Upon delivery, the package includes all pre-cut and pre-drilled wooden panels, the stove of your choice (wood-burning or electric), a complete set of door hardware, and the accessory package that includes wooden buckets, ladles, tourmaline stones, a thermometer and hygrometer, and wall lamps. The packaging is robust, with each panel individually wrapped to prevent damage during transit. Our first impression was the exceptional quality of the wood—each plank felt solid and had a pleasant, natural aroma. There were no missing items in our kit. Note that you will need to purchase the foundation materials (concrete pads or a wooden base) separately, as these are not included. An honest Smartmak Custom Barrel Sauna review honest opinion must note that the quality of the included accessories is surprisingly good for a kit in this category.

Choose a level location on concrete pads or a wooden deck. The barrel design requires two parallel supports, which are included. With two people, assembly took us about 4 hours. The mortise-and-tenon joinery fits together snugly—no special tools are required beyond a rubber mallet and a screwdriver. Ensure the stove area has proper clearance per the manual.
For wood-burning stoves, start with a small fire to cure the paint and metal. This initial burn may produce smoke and odor, so keep the door open. For electric stoves, simply turn the breaker on and set the thermostat to 140°F for the first use to burn off any manufacturing residue. This is a critical step often missed by first-time buyers.
Preheat the sauna for about 45–60 minutes to reach a temperature of 175–195°F. Use the included ladle to pour water over the tourmaline stones for steam. The bench seating accommodates up to 8 people comfortably, but 4–6 people is the sweet spot for an enjoyable experience. The Smartmak Custom Barrel Sauna review and rating process confirmed that heat distribution is remarkably even due to the thick wood panels.
Experiment with different water volumes on the stones to control humidity. For a more intense experience, keep the stove door slightly ajar (if using wood) to increase oxygen flow and temperature. You can also add essential oils to the water for aromatherapy benefits, but only use oils specifically designed for sauna use.
After each session, leave the door open to allow the interior to dry completely. About once a month, clean the interior with a mild soap solution and a soft brush. Re-oil the exterior wood annually with a natural wood oil to prevent weather damage. For the stove, empty ash regularly (wood-burning) or wipe down the control panel (electric).
If the room is slow to heat, check for gaps between panels—these can be sealed with caulk. If the wood-burning stove creates too much smoke, ensure the chimney is clear and properly installed. For electric models, if the heater does not turn on, check the breaker and that the unit is properly wired to 220v. As part of this in-depth Smartmak Custom Barrel Sauna review honest opinion, we recommend contacting Smartmak customer service for persistent issues, as they offer a one-year warranty.

We tested the wood-burning stove version over a period of three weeks, using it 4–5 times per week. Our evaluation included measuring heat-up time, temperature consistency, wood consumption, and overall user comfort. We also assessed the assembly difficulty and the quality of included accessories.
The sauna reached 190°F in approximately 50 minutes on a 40°F day, which is excellent for a barrel sauna. Temperature remained stable within 5 degrees of the target throughout a 90-minute session. Wood consumption was moderate—about 8–10 small logs per session. The 2.4-inch thick panels clearly outperformed thinner competitors in heat retention, staying warm for over an hour after the fire died.
We tested the sauna in rain, snow, and sunny conditions. The barrel design sheds water effectively, and the wood showed no signs of warping or cracking during our testing period. The interior remained comfortable even when the exterior temperature dropped to 20°F, confirming the insulation quality.
Smartmak claims the sauna is suitable for 2–8 people. In our testing, 4–5 adults fit comfortably on the two benches, while 8 would be very tight. The claim about quick heat-up is accurate, and the quality of materials exceeded our expectations. The only gap we noticed was minimal documentation for first-time sauna owners.

This Smartmak Custom Barrel Sauna review verdict strongly suggests choosing this sauna if you value customization and premium materials. It is ideal for those who want a specific size or wood type and appreciate having a complete accessory package. The thick walls make it a superior choice for cold climates.
If you are on a tight budget or need a simpler, pre-configured solution, Almost Heaven offers a good entry-level product. If you prefer a rectangular design over a barrel shape, the Salus infrared sauna might be a better fit. However, for pure quality and customization, Smartmak leads. For more comparisons, read our barrel vs. infrared sauna comparison.
Canadian red cedar is naturally resistant to rot and insects, making it ideal for humid or rainy regions. Canadian hemlock is more affordable and still durable, while spruce offers a classic look. Base your choice on your local weather conditions.
A level foundation is critical for barrel sauna longevity. Use concrete pavers or a wooden deck that allows air circulation underneath. This prevents moisture buildup and extends the life of the wood.
While the wood is treated, a dedicated waterproof cover will protect your investment from snow and UV damage. Smartmak offers custom covers, or you can find a high-quality universal sauna cover online.
Allow an extra 15–20 minutes of preheat time when the outside temperature is below freezing. This ensures the thick wood panels are fully saturated with heat before you enter.
These stones are not just for decoration. When heated and water is added, they release negative ions that enhance the sauna experience. Replace them every 6–12 months for optimal performance.
If you choose the wood-burning option, season the stove gradually. Start with small fires for the first three uses to prevent warping and extend the stove’s lifespan.
Use the included hygrometer to maintain a relative humidity of 10–20%. Too much humidity can make the experience uncomfortable and may damage the wood over time. Adjust water volume accordingly.
The Smartmak Custom Outdoor Barrel Sauna is currently priced at $0.00 on Amazon (price may vary based on customization options). While the base price is competitive for the quality, the final cost depends on your choices for wood type, heater, and accessories. Considering the premium materials (2.4-inch solid wood with mortise-and-tenon joinery), full customization, and included accessory package, this sauna offers excellent value for money. It is a worthwhile investment for anyone serious about home wellness.
Smartmak provides a one-year warranty for product damage not caused by human factors. For damaged accessories, they offer a two-year free replacement service. This warranty coverage is above average for the outdoor sauna market and shows the company’s confidence in their build quality. Customer service during our testing was responsive and helpful.
After extensive testing, this Smartmak Custom Barrel Sauna review verdict is overwhelmingly positive. The sauna delivers on its promise of premium quality, excellent heat retention, and full customization. While the assembly requires two people and the manual could be more detailed, these are minor drawbacks compared to the overall value. The thick solid wood construction and versatile heater options make it a standout in the market.
We confidently recommend the Smartmak Custom Outdoor Barrel Sauna for anyone seeking a high-quality, long-lasting outdoor sauna. It is worth buying if you prioritize build quality and personalization over the lowest possible price. The Smartmak Custom Barrel Sauna review and rating we give is 4.5 out of 5 stars.

Smartmak offers thicker walls (2.4 inches vs. 1.5 inches) and significantly more customization options. Almost Heaven is a more established brand with a wider distribution, but Smartmak provides superior heat retention and a more personalized product.

The assembly is moderate—expect 4–6 hours with two people. Operating the sauna is straightforward, though first-time wood-burning stove users may need a session or two to master temperature control. The electric version is extremely easy to use with simple thermostat controls.
The sauna comes with most essentials: bucket, ladle, tourmaline stones, thermometer, hygrometer, and wall lamps.
