No clue where to buy them not trade though.

You want to prefer hinges that open both way, it's not good practice to have a door openning inward only, as if someone collapses while having a shower, you won't be able to help them getting out as they would block the door swing.

Very similar if not identical hinges are available from Hafele. I paid about £50 (trade) for a pair last time I bought some. See my previous post about suppliers or once you have the Hafele code search on-line.
If getting the hinges is a real pain I can order some at trade price but it would have to wait to go on the next workshop order. Their catalogue but not their prices is available on-line

The opening both ways door is a*** very*** good point. Hadn't thought of that.
