We converted a 5’ x 8’ closet into a small master bathroom. Shower, vanity and toilet. Did one of those single wall curb-less, door-less showers in there. Super happy with how it turned out. https://sayyes.com/2020/04/new-master-bathroom-tour More on reddit.com

Trust me. Buy this vanity. http://www.homedepot.com/p/Glacier-Bay-Del-Mar-30-in-W-x-19-in-D-Bath-Vanity-in-White-with-AB-Engineered-Composite-Vanity-Top-DMSD30P2COM-W/100672710 I have the 36" version. its the most spatially efficient vanity I've ever seen. Only 12" at the cabinets and flares to 18" at the bowl. I think you will regret filling that whole room up with cabinets. I support the in stud medicine cabinet / shelves if that can work. If it were me I'd try to make it as open and airy as possible. This is not the bathroom for real storage. I'm thinking open shelves over the toilet and I would get non frosted glass for the top sash of the window if at all possible. I would also paint the wall a lighter color. Now for the final (bit crazy) idea. If I was going to live here forever I would go as far as adding a transom window to the hallway. You have the ceiling height and I'm assuming this is an old house because of that. Sucks that the original door casings are gone but prime opportunity to add a transom guilt free. You could even frost it a bit if wanted but it should be so tall no one could see inside without a chair. More on reddit.com

Just redid mine, well almost done that is lol. 64" to the front edge of the tub, 60" wide, same layout except toilet and sink are on left not right. On the bare wall across from the vanity and toilet, I cut a big hole in the wall and built a box to make recessed shelves. With the 4 inches of recessed space, I have (3) 8" deep shelves that only protrude 4 inches as to not take up much of the precious free space in the room. Thought it was a pretty clever space saving trick. I went with lotus leaf green walls, pretty dark considering it's small and there are no windows, but the vanity, sink, tub insert, trim are all pure white and the floor is sterling oak gray vinyl plank floor so the colors balance out very well. I could go on all day about how much I love these vinyl plank floors. Floating vanity by Ikea, euro small toilet by Ariel. My vanity is slightly too wide, a sacrifice my wife was willing to make in the name of good sinktop space at 31 inches. I'd try and give yourself atleast 40" between the tub and vanity for the toilet. I only have 33" and that extra 7" would have allowed me to mount the toilet paper roll on the side of the vanity comfortably. Using a free standing roll holder until I make a decision on that one. If this isn't a primary bathroom and you could do a pedestal sink, you'll be golden when it comes to free space. I needed storage and we didn't want to put an over the toilet cabinet up so we went with the vanity with drawers. The room feels bigger because the storage is down low and not in your face. Any questions let me know Edit: here's 2 pics You can see the recessed box in the mirror, it's not complete. Just finished cutting the trim that's going in tomorrow. Be easy Reddit I worked hard on this lol More on reddit.com

Option 1: If you don't have any more room to play with, could you move the door on the existing wall? Move vanity and toliet do and have a shower north. More on reddit.com
