Hello everyone,

We are currently in the planning phase of our single-family house and are focusing on the bathroom design at the moment. For the bathtub, we have decided on a built-in tub. Initially, we wanted a freestanding tub, but that turned out to be too costly, and it would have created a very narrow space behind the tub that is difficult to clean. We like the built-in tub because it avoids this disadvantage but still looks visually close to a freestanding tub.

However, we dislike having tiles behind the tub. Therefore, we are looking for alternatives that are not too expensive and, if possible, can be done as DIY work. You can see this in many photos of modern bathrooms, but of course, you don’t get any information about durability and robustness.

The back wall behind the tub is planned to be built about 35 cm (14 inches) higher than the tub edge. The fixtures are meant to be installed on this back wall. That is the plan so far…

From my research and various discussions, a combination of lime-cement plaster on this wall, with a coating of elephant skin or latex paint in the splash water area, seems suitable because it is cost-effective and looks nice. Possibly, I would only paint the area directly above the tub in this way, leaving the rest of the wall breathable.

Has anyone had experience with this combination? Is it sufficiently water-resistant? Or would you rather advise against it entirely or recommend another plaster/paint combination? What alternatives would you suggest?

I would be very grateful for any advice.

Best regards

Glass printed with a design you like? And somehow color-match the cutout for the fixtures? We are currently considering these options for our showers as well as for our bathtub.

You can do that if you don’t splash or shower a lot. The joint just needs to be executed very cleanly and you must ensure it stays intact. Then not much can go wrong. You can also paint with mineral paint, for example from Keim. It is water-resistant.

Thank you for the feedback.

Glass is also not really our preference. We have deliberately planned a shower niche large enough to avoid having a glass door there.

We don't usually shower in the bathtub. We haven't done any splashing around so far, but that might change with children.

Just for your information, as it might be relevant regarding moisture: we will be installing a ventilation system.

That won’t help you if you splash 5 liters (1.3 gallons) of water against your wall 😉

For a back wall, you can use the following materials:
- Tiles
- Glass or similar full-surface panels
- Elephant skin/latex paint (I find it really ugly for a stylish bathroom...)
- Waterproof plasters/surface finishes like Beton Ciré or similar
- Lime plaster treated with olive oil soap or matte wax from stone oil
- Tadelakt

Can a "standard" polished lime plaster be treated like this, or does the plaster need to be processed differently from the start?
For example, I have only heard of olive oil soap being used with Tadelakt so far.
Are there any particularly recommended suppliers for this?
