OK, thanks for that. I suppose what I also need to know is how long I
can expect this to continue for? There's no point in my doing a full
repair job on the shower if it's yet to get significantly worse.

It is normal Tony. Most new builds move and settle for years after the main
build completion. I live in a tenement that's over one hundred years old,
and it's still moving slightly here and there. The difference in
temperatures inside and out can also create shrinking and expanding of the
building, so if the timbers were installed in summer hot weather they will
shrink slightly in the colder winter months. It's a natural process for
everything and everybody. If the building were moving by huge centimetre
amounts at a time, then you start to worry, but a few millimetres here and
there is natural.

The shower should have a base seal which allows for millimetre movement at
any time. The weight of a body in the shower will cause the base to move
anytime it's used, and this should always be allowed for in the type of
sealant used. A skirting should always allow for movement against the floor
to stop it forcing when the temperatures change in and around the house, so
this to should be allowed for when fitted.

Believe me, it's nothing to worry about unless the movement is huge amounts
at a time.
