Cold Plunges Done Right
A cold plunge only works if the water is really cold, really clean, and ready when you are. San Francisco Sauna handles cold plunge installation across San Francisco, built around the gear you never see. We size a chiller to hold your water steady, usually between 39 and 55°F, add a clean-water system so you skip daily chemicals, and pick a quiet filter you can live next to. You choose the tub: cedar for warmth, fiberglass for easy cleaning, or steel for a modern look. A backyard cold plunge is great on its own for recovery, and it pairs perfectly with a sauna for a hot-and-cold routine. We plan the spot, run the power and plumbing, waterproof and set the tub, and dial in the temperature and treatment before we leave, so you can plunge on day one.
Why Go With Us
A plunge only works if the water is cold, clean, and ready, and that comes down to the gear. We size the chiller to your tub, set up a clean-water system, and pick a quiet filter. We are licensed and insured and do the framing, waterproofing, wiring, and finish ourselves, so you plunge on day one. It is one of the many services from our home services, and a lot of clients pair it with a cedar hot tub.

How We Work
From the first drawing to your first steam, we keep it simple and clear.
1. We plan the spot
We pick where the plunge lives, a deck corner, a garage, or a rooftop, and plan the drain, the chiller spot, and the power run. We talk through how cold you like it and how often you plunge.
2. We size the gear
We size the chiller to your tub and target temperature so it holds cold all day, even in a warm spell. We set the clean-water system and a quiet filter so upkeep stays easy.
3. We install and dial it in
We run the power and plumbing, waterproof and set the tub, and test it. Then we set the temperature and treatment and show you the quick weekly routine.

What Affects the Cost of Cold Plunges
A few things set the price of a cold plunge install:
- The tub. Cedar, fiberglass, and steel each cost different amounts to build and finish.
- The chiller. A small one cools a one-person plunge. Colder water or a bigger tub needs a bigger unit and more power.
- Where it goes. An outdoor pad is simple. Garages, finished rooms, and rooftops need more drain, weight, and access work.
- Water treatment. A good clean-water system costs a bit more up front and keeps upkeep low.
- Site work. Power, plumbing, drains, and any decking add to the total.
- Pairing. Adding a sauna shares the layout and site work.
After we see your spot, you get one flat price for the whole install.
Frequently Asked Questions
What should I look for when purchasing a backyard cold plunge?
Look past the tub to the gear that makes it work: a chiller sized to your volume and target temperature, a clean-water system so you are not dosing chemicals daily, and a quiet filter. Also think about where it goes, since drainage, weight, and power all matter. We help you weigh all of it and size it right.
How cold does it get, and will it hold?
With the chiller sized to your tub, the plunge holds any temperature you pick between 39 and 55°F all day, even in a warm spell. You set it once and step in cold every morning, with no ice runs and no guessing.
Is a cold plunge worth it without a sauna?
Yes. A cold plunge stands on its own as a recovery tool for training, soreness, and a clear head. Many clients start with just the plunge. The pairing with a sauna is popular, so we usually ask, since planning both at once beats adding one later.
What is the upkeep like?
Lighter than you would think, and far easier than hauling ice. The clean-water system and filter keep the water clear on their own, so it is mostly a quick check and the odd top-off. We dial it in before we leave and show you the weekly routine.
