Everything an Electric Sauna Needs, in One Box
An electric heater is usually the practical fit where reliable electrical service is available and you want automatic temperature control: flip a switch (or tap a phone app) and the thermostat holds the temperature, with no fuel to store, no ash to sweep, and no chimney to maintain. Harvia's manuals put heat-up at about an hour for a correctly sized heater in a properly insulated room. But the heater alone won't get you there. You need stones in the basket, a controller to hold temperature, and the right 240V circuit feeding it.
That's what these packages handle. Each Complete Package bundles the electric heater, a pre-measured load of olivine diabase stones, and the matching controller — with WiFi control included on most models — sized to work together the day it arrives. This is the electric-only cut of our broader heater package hub; if you want wood-burning kits in the mix, start there instead.
240V, a Dedicated Circuit, and Why It Comes First
Almost every heater in this collection runs on 240V single-phase — the same voltage as your electric dryer or range. The catch is that it needs its own dedicated circuit on its own breaker, not a shared one and not a plug. Before you settle on a wattage — from a compact unit to a larger heater like the HUUM STEEL 10.5kW — check that model's own electrical specifications. Phase is set per model: the Harvia Club comes in 240V single-phase and 208V three-phase versions, while the HUUM HIVE 12, 15 and 18kW are single-phase heaters (240V or 208V) connected on two circuits.
Current draw can be estimated from heater output and voltage, but breaker size, conductor size and circuit configuration must be taken from the installation manual for the specific heater. Two heaters with the same kW rating can have different electrical requirements. Every Topture heater page lists the manufacturer specifications for that model. Final installation must be verified by a licensed electrician.
None of this is a DIY job. A licensed electrician has to confirm the breaker size, run the correct wire gauge, and verify your panel has the headroom — and they'll do it for your specific home, not a generic spec sheet. Our guide to sauna electrical requirements walks through the rough-in planning you'll want to do before you get a quote. Settle the circuit before you settle the heater location, especially outdoors.
Controllers and WiFi: What You're Actually Getting
The controller is the part buyers most often forget when they price a bare heater. Every package here includes the right one. Harvia's external packages use the Xenio digital controller; the Virta Combi steamer models need the controller that runs the water reservoir separately from the dry heat. Every HUUM heater requires the separate UKU controller, which is built into the HUUM bundles. Saunum packages include Saunum's AirIQ WiFi control, the only control Saunum approves for its heaters.
WiFi control is included on most electric packages in this collection, which means you can set temperature, run a timer, and schedule recurring sessions from the brand's phone app — so the sauna is at temperature by the time you walk out to it. The handful of Harvia KIP built-in models keep it analog with a simple dial on the unit, which is the cheapest, most maintenance-free path if you don't care about app control. If app control is the priority, cross-shop the full WiFi-enabled heater selection.
Stone Capacity — The Spec That Decides Steam Quality
More stones means more thermal mass, which means softer, longer-lasting löyly when you pour water across them instead of a sharp, dry blast that fades fast. This is where the brands separate. Harvia's wall-mounted KIP holds 44 lbs; the Virta steps up to 110 lbs (154 lbs at 10.5kW) and the Cilindro column to 264 lbs. HUUM goes heavier still — the HUUM CLIFF 6kW carries 165 lbs in a slim column, and the floor-standing HIVE 12kW holds up to 551 lbs (250 kg), the most of any electric heater Topture stocks.
The packages ship the stones pre-measured for the specific heater, so you're not guessing at quantity. Olivine diabase is the rock to use — split-face volcanic stone that holds heat and shrugs off the thermal cycling that cracks cheap landscape rocks. Need to top up down the road?

Sizing the Wattage to Your Room
Measure the interior of your sauna in feet (length × width × height) to get cubic feet, add the allowance the heater's manufacturer publishes for glass and other uninsulated surfaces, and choose a heater whose rated room range contains the result. Harvia's manuals add 1.2 m³ per m² — about 3.94 cu ft for every square foot of glass, stone, tile or concrete — and multiply a log sauna's volume by 1.5; HUUM's manuals add 3.3 cu ft per square foot. A 7×7×7 room is 343 cubic feet: heaters rated for that include the HUUM DROP 7.5kW (248–389 cu ft), the Harvia KIP 8kW (250–425) and Virta 8kW (177–431), and the 9kW HUUM (283–460) and Harvia Virta (177–494) models. Topture's heater size calculator does the arithmetic, and the manufacturer's rated range is final. Manufacturer-rated ranges for packages in this collection:
-
Up to about 250 cu ft: HUUM CLIFF Mini and STEEL Mini 3.5kW (106–177 cu ft), Harvia KIP 4.5kW (100–210), HUUM DROP 4.5kW (106–248), Saunum Air 5 (106–212)
-
About 170–320 cu ft: 6kW — Harvia KIP 6kW (170–300), Harvia Virta 6kW (177–294), HUUM DROP, CLIFF, STEEL and HIVE Mini 6kW (177–318)

If you'd rather assemble your own setup from a bare heater and choose the controller and stones yourself, the parent electric sauna heater collection has every model unbundled. And if you're still weighing brands, the design-driven Saunum lineup brings a climate equalizer that evens out the temperature between the lower bench and the ceiling — worth a look if you've ever sat in a sauna with hot shoulders and cold feet.
Wall-Mounted vs. Floor-Standing in This Collection
The form factor changes more than where the heater bolts. Wall-mounted units — the Harvia KIP, the HUUM DROP, and the Saunum Air and Air L — free up floor space and heat fast, which makes them the right call for tight indoor rooms. Floor-standing units — the Harvia Virta, Cilindro and Club and the HUUM CLIFF, STEEL, HIVE Mini and HIVE — carry the deepest stone baskets in the lineup, and that thermal mass is what produces the softest, steamiest löyly. The HUUM CLIFF Mini and STEEL Mini sit in between: they stand on legs but are only 6.3 in deep. If floor space is the constraint, go wall-mounted; if steam quality is the priority and you have the room, the floor models earn their footprint.
One more practical note for outdoor builds: an electric heater is fine outdoors as long as it sits inside an enclosed, ventilated sauna room with proper clearances — the heater doesn't go out in the open. What changes outdoors is the run to the panel. A detached sauna often means trenching conduit across the yard, heavier-gauge wire for voltage drop, and sometimes a sub-panel, which is exactly why the electrician quote should come before you pick the sauna's location.
What You Provide
The package covers the heater, stones, controller, and WiFi. You provide the enclosed sauna room itself, the dedicated 240V circuit installed by your electrician, and proper clearances and ventilation per the heater's spec sheet. Each product page shows its delivery method and estimate, and freight shipments are fully insured. Not sure which wattage your room calls for? Call us before you buy — getting the kW right the first time is the difference between a sauna that reaches temperature on schedule and one that never quite gets there.
