Definition: Like a spa, a hot tub massages bathers with hot, bubbling water from built-in jets. Both require the same type of support equipment. But hot tubs are more rustic, made of wood, and resemble big barrels. Spas are made of concrete, acrylic reinforced with fiberglass or high-impact thermoplastics.
The terms are often used interchangably, especially with the popularity of a spa as a destination for physical benefits and relaxation.
Also Known As: Spa; Jacuzzi
Examples:
After a stressful day at work, Heather and Jack like to relax in the hot tub before dinner.
