Usually I use Aquapanel and then tank the walls inside shower areas before tiling which is probably overkill. I've got a client who want is done on a bit of a budget so would MR plasterboard and then tanking be OK before the tiles?

I'm sure Royal Oak has given his opinion on this subject more than once..provided the workmanship/tiling is sound then it'll be fine..infact I know of one job (Done by myself some time ago) where the plasterboard wasn't MR, no tanking, power shower..still sound after 12 odd years..and there is an access panel from the airing cupboard to the pipework to the shower, so you can see it's sound.

If you want to tank, then use normal plasterboards.

British gypsum have a new board out for shower areas, by the way.

12.5mm plasterboard tanked will be fine.....


at the end off the day...roc...is just a..wood butcher..,he aint no tile fixer....

The very same, mate.

Lafarge also do a gypsum based board which can be left to the elements for 6 months if they are on a frame. Gtec Aquaboard.

Just for peace of mind Mapei Tile Adhesive Primer or similar first (never PVA)

You need to follow adhesive instructions, some situations you need to cross prime......two coats.

The new gypsum board there is no need to prime before tiling.

We are just stripping out a couple of bathrooms in the same flat at the moment and this just goes to show it is workmanship and not necessarily the 'gucci' materials which ensure a job which lasts.

Bathroom one was fully tiled over plaster, over tile, over sand and cement.

Bathroom two was a mixture. Sand and cement, plaster, distemper, emulsion, plaster and tiles all on the one wall. Half height tiling on sand and cement, sand and cement above with distemper, emulsion, plasterboard and then fully tiled to another wall.

Both bathrooms last done about 20 years ago and only being done now due to a flood from upstairs.

The original tiles must be at least 70 years old.
