The picks
1. Sun Home Nova 3: best overall
The Nova 3 leads on heater, heat range and control. Its HUUM heater adds app-controlled preheat.
- Heater: HUUM DROP 6 kW electric heater, with remote preheat and scheduling in the HUUM app
- Heat: 230°F published maximum, with water on the stones for steam
- Size: 64.9 x 57.1 x 82.7 in
- Power: dedicated 240V, 30A circuit, hardwired by an electrician
- Build: Canadian cedar, two-level benches, carbonized hexagonal tile wall
- Warranty: limited lifetime on the cabin, with the heater under HUUM's warranty
Limits to know: it launched in July 2026, so independent reviews and owner history are still thin. Sun Home's guidance calls for 24 inches of clearance above the cabin, so measure your ceiling first.
Need more seats? The Nova 6 ($16,399 list) uses a 7.5 kW HUUM DROP on a 240V, 40A circuit.
2. Golden Designs Copenhagen Edition: best value
The Copenhagen delivers three seats, real stones and steam for $6,999.
- Heater: 8.0 kW electric stove with built-in controls
- Heat: 170 to 185°F ideal, up to 190°F
- Size: 79 x 59 x 83 in, about 675 lb
- Power: 240V, 40A for the stove, plus 120V, 15A for lights and audio
- Wood: Canadian red cedar interior, Pacific clear cedar exterior
- Warranty: 5 years electronics, 1 year stove
Limits to know: its footprint is larger than the Nova 3's for the same three seats, and it needs a 40A circuit.
3. Golden Designs Sundsvall Edition: best two-person
The Sundsvall is the compact choice at 60 x 46 x 83 in and 475 lb. It runs at 170 to 185°F on a 240V, 30A circuit and lists at $5,999. The two-person Hanko lists at the same price.
4. Golden Designs Osla Edition: best for six
The Osla seats six in a 79 x 72 x 83 in cabin weighing 715 lb. It runs at 175 to 190°F on a 240V, 40A circuit and lists at $8,499. The Engelberg Edition seats four to six for $7,499.
Need a built-in room? Saunass also sells Finnish Sauna Builders room kits in Western red cedar or thermo-treated poplar. A 3 x 4 ft room lists at $6,140.50 and an 8 x 9 ft room at $13,597.80. Ask Saunass what each kit includes before you order.
Why the Nova 3 ranks first
The Nova 3 leads the other three-person cabin on heat range, controls and warranty. The Copenhagen wins clearly on price.
| Factor | ||
|---|---|---|
| Heater | HUUM DROP 6 kW | 8.0 kW stove |
| Published maximum | 230°F | 190°F |
| Controls | Wi-Fi app with remote preheat and scheduling | Built-in controls on the stove |
| Circuit | 240V, 30A | 240V, 40A plus 120V, 15A |
| Floor area | 25.7 sq ft | 32.4 sq ft |
| Warranty | Limited lifetime cabin, HUUM heater warranty | 5 years electronics, 1 year stove |
| List price | $12,499 | $6,999 |
Choose the Nova 3 if remote preheating and its smaller published footprint fit your room and routine. Choose the Copenhagen if purchase price matters more and its larger footprint suits the space. Published maximum temperature is one specification, not a complete measure of comfort, steam quality or heating performance.
Evidence beyond specifications is still thin. The Nova 3's product page showed four owner reviews on October 2, 2026, and Sun Home says no independent hands-on review exists yet. Its heater has a longer record than the cabin: HUUM has sold the DROP for years, and Sweat Kingdom also offers it in its saunas.
Indoor installation requirements
An indoor traditional sauna needs four things from the room: power, a suitable floor, ventilation and headroom. Plan them before you order.
| Requirement | What to plan | Detail |
|---|---|---|
| Electrical | A dedicated 240V circuit installed by an electrician | Nova 3 and Sundsvall: 240V, 30A. Osla and Nova 6: 240V, 40A. Copenhagen: 240V, 40A for the heater, plus 120V, 15A for lights and audio. Confirm the exact model’s manual with the installer. |
| Floor | A level, water-resistant surface | Concrete, tile or laminate work. Avoid carpet and hardwood |
| Ventilation | Fresh air in and stale air out | Ask the seller where the vents sit and what the room needs |
| Headroom | Cabin height plus the maker's overhead clearance | Cabins here stand about 83 in tall |
| Moisture | A vapor barrier for built-in rooms | This applies to room kits more than freestanding cabins |
| Heat-up time | 30 to 60 minutes for most traditional saunas | Longer in a cold room or with more stone mass |
| Energy | About 7 to 9 kWh over two hours with a 6 kW heater | Harvia's example for an insulated 3 to 4 person sauna |
