Best Sauna Tent 2026 — Everything You Need to Know Before Buying

A sauna tent is a real sauna you can pack in a bag. Wood-burning stove, chimney, three-layer construction — it reaches 80-100°C in 15-30 minutes. And you can take it with you.

The garden. The cabin. The campsite. The patio. It doesn't matter. Set it up in 5 minutes, light the fire, and wait. No building permit. No electrician. No foundation.

Friluftsfreak.dk rated Smelt Elda as the best sauna tent in their test. We're proud of that. But this guide isn't just about selling you something — it's about giving you everything you need to know so you can make the right choice.

Let's get started.

What is a sauna tent — and what is it not?

A sauna tent is a tent built specifically for sauna use. It's not a camping tent with a stove in it. The difference is crucial.

A proper sauna tent has three-layer construction: an outer fabric that keeps wind and weather out, an insulating middle layer that keeps heat in, and an inner fabric that protects the insulation. Without those three layers, you can't reach sauna temperatures. You just get a warm tent.

And then there's the stove. A stainless steel sauna stove with chimney, ash drawer, and stone compartment for sauna stones. That's what does the work. Wood in, fire on, heat out.

What it is NOT

It's not an infrared sauna. It's not a steam bath. It's a traditional, Finnish-inspired sauna with real heat from wood. The smell of birch, the crackling of the fire, the heat that hits you when you open the door — that's the real deal.

And let's be honest: it takes a bit of effort. You need firewood. You need to light it. You need to wait 15-30 minutes. It's not a button you press. But that's part of it, too. Slowing down. Being intentional. Taking your time.

Smelt Elda — best in test for families and groups

Elda is our large model. 4-10 people. Friluftsfreak.dk rated it number 1 in their sauna tent test — and we certainly agree.

But let's look at why.

Size and space

Elda has full standing height. You can stand up inside without ducking your head. It sounds trivial, but try sitting in a sauna where you can't straighten your back — it gets uncomfortable fast.

4-10 people is the official capacity. In practice, 6 adults sit comfortably with plenty of room to move around. 8-10 is possible, but it gets tight. Think about how many you typically are, and choose accordingly.

Materials and construction

Three-layer construction in Oxford 300D polyester. Outer layer, insulating cotton middle layer, inner layer. That's what gives it its insulating ability — and that's what allows Elda to reach high temperatures, even in windy conditions.

TPU windows with 8 window shutters. You decide how much light comes in and whether you want to look out while sitting inside. 2 ventilation openings — one at the top and one at the bottom of the chimney wall — give you full control over air circulation.

The door is full height. Not a half-door you have to crawl through. You walk in and out as in a normal room. And it closes with two door pins attached with velcro — simple and durable.

Heating

15-30 minutes. It depends on the weather. A calm summer evening? 15 minutes. A windy winter day? Closer to 30. But you'll reach 80-100°C regardless — the three-layer construction ensures that.

Tip: Close all window shutters and ventilation openings for the first 15 minutes for the fastest warm-up. Open them once you've reached your desired temperature.

What's the limitation?

It's big. And it weighs something. You'll notice if you have to carry it far. For the garden, the car, or a cabin, it's fine. For a hiking trip? No.

But the size is the point. You buy Elda because you want space. Space to sit comfortably with friends and family, without feeling like you're sitting on top of each other.

Smelt Glöd — best for couples and small groups

Glöd is the compact model. 2-6 people. And it uses exactly the same materials and the same stove as Elda.

When does Glöd make more sense?

If you're typically 2-4 people. If you have a smaller garden or patio. If you want to bring the sauna to the cabin without filling the entire boot. Or simply if you prefer a smaller space — some people actually find the closer, more intimate atmosphere in Glöd better.

Faster heating

Because the volume is smaller, Glöd reaches 80°C in 15-20 minutes. That's a real advantage in everyday life. A Tuesday evening at 8 PM where you just want 15 minutes in the heat — every minute of warm-up time counts.

Same quality, just smaller

Oxford 300D polyester three-layer. Same stove. Same chimney pipes. Same stone compartment. Same window shutters and ventilation. We haven't cut corners on Glöd — it's simply compact.

There's full standing height — same as in Elda.

What's the limitation?

Space. If there are more than 4 of you, it gets tight. And if you like to stretch out and have elbow room, and you're typically a larger group — then Elda is the right choice.

Glöd vs. Elda — which one should you choose?

That's the question we get most often. And the answer is quite simple.

Rule of thumb: Think about how many you typically are, and add 2. "It's just the two of us" → Glöd is perfect. "We're a family of four, and we'll probably invite someone along" → go with Elda. You never regret extra space. You always regret too little.

Setup — step by step

It takes about 5 minutes. One person can do it. No tools needed.

Step 1: Unfold the tent

Take the tent out of the carry bag and unfold it on a flat surface. Make sure there's at least 2 metres of distance to buildings and combustible materials.

Step 2: Raise the tent

Pull the cord in the middle of each wall and push the roof up from the inside. It sounds simple, and it is. The tent raises itself when you lift the centre.

Step 3: Stake it down

Use the 6 included stakes. In windy conditions, you should also use the 4 guy ropes for extra stability.

Step 4: Attach the door pins

The two door pins are fastened with velcro. It takes 30 seconds.

Step 5: Place the stove

Assemble the 6 chimney pipes, put them together, and place the stove in the tent. The chimney goes up through the hole in the top. The fire mat goes under the stove — it's included.

Step 6: Light the fire

Fill the stove with dry firewood (birch is recommended), use a fire starter to light it, and wait. Close all window shutters for the fastest warm-up.

The first time it might take 10 minutes. By the third time you'll do it in 5.

Firewood — what to use and what to avoid

This section is more important than it sounds. Wrong firewood can be dangerous, and the right firewood makes a huge difference for your sauna.

Always use dry, hardwood

Birch is the best. It burns cleanly, gives even heat, and a light, pleasant scent. Oak and beech also work well — they burn a bit longer but produce less scent.

A sauna session typically uses 3-5 kg of firewood. That's about 5-10 DKK per session. Compare that to a gym membership at 300-500 DKK per month or a ticket to a public sauna at 75-100 DKK per visit. Most people have earned back their sauna tent in under a year just from the saved expenses.

What you must NEVER use

• Softwood (spruce, pine) — it sparks and can spray embers into the tent
• Waste wood or painted wood — releases toxic fumes
• Lighter fluid directly on the fire — explosion risk
• Wet firewood — smokes heavily and gives poor heat

Fire starters are fine for getting the fire going. Never use petrol, alcohol, or other flammable liquids.

Storing firewood

Keep your firewood dry. Store it under a roof or in a firewood shed. Wet firewood is the most common cause of poor sauna heat and too much smoke. If the wood is wet, wait until it's dry. It's not worth trying.

Seasoning the stove — do it BEFORE first use

New stove? It MUST be seasoned first. This is not optional.

Seasoning means burning the stove outdoors for about 3 hours — without the tent, without stones. Just the stove, the chimney, and a good fire inside.

Why? Production oils and coatings need to be burned off. If you skip this and light the fire inside the tent the first time, you'll get unpleasant smoke and odour. Do it once, and it's done.

Fill the stove halfway with firewood, light it, and let it burn for 3 hours. Add more firewood each time it burns down. Let the stove cool completely afterwards. Done.

Maintenance — how to make your sauna tent last 5-10 years

A good sauna tent lasts 5-10 years. But it requires that you treat it properly. Fortunately, it's simple.

After each use

1. Leave the tent open for 15-20 minutes so the moisture evaporates. Open the door and ventilation openings.
2. Let the stove cool completely before touching it. Never pour large amounts of water on a hot stove — it can deform the steel.
3. Empty the ash drawer when the stove is cold. It takes 30 seconds and significantly extends the stove's lifespan.

Storage

Never roll up the tent while it's damp. That's the fastest way to mould, rusty zippers, and degraded seams. Let it dry completely, fold it up, and store it dry.

If the tent will be standing outside for an extended period, use a rain cover. It protects against UV rays and precipitation. Rain covers are included in the Premium and Deluxe packages.

Start of season

Check stakes, guy ropes, and zippers before the season. Look for wear on seams and fabric. And give the stove a quick check — is there rust? Are the chimney pipes still sealed? It takes 5 minutes and saves you from surprises.

Health benefits — what does the research say?

We're not doctors. But the research is quite clear, and it points in the same direction.

Heart and circulation

People who use a sauna 2-3 times per week have a 27% lower risk of cardiovascular disease. This is shown by a Finnish cohort study of 2,315 men followed over 20 years, published in JAMA Internal Medicine (Laukkanen et al., 2015). The heat dilates blood vessels and trains the circulatory system. It's essentially passive cardiovascular exercise.

The study showed that 4-7 sauna sessions per week had the greatest effect — 40% lower risk of death from all causes. But even 2-3 times per week made a clear difference. That's far more realistic when the sauna is in your own garden than if you have to drive to a gym or public sauna.

Sleep

This surprises many people. The sauna heat raises your core temperature. When you cool down afterwards, your core temperature drops extra low — and that's exactly the signal your body uses to initiate deep sleep. A meta-analysis of 13 studies (Haghayegh et al., Sleep Medicine Reviews, 2019) shows that passive body heating 1-2 hours before bedtime improves sleep quality and shortens the time it takes to fall asleep.

Many of our customers say that sleep is the biggest difference they notice. Not after a week — after the first session. 15 minutes in the sauna in the evening, and you sleep like a rock.

Recovery after exercise

Increased blood flow to the muscles helps reduce soreness after exercise. A study with basketball players (Ahokas et al., 2023) showed that sauna after exercise reduced muscle soreness and improved jump height compared to passive recovery.

The combination of heat followed by cooling (cold shower or just fresh air) is particularly effective. Blood vessels dilate in the heat and contract in the cold — this pumps fresh blood into the muscles.

Mental health

15 minutes without your phone, in warmth and silence. No notifications. No emails. Just you, the heat, and maybe a good conversation with whoever is sitting in there with you.

That's actually probably the most important benefit. Not something science needs to prove — you feel it yourself. The calm you have after a sauna is hard to find elsewhere.

Skin

The heat increases blood flow to the skin. Many of our customers report clearer skin with regular sauna use — but we haven't found strong clinical studies documenting this specifically for sauna. Take it as a bonus, not a promise.

Who should be cautious?

Consult your doctor before using a sauna if you have:

• Pregnancy
• Heart problems
• Diabetes
• Low blood pressure

Always have someone with you. Drink plenty of water before and after. Start with short sessions (5-10 minutes) and build up. Listen to your body — if you feel dizzy, step out.

Sauna tent vs. permanent sauna — what makes more sense?

A permanent sauna in the garden typically costs 30,000-100,000 DKK. It often requires a building permit, always a foundation, and usually an electrician or plumber for installation.

A sauna tent gives you the same sauna experience. Same temperatures. Same heat. Same sweat. The difference is:

• No building permit — a sauna tent is a temporary structure
• No installation — you set it up yourself in 5 minutes
• Portable — take it to the cabin, camping, events
• A fraction of the price — and you can get started today

Is a permanent sauna better? For permanent installation in the garden with electricity and water? Maybe ��� it depends on your priorities. But it costs 5-10x more, takes weeks to build, and you can't move it.

Most people who buy a sauna tent have considered a permanent sauna — and chose the sauna tent because they want the flexibility. You can take it to the cabin, set it up in a different spot in the garden, or pack it away for the winter. And you can get started right away instead of waiting for contractors.

What does it cost to own a sauna tent?

Let's do the maths.

Running costs

• Firewood: 3-5 kg per session × approx. 2 DKK/kg = 5-10 DKK per session
• Sauna stones: Replaced approximately once a year. Costs a couple of hundred DKK
• Maintenance: Close to zero if you dry the tent after use

Comparison

So yes — the investment pays for itself quickly. And you'll have the sauna tent for the rest of your life.

Accessories — what do you need?

The sauna tent and stove are the most important. But there are accessories that make it better.

Essential accessories

• Sauna stones (approx. 20 kg) — a must have. The stones store heat and keep the temperature higher and more stable. Plus you can pour water on them to create steam
• Bench — you can sit on the floor, but a bench lifts you into the hottest zone. We have two heights that fit both tents
• Heat-resistant gloves — the stove is hot. Really hot. Wear gloves when touching the stove or chimney

Nice to have

• Bucket and ladle — for pouring water on the stones and creating steam. Makes the whole sauna experience better
• Thermometer/hygrometer — analogue, no batteries, up to 120°C. So you know exactly what you're sitting in
• Sauna hat — protects your head from the most intense heat and helps your hair retain moisture. We have two types in wool — a classic sauna hat in three colours and a bucket hat in grey
• Rain cover — if the tent will be standing outside for an extended period. Protects against UV and precipitation

What you DON'T need

You don't need everything right away. Start with the tent, stove, stones, and firewood. You'll figure out the rest after your first few sessions.

Safety — the most important section in the entire guide

We take this seriously. A wood-burning stove is not a toy.

The 7 rules you must ALWAYS follow

1. Outdoors only — never in a garage, conservatory, tent halls, or other enclosed spaces. Carbon monoxide poisoning is life-threatening, and you can't smell it
2. 2 metres distance to buildings, fences, hedges, and anything combustible
3. Keep both ventilation openings open — they provide fresh air in the tent and oxygen for the stove
4. Have water nearby — a bucket of water, garden hose, or fire extinguisher
5. Children and pets away from the stove — minimum age of 16 for sauna use
6. Always have someone with you — don't use the sauna completely alone
7. Cool the stove gradually — never pour large amounts of water on a hot stove

Never use saltwater

Seawater or saltwater on the stove causes rust. Always use fresh water. It sounds obvious, but it happens — especially at the beach.

Clear chimney passage

Clean the chimney regularly. It's easier to keep it clean when you do it consistently, and you avoid soot build-up and stray embers.

Regulations for sauna tents in Denmark

A sauna tent requires no building permit. It's a temporary structure without a foundation — in the same category as caravans and garden furniture.

Where can you use it?

• Your own garden/property — freely, no permit required
• Private property — with the owner's permission
• Allotment garden — check the association's rules, they vary
• Campsite — most campsites allow it, but ask first
• Public areas — no. Sauna bathing with open fire and hot steam is not considered ordinary camping. Forests, beaches, national parks, and protected areas are not permitted per the Nature Protection Act §26 and §28

Always keep a minimum of 2 metres distance to buildings and combustible materials. This also applies to fences, hedges, and stored firewood.

Year-round sauna use — summer vs. winter

Summer

Faster warm-up. Milder contrast. Perfect for warm summer evenings where you combine sauna with a cold garden hose, a dip in the sea, or an ice bath. Many people use the sauna more in summer, simply because it's easier to go outside shirtless.

Winter

Longer warm-up, but this is when the sauna is at its absolute best. The contrast between 90°C inside the tent and -5°C outside is incredible. Snow on your feet after a round in the sauna. Hard to beat.

The three-layer construction means Elda and Glöd maintain the temperature, even in frost. It takes 5-10 extra minutes to warm up in winter — that's all.

Tip: Add a bit of extra firewood in winter. The stove has to work a little harder to keep the temperature up, but it handles it just fine.

Spring and autumn

The best time for sauna according to many. Fresh air, not too cold, not too warm. And the long bright evenings in April-May are perfect — light the sauna, do a few rounds, and finish with a cup of tea in the garden.

Your first sauna session — a guide

Never tried a sauna before? Here's what you can expect.

1. Drink water and eat lightly beforehand — don't go into the sauna on an empty stomach or right after a big meal. A glass of water and a light snack half an hour before is perfect.
2. Light the fire 20-30 minutes before you plan to go in. Let the temperature reach at least 70°C.
3. Take a warm shower first — it opens the pores and prepares your body.
4. Start low — sit on the floor or a low bench the first few times. Heat rises, so it's warmest near the ceiling.
5. 5-10 minutes per round is plenty in the beginning. Listen to your body.
6. Step out, cool down, drink water. Fresh air, cold shower, or just sit outside.
7. Repeat 2-3 times. Each round feels a bit different. The last round is typically the best.
8. Finish with cooling down and water. Drink at least half a litre of water afterwards.

It's normal to sweat heavily. It's normal for your heart rate to increase. It's normal to feel deeply relaxed afterwards. It's not normal to feel dizzy — if that happens, step out immediately.

Frequently asked questions

What does it cost to use a sauna tent?
3-5 kg of birch firewood per session. That's 5-10 DKK. Compare that to a gym at 300-500 DKK/month or a public sauna at 75-100 DKK per visit.

How long does it take to warm up?
15-30 minutes depending on size and weather. Glöd is fastest (15-20 min), Elda takes 15-30 min.

Can you use it in winter?
Yes. The three-layer construction retains the heat. It just takes 5-10 extra minutes to warm up in the cold. Many people actually think it's best in winter — the contrast between heat and cold air is incredible.

How long does a sauna tent last?
5-10 years with proper maintenance. Leave the tent open for 15-20 minutes after use so it dries. Store it dry. Never roll it up while damp.

Is it dangerous?
Not if you follow the instructions. Use it outdoors only. Keep the ventilation openings open. Have water nearby. Keep children and pets away from the stove. Never use the sauna completely alone.

Can you stand upright in the tent?
Yes, both models have full standing height.

Do you need a building permit?
No. A sauna tent is a temporary structure without a foundation and requires no permit in Denmark.

How much firewood do you use?
3-5 kg per sauna session of 60-90 minutes. Birch is recommended. A session costs about 5-10 DKK in firewood.

What's the difference between Elda and Glöd?
The size. Elda is for 4-10 people. Glöd is for 2-6 people — more compact, faster warm-up. Both use the same stove, same materials, same quality.

Can I use the sauna tent at a campsite?
Most campsites allow it, but always ask first. Keep 2 metres distance to other tents and buildings.

What do I do if it rains?
Use the sauna anyway. Rain actually makes it extra cosy — you sit in the warmth and hear the rain on the tent. The tent is waterproof. The stove is inside the tent. No problem.

Can I rent a sauna tent before buying?
We don't offer rentals, but you have a 101-day return policy. Read more about the terms on our returns page.

Conclusion — is a sauna tent worth it?

Yes. The short answer is yes.

5-10 DKK per session. 5 minutes to set up. No building permit. No installation. And health benefits documented in decades of Finnish research.

Smelt Elda is rated the best sauna tent in test by Friluftsfreak.dk. It gives you room for family and friends, full standing height, and a sauna that reaches 80-100°C in 15-30 minutes.

Glöd gives you the same in a compact size — perfect for couples and small groups, with faster warm-up.

Both models have three-layer construction in Oxford 300D polyester, a stainless steel wood-burning stove, Danish customer service, and spare parts in stock.

It's a sauna you can take with you. To the garden, the cabin, the campsite. And 15 minutes in the heat after a long day — it just changes everything.
