Shop Hot Tub Products by What You Need

Not every hot tub care job starts with a brand name. Sometimes you need chlorine. Sometimes a cartridge needs replacing. Sometimes the water needs a little attention. Start with the type of product you’re looking for and narrow it down from there.

Hot Tub Chlorine & Bromine

Find chlorine and bromine products for regular hot tub sanitation, including options for different water-care routines and compatible systems. If you already use a FROG setup, you can also browse our dedicated FROG Hot Tub Products collection.

Hot Tub Water Balancing

Shop products for the basic chemistry jobs that come up during routine spa care, including pH and alkalinity products. Keeping these products on hand means you can address water balance without putting off your next maintenance session.

Hot Tub Shock & Oxidizers

Give your regular water-care routine an extra treatment with hot tub shock and oxidizing products. These are useful additions to a routine that involves more than simply maintaining your everyday sanitizer.

Mineral Cartridges & Sanitizing Systems

Find mineral cartridges and other products for compatible hot tub sanitizing systems. If your setup uses FROG products, shop replacement and system options without having to search through unrelated pool supplies.

Hot Tub Startup Kits & Treatments

Starting fresh or getting a hot tub back into a regular care routine? Browse startup kits and treatment products designed for specific stages of spa maintenance, rather than buying individual products one at a time.

Hot Tub Chemicals & Supplies FAQs

Most hot tub routines need products for sanitation and water balancing, with additional treatments used when specific maintenance needs come up. Your setup and routine determine which products you need.

Both are used for hot tub sanitation. The right choice depends on your existing system and water-care routine, so check your setup before switching products.

This collection includes mineral cartridges for compatible systems, including FROG options. If you know your system, start with the brand or system name to narrow your choices.

A startup kit can be a convenient place to begin, bringing together products for getting your hot tub into a regular care routine. You can then restock individual products as needed.
