of flooring do I need and how to I make sure the water is drained properly?

The last thing you want is to have water splashing everywhere on carpets or on areas like toilets and sinks that you’d want to ideally keep outside the shower splash zone, however, you’ll also need to think about what kind of wet room flooring you use and the type of drain you use as well.

A shower tray will naturally have its own drain built in that you will have to fit together, however, if you have an open shower with a glass shower screen then you’ll have to make sure that a drain is built into the floor of the wet room that has a small slope to channel all the water into the drain.

Flooring is also a very important factor, if you opt for a tiling option then we recommend that you go for non-porous materials because these will need to be treated to ensure they’re fully waterproof every few months which could be timely and expensive. Where as, if you use porcelain or ceramic tiles then you’ll be confident that it’s keeping water away from your floorboards and house innings.

Creating and limiting the splash zone can be done in many ways – one involves having a physical tray and an enclosure made from shower glass that keeps the splash zone contained.

There are other options such as having a glass shower screen that minimises the splash zone but means that your showering area is more open, this can often create quite a contemporary look and also make the most of a small space by keeping the area quite open and free flowing.


Wet room screens & partitions

Glass shower screens come in all different shapes and sizes. We’ve already covered opting for a glass shower cubicle which keeps everything enclosed with glass shower doors.

However, you may also opt to go for different options such as having a floor to ceiling glass partition that keeps the shower area open and spacious but also will mean that towels and toilet roll will not get wet and ruined while you shower.

If you do want to add a little privacy in your bathroom if you spare with someone else then you could always opt for a frosted glass or translucent pattern that allows the shower to be used while someone else is in the bathroom.

The toughened glass will not break easily so you do not need to be worried about installing one with kids in the house.



If you have a dedicated large space and feel that adding in a bathtub doesn’t take up too much space in the room then definitely consider having a bathtub and separate shower area to really add value to your home. You could always think about saving space and doubling up your bathtub are your showering area and having either a bath shower glass screen or simple but stylish shower curtain to stop any water splash going everywhere. There are many different types of bath tubs:

  • Freestanding bath
  • Shower bath
  • Cast iron bath
  • Freestanding slipper bath
  • Free-standing bathtub
  • Freestanding double-ended bath
  • Luxury freestanding bath
  • Freestanding acrylic double ended roll top
  • Corner left bath
  • Inset bath
  • And much more

Planning on building or designing a new wet room and not sure where to start?

Turning your spare space, bedroom section or bathroom into a wet room can be relatively straight forward. Having a walk in shower is a fantastic style choice and will really add some character to your property but remember that they also have practical benefits. If you have a walk-in shower rather than a wet room shower tray, it means getting in and out of the shower is incredibly easy and especially if you need a disabled shower cubicle or for it to be easily accessible.


Flow Rates

Understanding and acknowledging the flow rate required to install your shower properly while you’re in these planning stages of the project. This will help you understand and plan the correct amount of drainage that you’ll need. A standard shower will have an average water flow rate of about 24llm. More powerful showers like monsoon showers will, of course, need better drainage to compensate for the extra water.

It is understood that high flow rates for drainage can be achieved in wet rooms however the reality is that they’ll never have the capacity like a bath, so do be careful when choosing the drainage.



Compared to a few years ago, now we’re in 2017 – drainage is very modern and is just as much a part of a beautiful design as the actual shower elements and design of the room its self.

You’re no longer limited to having an awful looking metal cap in the middle of your room, you can get an infill grill which allows you to put your flooring in the middle of the grill which allows for little ‘inflow vents’ on the sides which looks very sleek but stylish. You can also place more than one grill next to the other to increase flow rates if you do have a walk in shower like a monsoon shower.



As we mentioned in the initial part of the guide – waterproofing your room (also known as tanking) is very, very important. If you don’t do a proper job of this you’ll risk damaging timber on the house or the floorboards which can seep through to any lower floors and walls and cause damp due to wood drying out.

When you’re building your wet room, you should make sure that you use some form of an impermeable membrane which goes well beyond the showering area, and also remember to do the same on the wall where your shower is located. All of the corners and wall junctions also need to be waterproofed and tanked to make sure that water does not escape the showering area and beyond the tiles/flooring / walls.



The finishing piece of creating a beautiful wet room space and adding some real walk in shower personality and style. Make sure you establish early on what kind of tiles you would like for the floors and walls.

The main key is remembering to buy a non-porous tile else you’ll have to retreat the tiles every few months to ensure that water doesn’t escape through to your non-permeable membrane underneath. You’ll also need to make sure you use proper floor tiles else they will become very slippery when wet – and incredibly slippery when you use soap in the shower you’ll have no grip at all and could cause injury.


Wet room underfloor heating

The icing and cherry on top of the cake is underfloor heating and you can plan this into your build early on. Having heating under your floor will mean that you won’t need to install any radiators to the tiles or have a towel heater (unless you want one for warm towels when you get out the shower) however this means that on those colder winter mornings that you have warm feet and also it will help dry off the floor after your shower.
