Description

The HUUM Drop 4.5 redefines sauna elegance through its water-drop silhouette—a design that earned the Red Dot Award for seamlessly blending sculptural beauty with functional engineering. This wall-mounted heater stands apart with an impressive 122-pound rock capacity, enabling deeper water-to-stone interaction for richer steam and more intense heat distribution. The generous stone mass ensures consistent, enveloping warmth that transforms each session into a premium bathing ritual. Optional Wi-Fi connectivity grants you complete control from anywhere, allowing preheating before you arrive. Built for discerning bathers who refuse to compromise on performance or aesthetics, the Drop 4.5 delivers both in equal measure.
