Smart toilets are toilets with integrated electronic features — heated seats, bidet wash, auto-flush via motion sensor, auto-open/close lids, deodorizer fans, and (in the premium tier) UV sanitization and air drying. The US market is dominated by three brands: TOTO Neorest (the original luxury smart toilet, $4,000–$8,000), Kohler Karing ($5,500–$7,800), and value-tier offerings from Woodbridge ($899–$1,499) and Swiss Madison ($699–$1,299).
The decision between premium and value-tier smart toilets isn't just aesthetic. Premium models (TOTO Neorest 750H, Kohler Karing) include features like CeFiONtect ceramic glaze, ACTILIGHT UV sanitization, and PreMist (sprays bowl with water before use to prevent waste sticking) that meaningfully change daily use. Value-tier models cover the basics (heated seat, bidet, auto-flush) at one-third the price but skip the long-term durability features.
Power requirement: every smart toilet needs a GFCI-protected 120V outlet within 4 feet of the toilet. New bathroom construction handles this easily; retrofit installation may require an electrician ($200–$400) to add the outlet. Factor that into the total project cost.
Our top pick across price tiers is the TOTO Neorest 700H ($3,999–$4,999) — premium build, integrated Washlet, comfort height, and the proven 20-year reliability track record of TOTO's smart toilet line. For value-tier, the Woodbridge BTS-77 ($899–$1,099) delivers the full smart toilet experience for under $1,000.
