Damp found under bath

Howitzer

Hi,

I was wood panelling the bath last night and found damp soggy plasterboard on the wall. There is polythene behind this (damp to touch) and pvc water pipes at ground level.

Looks like I'm going to have to rip the bath out to investigate.

Should I get a specialist in for this job?

Cheers

Are the floorboards affected?

It could just be the silicone sealant at the edge of the bath needs to be replaced. Leave it alone for a few days (not using the bath) and see if it dries out - a small fan might help shift air in behind the bath to dry it

The plastic bath siding has been off for the day - and it seems a bit dryer in there.

It's a concrete floor beneath. No damp on the floor.
One wooden batten of the bath support it brown with damp.
Maybe its not a major job. Will leave it to air and then see.

All bath sealant is new and looks in tact.

(Just moved into this house btw - so finding little surprises like this is part of the deal!)

As Borzoi said

or any bath trims.
They look OK when the bath is empty but you should have a look when you are having a bath ( or shower if their is a shower over the bath ). Depending on how well the bath is supported it may sag slightly with the weight of water and a body in it.

Or fill the bath with water and have a look. You might just see something then.

You should fill the bath with water before putting bath sealant on, helps prevent this problem. Yes I know its a bit late to be telling you this now

good tip! - not too late - will be re-sealing soon anyway.
