Do you have to keep a bathtub?

I would blow out all the pushed out parts of the walls. Behind the sink. And he two closets. Then I’d take a piece of the room and possibly part of your bedroom and create a big walk-in closet. This will create more symmetry and better flow. Then. Get a bigger vanity ( if we can shrink the window or st) wayyyy larger shower space and a free standing tub. For the toilet do you like a separate room? Or nah. I would leave it open but up to you. I’m thinking rich beautiful wallpaper. Light tiles.... I’m so excited to see this come together it’s a big project but will be sooo worth it. This is a great space. A lot of potential here!!

Can the window be moved? Can the space behind the door (presumably bedroom's space) be used for the bathroom?

Yes the window can be relocated. And really we hate the block window and want it gone/replaced. I don’t want to move into the bedroom since the bathroom is already roughly 16’x 13’ room.

We don’t use the tub at all. So it can go! My husband likes a toilet room so he can do his business in private while I’m getting ready.
