Our main bathroom was small and green with a window in the bathtub. This is the main bathroom used by the master bedroom AND the main floor powder room, all in a 7X6'2' footprint with no possibility to expand. We swapped the toilet and bathtub locations and changed for a 32X48" shower instead, giving us space for a small linen closet opening to the hallway. The doorway was squeezed over 2" allowing us to change from a 24" to a 26" door.
