Choosing between the SaunaLife CL4G, CL5G, and CL7G comes down to four practical questions: how much room you have, how many people will use the sauna regularly, whether you want to recline, and whether you prefer looking through the glass or sitting face-to-face.
All three are premium outdoor saunas from the SaunaLife Cube Series, with a curved Scandinavian-inspired profile, full-glass front, thermally modified wood, ergonomic seating, ventilation, drainage, roofing, and integrated lighting. The biggest differences are the footprint and the way the benches shape the experience inside.
Updated buyer’s guide comparing current SaunaLife CL4G, CL5G, and CL7G configurations.
The best model for each buyer
Think about a normal sauna session—not the largest group you might host once or twice. Your regular number of users, preferred view, and reclining habits will point you toward the right model.
Choose the CL4G
Best for solo users, couples, smaller yards, and buyers who want a premium traditional sauna without using more outdoor space than necessary.
- Normally used by one or two adults
- Upper bench faces the full-glass window
- Approximately 76-inch upper bench for one reclining user
- Compact 80.7-inch by 49.2-inch exterior footprint
Choose the CL5G
Best for couples who want more room to move, small households, and buyers who want a more useful lower seating level without moving to a large group sauna.
- Upper bench faces the full-glass window
- Approximately 76-inch upper bench for reclining
- Lower bench is approximately 20.5 inches deep, giving seated users more support than the shallow CL4G lower level
- Extra side seating creates more options for two or three users
Choose the CL7G
Best for families, entertaining, vacation properties, and anyone who values face-to-face seating or two full reclining positions.
- Two long benches face each other
- More comfortable for conversation and group sessions
- Two people can recline at the same time
- Largest and most spacious model in this comparison
See the bench layouts from above
The CL4G and CL5G are designed around the view through the full-glass front. The CL7G changes the experience by placing two long benches opposite each other.
These simplified layouts are intended to explain the seating differences. Use the current technical drawings on each Solaci Home product page when planning your installation.
CL4G vs. CL5G vs. CL7G at a glance
Compare your usual number of users, preferred seating direction, reclining needs, and available outdoor space. Each Solaci Home product page already presents compatible heater-package options for that specific model, so you can choose from the recommended selections when ordering.
| Decision factor | CL4G | CL5G | CL7G |
|---|---|---|---|
| Best for | Solo users, couples, and compact spaces | Couples and small households wanting more seating flexibility | Families, friends, entertaining, and group use |
| Listed capacity | Up to 3 people | Up to 4 people | Up to 6 people |
| Typical everyday use | Most comfortable for 1–2 adults | Most comfortable for 2–3 adults | Most comfortable for families and groups |
| Where users face | Toward the full-glass window | Toward the full-glass window | Toward one another on opposing benches |
| Reclining | Best for 1 reclining user | Best for 1 reclining user with additional seated room | Best for 2 reclining users at the same time |
| Lower seating | Shallow lower bench or step | Deeper lower bench plus side seating | Two full opposing bench runs |
| Footprint | 80.7" W × 49.2" D | 80.7" W × 63" D | 91" W × 86.6" D |
| Main trade-off | Least lower-bench seating room | Does not provide face-to-face seating | Requires the most installation space and the largest investment |
Exterior dimensions and interior space
Measure the area where you want to place the sauna and compare it with the full exterior width and depth below. Remember to preserve practical room around the structure for assembly, roof access, drainage, and future maintenance.
How the footprints compare
- CL4G 80.7" W × 49.2" D
- CL5G Same width as the CL4G, but 13.8 inches deeper
- CL7G Wider and substantially deeper to accommodate opposing benches
| Model | Exterior dimensions | Interior dimensions | What the difference means |
|---|---|---|---|
| CL4G | 80.7" W × 49.2" D × 82.7" H | 77.2" W × 41.3" D × 74.8" H | Most compact depth; ideal where outdoor space is limited |
| CL5G | 80.7" W × 63" D × 82.7" H | 77.2" W × 55.1" D × 74.8" H | Same exterior width as the CL4G with additional depth for more useful lower seating |
| CL7G | 91" W × 86.6" D × 93" H | 87.5" W × 70.8" D × 85.5" H | Largest interior with opposing benches and more open group space |
Bench lengths and seating depths
Bench depth changes how comfortably a person can sit for a full sauna session. This is one of the most important practical differences between the compact CL4G and the deeper CL5G.
| Model | Main bench length | Approximate bench depth | Seating experience |
|---|---|---|---|
| CL4G | Approx. 76" upper bench | Approx. 20.5" upper bench; shallow lower level | Comfortable upper seating and one reclining position; lower level is better suited to stepping, cooling down, or occasional seating |
| CL5G | Approx. 76" upper bench | Approx. 20.5" upper bench and approx. 20.5" main lower bench, plus side seating | More supportive lower seating and more combinations for two or three users |
| CL7G | Two benches at approx. 70.5" each | Approx. 20.5" per opposing bench | Balanced face-to-face seating with one reclining position on each side |
Bench measurements are rounded for easier comparison. Review the current technical drawing on the applicable Solaci Home product page before making a final space or installation decision.
How each Cube feels in real use
Compact without feeling like an entry-level sauna
Best for one or two regular users who want a window-facing sauna with a smaller footprint.
The CL4G makes the most sense when one or two people will use the sauna regularly. Its long upper bench faces the glass and gives one person enough length to recline. The glass front also helps the relatively shallow interior feel visually open.
- Choose it when outdoor depth is limited.
- Choose it for solo use or couples.
- Choose it when one reclining position is enough.
- Move up to the CL5G if you want a genuinely usable lower bench for regular seating.
Consider the CL5G instead if: you regularly sauna with three adults or want someone to sit comfortably on the lower level while another person reclines above.
The best balance for most couples and small households
Best for buyers who want more usable seating depth while preserving the view through the glass.
The CL5G keeps the window-facing upper bench found in the CL4G but adds 13.8 inches of exterior depth. That extra depth creates a more supportive lower bench and additional side seating, making the interior easier to share.
- Choose it if two people want more personal space.
- Choose it for regular two-person and occasional three-person sessions.
- Choose it when one person may recline while another sits comfortably below.
- Move up to the CL7G if two people want to recline at once or face-to-face seating matters.
Why it is the best all-around choice: it adds meaningful seating comfort without requiring the much larger footprint of the CL7G.
The right choice for social sauna sessions
Best for families, groups, and buyers who want opposing benches.
The CL7G changes the experience by placing two long benches opposite each other. Instead of everyone facing the glass, users can sit face-to-face, making the layout better for family sessions, conversation, and entertaining.
- Choose it for regular group use.
- Choose it when two reclining positions matter.
- Choose it for a vacation home or social wellness space.
- Choose it when interior flexibility matters more than keeping the footprint compact.
Consider the space carefully: the CL7G provides the most seating flexibility, but it is substantially larger than both the CL4G and CL5G.
Choose from the recommended heater options
You do not need to calculate the heater size on your own. On each Solaci Home CL4G, CL5G, and CL7G product page, the heater-package selector presents recommended options for that specific sauna model.
Your main decision is which style of heater and controls you prefer. Available selections may include straightforward traditional Harvia packages as well as higher-stone-mass options from brands such as HUUM or Saunum, depending on the sauna model and current package availability.
Choose a traditional Harvia package if...
- You value straightforward operation and traditional Finnish heat.
- You prefer a practical, familiar heater design.
- You want simple built-in controls or an available digital-control package.
- You want a strong balance of performance and value.
Choose a higher-stone-mass package if...
- You prefer a softer steam experience and more exposed sauna stones.
- You want the heater to make a stronger visual statement.
- Wi-Fi or app-based control is important to you.
- You prefer the feel and appearance of HUUM or Saunum options shown for your model.
Solaci Home makes compatibility easier: begin on the sauna product page, select one of the heater packages shown for that model, and contact us if you want help comparing controls, stone capacity, heat style, or electrical requirements.

Our final recommendation
For one or two regular users with limited outdoor depth, choose the CL4G. For most couples and small households, choose the CL5G for its deeper and more useful lower seating. For families, entertainers, or two people who both want to recline, choose the CL7G for its opposing benches.
If both the CL4G and CL5G fit your space, the CL5G is generally the better long-term choice when you value seating flexibility. If the CL7G fits comfortably and group use is part of your plan, its face-to-face layout offers an experience the smaller models cannot replicate.

CL4G vs. CL5G vs. CL7G FAQs
Which SaunaLife Cube is best for two people?
The CL4G is the most compact choice for two regular users. Choose the CL5G if both people want more personal room, if one person frequently reclines while the other sits, or if you expect occasional guests.
Is the CL5G worth choosing over the CL4G?
The CL5G is worth choosing when lower-bench comfort matters. It has the same exterior width as the CL4G but adds 13.8 inches of depth, creating a more useful lower bench and additional side seating.
Do the CL4G and CL5G benches face the window?
Yes. In both the CL4G and CL5G, the main upper bench faces the full-glass front. This lets users look through the window and creates a bright, open feeling inside.
Can two people lie down at the same time?
The CL7G is the best model in this comparison for two simultaneous reclining users because it has one long bench on each side. The CL4G and CL5G are better suited to one reclining user at a time.
How many adults fit comfortably in each sauna?
The listed capacities are up to three people for the CL4G, four for the CL5G, and six for the CL7G. For more personal room, many buyers use the CL4G as a one-to-two-person sauna, the CL5G for two or three adults, and the CL7G for family or group sessions.
Which model is best for entertaining?
The CL7G is the strongest choice for entertaining because its benches face one another. This arrangement is more natural for conversation than the window-facing benches in the CL4G and CL5G.
Which model uses the least outdoor space?
The CL4G is the most compact of the three. Its exterior measures approximately 80.7 inches wide by 49.2 inches deep.
How do I choose the correct heater?
Open the applicable sauna product page and choose from the recommended heater options presented by Solaci Home for that model. Contact us if you want help comparing brands, controls, stone capacity, or heat style.
Does the sauna price automatically include a heater?
The sauna kit and heater selection are configured separately. Select and add one of the recommended heater packages shown on the CL4G, CL5G, or CL7G product page when placing your order.
What type of foundation does a Cube sauna need?
The sauna should sit on a solid, level, stable, and well-draining base. The final foundation method should reflect the installation instructions, local soil and frost conditions, drainage, applicable codes, and your installer’s recommendations.
Can I assemble a SaunaLife Cube myself?
Experienced DIY buyers may be comfortable assembling the sauna structure with adequate help, tools, preparation, and current instructions. Treat it as a multi-person project and reserve all electrical connections for a licensed electrician.
