How much would it cost renovating a 30y/o resale 1100sq ft HDB, anyone has experience?

Hey Anon,

I'm no expert but you can try out this renovation calculator here to get a rough estimate! Hope this helps!

It depends on the quality of tiles that you are changing and the expectation of the toilet refurnishing. It will be better to talk to the contractor directly.

In my opinion, it can cost from $25k to $50k.
