Retrofit + DIY

Don't replace your sauna. Give it another way to heat.

If you already have a traditional sauna, infrared panels can often be added to the right wall and bench areas. The same sauna can keep its high-heat, steam-style ritual while also offering a quieter infrared experience when you do not want to bring the room up to traditional temperatures.

DIY hybrid sauna with infrared panels and wood benches

Built for three project types

Build a new DIY infrared sauna, upgrade an older traditional sauna, or add infrared use inside a traditional sauna room. The two systems should be planned as separate modes and used one at a time.

  • Plan infrared panels for wall, back, leg, and under-bench heating zones.
  • Use one room for traditional high heat or direct infrared warmth, depending on the session.
  • Add controls, lighting, audio, chromotherapy, and air purification as optional upgrades.
  • Estimate infrared wattage, current draw, and recommended voltage from room volume.

Hybrid Heat

Two sauna experiences. One room.

01

Traditional Mode

The sauna heater warms the air and stones for a 170-195°F high-heat session with the familiar steam ritual.

02

Infrared Mode

Infrared panels deliver direct warmth at lower room temperatures, making them useful for recovery, stretching, and shorter daily sessions.

03

Separate Switching

The traditional heater and infrared panels should be planned as two independent experiences. Do not run both systems at the same time.

Not sure if your existing sauna can be upgraded?

Email or text the inside dimensions, bench photos, and heater model. We can review the panel locations and estimated panel count.

    Start with room size, target use, and available power.

    Installation Notes

    The easy-to-miss details are panel placement and electrical capacity.

    Infrared panels should be placed where they can face the body. Traditional heaters require clearance, airflow, and heat-rated materials. A dual-experience sauna should have clear wiring, controls, and switching logic to avoid misuse or overload.

    FAQ

    Frequently Asked Questions

    Can a traditional sauna be upgraded with infrared panels?

    Often, yes. It depends on inside dimensions, bench layout, wall material, existing heater location, and available electrical capacity. Photos and measurements help us identify usable panel locations.

    Can the traditional heater and infrared panels run at the same time?

    No. This hybrid concept means one sauna room can offer two separate experiences. Choose traditional or infrared for a session, and use clear controls and wiring to reduce misuse.

    What are the benefits of adding infrared panels?

    Infrared mode can preheat faster, feel more direct, and work well for lower-temperature relaxation, post-workout recovery, and shorter daily sessions.

    Is the calculator wattage the final quote?

    No. The calculator is only a starting estimate. Final recommendations depend on glass area, insulation, panel size, control setup, power availability, and mounting locations.

    What parts do I need for a DIY infrared sauna?

    A typical DIY infrared sauna project needs infrared panels or heaters, a control system, wiring planned for the total wattage, sauna-safe wood, insulation, a vapor barrier, ventilation, lighting, and a bench layout that places panels near the body.

    What is a hybrid sauna?

    A hybrid sauna is one sauna room planned for two separate experiences: traditional high-heat sauna use and infrared panel use. The systems should be controlled separately and used one mode at a time.

    Can I convert a traditional sauna into an infrared sauna?

    Yes, many traditional wood saunas can be converted or upgraded with infrared panels. The best approach depends on panel placement, available wall space, bench layout, and the electrical service available to the sauna.

    How many infrared sauna panels do I need?

    The number of infrared panels depends on the room volume, panel wattage, insulation, glass area, and where people sit. A common starting point is estimating total infrared wattage first, then dividing that wattage across back, side, leg, and under-bench zones.

    How much wattage does a DIY infrared sauna need?

    Many DIY infrared sauna projects start around 12 to 15 watts per cubic foot, then adjust for insulation, glass, and room design. Larger or poorly insulated spaces may need more wattage for a comfortable infrared session.

    Do infrared sauna panels need 120V or 240V power?

    Small infrared sauna kits may work on 120V, but higher-wattage projects often make more sense on 240V. Always have a licensed electrician confirm circuit size, breaker capacity, wire gauge, and local code requirements.

    Where should infrared panels be installed in a sauna?

    Infrared panels work best when they face the body directly. Common locations include the back wall behind the bench, side walls, calf or leg areas, and under-bench zones depending on the room layout.

    Can infrared panels be installed behind sauna benches?

    Yes, back-wall and under-bench locations are common, but clearance, heat rating, mounting method, and protection from accidental contact all matter. Use components designed for sauna temperatures.

    What size room works best for a DIY sauna?

    Many home DIY sauna projects are built for one to four people, often in compact rooms where the bench layout, ceiling height, insulation, and heater placement can be controlled. Smaller rooms are usually easier to heat and easier to size accurately.

    Can I keep my existing sauna heater?

    In many retrofit projects, yes. The traditional heater can remain for traditional sauna sessions while infrared panels are added as a separate mode. The controls and electrical planning should make the two uses clear and separate.

    Do I need a new sauna control system?

    You may need a separate control system for the infrared panels, especially when adding panels to an existing traditional sauna. A dedicated control setup helps manage temperature, timer settings, and safer switching between modes.

    Are infrared sauna panels safe in a wood sauna?

    Infrared panels can be used safely in wood sauna rooms when they are properly rated, mounted with the correct clearances, wired correctly, and installed according to manufacturer instructions and local electrical code.

    Can I install a hybrid sauna kit myself?

    Some mounting and layout work may be suitable for skilled DIY installers, but electrical work should be completed or reviewed by a licensed electrician. Sauna heat, wood materials, and electrical load all need careful planning.

    Can I build a DIY infrared sauna in a spare room or basement?

    Yes, but the room must be planned for heat, moisture control, electrical load, ventilation, and sauna-safe interior materials. Basements, garages, closets, and spare rooms can work when the structure and wiring are reviewed first.

    Can I buy the infrared heaters and controls directly?

    Yes. You can shop infrared sauna heaters and sauna control systems directly from the product category links on this page. If you are not sure which parts fit your room, email or text your dimensions before ordering.

    What is the difference between a DIY sauna kit and a retrofit kit?

    A DIY sauna kit is usually planned for a new room build, while a retrofit kit adds infrared heaters, controls, and wiring to an existing sauna. Retrofit projects require extra attention to existing benches, heater location, clearances, and available circuits.

    Have your dimensions ready?

    Email or text dimensions and photos. We'll help estimate panel count, electrical needs, and installation direction.
