Hi, did you mean to attach a photo?

My preference for the width of stile and rail is 40mm minimum. I have a cabinet which has 260mm wide doors with 45mm stiles and rails. Any width less than that wouldn't look right especially if the doors are wide. I think it best to size up all the cabinet doors and drawers then do a compromise as to the best fit. Slim drawers are best left plain without the details.

Hi Sue, I think it would look amazing if you used some tiles with a bit of texture. The wood look tiles that are popular at the moment would be an example. If you chose a colour that toned in with your floor you would get a really nice cohesive look but with a bit of interest. I've attached a photo of a recent design of mine as an example. Just a suggestion!

Ideally you would want 900-1000mm clear space in front of your vanity and for walkways, unfortunately we don't live in an ideal world and have to work with what we have. 700mm would be the absolute minimum width for a walkway to still allow reasonable passage, although I would be reluctant to go this tight. A floating vanity will help the space look larger and storage can be included in a mirrored shaving cabinet or mirror with shallow shelf above the vanity.
