The OG Plunge Tub is sold through Sweat Kingdom, the luxury sauna retailer, and manufactured by its vendor partner ReGen Total Wellness in Arizona. The listing runs through Shopify Collective, so Sweat Kingdom is the storefront and ReGen builds and ships the tub. Worth knowing before you buy, because sales and service route through two companies instead of one.
The configurator is the story. $4,990 buys the Standard tub (sized for users up to 6 feet) with the light-duty 1/4HP chiller and a 2-year warranty included. From there, X-Large sizing for taller users adds $500, the heavy-duty 1/2HP chiller adds $750, and warranty extensions run $400 for a third year or $600 for a fourth, topping out at $6,840 fully loaded. ReGen rates the 1/4HP chiller to a 39°F floor and the 1/2HP to 36°F, and states 2-plus inches of high-density insulation, integrated filtration and sanitation, indoor or outdoor placement, no special plumbing or electrical work, and 1-2 week shipping.
Where it gives ground: the published spec sheet is thinner than the category leaders'. The product page lists no dimensions, gallon capacity, or noise figure, so buyers who check every number should request those in writing before ordering. And once you spec the Standard tub with the 1/2HP chiller at $5,740, you are within striking distance of The Plunge, which counters with a finished tub and 24-month coverage on both tub and chiller. The OG's case is configurability: pick the chiller, pick the size, pick the warranty, and get a 36°F-rated build under $6K.

Sweat Kingdom The OG Plunge Tub - buyer FAQ
How much does the Sweat Kingdom OG Plunge Tub cost?
The base build is $4,990: Standard size (up to 6 feet), the light-duty 1/4HP chiller, and a 2-year warranty, verified 2026-08-16 via sweatkingdom.com Shopify data. X-Large sizing adds $500, the heavy-duty 1/2HP chiller adds $750, and 3- or 4-year warranty extensions add $400 or $600. A fully loaded build tops out at $6,840.
Which chiller should I pick, the 1/4HP or the 1/2HP?
ReGen rates the light-duty 1/4HP chiller to a 39°F floor and the heavy-duty 1/2HP to 36°F, a $750 upgrade. The bigger compressor buys cooling headroom, which matters in hot climates and for back-to-back sessions. If the tub lives somewhere cool and 39°F is cold enough for you, the base chiller saves the $750.
Who actually makes the OG Plunge Tub?
ReGen Total Wellness builds the tub in Arizona; Sweat Kingdom sells it through a Shopify Collective vendor listing. In practice one company takes your order and another manufactures and ships it, with the page stating 1-2 week shipping. Before ordering, get in writing which of the 2 companies handles warranty claims and replacement parts.
What warranty does the OG Plunge Tub come with?
A 2-year warranty is included in the $4,990 base price, extendable at checkout to 3 years for $400 or 4 years for $600. The included 24 months matches The Plunge's standard coverage, while Renu Therapy's 60-month tub warranty remains the category benchmark. Factor the extension cost into any price comparison you run.
