Market rises from USD 6.3 billion in 2026; 4.1% CAGR; sanitizers lead with 46.0% share

ROCKVILLE, Md., August 24, 2026 — The global pool and spa water treatment chemicals market is valued at USD 6.3 billion in 2026, is forecast to reach USD 9.4 billion by 2036, and is expected to expand at a 4.1% CAGR from 2026 to 2036, according to Fact.MR.

Digital water care reshapes chemical demand

The market is changing as traditional chemical sales combine with connected hardware and automated treatment systems. Fact.MR says service and maintenance models are shifting toward digital and performance-focused solutions that can reduce manual dosing needs. Manufacturers are also moving toward sensor-based water health systems, automated dosing, AI-powered analytics, and bio-based stabilizers. The report links this shift to growing interest in sustainable chemicals, reduced freshwater use, and lower chemical runoff.

North America benefits from strong residential pool construction, while Europe is seeing rising demand for sustainable chemicals. Fact.MR also identifies expanding commercial pool installations and growth in the spa and wellness industry as factors supporting demand through 2036.
