Designing a Spa Bathroom: What Luxury Wellness Really Costs
The principal bathroom has become the most personal wellness space in the luxury home.
From bathroom to private spa
Heated stone underfoot, a steam shower, an optional sauna, a soaking tub, spa lighting, and ventilation that manages humidity.
The investment range
In the Boston metro, a spa-grade principal bath generally runs from $90,000 to $250,000 or more.
Wellness is engineering
Steam and sauna require proper waterproofing, ventilation, and controls. Done correctly, the result supports sleep, recovery, and calm for decades.
