Casta Diva Elongated One Piece Toilet - 17ft ADA Comfort Seat

In this review the Casta Diva elongated one piece toilet is evaluated for homeowners and remodelers who want a compact, modern toilet that balances performance and water savings. The single biggest reason to consider it is the combination of a powerful siphon jet flush with a dual-flush 1.1/1.6 GPF option, delivering strong waste removal while conserving water. The skirted one-piece design also keeps cleaning simple and reduces the chance of leaking between tank and bowl, making it a practical upgrade for busy bathrooms.

Key Features

• Skirted One-Piece Design: The integrated tank and bowl create a seamless surface that is easier to clean and reduces visible joints where grime can collect.
• Powerful Siphon Flush: A MAP rating of 1000 and a fully-glazed trapway provide consistent, quiet flushing with strong clog resistance.
• Dual-Flush Water Saving: Offers 1.1 GPF for liquids and 1.6 GPF for solids to help reduce water use while meeting WaterSense-oriented conservation goals.
• Comfort Height Seat: The 17 in ADA chair height and compact elongated bowl improve sitting comfort and accessibility without requiring extra footprint.
• Soft-Close & Quick Release Seat: The slow-close seat reduces slamming and the quick-release feature simplifies removal for deep cleaning.
• Complete Installation Kit: Includes the toilet, tank cover, pre-installed fill and flush valves, wax seal and hardware for standard 12 in rough-in installation.

Who It's For

The Casta Diva elongated toilet is well suited for homeowners updating a primary or guest bathroom who want a modern, low-maintenance fixture with good flushing performance and water efficiency. It works especially well in remodels where a 12 in rough-in and a higher comfort seating height are required.

Those who should look elsewhere include buyers needing a wall-hung or very low-profile rimless model, or projects requiring an unusual rough-in size. Commercial high-traffic installs may prefer a dedicated commercial-grade fixture rather than a residential one-piece toilet.

Pros & Cons

Pros

• Strong, quiet siphon jet flush with a high MAP rating that minimizes clogs.
• Dual-flush 1.1/1.6 GPF delivers real water savings for daily use.
• Integrated skirted design and elongated bowl make cleaning easier and improve aesthetics.
• Comfort height seating and soft-close seat add convenience and reduce noise.

Cons

• Compact footprint may still be larger than very small square models, so measure for tight spaces.
• Designed for a standard 12 in rough-in only, so not suitable for nonstandard rough-in locations.
