Plasterboard in shower area

arroli

We are renovating small bathroom with shower/wet room area and all old plaster is currently off the walls, back to bare brickwork

Have had a couple of quotes from plasterers...one suggests using "Aquaboard" plasterboard panels (dot & dab) over all walls with a rough skim on top (we intend to tile the whole area)

Would this make a suitable waterproof shower area, worry is that overtime water will eventually seep into the plaster board?

A few choices

You could use aquaboard but i would not skim as this reduces the weight of tiles the board can take

Standard plasterboard is fine if tanked , would use a Homelux or Dura CI tanking membrane bonded to walls . In my opinion this is far superior to waterproof boards and cheaper too!

We paid to have our bathroom retiled and refitted, and I fully expected them to strip the old tiles.
Along they came and stuck plasterboard over the OLD tiles.
Realised that stripping the old tiles not mentioned in the quote, so was lumbered with a job underway.......
So far it has been O.K. (2 years).....but we have mishapen window apertures now, the window frames (UPVC) are now halfway under plasterboard, and a door architrave flush with the tile surface.
Not happy!

No you weren't - if they weren't doing what you expected then you should have stopped them and discussed it.

Then why did you pay them if you were not satisfied and why did you not discuss your concerns with the quality or execution of the work whilst it was going on? If you didn't you gave them permission to carry on the way they were.

Not happy!

Bit late now really. Sorry to say this but no doubt this tale will be used to bash tradesmen round the head and generally rubbish them as a group but the truth is that you are as complicit in this situation as your bodger so beefing about it
now is really not going to help.

if you use aquapanel you can tile direct onto the top of it. no need to skim it first.

and if you use plasterboard you can tile directly onto it as well.

When I retiled our bathroom the old tiles were stuck onto standard plasterboard in the wet area - they'd been there for 10 years and wouldn't move when I tried to get them off.

So even standard plasterboard can survive unprotected as long as the grouting remains sealed. We do only have a standard electric shower though - for heavy use or power showers tanking might be the way to go.

very true. millions of homes have this with no problems at all.
nearly all modern homes since the 70s, ish, are built this way.

Did a similar job in my bathroom last summer, and didn't use pro plasterer as they where quoting crazy prices. I striped the wall back to brick, dot and dabbed some new plasterboard and tiled right on. Grouted with waterproof grout, sealed the tiles with tile sealer once finished - great result and seems waterproof. Had no issues with using shower etc.

We've bought Aquapanel. If for some reason the grout does fail or whatever, the Aquapanel won't fail as its water resistance Will be tiling directly onto Aquapanel
