Most important from
9 reviews
The Kohler K-77795-2MB Eir One-piece Elongated Smart Toilet offers a range of modern features designed to enhance comfort and hygiene. Its bidet functionality is advanced, with a stainless steel wand that provides adjustable spray shape, position, water pressure, temperature, and even pulsate and oscillate functions. The elongated bowl and Comfort Height feature make it easy and comfortable to use, especially for most adults.
This smart toilet also includes an automatic lid and flush, enhancing convenience and reducing the need for manual handling. The integrated deodorization system and self-cleaning functionality, which uses UV light and electrolyzed water, help maintain hygiene with minimal effort. The warm-air drying system and dual flush options (0.8 or 1.0 gpf) contribute to water conservation and energy efficiency.
Despite these impressive features, the product is relatively heavy at 110.6 pounds, which might complicate the installation process. This smart toilet is most suited for those looking for a high-end, feature-rich option that prioritizes comfort and advanced cleansing technology.

Casta Diva Smart Toilet with Bidet Built in, Auto Open Close, Foot Sensor, 1000 MaP Auto Flushing, ADA Comfort Height, Artistic Lighting, Smart Heated Seat, Foam Dispenser, Tank Built in (CD-U010Max)
Most important from
69 reviews
The Casta Diva Smart Toilet CD-U010Max brings a luxurious and tech-savvy experience to your bathroom. It checks many boxes for a smart toilet: the bidet function offers multiple warm water cleaning modes including rear, front, and massage washes with a self-cleaning nozzle to keep things hygienic. The heated seat adapts to the room temperature automatically, so you get comfort year-round, though you need to switch this feature on manually. Automatic lid and flush operations work smoothly through motion and foot sensors, allowing a hands-free experience that’s especially helpful for hygiene and convenience. It also features a powerful 1000 MaP siphon flush that handles waste efficiently while saving water.
Unique to this model is a foam protection system that reduces splashes and odors, which is a nice touch for freshness. The smart electrolyzed water cleaning system helps keep the bowl clean without harsh chemicals, adding to the self-cleaning appeal. The toilet includes a remote control and soft LED lighting that creates a calming atmosphere. It’s sturdy and well-built with ceramic material and ADA-comfort height, making it accessible and durable.
The system depends on electricity for many features, and while it has a blackout flush, other smart functions won’t work in a power outage. Also, the foam system needs liquid soap preparation, which might require some maintenance. At about 97 pounds, installation may need professional help. This smart toilet is a great choice if you want a modern, comfortable, and hygienic bathroom upgrade with advanced cleaning and comfort features, but keep in mind the slight learning curve to activate and maintain all its smart functions.

Casta Diva Smart Toilet with Bidet Built in, Auto Open/Close Lid,1000g MaP Flush, Heated Seat & Foam Dispenser, Foot Sensor Auto Flush, Blackout Flush, Bidet Toilet with Tank Built in (CD-K030PRO)
Most important from
128 reviews
The Casta Diva Smart Toilet CD-K030PRO stands out with its powerful 1000g MaP flush, which ensures thorough cleaning without depending on strong water pressure, making it reliable in most home setups. Its bidet functions shine with multiple warm water modes including rear, front, and oscillating sprays, plus an instant warm water supply, providing a comfortable and customizable cleaning experience. The heated seat with five temperature settings adapts automatically to room temperature, enhancing comfort year-round, though this feature needs to be manually activated when first used.
Convenience is a strong point: the toilet has an automatic lid that opens and closes as you approach or leave, plus hands-free foot sensor flushing and a quiet flush at 45dB, which is gentle on light sleepers. A unique foam shield helps keep the bowl clean and odor-free without splashing, which is a thoughtful touch for hygiene. Additional luxury touches include a warm air dryer, auto deodorizer, night light, and a user-friendly remote control for easy adjustments.
Installation is floor-mounted ceramic with all necessary kits included, but the toilet is relatively heavy at nearly 96 pounds, which might require professional installation. The product is energy efficient with its smart temperature controls and self-cleaning nozzle, though the need to mix dish soap for the foam shield might be a slight inconvenience for some users. This smart toilet suits those seeking advanced hygiene, comfort, and hands-free features in a modern bathroom, with a recommendation that beginners carefully follow setup instructions to use all functions effectively.
