A floor plan with ALL DIMENSIONS will help you get the best help. Impossible to offer much wiithout it.

One idea that often frees up space is to make a single walk-in closet and put it between the bedroom and the bathroom. Then the bathroom can have the extra width for a bigger shower and a tub, and the walkway into the room stays wide. If you post the plan with the room sizes, people can show you where to move the walls.

"If you were to redesign this space with a walk in closet, walk in shower and a bathtub, how would you do that?"

Create an current floor plan to scale showing the surrounding spaces.
