Japanese firm unveils bathtub that promises full-body spa everyday

Japanese bathroom fixture manufacturer Science Co. has unveiled the "Human Washer in the Future" (Mirai Ningen Sentakuki), a fully automated, hands-free bathing system designed to transform showering into a spa-like experience. Displayed at the 2025 Osaka Expo, the device resembles a sleek, oversized bathtub with a canopy that encloses the user. Once inside, the user reclines as warm, soapy water fills the tub to chest level, while calming nature visuals and sounds play on a built-in display. The process, lasting a few minutes, is controlled by precision sensors that maintain optimal water temperature (around 100°F/38°C) and flow, with intelligent water recycling to promote sustainability.

Science Co. envisions future versions incorporating AI personalization for temperature, scent, and sound preferences. Inspired by a similar concept introduced by Sanyo Electric Co. at the
