The utilitarian bathroom is defined by the systems and practical objects it contains (water inlets, toilet, drains, ventilation, cabinets, sinks, shower, bath, and so on).
It is used primarily for hygiene and personal grooming.
In this type of space, the bathtub is a bathroom staple. It’s used for washing up and can occasionally be used for relaxation through immersion.
In such spaces, esthetics and quality of care aren’t factors in the purchase decision.
Utilitarian bathrooms are there because they need to be. They aren’t designed to be intimate personal spaces or increase the value of the home.
