Cold Plunge Basics
A cold plunge is a temperature-controlled tub designed to help your body recover, refresh, and energize through cold water immersion therapy. Water temperatures typically range from 39°F to 59°F, triggering numerous health benefits such as improved circulation, reduced inflammation, and faster recovery.
Most users set their plunge between 45°F and 55°F. Beginners may start around 55°F and gradually decrease the temperature as tolerance builds. Athletes and experienced users often prefer 39–45°F for optimal recovery.
The ideal duration is 2–5 minutes per session. Some users work up to 8–10 minutes, but shorter, more frequent plunges are usually more effective and safer. Listen to your body — shivering or numbness are signs to get out and warm up.
Many people use a cold plunge 3–5 times per week, while others enjoy it daily as part of their recovery or mental wellness routine. Consistency is key for lasting results. Contrast therapy with a sauna or hot tub and then cold tub is a popular wellness routine.
It depends on your goal:
- After a workout: Best for reducing soreness and inflammation.
- Before a workout: Helps wake up the body and sharpen focus, though it may slightly reduce muscle activation for some athletes.
Many users also pair cold plunging with sauna use for contrast therapy — alternating between heat and cold for amplified recovery benefits.
Yes, with supervision. Keep the temperature at 100°F or lower and limit soak time to 10–15 minutes. Children should never be left unattended in a hot tub.
Cold Plunge Health & Wellness Benefits
Cold plunging can help:
- Reduce inflammation and muscle soreness
- Improve circulation and heart health
- Boost mood and mental clarity
- Strengthen the immune system

Yes — research shows that cold water immersion can release endorphins, elevate mood, and lower stress hormones like cortisol. Many users report feeling calmer and more mentally clear after regular plunging.
Cold plunging is safe for most healthy adults, but risks can occur if:
- You have cardiovascular or respiratory conditions
- You stay in the water too long
- The temperature is too low for your tolerance
Always start gradually, consult a doctor if you have medical concerns, and never plunge alone.
Cold Plunge Cost, Operation & Installation
Cold plunge systems typically range from $4,000–$10,000+, depending on size, materials, chiller type, and filtration quality. Entry-level models may cost less, while commercial-grade units with advanced filtration and temperature control cost more.
Most cold plunges cost $15–$30 per month to operate, depending on temperature settings, insulation, ambient conditions, and energy rates. Modern chillers are energy-efficient and designed for continuous use.
Most residential cold plunges operate on a dedicated 115V or 230V electrical circuit depending on the chiller system. A licensed electrician should install the outlet according to manufacturer specifications.
Cold plunge chillers circulate water through a refrigeration system, removing heat to maintain your set temperature. Many also include ozone and filtration systems to keep the water fresh and sanitary with minimal maintenance.
Cold plunges can often be installed by homeowners if electrical and foundation requirements are met. However, The Hot Tub Store offers professional delivery and setup services to ensure safe installation and optimal performance.
Cold plunges should sit on a flat, level, and solid surface, such as a concrete pad, deck, or patio. The base must support the filled weight — often between 1,500–3,000 pounds. Indoor installations require waterproof flooring and adequate drainage.
Yes — many people install cold plunges in home gyms, garages, bathrooms, or basements. Ensure proper flooring, ventilation, and electrical access.
