What is bathroom cladding?

Bathroom cladding, also known as bathroom panels, are panels of waterproof and hardwearing materials, typically PVC, that make transforming a bathroom quick and easy.

Why use bathroom cladding?

Bathroom wall panel

There are several benefits of using bathroom cladding instead of more traditional wall and floor tiles.


Firstly, bathroom cladding is generally much cheaper than tiles and other wall coverings, meaning that it is a great way to stay within budget on a renovation or new build project. Replacing or creating all the walls within a bathroom may be considered quite costly, but when using bathroom cladding it is a great way to update the overall appearance of the bathroom without spending too much.

Easy installation

Another major benefit of bathroom cladding is that it is incredibly easy to install, and much less labour-intensive than installing numerous wall tiles. Find out more about how to install bathroom cladding below.

No grouting required

When installing bathroom cladding, the large panels remove the need to apply grout. Grouting is not only incredibly time-consuming but also is a popular home for mould and mildew. By installing bathroom cladding you remove the need for grouting, which in turn reduces the potential for mould and mildew to form as well as preventing damp.


The completely flat and smooth surface means that not only is it highly unlikely that mould or mildew will be able to form, but it also means that any dirt or grime build-up is really easy to wipe off. This is another benefit of using bathroom cladding over tiles – the panelling is hygienic because not only is it unlikely to be able to harbour mould, mildew and dirt if it does it is quick and easy to clean.

Insulating properties

Installing bathroom cladding or wall panels is also a good way to improve insulation within your home, particularly when compared with installing tiles. By improving insulation, you will not only save on energy bills but also make your home more efficient, and can even improve soundproofing.

How to install bathroom ceiling cladding

When installing cladding on both walls and ceilings, we’d always recommend starting with the ceiling panels first to ensure a completely watertight coverage.

When installing cladding onto a bathroom ceiling, we’d recommend using wooden battens to provide a framework on which the cladding can be fitted.

Here are the steps you need to follow.

Step 1: Create a timber frame

Cut your timber battens to size, according to the length or width of your bathroom. Then fix the wooden battens at around 30-40cm intervals onto the ceiling. If desired, you can opt to double batten the roof, which helps to improve the ventilation in the bathroom, but this will lower the ceiling height so is not always possible. Once your timber frame has been fitted, check that it creates a level surface with a spirit level.

Step 2: Cut and install edging trims

Next, cut the edging trims to ensure they fit the length of each wall, before fitting the edging trims on 3 sides of the room, ensuring they overlap in the corners.

Step 3: Cut the cladding panel to size

The next step is to cut the first cladding panel to size, before installing it onto the ceiling. When cutting the cladding, a simple saw can be used, but try to keep the blade shallow to avoid rough edges. If working on a decorative panel, cut with the decorative face upwards when working with a precise handsaw, but if working with an electric saw, cut with the decorative face downwards.

Step 4: Install the first panel

If working on a tongue and groove cladding installation, remove the tongue on the first panel – this will enable the panel to fit neatly into the edge trim. Slide the panel into place, ensuring it fits into both trims and screw or nail it into position – if needed, you can also apply adhesive to the back of the panel for extra security.

Step 5: Install the rest of the panels

Now install the second panel, ensuring it fits into any edge trims as well as the tongue and groove connection of the first panel.

Continue this process until the ceiling has been covered, and then fit the final edge trim. This should create a complete covering of cladding over the ceiling.

How to install bathroom wall cladding

When choosing your bathroom cladding, you can opt for square edge fixings or tongue and groove fixings. We’d recommend using square edge fixings for shower panels, but using tongue and groove fixings for continuous panel runs.

Bathroom wall cladding can be installed directly onto the wall if the wall is relatively level and even, or it can be fitted onto a frame of wooden battens.

If working with square edge fixings, use H joint extrusions between each bathroom wall cladding panel, and use corner trims on each corner to create a complete seal. Ensure you leave a 3-4mm gap around all pipes and accessories, and seal these gaps with a bead of sealant.

Step 1: Start at the corner furthest from the door

When installing bathroom wall panels, start at the corner furthest from the door, and panel in both directions around the room until you reach the doorway – the panel above the door will be the last panel put in.

Step 2: Install the corner profile and the first panel

The first step is to install an internal corner profile into position, by applying the shower-panel sealant to the back of the profile. Then add adhesive to the back of the shower panel before putting it into place, allowing for a 3-4mm expansion gap – if working with tongue and groove fittings ensure you’ve removed the first tongue section first.

Step 3: Ensure a 3mm expansion gap is left around the fittings

When working in wet areas, seal inside each profile trim before installation, and ensure that panels are fitted with a 3mm gap above baths, shower trays and floors. Then seal the expansion gap with shower panel sealant.

Step 4: Continue installing panels

Now work outwards, panelling around both sides of the room, ensuring panels are secured with shower panel adhesive and using shower panel sealant around each joint.
