Description

Introducing the HUUM HIVE Flow LS Sauna Stove, an innovative and eco-friendly solution for sauna rooms between 282 and 635 cubic feet. With its patent-pending design, the Flow LS maximizes efficiency by directing 75% of the heat from the firewood directly into your sauna, minimizing heat loss through the chimney. This not only reduces firewood usage, making it highly economical, but also supports a more sustainable, environmentally-friendly experience.

The Flow LS features an extended firebox that can be installed through a wall, allowing you to load firewood from an adjacent room, keeping your sauna clean and free of debris. Additionally, the firebox doubles as a fireplace for the next room, offering warmth and a cozy atmosphere. Whether you want to use longer firewood or maintain a cleaner sauna, the HUUM HIVE Flow LS is the perfect blend of efficiency, sustainability, and convenience.

    Requires sauna stones (10 boxes of 2-4" stones) sold separately.

      Rated 5/5 based on 122 happy owners

      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..

      Verified owner

      Thanks for the great service - greatly appreciated.

      What sauna owners are saying

      STILL UNSURE?

      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?

      We’re proud to offer FREE SHIPPING on all orders over $200 within the Continental United States.

      The only exception is sauna stones—due to their weight and high shipping costs, we apply a shipping charge when they are purchased without a heater.

      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 you order today, you can expect delivery within 5-13 business days. In-stock products typically ship within 2-6 business days, and once they leave the warehouse, transit time is usually 3-7 business days, depending on your location. Let us know if you need more details!

      For pre-order or made-to-order items, the estimated delivery time frame is listed on the product page.

      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 we process your order, we'll begin preparing it for shipment. As soon as it ships, you'll receive another email with tracking information.

      1-2 days before delivery, the delivery team will call you to schedule an appointment. You’ll need to be home to accept and sign for the delivery at the scheduled time.

      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, which means we can bring you the lowest prices as we don’t need to worry about any extra costs!

      Where do you deliver to?

      We offer free Curbside Delivery to all 48 lower states and for some products even Canada.

      Do you ship internationally?

      International Shipping

      Yes, we offer international shipping for many of our products. Customers outside the US can request a personalized shipping quote by contacting us. Please be aware that any applicable taxes or customs fees will be the responsibility of the customer. Note that some items may be subject to shipping restrictions.

      Shipping to Hawaii, Alaska, and Puerto Rico

      We ship to Hawaii, Alaska, and Puerto Rico, although most items are subject to additional shipping fees. To obtain specific rates and prevent any restocking fees, please email us at contact@topture.com.
