stud wall in shower area

[snowsfield]

i need to do a stud wall in the shower area to take a aqulisa thermo control & 4 jets, can anyone advise me on what type of plaster board to use & how thick, it will be tanked & will have to be strong enough to take 600 x 300 porceline tiles
many thanks guys

In shower areas I always prefer to use a tile backer board (Aquapanel or similar) rather than plaster board & especially so with tiles of that size/weight. You won’t need to tank/waterproof it, just tape & seal the joins & tile directly onto it. Use quality trade flexible powdered cement adhesive with tiles of that size & a flexible waterproof grout.

thanks for the info RC, the problem i have is that one wall will be stud & the other is old brick that old tiles on it that was put in the old way onto wet cement & i have hacked them off fewwwwwwwwwwwww was that hard & it was only half way up, the same wall the short side of the shower (900) continues for another 900mm but i have no room to come out with the stud, should i dot dab in MR board or skim the hole wall, hope you understand me,
many thanks

As long as the wall is in reasonable condition & recoverable, I would re-skim it & tile directly over that rather than D&D plasterboard over it.

bit late but you should never tile onto a new skim it need to dry out and that will take weeks - board it

If it's just a re-skim you should be able to tile over it after 10-14 days but a float & skim will need around 4 weeks.

Re-skimming the original block walls is by far & away the best solution if they are in a suitable condition to accept it; if not I would I would still go for a float & skim plaster finish. Boarding over is a “quick fix” but, personally, I would only do it as a last resort. Using the wrong boards or incorrectly fixing & prepping them can lead to so many problems just a few years down the line as anyone involved with renovating bath/shower rooms knows only too well!

i would use 3x2 for the stud wall that should be sufficient for what you need, put extra noggins in to strengthen it all.

when ever i have done my own bathroom work i have always boarded out stud walls and skimmed them and to make the whole thing watertight i have tanked the walls that would be subject to water.

as for the other walls , i would always re float then skim em all.
