Fkone – as you’re satisfied with everyone’s responses I’m somewhat reluctant to raise this related issue, but….
Before you and others renovate bathrooms or indeed any other areas of your Units, you must advise your Owners Corporation about precisely what you’re proposing to do, and seek its written consent to that.
Just one of the consequences of not doing so is that if an area such as a bathroom wall or floor is again damaged by an occurrence such as ground movement, the Owners Corporation need only make or pay for repairs to a standard equivalent to what was there before the renovations.
If you think about it that’s fair, if for example the original tiles that cost say $1ea may have been replaced by a cashed-up owner with ones costing $50ea, then the Owners Corporation shouldn’t be responsible for matching owners’ extravagance.
