The Problem Saunum Set Out to Solve
You know that feeling when your shoulders are cooking but your feet are still cold? That's heat stratification, and it's the dirty secret of conventional sauna heaters. Hot air rises, so the band of air at the ceiling can sit dramatically warmer than the air down by the lower bench. You're technically in a hot room, but the heat isn't where your body is.
Saunum, an Estonian brand, built its heaters around fixing exactly that. Every package here includes a patented climate equalizer that actively circulates the air inside the sauna, pulling the warmth down and spreading the heat — and the steam — evenly from floor to ceiling. The result is heat that wraps around you instead of pooling above your head. If you've sat in a sauna and wondered why the experience didn't match the thermometer, this is the fix.
This collection is the bundled, ready-to-run version of Saunum's heaters. For the standalone heaters, equalizers, controls, and accessories, see the full Saunum brand collection.
What's in a Saunum Package
We carry two Complete Packages here, both built on the Air-series chassis with the climate equalizer integrated. Both ship with stones and Saunum's AirIQ WiFi control, both have a Himalayan salt feature with seven salt spheres included, and both accept an optional aromatherapy tray. Saunum's manuals give an operating range of 140–194°F (60–90°C).
The Saunum Air package ($4,465) is the smaller of the two, configurable at 4.8kW or 6.4kW with a heater that takes 110 lb (closed basket) or 130 lb (open basket) of stones according to Saunum's manual — sized for compact-to-mid home saunas. The Saunum Air L package ($5,630) scales up, available at 9.8kW, 13kW, and 15.2kW and a heater that holds 198 lb of stones, for larger rooms. Both heaters take water ladled onto the stones for steam on top of the equalizer.
Even Heat, Aroma, and Steam on One Unit
The equalizer is the headline, but the salt and aroma options are what make a Saunum session distinctive. The optional aromatherapy tray lets you add essential-oil scent into the circulating air rather than dripping it onto hot stones, and the Himalayan salt spheres sit in the air stream. Because the equalizer is moving air through the whole cabin, the aroma and steam distribute the same way the heat does — evenly, not in a cloud over the stones.
Both packages are externally controlled with WiFi, so you set temperature, run a timer, and start the heater from your phone before you head out to the sauna. If you want the equalizer effect in a sauna you've already built around a different heater, Saunum also makes standalone AirSolo equalizers — see the brand collection for those.
Who a Saunum Package Is For
Be honest about what bugs you in a sauna. If you've sat in plenty of them and never thought twice about the heat profile, a conventional heater will serve you fine and cost less. Saunum is for the person who's noticed the problem — the one whose feet stay cool while their face is roasting, or who's wondered why the lower bench feels like a different room than the upper one.
It also tends to land with buyers who care about the whole sensory session, not just the temperature: the aroma in the air, the steam, the feeling of being wrapped in even heat rather than baked from above. The salt feature, the aroma option and the equalizer working together are what deliver that. If a sauna is a daily ritual for you and the details matter, the Saunum bet pays off; if you just want a hot box on a timer, you can spend less elsewhere.
Sizing and How Saunum Compares
Size by room volume, using the ranges in Saunum's manuals: the Air 5 covers 106–212 cu ft and the Air 7 177–318 cu ft; the Air L 10 covers 247–459 cu ft, the Air L 13 317–565 cu ft and the Air L 15 459–741 cu ft. Measure the interior length, width and height in feet and multiply to get the volume.
The other heater brands Topture carries take different approaches: Finland's Harvia (Harvia packages) offers the widest range of sizes and fuel types, and Estonia's HUUM (HUUM packages) builds its heaters around large stone loads, with a UKU controller that can be set up to 230°F (110°C), or 194°F (90°C) with its bench sensor fitted; Harvia's Xenio and Saunum's own AirIQ go up to 194°F (90°C). Saunum's bet is on evenness — making the heat you already have feel better distributed rather than just hotter. If even löyly top-to-bottom is what you care about most, it's the one to look at. You can line all three up on our heater package hub.
Wiring and What You Provide
Both Saunum packages are externally controlled electric heaters that need a dedicated 240V circuit on their own breaker, sized to the wattage you choose — the 15.2kW Air L sits at the upper end and may call for a heavier circuit than the smaller Air. A licensed electrician must confirm the breaker, wire gauge, and panel capacity for your specific home before install; don't size the circuit off a generic chart. Our electrical requirements guide covers what to bring to that conversation.
The package covers the heater with its built-in equalizer, stones, Himalayan salt spheres and the AirIQ controller. You provide the enclosed sauna room, the circuit, and proper clearances per the spec sheet. These ship curbside freight, fully insured. Unsure whether the Air or Air L fits your room? Call us and we'll size it with you.
