Jetted Bathtubs for Home Hydrotherapy
Jetted bathtubs use a sealed pump to recirculate the tub's own water through strategically placed nozzles, delivering targeted pressure massage to the back, lumbar, hips, calves, and feet. Unlike a quiet soaking tub or a bubble-driven air bath, a jetted system moves a high volume of water at adjustable pressure — which is why it remains the go-to choice for muscle recovery and hydrotherapy at home.
Because the pump and plumbing loop add bulk behind the tub shell, jetted models are most often built as corner or alcove units where the motor can be hidden behind an access panel. Power requirements are also stricter than a standard bathtub: every jetted tub needs a dedicated GFCI-protected 20-amp circuit run to the motor location.
Browse over 270 jetted tubs in acrylic, fiberglass, and cast iron, with adjustable jet counts ranging from 6 to 20+ nozzles.

Frequently Asked Questions
What electrical hookup does a jetted tub require?
Every jetted bathtub needs a dedicated 20-amp, 120-volt circuit with GFCI protection wired to the pump location. The GFCI breaker should be accessible — typically at the main panel or a sub-panel, not buried behind the tub. Larger 1.5 HP and dual-pump models may require a 240-volt circuit. A licensed electrician must confirm load calculations and local code compliance before installation.
How do I keep the jets clean and prevent biofilm?
Because jetted tubs recirculate the bathwater through internal lines, residual water left in the loop can grow biofilm — a slimy bacterial film that releases as black flakes during the next bath. Flush the system monthly by filling above the highest jet, adding a tub-system cleaner (or 1/2 cup dishwasher detergent plus 1/2 cup bleach), running jets 15 minutes, draining, refilling with cold water, and running another 10 minutes.
Is a jetted tub the same as a whirlpool tub?
The terms overlap, but there is a distinction. Whirlpool is the trademarked term Jacuzzi popularized for water-jet tubs, and most retailers now use whirlpool and jetted interchangeably for water-recirculating systems. Both differ from air baths, which push warm air bubbles through pinholes for a softer, effervescent sensation rather than targeted pressure massage.
Does a jetted bathtub need extra floor support?
An acrylic jetted tub weighs 90–140 pounds empty, but filled to the overflow with a bather it can exceed 700–800 pounds concentrated over a 15-square-foot footprint. Standard 2x10 floor joists at 16-inch spacing handle this on a first floor over a basement. For second-floor installations or older homes with 2x8 joists, sister-joisting beneath the tub footprint is a common precaution.
How long can I run the jets in one session?
Most residential pumps are rated for continuous duty up to 20–30 minutes, which also matches the recommended hydrotherapy session length — longer immersion in jetted warm water can lead to dehydration or lightheadedness. After the session, leave the tub cover off and let the air gap dry the jet faces to slow biofilm growth between uses.
