Description

A Work of Art That Delivers Perfect Steam

Inspired by the purest element in nature—a drop of water—the HUUM DROP is for the sauna owner who believes that a heater should be as beautiful as it is powerful. This Red Dot award-winning, wall-mounted heater transforms the angular interior of a classic sauna into an elegant and sophisticated space.

But the DROP isn't just about looks. Its brilliant design holds up to 121 lbs of sauna stones, far exceeding most standard heaters. This massive stone capacity is the secret to a soft, gentle, and long-lasting steam, or löyly, that creates a truly world-class sauna experience every single time.

✔️ Award-Winning "Water Drop" Design
✔️ Superior, Long-Lasting Steam
✔️ Smart Control with WiFi App

Perfect For...

The design-conscious sauna owner who wants a stunning centerpiece for their small to mid-sized sauna. It’s the ideal choice for anyone who values both a superior steam experience and a clean, minimalist aesthetic.

The Ultimate Convenience: Control from Anywhere

The HUUM DROP is designed to work seamlessly with the sleek UKU control system, allowing you to operate your sauna from an elegant wall-mounted panel or, for the ultimate in modern luxury, from the HUUM mobile app on your phone. Imagine leaving work and tapping a button to preheat your sauna, so it’s perfectly hot the moment you walk in the door. That's the convenience the DROP provides.

Topture is rated 4.9/5 by 461+ verified customers

We thought about buying a sauna for years and finally did. We absolutely love it, especially in the winter. It’s incredibly easy to assemble with two people the whole family uses it.

Verified owner

Ordered this sauna fall 2024 and we love it. No better feeling during a Minnesota winter. Lastly, I have to mention the customer service for this purchase has been like no other. Any questions or requests I had were addressed immediately by Topture. I got more than I expected from them and have already recommended them to several people looking for saunas. SO if you're thinking about it, JUST DO IT already..

Thanks for the great service - greatly appreciated.

WHY BUY FROM TOPTURE?

The sauna may be the same. The buying experience isn't.

Buying a sauna involves more than choosing a model and clicking checkout. Heater sizing, electrical requirements, freight delivery, installation, and warranty support all matter.

Before you buy elsewhere

Will they help you compare alternatives, or only answer questions about the product you've already selected?

Verify that the retailer is authorized for the brand and that your manufacturer warranty will be valid.
Freight delivery
We help coordinate heavy-freight delivery and provide guidance on receiving and inspecting your shipment.

Showpiece performance with everyday convenience
Ordered the HUUM Drop for our 7x7 cedar sauna and it’s been fantastic. Delivery was quick and everything arrived spotless. The wall mount was straightforward. I had an electrician handle the 240V hookup. With the UKU controller and app, I preheat on my way home and it’s ready when I arrive. The big stone bed gives smooth, consistent steam without harsh bursts. So glad I chose this one.

Love hearing that you use the UKU controller to preheat you sauna heater on the way home. Thanks for shopping with us and enjoy those effortless sessions!

Elegant heater, smooth delivery
Arrived fast and well-packed; not a scratch. Mounting to the wall was straightforward, and it cleaned up the floor space in our small cedar room. Highly recommend.

Thanks so much for the kind words! Love hearing the Elegant Heater opened up your floor space and was a breeze to mount. We really appreciate the recommendation.

Soft steam and beautiful design
Upgraded to the 9 kW for a taller ceiling. Once warmed, the thick stone bed gives silky steam without spikes. I had it put on a 50A circuit.

Love hearing that the HUUM Drop Sauna Heater is giving you that silky, even steam. Smart move going 9 kW for the taller room, the stone mass really shines once it’s warmed up. Enjoy!

Elegant Design, Gentle Steam, Worth Every Penny
We installed the HUUM Drop 7.5kW in our small home sauna about a month ago and couldn’t be happier. The first thing everyone notices is how beautiful it looks, it almost feels like a sculpture on the wall. Setup was simple for our electrician, and once connected to the UKU WiFi control, it’s been effortless to use. I love being able to preheat the sauna from my phone before getting home. The steam quality is noticeably smoother compared to our old heater, and the temperature stays consistent throughout the session. It also heats up faster than I expected for the size. If you’re looking for both style and real performance, this is it. Would absolutely buy again.

Thank you for the glowing review! Hearing that the steam feels smoother and the heat stays consistent is exactly the experience we aim for with the HUUM Drop Sauna Heater. We’re thrilled it also adds a beautiful touch to your space, enjoy many relaxing sessions ahead!

Solid build, easy professional install
Had an electrician wire the 7.5 kW on a 40A breaker; mounting bracket made placement simple. Looks fantastic.

Love hearing the install was a breeze. Thanks for shopping the HUUM Drop Sauna Heater with us, and enjoy the many sessions to come!

Remote preheat is a game changer
Went with the 6 kW for a 7x7 room. Would buy again.

Love hearing that remote preheat is changing the game for you. Nothing beats stepping into a ready-to-go space. Thanks for choosing the HUUM Drop sauna heater and for the vote of confidence!

Frequently Asked Questions

General

Where are you located, and where do you ship from?

We are a U.S.-operated company with our main headquarters in Sheridan, Wyoming.

Orders are shipped across the continental U.S. from our network of warehouses, managed by our logistics partners in California, Illinois, Texas, New York, Florida, and Toronto.

How much is shipping?

Orders over $200 ship free within the continental United States. Orders under $200 carry a small shipping fee.

Two exceptions: SaunaLife and ThermaSol products carry a freight charge at any order value, and sauna stones ordered without a heater ship at $60 per box because of their weight.

Every charge is shown at checkout before you pay.

Do you provide financing?

Absolutely! To view your financing offer, simply select Shop Pay Installments as your payment method at Step 3 of checkout.

You'll need to enter a debit card to receive your offer, but don’t worry—you can still back out before completing the purchase.

How long will it take for my items to arrive?

If your order is in stock, most orders ship within 2–7 business days of purchase. Transit time then depends on the distance from the warehouse and, for freight, on booking a delivery appointment.

For custom, pre-order or made-to-order items, the estimated delivery time frame is listed on the product page. Delivery dates are estimates, so please don't book installation labor until your order has arrived and been inspected.

What happens after I place my order?

As soon as you place your order, you'll receive a confirmation email with your order details—be sure to keep it for your records. Once your order ships, you'll receive another email with tracking information.

For freight deliveries, the carrier will call or text you to schedule an appointment once the shipment reaches their local terminal. Someone needs to be there to inspect the shipment and sign for it. Smaller parcels arrive by UPS or FedEx without an appointment.

Is there a warranty?

Yes, all products come with a manufacturer warranty. You can find the specific warranty details for each product under the "Warranty" tab on its product page.

Do you have a showroom?

We don’t have a showroom — we sell online. Our team is available by phone, email and chat to help you compare models, sizes and heaters, and we can send dimensions, installation manuals and electrical requirements before you buy.

Where do you deliver to?

We deliver throughout the 48 contiguous states, with curbside freight delivery for large items. Free shipping and standard rates apply there only. Alaska, Hawaii, Puerto Rico, other U.S. islands and Canada are quoted separately, depending on the brand and model. We can't ship freight or oversized items to P.O. boxes.

Do you ship internationally?

International Shipping

For many products, yes, including to Canada, by custom quote. Email contact@topture.com with the product and your address before you order; availability and cost depend on the brand and model. Any duties, taxes and customs fees are your responsibility.

Shipping to Hawaii, Alaska, and Puerto Rico

Free shipping applies to the continental United States only. Shipping to Alaska, Hawaii, Puerto Rico and other U.S. islands is quoted separately and depends on the brand and model. Email contact@topture.com for a quote before you order.
