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.

I guess regardless of whether it is a single 1800 (4 door) or 2 x 900mm (2 door) the issue of the doors banging is an issue. but the 2 sinks are at one end so i can't ever imagine doors banging will be an issue really. my main concern is whether 600mm is too big for a single door (and the need to step back out of the way when opening the door)

Hi there Not at all, I liked that your sister had a good idea, but can see where you are coming from. Bunnings has had a fairly recent addition to their bathroom vanities, lovely wall hung with drawer and gorgeous slim benchtop. You mentioned that there was a cupboard behind the opened bathroom door, could that be updated for linen storage. In this current layout, the shower is run towards the door with the shower and taps on the outside wall, this helps to direct water away from your large sash window. The shower would be narrow across and longer on the left wall. The whole bathroom floor tiled the same and where I have a short wall that could be a glass screen? I have added a 400 wide full height linen cabinet but if you were to use the other cabinet for bathroom storage you could certainly have a longer vanity with either one or two drawers. This with the mirrored shaving cabinets should give you lots of extra space cheers

I was about to say all our handles are the same size, but they’re not. They’re all proportional to the drawer width. A combo of 165 on 440, 230 on 590 & 760, and 355 on 960. I remember I probably drove the cabinetmakers nuts cos I couldn’t make up my mind about what, to them, may have been a such minor issue! Handles! I feel for you/know what it’s like. :-)
