Tanking large shower.

[RickyLee53]

Hello,

I am about to install my new shower tray. It is a large type, 1800mm x 1000mm. I need to replace my floor for marine play and bed on cement. This part I'm ok with.

However. The walls, (fresh plastered over green plasterboards) I'm not so sure of.

We will probably decide on a natural tile. What is the best way to tank it? I've seen Bal WP1. But i'm unsure on what to do when installing the tray. I.e. Do I tank past the tray. So it needs to be done now, or just tank upto the tray.

Do I need to have the tray tight upto the wall, or leave a gap for silicone. Do I silicone it first.

I'm open to any idea's. I don't want this to leak and don't have a budget as such. Just the cheapest way to do the job correctly. Even if it means removing what is already done.

Thanks for any help.

Fit the tray tight or even cut into the walls if needed. Seal around the tray. Tank walls and just overlap the tray no more than the thickness of the tile being used.
Tile walls and silicone seal corners and around tray and tiles.

Ok, thats sounds logical, I'll cut into the plasterboard so I get a decent overlap.

Try and cut it as tight as possible. You will need some tape for joints and corners. Mapei tape is good as it is elasticated in the centre. But its what is available to you.

Fresh plastered walls, and possibly a natural stone tile??

double check re tile weights when you do decide on the tile.
You mentioned you're not too bothered about removing work already done - this might be needed if you do go for a heavy stone, if so, have a butchers at another type of board - marmox/wedi/hardie etc....

LOL... Go for a stone look alike ceramic etc .. you cannot put stone on skimmed walls.. at least martyn picked it up..

Hmmm, something to think about. I'm guessing this is the same for all the walls? Looks like we might have to change tile.

Hello,

I'm looking to get this kit. I've heard its a decent brand and looks the easiest place to order from.

Do I need anything else? I'm hoping this will contain everything. And should be enough to tank upto around 1400mm wall height.
