Conor Posted September 21, 2021 Share Posted September 21, 2021 Our stud wall company is supplying moisture resistant plasterboard for our bathrooms and wetrooms. We have a large walk in shower in our ES wetroom - is plasterboard OK to tank and tile or would we be better off using backer board for the parts we're tiling?

Temp Posted September 21, 2021 Share Posted September 21, 2021 We went for 12mm Hardi backer board and would do so again in shower areas. Its hard work to install as its so hard and heavy but our builder recommended it and its bomb proof. I've fixed things like soap dishes and into it and they have remained solid for >10 years.

Faz Posted September 21, 2021 Share Posted September 21, 2021 Can't go wrong with hardi backer. However, no-one on mine wanted to use it so up went green board. I used 3 coats of the Everbuild wet room tanking system on all wet areas - simple paint on application. 1 Link to comment Share on other sites More sharing options...
Gone West Posted September 21, 2021 Share Posted September 21, 2021 I also used 12mm Hardie Backer board for our wetroom. It's heavy and a bugger to cut but I think it'll still be there for many years. Link to comment Share on other sites More sharing options...
