History of Smart Toilets
Smart toilets trace roots to 17th-century French bidets, but Japanese innovation in the 1980s with TOTO’s Washlet introduced electronic features like heated seats and bidet sprays, achieving over 80% adoption in Japan by 2000. Amazon smart toilets emerged in the 2010s as affordable Chinese alternatives, flooding the market during the 2020 pandemic with models emphasizing cost over premium tech. Japanese brands focus on precision, such as 43-degree spray angles for optimal cleansing, while Amazon options prioritize accessibility with basic automation. By 2025, Japanese toilets lead in innovation, incorporating health sensors, whereas Amazon variants appeal to entry-level users.
