Buying a 2-person sauna is different from buying a treadmill. The best model for you depends on how you plan to use it, whether that’s for quiet daily relaxation, recovery after tough workouts, or as a standout feature in a wellness space for clients.
Sunlighten offers many options, so choosing the right sauna involves more than just picking a size. You’ll also need to consider the type of infrared, control style, electrical requirements, materials, and whether you want extras like chromotherapy or built-in audio. This guide highlights the key factors to help you choose a sauna that fits your needs and budget, so you’ll enjoy it for years.

What to Look For
1) “2-person” in real life: solo luxury vs. true two-person comfort
Many “2-person” cabins work best as roomy for one and “cozy for two.” If you want comfortable side-by-side sessions (or space for stretching), you’ll generally prefer the larger 2-person footprint options, like the mPulse Believe, over slimmer cabins. For example, the mPulse Believe exterior footprint is listed around 51.7″ W x 47.6″ D in published spec sheets.
2) Choose your experience first: simple, intense, or smart-guided
Think of Sunlighten’s common 2-person choices like three different “personalities”:
- Signature II: simpler experience focused on far infrared with a straightforward control approach (popular for “set it and sweat” owners).
- Amplify II: full-spectrum add-on heaters for a more intense, performance-leaning session style.
- mPulse Believe: smart sauna with programs and tech requirements (more “wellness toolkit” than “wood box with heat”).
3) Plan your install before you fall in love with a model
Most homeowner regrets come from underestimating:
- Dedicated circuit needs (common for these cabins)
- Clearance space
- Delivery path (tight hallways, stairs, door widths)
- Where the cord/outlet needs to be
For example, published specs for Signature II and mPulse Believe commonly call for a dedicated 120V 20A circuit/outlet.
4) Decide how much tech you want in your wellness routine
If you love app-driven routines and preset protocols, the mPulse line will feel compelling—but it can add requirements. One mPulse Believe spec sheet notes that dual-band Wi-Fi (2.4 GHz & 5 GHz) is required.
If you prefer a quieter, less “connected” experience, a Signature-style cabin can be a better lifestyle fit.
Key Specifications Explained
Infrared type: Far vs. Full Spectrum (and why it changes the vibe)
- Signature II is positioned as far infrared, using Sunlighten’s SoloCarbon heater approach in the Signature line.
- Amplify II includes a mix: spec listings show FIR plus “full spectrum” heaters (and note no floor heaters).
- mPulse Believe uses a multi-range heater configuration (FIR/MIR/NIR) in its published spec sheets.
How to choose (practical version):
- If you want simple + consistent, lean Signature II.
- If you want higher performance in a 2-person footprint, lean on Amplify II.
- If you want guided programs + customization + smart features, lean mPulse Believe.
Power and electrical: what “120V / 20A dedicated” really means
Many people think a 2-person sauna can plug into a regular outlet, but that’s often not the case or not the best option.
Examples from published specs:
- Signature II is commonly listed around 120V / ~2006W / 20A, with a dedicated 20A outlet.
- mPulse Believe is listed around 120V / 2400W / 20A, dedicated 20A.
- Amplify II is listed around 120V / 1880W / dedicated 20A in one spec listing source.
Why this matters: If you don’t have a dedicated circuit for your sauna, you’ll need to budget extra for an electrician and plan for the extra time.
Footprint, height, and bench space: the “comfort math”
Look at three numbers:
- Exterior width/depth = your floor plan reality
- Interior width/depth = whether it feels cramped
- Bench depth = whether you can sit comfortably (and whether lounging is realistic)
Quick comparison (rounded from published specs):
| Signature II | ~50.9″ W x 45.9″ D | 120V / 20A dedicated | Simple far infrared approach |
| Amplify II | ~50.9″ W x 45.9″ D | 120V / 20A dedicated | FIR + full spectrum heaters, “intense” positioning |
| mPulse Believe | ~51.7″ W x 47.6″ D | 120V / 20A dedicated | Smart sauna; Wi-Fi requirement listed |
Materials: Basswood vs. Eucalyptus (what’s actually different)
Sunlighten commonly offers multiple wood options across models. Retail listings for models like Signature II reference choices like eucalyptus and include feature callouts (e.g., SoloCarbon heaters, chromotherapy, Bluetooth).
For most buyers, the decision comes down to:
- Look/feel in your home gym or spa room
- Budget (some wood options can cost more)
- Scent preference (some people strongly prefer a “clean” vs. “aromatic” vibe)
Features that matter (and the ones you can ignore)
Worth paying for (for most people):
- Comfortable bench depth and back support
- Easy assembly system (especially if your space is tight)
- Controls you’ll actually use daily
- A lighting setup that matches your environment (calming vs. energizing)
Nice-to-have:
- Built-in audio (some people still prefer a separate speaker)
- Accessories bundles (good value if you’ll use them)
Sunlighten’s own retail listing for Signature II highlights features such as SoloCarbon heaters, low-EMF positioning, timer options, chromotherapy, and Bluetooth audio.

Budget Considerations
The real cost isn’t just the sauna
Plan for these line items:
- Electrical work
If you need a dedicated 20A circuit added, your cost depends heavily on panel location and routing complexity. - Delivery and placement
Measure:
- Door widths
- Hallways
- Turns/landings
- Stair clearance
Keep in mind that 2-person cabins can be heavy and difficult to move, even if they fit through your doors and hallways.
- Accessories you’ll actually use
If you know you want towels, backrests, a cleaning kit, etc., bundles can be convenient. Sunlighten sells packages and accessories based on sauna model compatibility. - Promo timing
Retail pages sometimes run seasonal promos. For example, one Sunlighten shop collection page mentions a sale ending 12/24/2025.
If you’re shopping around late December, it’s worth checking current promotions before scheduling electrical work.
Price expectations (without guessing)
Some Sunlighten lines publish clear pricing on their shop pages, while others may redirect you to “get pricing” depending on the model/region.
Examples visible on Sunlighten’s shop pages:
- Signature II Eucalyptus has been listed at promotional pricing (e.g., $4,899 sale price / $5,899 regular price on one listing).
- Amplify II pricing is listed on a Sunlighten shop vendor page (e.g., $5,699 Basswood and $5,899 Eucalyptus, with higher regular prices shown).
For mPulse, some reviewers note pricing isn’t always publicly posted in the same way, so buyers often request a quote.
Use Case Scenarios
Scenario A: The affluent homeowner who wants a calm daily ritual
Best fit: Signature II
Why: It’s positioned as a simpler, far-infrared cabin with a feature set that covers the basics (timer modes, chromotherapy, Bluetooth) without turning your sauna into another “device” you manage.
Scenario B: The biohacker who wants guided protocols and “smart wellness”
Best fit: mPulse Believe
Why: It’s built around programmed sessions and multi-range heaters; published specs mention Wi-Fi requirements, which align with its connected feature set.
Scenario C: The athlete or coach who wants intensity in a 2-person footprint
Best fit: Amplify II
Why: The Amplify collection is positioned as full-spectrum focused, and spec listings show added full-spectrum heaters in the cabin.
Scenario D: Luxury real estate developer or interior designer
Your priorities change:
- Visual integration (wood tone, lighting)
- Noise profile (fans, audio)
- Tech simplicity for guests/clients
- Electrical planning during build/renovation
A Signature II or Amplify II is often easier for end users to operate than a smart sauna that requires Wi-Fi and program selection. This isn’t a major problem, but it’s something to consider when planning your design or operations.

Top Recommendations
1) Best “simple luxury” pick: Sunlighten Signature II
Choose Signature II if you want:
- A calmer, straightforward experience
- Strong “set it and sweat” usability
- A 2-person cabin that’s still comfortable solo
Published specs show a footprint around 50.9″ W x 45.9″ D and a dedicated 120V 20A electrical requirement in standard listings.
Retail listings for Signature II also highlight features like SoloCarbon heaters, chromotherapy, and Bluetooth.
Who shouldn’t pick it: If you specifically want smart programs, app-like control, or full-spectrum emphasis, you may prefer Amplify or mPulse.
2) Best “performance intensity” pick: Sunlighten Amplify II
Choose Amplify II if you want:
- A more intense session style (performance/recovery vibe)
- A 2-person footprint similar to Signature II, but with full-spectrum emphasis
Spec listings show FIR + full-spectrum heaters, and note that no floor heaters are on Amplify II.
Pricing is also publicly visible on Sunlighten shop pages (varies by wood type and promos).
Who shouldn’t pick it: If you want the simplest possible control system (or the lowest price in Sunlighten’s 2-person range), Signature II may be the better fit.
3) Best “smart protocols” pick: Sunlighten mPulse Believe
Choose mPulse Believe if you want:
- A sauna that functions like a guided wellness device
- Multi-range heater configuration and preset program concept
- A roomier 2-person footprint
Published specs list a footprint of around 51.7″ W x 47.6″ D and 120V 20A dedicated electrical needs.
Some published spec sheets also call out dual-band Wi-Fi requirements, reinforcing the “smart sauna” nature.
Who shouldn’t pick it: If you hate setup friction (Wi-Fi, program selection) and want a “press one button and relax” cabin.
Where to Buy
1) Buy direct from Sunlighten’s shop (best for promos + official bundles)
Sunlighten operates an official shop with listings for saunas, accessories, and bundles (promotions may be time-bound).
Pros
- Clear official configurations
- Accessory compatibility is easier to manage
- Promo periods are straightforward
Cons
- Some product lines may push you toward “get pricing” rather than a public cart price
2) Authorized dealers (best if you want white-glove delivery guidance)
Many buyers prefer a dealer when:
- Access is tricky (stairs, narrow doors)
- You want coordinated delivery/placement help
- You want local support
You’ll see Sunlighten models sold through specialty retailers as well—confirm you’re getting the exact model/wood configuration and warranty coverage.
3) “Marketplace” listings (be careful)
You may see Sunlighten-related results on large marketplaces, but 2-person Sunlighten cabins aren’t always consistently available there. If you do buy through a marketplace, confirm warranty terms, model year/spec sheet, and return logistics.
