One outlet. One pad. Year-round cold.
Mortise-joined mahogany over a Kohler basin, with the chiller built in. It holds 32°F year-round on a standard 120V outlet — no plumbing, no second circuit, no compromise.
Mahogany Cold Plunge, in detail.
Cold that stays cold
The chiller is built into the cabinet and holds 32°F through summer. No ice runs, no waiting. Lift the lid and it’s ready.
One standard outlet
Plugs into a normal 120V GFCI outlet. Set it on a pad, fill it, plug it in. No dedicated circuit, no plumber.
Mahogany, joined to last
Mortise-and-tenon joinery in solid mahogany, with stainless and brass hardware throughout. It’s built like furniture, because it’s outside every day.
Why cold therapy
What cold can support.
Deliberate cold exposure is one of the most-studied recovery practices of the last decade. The research is promising and still maturing — bodies differ, and outcomes are never guaranteed. We keep the claims careful on purpose.
Recovery
Cold immersion is widely used after hard training to manage soreness and help the body settle.
Alertness
The plunge drives a sharp rise in norepinephrine — part of why the first cold minute feels so awake.
Mood
A lasting lift in mood is one of the most consistent effects people report after deliberate cold.
Resilience
Staying calm in cold water is a daily practice in controlling your stress response on purpose.
Circulation
Cold constricts the vessels, then they reopen as you warm — a flush the body repeats every session.
Inflammation
Cold-water immersion is studied for its effect on swelling and inflammatory markers after exertion.
Metabolism
Cold activates brown fat and asks the body to spend energy holding its core temperature.
Adaptation
Cold gets easier with repetition as your body learns to meet the shock and breathe through it.
Research-informed
What the science says — and doesn’t.
The research on cold immersion is encouraging, not definitive. Different people respond differently, and timing matters. We build the plunge to make a hard practice repeatable — not to promise an outcome.
Cold
- Norepinephrine rises sharply and can feel alerting
- Brown-fat activation is part of active cold research
- Cold tolerance and autonomic control build with repetition
Contrast
- Pairs directly with sauna heat for a full hot-cold cycle
- Rapid shifts between warm and cold are the heart of the ritual
- Often reported as more mood-elevating than cold alone
Recovery
- Long used to manage soreness after hard effort
- Evidence is strongest for how recovered you feel
- Best kept away from right after strength training if muscle growth is the goal
Caution
- The cold-shock response is real — ease in
- Never plunge alone while you are still new to it
- Check with a provider first if you have a heart condition
Yutori cold plunges are general wellness products. We always recommend discussing substantial routine changes with your healthcare provider.
Questions, answered.
- Can a cold plunge really run on a standard outlet?
- Yes. It plugs into a normal 120V / 15A GFCI outlet. The chiller is built into the cabinet — no dedicated circuit, no second 240V line.
- How cold does it get, and does it hold through summer?
- It holds 32°F year-round. The built-in chiller keeps it there through the hottest months — no ice runs, no waiting. Lift the lid and it's ready.
- Do I need a plumber or any plumbing?
- No. There's a thru-hull drain and top-hatch filter access, but no supply plumbing to run. Set it on a pad, fill it, plug it in.
- How many people does it fit?
- One adult, seated and fully immersed, over a Kohler Underscore K-1130 acrylic basin inside the mortise-joined mahogany surround.
- What's the surround made of, and will it last outside?
- Solid mahogany joined with mortise-and-tenon joinery, with stainless and brass hardware only. It's built like furniture, because it lives outside every day.
- How much does the cold plunge cost?
- Pricing is shared in conversation, not posted. Book a tour, plunge in the working unit, then we'll talk specifics.
