- Set it on a flat, stable, waterproof floor, ideally near a floor drain
- On a deck or upper floor, have a builder or engineer confirm the load
- Keep it near a water source and somewhere to drain
- Leave room for the chiller beside the tub, near a 120 V outlet
Installation
Place it, connect it, fill it
The barrel is freestanding. There's no permanent plumbing, and the chiller plugs into a standard outlet.
Place
- Choose a smooth, level spot with no sharp objects underneath
- Indoors, avoid carpet and keep moisture-sensitive items away. Make sure the room is well ventilated.
- Outdoors, choose shade or cover. Long sun exposure shortens the life of the tub.
Connect
- Connect the chiller's quick-connect hoses to the barrel's 3/4 in inlet and outlet
- Check that every hose gasket is seated before you fill
- Plug the chiller into a standard 120 V outlet. Keep other electrical items at least 5 ft from the tub.
Fill & start
- Inspect the tub for damage before filling
- Fill with a hose to about 70%, enough to cover your upper body with your head above water
- Set your temperature on the chiller or in the app

Using & care
Simple to run, easy to maintain
Every session
- Enter feet first, using the step
- Breathe slowly and steadily. Don't hyperventilate or hold your breath.
- Start at milder temperatures and build up gradually
Water care
- Keep the pH between 7.2 and 7.8, and test it regularly
- With a chiller, the filter and ozone help keep water clear. Without one, change the water every 3 to 5 days.
- Keep the cover locked when the tub isn't in use
Tub care
- Wipe the interior with a soft cloth and a mild detergent. Avoid hard bristle brushes.
- Before storing, drain fully, dry and cover the tub
- Don't store or use the tub below freezing
Near the coast? PVC can't rust or corrode, so Dynamic Cold Therapy recommends this barrel for homes within 50 miles of the coast. Prefer a polished metal finish? See the stainless steel barrel.
Cold water is a strong stressor for the heart and lungs. If you have heart disease, an arrhythmia, high or low blood pressure, circulation problems, diabetes or another medical condition, take medication, or are pregnant, check with your clinician first. Never plunge alone or after alcohol, and get out right away if you feel weak, dizzy or unable to control your hands and limbs. Your core temperature can keep dropping after you get out, so warm up gradually. Children should only use it with close adult supervision.
Research
What the research explores
Stress, sleep and wellbeing
A 2025 review of 11 studies with more than 3,000 participants found cold-water immersion may lower stress, improve sleep quality and support quality of life, with some effects changing over time. Read the review
A natural alertness response
Immersion in cold water triggers a measurable rise in noradrenaline, a hormone involved in alertness and focus. Read the study
Recovery and soreness
Reviews of cold-water immersion after hard exercise report lower perceived muscle soreness and better perceived recovery. Read the review
Recovery isn't the same as adaptation. Cold exposure right after strength training may blunt some of the muscle-building response, so if muscle growth is your goal, schedule cold sessions apart from lifting. Read the study

FAQ
Questions, answered
When will it ship?
This is a new 2026 model, and Golden Designs lists it as available from October 2026. We'll confirm your ship date when you order. Chat with us now for the latest timing.
Do I need a chiller?
Not to start. Without one, you fill the barrel with cold water and ice and change the water every 3 to 5 days. A chiller holds your chosen temperature, from 37°F to 85°F, and filters and sanitizes the water as it runs.
Which chiller should I choose?
Dynamic Cold Therapy recommends at least 0.8 HP for this barrel. Choose the 1.0 HP for frequent plunging, faster cooldowns, or a warm room or climate. Both cool and heat, and both run on a standard 120 V outlet.
How cold does the water get?
With either chiller, as low as 37°F (3°C). How quickly it gets there depends on the room temperature and how much water is in the tub.
Do I need an electrician or a plumber?
Usually not. The tub needs no power, and the chiller plugs into a standard 120 V outlet with GFCI built in. You fill it with a hose and drain it through the 1 in drain valve, so plan where the water will go.
Can it go outdoors?
Yes, on a level surface. Choose shade or cover, since long sun exposure shortens the life of the tub. The chiller is rated for indoor or covered outdoor use, and the tub shouldn't be stored or used below freezing.
How heavy is it when filled?
The water alone weighs about 1,210 lb at a full 145 gallons, so plan for well over 1,200 lb before anyone gets in. The manual suggests filling to about 70%. On a deck or upper floor, have a builder or engineer confirm the load.
Should I choose PVC or stainless steel?
Both share the same barrel shape, bench and step. PVC can't rust or corrode, so Dynamic Cold Therapy recommends it for homes within 50 miles of the coast. The stainless steel barrel has a polished metal finish, but keeping it polished takes more care, and salt air or chemicals like chlorine and bromine can corrode it. Chat with us now and we'll help you choose.
