New bathroom install - stud wall question

[sam_b]

Been silently surfing in the background for a few days before signing up to get a few folks thoughts on a new bathroom I'm putting in.


I'll be building some new sections of stud wall for a shower cubicle (1100 x 900 - 1 existing brick/skimmed wall and the other 2 new stud sections). I'll be using shower panels inside the enclosure instead of tiling for ease of maintenance etc, probably with classi seal around bottom join.

Any suggestions as to the best product to use for the new stud wall sections:

Plasterboard (skimmed/unskimmed/tanked?)
Marine ply (tanked?)
Aquapanel (tanked?)
No more ply - believe it's waterproof from what I gather.

The floor's currently chipboard.... not my doing..... so I'm planning on taking it up and replacing with 18mm ply.

If tanking is the preferred option is there a particular one recommended, membrane v paint on? I see a sticky in one of the other forums mentioning the Mapei Shower Waterproofing Kit?


Thanks in advance,
Sam

Just an update after I emailed Knauf to check the waterproof properties of AqualPanel:

"[FONT=&quot]Aquapanel is not a waterproof product. Aquapanel is made from Portland Cement and is very porous. Water can pass through the panel but it will not be affected by water ingress"


[/FONT]I guess it's on with the tanking kit over the whole lot.[FONT=&quot]

As you say Knauff Aquapanel is not waterproof but it doesnt break down or expand when wet.

It is designed only for stud walls as any moisture that passes through it can then disipate in the void.


It only comes in 1200mmx900mm sizes and you have to use the dedicated aquapanel screws (ceramic coated I think)

You then either leave a small gap betwen boards to fill with aqaupanel jointing Silicon or with jointing tape and addy.

Hope this helps.

Go for marmox or wedi board if you want waterproof thermal boards or just tank plasterboard with Bal Wp1 or homelux matting.
