Description

For those who refuse to compromise, welcome to the pinnacle of home wellness. The Finnmark Trinity XL is the largest and most powerful sauna in the lineup, a true 3-in-1 sanctuary designed for the ultimate sauna experience. It combines three distinct experiences into one magnificent cabin: deep-penetrating infrared, high-heat traditional steam, and red light therapy.

Powered by a robust 4.5kW Harvia traditional heater and an advanced infrared system, the Trinity XL is engineered for unparalleled performance. This is the definitive sauna experience, offering unmatched space, power, and versatility for you, your family, and your friends.

Three Experiences, Unmatched Power

The Trinity XL allows you to tailor your session to your exact needs, offering three distinct experiences in one spacious cabin.

  • For Deep, Penetrating Warmth (Infrared): Immerse yourself in a room filled with deep, penetrating warmth from the UL-listed Spectrum Plus™ infrared heaters. This is a dry heat (up to 170°F) for a deep, relaxing sweat.
  • For an Authentic Finnish Experience (Traditional): Engage the legendary 4.5kW Harvia KIP traditional heater. Ladle water over 50lbs of hot stones to generate powerful waves of invigorating steam, or "löyly." This is the classic, high-heat (up to 194°F) experience for a truly intense sweat.
  • For a Calming Finish (Red Light): Bathe in the warm glow of the Spectrum Red Light™ Therapy panel and its 650nm red light, a calming way to end any session.
Pro-Grade Electrical Requirements

To deliver its exceptional performance, the Trinity XL requires a professional power setup. Here’s what you need to know:

  • Outlet Needed: This high-performance sauna requires a dedicated 240V, 20A circuit. This is essential for powering both the 4.5kW traditional heater and the advanced infrared system safely and effectively.
  • Why 240V?: Like other professional-grade appliances, this voltage is necessary to heat the large cabin quickly and maintain consistently high temperatures for the best results.
  • Installation: A licensed electrician will need to run the proper wiring and install the correct outlet for the sauna.
Premium Features & Construction
  • Antimicrobial Canadian Cedar Interior: The beautiful cedar interior naturally resists mold and bacteria, keeping your sanctuary fresh while providing that classic sauna aroma.
  • Durable Thermal-Treated Exterior: The Thermal Plus™ Aspen exterior is chemically-free and treated to resist warping, rot, or chipping for decades of durability.
  • Intuitive Controls & Premium Sound: A sleek, built-in LCD touchscreen with Bluetooth lets you control your entire experience, while 6" HiFi marine-grade speakers deliver crystal-clear audio.
  • Expansive Two-Tier Bench System: The extra-large, multi-level bench provides ample room for 4-5 people and allows you to sit higher to enjoy the most intense heat.

Why Finnmark?

Shopping for an infrared sauna can feel overwhelming. We get it.

Let's be honest, you can spend hours scrolling through websites and still be left wondering which sauna is actually right for you. It's easy to get lost in a sea of technical jargon and competing claims.

That’s why we put this guide together. Below are the core reasons Finnmark stands apart, not just in quality, but in the results and peace of mind you get. Here’s what makes the difference.

The Finnmark Difference: 7 Core Principles

Instead of a long, confusing list, it really boils down to these key commitments.

  1. Higher Heat (Up to 170°F). This is a big one. While many brands top out around 145°F, Finnmark saunas are engineered to reach a powerful 170°F for a deeper, more intense sauna session.
  2. Advanced Full-Spectrum Heating. Finnmark is one of the only brands that combines long-wave Carbon and high-output Ceramic heaters. Think of it as getting two types of heat at once: deep, penetrating infrared warmth while the surrounding heat provides a gentle, 360-degree immersion. No cold spots, just total-body warmth.
  3. Ultra-Low EMF Radiation (All 4 Types). You're using a sauna as part of your wellness routine, so it should be a clean experience. Finnmark saunas feature low-emitting heaters and upgraded, shielded electrical components to minimize all four types of radiation (EMF, ELF, EMI, and RF) for the lowest possible exposure.
  4. Premium, Non-Toxic Materials. The interior is beautiful, antimicrobial Canadian Cedar that resists mold and won't off-gas chemicals. The power supplies and internal wiring are all upgraded to last 12-15 years, not the typical 5-7, ensuring your sauna is a lasting investment.
  5. A Warranty You Can Actually Trust. Finnmark provides a 10-year warranty on the sauna, and its Spectrum Plus™ heaters carry a lifetime warranty. See the warranty terms for complete coverage and exclusions.
  6. Certified Safe and Ethically Sourced. With more third-party safety certifications (ETL, CE, UL) than nearly any other brand, you can relax with peace of mind. The wood is also sourced from a Forest Stewardship Council (FSC) approved mill, ensuring it's harvested responsibly.
  7. Decades of Manufacturing Experience. These saunas are built in a dedicated sauna factory—not a generic furniture factory. That means every unit is crafted by experts with decades of specialized experience.

What Customers Are Saying

You don't have to take our word for it. Here's what people who use their Finnmark sauna every day have to say.

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.

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.
