Wetroom Flooring Types, Explained

Designing a wetroom involves careful consideration of the types of materials needed to ensure it not only looks great, but also functions well. Today, wetrooms can be installed in any property and they have only increased in popularity. . As a result, so too has the variety and standards of essential wet room materials and components.

For many homeowners and commercial property owners, wetrooms are a stylish and more attractive alternative to traditional bathrooms, while for others, they present a much more practical and efficient space for bathing. Whatever the reason for installing a wetroom, the materials needed to complete the finished design will depend greatly on the structural variations, and on those using it.

Do You Need Special Floor for a Wetroom?

Whilst wetrooms are suitable for almost any property, including smaller rooms, it’s important to think about what materials to use when designing the flooring. To get the most out of a wetroom, you will need think about things like:

  • Waterproofing
  • Non-slip
  • Affordability
  • Material quality
  • And more.

Wetroom Floors Construction

Wetrooms can be constructed on timber and concrete floors.

For timber floors, a “dec” or tapered board is installed within the shower area above the ply supported joists, where the original floorboards have been removed. The built-in gradient creates the fall towards the drain.

On solid flooring, the falls are created within the screed or if the wetroom is being installed into an existing property, the original concrete floor can be manually removed from the shower area and replaced with newly poured screed (and levelling compound) that creates the new falls.

Wetroom Flooring Materials

IMG_0332 Stone-Infill GrillAppropriate flooring is a vital component of a wet room, particularly because it needs to fulfil the very important non-slip function. Choose wet room floor tiles that are practical and safe underfoot, such as natural stone tiles which are far more suitable than slippery, high-gloss tiles.

However, it is possible to have certain wet room flooring materials designed with a slip resistant finish to ensure maximum safety.

Depending on the type of wet room flooring material you would like to use, prices will vary, but investing in quality tiles will make all the difference to the longevity and efficiency of your wet room. Just make sure they’re properly grouted to avoid seepage, and most importantly, ensure that the whole wet room area is “tanked” or waterproofed.

What Floor Materials Can I Use?

When it comes to planning your wetroom, special attention should be afforded to the type of flooring – that is, the materials you use – in its final design. As there are many options available, the final finish can look and feel different, depending on preferences.

Popular wet room flooring materials include:

  • Tiles – Natural stone and porcelain tiles are becoming the most popular choice in wet rooms as they give a beautiful, contemporary, and hardwearing finish.
  • Vinyl – Cost-effective and available in a wide range of colours and styles, vinyl is a common choice for wet room flooring outside of the shower area. It’s also water resistant and softer than other tiles.
  • Rubber – Durable, warm underfoot, and available in a range of patterns, colours and textures, rubber is a great option for slip resistant wet room flooring.

What Is the Best Wetroom Flooring?

When it comes to understanding the ‘best’ wetroom flooring options, what property owners are really asking is about suitability of materials, whether they’re non-slip and hardwearing, and how the finish will look.

The reason experts encourage property owners to investigate and learn more about wetroom flooring materials is because there is such a range of choices. This means both customisation and creativity, which can really change how your space looks and feels.

Ultimately, the best wetroom flooring will be the one most suitable to the space at hand, whether that’s vinyl, tile or other.

Tiles are versatile, coming in a range of different materials, styles, shapes and sizes, which offers more creative choice in how the final wetroom is designed. Aesthetically, a tiled wetroom finish can make a room look more attractive, especially as it’s upgrading the style of a space used frequently.

As well as wetroom flooring, tiles are also used for the walls of a wetroom. This can complete the look, helping a space feel symmetrical and well-considered. It also removes other limitations, like matching floor design with walls.

Tiles are also popular for their longevity; if cared for, a tiled finish can be hardwearing, standing the test of time.

Types of Wetroom Tile

There is a range of suitable materials that can be used when designing and planning your ideal wetroom flooring, from porcelain to mosaics. Every material will add something different to the space. So, in order to get the most value from a wetroom, it’s worthwhile studying the types of tiles available.

Popular wetroom tiling materials include:

  • Ceramic – Made from clay, kiln-fired and finished off with a customisable coloured surface, ceramic tiles are a popular option for wet room tiling.
  • Marble – This natural stone comes in a variety of designs and colours and can add a unique, luxurious feel to your wet room. Marble is more expensive than other tile materials, but the aesthetic appeal is often worth the cost.
  • Limestone – Another natural stone, limestone is typically cheaper than marble and can create a rustic and traditional feel in a wetroom.
  • Mosaics – Mosaic glass tiles are much smaller than standard tiles, and can be costly, but they elevate the style and sophistication of a wet room. Available in a wide range of colours and sizes, they allow for a great deal of creativity, but they are most suited to traditional style wet rooms with a four way fall (square) drain.

Non-Slip Flooring for Wetrooms

The perfect wetroom flooring needs to do more than work well aesthetically. It should also be a safe and secure surface for walking on, giving you complete peace of mind that the risk of a slip-related accident is greatly reduced.

Anti-slip flooring tiles are the perfect, non-slip, safety solution for a wetroom. These are tiles made from materials that are textured rather than smooth help to increase the friction underneath your feet, meaning you’re less likely to slip. It’s good practice to check the slip ratings of tiles you’ve decided on for a wet room to understand if extra precautions are needed.

If the floor tiles you wish to use in your wet room design are smooth and more prone to slipperiness in wet conditions (for instance porcelain) anti-slip coatings are an additional non-slip option. Aside from tiles, other optional wetroom flooring materials such as vinyl and rubber work very effectively as non-slip wetroom flooring materials.

When identifying slip ratings, levels range from R9 – R13. On this scale,R9 is considered poor, whereas R13 offers the best at slip prevention in wet environments.

Wetroom Drains

IMG_6397Drains are an essential part of wet room design and installation, and the style and look of the drain required (a linear or square drain), is often the best place to start. The type of drain needed for your wet room will also depend on the floor build up. If your wet room has been installed on a timber floor, drainage systems such as the Modular Wet-Floor System or the Linear Wet-Dec should be used. These use a horizontal or vertical trap that can be fitted anywhere within the central section of the trough (making it simple to avoid joists and other such obstructions).

Alternatively, wet rooms installed on solid floors will require shallow drainage systems such as the Linear Screed Drain which is suitable for use on shallow concrete floors. The Linear Screed Drain is the shallowest drain available on the market with a minimum height of only 67mm – specifically designed for installation on concrete or screeded floors. It is among the wide range of drainage systems we supply at CCL Wetrooms.

Waterproof Wetroom Flooring Materials

Wet rooms need to be watertight, so getting the appropriate waterproofing materials installed is crucial. There are several ways to tank a wetroom, but the most effective method is having a membrane such as RIW Tilesafe installed underneath the tiles. This is a self-adhesive membrane that provides a consistent waterproof layer underneath wetroom tiles. It has a thick rubberised waterproof layer that incorporates a glass fibre mesh on one side.

Waterproofing a wetroom is no easy task, so it’s important that you seek advice and materials from professional wet room waterproofing specialists. At CCL Wetrooms we have over 30 years’ experience in the waterproofing industry and we work with a large list of clients to supply and install wetroom tanking systems in their residential projects.

Other Wetroom Materials

The following wetroom materials are optional extras that many people choose to have installed as part of their bathroom re-design:

  • Glass screens – These are not essential for a wet room, but sectioning off the shower area can help to prevent any mirrors or additional items from getting wet. It also adds a sophisticated touch to the design of a wet room and allows you to create different zones.
  • Under floor heating –Many people choose to have underfloor heating installed to keep their feet warm and to dry out the flooring after a wet room has been used.
