Water Testing

Where can I get my hot tub water tested?

Hot tub water testing is free at every Hot Tubs of Tennessee showroom: Crossville, Franklin, Germantown, Knoxville, Lebanon and Murfreesboro. Bring a water sample from your spa, and we will test it and go over the results with you. No appointment needed, no purchase needed, and it does not matter where you bought your hot tub.

How Free Water Testing Works

Three steps, and the longest one is the drive.

1. Bring us a sample

Fill a small, clean container with water from your spa and bring it to any showroom during open hours.

2. We test it

Our team tests the sample and reads the results with you: sanitizer, pH, alkalinity, and what they mean for your water.

3. Leave with a plan

You walk out knowing what your spa needs and in what order. If it needs products, we carry them; if it just needs time or a drain, we will say so.

Why Test Hot Tub Water?

Balanced water feels better on your skin, protects your spa's heater and shell, and keeps sanitizer working the way it should. Unbalanced water is the root of most hot tub complaints: cloudiness, odor, itchy skin, and short equipment life.

How often should water be tested?

A quick home test about every ten days works for most spas on a salt system, plus a showroom test whenever something seems off or after a refill. Our water care guide covers the routine.

Want less testing altogether?

The FreshWater® Salt System keeps water clean for up to a year, and FreshWater® IQ tests the water for you every hour and tells you what it needs. Read about salt and FreshWater IQ.
