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!

Yes thank you for your thoughts. the room is 2.8 (with window) vs 3.4m. I do find it a bit annoying too as I don't like that you open the door and see straight away into the shower (though I'm certain the door would have a lock). I'm sure they lined the bath up to be with the window as visually that looks better, but then I find the space at the end annoying. I like the alternative drawings (I like three of them lots!) and I had been considering an drop in bath built wall to wall rather than a freestanding but also finding it frustrating to find a really nice supportive bath and there are less drop in baths than freestanding around at the moment which is a bit annoying. Thanks Anna for the picture, that helps as that looks good (though we would have more space at either end, 50cm) and I prefer the look of yours with some space but not as cavenous... I think I might have to have a talk with my husband as we really need to work out what to do!!

I would prefer to keep the WC separate to the Bathroom as you have 3-4 kids? who will get bigger very quickly, having a powder room downstairs won't help with the morning rush to school., But it's your house so I have added a pocket door between the WC and Bathroom. I have also taken that small robe space for an extra vanity in the WC/Powder room. No width dimesion given for the WC The ensuite could use that extra entrance space as a sit down makeup and hair bench for your wife.

OKL stated what others were thinking that this was a possible student challenge which does happen on Houzz, she's certainly not a Troll, in fact she is known and appreciated for her constant amazing level of informed contributions Your question included " laundry sink + laundry mirror + toilet in the laundry = ??? (All of the above are located in the laundry) " No machines mentioned " Toilet + Vanity + Mirror = 1/2 bathroom." We don't use the term 1/2 bath in Australia, it's usually called a Powder Room which can have up to 3 elements, WC, Vanity and sometimes a shower Primary Bath = Ensuite, usually up to 4 elements WC, Shower, Bath and vanity Happy to help if you need any further understanding of the local terminology
