Hi,
We have a shower room on the top floor (extension) and there are these 2 holes in the tiles where the radiator is.
We just had a small leak on the ceiling in the bedroom below - we think it's because I didn't close the glass door properly while having a shower.
How can I fill these holes properly, to prevent any future leaks? There's quite a big hole / hollow part under the tile where the pipe goes in.
Any tips much appreciated !!!
