Putting in new en-suite

Removed tiles, sink, shower &* carpet.

some of the chipboard flooring is water damaged. I can remove and replace
most of it, but about 6 inches of board comes under the stud wall. The wall
runs parallel to the joists, roughly halfway between two joists. If I cut
the chipboard back to the wall, the chipboard under the wall will be
unsupported.

Is there any risk of the wall using the chipboard for support?

yes. In most cases it wont but yes it can do sometimes.

If I cut back the board, is there any (easy?) way of getting support under
the wall?

I dont see how one could comment without seeing the job.


Alternatively is there any sealant I can get which will soak into the
chipboard and stabilise it (the water damage in this area is not too bad.)

Interesting. There is wood hardener, I really have no idea if it would
help or not.

Finally - what is the best way of protecting the floor from water damage in
the future (I will be fitting aqualoc laminate flooring with a water proof
underlay - I could try running that up the walls a bit.)

The best approach is to fit a floor that doesn't mind getting wet.
Chipboard is unsuitable for a bathroom. Strips of wood half wrapped
in wet retaining plastic would also seem to be be a poor choice,
especially when those strips are thinner bits glued together, ie
laminate. Concrete and lino or bathroom carpet are much better, and if
you have some ventilation underneath, then lino over wood is normally
fine too.
