Hello group, we often experienced a musty smell when opening the shower room door, eventually it got worse so I ended up removing the cubicle and tray, the tray looks as though it had been leaking for years and the water was soaked into the floor joist. The joist end was rotten down to about 20mm. I've had the shower out now for over a week but the smell is still strong and the joist still crumbly. If I leave the joist will it dry over time, or do I need to treat it before I refit a new shower tray, and if so what would you recommend.
Regards Otto
