GB submitted this idea :
There seem to be a number of sealing system between the tiles and the rim of
the bath. Which are good? I have two to do - one already tiled and one
without any tiles.

For the tiled area, you can buy a roll of plastic strip 1.5" wide,
which is hinged down the centre (0.75" per surface). On the back is a
soft thick sealant. These work well if the surfaces are clean and if
they are applied by applying pressure with a roller to squeeze the
sealant tightly onto place.
