Description

What are Harvia AC3000 sauna stones?

Harvia AC3000 are angular split-face sauna stones of dark grey olivine diabase, 2–4" (5–10 cm) across, sold in 44 lb (20 kg) boxes. They are the size and type of stone Harvia's manuals specify for the KIP, The Wall, Vega Compact, Virta and Virta Combi 6–9 kW, Club and Cilindro Half electric heaters. They come from Finland.

Which Harvia heaters take AC3000 stones?

These Harvia electric heaters take AC3000, in the amounts below. Each box holds 44 lb (20 kg), and the box counts cover each load.

Stone load per Harvia's heater manuals; the Club's from the stone chart, as its manual gives none
Stone load Boxes of AC3000
Harvia KIP 4.5, 6 and 8 kW 44 lb (20 kg) 1
Harvia The Wall 6 and 8 kW 44 lb (20 kg) 1
Harvia Vega Compact 1900 and 3500 About 29 lb (13 kg) 1
Harvia Virta 6 kW, 8 kW and 9 kW 110 lb (50 kg) 3
Harvia Virta Combi 8 kW and 9 kW 110 lb (50 kg) 3
Harvia Club 10, 12.5 and 15 kW 132 lb (60 kg) 3
Harvia Cilindro Half 6, 8 and 9 kW (external control or built-in controls) 200 lb (90 kg) 5
Harvia Cilindro Half 10.5 kW 264 lb (120 kg) 6

Which Harvia heaters need a different stone?

The Harvia Spirit needs rounded stones: its manual does not allow split-face stones, so it takes Harvia R-991 instead. Harvia's wood-burning stove manuals call for larger 4–6" (10–15 cm) stones, the Harvia AC3020. For any other Harvia heater, the heater's manual gives the stone size and amount.

A $60 shipping fee per box applies unless the stones are ordered and shipped together with a sauna heater or stove.

What Topture Customers Say

Topture is rated 4.9/5 across 462 customer reviews

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 buyer

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..

I had no idea what I was missing!

My sauna heater is really, really old, but it still works so I still use it. That said, the rocks were also really old. These new stones look so much better and seem to even hold the heat better as well. Like I said in the title, I had no idea what I was missing! Puts a lot of new life into an old, Montgomery Ward heater.

We're always striving to enhance the sauna experience for our customers, and it's great to know that the stones have added new life to your heater. Thank you for choosing Topture. Enjoy your sauna!

Frequently Asked Questions

General Topture Questions

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

Topture is an online retailer serving customers in the contiguous United States. The company is Topture LLC, a Wyoming limited liability company, and its registered business address is 30 N Gould St, Ste N, Sheridan, WY 82801.

Orders ship from manufacturer and distributor warehouses in the U.S. and Canada, and some products ship directly from the manufacturer in Europe. Each product page shows its estimated delivery time.

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. Products purchased through Topture include the applicable manufacturer’s warranty, subject to the manufacturer’s terms. You’ll find the warranty details for each product under the "Warranty" tab on its product page, and we help with troubleshooting and warranty coordination if an issue comes up.

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.
