InSPAration 7463 Lavender Crystals for Spa and Hot Tubs

Bath bombs, oils and ordinary bath salts are made for a tub you drain after one use. In a hot tub they can foam, coat the filter and upset the water balance. Spa crystals are the version built for water that stays: InSPAration says this lavender blend contains no oils and will not clog filters or affect water chemistry.

Many people use a scent like this simply to mark the start of the soak and to cover the smell of sanitizer. It does not replace water care, and the listing does not publish a full ingredient list, so check the jar if your skin is sensitive.

Tip: Read your tub’s manual first – some makers, especially of inflatable tubs, advise against any additives – then add the crystals with the jets running.
