About The Origin Outdoor Saunas

The Origin Series is how most people end up getting an outdoor sauna. It’s not a kit you assemble yourself and it’s not a $30,000+ custom project with a six-month timeline. We build the entire sauna in our shop — framing, insulation, paneling, benches, heater, roof, floor, and deliver it finished on a shed hauler. Your electrician wires the heater, you download the app, and you’re taking steam.

The series comes in three sizes: the 5×7 (our most popular outdoor footprint), the 6.5×8 (the one most families settle on), and the 8×8 (built for groups of 4-6). Each size is available in four bench layouts, and you can customize from there — interior wood species, porch, siding style, windows, lighting. Start with the base and add what you want.

Every Origin sauna ships with the same core build: authentic Nordic White Spruce walls and ceiling, Canadian Hemlock benches, an 8kW Finnleo Designer SL2 heater with Wi-Fi control, LED backrest lighting, double-paned windows, and a steel metal roof. Same materials and construction across all three sizes.

Key Features & Benefits

These saunas are built to handle Minnesota winters and deliver real heat. Here’s what’s actually in the box.

Grade-A Nordic White Spruce Interior

Sourced from trees grown north of 60 degrees latitude in Finland, near the Arctic Circle — about 80 years of slow growth produces tight grain with only small, living knots.

Unlike cheaper whitewood, this spruce doesn’t absorb sweat, which keeps the interior smelling clean session after session. When heated, it gives off a subtle Scandinavian forest scent.

8kW Finnleo Designer SL2 Heater

A workhorse-style heater with a compact footprint and fast, efficient heating. The SL2 is Finnleo’s go-to residential heater — clean lines, durable construction, and enough power to bring all three Origin sizes to full temperature.

SaunaLogic 2 Wi-Fi Control

Start your sauna from your phone so it’s ready when you get home. The SaunaLogic 2 connects to your Wi-Fi and lets you set temperature, timer, and lighting from the app. No walking out to the backyard in your socks to preheat.

R-13 Insulation with 2x4 Framing

Full wall-cavity insulation, not the thin foam sheeting you see in some outdoor kits. R-13 holds heat in and keeps operating costs down — especially during a Minnesota January when it’s -10 outside.

Origin 5x7

Our most popular outdoor size. Compact enough for smaller backyards, big enough for a proper session.

  • Interior: 60″ D x 84″ W x 84″ H
  • Exterior: 67″ D x 91″ W x 102″ H
  • Roof: 91″ x 107″
  • Seats: 3 (Classic) to 4 (L-Bench or Lounge)
  • Base price: $20,000

Origin 6.5x8

About 11 inches of added depth over the 5×7. This is the size most families land on — noticeably more bench space without a much bigger footprint.

  • Interior: 71″ D x 89″ W x 84″ H
  • Exterior: 78″ D x 96″ W x 105″ H
  • Roof: 102″ x 112″
  • Seats: 3-4 (Classic) to 4-5 (L-Bench or Lounge)
  • Base price: $21,500

Origin 8x8

Built for groups. A full 89″ x 89″ inside gives the L-Bench and Lounge layouts room to really open up. If you regularly sauna with family or friends, this is the one.

  • Interior: 89″ D x 89″ W x 84″ H
  • Exterior: 96″ D x 96″ W x 105″ H
  • Roof: 120″ x 112″
  • Seats: 4-5 (Classic) to 5-6 (L-Bench or Lounge)
  • Base price: $23,500

Four bench layouts

Every Origin model is available in four bench configurations. The upper bench is where you sit — the lower bench is your step and footrest.

Classic — Stadium-style with a 24″ upper bench along the back wall and a lower step. Straightforward, traditional. Included at base price.

L-Left — The upper bench wraps from the back wall down the left side, giving you more seating on the upper tier. Choose based on where you want the door relative to the bench. Base price + $250.

L-Right — Mirror of the L-Left. Same dimensions, same capacity. Pick whichever orientation works for your space and door placement. Base price + $250.

Lounge — Heater centered on the back wall with two upper benches facing each other. More of a social, face-to-face setup. The 8×8 Lounge is the most comfortable version — plenty of legroom on both sides. Base price + $500.

Interior Wood Upgrades

Nordic White Spruce comes standard. If you want a different look or feel, four interior wood upgrades are available at the same price across all three sizes:

  • Knotty Cedar — +$950. Rustic cedar character at a lower price point than clear.
  • Clear Canadian Hemlock — +$2,400. Neutral tone, hypoallergenic, even heat radiation.
  • Clear Western Red Cedar — +$3,400. The classic sauna wood — aromatic, naturally resistant to bacteria and decay.
  • Black Taika — +$6,000. Contemporary dark finish for a modern look.

How it Works

Choose Your Sauna

Pick your model, bench layout, exterior color, and any upgrades.

Prepare Your Site

While we build, you prep two things:

  • Foundation — A flat, level pad. Three options:
    • Compacted gravel — 8-10″ of Class 5, compacted in lifts (most popular)
    • Concrete slab — 4″ on a gravel base (most permanent)
    • Patio pavers — on compacted gravel with leveling sand
    • Pad should extend 4-12″ beyond the sauna footprint on all sides.
  • Electrical — 240V dedicated circuit (40A for 8kW heaters, 50A for 9kW). Hire a licensed electrician — we can recommend one. Plan the electrical run before the sauna arrives.

 

We Build It

We build your entire sauna in our shop — framing, insulation, paneling, siding, benches, heater, controls, roof, and floor.

Delivery

  • Your finished sauna arrives on a shed hauler and is placed directly on your prepared pad. You’ll need a flat, clear path from the street to the final spot — wide enough for the sauna to pass through. We’ll discuss site access during your consultation.
  • Free delivery within 75 miles of Cokato. $4.50/mile beyond.

 

Connect and Sauna

Your electrician wires the heater. Download the SaunaLogic app, connect to Wi-Fi, and take your first session.

Lead time: Typically 5-8 weeks from order to delivery.

SaunaLogic 2 Wi-Fi Control - Total Control, Anytime, Anywhere

The Finnleo Designer SL2 comes with the SaunaLogic2 Control—a sleek, modern touchscreen that puts your sauna settings right at your fingertips. And the best part? It’s Wi-Fi enabled, so you can control your sauna from anywhere using your smartphone or tablet.

Common Questions

Here are some of the most common questions people ask.
The largest model (8×8) has a 96″ x 96″ exterior footprint — that’s 8 feet by 8 feet. Add 4-12 inches on each side for the pad, and you’re looking at roughly a 9′ x 9′ area. The 5×7 only needs about a 6′ x 8′ pad. You’ll also need a clear path from the street wide enough for the sauna to pass through on delivery day.

Three options: compacted Class 5 gravel (8-10 inches deep, most popular), a 4-inch concrete slab on gravel (most permanent), or patio pavers on compacted gravel with leveling sand. The pad should extend 4-12 inches beyond the sauna footprint on all sides. Most people go with gravel — it drains well and costs less than concrete.
A 240V dedicated circuit with 40-amp service for the 8kW heater. You’ll need a licensed electrician to run the wiring from your panel to the sauna location. Plan the electrical run before the sauna arrives so your electrician can wire it the day of delivery or shortly after. We can recommend electricians in the area if you need one.

Typically 6-8 weeks. We build the sauna in our shop while you prepare your site (pad and electrical). Once it’s delivered and your electrician connects the heater, you’re ready to go.

An 8kW heater running for an hour uses about 8 kWh of electricity. At $0.10/kWh (Minnesota average), that’s roughly $0.80 per session. If you sauna four times a week, expect $15-$30/month depending on session length and outdoor temperature.
