CASTA DIVA CD-T005 One-Piece Elongated Toilet, Dual Flush, 17-Inch Seat

At 27.17 inches deep, 14.37 inches wide, and 25.39 inches high, the CASTA DIVA CD-T005 is a compact, floor-mounted toilet with an elongated bowl and a 17-inch comfort-height seat.

Its ceramic, one-piece construction brings the tank and bowl together in a smooth, skirted form. The integrated design gives the bathroom a clean, streamlined look and makes the exterior easier to wipe down.

Want a choice of flush volume without giving up a chair-height seat? This model pairs dual-flush controls with a soft-close, quick-release seat for practical everyday use.

What matters most

The dual-flush system uses 1.1 GPF for liquids and 1.6 GPF for solids, letting you select the flush suited to the task. A siphon flush and fully glazed trapway are designed to support effective waste movement, while the slow-close seat helps prevent a sudden slam. Its elongated bowl and 17-inch seat height bring familiar chair-height positioning to a compact one-piece footprint.

The tank and bowl are integrated rather than joined as separate pieces, creating fewer exterior seams to clean. Customers also highlight the toilet’s streamlined appearance, easy-to-clean one-piece design, comfortable seat height, and dual-flush operation. These are useful priorities when choosing a fixture for a bathroom refresh or a new installation.

Getting the most from it

This toilet is designed for a standard 12-inch rough-in and floor-mounted installation. The listed dimensions can help you plan how the fixture will sit in the room, measure the available area and confirm the rough-in before installation. The installation description lists a mounting kit and hardware, along with a wax seal, preinstalled fill and flush valves, and an elongated slow-close seat with lid.

For a straightforward bathroom setup, the integrated tank and bowl keep the exterior profile visually continuous. The quick-release seat also makes it easier to access the area around the seat during routine cleaning. The white ceramic finish and elongated bowl suit a range of bathroom layouts where a clean, coordinated look matters.

Best use cases

The CD-T005 suits bathrooms where a one-piece design, elongated bowl, and chair-height seat are priorities. Its compact listed dimensions make it relevant for planning a smaller bathroom, while the dual-flush option gives households a choice between the two specified flush volumes. It can also work well in a remodel where a 12-inch rough-in and floor-mounted toilet match the planned installation.

Compared with choosing a separate tank-and-bowl toilet, this integrated style offers a continuous exterior that is simpler to wipe around. That makes it a practical direction for shoppers who value a streamlined look and easier exterior cleaning. The seat’s slow-close action adds a quieter finish to everyday bathroom use.

What to clarify

What rough-in does the toilet use? It is designed for a 12-inch rough-in, so confirm that measurement at the installation location before fitting the toilet.

How much water does each flush use? The dual-flush settings are 1.1 GPF for liquids and 1.6 GPF for solids.

What are the toilet’s overall dimensions? It measures 27.17 inches deep, 14.37 inches wide, and 25.39 inches high. Use these dimensions to plan the available floor and surrounding clearance.

When it makes sense

Choose the CASTA DIVA CD-T005 when you want an elongated, chair-height toilet with a compact listed footprint, dual-flush options, and an integrated ceramic design. Its 12-inch rough-in, soft-close quick-release seat, and smooth one-piece exterior make it a considered fit for bathroom updates that prioritize convenient everyday use and a clean, streamlined appearance.
