Of course the woman in question may now be more infirm than when handles were fitted in her other home earlier or have a different design of bath!

Far too many unknowns to come to any decision re appropiateness or otherwise of the aide.

Myself I would tend to trust the 'expert's' decision (which did not seem to be based on cost but on her training as an OT) but, if I was prepared to take the risk with someone else's safety, fit one myself - they are readily available.

This version is not cheap but readily fitted to most baths is adjustable in height and being screwed to the floor is also very sturdy.
