Tiling on lath and plaster walls

[White Room]

well in the old days you would drill holes at the top every 150mm put a small hose throught the holes atached to a funnel then you would mix unibond with 70% water and pour in then you would go down half way drill holes again and repeat leave three days to dry with the lime plaster and hores hair and lathes it would harden like concarete give wack with hammer to test its strengh then tile

what!!!!!

I thought that whitebeam but didn't want to ask forward explanation.

To the op. Is this over bath. Shower or wetroom. What work are you doing exactly?

Its my full bathroom, tiling the full room (floor to ceiling). In the bathroom, I will be replacing the electric shower (not a stand alone shower but one thats part of the bath), toilet, actual bath and also the basin.
Also installing a towel radiator.

The walls are 20m2 and the floor is roughly 5m2

Anyone help?

So if i strip out the wooden laths (and plaster first of course), then attach plasterboard to the studs- what sort of weight with this then be able to hold? (will it then support the 60x30 tiles i want?)

Also- would you advise to get the walls skimmed as the walls won't necessarily be square/level for putting the tiles on?

Also would i use the moisture resistant gyproc?

You'll get 32kg per metre on plasterboard which will be ok for 600x300 which could be 23/25kg. + adhesive and grout. DON'T get them skimmed! Moisture resistant plasterboard would be ok, but cement boards or waterproof Wedi would be better but more expensive.
Good luck.

With old properties the stud wall timber might not be the same size..and a little twisted as the lathes and plaster wwere'nt always nice and flat, more of a wave to it..if your using 600x300 then the new board will need to be nice and flat..run a long straight edge horizontally to the vertical studs to see how far if any, are out, you may need to pack them out..get the substrate sorted first, this will make laying the tiles a breeze..unless they're are bowed !

Well i started hammering out the plaster and something just didnt feel right. Something was worrying me. I wanted to check there is zero possibility of asbestos in the plaster, as my house was built circa 1935.

So i have sent abit of the plaster away for testing. Once i get it back (hopefully clear), I can continue taking the lath and plaster completely out. The studs looks solid anyway.

Yep i know about not getting it skimmed as the weight capacity drops to 20kg/m2

Thanks for everyone's input.
