The Plunge review

The Plunge is the safest all-round choice we found because it combines a full-length laydown tub, a chiller that reaches 37°F and a mid-range sale price. Plunge lists it at $5,945 during its Black Friday sale against a comp value of $8,490, and the sale adds a free 2-year extended warranty and a $200 maintenance kit. The acrylic and fiberglass tub fits people up to 6'8" and sits beside the separate Pro Chiller Gen 2, which connects with two hoses and runs on a dedicated 120V, 15A circuit, so no plumbing work is needed. The Plunge app sets the temperature and reminds you about filter care, and a $500 heater option takes the water to 104°. Plunge offers a 30-Day Guarantee and free delivery, and the tub is assembled in California. The trade-offs: the standard warranty is only 1 year, heating is extra and the price depends on the current promotion.
