Should Hot Tubs Be Emptied Between Guests? Best Practices for Hot Tub Hygiene

When it comes to owning or managing a hot tub, one of the main concerns is maintaining cleanliness and hygiene, especially if the tub is used by multiple people or guests. A common question that arises is whether hot tubs should be emptied and refilled between guests. While the idea of emptying the tub may seem like the most thorough way to ensure cleanliness, it’s typically not necessary. However, following the right cleaning and maintenance practices is essential to keep the hot tub in optimal condition.

Hot Tub Hygiene: Understanding the Basics

Hot tubs are designed to circulate water through a filtration system, which works continuously to remove debris and contaminants. When hot tubs are used, the water may become slightly contaminated by oils, lotions, sweat, and other residues. To manage this, hot tubs rely on a combination of filtration and chemicals (like chlorine or bromine) to keep the water sanitized.

The water in a hot tub should be tested regularly for pH levels, sanitizer levels, and overall cleanliness. As long as these levels are maintained, it’s generally not necessary to empty the hot tub after each use. In fact, frequently draining and refilling the tub can put additional stress on the plumbing and the heating system and waste water.

When Should You Empty and Refill the Hot Tub?

While it’s not necessary to empty the hot tub between every guest, there are certain situations where draining and refilling the tub is a good idea:

  1. After a Large Group of Guests
    If your hot tub is used by a large group or for a special event, it may accumulate more body oils, lotions, and dirt than usual. In such cases, it may be a good idea to drain the tub and clean it thoroughly to maintain water quality.
  2. Every 3 to 4 Months
    Even with regular filtration and chemical treatments, it’s recommended to drain and refill your hot tub every 3 to 4 months. This ensures that the water doesn’t become overly saturated with chemicals and provides a fresh start.
  3. If the Water Appears Cloudy or Smelly
    Cloudy or foul-smelling water is a clear sign that the hot tub needs attention. If regular water treatment isn’t working, it may be time to drain the tub, clean the surfaces, and refill it with fresh water.

Maintaining Hygiene Between Guests

Rather than emptying the hot tub, there are several ways to maintain hygiene between guest uses:

  1. Use Hot Tub Sanitizers
    Sanitizers like chlorine, bromine, or non-chlorine alternatives are key to maintaining clean water. Make sure to add sanitizer regularly, particularly after each use. You can also use a floating sanitizer dispenser to keep the levels consistent.
  2. Ensure Proper Filtration
    Your hot tub’s filtration system is responsible for removing debris and contaminants. It’s crucial to keep the filter clean and replace it regularly. Most hot tubs will run a filtration cycle multiple times a day to ensure the water remains clean and clear.
  3. Shower Before Entering
    Encourage guests to shower before entering the hot tub to remove oils, lotions, dirt, and sweat. This reduces the amount of debris that enters the water and helps maintain cleaner water for longer.
  4. Use a Hot Tub Cover
    When the hot tub is not in use, keep it covered. This prevents debris like leaves, insects, and dirt from contaminating the water. It also helps maintain the temperature and reduces the amount of time the heater needs to run.

The Role of Regular Maintenance

Regular maintenance is crucial to ensuring your hot tub remains clean and safe, especially when used by multiple guests. In addition to checking chemical levels and cleaning the filter, you should also inspect the jets, plumbing, and the shell for signs of wear. Keeping the hot tub in good working order will make it more enjoyable and safe for guests.

Conclusion

In summary, while it’s not necessary to empty and refill the hot tub between each guest, maintaining proper hygiene practices is essential. Regularly testing and balancing the water, using appropriate sanitizers, cleaning the filter, and encouraging guests to shower before use can all contribute to keeping the hot tub clean. By following these best practices, you can ensure that your hot tub remains a safe, relaxing, and hygienic place for everyone.
