Foam in a hot tub can be caused by dirt, skincare products, or a chemical imbalance. Use a hot tub test kit to figure out which problem is causing your hot tub foam! Then, you can follow the below instructions to solve the hot tub foam problem.
Getting into the hot tub should be a relaxing experience, like taking a bath and getting a massage at the same time. One of the ways in which baths and hot tubs differ is the addition of soap to create foam and bubbles. Foam can add a touch of luxury to a bath, but in a hot tub foam indicates that the water has become dirty and needs changing. Today, we're going to look at what causes foam in a hot tub, so that you can learn how to enjoy a crystal-clear hot tub for longer.
What are the main causes of foam in a hot tub?
When it comes to hot tub foam, there are a few main causes that you should watch out for. Hot tub foam usually occurs when a hot tub has been used by multiple people for a prolonged period of time.
There may be foam in your hot tub if you recently had a party. Unless you took the time to ask every guest to shower before getting in the hot tub, then there are probably some additional substances in your hot tub water now. Here are a few things that can cause hot tub foam:
- Body lotion
- Skincare products
- Fake tan
- Makeup
- Excess laundry detergent
- Deodorant
- Hair products
- Body oils
To prevent a build-up of foam in your hot tub, it really is important that everyone using the hot tub has showered and removed as many of the above-mentioned surfactants as possible. It only takes a few minutes to rinse yourself in the shower, and it will make a difference to the quality and longevity of your hot tub water.
Are these the only causes of hot tub foam?
While personal products are one of the main causes of hot tub foam, they're not the ONLY cause. Another reason that foam builds up in hot tub water is if there's a chemical imbalance. That's why it's so important that you check and regulate the chemicals in your water on a regular basis.
Water with a low calcium content is known for creating excess foam. The low calcium content reduces the surface tension of the water in the same way that a build-up of soap, lotions, and dirt will.
How do you treat foamy hot tub water?
If you've got a problem with foam in your own hot tub, it can be fixed. But first, you'll need to diagnose the cause of the problem. If you're noticing foam in your hot tub for no apparent reason, then it's time to do a hot tub test. These are simple strips that will tell you important information about your hot tub water.

Hot tub foam caused by dirt
If the test shows that the water balance is fine, then it's probably a build-up of dirt and residue that's causing the foamy water. In this scenario, you'll need to drain the old water from your hot tub and replace it completely. This may seem like an inconvenience, but it's important you change the water in your hot tub on a semi-regular basis if you want to keep your spa running properly.
