Rubbish Plumbing

ok, this photo won't win any awards but I think it demonstrates just how crap a professional plumber can be. It's the underside of my upstairs shower tray, and it appears to be held together - just about - with silicone sealant. Honestly, my pet gerbil could have made a better job of it.  Anyhow, it leaks. But not as much as the handbasin tap leaked, almost bringing down the kitchen ceiling, which is why we currently have no kitchen ceiling. Aaaaargh.
