How to Keep Water From SmellingUpdated 10 hours ago

If your cold plunge water develops an unpleasant odor, it is a sign that organic buildup, bacteria, or poor circulation is occurring. Smelly water is usually caused by missed maintenance steps and can be prevented with consistent care. This guide explains how to keep your water fresh and odor free.

1. Use the Recommended Maintenance Kit

The most effective way to prevent odors is to use the Arctic Warriors maintenance kit as directed. The kit is designed specifically for cold plunge systems and helps control bacteria and organic buildup without damaging internal components.

Using the recommended kit helps

• prevent bacterial growth
• reduce organic waste buildup
• keep water smelling clean
• extend filter life

2. Avoid Chlorine Use

Our cold plunge units are not designed for chlorine.

If chlorine is used

• it may damage internal components
• it may affect seals and fittings
• Arctic Warriors is not responsible for damage caused by chlorine

Chlorine can temporarily mask odors but often causes long term issues.

3. Approved Alternative: Food Grade Hydrogen Peroxide

If you choose not to use our maintenance kit, the only approved alternative we recommend is food grade hydrogen peroxide.

Food grade hydrogen peroxide helps

• oxidize organic contaminants
• eliminate odor causing bacteria
• support clear, fresh water

Only use food grade hydrogen peroxide and follow proper dosing guidelines.

4. Oxidize the Water Regularly

Odors are caused by sweat, body oils, and organic debris breaking down in the water.

Regular oxidation

• breaks down organic waste
• reduces bacteria growth
• keeps water smelling fresh

Oxidize weekly or more frequently if the tub is used often or shared by multiple users.

5. Keep Filters Clean and Flow Strong

Poor water flow allows bacteria to grow and causes odors to return quickly.

To maintain strong flow

• rinse the filter regularly
• deep clean or replace filters when needed
• make sure the filter is seated properly

Dirty or clogged filters are one of the most common causes of smelly water.

6. Shower Before Entering the Tub

Body oils, lotions, sweat, and dirt are the main contributors to odor buildup.

Encourage users to

• rinse off before plunging
• avoid lotions or oils before use

This simple habit significantly reduces odor issues.

7. Keep the Lid Closed When Not in Use

Leaving the tub uncovered allows debris and bacteria to enter the water.

Always

• keep the lid closed
• avoid leaving the tub exposed overnight
• store the tub in a clean environment

This helps maintain water freshness.

8. Change the Water When Needed

If odors persist despite proper maintenance, a full water change may be required.

Change the water if

• odor returns quickly after treatment
• water appears cloudy or dull
• the tub walls feel slippery
• the smell becomes strong or sour

Fresh water resets the system and restores cleanliness.

9. Adjust Maintenance Based on Usage

Increase care frequency if

• multiple people use the tub
• the tub is outdoors
• usage is daily
• weather is warm

High usage requires more frequent oxidation and filter care.
