• The Saunas can be placed on carpet, tiles, timber or concrete flooring.
• The surface the sauna is placed on ideally needs to be perfectly level, however if slightly out, levelling will be required.
• For the assembly process there needs to be adequate space around the sauna before it’s pushed into place.
• Clearance required is 3-5cm for the sides and top of the sauna.

Sun Stream Saunas heat up to 65°C, but unlike traditional saunas, far infrared saunas work by heating your body directly—not just the air. This radiant heat penetrates deeply to trigger a powerful detoxifying sweat at lower, more comfortable temperatures. Our saunas deliver faster, more effective results thanks to high-powered carbon heaters, full 360° heat coverage, and no fabric barriers over the panels.

A pre-heat time of only 15 minutes is all that is required to bring the heaters up to their full operating temperature prior to commencing your sauna session.

Yes. The Ascend 4‑Person Sauna is designed with spacious interior seating that can comfortably accommodate up to four adults. It’s a great choice for families, couples who enjoy shared wellness sessions, or anyone who values extra space during long sauna sessions.

The Ascend 4‑Person Sauna runs on a standard 240 V household outlet and draws approximately 9–10 amps, which is compatible with most standard 10 A circuits. For optimal safety and performance, we recommend using a dedicated circuit if other appliances share the same circuit. If you’re unsure about your home’s electrical setup, consult a qualified electrician to confirm capacity and outlet placement.

Infrared saunas are more efficient than traditional steam units because they heat the body directly rather than warm the air. The Ascend 4‑Person uses a modest amount of power (60 cents per hour) overall – comparable to everyday household appliances – and most customers find that running costs stay manageable even with regular use.

The cabin is made from premium Canadian Hemlock timber, which is stable, resilient, and naturally suited to infrared environments. The sauna avoids using plywood or particle board, and it uses safe, water‑based finishes to preserve a clean interior atmosphere.

The Ascend 4‑Person Sauna uses ultra‑low EMF and ELF heater technology. This means that electromagnetic and electric field exposure remains very low while still producing consistent, even infrared heat throughout the cabin.

Yes. The Ascend 4‑Person Sauna can be installed on a variety of stable indoor floors, including tiles, timber, carpet, and concrete. Just ensure the surface is level so the sauna sits securely and the door panels align properly.

No special tools are required. The sauna features an interlocking panel system, and most owners find that two people can complete assembly in under an hour with basic household tools. Clear instructions are included.

If you choose to place the sauna outdoors, it must be fully protected from rain, moisture, and direct weather exposure. For best long‑term performance, indoor installation in a well‑ventilated area is recommended.

Maintenance is simple: we recommend using a clean towel during each session to absorb sweat and protect the timber. After use, allow the sauna to air out with the door open for a few minutes. Occasional cleaning of the interior wood with a mild, natural cleaner helps keep the cabin feeling fresh. There’s no steam or water system to manage, which makes long‑term care easier than with traditional saunas.

Most people find that 30-45 minute sessions provide excellent results without overwhelming the body. Because infrared works at comfortable temperatures, many users enjoy sessions multiple times per week.

In addition to the sauna itself, you’ll receive a bonus pack that may include items like a backrest, towel and cup holders, an aromatherapy unit, and a dry brush. These enhance your comfort and help you build a richer home wellness routine.

Sun Stream offers responsive customer support for installation questions, maintenance tips, or any part replacements you might need over the years. Our team is here to help ensure your sauna continues to deliver great results.
