Description

The SaunaLife CL4G is a 3-person outdoor cube sauna kit handcrafted in Northern Europe. Its full-length panoramic bronze glass front sets it apart from every barrel and cabin sauna in this price range — natural light fills the interior, and you get a clear view of your backyard while you sweat. Inside, the contoured knotless Thermo-Aspen bench and arched backrest are shaped for long sessions, and with over 6'2" of ceiling height, even tall bathers can sit upright on the upper bench without ducking. The CL4G also comes with something most sauna kits in this price range don't: a permanent asphalt shingle roof, front and back floor drains, a full ventilation system, and a premium LED lighting kit with Wi-Fi app control — all included, not sold as extras.

Assembly & Installation

The CL4G ships flat-packed on a pallet and is designed for DIY assembly. SaunaLife includes a detailed step-by-step installation manual with the kit.

What to expect:
- 1–2 people can handle the full build
- Plan for a weekend project — most assemblies take 6–10 hours depending on experience
- Basic tools required (drill, level, rubber mallet — no specialized equipment)
- The sauna kit includes all necessary montage hardware, foundation beams, and fascia boards

Electrical requirements:
You'll need a dedicated 240V circuit for your sauna heater. The exact requirements depend on the heater you choose. you'll also need a 120V line for the lights of the sauna.

Foundation:
The CL4G needs a flat, level surface. Concrete pad, paver stones, or a reinforced deck all work. The sauna weighs approximately 650 lbs assembled (before the heater and stones), so make sure your surface can handle it.

SaunaLife Shipping Information

General Delivery Information (Applies to Both)

All deliveries require a scheduled appointment. The sauna will arrive protected on a wooden pallet, sometimes encased in wood. Prior to shipping this product, we often contact customers to share shipment details and needs and discuss any extenuating delivery circumstances that may complicate or cause additional delivery expenses. Our goal is to ensure your project’s success.

Flat Rate Freight (LTL Truck)

The driver is responsible for curbside delivery only and will lower the items to ground level.

Exception for SaunaLife G3 & G4: These models are too long for lowering. In these cases, the customer is responsible for hand off-loading (piece by piece) or for off-loading with a forklift.

Flat Rate Freight (Flat Bed Truck)

For this option, the driver provides "delivery only" with limited assistance at the site. The customer is entirely responsible for removing the sauna crate from the truck.

Required Equipment: You must provide a forklift or crane to offload the crate.

Note: On rare occasions, remote or complex delivery areas may not qualify for these rates.

Step 1

Set it up once

DIY-friendly kit designed for a weekend build with two people.

Step 2

Choose your heat

Harvia for reliable and budget-friendly, HUUM for richer steam, we help you decide.

Step 3

Make It a Ritual

The included Sauna Mastery Protocol locks in session times, temperatures, and weekly rhythm, so the sauna becomes a habit, not an expensive coat rack.

Enjoy “Traditional Sauna” Heat & Benefits in Your Backyard.

Even heat, top to bottom

Rounded interior corners and bench geometry move heat the way a barrel does — no cold floor zone, no scorched ceiling.

Stand-up cabin headroom

6'2" of interior height. You can sit, stand, and stretch out, even if you're tall.

Premium features come standard. Not as add-ons.

Roof, drainage, ventilation, and Wi-Fi LED lighting are engineered in. Most kits at this price ship without any of these.

Real outdoor durability

1.7" Thermo-Spruce shell handles freeze, thaw, sun, and rain — no tarps, no annual sealing, no chemical treatments.

Thermo-Spruce built for decades of exposure.

Built to Last Outdoors

The shell is 1.7-inch Thermo-Spruce — spruce baked at 400°F+ in an oxygen-free, steam-rich kiln. The process permanently changes the wood's cell structure: it breaks down the parts that absorb moisture, drives out the resin, and leaves wood that won't warp, crack, or rot outdoors.

No chemicals. No pressure treatment. Just heat and steam.

It's the same process used in high-end European outdoor architecture — and why SaunaLife backs the CL4G with a limited lifetime warranty.

Built to handle whatever nature throws at it.

Engineered Roof & Ventilation

The CL4G comes with an asphalt shingle roof — the same roofing material used on houses. Most sauna kits in this price range ship with no roof at all, or a thin temporary cover that needs replacing within a year or two.

The CL4G also includes front and back floor drains, a full ventilation system with back vents that create a natural chimney effect, and a premium LED lighting system with Wi-Fi app control.

Interior Comfort

Engineered for 30 minutes of comfort. Not just a photo op

Cool-Touch Thermo-Aspen

Knotless Thermo-Aspen benches stay comfortable even at full sauna temperatures — no towel barrier needed.

Contoured Ergonomic Seating

Shaped bench and arched backrest hold you in place at minute 15, no shifting around.

6'2" Interior Headroom

Even tall bathers can sit fully upright on the upper bench without ducking.

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..

What sauna owners are saying

STILL UNSURE?

Frequently Asked Questions

Does the SaunaLife CL4G come with a heater?

No — the CL4G is a sauna shell kit. The heater and sauna stones are sold separately. This is actually an advantage: you get to choose the heater that fits your preferences and budget instead of being stuck with whatever comes bundled. We recommend a 6–8 kW electric heater. Our top picks for this model are the HUUM DROP 7.5kW (premium, designer look, smart home integration) and the Harvia KIP 6kW (proven workhorse, more affordable).

Can I install the SaunaLife CL4G myself?

Yes. The CL4G is designed as a DIY kit and ships with a detailed installation manual. Most customers complete the build with 1–2 people over a weekend (6–10 hours). The sauna assembly itself requires only basic tools — drill, level, rubber mallet. You will need a licensed electrician to wire the heater circuit (240V, 30–40A dedicated line depending on your heater choice). Budget $200–$500 for the electrical work.

What is thermally modified wood and why does it matter?

Thermo-Spruce and Thermo-Aspen are heated to extreme temperatures (400°F+) in an oxygen-free environment. This permanently changes the wood's cell structure, making it naturally resistant to moisture, decay, warping, and insects — without any chemical treatments. It's the same thermal modification process used in high-end European architecture. This is why SaunaLife uses it for both the exterior (Thermo-Spruce) and the interior benches (Thermo-Aspen), and why they back it with a limited lifetime warranty.

What kind of roof does the SaunaLife CL4G have?

A permanent asphalt shingle roof — the same roofing material used on houses. Most outdoor sauna kits in this price range ship with either no roof at all or a thin temporary cover that degrades within a year or two. The CL4G's roof is built to last through all four seasons with no additional roofing work required.

How much does it cost to run the SaunaLife CL4G?

A typical sauna session includes heat-up time plus the session itself. With a 6–8 kW electric heater, expect roughly 30–45 minutes of heat-up at full power, then another 30–60 minutes for your actual session where the heater cycles on and off to maintain temperature. Total energy per session is roughly 7–10 kWh. At the US average electricity rate of $0.12–$0.17 per kWh, that's roughly $1–$1.70 per session. Three sessions a week puts you at approximately $12–$20 per month depending on your heater size, session length, and local rates. That works out to about $3–$5 per session — still less than a single coffee shop visit for a full sauna experience at home. Over 10 years of regular use, the total operating cost is roughly $1,400–$2,400. Compare that to a gym membership with sauna access at $50–$100/month ($6,000–$12,000 over the same period).

How much space do I need for the SaunaLife CL4G?

The CL4G exterior footprint is 80.7 inches wide × 49.2 inches deep × 82.7 inches tall (roughly 6'9" × 4'1" × 6'11"). You'll want at least 12 inches of clearance on the sides and back for ventilation and maintenance access. The sauna needs a flat, level surface — concrete pad, paver stones, or a reinforced deck all work. Total space needed: approximately 8' × 6' minimum.

What's the difference between the SaunaLife CL4G and CL5G?

Both have the same panoramic glass front and Thermo-Spruce construction. The CL5G is deeper (59.1 inches vs 49.2 inches), seats 4 people instead of 3, and weighs about 170 lbs more. If you regularly sauna with more than 2 people or want room to fully stretch out, the CL5G is worth the step up. If you're primarily using it solo or as a couple, the CL4G is the sweet spot.

Does the SaunaLife CL4G work in cold climates and winter?

Yes. The 1.7-inch Thermo-Spruce walls provide solid insulation, and the ventilation system is designed to work efficiently in cold weather. Customers use the CL4G year-round in northern climates. A 6–8 kW heater will reach full sauna temperature (150–185°F) even in freezing conditions — it may just take a few extra minutes to heat up in winter vs. summer.

What does the SaunaLife CL4G warranty cover?

SaunaLife covers the CL4G sauna environment with a limited lifetime warranty. This covers defects in materials and workmanship. As an authorized SaunaLife retailer, Topture fully honors and facilitates all warranty claims — you deal with us, not the manufacturer. The heater has its own separate warranty from the heater manufacturer (HUUM or Harvia, depending on which you choose).

How is the SaunaLife CL4G delivered?

The CL4G ships flat-packed on a pallet via freight truck (1,415 lbs shipping weight). Delivery is curbside — the driver will bring the pallet to your driveway or curb. Every Topture order includes full-value freight insurance at no extra charge. If anything arrives damaged, contact us and we handle the claim. You'll need a way to move the components from the curb to your build site — most customers use a hand truck or dolly.
