Choosing the right sauna heater starts with understanding your space, control preferences, and budget. Here's what to consider:

1. Calculate Your Sauna Room Size
The size of your sauna determines the heater size you need.

• Step 1: Measure the room’s volume (Length × Width × Height in feet).

• Step 2: Match that volume to the heater's power rating (measured in kilowatts).

• Choosing the correct size ensures fast heat-up times and consistent warmth.

2. Consider Control Options
How you control your sauna experience is just as important:

• Built-in controls: Simple and cost-effective, ideal for small or personal saunas.

• Digital wall controls (e.g., SL2): Sleek, easy-to-use, and placed outside the sauna for convenience.

• Wi-Fi enabled controls: Control your sauna remotely with your smartphone—perfect for preheating before you step in.

3. Factor in Your Budget
We offer sauna heaters at a variety of price points, from practical and affordable models to premium options with advanced features. No matter your budget, there’s a reliable heater to match your needs.

Choosing the right size electric sauna heater is key to achieving efficient, consistent heat and a comfortable sauna experience. Here’s how to find the right fit:

1. Calculate Your Sauna Volume
Measure your sauna’s Length × Width × Height to get the total volume in cubic feet (ft³) or cubic meters (m³). This tells you how much power your heater needs.

2. Check Heater Specifications
Sauna heaters models are based on their kilowatt (kW) capacity, which determines how much space they can effectively heat. Each heater model includes specifications indicating the ideal room volume it can handle. Be sure to compare your sauna’s size with the manufacturer’s guidelines to find a properly matched unit.

3. Adjust for Heat Loss
If your sauna includes glass doors, stone walls, or other non-insulated materials, consider increasing your heater size by 10–20% to offset heat loss.

Tip: It’s often best to size slightly up—this ensures faster heat-up times and better overall performance.
