Step-by-Step Cold Plunge Tub Cleaning Guide

Step 1: Remove Big Stuff

First, take out anything floating. Use your hands or a net. Remove leaves, bugs, or dirt. This is the easiest step!

The filter keeps water clean. Look at it every day. Once a week, take it out. Rinse it with clean water. If it looks dirty, clean it with filter cleaner.

Step 3: Test the Water

Use test strips. Dip one in the water. It changes color. The colors tell you if water is safe. Follow the directions on the box.

What to check:

  • pH level (should be 7.2 to 7.8)
  • Sanitizer level
  • Alkalinity

Step 4: Wipe Down the Sides

Use your soft cloth. Add a little gentle soap. Wipe the inside of the tub. Go all around. Rinse with clean water. Dry with a towel.

Important: Never use harsh cleaners. They can hurt the tub. They can hurt your skin too.

Step 5: Clean Around the Tub

Don't forget the outside! Wipe the edges. Clean the steps. Keep the area around your tub tidy. This stops dirt from getting in the water.

Step 6: Check Everything Works

Turn on the pump. Does it sound normal? Check the temperature. Is it cold enough? Make sure everything is working right.

How to Keep Water Clean Between Cleanings

Cover Your Tub

Always use a cover when not using your tub. Covers keep out dirt, leaves, and bugs. They also keep the water cold. This saves energy!

Shower First

Take a quick shower before you plunge. This removes oils, dirt, and lotion. Clean bodies mean cleaner water.

Run the Filter

Keep your filter running. Most tubs need the filter on several hours each day. Check your tub's instructions.

Add Water Treatment

Some tubs need special water treatment. This could be chlorine or other sanitizers. Follow the directions carefully. Don't add too much!

Note: The Primal Health Cold Plunge has an easy filtration system. It does a lot of the work for you.
