Why does my Cold Plunge smell bad?

If your Cold Plunge has an unpleasant odor, it often indicates the growth of bacteria or algae in the water. Contaminants such as body oils, sweat, or debris can contribute to this issue, especially if the water hasn’t been changed regularly.

Additionally, poor circulation can exacerbate the smell, as stagnant water is more prone to developing odors. Regular maintenance, including cleaning and water changes, is crucial to prevent this problem.

For instance, if you've recently used the tub with several people, you may notice a stronger odor if the water isn’t changed promptly afterward. A good practice is to add a pool sanitizer or shock treatment to the water when you notice a smell to help kill off the bacteria.

A pro tip is to establish a routine cleaning and water-changing schedule to keep smells at bay.

However, if the odor persists despite regular maintenance, it may indicate deeper plumbing issues that require professional inspection.
