Infrared saunas range from around $1,200 to well over $4,500, and the sticker price is only part of the story. Here's a transparent breakdown of what a home infrared sauna actually costs in 2026 — including the ongoing costs most guides skip.
Upfront unit cost by size
- 1-person: roughly $1,200–$3,100. Entry point for a personal setup.
- 2-person: roughly $2,000–$2,900. The most popular size.
- 3-person: around $3,300 and up, often with full spectrum or reclining features.
- 4–5 person: roughly $4,300–$4,500+, typically outdoor models.
What drives the price within a size: wood type (cedar and mahogany cost more than hemlock), heater technology (full spectrum and Ultra-Low EMF add cost), and features like app control and chromotherapy.
Electricity — the ongoing cost
Infrared saunas are efficient because they run at lower temperatures than traditional saunas. Expect roughly $15–$30 per month with regular use, versus $30–$60 for a traditional sauna. Actual cost depends on your local electricity rate and how often you use it.
Installation
- Most 1–2 person units: $0 — they plug into a standard 120V outlet.
- Larger or premium units needing a dedicated circuit: roughly $200–$500 for an electrician.
- Outdoor saunas: may need a level foundation/pad and outdoor electrical access.
Accessories worth budgeting for
- Waterproof cover (outdoor): around $109–$199 — protects your investment.
- Towels, backrests, and cleaning supplies: minor.
Total cost of ownership example
A 2-person indoor sauna at ~$2,199, plugged into an existing outlet, using ~$20/month in electricity, costs about $2,199 upfront + ~$240/year to run. No installation, no cover needed indoors.
Is it worth it?
