This might be a daft question, but I can't see an answer from the
various literature on the web etc TP were pretty clueless too...

Like many, our downstairs toilet is small and I am re-fitting it (loo/
sink/boxing etc). To try and make more room I am toying with the idea
of replacing the standard 30" opening-inwards door with a bi-fold
door. We have some of these on an airing cupboard and they work ok.
They slide in a top rail, and have a floor mount pivot in the
corner.

So all Bi-fold internal doors usually mount in this way?

Can a bi-fold door be mounted on 3 standard hinges on a standard door
frame instead?
I want to avoid having anything in the floor if I can.

Note that it will be the basic bi-fold panel white primed door that
Wickes/B&Q/Magnet etc all sell. It will not be a heavy solid pine
affair.
