Echelon Step-In Vertical Cold Plunge Tub With 1 HP Built-In Chiller

The Echelon Step-In Vertical Cold Plunge Tub is an upright tub you enter by a ladder at the side, with a 1 HP chiller built into the shell according to Echelon's spec table. Echelon describes the position inside as a squat. The description labels it commercial grade, designed for both commercial and residential use. Echelon's commercial store lists an identical-looking Gen 2 for external commercial chillers.

The spec table gives a water range of 37 to 108°F, 3 to 42°C. The description gives a different low point: it says the tub reaches 2°C, 35.6°F. Echelon's cooling figure is for 300 L of water, dropped from 25°C to 3°C in 3.5 hours. The tub fills to 150 gallons, 567 L, and Echelon publishes no cooling time for a full tub. A 150W pump circulates the tub in 12 minutes at more than 25 L per minute, Echelon says.

For filtration, the description names a pre-filter and a 20-micron filter, and the spec table on the same page names a paper core filter system with ozone disinfection. Echelon does not say whether these are one system. The description also lists temperature, current and pressure sensors and reinforced copper piping. No app or Wi-Fi control is published for this model, and no manual for it was found on Echelon's support site.

One spec line gives 63 x 31.50 x 47.24 inches and 1600 x 800 x 1120 mm. The heights do not match, since 1120 mm is about 44.1 inches. Net weight is 308.6 lb. Gross weight is printed as 485 lb and 225 kg, which is about 496 lb. Echelon rates the structural load at 1,500 lb and gives no user height or weight limit. Power is 110 to 127 V at 60 Hz on a USA plug. Amperage, circuit size, a GFCI or dedicated circuit requirement, the drain method and any UL, ETL or CSA listing are not published.

The product page shows no lead time or ship date. At 485 lb the tub falls in the over 150 lb class that Echelon's shipping page sends by FedEx Freight, though the page lists treadmills, ellipticals and strength machines and not plunges. Hub Group in-home delivery with unpacking and light assembly is listed at $299.99 where available. The US store ships to the continental United States only.

Residential cover is 1 year in both Echelon's Terms and its recovery support article, and the Terms add 10 years on frames. The two disagree on commercial use: one copy of the Terms voids all warranties in a commercial setting, while the support article gives 6 months on cold immersion systems. Returns are written 3 ways. The refund policy allows 30 days from delivery with a prepaid label, fee free only when the product comes back brand new in its original packaging. The returns page offers a 60 day trial with $175 return freight and a 10% restocking fee. The recovery article puts return shipping on the buyer. None of the 3 names this tub.
