@clare61,
Yes, various means are at hand including broom,mop and slave.
Don't turn around and say you meant hairline fractures in the tiles. I used a two part epoxy resin to paint the tiles black and installed two mirrors along the length of the longest walls. The effect is stunning and very spooky which somehow seems to suit my usual ablutions demeanour. The next project is to knock out the inner brick cavity on the far wall opposite the door and instal an aquarium because we all like to eat fish.
