Whirlpool & Jetted Tubs
Updated February 20, 2026
Feature built-in water or air jets for hydrotherapy massage. Available in alcove, drop-in, and freestanding configurations.
Overview
Whirlpool and jetted tubs use built-in pumps to push water or air through jets in the tub walls for hydrotherapy massage. Water jets (whirlpool) provide deep-tissue pressure; air jets produce gentler, effervescent bubbles. Some tubs combine both. They require an electrical connection (dedicated GFCI circuit) for the pump motor. Available in alcove, drop-in, corner, and freestanding configurations. Therapeutic benefits include muscle relaxation, improved circulation, and stress relief. The tradeoff: higher cost, more maintenance, and cleaning the jet plumbing regularly to prevent biofilm buildup.
Pros & Cons
- Therapeutic massage
- Muscle relaxation
- Luxury experience
- Expensive
- Higher maintenance
- Requires electrical connection
- Harder to clean jets
Key Features
- Water jets (whirlpool): high-pressure streams for targeted muscle massage
- Air jets: thousands of tiny bubbles for gentle, full-body relaxation
- Combo systems offer both water and air jet options with separate controls
- Inline heater maintains water temperature during long soaks (premium models)
- Dedicated GFCI electrical circuit required -- typically 15-20 amp, 120V
Sizing & Selection
Available from 60-inch alcove size up to 72+ inch freestanding and corner models. Larger tubs hold more water (60-100+ gallons vs 40-50 for a standard tub) so verify your water heater capacity. A 60-gallon jetted tub at 104 degrees needs a water heater that can deliver that volume. Tank-style heaters may need a recovery period; tankless handles it on demand.
Installation
Alcove jetted tubs install similarly to standard alcove tubs but require a dedicated electrical circuit run to a GFCI outlet near the tub motor access panel. Drop-in models need a deck or surround built to support the tub rim. The pump motor needs an accessible service panel for maintenance. A plumber handles the water connections; an electrician handles the circuit. Both are needed.
Maintenance
- Run the jets with hot water and a jet cleaner (BioGuard, Oh Yuk) monthly to flush biofilm from the plumbing lines.
- After each use, run jets for 30 seconds on plain water to flush residual soap and oils.
- Clean jet nozzles with a toothbrush and vinegar to remove mineral deposits.
- Check the pump motor access panel annually for leaks around the pump seals.
- Drain and deep-clean the jet system every 3-6 months with a full cleaning cycle.
Buying Tips
- Air jets are easier to maintain than water jets -- less biofilm buildup because air does not sit in the lines.
- An inline heater (-400 premium) is worth it. Without one, the water cools during a 30-minute soak.
- Check the pump noise level. Belt-driven pumps are quieter than direct-drive. Read reviews specifically about noise.
- Acrylic is the standard material. Avoid fiberglass jetted tubs -- they flex under the weight and stress the jet fittings.
- Budget -500 for the electrical circuit if one does not already exist near the tub location.
