0.3 HP Ice Bath Unit with Seated Tub

The 0.3 HP Ice Bath Unit with Seated Tub is an entry‑level cold‑water immersion system engineered for spaces where a larger chiller would be impractical. It runs on a standard household outlet, holds water at a steady 5 °C for volumes up to 300 litres, and weighs only 19 kg. The system includes a water purifier with replaceable filter cartridges, a circulation pump, and an inflatable seated tub.

Muke Intelligent Technology (Shandong) Co., Ltd. has refined the 0.3 HP chiller through multiple design generations. It is now a mature product, recognised for its stable cooling and quiet operation—particularly important for indoor installations near living areas. The images below show actual production and testing areas.

Setup and Placement: What to Know Before You Fill the Tub

Space and Surface: The unit needs a level, dry area with at least 15 cm of clearance on all sides for airflow. The inflatable seated tub, once filled, exerts a footprint of roughly 80 × 80 cm and should sit on a flat, smooth surface—tile, sealed concrete, or a protective mat on hardwood. Avoid placing it directly on carpet without a waterproof barrier, as minor condensation can form on the tub exterior in humid conditions.
Power and Circuit Load: The 0.3 HP compressor draws a modest current—well within the capacity of a standard 10‑amp household circuit. It can share a circuit with other low‑draw appliances, though we recommend a dedicated outlet if you plan to run the chiller 24/7 alongside other equipment.
First Fill and Purge: On the initial setup, run the pump for five minutes with clean water only (no filter cartridge installed) to flush any residual manufacturing particles from the lines. Then insert the filter, fill the tub, and set the target temperature.

Energy Use and Estimated Running Costs

The 0.3 HP chiller uses approximately 0.22 kWh when the compressor is active. Under typical conditions—maintaining 10 °C in a 20 °C room—the compressor cycles on for roughly 6–8 hours per day. This translates to about 1.5–1.8 kWh daily, or 45–55 kWh per month. At an average electricity rate of €0.25/kWh, the monthly operating cost is approximately €11–€14.
For comparison, purchasing three 5 kg bags of ice per session, three times a week, costs roughly €60–€80 per month in most European cities. The chiller pays for itself within a year on ice savings alone, while eliminating the plastic waste from bagged ice and the time spent sourcing and transporting it.

How a Dedicated Chiller Compares to Alternatives

Metabolic & Physiological Wellness

Stimulates Brown Fat Activation: Regular ice baths activate brown adipose tissue (brown fat), which burns calories at a higher rate to generate body heat, ultimately boosting your overall metabolism.
Improves Lymphatic Drainage: The full‑body compression caused by cold water constriction forces lymphatic fluid through the lymph nodes, helping the body detoxify naturally.
Strengthens the Immune System: Studies show that regular cold exposure increases the production of white blood cells and antioxidants, making the body more resilient against common illnesses.
Optimizes Blood Circulation: When you exit the ice bath, your blood vessels dilate rapidly (vasodilation), rushing oxygen‑rich, nutrient‑dense blood back to your organs and extremities.

The main unit of the 0.3 HP ice bath machine, paired with a seated tub, undergoes rigorous real‑world testing prior to shipment. This ensures that every unit dispatched is of impeccable quality, allowing you to use it immediately upon arrival.

The 0.3 HP Ice Bath Chiller Unit supports OEM/ODM customisation. The standard workflow is outlined below.

The 0.3 HP Ice Bath Unit with Seated Tub includes an inflatable seated bathtub (white or black). Inflated, it gives you a comfortable upright position; deflated, it fits into a small carry bag for storage or travel.

Ice cubes can be added to speed up the initial cool‑down, and the chiller will then keep the water at your chosen temperature while the ice melts far more slowly than in a passive tub.

The Benefits of Ice Baths

Regular cold water immersion supports muscle recovery, reduces inflammation, and sharpens mental clarity through the release of endorphins and dopamine. It also helps lower core temperature after a long day, promoting deeper, more restorative sleep.

From Homeowners Who Use It Daily

“I wasn’t sure a cold plunge would fit in my small bathroom, but the 0.3 HP unit and inflatable tub take up very little room. I fill it twice a week, keep it at 10 °C, and it’s become the best way to wake up without coffee.”
— Sarah M., Apartment Owner, Berlin

“We bought this for my teenage son who plays football. It’s quiet enough that he can use it before school without waking the house, and the cooling is steady—no big temperature swings. Setup took less than an hour.”
— David P., Family Home, Austin

Frequently Asked Questions

Will this unit work in a small, enclosed room?
Yes. The 0.3 HP chiller emits very little heat and is quiet enough for a bedroom or study. Just make sure there is a few inches of clearance around the vents for proper airflow.

How long does it take to chill 300 litres of water?
From room temperature, expect about 2–4 hours to reach 5 °C. Dropping in a few bags of ice at the start can halve this time.

How often do I need to change the water?
With the built‑in filtration and regular filter changes (every 3–4 months), the water can stay clean for several weeks. Many users simply top up and only do a full change every 4–6 weeks.

Is the tub sturdy enough for daily use?
The inflatable seated tub is made of thick, durable PVC and designed for repeated use. It holds up well indoors and on sheltered balconies; just avoid sharp objects underneath it.
