The quiet room for two.
A cedar sauna concept, 5 by 7 feet, designed with a practice platform that folds out of the walls. Made for one large practitioner, and arguably two.
The fit check tells you, on your phone, whether your overhead reach clears the ceiling.

Heat rises. So does the practice.
The platform lives in the walls. Fold it down and the room has a 5 × 6 ft platform two feet off the floor. Fold it away and the floor is clear under the full seven feet.
Platform folded away. The walls read flat. The full 5 × 7 ft floor, 7 ft of height, two 30-inch lanes.
Platform down, 24 in up, the warm mat built in. The room is wider at your shoulders than at the floor.

The coldest air in a sauna is the air you lie in.
Sauna air stratifies; that much is not in dispute. Which is why the reclined half of a class, spent on the floor, is spent in the coolest foot of the room. Lifting the practice surface 24 inches is the entire argument for the platform.
What we can't tell you yet: the actual gradient in this geometry, with two people moving. Published stratification figures come from traditional rooms near 175 °F, not a 105 °F class. The first prototype gets three logged sensors and we publish the curves. The measurement plan →
Just under the ceiling. The hottest air, where nobody practices. Sets the setpoint.
Six inches above the platform. The number we design to; the floor series lives here.
Just off the floor. The coldest air, and the reason the floor series moved up.

A mirror that becomes the teacher.
A full-height studio mirror from inside, for alignment. When the class starts, a teacher appears in it life-size, next to your own reflection, with the platform-height temperature and the clock in a corner. The outside of the cabin is a plain wall.
Suppliers TBD. Any stream you already pay for plays there too, and audio guidance works at any hour.
A garage, a basement, a deck. Planned for no electrician.
Under 8 ft tall, so it fits under a standard ceiling. About 6 ft 1 in by 8 ft 2 in on the floor: two parking-space widths of a garage wall, or a corner of a basement. It is designed to ship flat, with every panel small enough to go through a normal door on its side. The standard build is designed to run on ordinary 120 V circuits, with no dryer outlet and no panel upgrade, to be confirmed with the units. Outside, a small heat pump on a pad, like a mini-split.
Placement and circuits are confirmed with the first units; the room page says what is decided and what is still TBD.
Step in at temperature. Step out. It dries itself.
Set one felt temperature from your phone on the way home. The room is at class heat when you open the door, the platform warm under your feet before you fold it down. The teacher is life-size in the mirror, the temperature and the clock in the corner. Standing series on the clear floor, fold, floor series two feet up in the warm air, savasana, done. Wipe the mat, thirty seconds. The room runs its own dry cycle and shuts off.
Numbers, and the ones we don't have.
Everything tagged TBD is genuinely open. We would rather leave the cell empty than fill it with a guess.
| Footprint | 5 ft wide × 7 ft long interior, 7 ft ceiling. Exterior about 6 ft 1 in × 8 ft 2 in, under 8 ft tall. |
|---|---|
| Practice zones | Standing series on the floor at full height. Floor series on the platform, 24 in up. |
| Platform | Folds out of the walls: a 5 ft × 6 ft surface 24 in above the floor, no legs, wider at shoulder height than the floor. Folded away, nothing sticks out into the standing zone. The fold is not engineered yet TBD · engineering |
| Step-up | The last 12 in of floor at the door stays clear as the step up. The door swings outward, as sauna doors do. |
| Mat | Built into the bench tops. Fitted towel offered as the one accessory. |
| Heat | The heat is where your body is: the platform surface is warm under you for the floor series, and the same panels warm the walls at torso height for the standing series. A heat pump outside the cabin warms the air, so nothing electronic is meant to sit in the heat and the room is designed to run on ordinary 120 V circuits. You would set one felt temperature and the room would do the rest. A 5 kW sauna heater on 240 V stays as the option for sauna-hot sessions TBD · supplier, measured warm-up |
| Target heat | Bikram-class at the platform (studios run about 105°F). Exact temperature and humidity set with a sauna engineer TBD · engineer |
| Mirror wall | The far short end is a full-height studio mirror from inside: a teacher appears life-size in it, among your own reflections, with the platform-height temperature and the timer in a corner. The outside is a plain panel TBD · suppliers |
| Door | Single outswing door on the entry end, so the 12 in landing is enough to step in and out. |
| Media | The guided sequence, your own streaming, the platform-height temperature and a 60-minute session timer with a cool-down prompt, in the mirror, with audio guidance at any hour. Simple LED lighting. Bluetooth audio for the speaker you already own. Why the timer → |
| Power | Designed for ordinary 120 V circuits, no dryer outlet and no panel upgrade, for the standard build. The resistive option adds one 240 V circuit TBD · confirm with the units |
| Shell | Cedar inside. The plan is a US build; suppliers are not chosen yet TBD · suppliers |
Ten parts, one plan.
One model, one setting, one mirror. Every feature, numbered on the drawing.
- Two-zone practice sequenceStanding series on the clear floor at full 7 ft height, then the floor series 24 in up. The practice moves through the room the way heat does.
- The 4-hinge platformA platform that folds out of the walls for the floor series and folds away for the standing series. No legs, and wider at shoulder height than the floor. The fold TBD · engineering
- Built-in mat, one accessoryThe cushioned practice surface is part of the bench tops. A fitted towel sized to the platform is the only add-on.
- Guided session in the mirrorA real teacher's sequence, life-size in the mirror beside your own reflection, so one practitioner's movement cues the other, or YouTube, a music video, any stream. The platform-height temperature stays on screen and a session timer defaults to 60 minutes with a cool-down prompt.
- Light and sound, kept simpleIntegrated LED lighting with a few scenes. Bluetooth audio for the portable speaker you already own instead of a built-in system.
- Heat where the body isThe platform is warm under you; the walls are warm beside you when you stand; a heat pump outside warms the air. Designed for one felt-temperature setting, ordinary outlets, nothing electronic in the heat, and a dry cycle after every session.
- Thermal zoning by designThree logged sensors in the prototype: floor, platform, ceiling. Target heat is Bikram-class at the platform; exact temperature and humidity set with an engineer TBD
- Mirror end wallA full-height studio mirror on the far short end with the teacher life-size in it. Plain outside. Suppliers TBD.
- Door and step-upA single outswing door on the entry end, and 12 in of floor that never gets covered: the step up onto the platform.
- Cedar shell, planned US buildThe plan is US-grown cedar and a US shop. No unit has been built and suppliers are not chosen yet.

Questions.
Is it really for two?
It is one XL model, and the honest framing is: made for one large practitioner, and arguably two. One person of any size has room to spare on the floor and on the platform. Two people of typical size each get a 30-inch lane standing and share a 5 × 6 ft platform, which is wider at shoulder height than the floor. Two large people will be close. We would rather say that than sell you a room for two that is a room for one and a half.
How hot does it get?
The design target at the platform is Bikram-class heat: most Bikram studios run about 105°F. The exact temperature and humidity are being set with a sauna engineer, because heat and humidity compound, and because the floor and the platform will run at different temperatures in this room. We will publish measured numbers from the prototype, not a spec-sheet promise.
Can I buy or reserve one?
Not yet. No unit exists, and nothing is for sale or open for reservation. The first prototype gets built and measured first. The list hears first when that changes.
Can I do a full class, including the poses with arms overhead?
Mostly, with caveats we'd rather state than hide. Adults reach about 1.2 times their height with arms fully extended overhead (source), so a person 5 ft 10 in reaches the 84-inch ceiling. Touching it is allowed: in the balancing postures a palm on the ceiling is a steadying point, like a hand on a studio wall. In the standard 26-posture sequence only two of the thirteen standing postures go fully overhead (half moon and balancing stick); at 7 ft they clear for practitioners up to about 5 ft 8 in with typical proportions, and everyone taller uses a compact-ceiling variation for those two, hands at heart or chin height, the way low-ceiling home practice already does. That is the price of a room that fits under an 8 ft ceiling, and we would rather state it than hide it. See the clearance table.
What is the "4-hinge"?
The fold the numeral in our name stands for. Draw a 4: a wall, a platform, and the line between them. The platform folds out of the wall for the floor series and back into it for the standing series, so the standing floor has nothing sticking out of the walls, and at platform height the room is wider than at the floor. There are no legs; the floor under it stays clear. It has not been engineered yet, and proving it is the first job of the prototype.
Do I need an electrician?
For the standard build, mostly no. It is designed to run on ordinary 120 V circuits, because 107 °F is hot-yoga heat, not sauna heat, and the heat comes from the surfaces next to you as much as from the air. No dryer outlet, no panel upgrade. The sauna-hot option adds one 240 V circuit. All of it is TBD until a unit is on the bench.
Can I pay with an HSA or FSA?
Probably not, and we won't pretend otherwise. A sauna is a personal-use item, the IRS has warned specifically about "wellness" purchases dressed up with a doctor's note, and the HSA and FSA administrators' own eligibility lists say a general-health sauna is not eligible, "which may also apply to saunas intended for more than 1 person." Some buyers with a diagnosed condition may qualify with a Letter of Medical Necessity, and that decision belongs to an independent licensed physician who reviews the individual case and may say no. We do not sell eligibility and we make nothing from the outcome. If you want an honest answer for your own situation, ClinicalSwipe runs a pre-screen and a qualify-or-decline physician review: clinicalswipe.com/check. More on how this works.
