For those still reading this thread. We just recently completed a bathroom reno in almost identical sized space though turned the other way. A lot of reflection in the photos sorry but there is a lot of glass and mirror. A cavity slider, while an added big expense, made the whole thing possible. To create the space I used the adjoining separate toilet room for the 1200 x 900 shower and shallow tall cabinet on the left and gained a closet in the hall outside with the rest of that corner. I also recessed the towel rail which helped give room to the shower entrance and not stick out in front of the loo. Wall hung vanity and toilet. Porcelain wood planks on floor with underfloor heating and also used in shower base. Excuse the towels, they are not my normal ones ! It was a big decision about joining the rooms and whether to keep the bath / shower but I think it paid off. There is just the two of us and it's a real pleasure to use and no longer feels like "standing room only"

Your mockup scheme is similar to our master bathroom we just completed - photo below. I know you mentioned storage being a concern - our mirrored cabinet has offered an amazing amount of storage in a very small space and also helps bounce light around. I was worried about black taps etc too so we kept chrome fixtures but added in a matte black candle and black potted orchid to create a similar effect which we can change out later on. Our floor tiles are dark but because they are semi-polished they actually bounce around a lot of light and don't make the room feel dark if that is a concern. We also have a huge fiddle leaf fig in the corner (not pictured) which adds a really nice feel to the space - a plant like that could help bring in the outside greenery in your bathroom. Instead of the storage tower you have to the left of the vanity could you do say some floating wood shelving, possibly with baskets added for more hidden storage? You could also bring in the 60s theme with what you displayed on there eg. photos as you mentioned? In regards to the window - a previous house we lived in had a window at about shoulder height in the shower - as well as letting in heaps of light it was amazing for storing toiletries etc!

As a suggestion, could put a free standing bath where the toilet is located. Then shower and toilet behind a wall with vanity in front... In the ensuite, put the vanity where the shower is and have a walk in shower. Howeer, you may need to relocate door.

Thanks oklouise. I love your ideas and the ensuite layout is great. However, I don't think I made my dimensions clear enough and I don't think the rest of your design can work Bed 1 - 3600 X 3600 Bed 2 - 3700 X 3000 Current bathroom - 1960 X 2600 Current laundry - 1820 X 2600 Current toilet - 1340 X 1100 So if we keep the current bed 1 and bathroom space and convert that bathroom to the ensuite, that leaves approx 3200 X 2600 for the bathroom/toilet/laundry. Ideally we would leave the current windows ( a 1000x1100mm sash window 1200mm from the floor in the laundry area) and a high (550x700mm window in the toilet area) which makes juggling the space a bit challenging. Thanks so much for your help with this!
