Saunas With Built-In Red Light Therapy

Red light therapy saunas combine infrared sauna heating with built-in red and near-infrared light therapy panels, giving you two science-backed wellness treatments in a single session. While the infrared heaters warm your body and promote sweating at 120–150°F, the red light panels deliver targeted wavelengths (typically 630–660nm red and 810–850nm near-infrared) that penetrate skin and tissue to support collagen production, muscle recovery, circulation, and cellular repair. 

We carry red light therapy saunas from Dynamic Saunas, Golden Designs, Maxxus, Finnmark Designs, and Wizzisaunas. Every order ships free with 0% APR financing. Already own a sauna? You can also add red light therapy panels to your existing sauna — browse our standalone red light panels for saunas.

How Red Light Therapy Works in a Sauna

Red light therapy (also called photobiomodulation) uses specific wavelengths of visible red and near-infrared light to stimulate cellular energy production. The light penetrates skin and tissue, where it's absorbed by mitochondria — the energy-producing structures in your cells — and triggers increased production of ATP (adenosine triphosphate), the molecule your cells use for energy. This process supports tissue repair, reduces inflammation, and accelerates recovery.

In a red light therapy sauna, the red light panels are mounted alongside the infrared heating panels on the interior walls. You get both treatments simultaneously: the infrared wavelengths (typically 5.6–15 microns for FAR, plus near and mid for full spectrum) warm your body from within, while the red and near-infrared light wavelengths (630–850nm) target your skin and surface tissue. The two technologies use completely different parts of the light spectrum and work through different biological mechanisms, so they complement rather than duplicate each other.

For a deeper explanation of how these wavelengths differ, read our guide on red light vs. infrared light therapy — what's the difference.

Built-In Red Light vs. Add-On Panels

Saunas with built-in red light — The red light panels are factory-installed into the sauna cabin and wired into the same control system. This means optimal panel placement, no extra setup, and a cleaner look. Brands like Dynamic Saunas, Golden Designs, Maxxus, Finnmark Designs include medical-grade red light as standard equipment. Built-in models cost more upfront but deliver the most integrated experience.

Add-on red light panels — Standalone panels that you mount inside your existing sauna (infrared, traditional, or hybrid). This is the more affordable route if you already own a sauna and want to add red light capability without buying a new unit. Products like the Haven Of Heat Red Light Panel and SaunaPro panels are rated for the high heat and humidity inside a sauna (not all red light panels are — regular panels can overheat and fail). Our guide on how to add red light to your sauna covers sizing, placement, and installation.

Shop by Brand

Dynamic Saunas — North America's best-selling infrared sauna brand, with red light therapy (662.7nm) available across all three technology tiers. The Elite line (ultra low EMF FAR infrared) includes models like the Lucca Elite (2-person), Veneto Elite (1–2 person), Toscana Elite (3-person), and Versailles Elite (2-person). The Full Spectrum line (near + mid + FAR infrared with near-zero EMF) pairs the broadest infrared coverage with red light — standouts include the Gracia FS (1–2 person), Santiago FS (2-person), Martin FS (1–2 person), and Vila Grande FS (4-person). Even Dynamic's standard Low EMF models like the Gracia and Veneto include integrated red light therapy at the most affordable price points. All Dynamic saunas are built from Canadian hemlock.

Maxxus Saunas — A wide range of infrared saunas with built-in red light therapy (662.7nm) across multiple size and EMF tiers. The S-Line is the flagship, available in 1-person through 3-person sizes in Low EMF, Ultra Low EMF Elite, and Full Spectrum Near Zero EMF configurations — all with red light. The S-Line 2-Person Full Spectrum combines near-zero EMF full spectrum infrared with red light therapy in Pacific Cedar, while the S-Line 1-Person is one of the most compact red light saunas available. Beyond the S-Line, Maxxus offers red light across their K-Series and corner models in sizes from 2 to 4 people, in both Canadian Hemlock and Red Cedar construction.

Golden Designs — Golden Designs (parent company of Dynamic and Maxxus) offers red light therapy across their infrared, hybrid, and traditional sauna lines. Their Reserve Edition full spectrum infrared saunas include red light therapy and a Himalayan salt bar in sizes from 1–2 person to 3-person and 4-person. Their hybrid saunas — which combine full spectrum infrared with a Harvia traditional electric heater — also include red light, with indoor models like the Toledo (6-person) and Soria (3-person), plus outdoor versions like the Karlstad (6-person) and Nora (2-person). Even Golden Designs' traditional saunas like the Kuusamo (6-person) include a red light therapy feature.

Wizzisaunas — A newer brand offering outdoor and indoor infrared saunas with red light therapy. The Wizzisaunas 909MX is a 1-person full spectrum near-zero EMF indoor infrared sauna with medical-grade red and blue light therapy — one of the few models on the market to include both red and blue light wavelengths. The VF04 is a 4-person outdoor FAR infrared sauna built from maintenance-free WPC (Wood-Plastic Composite) with 120V plug-and-play power, designed for all-weather use.

Finnmark Designs — Full spectrum infrared saunas with a premium Nordic design. Finnmark's saunas can be configured with red light panels and are compatible with their WiFi touchscreen controller. Their hybrid model combines full spectrum infrared, a traditional electric heater, and red light capability in one unit.

Indoor vs. Outdoor Red Light Saunas

Indoor Red Light Saunas — Most red light therapy saunas are designed for indoor use. They're freestanding cabins that fit in bedrooms, basements, bathrooms, and garages. Many 1–2 person models plug into a standard 120V outlet. This is where the widest selection is.

Outdoor Red Light Saunas — Fewer pre-built options exist for outdoor red light saunas. The most practical approach for outdoor setups is to buy an outdoor sauna (barrel, cabin, or cube) and add sauna-rated red light panels inside. The panels need to be rated for high temperature and humidity.

Red Light Therapy Sauna vs. Infrared Sauna — What's the Difference?

All red light therapy saunas are infrared saunas, but not all infrared saunas include red light. A standard infrared sauna uses FAR infrared or full spectrum infrared panels to heat your body. A red light therapy sauna adds dedicated red/near-infrared light panels (630–850nm) that target skin and surface tissue through a different biological mechanism (photobiomodulation). The infrared heaters and the red light panels operate independently — you can run them together or separately.

If you're choosing between the two: a standard infrared sauna is more affordable and delivers the core sauna experience (sweating, relaxation, circulation). Adding red light therapy costs more but gives you additional skin health, recovery, and anti-inflammatory benefits. For a full comparison, read our guide on infrared saunas vs. red light therapy.

Add Red Light to Any Sauna

You don't need to buy a new sauna to get red light therapy. Our sauna-rated red light therapy panels are designed to withstand the heat and humidity inside any sauna — infrared, traditional, or hybrid. Mount them on the wall, plug them in, and you've got red light capability in your existing setup.

The Haven Of Heat Red Light Panel is our most popular add-on option, and the SaunaPro 40" x 10" panel offers a larger coverage area. Both are rated for sauna temperatures up to 200°F+. Our guide on adding red light to your sauna walks through everything — sizing, placement, wiring, and how to get the most out of combined sessions.

Frequently Asked Questions

What does red light therapy in a sauna actually do?

Red light therapy uses specific wavelengths (630–660nm red, 810–850nm near-infrared) to stimulate cellular energy production, support collagen synthesis, reduce inflammation, and accelerate tissue repair. In a sauna, you get these benefits alongside the circulation, detoxification, and relaxation benefits of infrared heat. The two treatments work through different mechanisms, so combining them gives you more than either alone.

Is a red light therapy sauna worth the extra cost?

If skin health, muscle recovery, or anti-inflammatory benefits are priorities for you, the extra cost is worthwhile — you're getting two treatments in the time of one. If you're primarily interested in sweating, relaxation, and general wellness, a standard infrared sauna delivers the core sauna experience at a lower price. You can always add red light panels later.

Can I add red light therapy to my existing sauna?

Yes — this is one of the most common upgrades. Mount sauna-rated red light panels on the interior walls of any sauna (infrared, traditional, or hybrid). Make sure the panels are specifically rated for high-temperature sauna use — regular red light panels from Amazon or consumer wellness brands will overheat and fail. See our step-by-step guide.

What's the difference between red light and infrared in a sauna?

Infrared sauna heaters use FAR infrared wavelengths (5.6–15 microns) to warm your body from within — this is what makes you sweat. Red light therapy uses visible red (630–660nm) and near-infrared (810–850nm) wavelengths to stimulate cellular repair at the skin and tissue level. They're completely different parts of the light spectrum doing different things. A red light therapy sauna includes both. For the full explanation, read our red light vs. infrared guide.

Do I need a full spectrum sauna for red light therapy?

No. Full spectrum refers to the infrared heating wavelengths (near, mid, and FAR infrared), which is separate from red light therapy. You can have a FAR-only infrared sauna with red light panels (like Dynamic's Elite line) or a full spectrum infrared sauna with red light (like Dynamic Saunas, Golden Designs, Maxxus). Full spectrum plus red light gives you the broadest range of wavelengths, but it's not required to get the benefits of red light therapy.

Can I use red light therapy with a traditional (steam) sauna?

Yes, as long as the red light panels are rated for high humidity. Products like the SaunaPro panel are specifically rated for steam sauna conditions. Mount them in your traditional sauna or hybrid sauna and you'll get red light benefits alongside the high-heat steam experience.

How do I build a DIY red light sauna?

Start with our DIY infrared sauna build guide, then add sauna-rated red light panels to the walls. You'll need infrared heater panels, a controller, red light panels, and sauna-grade wood. Use our infrared panel calculator for sizing the heating panels.
