A Cold Plunge Tub is an excellent tool for recovery and wellness, but like any water-based equipment, it requires regular cleaning and maintenance to ensure hygiene, efficiency, and long-lasting performance. Keeping your cold plunge tub clean prevents the growth of bacteria, algae, and mineral buildup that can affect both the water quality and your overall experience.
In this guide, we’ll explain how to clean a cold plunge tub step by step, how often you should clean it, and why a well-maintained tub—like those made by NEW—offers superior durability and hygiene for home and professional users alike.
Even if your cold plunge tub uses filters and circulation systems, water naturally accumulates contaminants over time. Sweat, body oils, dirt, and bacteria can thrive in cold water if not properly maintained.
| Reason | Description |
|---|---|
| Hygiene | Prevents bacteria, mold, and algae growth inside the tub and filtration system. |
| Performance | Keeps pumps, filters, and cooling units running efficiently. |
| Water Quality | Ensures the water remains clear, odor-free, and refreshing. |
| Longevity | Prevents material damage caused by mineral deposits or chemical imbalances. |
Cloudy or slimy water due to organic buildup.
Unpleasant smell from bacteria or stagnant water.
Stains or scaling on the tub surface caused by hard water.
Reduced cooling efficiency if the chiller or pump becomes clogged.
Maintaining a clean cold plunge tub keeps every session safe and rejuvenating—just as it should be.
Before you begin, prepare the following cleaning supplies:
| Category | Items |
|---|---|
| Basic Cleaning Tools | Soft sponge or cloth, soft-bristle brush, small net, and microfiber towel. |
| Cleaning Agents | Mild soap, white vinegar, or specialized tub cleaner (non-chlorine and non-abrasive). |
| Maintenance Supplies | Replacement filter (if applicable), pH test strips, and disinfectant tablets (optional). |
| Safety Items | Rubber gloves and bucket for draining water. |
Tip: Avoid using harsh chemicals like bleach or strong acids—they can damage the vinyl or PVC surface of inflatable cold plunge tubs.
The cleaning method depends on whether your cold plunge tub is in daily use or only occasionally. The following steps apply to most NEW cold plunge tubs, which feature a durable and waterproof PVC or vinyl body with easy-drain valves.
Before cleaning, make sure:
The cooling unit, pump, and filters are powered off.
Disconnect electrical components to avoid water contact.
Open the drainage valve or use a submersible pump to remove all water.
Tilt the tub slightly to let every drop flow out.
Dispose of the used water in an appropriate drain area.
Use clean water and a soft cloth to rinse off surface dirt.
Avoid spraying high-pressure water directly on seams or fittings to prevent damage.
Mix mild soap or vinegar with warm water in a bucket (1 part vinegar to 3 parts water).
Dip the sponge or cloth into the solution and gently scrub:
Inner walls
Bottom surface
Rim and seating area
For corners or seams, use a soft brush to remove residue.
Note: For stubborn stains, apply vinegar directly and let it sit for 5–10 minutes before wiping clean.
If your tub has a filter pump system:
Remove the filter cartridge.
Rinse it thoroughly under running water.
Soak it in a mild detergent solution if visibly dirty.
Allow it to dry before reinstalling.
Replace the filter every 2–4 weeks, depending on usage frequency.
After scrubbing, rinse the tub thoroughly with fresh water.
Use a microfiber towel to dry the interior completely.
Check for any leftover soap or residue—these can cause foaming when refilled.
If the tub is used by multiple people:
Add a small, non-chlorine disinfectant tablet to the next fill.
Maintain proper pH balance (between 7.2 and 7.8) for optimal comfort and safety.
Once clean and dry:
Close the drain valve tightly.
Refill with fresh water and reconnect the chiller or pump system.
Allow water to circulate for 10–15 minutes before your next plunge.
To maintain perfect hygiene and performance, follow this general cleaning schedule:
| Cleaning Task | Frequency | Purpose |
|---|---|---|
| Surface wipe-down | After every use | Removes sweat and residue. |
| Water change | Every 3–5 days (or weekly) | Keeps water clear and odor-free. |
| Filter cleaning/replacement | Weekly or bi-weekly | Maintains efficient circulation. |
| Deep cleaning and disinfection | Every 2–4 weeks | Removes invisible bacteria or algae. |
| Chiller system check | Monthly | Ensures smooth cooling and pumping function. |
If you plan not to use the cold plunge tub for several weeks:
Drain completely.
Clean and dry thoroughly.
Store in a cool, dry location, away from direct sunlight.
Deflate (if inflatable) and fold gently to avoid creases.
Even with regular cleaning, keeping water crystal-clear depends on proper usage habits.
Shower Before Use – Rinse off sweat, lotion, or body oil before plunging.
Use a Cover – Always close the insulated lid when not in use to prevent dust and debris.
Avoid Contaminants – Do not use soap, shampoo, or oils inside the tub.
Balance Water Chemistry – Use pH test strips and adjust as needed to maintain neutral levels.
Add a Filter System – For frequent users, an external filter pump keeps the water circulating and clean longer.
