Sweat Kingdom · ReGen · The Blast Residential
The 36°F home cold plunge with the chiller, basin, and chassis of a commercial unit.
A 1HP chiller that pulls water to 36°F. Robust stainless steel construction. A 40%-larger interior than the XL. High-flow dual circulation. No special plumbing, no special electrical.
The Blast Residential shares its chassis, chiller, and basin geometry with the Commercial unit. The difference is the sanitation stack — the Residential drops the automated chlorine feeder, ozone system, NSF50 filtration, and integrated skimmer that high-traffic facilities need, in exchange for a simpler, lower-overhead home setup. The performance side stays intact: 36°F minimum, dual-flow circulation that breaks through the thermal barrier, and a basin large enough for an upright seated plunge instead of a knees-to-chest crouch.

Three things that put The Blast ahead of a typical home cold plunge
1HP chiller
A heavy-duty chiller, not a residential-grade cooler. It reaches 36°F and recovers between plunges fast enough that you don’t have to schedule around the cooldown.
High-flow dual circulation
On-demand dual-flow system breaks through the thermal barrier — the layer of slightly warmer water that forms around your body when you sit still — and keeps the cold actually working on you.
Stainless steel framing, indoor/outdoor
Robust stainless steel framing and steel cabinetry resist corrosion and don’t degrade in a humid pool room. Engineered for indoor or outdoor use without re-rating.
Why people pick The Blast Residential over entry-level home plunges
Real 36°F, not a marketing number
The 1HP chiller actually delivers the temperature listed. Light-duty residential systems often quote 36°F but only sustain it in a cool environment — The Blast holds it.
Upright seated geometry
A 40% larger interior than the XL means you sit instead of fold. Important when your plunge protocol is 3–6 minutes — the position you’re holding determines whether you can finish the timer.
No specialty install
No dedicated plumbing, no dedicated electrical. Self-contained design means you choose the spot and the tub fits — not the other way around.
Outdoor-ready year round
Stainless steel framing handles outdoor exposure across seasons. Same chassis as the Commercial — engineered for extremes like Arizona summer and Midwest winter.
A closer look
A home unit built around the same hardware as a commercial install
The chassis, chiller, basin geometry, and dual-flow circulation system are shared with the Commercial unit. What gets stripped out is what a home owner doesn’t need: facility-grade sanitation automation, NSF50/UL/VBG certifications, and the commercial warranty terms. The performance side — the part you feel when you step into 36°F water — is unchanged.
The thermal barrier matters more than the temperature display
Sit still in cold water and your body warms the few millimeters of water around your skin within seconds, blunting the effective dose of cold. The on-demand dual-flow system disrupts that barrier and keeps fresh cold water in contact with the surface — the difference between sitting cold and being plunged cold.
Two finishes, no surprises during install
Standard finish is white basin with charcoal skirt; white basin with white skirt is available. The unit ships ready to run — fill, plug in, and start the chiller. No dedicated plumbing, no breaker work, no waiting on a contractor.

Frequently asked questions
Same chiller (1HP), same 36°F minimum, same 40%-larger interior, same stainless steel framing and dual-flow circulation. The Commercial adds an automated chlorine feeder, ozone sanitation, NSF50-certified filtration, UL-certified compressor, VBG-certified suction, an integrated skimmer with removable hair catch, and a 12-month commercial warranty — the certifications and automated sanitation that high-traffic facilities need. The Residential drops those in favor of a simpler home setup.
No. The Blast Residential is self-contained. Fill, plug in, and run.
Yes. Built for indoor or outdoor use across season changes — same chassis-rated extremes (Arizona summers, Midwest winters) as the Commercial unit.
36°F minimum, set by you. The 1HP chiller holds the set point — this is heavy-duty cooling, not a residential-grade compressor that fades under load.
Upright. The interior is 40% larger than the XL — designed so adults sit comfortably with the water at chest height rather than folding knees-to-chest.
2-year warranty included. Optional 3-year and 4-year warranty extensions are available at order.
Two: white basin with charcoal skirt (standard) or white basin with white skirt. Custom skirt wraps are a commercial option, not a residential configuration.
