What is the Gecko WaterLab Probe?
The Gecko WaterLab Probe is a smart water-monitoring sensor designed to work seamlessly with Gecko Alliance control systems. It continuously tests your spa water for key chemical levels — including pH, ORP (sanitizer), and temperature — and transmits readings directly to your Gecko WiFi-enabled controller or app. No more manual testing. No more guesswork.
Whether you're replacing a faulty probe or upgrading your spa's water management system, this is the part you need.
Why Replace Your Gecko WaterLab Probe?
Accurate water chemistry, automatically
The WaterLab Probe monitors your spa's water in real time, alerting you when chemical levels fall outside the safe range. A worn or damaged probe means inaccurate readings — and that can lead to skin irritation, equipment damage, or worse.
Designed for Gecko systems
This is a genuine Gecko replacement part, engineered to integrate with Gecko Alliance controllers and WiFi accessories without any compatibility issues.
Extend the life of your spa
Keeping your water chemistry in balance protects your pumps, heater, and shell from premature wear. A functioning probe is one of the most cost-effective ways to protect your investment.

Frequently Asked Questions
How do I know if my Gecko WaterLab Probe needs replacing?
Common signs of a failing probe include inaccurate water chemistry readings, a probe that fails to connect to your Gecko app, error codes on your controller display, or visible physical damage to the probe body. If you're unsure, send us a photo and we can help diagnose the issue.
Do I need the Gecko WiFi module to use this probe?
Yes. The WaterLab Probe communicates with your spa's control system via the Gecko IN.LINK WiFi module. If you don't already have this installed, it can be ordered separately. Contact us and we'll help you put together the right combination of parts.
What's the difference between the U, C, E, and A suffix versions?
Western Tub and Pool is an international e-retailer, and we source parts from warehouses across multiple regions. To help you identify where your part ships from, we've added suffixes to part numbers:
- U = United States
- C = Canada
- E = Europe
- A = Asia
Some parts may be available from more than one regional warehouse. Availability may affect pricing and shipping times. If you have a specific part number already, check the suffix or contact us and we'll confirm which version is right for you.
Can I install the Gecko WaterLab Probe myself?
Many spa owners with basic DIY experience are able to replace the probe themselves. We recommend consulting your spa's service manual or reaching out to us if you have any doubts. Incorrect installation can affect water readings and potentially void warranties.
How long will shipping take?
Shipping times vary depending on your location and the regional warehouse fulfilling your order. We'll do our best to provide an estimated delivery window when you place your order. For urgent orders, give us a call at 1-855-248-0777 and we'll find the fastest available option.
I don't know my part number — can you still help me?
Absolutely. Send us an email with a photo of your existing probe, your spa's make and model, and the serial number from the equipment compartment. Our team will identify the correct part for you.
