Who it fits
Good fit for
This sauna suits households with four to six members who want versatility in their heat therapy. The hybrid design is ideal for users who enjoy both dry infrared sessions and traditional steam relaxation. The smart controls are perfect for those who prefer adjusting settings remotely. The corner layout works well for families with limited floor space but high capacity needs. It is also good for athletes or wellness enthusiasts seeking a premium, all-in-one home spa experience with included accessories.
Who should skip it
Look elsewhere if you need a single-mode sauna. You cannot run infrared and steam simultaneously; the modes must be used separately. This unit is not for small spaces, as the 78.8-inch square footprint requires significant corner clearance. Avoid it if you prefer cedar wood, as this model uses hemlock. Also, note that the long table on the right is a storage shelf, not a seat. If you need a compact unit for three people or fewer, consider the smaller variations.
Verdict: The Smartmak hybrid corner sauna offers versatile dual-therapy options in a spacious hemlock build. It is best for larger households seeking remote-controlled, multi-mode heat experiences.
Key specs explained for Smartmak
Heating Type: Hybrid (full-spectrum infrared + steam)
This unit offers two distinct heating modes in one cabinet. You can choose far-infrared dry heat or traditional steam therapy. The listing states these modes must be used separately, not simultaneously. This flexibility lets you switch based on your preference or health needs. It suits buyers who want the benefits of both infrared and Finnish-style saunas without purchasing two separate machines.
Heater Power: 3.5KW infrared, 6KW steam stove
The infrared section uses 3.5KW of power, while the steam section uses a 6KW Harvia stove. Higher wattage generally means faster heating and the ability to maintain temperature in larger spaces. The 6KW steam stove heats rocks quickly for traditional steam sessions. This power level supports the unit’s 5-6 person capacity, ensuring the space reaches optimal temperatures efficiently for multiple users.
Max Temperature: 149°F infrared, 195°F steam
Infrared mode reaches up to 149°F, while steam mode goes as high as 195°F. The higher steam temperature mimics traditional Finnish sauna conditions. This range allows you to customize intensity. Lower temperatures are often preferred for longer, relaxing sessions, while higher heat suits those seeking deep muscle relaxation. Check if your health conditions allow for temperatures near the 195°F maximum.
Dimensions: 78.8"W x 78.8"D x 82.74"H
The footprint is roughly 79 square feet, fitting into a corner layout. The height is just over 6.8 feet. This size accommodates 5-6 adults comfortably, according to the listing. Ensure your room has enough clearance for the panoramic door and ventilation. Measure your space carefully, as the square design requires equal width and depth on two adjacent walls for proper installation.
Control Type: WiFi, Bluetooth
You can adjust temperature, lighting, and audio via a smartphone app. Bluetooth connects your device for audio playback. This remote control lets you start sessions before entering, saving warm-up time. It also allows you to manage settings without leaving the heat. This feature is ideal for users who value convenience and want to integrate the sauna into a smart home routine.
Design and build details
The Smartmak sauna uses Canadian Hemlock wood for its construction. This material choice affects both the interior scent and the durability of the cabinet. The listing specifies a corner design with a square footprint of 78.8 inches by 78.8 inches. The height is listed at 82.74 inches. This shape allows you to fit the unit into a room corner, saving floor space compared to a rectangular layout. The panoramic glass door provides visibility and airflow. You should note that the long table on the right side is a storage shelf, not a seat. This affects how you arrange your seating and towels inside.
Control is managed via WiFi and Bluetooth. You can adjust temperature, lighting, and audio remotely through a smartphone app. The listing mentions a 3D surround sound system and seven-color chromotherapy lights. These features are built into the cabin structure. An air purifier is also included to maintain air quality during sessions. The heater power is split between a 3.5KW infrared system and a 6KW steam stove. The infrared mode reaches up to 149°F, while the steam mode goes up to 195°F. According to the listing, these two modes must be used separately. You cannot run both heating elements at the same time. This separation simplifies the electrical setup but limits simultaneous therapy options. The finish is natural Hemlock, which requires standard maintenance to keep the wood looking clean.
Setup and daily operation details
Setting up this corner unit requires planning for its 78.8-inch by 78.8-inch footprint. The square base fits well into a room corner. You must ensure the location has adequate electrical support for the 3.5KW infrared system and the 6KW Harvia steam stove. These components draw significant power. The listing notes that the long table on the right is a storage shelf. You cannot sit or lie on it. This affects how you arrange the interior space for five or six people.
Daily use begins with connecting the unit to your home network. The WiFi and Bluetooth controls allow you to adjust temperature and lighting from a smartphone. You can manage the 3D surround sound and seven-color chromotherapy remotely. The air purifier runs to keep the air fresh during sessions. You must choose one heating mode at a time. The infrared mode heats up within 10 to 15 minutes, reaching up to 149°F. The steam mode uses the 6KW stove to heat rocks, reaching up to 195°F. You cannot use both simultaneously.
Before starting steam mode, you fill the water bucket and use the provided spoon to pour water onto the rocks. The timer lets you set session length. After use, you wipe down the Hemlock wood. The panoramic glass door allows you to see out while you relax. The design prioritizes airflow through ventilation features. You manage everything through the app or the internal controls. The system handles the heating and audio settings for you.
Key Considerations For Owners
Before you commit to this Smartmak hybrid sauna, verify your home’s electrical capacity. The 6KW steam stove and 3.5KW infrared heaters require dedicated circuits. You must confirm your panel can handle this load safely. Check your corner space for the 78.8-inch square footprint. Ensure the 82.74-inch height fits your ceiling clearance. This unit uses Canadian Hemlock, which needs occasional oiling to maintain its appearance and prevent drying. The dual-system design means you cannot run both modes at once. Plan your sessions around this limitation. You will need to supply your own sauna rocks and water for steam mode. The included accessories cover most basics, but verify compatibility with your existing WiFi network for the smart controls. Compared to other 1 options here, this model stands out for its corner efficiency and dual therapy. However, the requirement to switch modes separately may inconvenience users who prefer rapid transitions. Ensure this operational style matches your wellness routine before purchasing.
Check before you buy
- Verify electrical panel capacity for 6KW steam and 3.5KW infrared loads.
- Measure corner space for the 78.8-inch square footprint and height.
- Confirm WiFi network compatibility for smart control features.
- Plan for separate use of infrared and steam modes.
- Prepare for regular Hemlock wood oiling and maintenance.
