Key Features

NanoBurst™ Waterline Sterilization

  • An advanced NanoBurst™ system continuously treats the internal water pathway, helping reduce odor-causing bacteria and biofilm buildup before water ever reaches the nozzle or bowl. This adds an extra layer of hygiene beyond standard UV nozzle cleaning — delivering cleaner water at every wash and every flush.

Powerful Flush Toilet

  • Achieve top-tier flushing performance with a MaP 1,000g rating. The built-in tank and pump system remove water-pressure limitations, delivering strong, consistent, and water-saving flushing power every time—ensuring a cleaner and more efficient bathroom experience.

Microgravity Bidet Seat

Foam Shield Protection

  • No Splashing, No Odor, No Sticking. This Japanese-inspired technology creates a thick foam layer the moment you sit down, preventing splash-back, trapping odors, and reducing residue. Enjoy a consistently cleaner and fresher bathroom environment.

Intelligent Temperature Adjustment

The Casta Diva CD-K030ULTRA-Smart Toilet is the very best purchase we made over 59 years of marriage

The Casta Diva CD-K030ULTRA-Smart Toilet is the very best purchase we made over 59 years of marriage. I love it. It works perfectly in all phases. The remote is so well designed. It not only works so well, but looks great in our newly designed bath.

This toilet exceeded my expectations. The bidet is amazing with adjustable pressure and temperature, and the heated seat is such a luxury, especially in the winter. I love the auto open and close lid and the automatic flush so everything feels hands free and clean. Installation was straightforward and it looks sleek and modern in our bathroom. It feels high end and makes such a difference in everyday comfort. Definitely worth the investment.

I honestly love this toilet way more than I expected. The auto open/close lid and foot-sensor flush feel super convenient, especially when your hands are full. The heated seat is cozy, the bidet is gentle but effective, and the foam dispenser really helps keep things clean and fresh. The flush is strong and reliable, and the blackout flush is a nice bonus for peace of mind. It looks sleek, works smoothly, and just makes everyday bathroom use feel easier and more comfortable. Definitely feels like a smart upgrade.

I absolutely love this toilet! The design is high-end and elegant. The hands-free operation, especially, is a standout feature: the smarter sensor automatically opens the lid when you approach and then auto-flushes and closes the lid as you walk away.
This product performs exactly as described. The flushing performance is powerful, clean and surprisingly quiet. For hygiene and comfort, the features are outstanding. The self-cleaning nozzle and warm water cleaning mode work wonderfully. Following the wash, the warm dryer is a great touch. We also appreciate the heated seat, which is perfect for cold seasons. This intelligent feature even automatically adjusts the temperature based on the room environment.
All my family members love this new toilet and we highly recommend it to everyone!
