Description

Harvia Pro 20 SL Wood-Burning Sauna Stove with Exterior Feed - The Ultimate Two-in-One Sauna Experience

Enhance your sauna experience with the versatile Harvia Pro 20 SL. This unique stove lets you heat your sauna from an adjoining room or even from outside, making it an ideal solution for those who value both functionality and ambiance. While one person enjoys the warmth and steam in the sauna, another can relax by the fire in the adjacent room, admiring the glow through the cast-iron-framed glass door.

Product Highlights:

  • Dual-Room Heating Solution: The Harvia 20 SL serves as both a sauna stove and a fireplace, heating two spaces at once. It’s perfect for small to medium-sized saunas, efficiently heating areas from 283 to 706 cubic feet.
  • Convenient Exterior Feed: With its exterior feed capability, the stove allows you to add wood from outside the sauna room, preserving the ambiance and convenience. The reversible door also lets you customize the setup to fit your space.
  • High-Performance Design: The 24kW stove features a large stone compartment that creates generous, soothing steam. With a capacity of 88 pounds of stones (2 boxes, sold separately), this stove ensures long-lasting warmth and a luxurious sauna experience.
  • Durable and Stylish: Crafted in Finland with high-quality materials, the Harvia Pro 20 SL is built to last. The cast-iron-framed glass door provides a clear view of the fire, enhancing the sauna’s ambiance. Adjustable feet ensure stable installation, and the stove pipe connections are conveniently placed on top and upper rear for flexible setup.

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..

Verified owner

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

Choosing the right sauna
Compare models across leading sauna brands based on your space, climate, capacity, preferences, and budget.
Will they help you compare alternatives, or only answer questions about the product you've already selected?

Ask who will check that the heater and controls are right for your installation before you order.
Authorized products
Products are sourced through authorized channels and include the applicable manufacturer warranty.View independent listings
Verify that the retailer is authorized for the brand and that your manufacturer warranty will be valid.
Freight delivery

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.
