I live in London and moved into a new flat a few weeks back. In the corner shower in the bathroom I noticed there was a lot of black mold around the shower tray edging (yuk!), so decided to replace the caulking. It was a bit of a job removing the old caulking as there seemed so much of it! Once it was removed I found that the shower tray butted up nicley against the wall along one side but along the other side there was an ever widening gap between wall and side edge of tray which was almost 1cm at the furthest point (I hope you can visualise it?).
My question is how do I caulk around the gap?... should I just completely fill the gap with caulking (which is what it seems the previous owner did) , or is there another option?
I can't afford a tradesman so have to do the job myself. I would like to do the job properly, making sure the seal around the tray will be water tight and will also look clean and tidy.
Your advice here would be much appreciated!
