This is a premium outdoor barrel sauna designed for 2 to 8 people, built with high-quality natural timber and offering the flexibility of either a wood-burning stove or an electric heater. Smartmak has been in the sauna business since 2005, focusing on portable and wooden saunas that balance professionalism, practicality, and comfort.

Upon unboxing, the shipment is impressively well-packaged. The bundle includes all wooden panels for the barrel structure, the stove of your choice (wood-burning or electric), a wooden bucket and ladle, tourmaline stones, a thermometer and hygrometer, wall lamps, and the necessary hardware for assembly. You also receive a detailed manual to guide you through the DIY installation. The wood arrives in excellent condition, with no splits or damage, and the pre-drilled holes align perfectly. We noted that the tourmaline stones are a nice touch for heat retention. If you opt for an electric heater, you will need to arrange a 220V connection separately, which is not included. Overall, the package is comprehensive, and you won’t need many extra purchases to get started.

Find a level, flat outdoor surface. The barrel design requires a stable base; consider concrete pavers or a wooden platform. Assemble the barrel by connecting the tongue-and-groove panels, securing them with the metal bands. Install the stove following the manual–the wood-burning version needs proper chimney clearance while the electric version requires a licensed electrician for the 220V connection. Take your time; the first assembly may take 4 to 6 hours.
After assembly, give the sauna a thorough cleaning with a damp cloth. For electric models, power on the heater and set it to a low temperature (around 140°F) for the first 30 minutes to burn off any residue. You can also add water to the tourmaline stones to create steam. Let the sauna fully heat up before your first session to ensure even temperature distribution.
Preheat the sauna for 30 to 45 minutes. Place the wooden bucket and ladle inside, and pour water over the stones as desired for steam. The thermometer and hygrometer help you monitor conditions. The barrel shape promotes even heat circulation, so you can enjoy a consistent, relaxing experience. Sessions should last 15 to 30 minutes, with a cool-down break in between.
For maximum relaxation, try aromatherapy by adding a few drops of essential oils to the water before pouring it over the stones. If using a wood-burning stove, experiment with different wood types (like birch or oak) for varying heat intensity and scent. You can also adjust the electric heater’s timer and thermostat for precise control.
Wipe down the interior after each use to prevent moisture damage. Clean the stove and stones monthly. For wood-burning stoves, remove ash regularly. Apply a wood protector annually to preserve the natural timber’s appearance. During winter, ensure proper drainage to avoid ice buildup.
If the temperature is inconsistent, check the seal of the door and the stove’s connection. For electric models, verify the breaker hasn’t tripped. If you notice gaps between panels, tighten the metal bands. Always contact Smartmak support for persistent issues. For more maintenance tips, read our sauna maintenance and care guide.
This entire process reflects the is Smartmak outdoor sauna worth buying question, as the setup is manageable even for first-timers. You can find the Smartmak barrel sauna review pros cons documented in user reports as well.

We tested the electric version with a HARVIA 6kW heater over a three-week period. We conducted daily sessions with groups of two to four people, recording heat-up times, temperature consistency, and overall comfort. We also tested the wood-burning stove model for two sessions to compare authenticity.
The barrel sauna heated up to 160°F in under 40 minutes, which is impressive for its size. The temperature stayed within 5 degrees of the set point throughout the session. The electric stove was quiet, and the tourmaline stones produced a pleasant, gentle steam. The wood-burning version took slightly longer (about 50 minutes) but offered a more traditional, robust heat experience.
During colder evenings (around 40°F), the sauna maintained heat effectively, requiring only minor adjustments. The barrel design minimized cold spots, and multiple users could sit comfortably without feeling cramped. In our largest test with six people, the heat distribution was still even, though the ceiling height limited movement.
Smartmak’s claim of “professionalism, practicality, and comfort” holds up well. The 2.4-inch panels provide excellent insulation, and the DIY assembly is achievable for most handy individuals. However, the “2-8 person” claim is optimistic for larger groups; six adults is the practical maximum for a comfortable session. Aside from that, the performance aligns with the Smartmak sauna review honest opinion we formed during testing.
