I have noticed "Plunge Therapy" in some reviews & comments, what is that about?

"Plunge Therapy" was our original brand name, initially we launched as a cold plunge niche company with a single offering - our flagship Byron Plunge in Matte Black & Matte White. As we expanded our offerings to include saunas and other wellness products, we rebranded to NORDHAUS to better reflect our broader commitment to wellness and design.

3. Buyers Guide

Traditional Saunas

Our Traditional Saunas use an electric heater to heat the air inside a Canadian-Hemlock cabin. Temperatures typically reach 80°C plus, with the option of low or high humidity heat, creating an intense heat therapy experience.

 

Key Benefits

  • Deep muscle relaxation
  • Increased circulation
  • Full-body detox through sweating

Things to Consider

Traditional saunas require a dedicated indoor or an outdoor space (which it will need to be protected from the elements). Our Traditional Saunas require an electrician to wire the heater unit.

 

Ideal For

Those who enjoy a classic sauna experience with intense heat and the calming ritual of a traditional steam session.

Infrared Saunas

Infrared saunas use radiant heat panels to warm your body directly, rather than heating the air. This creates a gentler, more comfortable experience, with cabin temperatures usually up to 65°C.

 

Key Benefits

  • Lower ambient heat for comfort
  • Deep tissue heat penetration
  • Energy-efficient and easy to install

Things to Consider

Infrared saunas are plug-and-play and come with a 10amp standard wall plug.

 

Ideal For

People with limited space, first-time sauna buyers, or anyone seeking a lower-heat, more therapeutic option for daily use.

Ice Baths

 

Ice baths involve immersing your body in cold water—usually between 3°C and 15°C—to trigger physical recovery and mental resilience. They are used widely by athletes, wellness practitioners, and biohackers.

 

Key Benefits

  • Reduces inflammation and soreness
  • Boosts blood flow and circulation
  • Builds mental toughness and stress resilience

Types Available

Nordhaus offers high-performance ice baths like the Noosa Plunge and Byron plunge that come in Matte Black or White, which can be paired with a 1HP or a 2HP Commercial unit.

 

Ideal For

Fitness enthusiasts, athletes, or anyone looking to recover faster and boost their mental and physical resilience.

4. Ice Bath Care

How do I clean the ice bath?

Clean it just like a bathtub—using a spray bottle with diluted vinegar and a soft cloth. Avoid using harsh chemicals to preserve the acrylic surface.

How often should I change the water in the ice bath?

For home use, monthly water changes are typical. In high-use or commercial settings, you may need to replace water more frequently based on usage levels and hygiene requirements.

How often do I need to replace/clean the filters?
  • Cartridge Filter

For light personal use, every 4–6 weeks is sufficient. For commercial or heavy use, clean the filter more regularly. Note that sauna users may clog the filter faster due to open pores releasing oils and sweat.

  • Hair Filter

For light personal use, clean the hair filter approximately every 4 weeks, or sooner if you notice a reduced water flow from the chiller. In commercial or high-usage settings, it’s recommended to clean the filter every 1–2 weeks to ensure optimal performance.

5. Sauna Care

How do I clean my indoor sauna?

Clean your sauna regularly to prolong its life and maintain hygiene:

  • Use diluted white vinegar in a spray bottle—never chemicals.
  • Spray benches, walls, and floor slats, then scrub with a soft-bristle brush.
  • For tough stains, gently sand the wood using fine sandpaper.
  • Keep the door open post-session to allow airflow and reduce moisture              buildup.
