I had exactly this problem last year but after looking at lots of them I decided they just weren't for me.
Instead I bought a tiny curved basin which allowed more door-opening. It has a 25cm projection into the room so we can open the door wide enough. Then we bought the "shortest" wc I could find.
Again, look for one with a short "projection".
My downstairs loo is the old back door "lobby" of a terraced house so very small... less than a metre wide and only 1.4m long. It works.
Good luck!
Anyone else struggle with this?
