Hi,

I've just put in a new plastic bath which seems to be made of lighter
weight plastic than the last one.

When I push/pull at the side of it there is 1mm or maybe 2mm of
movement between the side and the wall.

Will a silicone sealer be ok with this movement? Any particular brand
work well in this situation?

Remember that its only supposed to accommodate movement of about 10% or
15% of the thickness of the bead - so if you are going to have 2mm of
movement you would need a decent sized gap to get a thick bead of
silicone in.

A trick that helps is to fill the bath with water first so that it is at
it's lowest point of movement. Then seal it - let it dry overnight
before emptying the water. That should mean in the "rest" condition the
sealant is under slight compression which is relaxed as you fill the
bath. This will put less strain on the sealant.

The "sanitary" silicones seem to be a little more elastic and also tend
to include fungicides and mould inhibitors:-

Did you batten it along both sides? Makes a hell of a difference to
stability with all plastic baths.

The classic solution is to fill the bath with water before sealing.

I prefer to build up a bit more structure to support the bath as well.

Actually I prefer to buy a decent thickness bath, personally.
