I would like a bench or small chair in that space.

Have an outlet installed nearby for sitting and blow drying your hair.

can you keep a smaller window there.

It might be nice for extra light.

I am wondering if you need to review the layout (floor plan) of the entire bathroom. Don’t want to be thinking about parts of the room in a vacuum. If you post a plan, there are many people here who will help you by poking holes in it and suggesting improvements (not my forte). Bathrooms and kitchens are expensive rooms and you want to get it right before you do the work.

Why remove a window? Are there others in the bathroom?

I would keep the window and add plants!

Shawna Rushford, Contractor suggested installing a new transom window the full width of shower inside the shower. If I kept the existing window, the shower would extend right up to the right side of the existing window. Existing window then wouldn’t be centered in its space and might look strange.

Here is the proposed floor plan. I’d love to hear everyone’s thoughts.

Another possible floor plan (option 2)

Option 2 floor plan keeps existing window and doesn’t have new transom window in shower

Emilyam819, thank you. Option 2 is less expensive, and if it looks good, I’m all for keeping costs down. Linen Closet already exists. Additional Linen Closet will replace the current stall shower in the water closet room. I’ve always felt that there was something “off” about the bathroom layout, but didn’t know what it was. You identified it: that the Linen Closet isn’t even with the other walls. I like the idea of a hamper. Design Interior South suggested a base cabinet with a pull-out or tilt-out hamper. I am leaning toward that idea now.

I would do a cushioned bench with storage under it in place of shelves. I use the cushioned bench outside my shower far more than my shower bench.

I am not a fan of option 2. The space between the shower and master closet doesn't seem spacious, plus you would be facing a wall that housed the shower head and controls when you enter the bathroom.

I am not understanding how two linen closets are going to work. I would remove the existing one and if you need more storage, put in a tall cabinet outside the bathroom facing the shower (to the left of the window)

I really like Roarah's bench storage solution.

Another idea to save money, would be option one with a slightly smaller shower in length, say 54 inches long or as far as you can go till you are near the existing window. Increase the depth from 42 inches to 48 inches. I'd still remove the existing closet.

Roarah, thank you for that suggestion. I'm so glad that I posted this request for advice.

Karenseb, thank you for pointing out that Option 2 would mean facing a wall when entering the bathroom. I hadn't focused on that at all.

Yes, good point. Allow me to change my vote to the shape of the shower in Option 1, but no modification to the windows. Also, the existing linen closet is just so Tetris- like. The new linen closet should open from the bathroom. Remember to plan for towel bars, hooks, the bench, trash, laundry.
