Are we to assume there is a window over the tub?

Get off the computer program. Use paper, pencil, feet and inches. 1/4 or 1/2 inch to a foot and make a scaled drawing . What's the actual size of the window if one exists ? How wide is the door entry? Thirty inches?

I agree a nice 2D floor plan showing toilet placement now since moving toilets is often a really big deal. I actually dislke huge bathrooms I am a clean freak and so smaller is just easier Do you have a good closet near the bathroom . Sometimes a floor plan showing the whole master suite is very helpful IMO a nice 9 x10 bathroom is perfect .

Your room is large enough to have the toilet in a separate room with a door - for sure do that somehow. A huge shower is a lot of cleaning and also can be very cold.

Thank you all for the reply's. Yes, there is a Window over current tub and it is 66" long and 58" wide, made with glass brick. Contractor is encouraging me to remove it but I think the space needs it, although the glass brick is dated in my mind. Pencil sketch below, I think you can tell why I would rather use Computer lol.. Would actual pictures of current help?
