Stuart Noble explained on 08/09/2005 :
Can't get the hang of this at all. If the bath is rigid at the base, how is
the rim likely to move?

They do all move to some extent due to deflection due to the weight.
Especially on a wooden floor and even more so plastic baths. That is
why you fill them, to put the sealant round, so the deflection is at
maximum.
