We are currently working on plans to remodel our master bath. The current layout (picture) shows what walls are in place now. The door at the bottom of the picture connects to the kitchen. We would like to put a half bath in that general area and have it separate from the master bathroom. This is where we are having trouble deciding best layout for the walls.

There is a closet that stores the washer and dryer, which is staying the same, but we are open to ideas for the closet beside it (blue line is a wall), which has a separate door. Also wanting to change the shower. As of now the wall to the left (not beside shower) is tiled from floor to ceiling. This seems to make the space look smaller. We will be taking down the wall, but are not sure on what to do with layout.

Other info: this is a very old farmhouse with limited storage space. So anywhere we could add storage would be a plus.
