Shower doors

[RoyalAlbertHallSinger]

We are refurbishing our en suite and want to add a bidet. The only way this will be possible is to have doors to the shower enclosure that fold back to the wall, thus, when sitting on the bidet, allowing the shower side knee to project into empty space over the shower tray! I've looked at trifold doors but they only seem to go up to 1200mm and the shower tray will be 1300mm wide. Any suggestions please?

If the space is so tight (regarding the shower door and leg room) have you considered replacing your existing toilet with a toilet/bidet combination in order to free up some space? Something like this:

The only folding 1300 mm shower doors that I have seen don't fold back fully. There is always a panel that doesn't move. Like this one where the panel to the left is fixed:
