Hi, One option is to eliminate the gap with a nib wall like i have attached. It really depends on the size of the room in terms of how it is structured and what you want to archive. The wall hung vanity is great for smaller rooms but cleaning underneath is hard and you wont really be able to have a nib wall without creating a dust trap. Just thought i would throw out a idea. Good luck with the build

Alright let's see if we can put this to bed. There's nothing at all wrong or amateurish with your home. Agree seeing photo it's arguably too much of a compromise nor cost effective to move/change the window considering outcomes. The solution here will come in the fit-out and how to balance that as best as possible within the constraints set. You can do it with a 1500 size bath option, 900x1200 shower. and it's essentially a tweak/fine-tune from the idea you had originally. (I shouldn't really do this but here you go/I'm feeling generous today ;) ) You run a ledge all the way around the back and end walls. Mirrored cabinets all along the end above the basin. This will feel massive and luxurious with the ledges/more dimension & interest. But you'd need a concealed in wall cistern. Any privacy concerns (in bathrooms) can be managed by combination blinds/furnishings - arguably much more flexible (and cheaper in this situation) than changing glazing to frosted glass. And then you still retain an outlook/light to your ensuite during the day etc... Good luck & Merry Christmas :) PD

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

the measurements look more like a hallway space..challenging but never impossible and any internal room can always be improved with my favourite Solar Skylights (try Illume or Arcol brand available at major hardware stores) but, if you're planning to retile and adding another room there's no better opportunity to see if there's any opportunity to rearrange the space to a more comfortable shape..post a plan including of all the adjoining rooms and the new room
