Sun Home manufactures the saunas and cold plunges named in this guide. Specifications and prices were checked against the sources named in the Methodology and Sources section on September 22 and 23, 2026; "not found" means the figure was not found in those sources on those dates, not that it does not exist. Figures are labeled manufacturer specification, calculated from stated inputs, or illustrative assumption where the difference matters.
Short Answer
Plan an accessible home sauna around the user's entry, transfer or roll-in method, seating, controls and exit. Measure the complete layout and identify which accessibility standards apply to the project. Published cabin dimensions alone do not establish accessibility; a custom room may be needed when a prefabricated cabin cannot meet the person's verified requirements.
Key Takeaways
- Start with the person, not the cabin: wheelchair roll-in, transfer from a chair to a bench, ambulatory use with a walker or cane, limited reach, or assisted use are different tasks with different measurements.
- The ADA Standards give the best-documented reference dimensions for saunas (sections 241, 612, 903, 304, 305, 404, 308 and 309). Whether they legally apply to your project is a separate question for the authority having jurisdiction; ordinary private residential use is generally outside the ADA, but a home used as a rental or a business may not be.
- In the ADA sauna provisions the transfer space is a 30 by 48 in clear floor space at the end of the bench, parallel to the bench's short axis, and the turning space (a 60 in circle or a compliant T-shape) is inside the sauna.
- Sun Home does not label any cabin wheelchair accessible. Published door widths (28 in Equinox and Solstice, 24 in Luminar, 29 in Solaris) are narrower than the 32 in reference, and the Equinox and Solstice bench height (19.5 in) sits above the 17 to 19 in reference; thresholds, bench transfer details and turning space are unverified rather than proven inadequate.
- Requirements and recommendations are kept separate on this page. Rails, seat-height rules and app controls are individualized options, not universal compliance measures.

The U.S. Access Board's sauna and steam room guide explains these provisions with drawings. Scoping (section 241) covers saunas provided in facilities the Standards apply to; clusters require at least 5 percent, and no fewer than one, of each type to comply.
Dimension Checks Against Sun Home's Published Figures
| Feature | Reference value | Equinox 2 and 3, Solstice 2 and 3 | Luminar 5 | Eclipse 2 and 4 | Solaris 4 | Assessment status |
|---|---|---|---|---|---|---|
| Door clear width | 32 in | 28 in | 24 in | Not found | 29 in | Published widths are below the reference; Eclipse unverified |
| Threshold height | 1/2 in | Not found (cabins sit on a raised floor; Solstice on 2 in feet) | Not found | Not found | Not found | Unverified; measure the step at the door |
| Turning space inside | 60 in circle or T | Interior 45.4 x 39.9 in (2) and 56.8 x 39.9 in (3): a 60 in circle cannot fit; a T-shape is not established | Interior 78 x 47 in with an L-shaped bench: a 60 in circle cannot fit; a T-shape is not established | Interior 42.8 x 42.2 in (2) rules out a 60 in circle; 85.7 x 50 in (4) with removable benches: a 60 in circle cannot fit; a T-shape is not established | Interior 76 x 66 in: unverified; benches, heater and door swing not laid out | Every interior except the Solaris 4 is under 60 in in one direction, which rules out a 60 in circle; the Solaris 4 and any T-shape need a layout drawing |
| Bench height | 17 to 19 in | 19.5 in | Not found | Not found | Not found | Equinox and Solstice are 0.5 in above the reference; others unverified |
| Bench length and depth | 42 in long, 20 to 24 in deep | 45.2 or 56.6 in long, 20.2 in deep | 59 and 44 in segments, 20 in deep | Not found | Not found | Published Equinox, Solstice and Luminar benches meet the length and depth reference |
| Bench clear floor space (30 x 48 in at the bench end) | Parallel to the short axis | Not established: interior depth is 39.9 in | Unverified | Unverified | Unverified | Needs a plan drawing with benches, heaters and door swing |
| Fixed bench with back support | Required for the accessible bench | Fixed benches; back support not documented | Not documented | Removable benches: a removable bench is not an accessible transfer bench | Not documented | Ask Sun Home for bench construction details |
| Controls | One-hand operation within reach range | Control pad; mounting height not published | Panel plus app | Panel plus app | HUUM UKU; mounting height per installation | App control can help a user with limited reach but is not a compliance substitute for a physical control within reach |
"Not found" means the value was not in the Sun Home pages checked on September 22 and 23, 2026. A missing value is unverified, not a proven failure; a simple interior rectangle cannot establish clear floor space or turning space when heater towers, doors and seating are not drawn.
Sun Home Model Limitations, Stated Plainly
- No Sun Home cabin is labeled wheelchair accessible, and none publishes a threshold height, a transfer-bench detail, a control mounting height or a turning-space drawing.
- Published door widths (24 to 29 in) are below the 32 in reference. That rules out a roll-in for most wheelchairs; it does not by itself rule out ambulatory use, transfer use with assistance, or a user who enters on foot and sits.
- Equinox and Solstice 2 and 3 benches (19.5 in high, 20.2 in deep, 45.2 or 56.6 in long) are close to the transfer-bench reference on height and meet it on length and depth, but they have no documented back support or grab bar provision and no verified clear floor space at the bench end.
- Eclipse benches are removable. The Standards' exception lets readily removable benches obstruct turning and clear floor space, but the accessible bench itself must be fixed or built in; a removable bench does not become a transfer bench.
- Grab bars cannot be added to a cabin's panels without the manufacturer confirming the attachment; ask Sun Home before drilling anything.
Controls, Reach and Assisted Exit
- Measure the user's seated reach and compare it with where the control pad will be mounted; Sun Home does not publish the height, so measure the cabin or ask support.
- App control (Eclipse, Pod, Luminar; HUUM UKU Wi-Fi on Nova and Solaris) lets a helper or the user set temperature and timers from a phone. Keep a physical control within the user's reach as well.
- Sauna doors open outward and do not latch; confirm that the user can open the door from the bench or that a helper is present, set a session timer with automatic shutoff, and keep a call device within reach.
Measurements to Send a Designer
- The user's mobility device dimensions and turning needs, or their walking aid.
- Transfer method and preferred seat height (from the user's chair or therapist).
- Seated reach range, both hands, and any grip limitation.
- The route to the sauna: door widths, thresholds, floor surfaces, lighting.
- The cabin's manual and any drawing Sun Home supplies: door, threshold, bench, heater and control positions.
When a Custom Room Is the Answer
When the user's verified needs include a 32 in clear roll-in door with a level threshold, a fixed transfer bench with back support and 30 by 48 in of clear floor space at its end, a 60 in turning circle or compliant T-shape inside the hot room, grab bars anchored to blocking, and controls mounted at a reachable height, a site-built room designed with an accessibility specialist is the route. A stone heater sized to the room's adjusted volume can be specified through Sun Home's traditional sauna buying guide; confirm heater-package availability with Sun Home before designing around it.
Bottom Line
Define the user's access method first, use the ADA sauna provisions as the reference dimensions, and test each cabin against a full layout, not a rectangle. On Sun Home's published figures, door widths (24 to 29 in against a 32 in reference) and the Equinox and Solstice bench height (19.5 in against 17 to 19 in) are the clear shortfalls; threshold, transfer space and turning space are unverified and should be requested. Where verified needs exceed what a prefabricated cabin can meet, plan a custom room and have an accessibility specialist review the drawings.
Frequently Asked Questions
Does a wide door prove a sauna is accessible?
No. Door width is one of several checks; bench transfer space, turning space, threshold, controls and exit all matter, and they are judged together on a layout drawing.
Can a removable bench solve the layout?
It can free turning or clear floor space under the Standards' exception, but the accessible bench itself must be fixed or built in. A removable bench is not a transfer bench.
Can app controls replace physical controls?
They help a user or helper, but a physical control within reach is still needed; app control is not a compliance substitute.
What measurements should I send the designer?
The user's device or aid dimensions, transfer method and seat height, seated reach, the route to the sauna, and the cabin's door, threshold, bench, heater and control positions.
Methodology and Sources
Reference dimensions are taken from the 2010 ADA Standards for Accessible Design as explained in the U.S. Access Board's sauna guide; legal applicability is not assessed here. Sun Home dimensions were read on its product and help-center pages on September 22 and 23, 2026, and unverified values are marked as such rather than treated as failures. The statement that no Sun Home cabin is labeled wheelchair accessible reflects Sun Home's current pages and should be confirmed by its product team. An accessibility specialist should review the standards interpretation before publication. Sun Home manufactures the cabins named.
