The Equinox is Sun Home's full-spectrum infrared sauna line, manufactured by Sunlighten (Amplify series). Available in 2-Person and 3-Person configurations, the Equinox combines patented SoloCarbon® far-infrared heaters with full-spectrum panels for a complete infrared experience. Built-in chromotherapy and a premium Bluetooth sound system round out the cabin.
The Equinox runs on a standard 120V 20A circuit. No 240V wiring required. Do NOT install on a GFCI or AFCI breaker — these will trip during normal operation. See the electrical section below.

|---|---|---|
| Exterior Width | 50.9" | 62.3" |
| Interior Width | 45.4" | 56.8" |
| Bench Width | 45.2" | 56.6" |
| FIR Heaters | 4 | 5 |

Electrical Requirements
Both Equinox models share the same electrical setup:
- Voltage: 120V
- Wattage: 1,880W
- Amperage: 15.67A operating draw on a 20A circuit
- Plug: NEMA 5-20P (the wide-T-slot variant of a standard household outlet)
- Circuit: Dedicated 120V 20A — do not share with other appliances
Do NOT install the Equinox on a GFCI or AFCI breaker. The full-spectrum heaters can cause GFCI/AFCI breakers to trip during normal operation. A standard dedicated 20A breaker is the correct setup.

Installation Clearances
- Wall clearance: 4" minimum on all sides
- Ceiling clearance: 12" minimum above the sauna
- Recommended room size: 7 × 6 ft with an 8 ft ceiling
- Power cord: 10 ft, exits from the back left of the roof (facing the sauna)
Heating Performance
- Maximum temperature: ~155°F (typical operating temperature ~150°F)
- Heat-up rate to 135°F: roughly 1°F per minute from room temperature
- Heat-up rate above 135°F: 3–5 minutes per degree as the cabin approaches peak temp
- Time to peak temperature: ~2 hours of continuous operation to reach the upper end of the range
For most sessions, plan a 15–20 minute preheat to reach a comfortable operating temperature (130–145°F), then enjoy a 30–40 minute session.
Care and Cleaning
Both Basswood and Eucalyptus are naturally stable hardwoods well-suited to repeated heat cycles. To keep your Equinox in great shape:
- Wipe down the interior bench and floor with a clean towel after each session.
- Use the Sun Home Eco-Friendly Sauna Cleaner for deeper cleans — avoid solvents or bleach.
- Air out the cabin with the door open for 10–15 minutes after a session.
- Keep liquids off the heater panels.
