We’re planning a bathroom reno in Adelaide and are keen to eliminate mould accumulating grout lines.

We are considering acrylic/polymer panels (like ISPS Innovations' Bonethane or IPA Acrylic) for our shower walls instead of traditionsl wall tiling.

Plan would be to remove all the old tiles and replace the cement sheeting, prepare the walls with a waterproof membrane and then have a professional install the panels directly to the prepared surface.

Has anyone here used this method for a shower area?

How’s the durability and maintenance over time, especially in a wet environment?

Any challenges with adhesion or long-term wear?

Would you recommend this over traditional wall tiling in a wet area?

Would love to hear from anyone who’s had this done, especially if you’re in Adelaide or can recommend local installers who specialize in this type of installation.

My fiancée and I are looking at redoing our bathroom as a wedding gift to ourselves. While my soon to be better half is set on a bath fitter, I think I've talked her off the proverbial ledge - she does have one point though: Acrylic Shower walls are much easier to deal with.

Has anyone installed these over a standard cast iron alcove? Are they worth it? Or do they feel cheap? If they're not worth it, what's a good alternative to tile and grout?
