Hi everyone
A newbie here, needing some professional advice please!
We have a shower that was installed in an upstairs bathroom about 8 years ago. It's all been fine until now, but we are finding that the white grout around a few of our mosaic tiles is turning brown about 10-12 hours after we shower, ie as it dries out. As soon as it gets wet again it goes back to white.
The affected patch is on a partition stud wall and is half way up. It's below the hose inlet for the hand held shower attachment but not directly below - probably a couple of inches to one side.
We've scrubbed using bleach, cif, limescale remover and mould remover (on separate occasions, not together!), and as soon as the grout gets wet it's white again, but the discolouration still returns.
It's been like this for the last couple of months. We wondered initially whether there could be a leak behind the wall but the patch is half way up the wall, so you would think that any water would run down and that the tiles below would also be affected. Nor is any water coming through the ceiling. We've also put a tissue against the grout but there's no obvious sign of damp.
3 photos added, one showing the overall position in the shower, one a close up of the marks when dry and the third showing how they clear when wet.
Any suggestions as to the next step would be greatly appreciated!
Thanks
Chris
