Infrared and steam saunas differ significantly in their energy use, materials, and environmental impact. Infrared saunas are more energy-efficient, cost less to operate, and require no water, making them a greener choice. Steam saunas, while traditional, consume more energy and water and need frequent maintenance. Here's a quick comparison:
Quick Comparison
| Factor | Infrared Sauna | Steam Sauna |
|---|---|---|
| Energy Use | Low (1.5-3.0 kW/session) | High (6.0-9.0 kW/hour) |
| Water Usage | None | Requires continuous supply |
| Operating Cost | ~$10/month (3 sessions/week) | $20+/month (3 sessions/week) |
| Materials | Sustainable, recyclable wood | Moisture-resistant wood, rocks |
| Maintenance | Minimal | Frequent cleaning and upkeep |
| Environmental Impact | Lower | Higher |
Infrared saunas are ideal for those prioritizing energy efficiency and low resource usage, while steam saunas may appeal to traditionalists despite their higher environmental costs.
Energy Efficiency: Infrared vs Steam Saunas
Infrared saunas are known for using less energy compared to traditional steam saunas. This not only helps save money but also reduces the environmental impact of using a home sauna.
Infrared Saunas: Energy Consumption
Infrared saunas typically have power ratings between 1,000 and 3,000 watts and heat up in just 10-15 minutes. For example, running a 1.9KW infrared sauna for three one-hour sessions each week costs around $2, assuming an electricity rate of 30 cents per kWh.
Steam Saunas: Energy Requirements
Steam saunas, on the other hand, need more energy to heat the space (70-85°C), produce steam, and compensate for heat lost through ventilation. A standard 6kW steam sauna heater used for one hour, three times a week, consumes about 6.0 kWh per session.
Energy Usage Comparison Table
| Feature | Infrared Sauna | Steam Sauna |
|---|---|---|
| Power Rating | 1.5-3.0 kW | 6.0-9.0 kW |
| Heat-up Time | 10-15 minutes | 30-40 minutes |
| Operating Temperature | 46-57°C | 70-85°C |
| Monthly Energy Cost* | $10 (3 sessions/week) | $20+ (3 sessions/week) |
| Annual Operating Cost** | $300-400 | $500-600 |
*Based on average U.S. electricity rates of $0.13 per kWh
**Varies depending on usage and local electricity rates
To get the most out of your sauna while keeping costs down, consider using it during off-peak hours, ensuring proper insulation, performing regular maintenance, and turning it off immediately after use.
Expert Manny Brambila states, "The convenience of having a sauna in your own home or garden is undeniable, but it's crucial to factor in the ongoing expenses involved" [3]. This makes it essential to evaluate both long-term costs and the environmental impact.
Besides energy efficiency, the choice of materials used in the sauna also plays a role in its overall environmental footprint.
Material Sustainability and Recyclability
Saunas impact the environment not just through energy use but also through the materials they’re made of and how recyclable those materials are. While energy efficiency helps with day-to-day operations, the materials used in construction influence the overall environmental footprint over a sauna's lifetime.
Materials in Infrared Saunas
Infrared saunas are typically made from wood, metal, and plastic. Their heating panels, which last about 8-10 years, are recyclable through standard facilities, helping reduce landfill waste. Many use sustainably sourced wood, often certified by the FSC, ensuring responsible forestry practices. Plus, the low moisture exposure in infrared saunas helps extend the lifespan of their components.
Materials in Steam Saunas
Steam saunas, on the other hand, use wood and heating rocks. However, the constant moisture accelerates wood wear and tear. The heating rocks also need to be replaced every 1-2 years, which increases material usage over time.
Material Sustainability Comparison Table
| Component | Infrared Sauna | Steam Sauna | Environmental Impact |
|---|---|---|---|
| Primary Structure | Sustainably sourced wood | Moisture-resistant wood | Moderate - depends on sourcing |
| Heating Elements | Recyclable panels (8-10-year lifespan) | Metal heater + rocks (1-2-year replacement) | Lower for infrared |
| Additional Materials | - | Requires regular rock replacement | Higher for steam |
| End-of-Life Recyclability | High - most components recyclable | Moderate - moisture damage limits recyclability | Lower impact for infrared |
| Maintenance Requirements | Low - minimal material replacement | High - frequent updates needed | Higher impact for steam |
Regular maintenance can help prolong the life of materials, reducing the need for replacements and lowering the overall environmental footprint. Along with materials, factors like water usage and upkeep also significantly affect a sauna's impact on the planet.

Resource Usage: Water and Maintenance
Water Usage in Steam Saunas
Steam saunas rely heavily on water to operate. Beyond producing steam, they also need water for regular cleaning to prevent mold and maintain hygiene. This frequent use of water adds to their overall resource consumption and environmental impact.
Infrared Saunas: No Water Needed
Infrared saunas operate without requiring any water. This makes them a resource-efficient option, especially for those looking to reduce their environmental footprint. With no water involved, they also avoid moisture-related maintenance issues.
Maintenance Impact
The maintenance demands of steam and infrared saunas differ greatly. Steam saunas need regular cleaning and frequent component replacements due to constant exposure to moisture. This not only increases upkeep efforts but also contributes to material wear over time. On the other hand, infrared saunas require minimal maintenance, which translates to fewer resources used in the long run.
| Maintenance Aspect | Steam Sauna | Infrared Sauna | Environmental Impact |
|---|---|---|---|
| Cleaning Frequency | Daily/Weekly deep cleaning | Basic periodic cleaning | Higher for steam |
| Water Requirements | High for operation/cleaning | None | Higher for steam |
| Component Replacement | Frequent due to moisture | Minimal | Higher for steam |
| Lifetime Resource Usage | High (water, supplies) | Low | Higher for steam |
Steam saunas demand more than just water - they also require ongoing humidity control and surface upkeep, which leads to greater resource use over time [1]. Infrared saunas, by contrast, need only occasional cleaning, avoiding the complications of moisture and reducing both costs and environmental impact [1].
For an even greener option, infrared saunas can be powered using renewable energy sources like solar panels [2]. This pairing of low-maintenance operation with renewable energy makes them an appealing choice for those prioritizing sustainability. By comparing these factors, consumers can choose a sauna that aligns with their wellness goals while being mindful of resource use and environmental considerations.
Choosing an Eco-Friendly Sauna
When it comes to minimizing environmental impact, the type of sauna you choose makes a big difference. By looking at energy use, materials, and resource demands, it's clear that not all saunas are created equal.
Comparing Infrared and Steam Saunas
Infrared saunas stand out as the greener option. Steam saunas consume significantly more energy - about 6-8kW per hour to keep rocks heated [1]. Infrared models, on the other hand, use focused heating, which cuts down on energy waste.
Another advantage? Infrared saunas often incorporate wood from sustainable sources, like reforested Canadian hemlock [4]. They also don’t require water, which lowers their overall resource demands. Steam saunas, however, need a continuous water supply and regular upkeep, adding to their environmental cost over time.
Infrared saunas also pair well with renewable energy setups, such as solar panels, making them a practical choice for reducing your carbon footprint [2]. By understanding these distinctions, you can choose a sauna that aligns with both your wellness and sustainability goals.
