Frequently Asked Questions

What type of sauna is the Cayenne?

The SunRay Cayenne 4-Person Outdoor Infrared Sauna HL400d is a Infrared (Far) sauna. Infrared saunas use panels to warm your body directly rather than heating the air. Sessions run cooler (130–150°F) but produce a similar therapeutic effect. It accommodates 4 Person and is built from Canadian Hemlock.

How much electricity does the Cayenne use?

The 2.1kW Carbon Nano Infrared requires a dedicated 240V circuit. Typical session consumption is 3–6 kWh depending on session length and ambient temperature. A licensed electrician should install the dedicated outlet before delivery — this is a one-time setup cost.

How long does assembly take?

Most Sunray models including this one use a pre-cut tongue-and-groove panel system. Two adults can typically complete assembly in 2–4 hours with basic tools. Full instructions and hardware are included. Video assembly guides are available from Sunray.

Can the Cayenne be placed outdoors?

Yes — this model is built for outdoor installation. Panels are weather-treated and the unit includes a shingled roof. Standard outdoor sauna precautions apply: level ground, clearance from structures, protected electrical outlet.

What is the Sunray warranty?

Sunray covers parts and labour for 1 year from delivery. RecovAthlete provides direct support for warranty claims — call 866-861-6317 or email us and we coordinate with the manufacturer on your behalf.

Do I need to do anything to maintain the sauna?

Wipe down benches and interior after each use. Sand canadian hemlock surfaces lightly if they show wear. Check door hinges and glass annually. For traditional models: clean the heater stones every 6–12 months and replace any cracked stones.

What is the difference between infrared and traditional saunas?

Traditional saunas heat the air to 150–170°F using a heater and rocks. You can add water to the rocks for steam (löyly). Infrared saunas use panels to emit radiant heat that warms your body directly at lower temperatures (130–150°F). Traditional is more intense; infrared is gentler and accessible for longer sessions. Both have documented wellness benefits.
