The Casta Diva CD-K050MAX Smart Toilet combines powerful flushing performance with fully automated, touch-free convenience.

A built-in tank and MaP-certified 1000g flush ensure strong, reliable performance even under low water pressure or during power outages, keeping operation consistent when it matters most.

Enjoy true hands-free use with automatic lid opening and closing, foot sensor control, and automatic flushing. The system activates cleaning when you sit and completes flushing when you stand, making everyday use simple and hygienic.

The intelligent temperature system automatically adjusts seat and water warmth based on ambient conditions, delivering comfortable use throughout the year.

Multiple wash modes—including rear wash, feminine wash, and massage—provide a thorough and refreshing clean, supported by instant heating and a self-cleaning nozzle system.

Nano Bubble Cleaning Technology enhances cleaning performance through fine micro-bubble “bursting” action, improving stain removal efficiency while delivering a gentler, more comfortable wash experience.

UV nozzle sterilization technology automatically disinfects the spray nozzle after each use, ensuring continuous hygiene and reducing bacteria buildup for enhanced daily protection.

A quiet flush system, soft night light, and soft-close seat add comfort and convenience, especially during nighttime use.
