Got a leak behind the bath which has a shower and glass screen.

I've had several goes at re-sealing around the bath with various silicon sealants.

Today I got a bit carried away and took the whole lot out, shower screen, bath and half the tiles.

The bath was fixed to the wall with 2 brackets which I've fubared as I couldn't reach under the bath to unscrew them from the bath.

I'm planning to PVA seal all walls and the floor, re-tile with a layer below the bath around the shower area and refix the bath.

So - what's the easiest way to secure the bath along the wall? I quite fancy screwing 2x4 batons at either side where there's just about enough room to reach the back wall. Then cross bolting with more 2x4.

Anyone any better suggestions?

Thanks for all the info. - very helpful.

Hadn't thought about tanking but I quite fancy never having to do this again so it's probably worth doing.

I was planning to tile below the level of the bath so that I could then silicone seal between the bath and tile surfaces. Most of the water leak before was at the silicone to plasterboard junction.

Can you tile below a bath and seal to it or will movement just pull the tiles off? I'd always assumed that builders didn't bother tiling below a bath as it was easier to fix the bath to the wall and then tile the wall up from the bath.

The seal was to the edge of the tiles but the gap was quite large and SWMBO likes a bit of hard scrubbing when mould appears. That eventually caused a break in the seal in several places.

That's why I want to tile below the bath so I can make the gap smaller and increase the tile to seal contact area.

Oooooooo I'm getting all confused now.

Tiling below bath - bad idea as it won't be flat.

Water-proofing using PVA - bad as the tiles may fall off if damp gets under them (anyone confirm this?).

Tanking using a water-proofing paste - good but will need to skim the plasterboard to allow room for the layer.

Anything else to consider?
