HUUM
Minimalist Estonian Design
The Art of Essential Heat
Born in Estonia, HUUM creates sauna heaters that embody the Nordic philosophy of less is more. Each heater is a sculptural masterpiece that delivers authentic löyly while transforming your sauna into a work of art.
Estonian Innovation
Founded in Estonia's capital Tallinn, HUUM emerged from a simple question: why do sauna heaters have to be ugly? The answer was a revolutionary approach that married engineering excellence with Scandinavian design sensibility.
Form Meets Function
Every HUUM heater is designed to maximize stone capacity while minimizing visual footprint. The iconic DROP model holds 120 kg of stones in a form that seems to defy physics—a teardrop of pure heat waiting to be released.
Essential Experience
HUUM believes the heater should disappear into the experience. No complex controls, no visual clutter—just stone, steam, and the ancient ritual of sauna. Smart controls are hidden in elegant simplicity.
"The HUUM experience isn't just about heat—it's about the pursuit of perfection in every detail."
Why Choose HUUM
Massive Stone Capacity
Up to 120kg of stones for authentic, long-lasting löyly that traditional saunas are known for.
Award-Winning Design
Multiple international design awards for heaters that transform your sauna into a gallery.
Smart Integration
Optional WiFi control with the UKU controller—adjust your sauna from anywhere with a smartphone.

All delivery times are estimates and may extend due to carrier delays or unforeseen circumstances. Backordered items ship when available — we confirm your ETA at time of order. Tracking is emailed as soon as your order ships.
How Freight Delivery Works
Large items (saunas, cold plunges, hot tubs) ship via LTL freight. Smaller items (heaters, accessories, wellness devices, Lumaflex, red light towers) ship via UPS, FedEx, or USPS.
1. We ship your order. Tracking is emailed to you with the estimated delivery timeline.
2. The carrier calls you. The freight company calls to schedule your delivery appointment. You pick the date and time window.
3. Curbside delivery. Delivery is to the curb via semi-truck with liftgate (when available). You'll need a plan to move it from the curb to its final location.
4. Sign and inspect. You must be present to sign. Inspect for damage before signing — note any issues on the delivery receipt.
Unloading Your Sauna
The driver delivers to the curb only. You are responsible for moving the product to its final location. Have equipment and help arranged before delivery day.
Rent a forklift — Most common choice. Requires forklift extensions. ~$150–300/day.
Hire a tilt tow truck — Flatbed tow with tilt/slide functionality. ~$200–400.
Hire a rigging/moving crew — Professional movers with equipment. Get quotes in advance.
Tilt tow service (Dundalk only) — Available for $750. Contact us to add to your order.
Clearlight saunas ship in flat panels, not pre-assembled crates. Most can be carried inside by two people without heavy equipment. Dundalk saunas ship in crates exceeding 92" and 800–1,600 lbs — liftgate service is not available for these shipments.
Damage Claims
If your order arrives damaged, we'll get you a replacement as quickly as possible.
1. Inspect packaging for visible damage before signing.
2. Note damage on the delivery receipt — write "damaged" and have the driver sign.
3. Take photos of packaging and product damage.
4. Email photos to info@thesaunarepublic.com with your order number within 24 hours.
5. We file the claim and ship your replacement.
Damage must be reported within 24 hours of delivery with photos. Claims filed after 24 hours may not be eligible for a free replacement. Always note visible damage on the delivery receipt — even if it seems minor.
Carriers & Address Info
We reserve the right to select the carrier for all shipments.
Small items (heaters, accessories, wellness devices, red light towers) — UPS or FedEx
Large items (saunas, cold plunges, hot tubs) — LTL freight carriers
Lumaflex devices — UPS, FedEx, or USPS
Once large items ship, we cannot change addresses or schedule specific delivery dates. If an item is returned due to an incorrect address, you're responsible for shipping costs both ways. If freight delivery fails because the carrier couldn't access your property, it's treated as a return per our return policy.
