2. Installation Guide
Follow these steps for proper installation of your CASTA DIVA CD-BT02 bidet seat.
2.1 Pre-Installation Checks
- Ensure your toilet is an elongated model. The bidet seat dimensions are 19.68" L x 14.56" W x 2.44" T.
- Confirm access to the toilet's water supply valve.

2.2 Step-by-Step Installation
- Remove Existing Toilet Seat: Lift the hinge covers and use a screwdriver to remove the bolts holding the old seat in place. Remove the old seat.
- Install Mounting Plate: Insert the rubber expansion nuts into the toilet bowl holes. Place the mounting plate over the holes and secure it with the provided screws. Tighten the screws to ensure the plate is firm.
- Attach Bidet Seat: Slide the bidet seat onto the mounting plate until it clicks into place.
- Connect Water Supply: Turn off the water supply to your toilet. Flush the toilet to drain the tank. Disconnect the existing water supply hose from the toilet tank. Install the T-valve (G15/16 for shutoff valve, G15/16 for toilet inlet valve, G1/2 for bidet hose) to the toilet fill valve. Connect the bidet hose from the T-valve to the bidet seat's water inlet. Reconnect the toilet's water supply hose to the T-valve.
