Shiplap in bathrooms? Aquaboard or something else?

[Oncemoreuntothebeach]

I love the look of shiplap in bathrooms, something a bit like the images attached. Does anyone know how I would achieve this and keep the room waterproof? Is there any aquaboard that looks like shiplap, or is this a terrible idea and I should just find a way to waterproof the wooden boards? Any advice much appreciated! TIA

There are no images attached, I think. I have seen various composite shiplap for external cladding, which should work in a bathroom, too. If you take reasonable care and ventilate and wipe down spray/spills, water-resistant mdf primed and covered in 2 coats of eggshell/satin paint should be fine, too. You'd tank the walls and floors behind shower anyway with specially sealed backerboard before you apply any wall finishes, which are only cosmetic and don't do the actual waterproofing.

Do you want it right behind the shower, or just on the rest of the walls and as a bath panel? If it is the latter, real wood (oiled or painted) or mdf is nicer than plastic. The English Panelling Company makes lovely t&g sheets that you could fix horizontally for a shiplap look, and painted they hold up well in bathrooms.

Oh how strange, let me try uploading them again...

Ok, this seems to be working better!

This is the dilemma I'm having! I'd prefer real wood too, but its such a small room I wonder if it would be better to stick to just one wall finish.

Had shiplap panelling in our bathroom for about 20 years. It's mdf painted with eggshell. Bath panel is also shiplap. We freshen it up every few years with a new coat of paint.

Look up timbertect, truly miraculous stuff

We have it on a log cabin and wooden counter tops and it's amazing water does not get it. No stains round the sink, leave a damp cloth all night and no bother. If you treat wood with that you can put panels where you like.

@someoneseatenmyapple that's good to know you've had it in your bathroom for so long with no issues.
@DogDaysNeverEnd wow, I've never heard of timberect, sounds like fabulous stuff!
