Sun Home Sauna Sizing Guide: Which Model Fits 1, 2, 3, 4 or 5 People?

Sun Home Sauna Sizing Guide: Which Model Fits 1, 2, 3, 4 or 5 People?

Updated July 30, 2026: this guide reflects current model dimensions, weights, electrical requirements, materials, controls, and traditional-sauna availability. Next scheduled review: October 2026.

Direct Answer

The right Sun Home sauna size depends on the number of regular users, desired heat type, available room dimensions, bench space, and electrical service. Listed capacity is the maximum designed seating count, not always the most comfortable daily-use count. For one person, compare the Solstice 1 and Pod. For spacious solo use or two average-build adults, compare the Equinox 2 and Eclipse 2. Couples wanting additional shoulder room should consider the Equinox 3. For families and groups, compare the larger infrared and traditional models by bench arrangement, exterior footprint, clearances, assembled weight, and circuit requirements. Before ordering, verify the complete delivery route and the current model specification sheet.

Disclosure: Sun Home manufactures the products covered in this guide. Technical fields are drawn from current product documentation; comfortable daily-use recommendations are editorial judgments and are labeled separately.

Best Sauna Size by Number of Regular Users

Published Size and Installation Specifications

Fields below come from current Sun Home product pages and spec sheets. Where a value is not published on a Sun Home source, the cell says so rather than carrying an estimate.

Size and fit

Weight verification status

Weight affects deck approval, structural engineering, roof-terrace placement, delivery planning, and floor-load calculations, so use the conservative figure until the specification sheet is confirmed in writing.

Electrical, heat, and features

The Eclipse 2 is the exception buyers miss. It runs on 120V, which reads as a standard household installation, but it draws 23.5A through a NEMA L5-30P locking plug on a dedicated 30A circuit. Every Sun Home model requires a dedicated circuit; none is rated for a shared household outlet.

Listed Capacity Versus Comfortable Daily Use

Three different claims get collapsed into one number in this category, and separating them is the most useful thing a sizing guide can do:

• Listed capacity — the manufacturer's maximum designed seating count.
• Recommended daily capacity — Sun Home's editorial comfort recommendation, which is a judgment, not a specification.
• Physical seating evidence — interior width, bench length, bench depth, and bench arrangement. This is the only one you can measure.

Our methodology. Comfortable daily-use recommendations are editorial judgments based on published interior dimensions, bench dimensions, seating configuration, and the ability of regular users to sit without unwanted shoulder contact. Body proportions and preferred seating position vary, so compare the model's bench dimensions against your own seated space requirements rather than relying on the person-count label.

A practical check: measure your seated shoulder width, add your partner's, add roughly four inches of clearance, and compare that against the published bench length. On the Eclipse 2, that bench is 42.8 inches; on the Solstice 3, it is 56.6 inches. Two adults at 18 inches of shoulder width each plus clearance fit on the Eclipse 2 bench; two broader adults will be in contact.

Traditional models need a separate reading. The Nova and Solaris use stacked upper and lower benches, which is not directly comparable to the single-level bench in most infrared cabins. Upper-bench seating is hotter and typically preferred, so a stacked 5-person cabin does not seat five people in equivalent conditions. Evaluate the bench arrangement, not the headline count.

How to Measure Your Room and Delivery Path

1. Footprint plus clearance. Add the published side clearance to the exterior width and depth, and the overhead clearance to the height. On the Luminar models that overhead figure is 20–24 inches, which often governs under a covered patio or soffit.
2. Ceiling height. Exterior heights run 76.7 to 84 inches before clearance. A basement with ducting can fail on height alone.
3. Delivery route, not destination. Measure doorways, stair turns, gates, elevator cars, and ceiling height along the whole path. Crated dimensions exceed assembled dimensions.
4. Placement versus curbside. On heavier models, confirm whether delivery includes final placement and whether specialized equipment or an installation crew is required.
5. Floor and load. Assembled weights run 385 to 1,270 lbs. Slab-on-grade is generally the simplest placement condition, subject to slab condition, local requirements, and the model's installation instructions. Framed floors, decks, and roof terraces warrant a structural check at the upper end.
6. Receptacle position. The Eclipse 2 ships with a 9-foot cord and extension cords void the warranty, so the outlet location is part of the layout.
7. Water sources. The warranty requires at least five feet between the sauna and a cold plunge, shower, tub, or anything producing liquid or vapor (warranty terms).

Frequently Asked Questions

Is a 2-person sauna actually big enough for two people?

For two average-build adults, usually yes. For two broader or taller adults sitting together regularly, often not comfortably. The Eclipse 2's bench is 42.8 inches long — workable for two adults at roughly 18 inches of seated shoulder width each, tight above that. Compare the published bench length against your own measurements rather than trusting the person-count label, and consider a 3-person model if either user is larger than average.

What sauna size should a couple buy?

If both partners are average height and build and will use it together regularly, a 2-person model works. If either is taller or broader, or if you want the option to lie back or change position, the Equinox 3 and Solstice 3 add 11.4 inches of width at the same depth and height. For traditional heat, the Nova 3-Person uses stacked benches, which changes the seating comparison entirely.

Should I buy a larger sauna than I need?

Not automatically. Sizing up costs footprint, ceiling clearance, delivery difficulty, assembled weight, preheat time, and sometimes a larger circuit. Size up when a regular user is taller or broader than average, when you expect a third person regularly, or when you want room to change seated positions. Otherwise the smaller cabin heats faster and installs more easily.

Which Sun Home sauna fits in an apartment?

The Solstice 1 at 37.8 × 39.8 inches and the Pod at 40.1 inches in diameter have the smallest footprints, both on a dedicated 120V/20A circuit at 428 and 385 pounds respectively. The dedicated circuit is usually the binding constraint in a rental, not the floor space — confirm you can add one before ordering, because a shared household outlet voids the warranty.

Which models run on 120V and which need 240V?

120V: Solstice 1, 2, and 3, Equinox 2 and 3, Pod, and the Eclipse 2 — though the Eclipse 2 needs a dedicated 30A circuit and a NEMA L5-30P locking receptacle despite the 120V rating. 240V: Solstice 4 (20A, NEMA 6-20P), Eclipse 4 (30A), Luminar 2 (20A), Luminar 5 (30A), Nova 3-Person (30A), and Nova 6-Person (40A). All require a dedicated circuit.

How tall is the Pod?

77.5 inches exterior height, with a 72-inch interior height and a 35.4-inch interior diameter inside a 40.1-inch outside diameter. Use the exterior figure plus clearance when checking a basement or low-ceiling room, since the interior height is roughly five and a half inches shorter and is sometimes quoted in its place.

Which Sun Home models have red light therapy?

Factory-integrated on the Eclipse 2, Eclipse 4, and Pod. Optional as an add-on on the Luminar. Not offered on the Equinox, Solstice, Nova, or Solaris. If red light matters, it should narrow your shortlist before size does, because it eliminates most of the lineup.

Which Sun Home saunas have app control?

The Sun Home app is available on the Eclipse, Pod, and Luminar, with remote preheat, scheduling, session control, and guided breathwork. The Equinox and Solstice use an onboard digital control panel with a programmable timer and reservation mode — no app connectivity. The Nova and Solaris use the HUUM Wi-Fi app for temperature and scheduling.

How much floor load should I plan for?

Use the model-specific assembled weight distributed across the footprint, plus occupants. Pod 385 lbs, Solstice 1 428 lbs, Equinox 2 520 lbs, Eclipse 2 600 lbs, Nova 3-Person 772 lbs, Eclipse 4 925 lbs, Nova 6-Person 926 lbs, Luminar 5 1,270 lbs. For the Luminar 2, design to 970 lbs pending written confirmation. Verify against the current spec sheet at order, since specifications update between production runs.

Are traditional and infrared capacities comparable?

Not directly. The Nova and Solaris use stacked upper and lower benches, so a listed capacity spreads users across two heat zones at different temperatures rather than seating everyone side by side. Most people prefer the upper bench. Read the bench arrangement and the interior dimensions rather than comparing person-count labels across heat types.

Source Ledger

Open verification items. Three fields currently carry conflicting values across Sun Home sources and are marked accordingly above: the Luminar 2 assembled weight and the Solaris Small amperage. Confirm each on the current spec sheet before ordering, and design to the conservative figure where load is involved.

Bottom Line

Person-count labels are a starting point, not a specification. The four numbers that determine fit are bench length, exterior footprint plus required clearance, assembled weight, and circuit amperage. Pull those four for the models on your shortlist from the tables above, measure your own seated shoulder width and your room, confirm the delivery path, and verify the circuit before you order.

Methodology

Dimensions, weights, clearances, bench sizes, door openings, and electrical requirements are taken from current Sun Home product pages and downloadable spec sheets, each linked in the source ledger above, and are dated because they change between production runs. Where a value is not published on a Sun Home source, the cell reads "Not publicly published as of July 30, 2026" rather than carrying an estimate. Where two Sun Home sources disagree, the conflict is named and a conservative design figure is given for any load-bearing number. Comfortable daily-use recommendations are editorial judgments based on published interior and bench dimensions and seating configuration, and are labeled separately from manufacturer specifications throughout. Prices are not published in this guide because they change with promotions; current pricing is on each product page.
