The Complete Sauna Buying Guide

Buying a home sauna is one of the most rewarding wellness investments you can make — but it's also one of the most nuanced. The right sauna depends on how you plan to use it, where you'll install it, how many people will use it, and what kind of heat experience you're after. At Iridescent Home, we've helped hundreds of customers find their perfect sauna across our full lineup of infrared, traditional, and barrel models. This guide covers everything you need to make a confident, informed decision.

Step 1: Choose Your Sauna Type

Infrared Saunas Infrared saunas use light-based heating panels to warm your body directly rather than heating the surrounding air. The cabin temperature runs cooler (120–150°F) but the penetrating radiant heat creates an effective, deep sweat at a temperature that's comfortable for most people — even those who struggle in traditional high-heat environments. Best for: Muscle recovery, chronic pain relief, skin health, daily sessions, beginner sauna users, smaller indoor spaces, plug-and-play installation.

Traditional (Finnish) Saunas Traditional saunas use an electric heater or wood-burning stove to heat the cabin to 160–210°F. Pouring water over hot sauna stones creates bursts of steam ("löyly") — the defining ritual of authentic sauna culture. The intensity is higher, the warm-up takes longer (30–45 min), and installation requires 240V wiring, but the experience is unmatched. Best for: Authentic sauna culture enthusiasts, high-heat preference, steam ritual (löyly), cardiovascular conditioning, social sauna sessions with multiple people.

Barrel Saunas Barrel saunas are round, outdoor-style saunas built from premium cedar. The cylindrical shape improves heat circulation, reduces the air volume that needs to be heated (faster warm-up), and makes a stunning visual statement on any deck, patio, or backyard. These use traditional electric heaters and include sauna stone compatibility. Best for: Outdoor installation, backyard aesthetics, year-round outdoor use, traditional heat experience in a weather-resistant design.

Step 2: Determine the Right Size

Sauna size is measured in person capacity — but the right number isn't always the number of people who'll use it at once. Consider:

• 1-2 Person: Compact, space-efficient, lower energy use. Ideal for solo daily practitioners or couples. Works in most indoor spaces including large closets, spare bedrooms, or garages.
• 3-4 Person: The most popular size for families. Spacious enough for 2 people to sit comfortably with room to stretch out. Fits in a dedicated sauna room or large bathroom.
• 5-6 Person: Large-format for families or those who regularly entertain. Requires adequate dedicated space. Delivers a near-commercial sauna experience at home.

A good rule of thumb: go one size larger than you think you need. The extra room allows you to lie down, stretch, and use the sauna more comfortably — which means you'll use it more often.

Step 3: Choose Your Wood

• Canadian Hemlock: Light-colored, non-aromatic, hypoallergenic, and dimensionally stable under heat. The most popular wood for infrared saunas.
• Western Red Cedar: The gold standard for traditional and barrel saunas. Naturally rot-resistant, aromatic, and beautiful. Holds up exceptionally well to moisture and outdoor conditions.
• Nordic Spruce: Used in premium Finnish-style saunas. Dense, durable, and traditionally authentic. Turns golden with age.
• Basswood: Very light, smooth, and nearly white. Low resin content makes it ideal for those with wood allergies.

Step 4: Understand Heater Technology

Infrared Heaters: Near, Mid & Far Full-spectrum infrared saunas incorporate all three wavelengths for maximum benefit. Far infrared is the most studied for detoxification and deep tissue penetration. Mid infrared supports circulation. Near infrared promotes cellular repair and skin health. Look for full-spectrum or carbon/ceramic far-infrared panels for the best performance.

Traditional Electric Heaters Traditional sauna heaters are rated in kilowatts (kW) — generally 1 kW per 50 cubic feet of cabin volume is the baseline. Look for stainless steel housing, a large stone capacity (more stones = more stable heat and better steam), and safety shutoff timers. All traditional heaters in our lineup require 240V dedicated circuits.

Step 5: Plan Your Installation

Indoor Infrared Saunas: Most models in our infrared lineup plug into a standard 120V outlet. Assembly takes 2–4 hours with two people and basic tools. No special ventilation or flooring is required — just a level surface and adequate clearance around the unit.

Indoor Traditional Saunas: Require a 240V dedicated circuit (installed by a licensed electrician). Allow for ventilation near the floor to maintain proper airflow. A vapor barrier between the cabin wall and room wall is recommended.

Outdoor Barrel Saunas: Place on a level, stable foundation — concrete pavers, a wood deck, or a gravel pad all work. Require a 240V outdoor-rated circuit. Our barrel saunas ship with weather-resistant cedar that handles freeze-thaw cycles and rain without deterioration.

Step 6: Set Your Budget

• Entry-level infrared (1-2 person): $800–$1,500 — solid for solo daily use, basic panel technology
• Mid-range infrared (2-4 person): $1,500–$3,500 — full-spectrum panels, chromotherapy, Bluetooth audio, premium wood
• Premium infrared or traditional (4-6 person): $3,500–$7,000+ — medical-grade panels, luxury finishes, extended warranties
• Barrel saunas: $2,500–$6,000 — outdoor cedar construction, traditional electric heater, sauna accessories included

Consider total cost of ownership: infrared saunas cost approximately $0.25–$0.50 per session in electricity. Traditional saunas run higher due to longer heat-up time and higher operating temperatures.
