“Smart toilets” are now within reach—relatively speaking, and a new entry in that category is the INAX ATS. Aimed at transforming a bath into a spa-like space, the ATS features a heater function, dual nozzles for personal cleansing, and a warm air-drying system. It also incorporates antibacterial technology to stop the spread of germs. Cost: $850 to $1,150. INAX USA. 424-237-1031. www.inax-usa.com.
