What sheet material to replace plaster, to prepare for tiling bathrom?

On the stud partition wall, make sure you put 2 or 3 cross braces, flush with the front of the studs. Because of price, just do what the big house builders do, put plasterboard on.

If you miss the cross bracing off (noggings) when you tile, the boards can dip between the studs and you will see a waved effect looking down the wall.

Dot and dab the brick wall and put plasterboard on. Don't need to PVA the boards but upto you.

If tiled and sealed correctly, standard board should do.

I have done several tiling projects now and believe the best solution would be hardi-backer(cement backer board). It is available at your local Lowes or Home Depot. It comes in 1/2" and 1/4". I would use 1/4" where you can get away with it and 1/2" on the stud wall. This will help keep costs down while giving you a solid, rigid base to tile on. Also, the hardi-backer has a grid imprinted on it, helps for laying things out. You will need a cement board scorer also in order to "cut" the cement board. That is around $5.00.

Assuming your in the UK use moisture resistant plasterboard. Nail to the timber studs. If your tiling the full wall there is no need to skim coat. On the brick/block walls screw timber studs to the wall and nail the board as above. Plasterboard of this type should be available from any good builders merchant (jewson, travis perkins, wickes etc)

Recommended for wet areas is green board, you may call it something else. It is a concrete base type of backing. Dimensions are similar to dry wall. This is the best to use. This is seen in tiled showers. Fair priced at local home improvement stores.

you may take all the tile of the wall and eliminate it and do all the demo artwork, which will keep some money. i individually do no longer in basic terms like the pre-fab fashions because of fact maximum of them are fantastically flimsy and till they're put in top they leak, which does you no solid. I even have carried out hundreds of lavatory remodels and that i've got come to do maximum of them with cultured marble. they're good bases so as that they do no longer cut up like the pre-fabbed showers. There are no grout strains to bathe. the aspects are custom poured so if the partitions are no longer plumb or sguare it is not an argument. it extremely is sweet panel, in basic terms the corners are sealed. they might mixture and swirl colours to examine any bathing room decor. And it cost with reference to the comparable, in line with danger in basic terms a touch mroe than a tile bathe. in case you will spend the money for a tile bathe, then surely inspect cultured marble. suited of success.

Just use 12mm plasterboard skim if needed if not mix some pva glue with water brush on to pboard to bond and save money then adhere to that. Good Luck.

cement backer board. Usually 10 dollars or less for 5x 8 ft panel

There is only one answer to your question, Aquapanel. Don't use plasterboard, water WILL get through, somewhere, some time and you will regret it.

Cement backerboard, or "green" sheetrock - for high moisture areas.

Plasterboard laid on dabs then skimmed
