Brand Overview

HUUM is a modern disruptor in the sauna industry. Known for their minimalist, award-winning designs, they use open rock baskets to create soft, humid steam and a stylish focal point in any sauna.

Harvia, founded in 1950, is a Finnish institution. They’ve been making sauna heaters for generations, and their products are trusted by both homeowners and commercial spa operators worldwide.

Design & Aesthetics

HUUM heaters — like the DROP and CLIFF — are as much art as they are appliances. Their open, rounded designs display the stones beautifully while blending into modern interiors.

Harvia offers a variety of looks, from traditional metal casings to more contemporary models like the Cilindro and The Wall, which bring modern flair without losing that classic sauna feel.

Verdict: Choose HUUM if you want your heater to be a design centerpiece. Choose Harvia if you prefer a balanced look that works in any setting.

Heat Performance

HUUM heaters can hold a massive amount of stones — sometimes over 200 pounds — which results in long-lasting, soft, and enveloping heat. The open basket allows more water contact with the stones, creating a rich löyly.

Harvia focuses on fast heat-up times and precise temperature control. While many Harvia models have smaller stone capacities, their efficient elements and insulation ensure consistent performance.

Verdict: HUUM is best for soft, humid heat that lasts. Harvia is perfect if you want quick heating and precision control.

Controls & Technology

HUUM pairs many of its heaters with the UKU control system, available in both local and WiFi-enabled versions. With the WiFi option, you can start your sauna from your phone — perfect for busy schedules.

Harvia offers a broad range of controls, from basic mechanical dials to advanced digital systems like the Xenio. While some models support remote start, Harvia focuses on simple, dependable operation.

Verdict: HUUM wins for sleek, app-based control. Harvia offers more choice for every budget.

Durability & Build Quality

HUUM heaters are handcrafted in Estonia using stainless steel and high-grade components. The open design requires more frequent stone maintenance but delivers unmatched steam quality.

Harvia heaters are built in Finland and have a long track record of lasting 15–20 years with basic care. Their enclosed designs protect the stones and heating elements for reduced maintenance.

Verdict: Both are durable, but HUUM offers premium craftsmanship, while Harvia boasts time-tested endurance.

Pricing & Value

HUUM heaters typically sit in the mid-to-high price range, reflecting their design and large stone capacity.

Harvia offers something for everyone — from affordable entry-level models under $1,000 to high-end commercial units over $5,000.

Pros & Cons

HUUM Pros: Stunning modern design, large stone capacity, soft steam, WiFi controls.
HUUM Cons: Higher price point, more frequent stone maintenance.

Harvia Pros: Proven reliability, wide model range, fast heating, easy maintenance.
Harvia Cons: Smaller stone capacity on many models, less design flair on entry-level units.
