To replace a two-handle faucet with a spray nozzle to a one-handle faucet with a soap dispenser, you'll need to follow these general steps:

Shut off the water supply to the faucet by turning off the water valves under the sink. Disconnect the supply lines from the existing faucet. Remove the nuts or screws securing the faucet to the sink. Lift the old faucet out and clean the sink surface. Take the new one-handle faucet and soap dispenser assembly and position it in the sink. Attach the faucet to the sink using the provided nuts or screws. Connect the supply lines to the appropriate valves on the new faucet. Install the soap dispenser according to the manufacturer's instructions. Turn on the water supply and check for any leaks. Test the faucet and soap dispenser to ensure they are working properly. Please note that the specific steps may vary depending on the brand and model of the faucets involved, so it's always a good idea to consult the installation instructions provided by the manufacturer.
