Fitting a bath against/under plasterboard.

[sleptwithatradesman]

Hi,

I'll be fitting a bath in a couple of weeks and have a couple of questions.

The bath will be against 1 stud wall and 1 brick wall. I plan on plasterboarding, tanking and tiling these 2 walls.

The brick wall is plastered and I would like to overboard this wall to save the hassle of stripping the plaster, problem is the extra material would lose me a bit of space I can ill afford to lose.

Is it possible to attach the bath to the existing wall then fit the plasterboard on top of the bath edge? Effectively cutting the bath into the wall?

Are there reasons this shouldn't be done?

cheers for any advive!

Watch out fr clearance between tap knob and finished wall. Obvious, but easily forgotten!

Good shout!

It's the long end that's my problem with the brick wall.

I'll talk the missus into the old fashioned place to put the taps!

Is putting the plasterboard on the bath not as daft as it sounds?

My plan would be -

fit the bath to the wall
Dot and dab plastreboard (then screws when dry) resting on the bath edge.
When set, remove bath.
batten below plasterboard, tank & tile.
reseat bath & seal.

Sound ok?

If you must do it, use a cement board rather than plasterboard.

When the plasterboard gets wet, it will fall to pieces.
Cement board will not.

as above and you can tile straight over it try something like aqua panel

Seal around bath before tiling and again after tiling

I read somehwere that aqua panel and the like are not supposed to be dot & dabbed.

That's why I decided to go for normal plasterboard and the tanking.

Is there a Tile backer suitable for Dot & Dabbing?

It's a brick wall and I don't have room to stud it out.

Bad idea?
