Or more accurately leaky tap/bath interface.
Under my bath it's a soggy mess. The back nut that holds the hot tap tight to the bath was loose, allowing water when I'm showering to get through the tap mounting hole. It's a grp bath with a ply wood batten spanning the tap holes on the underside of the bath and the back nuts tighten against this. A month or two ago I tightened the nut as best I can but the piece of ply is squidgy and falling apart limiting how tight I can get the nut.
Today's thing to Make and Do is to find another piece of ply, remove the taps, replace the squidgy ply with firm piece of ply, replace taps and tighten up. Presumably there's an o ring/rubber seal on the top side of the bath. I'll probably use some silicone sealant here.
Good idea? Bad idea?
