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.
The swinging hinge you show is nice, but can't be frameless. Frameless would look neater, considering the dimension of your shower enclosure / ensuite bathroom

No clue where to buy them not trade though.
