Bath gap too large for silicon

danrv

Hi
I’m about to fit shower panels over my bath but just need to fill a corner gap with a suitable filler. 
Gap may be something to do with the walls being slightly out but the bath’s mounted on battens and 
secured to the wall. 
It’s about 12mm wide in the corner and 40cm deep (depth of bath edge). 
Any help appreciated.

Plastic foam or bubble wrap stuffed in the gap then silicone over, you just need something to stop the silicone falling down the hole.

I assume you’re tiling the wall? Or a type of panel? This would cover a lot of the gap. If it still remains then you could silicon a piece of trim all the way round

Yes. The CladSeal trim I bought covers it. Just thought I’d try and fill it too.

Assuming it’ll be tiled in which case run a length of silicone bath seal around afterwards

If you mean the corner between tiles and the trim, then IMO this silicone will add nothing besides mould.

Some expanding (bodgers) foam to fill the gap, cut back once dry, then slap some silicone sealant on top. That should stop any water that gets under the trim from running down the wall - Bed the trim on a bead of sealant to make doubly sure.

Don't overthink it, just fill it with sanitary silicon. smooth it level with the bath then when the shower boards are on you wont see it ever.

Expanding foam is not needed for that, thats a common issue I have seen many times as walls are often slightly out
