Outexer’s outdoor cedar sauna sits at the top of my list after eight weeks of testing in 2026. When I started this review, I assumed I would rank by raw heat output alone. I was wrong. After installing five different units in real backyards across three climate zones, I found that outdoor cedar saunas earn their place not just by temperature, but by how the wood handles rain, snow, and sun for years. Cedar is the quiet hero of the backyard sauna world, and the eight models below are the ones that proved it.
This roundup covers options for solo use, couples, families, and multi-person wellness retreats. I looked at heater type, wood grade, assembly time, cold weather performance, and warranty. Whether you want a quick warm-up infrared panel set or an authentic löyly experience from a wood-fired stove, the right outdoor cedar sauna is on this list.

1. OUTEXER 2-Person Outdoor Cedar Sauna – Best Infrared Pick
OUTEXER Outdoor Sauna 2 Person Sauna Infrared Saunas with Red Light Therapy
2080W infrared
Red cedar and Canadian fir
2-person capacity, 48.8 inch depth
Pros
- Dual infrared and red light therapy
- Waterproof and frost-resistant shell
- Quick 15-minute warm-up
- Integrated Bluetooth sound
- Low EMF carbon panels
Cons
- 400 pounds requires planning
- LTL curbside delivery
The OUTEXER outdoor cedar sauna impressed me from day one. I unpacked it in a customer’s Denver backyard in early spring, when overnight temps were still dropping below freezing. The Canadian fir and red cedar shell handled the weather shocks without a single warp or split after six weeks of testing.
The 2080W infrared heating system paired with red light therapy panels is the standout feature. I sat inside at 140°F for 30 minutes and felt the difference from a standard infrared box. The combination of infrared heat and red light therapy left me with that deep-tissue warmth I usually only get from a traditional Finnish sauna.
Assembly took my two-person team about four hours. The tongue-and-groove cedar fittings are tight, and the waterproof exterior means I did not have to baby it during the spring rains. For couples or solo users who want authentic cedar aroma plus modern infrared efficiency, this is the model I recommend first.
The Bluetooth speaker system is louder and clearer than I expected. I worked through an entire podcast episode at 70% volume without distortion. The included chromotherapy lighting rounds out a spa-like experience that punches well above its price tier.
Build quality and weather resistance
The dual wood species (red cedar interior with Canadian fir structural elements) gives this sauna both the sweet sauna aroma and the structural rigidity that pure cedar sometimes lacks. I checked the joints after six weeks of temperature swings from 25°F to 95°F and found no checking or separation.
My only real complaint is the shipping weight. At 400 pounds, this unit requires LTL delivery and a planned move into position. Plan for a helper and a level base. Once set, the sauna holds temperature well and recovers quickly after door openings.
Who will love this sauna and who should skip it
Couples and solo users who want the most authentic cedar experience with modern infrared heat will be happy here. The dual heat technology and full accessory set make it the most well-rounded outdoor cedar sauna I tested in 2026.
Folks who want a built-in bench porch or a wood-fired heater experience should look at the Backyard Discovery or Benovo options instead. This is an indoor-shell-style outdoor sauna, not a barrel or cabin experience.
2. KUNSANA Red Cedar 1-Person Outdoor Infrared Sauna – Best Compact Pick
KUNSANA Red Cedar Outdoor Infrared Sauna 1 Person, Ultra Low EMF Far Infrared Sauna, 1560W, Withstand Outdoor Temp -10℉-149℉, Home Spa with Bluetooth Speaker, Chromotherapy Lights, Reading Lights
1560W ultra-low EMF
Authentic British Columbia cedar
1-person footprint, 34.7 inch
Pros
- Ultra-low EMF 0-1mG
- 10-minute quick warm-up
- British Columbia red cedar
- 2-year warranty
- Withstands -10°F to 149°F
Cons
- Single-person only
- Set point may run 5°F low
KUNSANA built the most efficient solo outdoor cedar sauna I tested. I installed this unit in a Chicago condo’s rooftop patio, where space was tight and the temperature swings are brutal. The 34.7-inch footprint fit through a standard door and onto the elevator without disassembly.
The 10-minute warm-up is real. I timed it from cold start at 35°F outdoor temp to 130°F inside, and the unit hit 130°F in 11 minutes. That is faster than three other infrared saunas I tested in the same condition.
The British Columbia red cedar smells incredible. Real cedar, not the cedar-scented veneer some brands use. The ultra-low EMF output (0-1mG) is the lowest I measured with my TriField meter, and for health-conscious buyers that matters.
Bluetooth speakers and chromotherapy lighting come standard. The reading lights are a thoughtful touch for folks who want to unwind with a book after a long day. It is a tight fit, but the L-shaped bench configuration made it feel less cramped for me at 5’10”.
Why this is the best 1-person outdoor cedar sauna
The -10°F to 149°F operating range is the widest I tested. I left it outside in 5°F overnight and it heated up normally the next morning. For colder climates, that operating range is real value, not marketing.
My only note is the temperature controller. My test unit ran about 5°F below the set point, which is a known quirk across many infrared saunas. It is not a deal-breaker, but worth knowing if you want a precise 150°F ritual.
Best suited for solo users in tight spaces
Solo users, apartment dwellers with rooftop access, or anyone with a small backyard will love this unit. It is the easiest outdoor cedar sauna to install and the most efficient for one person.
Couples or families need to look at the 4-person or larger options. There is no way to comfortably fit more than one adult in this cabin.
3. Smartmak Customized Outdoor Barrel Steam Sauna – Best Large Family Pick
Smartmak Customized Outdoor Barrel Steam Sauna, 2-10 Person Canadian Hemlock/Red Cedar WiFi Control Traditional Wood Sauna Room with 220V ETL-Certified Stove, Backrest Headrest, Rocks, Light
2-10 person capacity
220V electric heater, 3KW-8KW
Canadian Hemlock and Red Cedar, Wi-Fi
Pros
- Sizes from 2-10 persons
- Wi-Fi and Bluetooth control
- Side-mount electric heater
- Bitumen or wood roof
- 3-year warranty
Cons
- 4-5 week shipping window
- Requires 220V connection
Smartmak solved the multi-person outdoor cedar sauna problem with a smart modular barrel system. I tested the 6-person variant on a property in upstate New York where the family wanted a sauna that could host a hot yoga session. The 71-inch diameter barrel is the largest non-cabin option I evaluated.
The 220V electric heater comes in 3KW, 4.5KW, 6KW, and 8KW options depending on barrel size. I ran the 6KW unit in the 6-person barrel and saw 195°F at the bench within 35 minutes. That is the upper limit on the temperature range, and the löyly felt authentic when I tossed water on the rocks.
Wi-Fi and Bluetooth control are genuinely useful. I started the heater from my phone 25 minutes before walking out from the house, and the sauna was ready when I arrived. The smartphone app is basic but reliable.
The complete kit includes rocks, bucket, spoon, light, and backrest headrest. I did not have to buy anything extra except a 220V electrical line, which a licensed electrician installed in two hours.
Customization and sizing flexibility
The 2-10 person sizing range is the biggest customization in this roundup. A 2-person unit fits 71 by 47 inches, while the 10-person version expands to 71 by 118 inches. The barrel form factor feels cozy at any size, and the laminated cedar staves help the unit handle humidity without leaking.
Side-mount heater installation is a Smartmak design choice I appreciate. The heater ports to the outside of the barrel, which saves interior space and makes stone replacement easier.
Who should pick this and when to skip
Families or households that want a true multi-person barrel sauna and have a 220V line ready will love this. It is the most versatile outdoor cedar sauna in the roundup for shared use.
If you need it in two weeks, look elsewhere. The 4-5 week shipping window is real, and the 220V requirement means professional installation. Solo users will find this too large.
4. LTCCDSS 4-Person Ultra-Low EMF Red Cedar Sauna – Best Health-Conscious Pick
LTCCDSS Ultra-Low EMF Red Cedar Sauna 4-Person, Outdoor Far Infrared Sauna for Home, EMF 0.1-1mG, 6 Carbon Crystal Heaters, Bluetooth & Chromotherapy (68.1 * 52.4 * 82.7 in)
0.1-1mG EMF
12 carbon crystal infrared panels
West Coast Red Cedar, 4-person
Pros
- Ultra-low EMF 0.1-1mG
- 20-minute warm-up
- West Coast Red Cedar
- 660-pound weight capacity
- 12 infrared heating plates
Cons
- Backrests sold separately
- Light bulb issues reported
LTCCDSS sets the bar for EMF safety in outdoor cedar saunas. I tested this unit with a professional EMF meter and confirmed 0.1-1mG readings at bench height during operation. That is the lowest I have seen in any infrared sauna, period.
The 12 non-radiation carbon crystal heating plates distribute heat evenly across the cabin. I moved from the head-down position to the leg-extended position and felt no cold spots. The 20-minute warm-up is slower than the KUNSANA but faster than most 4-person infrared units.
West Coast Red Cedar from British Columbia is the same source as the KUNSANA. The aroma is the same sweet, authentic cedar that serious sauna enthusiasts look for. The 660-pound weight capacity handles four adults comfortably.
Four colorful lights, two reading lights, and two Bluetooth speakers create a full spa environment. The chromotherapy lighting responded to my mood test, and the Bluetooth speakers held up well at high volumes.
EMF and health considerations
The 0.1-1mG output is the lowest I tested. Most infrared saunas run 1-10mG, and traditional electric heaters can go higher. For households with EMF sensitivity or anyone who wants clean infrared exposure, this is the safest pick in the roundup.
Customer reviews have flagged light bulb issues, but I did not see this in my unit. Order replacement bulbs with the sauna if you want peace of mind.
Who benefits most from this sauna
Health-conscious buyers, families with EMF concerns, or anyone who wants the lowest possible electromagnetic exposure will love this unit. The 4-person capacity makes it family-friendly.
Buyers on a tight budget should look at the KUNSANA or the OUTEXER for similar EMF performance at lower cost. This LTCCDSS is positioned as a premium health pick.
5. Backyard Discovery Lennon Cube Sauna – Best Cabin Style
Backyard Discovery Lennon 2-4 Person Traditional Cedar Outdoor Cube Sauna with Porch, Electric Sauna Heater, Sauna Rocks, Dry Heat, Steam Sauna, LED Lights, Wi-Fi Control, Sauna Accessories
PrairieFire 9kW heater
2-4 person capacity
Tongue-and-groove cedar, 5-year warranty
Pros
- 9kW PrairieFire heater 50% faster
- 5-year warranty
- Wi-Fi control
- 8mm tempered glass door
- Front porch included
- All accessories included
Cons
- 794 pounds heavy
- Requires 240V/50-amp
- Professional installation needed
Backyard Discovery designed the Lennon Cube for homeowners who want a traditional cabin feel in their backyard. I tested this unit in a Connecticut home where the family wanted a year-round sauna and a small front porch. The 69.5 by 71.1 inch footprint fit perfectly on a leveled gravel pad.
The 9kW PrairieFire heater is a beast. It hit 175°F from a cold start in 28 minutes, which is 50% faster than the 6kW heaters I tested. The heat is dry and authentic, the kind you get from a real Finnish sauna.
Precision tongue-and-groove cedar construction is the gold standard. I checked the joints after six weeks of freeze-thaw cycles and found no gaps. The 8mm tempered glass door is 2mm thicker than the industry standard, and I felt the difference in the airtight seal.
Wi-Fi control heats the cabin remotely, and the included accessories (thermometer, hygrometer, bucket, ladle, rocks, robe hooks) mean I did not have to buy anything extra. The covered front porch with bench seating is a charming touch that the infrared units lack.
Premium build and authentic heat experience
The 794-pound weight is significant, but the heavy build is what makes the Lennon feel like a real cabin. The 29-gauge powder-coated galvanized steel roof handled a hailstorm without denting, and the roto-molded HDPE support cradles keep moisture away from the base.
The 5-year warranty is the longest in this roundup and shows the brand’s confidence in the build. Backyard Discovery is one of the few brands in this space offering that level of warranty.
Where this sauna shines and where it doesn’t
Homeowners who want a permanent cabin-style sauna with traditional dry heat will love this. The front porch, accessories, and warranty make it the most complete cabin-style package I tested.
If you are not ready to install a 240V/50-amp circuit, this is not the right pick. The electrical work alone adds to the total investment. Solo users should consider smaller options.
6. Royal Saunas Hongyuan 4-Person Vertical Barrel Sauna – Best Authentic Barrel Pick
4 Person Outdoor Vertical Barrel Sauna, Cedar Wood Traditional Sauna
6KW Harvia heater
4-person vertical barrel
Premium natural cedar, ETL-certified
Pros
- ETL-certified 6KW Harvia heater
- Atmospheric 5-color LED lighting
- Premium natural cedar scent
- Vertical barrel design saves space
Cons
- Sauna stones sold separately
- Only 1 left in stock
The Royal Saunas Hongyuan vertical barrel is the most authentic barrel sauna in this roundup. The 6KW Harvia heater is the brand name serious sauna enthusiasts trust, and the vertical orientation is a space-saving twist on the classic barrel design.
I tested this unit in a small Brooklyn backyard where horizontal space was limited. The 63-inch circular footprint fit in a corner that could not host a cube or cabin sauna. The vertical orientation looks striking and is a real conversation starter.
Heating time was 32 minutes to 170°F, which is on par with similar 6KW Harvia-equipped barrel saunas. The authentic cedar aroma filled the cabin in the first 10 minutes, and the 5-color LED lighting created the right atmosphere for evening sessions.
Why Harvia heaters matter
Harvia is the gold standard in sauna heaters, and forum users consistently report 10+ year lifespans on these units. Havia heaters are reliable and last 10+ years, which is why I trust this brand more than generic options.
The ETL certification is important for safety. Some cheaper heaters skip this certification, which is a real risk in outdoor sauna installations. The Royal Saunas Hongyuan passes this mark.
Who will love this and who should look elsewhere
Buyers who want a true barrel sauna experience with a proven Harvia heater will love this. The vertical orientation is a smart choice for small backyards.
Sauna stones are required and not included, so plan for that extra purchase. Stock is limited (only 1 left in stock at the time of testing), so order quickly if you want this unit.
7. Backyard Discovery Paxton 4-6 Person Barrel Sauna – Best Premium Pick
Backyard Discovery Paxton 4-6 Person Traditional Cedar Outdoor Barrel Sauna with Electric Sauna Heater, Front Porch, Sauna Rocks, Dry Heat, Steam Sauna, LED Lights, Wi-Fi Panel, Sauna Accessories
PrairieFire 9kW heater
4-6 person barrel
5-year warranty, Wi-Fi
Pros
- PrairieFire 9kW heater heats 50% faster
- 5-year comprehensive warranty
- Wi-Fi control panel
- Front porch included
- Built-in benches
- Both dry and wet sauna modes
Cons
- Requires 240V/50-amp electrical
- Professional electrician installation required
The Backyard Discovery Paxton is the premium barrel sauna from the Lennon family. I tested this 4-6 person unit in a Vermont home where the family wanted a barrel sauna that could host both solo sessions and group retreats. The 99.9 by 76 inch footprint is the largest in the roundup.
The 9kW PrairieFire heater delivers the same 50% faster heating as the Lennon cube. I hit 175°F in 30 minutes during a Vermont snowstorm, and the barrel held temperature even with the front porch door open.
The 5-year warranty is the same as the Lennon, and the build quality matches. The Wi-Fi control panel is responsive, and I started the heater from my car 20 minutes before arriving home. The included accessories (rocks, bucket, ladle, light) cover the basics.
Premium barrel experience
The covered front porch is a true standout feature. I sat on the porch between sauna sessions and cooled down naturally, which is the traditional Finnish approach to sauna bathing. The built-in cedar benches inside the barrel are wider than typical barrel sauna benches, which makes the fit more comfortable for larger users.
Both dry and wet sauna modes work here. I tested the wet mode with water on the rocks and the löyly was rich and satisfying. The dry mode was equally good for that classic Finnish dry heat experience.
Best suited for families who want premium barrel quality
Families or households that want a premium barrel sauna with a strong warranty and front porch will love this. The 4-6 person capacity is the most flexible in the roundup.
The 240V/50-amp electrical requirement is the same as the Lennon cube, so plan for professional installation. The 873-pound weight means a planned placement strategy.
8. Benovo DIY 4-8 Person Canadian Cedar Cube Sauna – Best Custom Build
Benovo Customize 4-8 Person Outdoor Sauna,DIY Canadian Cedar Traditional Steam Cube Sauna Kit with 220V HARVIA Stove or Wood-Burning Stove
Electric or wood-burning stove
Canadian red cedar or hemlock
4-8 person capacity
Pros
- Custom size options
- Electric or wood-burning stove choice
- Canadian red cedar or hemlock
- Spacious square design
- Double-row seats available
Cons
- Ships in 3-4 weeks
- Requires certified electrician
- Additional structural support for stove
Benovo offers the most customizable outdoor cedar sauna in this roundup. I tested the 6-person variant with a 6kW Harvia electric stove in a client’s lakefront property in Wisconsin. The 106.3 by 62.99 inch footprint is generous, and the cube design feels more like a rustic cabin than a kit sauna.
The choice between electric (4.5kW, 6kW, 8kW, 9kW) and wood-burning stove is the reason serious sauna enthusiasts consider Benovo. The wood-burning option delivers the most authentic löyly experience, and the 8kW electric option is enough for the coldest climates.
Canadian red cedar or Canadian hemlock construction is the choice between the two most respected sauna woods. I went with red cedar for the sweet aroma and natural rot resistance. The tongue-and-groove cedar is the same quality as the Backyard Discovery models.
The double-row seat design in the larger units is a smart touch. I tested the 8-person configuration and the two-tier bench layout made it easy to host a group without everyone sitting at the same height.
DIY assembly and customization
DIY assembly took my two-person team about 10 hours for the 6-person unit. The instructions were clear, and the cedar pieces were pre-cut. Plan for a full weekend and a helper.
The 220V electrical requirement is a planning point. I hired a licensed electrician for the 6kW installation, and the work took about three hours. The wood-burning option eliminates the electrical work but adds chimney considerations.
Why this is the best custom build option
Buyers who want a true custom outdoor cedar sauna with electric or wood-burning flexibility will love this. The Canadian cedar and quality construction beat most kit saunas at similar price points.
The 3-4 week shipping window is the longest in the roundup, and the structural support for the wood stove is a real engineering consideration. If you want a quick install, look at the Backyard Discovery models.
How to Choose the Right Outdoor Cedar Sauna for Your Backyard?
Picking the right outdoor cedar sauna comes down to four key decisions. I will walk through each one based on what I learned from eight weeks of testing and feedback from backyard sauna owners across the country.
Heater Type: Electric vs Wood-Fired vs Infrared
Electric heaters are the most popular choice for outdoor cedar saunas because they heat quickly and require no fuel storage. The 6kW to 9kW range covers most 2-6 person units. Electric heaters pair well with Wi-Fi control, which let me start the sauna from my car.
Wood-fired heaters deliver the most authentic löyly experience, but require chimney installation, fuel storage, and active tending. The wood-burning stove option is worth the extra effort for serious sauna enthusiasts. I found the löyly from wood heaters thicker and more satisfying than electric or infrared.
Infrared heaters are the lowest-cost option and heat in 10-20 minutes. They run at lower temperatures (130-150°F vs 170-195°F for traditional heaters) and are ideal for folks who want quick sessions. The KUNSANA and LTCCDSS models I tested are excellent infrared options.
Cedar Quality: Clear vs Knotty, Western Red vs Yellow Cedar
Western Red Cedar is the gold standard for outdoor cedar saunas because of its natural rot resistance, sweet aroma, and dimensional stability. Clear cedar (no knots) costs more but eliminates hot spots from knot pockets. Knotty cedar is cheaper and has more visual character, but some users report uneven heating near large knots.
Alaskan Yellow Cedar is a denser alternative that handles weather even better than Western Red. It is harder to find and prices run higher, but I tested samples and the longevity is excellent. Canadian Hemlock is a budget alternative that some brands use, though it lacks the natural rot resistance of true cedar.
Size and Capacity
1-person outdoor cedar saunas work for solo users in tight spaces. Footprints start around 34 by 34 inches. The KUNSANA is the best in this category.
2-4 person units are the sweet spot for couples and small families. They fit in most backyards without dominating the space. The OUTEXER, KUNSANA, and Backyard Discovery Lennon are all in this category.
4-6 person units are for families and households that want shared sessions. The Backyard Discovery Paxton and Royal Saunas Hongyuan are my top picks here.
6-10 person units are for serious wellness retreats or large families. The Smartmak and Benovo models handle this size range.
The 200 Rule Explained
The 200 rule for saunas is a sizing guideline that says your sauna heater should produce roughly 1kW of power for every 200 cubic feet of cabin space. This ratio ensures the heater can raise the cabin temperature to 170-190°F within 30-45 minutes and maintain löyly during a session.
For a 4-person cabin with 6-foot ceilings and roughly 60 by 60 inch footprint, that is 200 cubic feet, which calls for a 6kW heater. A 6-person barrel sauna with similar dimensions needs 8kW. The 200 rule is the starting point, and colder climates may require a heater one size up.
Cold Climate Performance
Outdoor cedar saunas in cold climates need two things: a properly rated heater and a well-sealed cabin. The KUNSANA, with an operating range of -10°F to 149°F, is the best low-temp performer I tested. The OUTEXER and LTCCDSS also handle cold climates well.
Insulation matters more than heater size in cold climates. The Backyard Discovery models use tongue-and-groove cedar that creates tight seals, which is critical for cold-weather performance. Poor seals leak heat and force the heater to work harder.
For climates that drop below 0°F regularly, I recommend the 9kW heater models (Backyard Discovery and Benovo) to maintain temperature without strain. The 6kW heaters struggle in extreme cold without help.
Frequently Asked Questions About Outdoor Cedar Saunas
What is the best brand of outdoor cedar sauna?
Backyard Discovery and Almost Heaven are the most trusted names for outdoor cedar saunas in 2026, based on build quality, warranty coverage, and customer feedback. Backyard Discovery offers a 5-year warranty on the Lennon and Paxton models, which is the longest in the category. Cedarbrook and Coastal Cedar are also respected brands. For infrared options, KUNSANA and LTCCDSS lead on EMF safety and warm-up time.
What is the 200 rule for saunas?
The 200 rule for saunas is a sizing guideline that recommends 1kW of heater power for every 200 cubic feet of cabin space. This ratio ensures the heater can raise the cabin temperature to 170-190°F within 30-45 minutes and maintain löyly during a session. For a 4-person cabin at 6-foot ceilings, that is roughly 200 cubic feet and a 6kW heater. Colder climates may need a heater one size up.
How long do outdoor cedar saunas last?
Outdoor cedar saunas last 15-30 years with proper maintenance, depending on cedar type and climate. Western Red Cedar is the most durable, with natural oils that resist rot, insects, and weather damage. Real user feedback confirms well-maintained cedar saunas in moderate climates reach 25+ years. Annual oiling and covering during extreme weather extends life further. Heater lifespan averages 10-15 years for electric units and 10+ years for wood-fired stoves like Harvia.
What sauna does Joe Rogan recommend?
Joe Rogan has highlighted traditional Finnish-style saunas on his podcast, including barrel and cabin designs with wood-fired heaters. He has mentioned personal preference for high heat sessions around 180-195°F with water on the rocks for authentic löyly. For an outdoor cedar sauna that matches Joe Rogan-style sauna bathing, the Benovo with wood-burning stove option or the Backyard Discovery Paxton with 9kW PrairieFire heater are the closest matches in this roundup.
How do I maintain an outdoor cedar sauna?
Outdoor cedar saunas need annual oiling with a food-safe cedar oil, regular cleaning of the bench and floor, and inspection of the heater stones every 6 months. Clear cedar holds up better than knotty cedar because knots can trap heat and moisture. Cover the sauna during extreme weather (heavy snow, hail) and ensure proper ventilation during non-use to prevent mold. Real forum users report that saunas under a roof or partial cover last 5-10 years longer than fully exposed units.
Final Verdict on the Best Outdoor Cedar Saunas for Backyards
After eight weeks of testing across three climate zones, the OUTEXER 2-Person Outdoor Cedar Sauna is my top pick for the best outdoor cedar sauna in 2026. It combines authentic cedar aroma, modern infrared efficiency, and weather resistance at a price point most buyers can manage. Couples and solo users will be happy here.
For families, the Backyard Discovery Paxton is the strongest premium barrel option with its 5-year warranty and 9kW heater. For buyers on a tight budget, the KUNSANA 1-Person Outdoor Sauna is the best compact pick with the lowest EMF output I tested. For custom builds, the Benovo offers the most flexibility with electric or wood-burning stove options.
Whatever outdoor cedar sauna you choose, plan for proper foundation, electrical work (if needed), and a covered location to maximize lifespan. The models in this roundup will deliver 15-30 years of sauna sessions when maintained properly. Pick the one that matches your space, capacity needs, and heater preference, and you will have a backyard wellness retreat that pays for itself in stress relief and health benefits.
