Bathroom Layout help needed. Adding additional bath into existing space
First picture was the existing layout - pocket door to the toilet shower room, 2nd picture is my proposed new layout, and pics of the current state of the bathroom and closet.
We are remodeling the master bath in our house it has a concrete slab so we'd like to not move too much of the existing water lines and we have a large window in the bathroom. I cannot figure out the best way to lay everything out. The tub under the window we'd like to be freestanding but not sure how to get water to it. Walk-in closet is not completely necessary there are 2 large wall closets in the master though I did try to keep a small closet area in the layout I came up with.
Any and all help appreciated and would love recommendations on how I can create a rendering of the ideas so I can see what it would look like. Thank you!
