Shooting bathrooms can be challenging because there are multiple elements in a fairly small area. I will generally shoot multiple angles in the master bath because I have to cover a larger space. I position the tripod at a lower height because I want to reveal the flooring but high enough to capture the trey ceiling. In this case, I also opened the door to the walk in closet to provide a bit more depth and showcase the closet (I might be short on shots and this way I can cover one angle of the bathroom + the master closet in one image. It’s not shown, but i would setup the 2nd shot toward the double vanity on the opposite wall.
As far as exposure, most master baths will have a large window so the -2 exposure will take care of it while the +2 and +1 will provide enough exposure to capture detail in all the elements.
