Thanks for this! Pretty sure that the previous owner had some water damage because they painted some spots on the ceiling below the bathroom smh. My biggest concern is how much damage did it have.The walls should be tear down to its every square inch, for you to see if there are any probable leakage of some sort or even termite issues. I suggest use drywall, compared to its peers, it is cheap and worth it!
I also wanted to my bathroom to look modern. Did you have any troubles coordinating your design to your contractor?I felt like a fashion architect when I was designing our bathroom, I went bold and didn’t think of other people’s say about it, and it went splendid! I designed it black and white with gold brushed finish.
My suggestion is to design it ahead on time so you can conduct a proper plan of the whole bathroom accordingly.
