Before you buy
We could not find a working King Kool manufacturer website, and authorized dealer listings show every size and color sold out (October 29, 2026). We could not confirm the tub is still in production, so find out who handles warranty service before you buy one new or used.
- Standard: 80 x 27 x 31 inches, 90 to 95 gallons.
- Large and XL: both 85.5 x 36 x 27 inches outside; only the interior differs. Large holds 95 to 100 gallons, XL 120 to 125.
- Built-in chiller down to 39°F; 39 to 41°F is the recommended setting.
- Water care: ozone, a pump filter and an inline filter. Drain and refill at least every 3 months.
- Spa acrylic tub in a weather-resistant shell, reclined seat, armrests, adjustable feet, center drain. Bluetooth speakers and LED light are sold separately.
The tradeoff: 39°F is the floor, a couple of degrees warmer than chillers rated to 37°F, and the 80- and 85.5-inch lengths need real floor space. The listings don't publish power requirements; ask before you plan the circuit.
