Horow offers 7 watersense certified toilets models in the lineup we track. This page is the Horow-specific cut of the broader EPA WaterSense Certified Toilets toilets category — same product class, narrowed to the Horow catalog only.

About Horow

Horow markets smart toilets directly to US consumers through Amazon, Wayfair, and its own storefront, undercutting TOTO Neorest and Kohler Numi by 50–70% on similar feature sets — auto open/close lid, heated seat, foot-sensor flush, integrated bidet wash with adjustable temperature, and tankless siphonic flush as low as 0.8 GPF. The HWMT-8733 and HR-T17Y models are the volume sellers. Quality and warranty consistency lags the Japanese brands, but the value proposition is real for shoppers under $1,500.

About EPA WaterSense Certified Toilets toilets

EPA WaterSense is the federal voluntary water-efficiency certification program.
