The Finnmark SoulCold™ is a one-person hot and cold plunge tub: a 304 stainless steel tub in a cabinet of Canadian cedar slats, with a built-in chiller that cools the water to 34°F or heats it to 108°F. The tub opening is 47.1" long, 31.75" wide and 26" deep, and the whole unit is 79.75" long. It runs on 110–120 V, and Finnmark's manual requires a code-compliant 15 A circuit installed by a licensed electrician; the SoulCold arrives with a GFCI power cord and plug.
The chiller is built into one end of the cabinet behind a louvered panel, with the touchscreen controller at the same end, and LED lighting runs along the base. The water temperature is set on the touchscreen or in the Smart Life app on iOS and Android, and an insulated marine-grade vinyl cover closes the tub between sessions.
Hot and cold in one tub
The SoulCold's chiller both cools and heats the water. Finnmark's manual rates it at 4.45 kW of cooling and 4.36 kW of heating, with a water temperature adjustable from 34°F to 108°F. The manual notes that the temperatures it reaches can differ from these figures by up to 5°F, depending on the climate and sun exposure, the electrical supply, the condition of the filters and the volume of water.
Materials
- Tub: 304 stainless steel.
- Cabinet: Canadian cedar slats on the sides, with the chiller behind a louvered panel at one end.
- Backrests: Canadian cedar, preinstalled in the tub.
- Cover: insulated marine-grade vinyl, for when the tub is not in use.
Cedar releases tannins in water, so the water in a new SoulCold can take on a light amber tint. Finnmark's manual describes this as normal and harmless, and says it fades after several changes of water; the carbon filters supplied with the tub help absorb the tannins.
Water treatment and filtration
- Ozone generator: built into the chiller to disinfect the water.
- Filters: a 5" filter assembly that takes 5" 5-micron filters and 5" carbon filters. The SoulCold comes with two 5-micron filters and four carbon filters.
- Secondary screen: a mesh screen that catches hair and debris.
- Circulation pump: an 88 W DC motor.
Replacement Finnmark SoulCold chiller filters come in 4-packs of pleated or carbon filters, and can be added to the order on this page.
Controls and lighting
- Touchscreen controller: an LCD touchscreen at the chiller end of the cabinet sets the water temperature and shows fault codes.
- Wi-Fi app: the Smart Life app on iOS and Android sets and checks the temperature from a phone; the controller connects to a 2.4 GHz Wi-Fi network.
- LED lighting: lights along the base of the cabinet, with an LED remote.

The overall dimensions are from the dimension drawing in Finnmark's manual. The manual's parameter table lists the SoulCold at 79.75" × 35" × 30", so plan the space for the larger figures: 35.75" wide and 30" high. The weights and the chiller's size are from Bathing Brands, Finnmark's distributor.
What electrical supply does the Finnmark SoulCold need?
The Finnmark SoulCold runs on 110–120 V, 60 Hz. Finnmark's manual says it must be connected to a code-compliant 15 A circuit with AWG 14 wiring, installed by a licensed electrician and following all local and federal electrical codes, with a grounded NEMA 5-15 outlet for its plug.
The SoulCold arrives with a GFCI power cord and plug. The manual says to press the plug's TEST button to check that it cuts the power and RESET to restore it, not to use either button as an on/off switch, and not to press TEST while the tub is running. The cord and plug are intended for indoor use or light rain, and Finnmark recommends keeping them covered. If an extension cord is unavoidable, the manual specifies a 14 AWG cord with a single plug end rather than a power strip.
Where can the Finnmark SoulCold be installed?
Indoors or outdoors, on a sturdy, level surface. Finnmark's manual asks for a location that can support over 1,000 lb and, on a balcony or deck, a check of the load capacity by a qualified contractor or structural engineer before the tub is placed. Bathing Brands lists the SoulCold at 460 lb empty and 1,650 lb filled, so plan the floor or deck for at least the filled weight. The manual also asks for:
- 20" of clear space on every side, which makes an area of about 120" × 76", avoiding enclosed spaces;
- proper floor drainage, because the chiller can produce condensation in humid conditions and condensed water can run from its drain outlet;
- a freestanding position, not in a recess and not pushed up against a wall.
Using the SoulCold outdoors
Finnmark's manual allows outdoor use under a tent or shading device that protects the SoulCold from sun and rain, and asks that the touchscreen be kept shaded and out of the rain. The chiller is rated to cool in air temperatures of 59–109°F and to heat in 59–95°F. In heavy rain, flooding or direct sun above 95°F, the manual says to unplug the SoulCold and cover it or move it somewhere dry. Below freezing, Finnmark's warranty does not cover freeze damage, and the manual says the chiller should be moved inside or to a properly insulated area.
How is the Finnmark SoulCold set up?
Once the chiller is in its final position, lock the brakes on its casters and wait at least 24 hours before switching it on, so the refrigerant can settle. Check that the mesh filter and main filter are free of debris and hand-tight, then fill the tub with a garden hose. When the tub is half to three-quarters full, switch the chiller on: it primes itself, and it is primed when water flows from the top discharge port in the tub. If no water flows within a minute, Finnmark's manual says to hold the running hose to the bottom port to help it prime, and not to keep running a chiller that will not prime. Then fill until the water is about 6" below the top.
The chiller must never run without water in the tub: the manual says that damages the chiller and voids the warranty.
How is the Finnmark SoulCold maintained?
- Filters: check the filters, including the cartridge filters and the mesh screen, every 10 uses. Finnmark's warranty terms say the paper-core filter should be replaced every 30 days.
- Every 6 months: run spa cleanser through the system for 2 hours with nobody in the tub, then drain and refill it, and blow the dust out of the fan with compressed air. The manual warns that skipping the fan cleaning can cause early failure and denied warranty claims.
- Genuine parts: Finnmark's warranty can be voided by damage from filters and parts that are not genuine Finnmark Designs parts.
- Storage: drain the chiller before storing it for more than a month. The warranty is void if the chiller is left with stagnant water for 6 months or more without being run.
- Cleaning: unplug the SoulCold and wipe the surfaces with a damp cloth, without detergents or corrosive cleaners.
How is the Finnmark SoulCold delivered?
The Finnmark SoulCold ships free to the contiguous US by LTL freight, on a wooden pallet. Delivery is by appointment and curbside: the driver lowers the shipment to ground level and is not responsible for moving it further, so plan how the tub, about 460 lb out of its packaging, will be moved from the curb to where it will stand. The carrier will reach out to book the delivery appointment.
| Freight type | LTL truck, on a wooden pallet |
|---|---|
| Delivery | Curbside, by appointment, lowered to ground level |
| Package size | 85" L × 38.5" W × 41" H |
| Shipping weight | 500 lb |
Inspect the shipment before you sign. Photograph any damage to the packaging, note it on the delivery receipt, and contact us before setting up the tub.
Finnmark's installation and operation manual for the SoulCold covers the electrical requirements, placement, setup, maintenance and warranty, so you and your electrician can check them before you order.
