Bathroom wall panels are large waterproof boards that you glue straight over your existing tiles. One panel of 280 × 122 cm often covers an entire shower wall, so no grout lines are left. At Dizzplace they are 3 mm thin and cost from €49 per panel — roughly €14 per m².
We deliver with our own transport in the Netherlands, Belgium and Germany for €49 to €99, depending on distance. Collection is free at three warehouses: Valkenswaard, Schelle and Dortmund, always by appointment.

Why do people choose panels over tiles in the bathroom?
Because the old tiles can stay on the wall. That saves demolition, dust, disposal costs and the one to two weeks in which you cannot use the bathroom.
A tiler is rarely at your door next week, and a demolition hammer spreads fine dust through the whole house. With panels the sequence is simple: clean, degrease, glue, seal.
A bathroom we did ourselves
A room of roughly 2.2 × 3.4 metres with a ceiling height of 2.50 m, panels straight over the existing tiles. First we took out the old shower enclosure, the cabinet and the washbasin. Two of us, and honestly: two full days, not one.
The starting point: the old tiled bathroom, before the renovation.
Day one went on demolition, cutting the boards to size and fitting them. On day two we put the cabinet back and sealed all the joints. The owner finished the rest himself, because not all of his materials had arrived yet. We chose Arctic Pearl — you can see the result at the end of day two in the photo at the top of this article.
What disappointed us: the walls turned out to be quite crooked. Because of that we could not work seamlessly, the way we prefer. We used a tile levelling system to bring the boards into one plane, and left a minimal joint between the boards which we filled with sanitary sealant. Not what we had in mind beforehand — but the honest solution for a wall that is not straight. Anyone who promises you it can always be done seamlessly has not seen your wall.
We did not apply a separate waterproofing layer. The existing tiles already perform that role, and the sealant closes the joint so no water can run behind the board. That is a judgement that stands or falls with the quality of the tiling underneath: if it is loose or damaged, this does not apply.
The adhesive consumption came out higher than the manual says. On these crooked walls, well over two tubes of 600 ml polymer adhesive went in per panel, at a board height of 2.50 m. On a flat substrate you manage with considerably less, but on an old, uneven wall count on more than you expect.
Are wall panels really 100% waterproof?
Yes, the material itself absorbs no moisture — a PVC or SPC panel cannot swell or rot the way wood or plasterboard can. The weak spot is never in the board but in the connections.
That is why the corners, the edge at the floor and the connection to the shower tray or bath determine whether your bathroom is truly waterproof. You finish those with mould-resistant sanitary sealant in a matching colour. Do that sloppily and the best panel in the world is not enough.
Does mould really disappear once there are no more grout lines?
Partly. You remove the place where mould attaches most easily, but the cause of mould is moisture and too little fresh air — and a panel does not change that.
Milieu Centraal, the Dutch sustainability advisory body, is clear about this: mould is a sign of moisture problems and insufficient fresh air, and it attaches faster to limescale and dirt, which is why they advise cleaning tiles, grout and seams in wet rooms regularly. A seamless wall therefore removes a large share of those attachment points and is much quicker to clean. Ventilation remains necessary. Anyone who tells you panels make mould impossible is selling you something.
Can you fit wall panels straight over existing tiles?
Yes, that is what they are made for. The condition is that the old tiles are firmly attached, flat, and properly degreased before you glue.
If a tile is loose, knock it out and fill the gap. A wall that bulges or steps will show through the panel, because 3 mm of material follows the substrate. On a genuinely uneven wall you work with battens instead of gluing directly.
What substrate do you need in a wet room?
Moisture-resistant (green) plasterboard, not ordinary board. Over existing tiles you glue directly, but if you are building a new wall, it has to be suitable for wet rooms.
This is the advice we give most often and that is least often written down anywhere. Ordinary plasterboard behind a panel in a shower area is asking for problems you only see after two years.
Are the panels suitable for the shower itself?
Yes, including the walls inside the shower enclosure and the wall behind the bath. That is exactly where the difference with tiling is greatest.
A tiled shower wall of 3 m² easily carries tens of metres of grout line. One panel of 280 × 122 cm has none, and you clean it with a cloth and a mild product.
PVC or SPC for the bathroom?
PVC is glued flat to the substrate and is the logical choice over existing tiles. SPC clicks together, is thicker and stiffer, and keeps the pattern continuous across several boards.
| PVC panel | SPC panel (click system) | |
|---|---|---|
| Format | 280 × 122 cm | 60 × 280 cm, set of 3 |
| Thickness | 3 mm | thicker, stiffer |
| Installation | gluing | clicking, without adhesive |
| Over old tiles | ideal | needs a flat substrate |
| Pattern | per panel | continuous across the set |
| Price | from €49 per panel | from €179 per set |
For a renovation where the tiles stay on the wall, almost all our customers choose PVC. SPC is interesting when you want a continuous marble drawing across a whole wall.
Are plastic bathroom wall panels the same as PVC panels?
Yes. "Plastic wall panels" is the umbrella term and both PVC and SPC panels fall under it. If that is what you are searching for, this is exactly the material you mean.
So the difference is not in the category but in the core of the board, and that difference is in the table above.
How many panels do you need for a bathroom?
One panel is roughly 3.4 m². Divide the area of the walls you want to cover by 3.4 and round up.
For a shower wall alone you usually land on one to two boards. A complete bathroom with four walls runs towards six to eight.
For the adhesive, the packaging states about 2 m² per 600 ml tube, applied evenly with a 3 to 4 mm notched trowel. That is accurate on a flat substrate. In the bathroom above, with crooked walls and boards 2.50 m tall, well over two tubes went in per panel. So order a tube too many rather than too few. And apply the adhesive evenly, not in blobs: air under the board is the most common cause of problems afterwards.
How do you finish an external corner neatly, without a corner profile?
By mitring the boards: you cut both edges at 45 degrees so they fall together seamlessly. You do that with an angle grinder and a mitre adapter normally used for tiles.
In the same bathroom we built a niche under the shower, and that is exactly where you see the difference. A standard corner profile in aluminium or plastic is faster and cheaper, but it is also the first thing that catches your eye — and it instantly undercuts the premium feel of a marble look. A mitre costs more time and demands a steady hand. The result is a corner that looks as if the wall is made of one piece.
What are the downsides of wall panels in the bathroom?
They are not suitable for outdoors, nor for rooms above 60 °C. And because the material is 3 mm thin, a panel takes on the shape of your substrate — a bulging wall stays bulging.
Beyond that: you cannot go at them with abrasive cleaner. A soft cloth and a mild detergent are enough, and that is the point. If you would rather have a wall that can take aggressive cleaners, stay with ceramics. And if you plan to change the entire layout of your bathroom in two years, gluing onto tiles is a less logical choice than clicking.
What does a bathroom with wall panels cost?
Count on roughly €14 per m² in material, plus adhesive and sealant. For a 3 m² shower wall you are looking at one panel at €49 and one tube of adhesive at €9.90.
No tiler on top of that, no skip for rubble and no week without a bathroom. If you would still rather have it done for you, we can arrange that — ask when you order.
