How to Choose the Right Commercial Infrared Saunas: A Businesses Need to Know Guide

Choosing the right commercial infrared sauna can significantly impact your business’s success—whether you run a gym, wellness center, spa, hotel, physical therapy clinic, or luxury rental property. Unlike residential units, commercial infrared saunas must be designed for daily high-volume use, durability, safety, and multi-user comfort.

This guide walks you through everything a business should consider before investing: sauna types, heater technology, EMF safety, materials, warranties, and vendor selection. Let’s help you make the right purchase for your brand and clients.


1. Understand Infrared Sauna Technology

🔥 Types of Infrared Heaters

  • Far Infrared (FIR): Penetrates 1.5–2 inches into tissue, ideal for detox, pain relief, and cardiovascular benefits. Most common type.
  • Full Spectrum: Includes far, mid, and near-infrared. Near infrared aids skin repair and inflammation. Best for high-end wellness facilities.
  • Carbon Panels: Even heat distribution, low surface temperature, energy efficient, long lifespan.
  • Ceramic Rods: Hotter and more intense, but with less coverage area and more energy use.

🔒 EMF Levels

  • Prioritize models with low EMF (<3 mG) or ultra-low EMF (<1 mG) ratings
  • Check for independent third-party EMF testing
