A signature feature, built to belong
Helm Custom Homes: the Galloway House
Residential · Luxury custom home
For an 11,000-square-foot desert-inspired home in the Midwest, Helm Custom Homes wanted a sauna that matched the architecture, not a unit dropped into a finished room. Sunlighten designed a custom infrared sauna for the primary suite, beside the steam shower.
- ~70 sq ft: custom sauna seating two
- 3D: renderings before the build
- Hands-free: install for the builder
Backlit Himalayan salt blocks form the feature wall, with accent lighting under the benches, a hidden cove detail and landscape rock that ties the sauna to the exterior. Helm chose Sunlighten’s installation service. Our team handled the woodworking, lighting and specialty finishes.
The installation process was terrific. Sunlighten's team came out and they were absolute experts. They made it completely hands-free for me as a builder.

Sunlighten infrared built-in
| Heat source | Infrared radiant heaters emit wavelengths that heat the body directly |
| Temperature range* | 100-170°F |
| Ventilation | No special ventilation needed |
| Maintenance | Low; easy to clean |
| Experience | Non-stifling heat can make for comfortable, enjoyable, stress-relieving sessions. |
| How heat works | The body absorbs infrared energy directly; the sauna’s heat can also raise body temperature. |
Traditional sauna
| Heat source | A stove heats the air |
| Temperature range* | 160-200°F |
| Ventilation | Needs proper insulation and ventilation |
| Maintenance | Moderate; wood care and cleaning |
| Experience | The hotter, more intense air can feel stifling and uncomfortable, driving a hard, fast sweat and often shorter sessions. |
| How heat works | An electric or wood-fired heater heats the air, which transfers heat to the body and can raise body temperature. |
