I'm trying to disconnect the shower tray from the drainage pipe but the white plastic bit that looks like it could be screwed off seems stuck tight:

I'm not sure I can apply the torque needed to unscrew it both because of how stuck it seems and also because there isn't a lot of room to work with:

Out of interest here is what the drainage hole looks like on the shower tray:

And here is the whole shower tray:

Overall my goal is to lift out the shower tray and this is the only thing stopping me from doing that. I will be putting the shower tray back in and will need to reconnect it again afterwards.

Should I cut through the brown pipe at the point where the white screw on bit currently sits and then get a new connector? What tool should I use for this? What part would I need to reconnect it?

Or is there a tool that someone would recommend to apply the torque needed in such a tiny space?

All advice welcome.

    Maybe this would require a basin wrench?

I have used a strap-wrench to undo that type of connector.

In your case there is very limited access but it would be worth an attempt.

It can be difficult if some people have previously applied a sealant - which are not normally needed as there is usually a rubber gasket.


Google for "Bathtub drain key", it's a tool that expands to fit and grip the drain very strongly, so it can be unscrewed from the top.

  • I once made one by pushing polymorph slightly into the top of a shower waste's grating - it worked very well. Commented Jan 7, 2015 at 15:01
