Bathroom Wall Panel Sizes

Bathroom wall panel sizes cause a lot more confusion than they should. Not everyone understands metric sizing and even those that do can get overwhelmed by the range of different options. Hopefully this guide will help.

The first thing to say is that the size of the panel does not affect its ability to perform its task. All panels are waterproof, all panels can be used in showers.

A large proportion of the panels on sale in the UK are made in widths of 250mm. They are usually sold in packs of 4 so that 1 pack will cover 1mt wide. This makes calculating the requirement for your bathroom a little easier. There are , however, other panel sizes available. These might be suitable for different applications such as inside shower cubicles and on bathroom ceilings.

Here we list the bathroom wall panel sizes available by width, length and thickness.


Bathroom Wall Panel Widths

The common options with regard to panel widths are as follows:


Some of our panels have a plank effect built into the design. The plank pattern is moulded into the panel so that each panel appears to be 2 planks.

Wider panels are very popular for use in shower cubicles because they can be fitted inside the unit without the need to join the panels together. If they do need to be joined together for longer runs they are tongue and grooved so they slot together without the need for a joining strip.

The joints between the panels inside shower cubicles is not a major issue. A thin smear of silicone sealant inside the join (where it cannot be seen) will put the job to bed. Many people think that you have to use large, one  piece  panels inside a shower area but this simply is not the case.

Bathroom Wall Panel Lengths

If you are fitting the panels to your walls then the standard length panels will be more than adequate. Modern houses have ceilings at around 2.1mt or 7 feet. Most panels are longer than this. Some large shower panels are a bit shorter at around 2.4mt high. 250mm wide panels tend to be at least 2.6m high.

If you have ceilings higher than this then there are lots of options open to you. You can fit a skirting board to reduce the span. Adding a large coving to the top of the room is another solution. Or you can add both if the gap dictates it.

The final option is to use an H Section Trim to join the panels end-on-end. You could run coloured panels up to the trim and then use white panels above it. This would give the appearance of a picture rail effect used in very tall Victorian style rooms.

There are also panels that are available in longer lengths from many manufacturers. These are regularly, but not always, used as ceiling panels. panels are readily available but some makes also provide 5m or 6m lengths.

The very long lengths are getting harder to source as they have proved to be difficult to transport on standard carriers. Your best bet to find these is via a local plastics supplier.

Bathroom Wall Panel Thickness

Our PVC panels are either 8mm or 10mm thick, depending on the make and range selected. All thicknesses are clearly indicated on the product’s information page.

Tthe thickness has to be taken into consideration when installing the panels, especially if the panels are part of a makeover rather than a new installation. For example, we always recommend panelling down onto the top of a bath so check that the taps have enough room behind them to cope with the extra thickness of the installed panels. Baths and basins are designed to allow for this to a certain extent as the thickness of a tile is allowed for. However when fitting panels over existing tiles it can be more of an issue as you are doubling the thickness (or more). Modern lever taps have reduced this issue as they require little or no clearance behind the tap.
