Shower tiling

[leshill1]

Hello,

I’ve got a leaking shower valve and the leak is behind tiling that fixes onto plasterboard onto brick outer wall.

In order to get to the leak and replace the faulty valve, I’m thinking of cutting out the tiles around the valve so these can be re-used using a multi tool.

My concern is that the plaster board complete with tile will be removed and that the process to replace the plasterboard ready for the tiles to be put back on will leave a weak point that water could penetrate should the tile growing break down over time.

What’s the best way to approach this?

Thanks

No different to any other area where grout could break down.
My shower is tiles on plasterboard and been there 20 ISH years..

Just cut it out and make repairs thinking about it and making solid somehow.
Needs to be done so crack on
