Choose options
Cold recovery. Restorative heat. One refined system.
The Finnmark SoulCold brings commercial-grade hot and cold immersion into one beautifully constructed plunge. Cool the water to 32.5°F, warm it to 108°F, and create a contrast therapy routine that is ready whenever you are.
Built for the full contrast therapy ritual
Move from an invigorating cold plunge to a deeply warming soak without purchasing or maintaining two separate systems. The SoulCold gives you precise temperature control across a wide range, making it easy to build cold immersion, warm recovery, or sauna-to-plunge contrast into your regular wellness routine.
Commercial-grade performance without a clinical feel
The SoulCold is engineered for repeated use in home wellness spaces, gyms, spas, recovery studios, and other commercial environments. Its integrated heating and cooling system maintains the selected temperature while the insulated construction helps reduce unnecessary temperature loss.
- Hot and cold temperature control Set the water anywhere from a bracing 32.5°F to a soothing 108°F.
- Commercial-grade Hitachi compressor Built to support consistent temperature management and repeated use.
- Standard electrical connection Operates on a 120V, 15-amp outlet with a NEMA 5-15P plug.
- Fully integrated design The tub, controls, sanitation equipment, and temperature system are housed within one streamlined cabinet.
A cleaner, more durable interior
The SoulCold replaces conventional acrylic and plastic interiors with premium 304 stainless steel—a material selected for its strength, corrosion resistance, clean appearance, and ability to withstand frequent use.
Its non-porous surface is easy to wipe down and helps create the polished, hygienic environment expected in a thoughtfully designed home or professional wellness space.
Clean water with less interruption
An integrated ozone generator, 20-micron filter, and high-flow circulation system work together to support water clarity and simplify routine upkeep.
- Integrated ozone sanitation Adds another layer of water care between plunges.
- 20-micron filtration Captures debris as water moves through the circulation system.
- High-flow circulation Helps move water efficiently through the filtration and sanitation components.
Details that turn recovery into a ritual
The SoulCold balances serious performance with thoughtful comfort, making the experience feel equally at home in a luxury residence or professionally designed recovery environment.
Canadian cedar backrest
An ergonomically positioned cedar insert adds natural warmth, support, and the distinctive aroma of real wood.
Wi-Fi temperature control
Check the water temperature and adjust your settings remotely so the plunge is prepared before your session begins.
LED mood lighting
Integrated lighting brings a calmer, more immersive atmosphere to early-morning recovery or evening relaxation.
Protect the water and preserve the temperature
The included commercial-grade cover is constructed from durable marine vinyl and insulated to help maintain the selected water temperature between sessions.
It also helps protect the water from dust and debris while giving the plunge a finished appearance when it is not in use.
Professional performance, thoughtfully refined
One system for hot and cold immersion
Build multiple wellness experiences around one tub rather than managing separate hot and cold systems.
Premium stainless-steel construction
The 304 stainless-steel interior delivers a more durable, hygienic, and elevated alternative to basic plastic tubs.
Made for home and commercial wellness
Commercial-grade components support frequent use while the integrated cabinet maintains a clean residential appearance.
Designed around everyday convenience
Wi-Fi control, integrated filtration, ozone sanitation, an insulated cover, and built-in lighting make regular use easier.
Finnmark SoulCold FAQs
Does the SoulCold provide both hot and cold water?
Yes. The SoulCold can cool the water to approximately 32.5°F and heat it to approximately 108°F. This allows it to be used for cold immersion, warm soaking, or contrast therapy routines.
Is the SoulCold suitable for commercial use?
Yes. Finnmark designed the SoulCold with commercial-grade components and durable 304 stainless-steel construction. It is suitable for premium home wellness spaces as well as gyms, spas, recovery studios, and similar professional environments.
How does the SoulCold keep the water clean?
Water care is supported by a 20-micron filter, an integrated ozone generator, and high-flow circulation. Routine testing, filter maintenance, and periodic water changes should still be completed according to Finnmark’s care instructions and the frequency of use.
What type of electrical connection is required?
The chiller is rated at 1,650 watts and 15 amps. It uses a standard NEMA 5-15P plug and connects to an appropriate 120V, 15-amp outlet. The final outlet location and circuit suitability should be confirmed for your intended placement.
Can I control the temperature remotely?
Yes. The built-in Wi-Fi controller allows you to check and adjust the water temperature remotely, helping you prepare the plunge before your planned session.
Will the cedar change the appearance of the water?
Natural cedar can initially release tannins that create harmless water discoloration. This typically decreases over time as the cedar is exposed to repeated use.
What warranty is included?
Includes 1 year limited warranty

Cold Therapy and Shock Proteins
When you submerge your body in freezing water, the sudden temperature drop triggers a powerful survival mechanism that releases "cold shock proteins". These specialized molecular helpers act like an internal repair crew, working rapidly to protect cells from stress, reduce systemic inflammation, and accelerate muscle recovery. By stabilizing cellular structures and promoting the synthesis of new proteins, this natural cold shock response helps the body build long-term resilience against physical stress while boosting metabolic efficiency and mental alertness.
