Hi all, I am really new here. Just bought a resale flat, very old flat which is around 36 yrs old. The toilet is seperated as WC and shower, and each is very small space. Just wondering if the wall in between is hackable? According to the floor plan, it can be hacked. But a lot pipes lay in front and back, which is not gathered at one place at corner. Any one got experience? Thanks a lot ya!
