Pricing Considerations

The SaunaLife CL3G Outdoor Cube Sauna (2 Person) is priced at $4,940, making it the more budget-friendly option for homeowners seeking a premium outdoor sauna without requiring a large installation footprint. In comparison, the SaunaLife CL5G Outdoor Sauna Cabin (4 Person) is priced at $6,940 and offers significantly more interior space, greater capacity, and a more luxurious outdoor wellness experience.

While the CL5G requires a higher upfront investment, it can provide better long-term value for families who plan to use the sauna with guests on a regular basis. The CL3G, on the other hand, is often the preferred choice for solo users or couples who want lower operating costs, faster heating times, and a more compact installation. When comparing these models, homeowners should consider not only the purchase price but also how frequently the sauna will be used, the number of expected users, and their long-term wellness goals.

Dimensions and Sizing Considerations

Before choosing between the CL3G and CL5G, carefully measure your available outdoor space and account for clearance around the sauna for ventilation, maintenance access, and installation. The CL3G is ideal for compact backyards, patios, and limited outdoor areas, while the CL5G is better suited for larger properties where a dedicated wellness or entertainment zone is planned. Selecting the right size ensures comfortable use without overwhelming your outdoor space.

How Much Space Do You Actually Need?

While dimensions should not be the only factor in your decision, understanding the physical footprint of each sauna can help ensure a better fit for your outdoor space.

SaunaLife CL3G Dimensions

• Exterior dimensions - 51.2" deep (130 cm), 53.2" wide (135 cm), and 81.9" high (208 cm)

• Interior dimensions - 43.2" deep (110 cm), 49.6" wide (126 cm), and 75.4" high (192 cm)

• Interior dimensions - 55.1" deep, 77.2" wide, and 74.8" high

For most Sauna owners, the decision comes down to usage rather than measurements alone.

If you're buying primarily for yourself or your partner, the CL3G provides a comfortable sauna experience without consuming unnecessary backyard space.

If you're buying for your family, expect regular use by three or more people, or are creating a dedicated outdoor wellness area, the CL5G offers the additional room and flexibility that larger households typically prefer. 

How to Choose the Right Sauna Size for Your Lifestyle

Many homeowners assume that choosing between the SaunaLife CL3G and CL5G is simply a matter of comparing dimensions. In reality, the better approach is to think about who will use the sauna most often and how your wellness routine may evolve over time.

Choose the CL3G If:

• You primarily want a personal wellness retreat

• Most sessions will involve one or two people

• You have limited backyard space

• You prefer faster heating and lower operating costs

• You are purchasing your first outdoor sauna

For solo users and couples, the CL3G provides an excellent balance of comfort, efficiency, and affordability without taking up unnecessary space. 

Note: If you're buying a sauna for yourself or for use with your partner, the CL3G is the better choice 

Choose the CL5G If:

• Multiple family members will use the sauna regularly

• You frequently entertain guests

• You are building a dedicated backyard wellness area

• You want extra room to stretch out during sessions

• You want a sauna that can accommodate future lifestyle changes

Many homeowners who expect long-term family use find that choosing a larger sauna upfront helps avoid outgrowing the space later.

Note: If it will be used by your family or you expect more people to use it in the future, the CL5G is the better option.

Choosing the Right Heater for Your Sauna

The heater plays a critical role in the overall sauna experience. While both the CL3G and CL5G support high-quality electric sauna heaters, individuals or families should select a heater based on sauna volume, usage frequency, and desired heat-up times.

For the CL3G

Because of its smaller interior volume, the CL3G typically benefits from a lower-capacity heater that can bring the sauna to operating temperature quickly while maintaining energy efficiency.

Ideal for:

• Daily use

• Short recovery sessions

• Couples or solo users

Real-World Purchasing Considerations

Many people considering an outdoor sauna initially focus on sauna size but later realize that usage patterns matter more. If the sauna is primarily used by one or two people for regular wellness routines, the CL3G often delivers the best balance of cost, efficiency, and convenience. However, homeowners planning to entertain guests, create a luxury backyard retreat, or accommodate family members frequently find the CL5G to be a more future-proof investment. Considering future lifestyle needs can help avoid outgrowing the sauna after a few years of ownership.

Electrical Planning Before Installation

Electrical & Installation Requirements

Before purchasing either the SaunaLife CL3G or CL5G, homeowners should consider the electrical and installation requirements involved. While both models are designed to simplify assembly, proper site preparation and electrical planning are essential for safe and reliable operation.

Power and Voltage Requirements

The exact power and voltage requirements depend on the sauna heater selected for your installation. Because sauna heaters typically require dedicated electrical service, homeowners should review heater specifications before ordering and verify that their home's electrical system can support the required load.

Before installation, consider:

• Available electrical capacity at the property

• Distance between the electrical panel and sauna location

• Heater-specific voltage requirements

• Future electrical upgrades if needed

• Breaker capacity requirements

• Outdoor-rated wiring and protection

Consulting both the sauna supplier and a licensed electrician before purchase can help prevent unexpected installation challenges.

Site Preparation Requirements

Both the CL3G and CL5G require a stable, level foundation capable of supporting the sauna structure and occupants. Common installation surfaces include:

• Concrete pads

• Paver foundations

• Reinforced deck structures

• Professionally prepared outdoor foundations

The CL3G's smaller footprint makes placement easier in compact backyards, while the larger CL5G may require more dedicated planning space within a backyard wellness area.

Do You Need a Licensed Electrician?

In most cases, yes. Professional electrical installation is strongly recommended for both models.

A licensed electrician can:

• Install dedicated circuits

• Verify power availability

• Ensure local code compliance

• Connect the sauna heater safely

• Confirm proper operation before first use

This helps protect both the sauna investment and the safety of everyone using it.

Installation Planning Costs

When budgeting for an outdoor sauna, sauna owners should consider more than the purchase price alone. Additional costs may include:

• Electrical installation

• Foundation preparation

• Delivery access requirements

• Assembly assistance (if desired)

Planning for these items in advance helps create a smoother installation experience and avoids unexpected expenses later in the project.

Note: Voltage and power requirements will vary depending on the heater selected. Sauna owners should review the chosen heater specifications and consult a licensed electrician before installation.
