What is the proper way of sealing around the edge of a bath? The old one we have replaced was very successfully fitted with a white rubbery strip (quadrant in section) bedded onto silicone. This worked leak free for 20 years but I cannot find anywhere that sells it. It is not the same as either the rigid plastic edging or tape that comes on a roll from B&Q etc. this stuff feels more like solid set mastic.
PS the wall isn't perfect so there is no opportunity for the nice 'perfect world' 3mm sealant bead that you might see on a new build....
Any suggestions/ideas?
