How to Build Your Own Infrared Sauna (Complete DIY Guide)

Building an infrared sauna is one of the best home wellness investments you can make.

Unlike traditional steam saunas, infrared saunas use far infrared radiation to heat the body directly—providing a comfortable, energy-efficient experience.

This guide covers:

  • Infrared sauna parts and components

  • Electrical and wiring requirements

  • Control system importance

  • Heater panel selection

  • DIY installation steps

  • Cost breakdown

  • Safety considerationsExpert sauna repair and maintenance solutions for control panels, heating elements, and accessories. Professional-grade parts and technical support for residential and commercial sauna

Infrared Sauna Components (What You Need)

A functional infrared sauna consists of three core systems:

  • Wood structure (enclosure)

  • Heating system (heater panels)

  • Control and electrical system

When designed correctly, these components work together to deliver consistent heat and reliable operation.

Where to Build Your Infrared Sauna

Infrared saunas do not require drainage or steam ventilation.

Common installation locations:

  • Basement

  • Garage

  • Home gym

  • Unused room

  • Enclosed patio

Requirements:

  • Dedicated electrical circuit

  • Level floor

  • Air circulation clearance (2 inches minimum)

  • Dry environment

Avoid high-humidity locations to extend material and electrical longevity.

Recommended Dimensions (DIY Infrared Sauna Sizes)

  • Single person: 36” x 36”

  • Two person: 48” x 48” or 48” x 60”

  • Height: 75” – 78”

Higher ceilings waste energy and reduce heat efficiency.

Wood Material Selection

Best materials:

  • Western red cedar (premium)

  • Canadian hemlock (value)

  • Spruce (budget option)

Avoid:

  • Pine (resin and odor)

  • Composite boards (heat emissions)

Infrared Heater Panels (Heating System)

Heating panel placement:

  • Back wall (40% power)

  • Side walls (40% power)

  • Lower leg area (10–20%)

Recommended total power:

  • Single person: 1200W – 1600W

  • Two person: 1800W – 2400W

We offer professional heater kits:

👉 Full Spectrum Infrared Sauna Heating Kit

Combining carbon fiber and full spectrum heaters provides even heat distribution and enhanced wellness benefits.

Electrical Requirements (Safety First)

Infrared saunas require dedicated circuits.

Common configurations:

  • 120V 20A (up to ~2000W)

  • 120V 30A (up to ~2800W)

  • 240V systems (larger builds)

Safety rule:

Use only 80% of circuit capacity for continuous operation.

Example:

  • 20A circuit → ~1600W continuous

  • 30A circuit → ~2400W continuous

Always consult a licensed electrician for wiring and breaker installation.

Control System Importance

The control system is the brain of your sauna.

Functions include:

  • Temperature regulation

  • Timer control

  • Safety shutdown

  • Power distribution

Never attempt to replace only internal components such as relays or boards.

Electrical systems must be matched for compatibility.

We provide complete control systems:

👉 Sauna control panel + power output box kits

These systems ensure safe and reliable operation.
