How to fix timber rot in shower base?

IMG_5035.jpeg

Hi all,

 

I’m in the middle of an ensuite renovation and the shower walls are currently stripped back to the timber framing. At the base of one shower wall (where the studs meet the slab), there’s visible timber rot and moisture damage from the previous shower.

 

Before the walls are re-sheeted and waterproofed, I wanted to get some general advice:

 

  • Is it acceptable practice to waterproof and tile over timber that shows rot or degradation at the base?
  • In a situation like this, would you normally repair or replace the affected timber first?
  • What’s generally considered a reasonable fix (e.g. treating and leaving it, sistering a new stud, partial replacement)?

 

 

I’m not looking to over-engineer things — just want to make sure the structure is sound before it gets sealed up permanently.

 

Thanks in advance for any insight.
