PVC and other options for bathroom walls?

MichaelR

Hello,

We need to "do up" the walls of an upstairs bathroom. which was a bedroom before, properly.

A builder is offering to put PVC tongue-and-grooved boards on the walls next to the bath. He is saying they are completely waterproof, so we don't have to replace the drywall. (One wall near the bath is a drywall partition, the other is a concrete external cavity wall).

I'd like to know if this is indeed a good option. In particular:

- What's the chance of condensation under the PVC? He is saying it won't hapen if done right, is that true?

- The tongue-and-groove PVC boards for bathrooms that I saw seem hollow? What if one slips while standing in the bath under the shower, and ends up slamming one's elbow against the board - will the board break?

Also, what are (other) good options? He is saying there is a new waterproof board which he called whiteboard and that can be tiled over. He proposed we put it on the floor (and we don't even have to tile it as it is waterproof, we can put lino on), and we could possibly put it on the wall too? Butt I could not google it out, which is strange... I wonder what it really is, and whether, if we du put that on the wall, we have to tear off the drywall and put it in instead. Also - do we have to tile it?

I would not go with panels against the external wall, you will get condensation.

What about going the whole hog and do a wet room
