Compact door soluition

[jpq]

Hi there,

I'm looking for a compact door solution.
In short I have a very small space in a shop within which needs to go a toilet and sink. I also need a door seperating the toilet and sink so the sink can be used for washing hands and cups etc.
I've put together a small drawing (not to scale) to demonstrate.

The blue line shows where I'd like to put the door.

I recall from my childhood that "roller doors" used to be available. Can you still get them? If so, where?

Thanks for your help.

Joe

Bi-fold door may fit. There are concertina doors but I've never seen a decent one.

If you do go for bi-fold door, make sure to fit a timber door stop to cover the centre gap of the door to keep peeping tom out of sight
