How to Choose the Right Outdoor Sauna for Your Backyard

Buying Your First Outdoor Sauna? Here's What Actually Matters

An outdoor sauna is one of the most rewarding things you can add to your backyard — but it's also a serious investment, usually somewhere between $5,000 and $10,000 or more when all is said and done. With that kind of money on the line, the last thing you want is to spend a weekend digging through conflicting blog posts and forum rabbit holes trying to figure out what you actually need.

This guide is different. We're going to walk you through six real decisions you'll need to make, with honest advice on what matters and what's just marketing fluff. By the end, you'll know exactly what to look for — and what to avoid.

Step 1 — Decide on Sauna Type: Traditional vs. Infrared

This is the first fork in the road, and it's worth getting clear on before anything else.

Traditional (Finnish-style) saunas use an electric or wood-burning heater to heat a pile of rocks, which then radiate heat throughout the room. You can ladle water over the rocks to create bursts of steam — called löyly — which intensifies the heat and gives you that classic sauna experience. Temperatures typically run between 150°F and 190°F.

Infrared saunas work differently. Instead of heating the air, infrared panels emit light waves that warm your body directly. They operate at lower temperatures — usually 120°F to 150°F — which some people prefer, especially those who find high heat overwhelming.

For outdoor use, traditional saunas have a clear advantage. They're built to handle temperature extremes, work efficiently in cold weather, and are far more structurally suited to outdoor placement. All LeisureCraft saunas — the brand we carry at LEXLETIX — are traditional Finnish-style, which is exactly what you want if the sauna is going outside.

Step 2 — Figure Out Your Space

Before you fall in love with a particular model, take measurements. Walk around your yard, patio, or deck and get realistic about what space is actually available. A few things to keep in mind:

• Clearance matters. You'll want at least 18–24 inches of clearance around the sauna for airflow and easy access if you ever need to do maintenance or refinishing.
• Think about the walk. You'll be making that trip from your back door to the sauna in a towel — possibly barefoot, possibly in the dark. A clear, safe, short path is a quality-of-life thing you'll appreciate every single session.
• Shape vs. footprint. Barrel saunas like the Canadian Timber Harmony have a smaller footprint and can tuck into tighter spaces. Cabin-style saunas like the Canadian Timber Luna need a bit more room but offer a roomier, more traditional interior.
• Electrical access. You'll need a dedicated 240V circuit run to wherever the sauna will sit. Think about how far that run is from your electrical panel — the longer the run, the more the electrician bill climbs.

Step 3 — Choose Your Size (How Many People?)

Sauna size is really a question of how you plan to use it, not just how many bodies can technically fit inside.

If you're buying mostly for solo sessions or occasional use with a partner, a 2-person model is efficient, heats up quickly, and won't cost much to run. For families, a 4-person model hits a sweet spot between space and practicality. If you're the kind of person who hosts and wants the sauna to be a social experience, a 6-person or larger model makes sense — though it will take longer to heat and cost more in electricity over time.

One thing people consistently underestimate: bigger isn't always better. A larger sauna that takes 45 minutes to reach temperature is going to get used a lot less than a compact one that's ready in 20. Think about your realistic, everyday use — not your best-case scenario.

For a look at what a compact but well-designed sauna looks like, check out the Canadian Timber MiniPOD — it's a great example of small done right.

Step 4 — Wood Type Matters More Than You Think

Outdoor saunas deal with rain, UV exposure, temperature swings, and constant moisture cycling — so the wood selection is critical, not cosmetic.

• Eastern White Cedar is the gold standard for outdoor saunas. It's naturally rot-resistant, handles moisture beautifully, and has that unmistakable aromatic quality that makes a sauna session feel like the real thing. LeisureCraft builds with Eastern White Cedar, and it shows in how well their saunas age outdoors.
• Red Cedar is similar in durability and also excellent, with a slightly darker, richer tone.
• Hemlock is a more affordable option — lighter in color and less aromatic, but still solid for outdoor use when properly maintained.
• Pine and spruce are common in budget kits, but they're softer woods that don't handle prolonged outdoor exposure as gracefully. They can work, but you'll need to be more diligent about sealing and maintenance.

If you're spending serious money on an outdoor sauna, don't cut corners on the wood. It's the thing that's going to be sitting outside in all weather, year after year.

Step 5 — Pick Your Heater

The heater is the heart of a traditional sauna, so it deserves real consideration.

Electric heaters are the most practical choice for most homeowners. They're clean, easy to control (often with digital timers so the sauna is pre-heated when you get home), and widely available. For most home saunas, you're looking at a 6–9 kW heater depending on the size of the room.

Wood-burning heaters give you the most authentic experience and don't require an electrical hookup — but they need more attention. You'll be managing a fire, dealing with ash, and making sure there's a proper flue. If you're going off-grid or just love the ritual, it's worth it. For most suburban backyards, electric is the more practical call.

Quality heater brands to look for include Harvia, HUUM, and Homecraft. LeisureCraft pairs each of their sauna models with a heater matched to that room's volume, which takes a lot of the guesswork out of it.

Step 6 — Consider the Total Cost, Not Just the Sticker Price

Here's where people often get surprised. The sauna kit is just the starting point.

• The sauna itself: $5,000–$10,000 for a quality outdoor model
• Electrical work: A licensed electrician running a dedicated 240V circuit typically runs $500–$1,500, depending on your panel location and how far the run is
• Site prep: You'll need a level, stable surface — gravel pad, concrete, or pavers. Budget $200–$1,000 depending on what your yard needs
• Accessories: Bucket and ladle, thermometer, hygrometer, sauna lighting, backrests — figure $100–$500 to do it right
• Ongoing costs: Electricity runs roughly $10–$30/month with regular use, which is genuinely minimal for what you're getting

One cost that catches people off guard: shipping. Outdoor saunas are heavy, freight-shipped items, and delivery charges can easily add $300–$600 if you're not buying from a dealer that includes it. At LEXLETIX, we offer free shipping on all our LeisureCraft saunas — that's a real difference in your final number.

Red Flags When Shopping for an Outdoor Sauna

The outdoor sauna market has grown fast, and not every seller is worth your trust. Here are the warning signs to watch for:

• No clear manufacturer info. If you can't figure out who actually built the sauna, that's a problem. Reputable brands are transparent about where and how their products are made.
• Prices that seem too good. A quality outdoor sauna costs what it costs because good wood, proper engineering, and durable hardware aren't cheap. If a "6-person cedar sauna" is listed for $1,800, you're not getting cedar — or a sauna that will last.
• Vague or missing warranty. A well-built outdoor sauna should come with a real structural warranty. If the seller can't tell you exactly what's covered and for how long, walk away.
• Stock photos only. Real products have real photos. If every image looks like it came from a catalog and you can't find reviews or owner photos, be cautious.
• No customer support. You'll have questions during assembly and setup. If there's no real person to contact, that's a preview of what happens if something goes wrong after delivery.

Buying from an authorized dealer ensures you get the actual manufacturer warranty, genuine materials, and a real contact if anything needs to be addressed.

Frequently Asked Questions

How much does an outdoor sauna cost?

A quality outdoor sauna kit typically runs between $5,000 and $10,000 or more, depending on size, wood type, and included features. Beyond the kit, budget an additional $500–$2,000 for electrical installation and site preparation. It's a real investment, but one that pays off in daily use for years.

Do I need a permit to install an outdoor sauna?

It depends on where you live. Many residential areas don't require a permit for a standalone outdoor sauna on private property, but local building codes and HOA rules vary. Before you commit to a placement, it's worth a quick call to your city's building department and a review of your HOA documents if applicable.

How long does it take to assemble an outdoor sauna?

Most LeisureCraft ready-to-assemble kits can be completed in one to two days with two people. The pieces are pre-cut and the instructions are clear — no specialized tools or carpentry experience required. The electrical hookup is the one step where you'll want a licensed electrician involved.

Can I use an outdoor sauna in winter?

Yes — and honestly, winter is when many people enjoy it most. There's something uniquely satisfying about stepping into a hot sauna when it's cold outside. LeisureCraft's Eastern White Cedar construction is designed for exactly this kind of year-round, all-weather use. The wood handles temperature swings well, and a quality heater will bring the room up to temperature even on cold days.
