Best Outdoor Sauna Overall: Sun Home Luminar Outdoor 5-Person Infrared Sauna

Our Thoughts on the Sun Home Luminar Outdoor 5-Person Infrared Sauna

The Sun Home Luminar Outdoor 5-Person Infrared Sauna is our pick for the best overall outdoor sauna because it balances performance, comfort, and design in a way that should satisfy most outdoor buyers, not just sauna enthusiasts. The five‑person capacity makes it more versatile than compact, single‑user units, yet its efficient infrared system helps keep warm‑up times reasonable and sessions comfortable across seasons. Its elevated build quality and feature set also make it feel like a long‑term investment, rather than a compromise you plan to upgrade in a few years.

Rachel tested this sauna and loved the sleek aesthetics and host of features that it brings. “The Luminar is big enough to host several of my friends and is very comfortable,” she said. “I also like that this particular sauna doesn’t need any coals and has a very fast start-up time for those mornings that you may only have 10-15 minutes to use it.”

This tester also loved the sauna’s tech perks. The audio system, Bluetooth connectivity, and LED display make it ideal for group settings, she added. Plus, you can even let another friend in your group take over the music controls from their phone. 

When it comes to temperature, this sauna maintains its heat very well. The initial start-up period took about 10 minutes to get to 130°F, and another 10 minutes to reach the goal temperature of 140°F. “It’s very easy to adjust the temperature of this sauna,” Rachel said. “Using the keypad, you can go back and forth between Celsius and Fahrenheit easily to set your ideal temperature, no matter which metric you use.”

Rachel rated the seating of the Luminar as a 5 out of 5, noting that it included ergonomic seating that fit her well. The seats were the right height, and not too close to the heat lamps. “The seating was also long enough to lie down, and stayed comfortable over a period of time,” she said.

The controls of this sauna were intuitive and easy to use. “The display clearly showed the temperature, the LED display, and the time duration,” Rachel said, rating it a 5 out of 5 in this category. “Figuring out the LED display was enjoyable and the sauna came with nine other modes to choose from, and I was able to switch throughout the modes during my testing,” she said.

Best Outdoor Infrared Sauna: Plunge Sauna

Our Thoughts on the Plunge Sauna

We chose the Plunge Sauna as our pick for the best outdoor infrared sauna because it includes advanced technology, superior craftsmanship, and everyday usability. It’s great for folks who see their outdoor space as an extension of their wellness routine and are looking to make an investment in long-term health, recovery, and relaxation.

Ellie tested the Plunge Sauna, rating the seating as a 4 out of 5. Though the standard size of this sauna states that it fits four to five people, Ellie thinks three people would be the max that could fit. She tested the sauna with another tall person, and as two people taller than 6 feet, found it a little cramped. “The top row would be better for people who are shorter than I am at 6 feet, 1 inch—however, you could fit multiple people,” Ellie said.

This sauna maintained its temperature very well. “It does take a long period to heat up, but once it got there, it stayed consistently warm throughout my time using it,” she said.

She rated her experience with the controls as a 5 out of 5, finding the controls very easy to use. “You use a simple dial to turn it on. I didn’t need any additional guidance or instructions to figure out how to use the sauna. I think it’s super user-friendly and universally understandable,” Ellie said.

Ellie loved the aesthetic appeal of the Plunge Sauna. “This sauna would look very attractive in your backyard,” she said. “The wood paneling looks very nice, and it’s a classy-looking sauna,” Ellie noted, rating it a 5 out of 5 in this category.

Best Outdoor Steam Sauna: Redwood Outdoors Duo Outdoor Sauna

Our Thoughts on the Redwood Outdoors Duo Outdoor Sauna

The Redwood Outdoors Duo Outdoor Sauna is our pick for the best outdoor steam sauna because it delivers a traditional sauna experience that’s approachable for home users. Its design encourages shared sessions for two and feels like a natural extension of a backyard retreat, rather than another piece of equipment. The combination of authentic steam, quality materials, and generous interior space makes it especially appealing for those who want a restorative heat experience.

Ryan tested this sauna and had a great experience, rating it as a 4 out of 5 overall. “For the price point, this sauna offered fewer options but ultimately did the same job as some of its more expensive competitors,” he said. “Though the other sauna I tried had a sound system and more heat lamps, this model is half the price and still offers a great aesthetic that would look great with any home.” He really loved the heat exposure and found it very comfortable.

While testing, Ryan ran the coals to the max setting and it reached a temperature of 130°F. “Using the temperature gauge in the sauna, I noticed that over the 15 minutes that I was testing it, the temperature dropped ten degrees by the end of the session,” he noticed.

After sitting in the unit, he rated the seating a 3 out of 5. “It was not the most comfortable seating, but I liked that there were multiple tiers of seating to accommodate several people. What was most uncomfortable with this sauna in comparison to the others I tested was that the seats were flat, benchlike, and did not have much back support,” Ryan said. During testing, he sat in different spots throughout the sauna, and noted that the upper tier had the most consistent heat delivery throughout the session.

Ryan liked the aesthetic appeal of this sauna, rating it a 4 out of 5. He enjoyed the rustic cabin look. “The glass doors and slotted windows make for an attractive product for folks to show to their houseguests,” he said. “The heater with the coals also looks sleek and attractive.”

Best Budget Outdoor Sauna: SAUNABOX Pulse Pro with Red Light

Our Thoughts on the SAUNABOX Pulse Pro

The SAUNABOX Pulse Pro is our pick for the best budget outdoor sauna because it has an appealing blend of price, performance, and versatility. Rather than feeling like a stripped-down option, it gives newer sauna users a genuine outdoor experience plus the bonus of red light support, all without the financial or space commitment of a large, premium build. It is a smart pick for anyone who wants to test-drive regular sauna use at home while still enjoying some modern wellness features. Check out our list of the best red light therapy masks for some other devices that use similar technology.

Rachel tested this sauna, giving her overall experience a 3 out of 5. She liked how the controls were easy to access and use, but she found the seating uncomfortable and thought there was little room to move around within it. 

The SAUNABOX Pulse Pro maintained its temperature very well while Rachel was using it. “This sauna had a box inside of it that heated up the whole sauna, and the controls were easy to use and adjust while inside. While getting in and out of the sauna, some cold air would enter, but it would quickly return to its original heated temperature,” she said. 

She found the seating aspect of this sauna less than ideal, rating it a 2 out of 5. The seating would be more comfortable for a short session, Rachel noted. “The seating was crunched and uncomfortable. You’re basically sitting in a lawn chair,” she said. She fit perfectly into the sauna, and is 5 feet 5 inches tall, but thinks that anyone who is taller than that may feel cramped while using it.

Our tester was pleased by the aesthetic aspects of this sauna, rating it a 4 out of 5 in this category. “This sauna looks very appealing and because of its small size, can fit perfectly outside of your home.” She also thinks that it would fit well inside of your home, due to its look and limited amount of space that it takes up.

Other Saunas We Tested and Considered

We tested multiple saunas with different features and benefits. Here’s one that didn’t make our list of picks, and why:

• Sunlighten Solo: Our tester encountered some trouble getting in and out of this solo sauna, and also noted that the temperature wasn’t quite hot enough

How We Tested and Selected the Best Outdoor Saunas

How we tested and selected the best outdoor saunas focused on how these units actually perform outside a lab: in real backyards, across weather conditions, and with different household sizes and routines in mind. The goal was to highlight models that not only deliver strong heat-therapy benefits but also justify their price through durability, ease of use and everyday comfort for solo soakers and families alike.

Performance

During testing, each sauna had to reliably reach and maintain its target temperature, and evaluators closely tracked how quickly the unit heated from a cold start to a typical session range. Testers also paid attention to the type of heater, because some offered faster heat-up times and more consistent temperatures, which can be crucial in colder climates.

Comfort

Comfort testing centered on whether people could actually relax for a full session, not just tolerate the heat. Testers evaluated bench depth and height, back support, foot space and overall interior layout, then checked whether a two-person or five-person sauna could realistically fit that many adults without feeling cramped or forcing awkward seating positions.

Controls 

Usability played a major role in scoring: models that offered simple, intuitive controls were rated highest. Testers looked for clearly labeled temperature and time settings, easy-to-grip timer knobs or digital panels, and convenient placement of controls so users could adjust their session.

Features

Beyond the basics, extra features helped certain outdoor saunas stand out. Our testers noted thoughtful touches like towel hooks, interior and exterior lighting, Bluetooth speakers, cup holders and integrated phone shelves, while also checking that add-ons did not complicate operation or detract from core heating performance.

Value

Value in an outdoor sauna comes down to how much performance, comfort and durability you get for the price—not just the lowest sticker cost. Factors like capacity, materials, heater type, warranty and operating costs all play into whether a sauna will be a smart long-term investment for you.

How to Find the Best Outdoor Sauna for You

Not everyone uses a sauna the same way: some folks want intense post‑workout heat, others prefer gentle, meditative sessions, and many are working with tight patios or big family backyards. The best outdoor sauna for you comes down to how you plan to use it, how much space you have, and which features feel essential versus nice‑to‑have. 

Available Space

Before falling in love with a particular sauna design, carefully measure the exact spot you plan to use, including clearance for doors, steps and safe distances from fences, plants and overhead structures. We also recommend that you account for delivery paths and assembly room, since many outdoor saunas arrive in large panels or kits that need maneuvering around corners and through gates.

Materials

Focus on saunas built from sturdy, weather‑resistant woods like cedar, hemlock or thermally modified spruce. Look for rust‑resistant hardware, quality roofing and insulated walls so your sauna holds heat efficiently and requires less maintenance over time.

Safety

A good outdoor sauna should have clear ventilation, properly rated electrical components, and a stable foundation to reduce tipping or shifting over the years. Check that heaters are certified, doors open easily from the inside, and any glass is tempered. Always plan to follow manufacturer guidelines for installation and use as well.

Tech and Features

Think about how much tech you’d like to be included: some people love app control, Bluetooth speakers and color‑changing lights, while others prefer a simple dial and a quiet cabin. Prioritize features that genuinely enhance your sessions over extras that add cost without improving your experience.

Sauna Type

Consider how quickly you want the sauna to heat up, if you enjoy dry or steamy sessions and how much peak temperature matters to you. Here are the types of saunas you can choose from:

• Traditional dry sauna: Uses an electric or wood‑burning heater with hot rocks for high, dry heat and the option to add light steam by pouring water over stones; great for classic sauna rituals and very hot sessions. 
• Infrared sauna: Uses infrared heaters to warm the body directly at lower air temperatures, often with faster warm‑up times and a gentler feel that some people find easier to tolerate. 
• Steam sauna: Relies on a steam generator to create high humidity and lower apparent temperatures, which can feel soothing for the skin and airways but needs more moisture management. 
• Hybrid or full‑spectrum units: Combine traditional elements with infrared or add multiple infrared wavelengths, giving you the flexibility to choose more intense or milder sessions.

Cost

Budget for the full picture: purchase price, installation (including electrical work and foundation) and ongoing energy use. Higher‑end models often cost more upfront but can offer better insulation, more efficient heaters and longer warranties, which may pay off over years of regular use.

Benefits of an outdoor sauna

An outdoor sauna can deliver many of the same wellness benefits as spa or gym saunas while adding the ritual of stepping outside and alternating heat with fresh air. For many people, having the sauna at home also makes it easier to use consistently, which is key for long‑term health effects. Here are some benefits of using an outdoor sauna:

• May help support circulation and cardiovascular health, as heat exposure can increase heart rate and blood vessel dilation in a way similar to light exercise. 
• Potential relief of muscle soreness and joint stiffness, especially when used after training or long days on your feet. 
• Relaxation and stress reduction, thanks to the combination of warmth, quiet, and time away from screens and chores. 
• A dedicated wellness space that can boost overall recovery routines when combined with sleep, hydration, and movement habits.

Frequently asked questions

Is it worth getting an outdoor sauna?

For folks who will use it several times a week, an outdoor sauna can be a meaningful investment in recovery and relaxation at home. If it fits your budget, space, and climate, the convenience and consistency can outweigh the cost of repeated spa visits.

What is the best type of sauna to buy?

The best type of sauna is the one you will get plenty of use out of: traditional saunas suit those who like very hot, dry sessions, while infrared or hybrid models tend to appeal to folks who want gentler heat and potentially lower operating temperatures.

What’s better, an infrared or steam sauna?

Neither is necessarily better; infrared offers lower‑temperature, dry heat that many find comfortable for longer sessions, while steam provides a humid environment that can feel more intense and may benefit people who enjoy moist heat.
