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.

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

Wow, you must have a big bathroom to fit all of that luxe stuff in! Most 1950s houses have very compact bathrooms with tiny showers, minimal vanity and small baths. A double vanity, a walk-in-shower and a free-standing bath all take up a lot more room than what is normally allowed for in a 1950's bathroom so I hope you have it carefully planned. These items often look luxe as they are in bigger bathrooms and the space around them actually contributes to the luxe look. Trying to squeeze these items into a small room doesn't look luxe, it just looks try-hard. Make sure you allow enough room behind your freestanding bath to swing a mop for cleaning, and that your towel rails are more than 1800mm from your shower rose, unless your new buyer likes soggy towels! 1500mm is adequate for a double vanity, but it depends on the size of each bowl. A pair of smaller bowls will give the illusion of more benchspace. An 1800mm vanity has a better proportion if you have the space. The smallest I have seen is a 1030mm wide one from Ikea, with little benchspace, but I reckon it would feel too crowded with two average sized people using at the same time, so hardly worth while. I know some of my clients prefer to have a single vanity with more benchspace. https://www.ikea.com/au/en/catalog/products/S69185850/ Best of luck with your flip, Dr Retro of Dr Retro House Calls

Why wouldn't you put a decorative tray with decorative items to match under the makeup mirror? Lots of choices and it could include jars for makeup brushes, perfume, etc so it is useful too. You need to make it look deliberate - not an added after thought - or that you could not afford another basin!
