In our complex, we had a by law drawn up to ensure owners were responsible for their own internal plumbing and for leaking bathrooms/showers etc. so we not only have to pay for our bathroom repairs but had to make our own arrangements too.
You would still be paying for it if the OC did pay for accommodation for you. It comes out of funds that you have paid into. And if they pay for your accommodation, they would have to pay for everyone in similar situation. So say you have 20 units. Accommodation for two people for two nights in Sydney about $200 per night, $400 per stay. Times twenty is $8,000. Plus cost of bathroom repair. Say repair was $500 per bathroom. You have just about doubled the cost of this repair. So to cover such increased costs you would have to raise the levies and so therefore you are paying, one way or another, for your accommodation, even if you never need it again.
I am looking at getting a bathroom repair done. Only have the one so will be doing the sponge baths and showing up to friends places for dinner with not only a bottle of wine, but towel, soap and bathrobe!
