How to Keep Your Plunge Water Clean in the Summer
Cold water plunging in summer offers a refreshing contrast to the heat, helping your body cool down, reduce inflammation, and maintain recovery routines. But with higher temperatures and more airborne contaminants like pollen, keeping your PortaPlunge clean can be more challenging during warmer months.
Here’s how to keep your plunge water fresh, clear, and inviting all summer long.
☀️ 1. Why Summer Maintenance Is Crucial
As temperatures rise, so does the likelihood of biological growth in your plunge. Warm conditions create an ideal environment for bacteria, algae, and mould—especially if your plunge is exposed to sunlight. Add in airborne debris like pollen and dust, and your plunge can quickly go from crystal clear to cloudy and uninviting.
Neglecting summer maintenance could lead to:
- Discoloured or smelly water
- Slippery internal surfaces
- Skin irritation or health risks
- Reduced performance from filters and pumps
The good news? With a few simple steps, summer plunging can be low-maintenance and ultra-refreshing.
🌳 2. Choose a Shady Spot in the Garden
Location matters. Position your PortaPlunge in a shady or partially shaded area to reduce heat exposure and minimise algae growth.
Sunlight not only warms your water but also accelerates the breakdown of organic matter. A shady spot helps:
- Maintain a cooler baseline water temperature
- Slow algae and bacterial growth
- Reduce the evaporation rate
- Lower the strain on your chiller or ice usage
If shade is limited, consider a canopy or lightweight cover when not in use.
🧹 3. Keep Pollen and Debris Out
Pollen levels soar in summer, particularly in gardens surrounded by trees, flowers, or grasses. Even a brief wind gust can introduce large amounts of pollen into your plunge.
Here’s how to combat it:
- Use a fitted lid or cover when not in use
- Skim the surface daily with a fine mesh net
- Rinse your body before plunging to minimise contaminants
- Place a mat beside the plunge to clean feet before entry
These small steps can significantly reduce the accumulation of debris and pollutants.
🔄 4. Should I Leave My Pump Running All the Time?
If you’re using a filtration or circulation pump, running it continuously during hot weather can help:
- Keep the water moving (discourages bacteria growth)
- Maintain a stable temperature
- Prevent debris from settling
However, consider using a timer or thermostat-based control to reduce energy use during cooler nights. Aim for 8–12 hours of filtration daily if not running it full time. Pumps also extend the life of natural water treatments by dispersing them evenly.
🧪 5. Chlorine vs. Non-Chlorine Water Treatments
When it comes to plunge pool sanitation, the key is balance. You want clean water—without compromising skin sensitivity or product lifespan.
Chlorine Pros:
- Highly effective at killing bacteria
- Inexpensive and easy to find
- Works quickly, even in hot weather
Cons:
- Strong odour
- Can dry or irritate skin
- May degrade materials over time
Non-Chlorine (Oxygen-based or Enzyme) Cleaners:
- Gentler on skin and eyes
- No harsh smell
- Better suited for natural and wellness-focused users
We recommend using a non-chlorine water treatment if plunging daily, particularly for those with sensitive skin. For infrequent use or multiple users (e.g. events), a low-dose chlorine treatment might be appropriate—just ensure you rinse thoroughly and test the water regularly.
💡 6. General Best Practices for Summer Plunge Use
Here’s a checklist to keep your PortaPlunge pristine in the warmer months:
✅ Cover when not in use – to prevent heat and debris buildup
✅ Circulate water – daily with a pump or chiller system
✅ Clean weekly – using mild natural cleaner and cloth
✅ Test water – pH and sanitiser levels at least once a week
✅ Drain and refresh – every 2–3 weeks in summer, or sooner if water becomes murky
✅ Keep body products out – avoid oils, lotions, or soaps before plunging
💭 Thoughts on Plunging in Summer
Plunging in summer can be a game-changer. While many people associate cold therapy with winter routines, hot weather plunges offer unique benefits:
- Helps regulate body heat after workouts or outdoor activity
- Reduces swelling and fatigue during long, active summer days
- Improves sleep quality when used in the evening
- Provides a powerful mental reset on hot, sluggish afternoons
The key is consistency—and a clean plunge you’ll want to use every day.
🧊 Final Thoughts
Your PortaPlunge is designed to be a low-maintenance, high-performance wellness tool—year-round. But in summer, a little extra care goes a long way. By following these best practices, you can enjoy cool, clean plunges even on the hottest days.
Whether it’s set up in your garden, at a festival, or by your sauna, keeping your plunge water clean ensures every dip is as fresh as the first.
