This is just a recommendation: If you plan to put your bed on the wall adjacent to the bathroom and if the plumbing is all on that wall, you may want to increase the insulation inside that wall so the noise of the sinks and toilet won't wake you up.
There is a bit more information, I would like to add to the floor plans above:
- My software is drawing walls 4 in. thick and a standard wall is 4 1/2 ".
- I should have reserved 24 in. deep for the rod in the closet, not 20 in. This would make the space to move between the rods 8 in. narrower. It would also reduce the rod length by 8 in.
- I put windows 2'-8". I don't know if you have a flexibility on the width of the windows.
In the plan below, I drew the walls 4 1/2 in. thick. I also shortened the vanity by 6 in. to increase the width of the toilet area. This makes the walk to the toilet look less of a corridor.
