SaunaLife Model S1NC Package – 1-Person Hot & Cold Immersion Tub with Chiller/Heater (Natural)

One tub. Two therapies. A bracing 32.5°F cold plunge after a hard workout or a sauna session, or a warm 108°F soak at the end of a long day. The SaunaLife Model S1NC Package gives you both from a single, beautifully crafted immersion tub at home.

Designed by SaunaLife and handcrafted in Northern Europe, this package pairs the Model S1N tub, a contoured fiberglass basin wrapped in natural Thermo-Spruce, with the FDC-1A combination chiller/heater. The tub arrives fully assembled. The chiller runs on standard 110–120V household power. You set the temperature from the on-unit touchscreen or from your phone.

Cold immersion and warm-water soaking are two of the oldest recovery practices there are. The S1NC puts both within a few steps of your back door, ready whenever you are.

Why This Stands Out

•      Hot and cold in one system. The FDC-1A cools water to 32.5°F and heats it to 108°F, so one tub covers cold plunging and warm soaking. No second unit, no second footprint.

•      Nordic craftsmanship. The tub surround is thermally modified spruce (Thermo-Spruce), which SaunaLife rates to last up to twice as long as cedar, with strong thermal resistance.

•      Arrives fully assembled. No kit to build. Set the tub on a level base, connect the chiller, fill, and power on.

•      Clean water, built in. An integrated ozone generator works with a 5-inch filter assembly to help keep water clear and hygienic between changes.

•      Control from anywhere. Wi-Fi app (iOS and Android), on-unit LCD touchscreen, and an included LED remote.

•      Comfortable for one. 124 gallons of water in a deep, body-contoured basin: 34.4 inches across and 36 inches deep.

FDC-1A Chiller/Heater

•      Water temperature range: 32.5°F to 108°F (0.3°C to 42°C)

•      Cooling capacity: 2.81 kW | Heating capacity: 3.38 kW

•      Built-in ozone filtration with 5-inch filter assembly

•      Wi-Fi app control plus on-unit LCD touchscreen and LED remote

•      Quiet-running design

•      Plug-and-play: 110–120V, 60Hz with inline GFCI cord (NEMA 5-15 plug)

•      Compact footprint: 21.3"W x 15.4"D x 25"H

Installation & Power Requirements

•      Electrical: 110–120V, 60Hz. A dedicated, code-compliant 15-amp circuit (14 AWG) installed by a licensed electrician is recommended. Avoid power strips; if an extension cord is unavoidable, use a single-outlet 14 AWG cord.

•      Foundation: A level, solid base at least 3 inches above surrounding ground. The filled tub weighs more than 1,150 lbs, so the surface must be rated to carry that load.

•      Chiller placement: Level with the tub or slightly lower, with the tub water line above the chiller inlet. Allow at least 20 inches of clearance on all sides and 60 inches in front of the fan.

•      Plumbing: 3/4-inch NPT chiller connections; 1-inch tub drain. Connect chiller inlet to tub outlet and chiller outlet to tub inlet, open both valves, and fill the tub before powering on.

•      Before first use: Keep the chiller upright and unplugged for 24 hours after delivery, then prime the pump with water before startup.

•      Outdoor installation: When installed outdoors, the chiller must be protected with a weatherproof cover. Unplug and cover it during heavy rain, flooding, or direct sun above 95°F. In freezing weather, move the chiller indoors, drain the tub, and leave the drain valve open.

•      Shipping: $695 flat rate to the continental US. Ships LTL freight with curbside delivery. Alaska, Hawaii, and Puerto Rico: please contact us for a quote.

•      Delivery: Plan for help moving the tub (approx. 265 lbs packaged) from the curb to its final location.

Maintenance

•      Check and rinse the 5-inch filters regularly; replace them on the schedule in the owner's manual

•      Drain and refill the water periodically as directed in the owner's manual

•      Use an insulated cover between sessions to keep out debris and hold temperature (SaunaLife S1 Cover sold separately)

•      Protect the chiller from weather as outlined above, and winterize in freezing conditions

•      Thermo-Spruce is a natural wood; expect natural color variation and weathering over time outdoors

Who This Is For

The S1NC is for anyone who wants cold plunging and warm soaking as a daily habit rather than an occasional trip to a gym or spa. It suits athletes and active people who train hard and want a dedicated recovery routine, sauna owners who want a cold plunge alongside their sauna, and anyone building a home wellness space who values real wood, European craftsmanship, and the ability to switch between hot and cold with the touch of a button.
