Capability score

83.3 / 100

How much of the work the product does for you: temperature control, insulation, sanitation and the warranty behind it. A tub with no chiller scores lower because you supply the ice, not because it is built worse.

    chiller included, min temp f, water capacity gal, insulated, sanitation system, sanitation methods, placement, warranty years, plumbing, warranty, dimensions, weight, price

    • chiller included: Page states an integrated 0.25 HP chiller. Previously recorded as relayed via a search summary on 2026-09-08.
    • min temp f: Page states cold only, down to 39 F. The record carried 36 F, relayed, which the page does not support. Previously recorded as relayed via a search summary on 2026-09-08.
    • water capacity gal: Page states 95 gallons filled, the volume it runs at, and separately a 134-gallon maximum capacity. The 95 is recorded because it is the working volume the other figures describe; the 134 is the tub's limit and is a different measurement. Neither is derived from the other. Previously recorded as relayed via a search summary on 2026-09-08.
    • insulated: Page states insulation. Previously recorded as relayed via a search summary on 2026-09-08.
    • sanitation system, sanitation methods: Page states filtration and ozone. Previously recorded as relayed via a search summary on 2026-09-08.
    • placement: Page states the tub is rated for indoor and outdoor use, explicitly. The record carried the same pair as prototype data; it is the maker's own statement now.
    • warranty years, warranty: Page states a 5-year limited warranty. Previously recorded as relayed via a search summary on 2026-09-08.
    • plumbing: Page states 120 V, 15 A, with 450 W of cooling. Recorded as a standard 120 V outlet. The page does not call for a dedicated circuit, and none is inferred.
    • dimensions: Page states an exterior of 70 L x 33 W x 35 H in. Its interior, separately, is 40 L x 25 W x 31 D in; the record carried those interior figures as the product's dimensions.
    • weight: Page states 365 lb dry. Filled, it states 1,155 lb with 95 gallons of water.
    • price: Page states $8,499 USD for the base configuration, California Redwood with no light, against a compare-at price of $9,499. Cedar adds $200 and a light adds $320; neither is included here. Availability is not recorded from this reading. The record carried $9,599, relayed on 2026-09-08.
