This Drake unit is specified for a 10-inch rough-in and pairs a 1.6 GPF Tornado Flush bowl with the C5 bidet seat in Cotton White. The two-piece construction means the tank and bowl are separate components, which is critical if your existing plumbing footprint matches this specific elongated profile.

In the product photo, verify the mounting bracket alignment between the tank and the bowl, as a gap here indicates a poor fit for your specific screw spacing. The C5 seat is pre-installed, so you are buying the entire assembly rather than just the seat, ensuring the bolt pattern is factory-matched to the Drake bowl.

The Legato model features a Tornado Flush system and includes the WASHLET C5 bidet seat with PREMIST and EWATER+ functions. It is designed as an elongated unit with a remote control included for operation. The listing highlights the integration of the bidet seat directly with the Legato bowl geometry.

Look at the photo to confirm the seat’s mounting rails align with the standard elongated bolt holes on the Legato rim. Since this is a complete toilet and seat package, the photo should show the seat already seated on the bowl, confirming that the C5's specific mounting hardware is compatible with the Legato's internal structure without requiring universal adapters.

This Aquia IV setup is a two-piece elongated toilet with a dual flush mechanism rated at 1.28 and 0.9 GPF. It is paired with the WASHLET C5 bidet seat in Cotton White and is designed for universal height installation. The dual flush lever is a distinct feature that differentiates it from the single-flush Drake model.

Check the photo for the dual flush handle position on the tank, as this affects the clearance for the bidet seat’s remote or controls if mounted nearby. The two-piece nature means you must ensure the tank-to-bowl seal is visible in the image, confirming that the C5 seat’s mounting points are not obstructed by the Aquia IV’s specific rim design.

The S500e is an electronic bidet toilet seat with a contemporary lid, designed for elongated bowls in Cotton White. It features EWATER+ technology and is labeled as Auto Flush Ready, indicating compatibility with automatic flush systems. This is a seat-only unit, not a full toilet assembly.

In the photo, identify the mounting bracket width and the shape of the lid, as the S500e has a distinct contemporary profile that may differ from the classic lid on other models. Ensure the photo shows the seat on an elongated bowl, as the S500e is not compatible with round bowls, and the mounting screw spacing must match your existing toilet's bolt holes.

This listing includes the WASHLET C5 electronic bidet toilet seat along with a Fluidmaster Better Than Wax toilet seal. The seat is designed for elongated bowls and features standard C5 functionality. The inclusion of the wax seal suggests this is often sold as a replacement kit for existing toilets.

Look for the Fluidmaster seal in the photo to confirm it is included, as this is a critical component for a proper tank-to-bowl connection. The seat itself should be shown without a toilet bowl, so you must verify that the mounting hardware in the image matches the specific screw spacing of your existing toilet, as the C5 is not a universal fit for all bolt patterns.

The S550e is an elongated electronic bidet seat in Sedona Brown with a classic lid design. It features EWATER+ bowl and wand cleaning, as well as auto open and close functionality. The Sedona Brown color is a specific finish that differs from the Cotton White options in other listings.

In the photo, check the color of the lid and the seat to ensure it matches your bathroom aesthetic, as Sedona Brown is a distinct shade. The auto open and close mechanism requires specific mounting clearance, so the photo should show the seat in a closed position to verify that the lid does not interfere with the toilet tank or surrounding fixtures.

The K300 is an elongated electronic bidet seat in Cotton White with instantaneous water heating. It includes PREMIST and EWATER+ wand cleaning features. This model is positioned as a mid-range option with specific heating technology that differs from the C5 and S500e models.

Look at the photo to identify the control panel location, as the K300’s interface may differ from the C5. The instantaneous water heating feature requires a specific water supply connection, so the photo should show the water inlet valve to ensure it is compatible with your existing plumbing setup and does not require additional adapters.

This is the WASHLET C5 electronic bidet toilet seat in Cotton White, designed for elongated bowls. It features PREMIST and EWATER+ wand cleaning. The model number SW3084#01 is specified, which is a standard C5 configuration. This is a seat-only unit intended for replacement on existing toilets.

In the photo, verify the mounting bracket and the shape of the seat to ensure it fits your specific toilet bowl. The C5 is not a universal fit, so the photo should clearly show the bolt holes and the mounting hardware to confirm compatibility with your existing toilet's screw spacing, as standard universal seats may not align with this specific model's requirements.
