Wet Room Frequently Asked Questions

Black and White Wet Room

Luxurious black and white marble wetroom

A wet room is a completely waterproofed bathroom with a walk in shower that is level with the rest of the room. On a timber floor, a floor former or “dec” is installed between the joists to create a gentle slope that replaces the need for a traditional shower tray.  On a concrete floor, the correct falls are created within the screed or by installing a floor former or “dec”.

For more information on what makes a wetroom check out our ‘What Is A Wet Room Page’.

The floor in a wet room is completely level with no raised shower tray, they work by draining water away through a flush drain in the shower area, down a gentle gradient.

Space Saving

  • No need for a shower tray
  • Easy installation with sheet membranes
  • Optimises small spaces

The height of luxury

  • The clean, minimal lines of a wet room offer homeowners a spacious contemporary space to shower.
  • A walk in shower creates a real WOW factor in any home or hotel suite.
  • Underfloor heating is the perfect way to keep your wet room warm and dry in the cold winter months!

Complete flexibility

  • The flexibility of a wet room means that any size or shape of wet room can be achieved
  • A wet room provides a perception of space, helping make a small en-suite feel larger.
  • Contemporary drainage grills provide a sleek finishing touch to a wet room or can be almost entirely hidden thanks to our new stunning stone-infill grills.

Family friendly 

  • A level access wet room provides a family friendly showering space with no trip hazards.
  • A walk in shower provides a safe showering area for all, regardless of age or ability.
  • Wet rooms require little maintenance, thanks to few moving parts – which means keeping them clean is child’s play!
  • A wet room should also improve the saleability of your home.

Space Saving

Thanks to our innovative designs, our wet rooms can be built onto the smallest spaces. When working on high rise commercial projects such as flats or hotels, our wet rooms offer optimal space saving floor after floor.

Sound Proofing

Our sheet membranes provide superior sound proofing against liquid membranes. This provides added comfort for both home owners and their neighbours. They also help you meet relevant compliance standards.

Ready to Tile Immediately

Wet room sheet membranes from CCL, once laid, can be walked on and tiled immediately. Unlike liquid membranes, which take 24hrs to dry, you can increase bathroom installation productivity on your site. This is ideal for larger commercial projects when time is money.

A Range of Drains & Traps

Unlike traditional shower traps, we supply a range of drains and traps to suit any wet room bathroom design. Whether you’re designing to future proof a home for accessibility, or designing to unique specifications, we have the wet room components you need.

Install on Wood or Stone

Whether you’re installing a wet room on the ground floor, or the 15th floor of a high rise hotel, our modular wet-decs can be laid on any surface. They can even bridge gaps in between wooden slats to allow installation anywhere.

To see some of our wet room designs and get some inspiration for your own project, take a look at our luxury wet rooms gallery.

A wet room can be installed on either a timber or concrete floor.

On a timber floor, a floor former or “dec” is installed between the joists to create a gentle slope that replaces the need for a traditional shower tray. The whole room is waterproofed following the installation of the “dec” and drainage systems and before tiling commences.

On a concrete/solid floor, the correct falls are created within the screed.  The drainage systems are installed onto the solid floor prior to the screed being poured and the whole wet room is then waterproofed prior to the installation of tiles. It is also possible to install a floor former or “dec” onto a concrete floor. For more information about wet room drainage systems that can be installed on timber floors check out our timber floors page.

Waterproofing is the key to a successful watertight wet room. Many people still assume that the grout used in a shower area is enough to stop water penetrating but this is simply not the case. In order for a wet room to be completely watertight, a waterproof membrane should be installed prior to tiling. This involves waterproofing or “tanking” a wet room using a waterproof membrane underneath the tiles right up to and including the drain, corner junctions, toilet flange and recessed areas. The waterproof membrane should be installed across the whole bathroom floor, followed by the application of a liquid membrane to the walls to ensure water cannot penetrate between any gaps.

Did you know?

  • Waterproofing is the biggest element of the fear factor that is sometimes associated with installing a wet room
  • Correctly waterproofed wet rooms are watertight as the entire shower area is “tanked”, unlike a shower tray, and therefore far less likely to ever leak
  • Sheet membranes (such as RIW Tilesafe and Screedsafe) are much quicker to use on the floor compared to liquid systems.
  • They are also easier to install than other systems
  • The use of a sheet membrane provides a far better guarantee than other systems. The membrane is guaranteed for the lifetime of the tiles.
  • Sheet membranes are ideal for fast track construction.
  • Everything required for waterproofing a wet room is provided in one simple kit – the RIW Tilesafe kit.

The trend towards natural stone and porcelain tiles in wet rooms has helped fuel the popularity of contemporary linear drains which lend themselves to the sleek, minimal look achieved by stone and porcelain.

It’s important to remember that the type of drainage system you use in a wet room is determined by the floor build up in your bathroom. Once the correct drainage system has been chosen – a traditional drainage component for a timber floor or a shallow Linear Screed Drain for a concrete floor – it’s advisable to establish the style of tiles that you would like in your wet room.

Contemporary tiles such as natural stone and porcelain are often described as large format tiles, due to their large nature. These tiles lend themselves to the contemporary style of linear drains, which are more straight forward to install and require fewer cuts. For this reason, contemporary tiles are best suited to wet rooms with only one or two way falls where a sleek minimal look can be achieved. NB (That’s not to say that you can’t install a square drain with contemporary tiles, but be aware that the tiles around the drain will have to be cut in quite a few places and the final result may not be as aesthetically pleasing as you desired).

Mosaic tiles are ideally suited to floors with a built in four way fall and this can be achieved using a wet dec with a consistent gradient. The drainage grill that finishes off the look of the drain is square.  Whilst mosaics are still popular in wet rooms, the additional cleaning of the grout that is needed to keep your tiles looking fresh, can be rather off putting.

We’ve launched the new Stone-infill grill which can be used in both the traditional square drainage grills as well as the contemporary linear grills. Both options create a stunning continuous stone floor in a wet room, virtually unbroken by the line of a stainless steel drainage grill.

It is a myth that wet rooms cannot be installed upstairs in your home. In fact, wet rooms can be fitted throughout the house on timber or concrete floors, using the appropriate floor formers and drainage systems for the floor build up. As long as effective waterproofing systems or membranes are installed after the drainage systems, then a wet room is perfectly watertight anywhere in the house, for the lifetime of the tiles.

You will also want to ensure your tanking (waterproofing) arrangement covers the full surface area of your floor & at least 100mm up the walls. Ceilings and floors in the immediate vicinity of the shower area should be tanked floor to ceiling to capture any water that may slip underneath the applied tiling. This way any water that has escaped will be filtered back into the waste water system & directed down to the installed drainage.

Ultimately if your tanking arrangement is well thought out & sufficiently installed it shouldn’t matter what part of the property your wet room is installed in.

Our wet room drainage systems have been designed for use with floor tiles such as stone, porcelain and marble and are therefore not suitable for use with Vinyl (Altro) flooring.

Yes, electric and piped underfloor heating can be installed under wet room tiles. We recommend that if you are installing electric underfloor heating that you do not go above 100 watts per square metre.  When installing underfloor heating, please ensure that you keep 200mm away from the drain to stop the drain from drying out. (NB The Linear Screed & Wall Drain contain a waterless trap).

Inclusive Design is becoming the general term applied to the principal of a subject (in this case, a bathroom) that has been designed for use by anyone, regardless of their age or ability. For more information on the principals of inclusive design in wet rooms take a look at our Lifetime Homes news piece.

  • Wet rooms help meet the requirements of the Lifetime Homes Standard
  • The Equality Act 2010 (replacing the Disability Discrimination Act) states that reasonable adjustments need to made for those who are disabled and experience a ‘substantial disadvantage’, to ensure they have the same experience as others in service-based environments. These adjustments could be through alterations to physical access or the way services are delivered.  Wet rooms are a perfect accessible solution for those with a disability and can be counted as a reasonable adjustment for service providers such as hotels due to their level of accessibility.
  • The level access nature of a wet room creates a barrier free showering experience.
  • Unlike a shower tray,  a wet room does not require a step up into the shower or a lip that can be tripped over.
  • Walk in showers can achieve all of the above without compromising the design of the bathroom.

We offer our customers next day nationwide delivery on all stocked items ordered before midday.
