i wonder if one of the round shower screens would give better access

and consider an off the floor wall hung vanity, mirror doored wall cabinet and smallest toilet (allowing at least 800 width for toilet space and 900- 1000 width for shower) would all help improve feeling of spaciousness

Thanks @oklouise, looks like we are both on the same page. 👷‍♀️

Would you consider gaining extra space by doing the following

Hi Ann,

I believe your best bet would be to go to a shower screen installer for something like this. I've seen similar bi-fold systems off the shelf for use onto bathtubs, but not for a shower area. Also consider with this system there will likely be some water coming out into your bathroom as the shower panels do not reach the ground and photo you attached doesn't have any system for stopping water.

Thanks @ArvCorp, the floor has a reasonable slope. I will see that the screen guy says. Thanks for your input.
