Going over existing bathroom floor

Gday everyone,

I’ve got an investment property in West Footscray. It’s an very old weatherboard house that isn’t heritage and on a decent sized block.

I stay on top of the maintenance because I just want to keep the thing standing and leased out for as long as possible.

The bathroom is very old and has some weird vinyl it some other floor. I don’t even know what it is. It’s floorboards throughout the rest of the house.

It looks like the floor covering has shifting from the sides.

Any recommendations on what I could lay over it and seal around the sides? Or would I be best pulling it up and redoing it with something else?

I want to avoid having to do the whole bathroom.

Looks like water damage. Best practice would be to take down the whole area wall covering and floor. May be worse and spread more than you think.
Pull up vinyl (looks like vinyl) smell and look for damage. Replace patch up damaged area - Quick fix. If mold is about it’s no good to patch over it as it will not last and will return.
