Sauna Parts You Should Know: Heaters, Stones, Panels & Controls

Investing in a home sauna is an investment in your longevity. Whether you are browsing our Indoor Sauna collection for a cozy corner unit or eyeing a spacious 4-person outdoor sauna, understanding the anatomy of the machine is crucial. A sauna is more than just a wooden box; it is a finely tuned system of components working together to deliver that perfect, detoxifying heat.

At Collective Relaxation, we believe an informed buyer is a happy owner. In this guide, we break down the critical parts of both traditional and infrared saunas—from the heart of the heat to the brain of the operation—so you can choose the right personal sauna for your wellness journey.

The Heart: Sauna Heaters

The heater is the engine of your sauna. Without it, you just have a closet. The type of heater you choose defines the entire experience.

1. Traditional Electric Heaters

Found in most classic indoor sauna and outdoor sauna models, these use electric coils to heat a compartment of stones.

• Pros: They can reach higher temperatures (185°F+) and allow you to create steam (löyly) by pouring water on the rocks.
• Best For: Purists who want the intense, humid heat of a Finnish-style sauna.

2. Infrared Panels (Carbon vs. Ceramic)

Modern 2 person sauna kits often use infrared technology, which heats your body directly rather than the air.

• Ceramic Rods: These heat up fast and get very hot, but the heat is concentrated near the heater.
• Carbon Fiber Panels: These large, flat panels distribute heat more evenly. They are more energy-efficient and emit a gentler, deeper-penetrating heat.
• Best For: Those seeking detoxification and muscle relief at lower, more tolerable temperatures (120°F-140°F).

The Soul: Sauna Stones

If you choose a traditional heater, the stones are not just decoration. They are thermal batteries.

• Igneous Rocks (Peridotite, Vulcanite): These are the gold standard. They are dense, rough-surfaced, and can withstand extreme thermal shock (rapid heating and cooling) without exploding.
• Ceramic Stones: While uniform, they often lack the thermal mass of natural rock and cool down faster when water is applied.
• Why It Matters: Good stones hold heat, keeping the sauna hot even when the electric elements cycle off. This creates a smooth, consistent "soft heat" rather than a harsh, dry burn.

The Brain: Control Panels

Gone are the days of simple egg timers. Modern control panels are the command center of your personal sauna.

1. Analog Controls

Simple dials usually located on the heater itself.

• Pros: Bombproof reliability. No software to crash.
• Cons: Less precise; you can't set an exact degree.

2. Digital & Smart Controls

Touchscreens mounted on the exterior wall.

• Features: Precise temperature setting, session timers, and control over lighting (chromotherapy) and Bluetooth audio.
• Smart Tech: Some high-end Outdoor Saunas now feature Wi-Fi controls, allowing you to pre-heat your sauna from your phone while driving home from work.

The Body: Wood & Insulation

While not a "mechanical" part, the wood choice is a critical component of the sauna system.

• Hemlock: Affordable, hypoallergenic, and resistant to warping. Common in indoor infrared kits.
• Red Cedar: The premium choice. It is naturally resistant to rot and insects (perfect for outdoor saunas) and reflects heat efficiently, keeping the energy bills down.

FAQs About Sauna Parts

Q: Can I replace a ceramic heater with a carbon fiber panel?
A: generally, no. The electrical requirements and mounting systems are different. It is best to choose the heater type you want when buying the sauna kit.

Q: How often should I replace sauna stones?
A: For home use, check them once a year. Discard any that have crumbled or cracked, as small pieces can block airflow in the heater and cause it to overheat.

Q: Do infrared saunas need stones?
A: No. Infrared saunas use panels to emit light waves. Stones are only for traditional stove-style heaters.

Q: Can I put a traditional heater in an infrared sauna?
A: We don't recommend it. Infrared cabins are often insulated differently and may not be built to withstand the high humidity and steam of a traditional heater.

Q: What is the best heater for a 2 person sauna?
A: For infrared, look for "Full Spectrum" carbon heaters to get the maximum health benefits. For traditional, a 4.5kW electric heater is usually sufficient for a compact 2-person space.

Know Your Machine

A sauna is a simple pleasure, but it relies on quality components to function safely and effectively. Whether you prioritize the steam capacity of igneous rocks or the even heat of carbon fiber panels, understanding these parts ensures you get the best personal sauna for your home.
