A bad smell from your hot tub almost always points to a specific chemical or biological problem – and the smell itself tells you which one. This guide walks through the most common hot tub odors, what each one means, and exactly how to fix it. No guessing required.
Most hot tubs need a full drain and refill every 3 to 4 months, but heavy use, foam, or stubborn cloudiness can push that timeline earlier. This post explains exactly how to tell when your water is done, how to stretch it a little longer, and what to do on refill day to start fresh.
