Its quite common in same areas around here to have the stopcock under the
hall floorboards (older houses). Someone asked me to move one t'other day
so they could have laminate flooring in the hall.

Turned the job down because it was an iron pipe with no joins I could see,
in a really inaccessible place. No doubt it could be done, but not a job
for me.

It leads me to think however that it must be a common problem.

Has anyone seen an 'off the shelf' laminate floor access hatch?

I suppose I could build one, but a standard product would be easier.

I can't imagine it would be a go-er, because it would need to be made
from the same material as the laminate itself. Otherwise you'd end up
with something along the lines of:

(not suitable in itself, as that's for a wall).

I've made access hatches in T&G wall boards in bath panels, by planing
off the tongue as appropriate and glueing boards together, and it looked
fine, virtually undetectable. Would be easy to do similar with laminate
flooring I'd have thought, although personally I've never fitted it.
