Frequently Asked Questions
Product Fit and Comparison
How does the CL4G compare to a barrel sauna of the same size?
More headroom (74.8" vs ~62" interior height in a typical barrel), better airflow circulation, and a flat floor that's easier to walk on. Heats up faster because the cube shape distributes warmth more evenly than a curved barrel wall.
Is the CL4G the same sauna as the Finsauna Solara 200GF?
Yes. Same factory, same kit, rebranded for different distribution channels. Buy based on the dealer relationship and after-sale support, not the brand label.
CL4G vs SISU Charlie — which is better?
The CL4G uses Thermo-Spruce (heat-treated for rot resistance) and includes the Wi-Fi LED light bar and contoured Thermo-Aspen bench in the base kit. The SISU Charlie uses Western Red Cedar. Cedar smells better when new; Thermo-Spruce lasts longer in wet climates.
Does the CL4G actually fit three people?
Three adults can sit upright for shorter sessions. Two adults are comfortable for 20+ minute sessions with room to recline. If you want true 3-person comfort, look at the CL5G 4-person cube (55.1" interior depth vs 41.3" on the CL4G).
Is Thermo-Spruce better than cedar for outdoor saunas?
For longevity in wet or coastal climates, yes. Thermo-Spruce is kiln-treated at high heat to drive out moisture and resist decay. Cedar has better natural aroma but degrades faster in heavy rainfall or freeze-thaw cycles unless it's regularly sealed.
Use, Install, and Maintenance
How long does the CL4G take to heat up?
About 45 minutes to reach 180-190°F with a 6kW heater in mild weather. Add 15-20 minutes in winter conditions below freezing. Most owners set a timer or use a smart plug.
How hard is the assembly?
DIY-friendly for two people with basic carpentry tools. About 10-12 hours over a weekend. The kit ships pre-cut with labeled panels and hardware. Roof shingling is the most time-consuming step.
What maintenance does the Thermo-Spruce need?
Wipe down benches after each use. Deep clean the interior monthly with a sauna wood cleaner. Treat the exterior annually with odorless sauna wood oil or protective sauna wax. Inspect drip rails and roof shingles twice a year.
Does the CL4G come with a heater?
No. The heater, stones, and control unit are sold separately. This lets you choose between Harvia, HUUM, or other brands based on preference. Most CL4G buyers pair it with a 6kW Harvia heater.
Can the CL4G be installed indoors?
It's engineered for outdoor use with a weatherproof roof, but it can be placed in a garage, basement, or covered patio if ventilation is adequate and you have proper clearance from combustibles around the heater.
How is the CL4G shipped and what should I inspect on delivery?
Curbside freight delivery, typically 2-3 weeks from order. Freight is charged as a separate line item at checkout. Inspect the crate for visible damage before signing the freight bill. Note any damage on the delivery paperwork before the driver leaves and call 866-861-6317 within 24 hours.
