A wet room is a completely waterproofed bathroom with a walk- in shower that is level with the rest of the room. A wet room removes the need for an enclosed shower cubicle, though glass screens can still be installed to contain the water.
On a timber floor, a floor former or “dec” is installed on top of 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 can be achieved by installing a ‘Linear Screed Dec & HBL-50 levelling compound’). The level floor achieved within a wetroom means that they are the ideal solution for those with mobility issues. Our wetroom systems have been designed for use with floor tiles.

Waterproofing is the key to a successful watertight wet room. For a wet room to be completely watertight, a waterproof membrane should be installed prior to tiling. This involves waterproofing or “tanking” the wet room using a waterproof membrane underneath the tiles right up to and including the drain, corner junctions, toilet flange and recessed areas including shower niches. 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.
Wetrooms are a popular addition to homes thanks to their flexibility. Even the smallest of space can be fitted with a wetroom without the constraint of having to install a standard size shower tray.
Installing the correct wetroom system for the floor build up is critical and will ensure that it is not only watertight but it has a strong enough sub base on which the wetroom gradient is formed.
On timber floors, a wetroom former or dec is installed prior to the drainage and waterproofing systems. As the floorboards will need removing to allow the former to be installed, it is important that the former is strong enough to withstand significant weight. We always recommend that our decs are installed on top of ply support for added strength.
On newly constructed concrete floors in new build properties, the drainage and connection to the mains needs to be installed prior to the screed being poured. In older properties, the old screed needs to be removed or ‘scabbled out’ before the drainage system can be installed. The new screed is then laid on top.
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 150 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. Visit our Underfloor heating blog here.
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 you have established your floor build up, it’s advisable to decide upon 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. (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.
Wet Room Installation FAQs
A wet room can be installed on either a timber or concrete floor.
On a timber floor, a floor former or “dec” is installed onto the joists to create a gradual slope that replaces the need for a traditional shower tray. The whole room is waterproofed following the installation of the floor former and drainage systems and before tiling commences.
The whole wet room is then waterproofed prior to the installation of tiles. For more information about wet room drainage systems that can be installed on timber floors, check out our timber floors page.

An S1 or C2 cementitious rapid set tile adhesive is absolutely essential and must be used on top of the waterproof membrane. Flexibility is important, as there is constant movement within the floor, especially when the floor structure is timber.
When applying the adhesive, the 100% bed of adhesive method must be used rather than the dot and dab method. This prevents water tracking through the gaps under the tiles, leading to leaks.
We are regularly asked this question by customers. Thanks to the depth of the stone they’ve used on the wetroom floor and the addition of 100% bed of adhesive beneath the tiles, the grill doesn’t then sit level with the finished height of the floor tiles. Thanks to the flexibility of our brackets and drainage grills, it is easy to adjust the height of the grill to match the depth of the tiles. We supply a pack of spacers with every grill that can be used to adjust the height up and down according to your tile depth. If you require deeper screws or spacers, please contact your supplier.

Wetroom Design FAQs
A Stone-Infill Grill is a stunning way of creating the look of a continuous stone floor, virtually unbroken by the line of a stainless steel drainage grill. The Stone-Infill grill is suitable for use with natural stone and porcelain tiles, which are simply bedded into the empty Infill Grill, creating a beautiful finishing touch to any wet room. Suitable for use with the popular Modular Wet-Floor System for timber floors and the Linear Screed Drain for solid floors, the Stone-Infill Grill adds a sleek and minimalistic feel to any wet room. Our Frameless grill is a stunning addition to your wetroom and is the ultimate Stone-infill grill without a frame. A natural stone or full bodied porcelain tile can be used in our frameless grill surround. Find out more information about the Stone-Infill grill here.
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. Vinyl drains need a clamping ring which our drains do not have, so you will need to speak to a vinyl drain specialist.
It is now possible to complement the sanitary and brassware in your wetroom with a stunning frameless grill from CCL Wetrooms. The frameless grill enables a piece of natural stone or porcelain tile to be inserted into the base. The grill only has a 5mm shadow gap around it’s perimeter and has no visible frame, creating the look of a continuous stone floor. The frameless grill surround creates the illusion of a floating tile and will complement all of the different brassware finishes that are currently trending.

A wall grill sits flush against either of the shower walls. The grill has a 36mm lateral movement that allows it to be adjusted slightly away from the wall, dependent on the thickness of the tile. For customers who prefer to not stand on the drain, the wall grill is the ideal choice. A floor grill is positioned offset within the main shower area.
Generally our linear drains are fitted with one trap that can cope with water flows rates of up to 24 l/min – suitable for a standard showerhead. However, an additional two traps can be fitted to each linear drain to increase the flow rates up to 70 l/min, ideal for high performance showers.
Installing a glass screen in a wetroom is a personal choice. An entirely waterproofed wetroom will do away with the need for a glass screen as the tanking will act as a secure barrier to contain the water. However, if you have small bathroom, you’ll probably want to install a glass screen to stop the spray soaking your towels and toilet rolls, which can travel up to 1200mm from the centre of the shower head. A glass screen will also help to create an illusion of space within your wetroom.
One thing to bear in mind if you decide to install a glass screen is that you will need to purchase a decorative tile trim (edging strip). The stainless steel trim is used to conceal the edge of the tiles that are visible along the length of the wetroom tapered board once it has been tiled upon. Just ensure that you buy a tile trim long enough to accommodate the size of your tapered board and drain body. The tile trim can be cut down on site.

The demand for effective shallow drainage has never been greater thanks to the reduction in floor depths in today’s modern residential builds.
At a depth of only 55mm, our Linear Screed Drain with waterless Lo-Seal Trap has been developed specifically for use in wetroom construction projects with screed depths of below 70mm. The trap contains a self- sealing mechanism which locks into position, keeping the trap sealed when not in use. The slimline drain has been granted BBA approval, and allows the waste position to be rotated through 360°, enabling easy installation into any concrete floor, as well as connecting to existing pipework on-site. For full technical specifications, please visit the Linear Screed Drain page.
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.
