4 Reasons Why Your Hot Tub May Be Foamy
When you imagine relaxing in your hot tub, you imagine bubbles, not foam. These smaller, white bubbles may be unsightly and concerning if you find them in your spa. What is causing your hot tub to foam, and how can you remove the foam or prevent it from happening again?
1. Personal Care Products
There’s a reason that public pools and hot tubs ask people to rinse off before they step into the pool. When they do, they can leave behind residue from their personal care products, which may cause foaming. If this is your problem, you might also find that the hot tub is cloudy as well as foamy.
Potential sources of this foaming include:
- Body oils and sweat
- Body lotions
- Body soap residues
- Laundry soap residue
- Perfumes and colognes
- Shampoo and conditioner
If you suspect your issue is the things you’re bringing into the tub with you, you can always rinse yourself off before you head into the spa. Ask your guests to do the same.
2. Spilled Drinks
A spilled drink can create issues in your hot tub, and because they are already wet, sometimes people don’t realize they’ve spilled in the water. Spilled drinks can become surfactants that reduce surface tension and make foaming much more prominent. The solution is to partly drain the tub to reduce the amount of spilled drink in there. If there have been large or repeated spills, you may want to drain the hot tub altogether and replace it with fresh water.

3. Too Much Overall Chemicals
It’s not using too many different chemicals that may lead to foaming. Instead, it’s using too much volume of chemicals overall, or you’re using cheap chemicals with poor quality fillers. This is especially likely to be the problem if your hot tub foams after you shock it.
The solution is not to reduce your chemical usage necessarily. Go over hot tub chemical treatments and testing with the professionals, as you may find you’re using chemicals perfectly appropriately and it’s more likely that you need to upgrade to higher-quality chemicals.
4. Mineral Levels
Low mineral levels in the water can also encourage foam in hot water. While we usually spend time trying to soften our water, hard water is better for hot tubs, at least when it comes to foaming. If you’re using a water softener on your hot tub, turn it off, and you’ll likely find that the foam is reduced. The calcium and other minerals in the water help to maintain surface tension, so bubbling is limited.
