The CL3G is designed for homeowners looking for a streamlined, high-efficiency personal sauna experience. Because of its smaller interior volume, it heats up rapidly and offers lower ongoing operating costs.
Footprint: Fits easily on existing patios, small decks, or compact backyard spaces.
Usage: Ideal for solo daily recovery, post-workout routines, or couples.
Heater Pairing: Commonly paired with 4.5 kW heaters (such as the Harvia KIP45B or HUUM DROP 4.5 kW).
The CL5G delivers a full cabin feel, giving you room to stretch out or host family and guests comfortably. It functions as a bold aesthetic centerpiece for dedicated outdoor living areas.
Footprint: Requires a larger, level pad (concrete, paver, or reinforced deck).
Usage: Built for multi-person sessions, family wellness, and entertaining.
Heater Pairing: Requires higher-output units (such as 6.0 kW to 7.5 kW heaters) to maintain consistent cabin heat.
Backyard Space & Site Prep: Measure your space accurately and ensure at least 12–18 inches of clearance around the cabin for maintenance access and air ventilation. Both units require a flat, level foundation (concrete pad, prepared paver base, or structural deck).
Electrical Setup: Both models require dedicated hardwired power configured by a licensed electrician. Electrical costs depend on your home panel's available capacity and the distance from the breaker panel to your sauna site.
Daily Routine vs. Social Use: If your main goal is daily contrast therapy or personal recovery, the CL3G provides maximum efficiency. If you plan to host sessions with friends or family, the additional bench space in the CL5G prevents overcrowding.
