Intex PureSpa 4 Person Inflatable Hot Tub vs Intex PureSpa Saltwater System

These are not competing products. Product A is a four-person inflatable hot tub; Product B is the saltwater conversion kit that turns a PureSpa into a saltwater tub. Buy the PureSpa if you want a hot tub. Buy the saltwater kit only if you already own a compatible Intex PureSpa and want softer water and less chlorine handling. Owners of the PureSpa rate the bubble function and Fiber-Tech walls well but note the vinyl exterior and the cover wear over time; the salt cell is a small accessory with a titanium electrode that lasts years when kept clean.

• Choose the PureSpa if you want a complete four-person inflatable hot tub with a heater, bubble jets, hard water treatment and a thermal cover in one box.
• Choose the saltwater kit if you already own a compatible Intex PureSpa and want to switch it from chlorine tablets to a salt cell.
