TheScullster coughed up some electrons that declared:



Be aware that baths do expand a bit with hot water in!
I mention this from a tiling/decorating POV.
I made a tiled shelf-type-thing to fill a gap between wall and bath at tap
end, the edge of this "sitting" on top of the bath edge IYSWIM.
The movement of the bath between hot and cold is just enough to disturb
grout .

Thanks for that Phil.

I hadn't considered expansion, but I was worried about flexing. So I'm of a
mind to "grout" the edging strip tiles with silicone which should handle
it.
