Cold . 45 to 55 F

The cold plunge.

Three pools, each five degrees colder than the last. Walk in slowly, breathe out long, and stay for thirty seconds. That is a full plunge. Included in every pass, $42 to $78.

Three pools

Start warm. Work your way down.

Each pool holds four people sitting. Tap anywhere here and watch the water move.

  • 55F

    The friendly one

    Cold enough to wake you up, easy enough for a first visit. Start every visit here.

  • 50F

    The middle

    Where most regulars settle. One to two minutes, shoulders under, hands out of the water if you like.

  • 45F

    The serious one

    Sharp. Thirty seconds to a minute is plenty. Nobody needs three minutes at 45 to feel the point.

How to breathe

The first ten seconds are the hard part.

The cold makes you gasp. That is a reflex, not a problem. Your only job is to make the next breath slower than the last one.

  1. Stand at the edge

    Two slow breaths. In for four, out for six.

  2. Walk in on an exhale

    Step down the stairs while you breathe out. Do not jump, do not dunk your head.

  3. Sit and count

    Shoulders under. Count ten slow exhales. That is about thirty seconds.

  4. Get out calmly

    Stand up, towel off, walk to the lounge. Let your body warm itself.

Start with thirty seconds

Short and often beats long and miserable.

Thirty seconds at 55 F, three times in one visit, is a real cold practice. Add time across visits, not within one. Most regulars land between one and two minutes.

Get out straight away if you feel numb, dizzy or stop shivering in a way that feels wrong. Cold is not a test. Pair the pools with the sauna or the softer steam room so you have somewhere warm to go next.

Filtration, in plain words

Where the water goes when you are not in it.

The whole pool runs through this loop three times an hour. Ines tests it four times a day and writes the numbers on the board by the pools.

Water flows from the pool to a sand filter, then an ultraviolet lamp, then the chiller, then back to the pool POOL SAND FILTER UV LAMP CHILLER BACK TO THE POOL, EVERY 20 MINUTES

Sand filter

Catches hair, lint and anything you can see.

UV lamp

Kills bacteria without a strong chlorine smell, so a small dose is enough.

Chiller

Holds each pool within a degree of its number, all day.

Thirty seconds. You can do that.

Every pass from $42 includes all three pools. Nervous? A guided session walks you in, or book the whole house for your crew.
