Well you posted this several months ago, but I thought I would make suggestions anyway. Hope you don't mind. In order to stay with or keep in mind the style of the shelves I would first change out the towel rack and TP holder to a chrome, or brushed nickel finish. Or get something that goes with the water faucet on the sink. If you are going to paint the wood around the shower base, paint the window trim and pieces of baseboard that are wood as well. I agree with using a gray color that adalisa, above mentioned. Maybe paint your vanity a darker gray, or even a shade of black, like your shelves to tie it in. That's it for me.

Have lived in places with a tiled window -- tile the sides and top as well as the ledge, so that you go right up to the caulk/frame/glass. Works to let out some steam and store shampoo too!

It all depends on what you want to do in your laundry and what in your bathroom I guess. I appreciate the fact that there might not be enough space to do this but I store outdoor shoes in the laundry and the dog's leash and cleaning stuff. I need room to sort the dirty laundry into piles before washing it. I keep the ironing board in there and I need a tub to wash things in and to do flowers in and to put the odd cloth that wiped up the cat sick before it gets rinsed and washed.. heaps of things other than just washing. Couldn't manage with a cupboard laundry ( piles of washing on the hall floor when using it) and think these kinds of laundry functions might not make a gorgeous lavendery bath or shower feel that luxurious. So I am for as big a laundry with tubs, cupboard and bench nearest the outside back entrance and yes washing line as poss. And a lovely fresh warm bathroom near the bedroom separate from the dirty clothes and boots and all that other stuff.

thank you for your comment. we are looking at using the interior wall, opposite the sink, for ceiling height cupboards utilising the wall cavities so as not to crowd the thoroughfare. I will keep a look out for replacement wooden windows. i would like to move them to the left so as to create more space in the corner area for hopefully a fridge? what to do with the fridge?
