Bathroom advice for new build

[Arnold9801]

I’ve just completed the upstairs stud-partitioning for our new build. I’m going to line them with 18mm OSB before plaster boards.

 

Can anyone advise me on whether I need to line the walls with waterproof chipboard which I’ve put down for the flooring for the whole of upstairs as opposed to the OSB?

 

Also do I need a different plasterboard for the bathroom and en-suite and do the shower walls get lined with something else that I’m unaware of?

 

Any advice would be appreciated.

Gypsum backer board outperforms most boards for shower rooms 

and is much easier to work with than cement board 

As a tiler I would use standard moister plasterboard in all wet areas 

Even wet rooms that are being tanked 

If water penetrates the tanking membrane It really doesn’t matter what is under there
