Tiling bathroom stud walls

[regorco]

Hi I am refurbishing our bathroom the walls are stud work, i am thinking of cladding them in ply then covering with aqua panel over the bath/Shower area and with plasterboard for the other dryer areas, before tiling. i am using the ply to give a more solid sound proof wall.
Does having a ply surface immediatly behind the aqua panel cause any problems and will using plasterboard in the dry areas be ok.
thanks

If they are stud walls then pack with insulation for soundproofing, something like Celotex or Kingspan to the depth of the studwork, (will help with insulation as well) use aquapanel in the wet areas and moisture resistant plasterboard elsewhere. Make sure you tape and fill any joins in the aquapanel, no need to use their screws though platerboard screws will be fine. No need for plywood, and actually it won't do much for the soundproofing anyway.

What size and type of tiles are you using, and are you tiling the whole room, aquapanel and plasterboard have different characteristics and can hold different weights of tiles. If you are tiling the non wet areas DO NOT get it skimmed, this will reduce the weight of tiles and adhesive the plasterboard can take.

What adhesive and grout are you planning on using?

Thanks for that, the tiles "that we have already bought" are large 600x300 any further pointers appreciated

Do not use ready mix adhesive - you need to use a bagged adhesive that you mix yourself with large tiles.

600x300mm...ok

check the tiles for any "bowing" along the 600mm,lay tiles on a flat surface(worktop)etc and look for any bowing..(slight curve in the tile)..if any bowing..

then dont fix the tiles in a broken bond style(brick affect) you will get lippage over the tile/wall especially in a good light..

if you want to brick effect then instead off 1/2 tile then go for 1/3 in the brick effect,this helps do away with any lippage...but you could still end up with some lippage...

if bad bowing the fix risbond(regimental style)...

ok the tiles..what type are they...ceramic/stone..? do they need sealing..
what colour are they??..light stone,if so use a white rapid setting flexy adhesive(stops any bleeding throught the tile)..
are they porkie tiles...if so, use a porcabond adhesive for them..

grout again flexy..colour,what are you thinking off using...floor stay away from white(gets very dirty over time)..
