You could do a wet room on the south end of the room with the tub and shower combined to conserve space. Window would go above tub, however with privacy in mind it would not be low as you have in your cad drawing. see photo. Vanities would go on the west wall with toilet on the east wall. I am guessing at the dimensions because you mention meters and in the US we use feet, but it sounds like about 9'x15" ? The location of the entry door really impacts the layout of the room, but it looks like it cannot be moved.

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.

This thread deserved more attention. The layout was pretty good too! dart, pest spraying service

I love three in ones because if one bulb explodes, you've usually got a fair few backups before you have to completely fix the bulb (but that's just the laziness in me coming out). In my opinion, I don't think you need a demisting mirror because that's what the fan is for in the three in one.
