How big should a master bathroom be?

Typical large master bathrooms are typically 100-120 square feet or larger. A functional South Jersey master bathroom accommodates a walk-in shower, a comfort-height double vanity, a comfort-height elongated toilet, and dedicated storage. A more generous master bathroom includes separate zones for bathing (ideally a freestanding tub), showering, toileting, grooming, and linen/laundry storage.
