How To Choose The Best Cheap Saunas
A portable sauna is a tent with heaters and a chair, but build materials, heat type, and interior room separate a relaxing session from a frustrating one. Here is what to look for before you add to cart.
Far Infrared vs Steam: Which heat fits your life?
Far infrared saunas use carbon or ceramic panels that warm your body directly without heating the air around you the same way. You feel the heat sooner, and cleanup is usually just a towel wipe because there is no steam vapor. Steam saunas, by contrast, fill the tent with humid air (near 100% humidity) using a water pot and a heating element. They feel denser and hotter on the skin but create condensation that you must wipe down after every session. If you want a quick, dry sweat, pick infrared. If you love that thick, enveloping steam room feeling at the gym, go steam.
Material quality: The insulation and frame matter
The cheapest tents use a single layer of polyester. Better budget models use 5-layer waterproof insulation — like the iTHERAU or KASUE — that locks in heat and prevents moisture from soaking through the walls. The frame is equally important: stainless steel pipes resist rust better than standard steel. Check the number of tubes. The Morfone, for example, uses 24 reinforced tubes for stability. A wobbly frame in a cheap sauna is a deal-breaker because it makes the whole tent feel cheap.
Size and capacity: One person is not the same as two
A 1-person sauna like the Kanlanth wood cabin measures 36.6 x 29.3 inches in footprint — tight but private. A 2-person tent like the iTHERAU or KASUE runs about 49 x 36 inches at the base and 71 inches tall. That extra width lets you sit side by side without your shoulders touching. If you are taller than 5’10”, look for a tall tent around 71 inches and verify from reviews that real tall users fit without slouching.
Red light therapy: A bonus worth the upgrade
Some cheap saunas now include red light therapy panels (660nm wavelength for skin-level benefit, deeper 850nm for muscle penetration). If you suffer from post-workout soreness or general muscle tension, a sauna that pairs heat with red light (like the iTHERAU or Morfone) may replace two separate devices in your home. The trade-off is that red light panels add to the price tag. Decide if that matters before you filter.

In‑Depth Reviews
1. iTHERAU 2 Person Infrared Sauna Box
A two-person tent that packs a dual steamer and red light therapy into a wallet-friendly package.
You get a spacious interior (49 x 36 x 71 inches) big enough for two adults to sit side-by-side on the included folding chairs without feeling cramped. The 29.3-pound frame weighs more than the Portable Pentagonal sauna at 23.9 pounds, which can suggest more substantial material when you zip yourself in.
Two 1400W steam generators with 3L water capacity each send 360° steam through the cabin in minutes. Buyers report the dual steamer setup “def gets this thing going,” with one reviewer hitting 117°F and 100% humidity in a 60°F garage. On top of the steam, you get 660nm + 850nm red light therapy panels — the 660nm wavelength targets surface-level muscle tension while the deeper 850nm penetrates for joint recovery. That combination is rare at this price point. The trade-off: owners mention the included chairs are short, so taller users might want to swap them out for a sturdier foldable seat. The 5-layer waterproof insulation keeps heat locked in without condensation leaking through the walls, and the double zipper lets you open a transparent window for fresh air mid-session.
At 29.3 pounds it is not the lightest tent to drag from the closet to the living room, but the stainless steel frame resists corrosion and the fabric wipes clean in seconds.
What earns the top spot
- Dual 1400W steamers fill the tent fast with dense 360° heat.
- 660nm + 850nm red light therapy is included at a budget-friendly price.
- 5-layer waterproof insulation holds heat efficiently during 60-minute sessions.
- Generous 71-inch height lets most adults stand up straight inside.
The honest trade-offs
- Included chairs are short according to several tall-user reviews.
- At 29.3 pounds, it is heavier than the 23.9-pound Pentagonal alternative.
- Reviewers caution the zippers may wear over time with frequent use.
Who this fits: Anyone who wants a two-person steam sauna with red light therapy at a price that undercuts standalone light panels.
One real limitation: The short chairs mean taller users should plan to bring their own seat for comfort.
2. MIXC Upgraded Low EMF Infrared Sauna Box
A tall, narrow infrared tent that heats your core without filling the room with steam.
You avoid steam cleanup entirely with the MIXC. It delivers a dry far infrared experience through three carbon crystal heating panels and one LED warm light. Because there is no water vapor, you just wipe sweat off the waterproof fabric — no condensation dripping down the walls. The interior footprint measures 31.5 x 31.5 inches, which is tight for one person but frees up floor space compared to the iTHERAU’s 49 x 36-inch base. That means a 31.5 x 31.5-inch footprint versus the iTHERAU’s 49 x 36-inch base, which is significant if your apartment or home gym is tight on room.
The 28.7-pound frame uses 19 stainless steel pipes that resist high temperatures and corrosion, and the detachable design folds down for carrying between rooms. A built-in foot heating pad ensures your feet soak up infrared warmth alongside your torso. The control panel lets you set session times from 20 to 60 minutes, and an overload protection system adds a safety layer during use. Since this is a dry heat tent, there is no humidity buildup — so it is better for users who find steam suffocating. The trade-off: without steam or red light, this is a straightforward heating experience. You are paying for reliable far infrared heat at an entry-level price, not luxury extras.
Why this is a solid solo pick
- Three carbon crystal panels heat up without creating messy steam or condensation.
- Wipes clean in seconds — no water to drain or vapor to air out after each session.
- Detachable frame folds flat for storage in a closet or under a bed.
- Foot heating pad warms your feet evenly while your core heats up.
What you give up
- No red light therapy or dual-heat options — pure infrared only.
- 31.5 x 31.5-inch footprint is tight; larger users may feel confined.
- Heating time is slower than a dual-steamer setup like the iTHERAU.
Best suited for: Someone who wants a low-maintenance, dry infrared sweat session without dealing with steam cleanup.
Skip this if: You want steam, red light therapy, or room to stretch out — look at the iTHERAU instead.
3. Portable Full Size Infrared Sauna (Pentagonal)
A five-sided sauna that wedges into a corner and weighs less than most carry-on luggage.
At 23.9 pounds, this Pentagonal sauna is the lightest in the mid-range group at 23.9 pounds versus the iTHERAU at 29.3 pounds, making it the easiest to lift, fold, and carry from storage to your living room or bedroom. The unique pentagonal shape is designed to nestle into a room corner, so it takes up less visual and physical space than a square or rectangular tent. The interior measures 37.5 x 31.5 x 62.5 inches, which gives you enough room to sit on the included folding chair with a foot heating pad warming your feet.
The far infrared heating system uses new carbon crystal panels that reach up to 140°F (the maximum temperature depends on your room environment). You control the time up to 60 minutes and the temperature via a wired remote control panel. A one-year warranty backs the purchase. The trade-off: the pentagonal geometry means less shoulder room than a square tent of similar specs, and the 62.5-inch height is shorter than the 71-inch iTHERAU — so taller users will have limited headroom. If you are 5’8″ or under and privacy is your priority, this is a clever way to own a sauna without dedicating floor space.
What stands out
- Weighs only 23.9 pounds — easiest tent here to carry between rooms.
- Pentagonal design fits snugly into a corner to save floor space.
- Carbon crystal panels heat up efficiently and reach up to 140°F.
- Includes foot heating pad and folding chair for a complete setup.
The compromises
- 62.5-inch interior height is short; users over 5’8″ may crouch.
- Pentagonal shape means less shoulder width than a square tent.
- No red light therapy or dual steamers — basic far infrared experience.
Reach for this if: You are short on floor space and need a lightweight sauna that folds away fast.
Look elsewhere if: You are over 5’8″ or want room to stretch your arms — the iTHERAU is taller and wider.
4. KASUE Upgraded 2 Person Sauna Box
An 80-inch-tall cabin with two separate steam generators that fill the space fast and hot.
Even a 6’4″ user can stand up straight in the KASUE without their head brushing the ceiling. It is the tallest tent in this lineup at 80 inches — a full 9 inches taller than the iTHERAU’s 71 inches — and the interior footprint measures 40 x 40 inches at the base, giving both occupants more generous shoulder room than the MIXC’s 31.5-inch-wide setup. Two 3L steam generators work in parallel with a 360° array of densely packed steam outlets, so the cabin fills with enveloping heat in minutes.
Like the iTHERAU, this model includes 660nm red light therapy for deep tissue penetration, targeting muscle soreness and post-workout repair. The 5-layer waterproof material traps heat effectively while blocking moisture from seeping out. A built-in storage pouch holds your phone and glasses, the double zipper makes entry smooth, and a transparent window lets you vent without unzipping entirely. Customers note the chairs are functional but basic — do not expect ergonomic support. The remote control lets you adjust temperature and timer without reaching for a panel. At 28.3 pounds, it is nearly identical in weight to the iTHERAU, so portability is similar. The trade-off: the packed dimensions are bulkier than the MIXC or Pentagonal tents, so storage space needs to be larger.
The strong points
- 80-inch height fits tall users up to about 6’4″ without crouching.
- Two 3L steam generators deliver rapid heat through 360° steam outlets.
- 660nm red light therapy supports muscle recovery during steam sessions.
- 5-layer waterproof construction locks in heat and wipes clean easily.
What to consider
- Bulky when folded — needs a larger closet or storage area than smaller tents.
- Included chairs are basic and may not suit taller or heavier users.
- No 850nm red light wavelength for deeper joint penetration like the iTHERAU.
Ideal for: Tall users who cannot fit in a standard 71-inch tent and prioritize headroom above all else.
Skip it for: Smaller apartments where storage is tight — the folded size is noticeably larger than the Pentagonal or MIXC.
5. Homedics Portable Steam Sauna
A collapsible steam tent that pops open in under one minute and weighs just 13.7 pounds.
The Homedics is the lightest sauna here at 13.7 pounds versus the next lightest at 23.9 pounds, and its collapsible pop-up frame means you can go from storage bag to sitting inside in under one minute. The steam generator takes 10 to 15 minutes to fill the tent with near-100% humidity at temperatures up to 115°F. While that max temperature is cooler than the 140°F some infrared models reach, the high humidity makes the heat feel dense and enveloping on your skin, similar to a traditional steam room.
At 35.43 x 35.43 x 57.87 inches, the interior is compact — best suited for a single person sitting on the included foldable chair. The 57.87-inch height is the shortest in this roundup, so if you are over 5’7″ your head will touch the top. The waterproof interior locks in heat and the polyester/polypropylene construction is durable enough for regular use. Homedics backs it with a 1-year limited warranty. The trade-off is that 115°F is limiting if you are used to hotter sauna sessions at the gym. This is a gentle, relaxing steam experience, not an intense sweat lodge.
What makes it unique
- Sets up from bag to tent in under one minute with a pop-up frame.
- 13.7 pounds is extremely portable — easy to pack for trips or move room to room.
- 100% humidity steam at 115°F provides a traditional steam room feel.
- Folds into a storage bag roughly the size of a carry-on suitcase.
Where it falls short
- 115°F max temperature is lower than the 140°F of the infrared Pentagonal tent.
- 57.87-inch interior height is very short — tall users will not fit comfortably.
- No red light therapy or infrared panels — pure steam only.
Great for: Travelers, apartment dwellers, and anyone who wants a quick steam session without permanent setup.
Not for: Tall users (over 5’7″) or anyone who expects high heat above 115°F.
6. SAUNABOX SmartSteam Pro Kit
A steam tent with seven heat levels and a 0–60 minute timer for pinpoint session control.
You can fine-tune your session intensity instead of relying on a single temperature setting. The SAUNABOX offers 7 adjustable heat levels and a full timer range from 0 to 60 minutes — so you dial in exactly how hot and how long you want to sweat. It reaches up to 140°F (60°C) in about 15 minutes at nearly 100% humidity, rivaling the max heat of the far infrared Pentagonal sauna in a steam format.
At 34.6 pounds, it is the heaviest tent in this comparison at 34.6 pounds versus the 23.9-pound Pentagonal, and that weight comes from a thick ThermoShield insulated cover and a sturdy pop-up frame that assembles in about 10 minutes without tools. The complete kit includes a SweatLock floor mat, a portable chair, a waterproof phone holder, and a towel hook. The VOC-free materials mean you do not get chemical smells during heat-up, a common complaint with cheaper polyester tents. The trade-off: the weight and packed size make this less portable than the Homedics or Pentagonal models. It is better as a semi-permanent home setup than a travel companion.
Why it stands out
- 7 heat levels and a 0–60 min timer give precise control over your session.
- Reaches 140°F (60°C) in about 15 minutes with nearly 100% humidity.
- ThermoShield insulated cover and SweatLock mat prevent heat and moisture loss.
- VOC-free materials reduce chemical off-gassing during heating.
What holds it back
- 34.6 pounds is heavy — this is not a tent you want to move daily.
- No red light therapy or far infrared panels — pure steam experience.
- Assembly takes about 10 minutes; not as instant as the pop-up Homedics.
Pick this one for: A dedicated steam room setup in a home gym where you value heat customization over portability.
skip it if: You need a lightweight, packable sauna for travel or small apartments.
7. Morfone 2 Person Portable Infrared Steam Sauna
Sturdy stainless steel frame with 24 tubes plus two steamers and 660nm red light panels.
Frame stability is the Morfone’s headline. It builds on the same 49 x 36 x 71-inch dimensions as the iTHERAU, so two adults can sit together with the same footprint. what separates it is the frame: 24 reinforced stainless steel tubes, up from the standard 19 or 20 tubes on other midsize tents. That extra steel means the tent feels more rigid when you step inside or move around, and it should resist sagging over months of use. The high-density multi-layer waterproof insulation material matches the 5-layer build of the iTHERAU and KASUE, so heat stays inside.
Two XL steam pots with 9 temperature settings provide the heat, and the 360° steam head distributes vapor evenly through the cabin within about 10 minutes. The 660nm red light therapy panel adds cellular-level warmth for muscle relaxation. Reviewers point out that setup takes about 10 minutes solo (easier with two people) and that the sauna “works flawlessly” even after a month of regular use. The honest review catch: one reviewer noted a steamer stopped working on first use, so quality control may vary. The remote control makes adjusting temperature and time convenient without unzipping the door. Two clear detachable windows let you look out or let in fresh air.
What makes it a contender
- 24 reinforced stainless steel tubes for above-average frame stability.
- Two XL steam pots with 9 temperature settings for granular heat control.
- 660nm red light panel adds wellness benefits beyond plain steam.
- Heats up in about 10 minutes according to manufacturer and user reports.
What to watch out for
- One verified review reported a steamer failing on the first session — check warranty coverage.
- Assembly is slightly difficult solo; easier with a second person.
- No 850nm red light wavelength for deeper joint penetration like the iTHERAU.
Grab this if: Frame stability is your top priority and you prefer a tent that feels solid when you move inside.
pass on it if: You want the deepest red light therapy (850nm) or the simplest solo assembly experience.
8. Kanlanth 1 Person Far Infrared Wood Sauna
A real spruce wood cabin for one person that plugs into a standard wall outlet without special wiring.
You get the look and feel of a permanent sauna at a fraction of the size. Unlike every other sauna on this list, the Kanlanth is not a fabric tent — it is a solid wood cabin made from selected Spruce. The footprint measures just 36.6 x 29.3 inches, making it the most space-efficient design for a single user who wants a dedicated sauna corner in a master bath or home gym. The vertical design gives you a cozy, private sanctuary without the tent-flapping feeling of polyester walls.
Five high-performance far infrared epoxy panels generate the heat, reaching up to 140°F (60°C) while drawing only 950W — low enough to run on any standard 120V/15A household outlet with a 2.2-meter power cord. You do not need an electrician or a dedicated 40-amp circuit like a full-size wooden sauna requires. Built-in Bluetooth speakers pair with your phone for music, and an LED reading light lets you bring a book inside. The button control panel adjusts time and temperature simply. A 110°C safety overheat protection sensor and a built-in ventilation port keep air circulating. The trade-off: at this price point in the lineup, you get no steam, no red light therapy, and a very tight single-person interior — you sit, you sweat, you leave. For some, that minimalism is exactly the point.
Why the wood cabin wins
- Solid Spruce wood construction looks and feels premium compared to fabric tents.
- Plugs into any standard 120V/15A outlet — no electrician or special wiring needed.
- Bluetooth speakers and LED reading light add entertainment during sessions.
- Five far infrared epoxy panels heat up to 140°F with low 950W power draw.
Where it is limited
- 36.6 x 29.3-inch interior is tight — you sit upright with minimal room to move.
- No steam, no red light therapy — this is a dry far infrared experience only.
- Heavier and less portable than any fabric tent — essentially a piece of furniture.
Choose this for: The look and durability of real wood in a tiny footprint, with simple plug-and-play installation.
Pass on this if: You want steam, red light, or room to stretch out — a tent-style sauna gives you more flexibility.
Understanding the Specs
Far Infrared vs Steam Heat
Far infrared uses carbon crystal or epoxy panels that warm your body directly by emitting infrared waves. The air inside stays cooler, so you sweat from the inside out without feeling suffocated. Steam saunas use a water-filled pot with a heating element that boils water into vapor, filling the tent with humid air (near 100% humidity). Steam feels thicker and hotter on the skin but creates condensation that you must dry after each session. Your choice depends on whether you prefer a dry, direct heat (infrared) or a wet, enveloping heat (steam).
Red Light Therapy Wavelengths
660nm (nanometer) red light penetrates the outer layers of your skin to support surface-level muscle relaxation and skin health. It feels like a gentle warmth on your skin during a sauna session. 850nm near-infrared light reaches deeper into muscle tissue and joints for recovery below the skin’s surface. The iTHERAU includes both 660nm and 850nm panels, while the KASUE and Morfone offer 660nm only. If you suffer from joint soreness after workouts, the dual-wavelength option is worth the premium.
Insulation Layers and Heat Retention
The number of material layers directly affects how fast your sauna heats up and how long it stays hot. A 5-layer waterproof construction (found on the iTHERAU, KASUE, and Morfone) traps heat inside while preventing moisture from seeping through the fabric. Single-layer tents lose heat faster, which means the heating element runs longer to maintain temperature. More layers also make the tent heavier and less portable — note the 34.6-pound SAUNABOX versus the 13.7-pound Homedics.
Timer Range and Temperature Control
Standard budget saunas offer a 20-to-60-minute timer and a single temperature setting. The SAUNABOX steps up with 7 heat levels and a 0–60 minute timer for customizing each session to your tolerance. Saunas with wired or remote control panels let you adjust mid-session without unzipping the door — a small convenience that matters when you are already sweating. Models without remote control require you to reach for a panel near the steam entry, which can be awkward mid-session.
