Hi HomeDepotCustomer,
Thank you for taking the time to share your experience with us. Yes, that is correct; the Ladera Bar & Prep faucet is designed to be installed in a single hole and does not have an optional deck plate. As the original purchaser, your Pfister faucet is backed by a lifetime warranty for as long as you own your home. If there is ever anything we can do to help, please know that our Support Team is here and happy to assist with any installation, troubleshooting, or warranty needs you may have by calling us at 1-800-732-8238.
Thank you,
Pfister
