Work progresses on Bungalow Barn, all the partition walls are in as studs and we are starting first fix plumbing. I am planning materials for next stages.
We intended to board out the bathroom with marine plywood so we could tile directly to that and it would cope with humid environment. Then I went to a local reputable tile shop on a reccy and they said that marine plywood isn't what it once was, the quality has gone down and now they recommend using tile backer board. I hadn't heard of this before, the sample was foam with very slim concrete (?) skin either side kept stable by mesh.
The tile shop weren't trying to sell it and they have a very good reputation for advice... but I am just not sure of the pro's and con's and so I'm here wondering if anyone has experience with either or both that could help me decide which to use... Thanks
