Before delivery

Before your CL4G arrives

What should I budget for electrical installation?

Ask a qualified electrician for an itemized quote using your exact heater, control and lighting manuals. Include the cable route, any panel work, trenching or conduit, permits and all connections. SaunaLife requires qualified professionals for heater and lighting electrical work.

Can I move the heater to the other side?

Confirm the layout with your installer before building or wiring. The heater and control manuals govern clearances and sensor placement. Moving the heater can change the cable route and the heat at the benches; plan ventilation with the layout.

How should I prepare for unloading?

Confirm truck access, the unloading method and liftgate capacity with the carrier before the appointment. Plan how you will move the crate from the delivery point to your build area. Have a stable, level foundation with drainage ready for assembly.

How do I identify the glass door and window parts?

Read the exact model's parts list and glass assembly drawings before starting. Sort parts and hardware by the drawing labels, and arrange help to handle the glass. If a part does not match its drawing, send Sauna Marketplace a photo before proceeding.

Not included: an outdoor enclosure for the heater's power unit and controller. Use a ventilated box rather than a sealed one, so heat from the power module has somewhere to go. The two we recommend: power unit, 13" x 13" x 5.1", ventilated, IP65 rated and controller, 8.7" x 6.7" x 4.3", ventilated, IP65 rated. A ventilated box keeps weather off the electronics. It does not add heat, so check your heater's manual for the lowest temperature its power unit may be installed in. That figure changes by model.

A Better Sauna Kit

SaunaLife is owned and operated by industry veterans with staff in Europe and North America.  Over the years, they learned why sauna kits fail and created the cube sauna that can truly last a lifetime.  Sauna kits fail for several reasons, and SaunaLife addressed them all.

Proper Roof – Most sauna kits come with no roof, or a temporary roof.  Worse, most they don’t tell you.  The SaunaLife CL series comes with an asphalt shingle roof like you would put on a house.  The underlayment alone is a better roof than some cheaper kits on the market.  Critically, the roof system has a drip edge to shed water away from the foundation.  A good roof like this also helps keep the heat from escaping out the top of the sauna.

Good Ventilation – Ventilation is critical for sauna performance and the longevity of the sauna.  The CL series has intake and exhaust vents on the back wall.

Floor Drainage – Water is introduced into the sauna in several ways, including cleaning and pouring water on the rocks to create steam.  Good drainage is important and SaunaLife has drains in the front and back of the sauna.

Unrivaled Comfort

Every detail was considered to ensure exceptional comfort including contoured seating surfaces and supportive arched backrests, so you’ll be comfortable even after long sauna sessions. Satin-smooth thermo-aspen seating provides cool-to-the-touch surfaces to ensure that you will have a relaxing and enjoyable sauna experience. The expansive glass front wall adds a bright, airy feeling, and a picturesque view of the outdoors.

Robust Construction

Premium quality materials are evident everywhere on Cube-Series Saunas. The exterior wood is made from durable full-length staves that have been organically thermally enhanced. This Thermo-Spruce wood is stronger, more dimensionally stable, naturally resists decay and pests, and will far outlast conventional wood. A complete shingle kit with drip rails ensures superior water management and a dry interior. The bronze-tinted 0.3in thick front door is both beautiful and tempered for your safety.

Premium Experience Enhancements

Gently illuminating this spectacular sauna is app-based, Wi-Fi controlled premium “dotless” LED lighting. The elegant indirect lighting brings out the natural beauty of the wood and adds another dimension to your relaxing sauna.

Create a backyard spa experience like no other with a Cube-Series backyard sauna and live the SaunaLife!

How Does it compare to similar sauna kits?

Ask a Builder

We asked our builder friend who has assembled every popular sauna kit on the market, how does the CL4G compare?  Here's what he said.

Saunalife front glass is already installed in the frame. So, no putting a puzzle together or using silicone to seal it. Saunalife uses a riser rather than the cradles so in my opinion easier. The back wall is pretty much the same going together. Saunalife uses a set of filler staves that are already pre cut so there's now sawing or trimming to fit, that would only happen in a rare case. Saunalife straps already have the buckles installed saving even more time.everything else is pretty much the same
