I would be really bothered to sit right next to the door in the WC, always with the feeling of almost hitting it against my knees. It's not comfortable. But if you could do without the door to the dressing room, I don't think it's bad at all. Then the toilet could even be moved a bit further up according to the plan. I find the solution for the laundry reasonable, enough space for it and separated from the rest, if everything is supposed to be in one room after all.
