Shower Alcove - need 10mm backer board maximum.

[steve1953]

Hi, I've just popped in from the plumbers forum to ask you experts..

I've ripped the remains of the skimmed stud wall plasterboard with tiles over from my shower alcove. It had a 760 tray and a false wall to fit. Without putting another false wall in I can fit a 800 tray in. But that leaves me with only 10mm each side for new boards.

All the backer boards seem to be 12/12.5mm.

I can only think of using 9.5mm plasterboard tanked, but it seems too flimsy to me.

Would ply be the only option or is that a swear word here.

Marmox do a 10mm board mate, the Uheat sponsor on the right sells them

Hi Steve, what tiles are you going to use ?

 

[steve1953]

I thought 300 x 200 ceramic.

If that's all your gonna be fixing ( as in nothing heavier ) and you are gonna tank it, then I would use plasterboard with extra noggins if the present structure is flimsy.

HTH

EDIT: do NOT use ply, no way no how

Thanks Alan,
As I've already got the plasterboard I will follow your advice of the extra noggins and see how it feels. It's not the present structure that's flimsy, I just thought the plasterboard was not up to the job. After I cut it, the edges seems too crumbly. I suppose the tiling will increase it's strength.

Thanks for the responses Alan and Mart

If it's a stud wall then drop your stud legs down to 300mm centres & add dwangs (noggins) & you won't have a problem..
