Tess said… I’m presuming it would only be an Owners Corporation responsibility if the wall was part of common property?
Correct, and as Dave said only if the tiles are the original ones fitted at the time of the building’s construction, because if the bathroom’s been since renovated then everything comprising those works is the current Lot Owner’s responsibility.
Tess said… water leaking from shower recess through wall into bedroom in same unit.
This is the Lot Owner’s responsibility, and before someone picks it up, there are a couple of provisos here that I’ve not discussed because they’re uncommon, and would only serve to confuse at this stage.
So that’s the letter-of-the-law approach, but it seems to me that as your Owners Corporation (O/C) has in the past accepted responsibility for similar leakage problems, perhaps it could do the same with this one by offering to share the costs with the Owner concerned; only once though and on the record lest your O/C sets a long-term precedent
