Hi, We are having tiles put over plywood where the hidden cistern is located. At the moment there are different pieces of plywood which make up the front of this boxing, please see the photo. I was wondering if it is better to have the plywood in one piece without the joins? or will it make no difference to the tiling? The new tiles are 300mm by 600mm.
From the picture above I can tell someone likes jigsaws ..................(not the power tool variety).................. Unless there's plenty of studs behind that ply, especially where the joins are, and plenty of fixings, there may be some flex in the board (ok, its behind the loo so not subject to much banging about) Any substantial flex will loosen tiles over time Do a nice, proper job, gives you more confidence that it will last. Remove the mish mash of ply, reboard either using a cement board (as above) or considering its not a particularly wet area - would have thought 12.5mm PB will do the job - again with studs for support
Plasterboard board wouldn't last long, especially if in contact with floor, would soon soak up any mositure if there was any break between sealant floor & wall tiles. Cement board is totally impervious to moisture & water, most have a anti-mould coating to prevent mould developing in unseen places, something which is quite common with plasterboard.
Great replies! Thank you for the ideas. Will look to change it as suggested. I do want it to last as long as possible and seeing the pieces as they are did not fill me with confidence that it will last.
