In my opinion that's ridicules you can have a wet room in any floor you just need to use the right material.
To paint a dry plaster wall
1.clean all dust and debris off the plaster, and lay down dust sheets to protect the floor
2.the porousness of the wall means you have to seal the surface first. create a sealant by combining four parts water-based paint with water, or by mixing four parts of an oil-based emulsion with a pva adhesive. if you are painting a bathroom or a kitchen, use an oil-based paint or one specially formulated for bathrooms or kitchens. don’t be tempted to skip this step. plaster is so porous that it will suck the moisture out of your paint, causing the paint to dry out and flake off
3.mix the liquid thoroughly.
4.paint this mixture on the walls as you would normally paint a wall. this thinned paint will fill in the pores in the wall, and if you listen closely, you can sometimes hear the wall sucking up the liquid.
5.you can apply another coat when the first is dry if you want, but it is rarely necessary.
6.if you want to paint the plaster before it has fully dried, use a microporous paint, which is designed to have tiny pores that allow the plaster to dry properly. though this paint will cover the look of the plaster, it is usually recommended that you coat the microporous paint with regular emulsion once the plaster has fully dried.
7.paint the wall as usual.
It's best to have your electric shower installed by a part p-certified plumber or electrician, as they'll understand the electrical engineering necessary for such work.
On my experience that is expensive i normaly do 100pounds per piece including fitting materials.
