Best Gym Sauna Heaters and Sauna Kits – Top Picks for Commercial Use

Adding a sauna to a gym or fitness center enhances recovery, boosts member retention, and provides a premium wellness experience. However, choosing the right sauna heater and sauna kit is essential to ensure durability, efficiency, and proper functionality for high-traffic use.

This guide covers the best sauna heaters for gyms, the correct electrical setup for commercial saunas, and the best sauna kits for those looking to install a complete sauna solution.

1. Choosing the Right Sauna Heater for Gyms

Understanding Gym Sauna Electrical Requirements

Most home saunas use a 240V/1PH (single-phase) electrical setup. However, commercial saunas in gyms typically require 208V/3PH (three-phase) power to handle the demands of continuous, high-traffic use. Choosing a heater that supports 208V/3PH is crucial for safety, efficiency, and compliance with commercial electrical codes.

Best All-Around Gym Sauna Heater – Harvia Club Series

For most gym saunas, the Harvia Club is the best all-around commercial sauna heater due to its:

• Reliable stainless steel elements designed for continuous 24-hour use.
• 208V/3PH compatibility, making it ideal for gym saunas.
• Analog controller option with a tamperproof cover to prevent unauthorized adjustments.
• Affordability and durability, making it a great investment for fitness centers.

Best for Large Gym Saunas – Harvia Virta Pro 20kW

For extra-large gym saunas, the Harvia Virta Pro 20kW provides:

• High power output (16kW or 20kW) for large sauna spaces.
• 208V/3PH compatibility to handle heavy commercial use.
• Digital controller with WiFi integration, allowing remote control via the MyHarvia app.
• Superior heat retention and reliability, making it ideal for high-end gyms and spas.

Best for Small Gym Saunas – Harvia KIP

For smaller gym saunas, the Harvia KIP is the best option. It features:

• Compact design for saunas with limited space.
• Efficient heating with external digital controls.
• WiFi capability for convenient remote operation.
• Affordable pricing, making it ideal for boutique fitness centers and personal training studios.

2. Best Sauna Kits for Gyms

If you are installing a sauna in a gym from scratch, choosing a pre-designed sauna kit is the most efficient solution. These kits include pre-cut panels, benches, doors, and heating options, simplifying the installation process.
