Thanks for reachighn out tous. Yes, our kitchen deck plates measure 10" and could also be used in bathrooms as it is a matter of preference.
This has a gasket built into the bottom of the deck plate. Faucets have a gasket that will seal to the top of the hole as well.
HI Alan, Thanks for reaching out to us. Yes, our DP01 10 inch deck plate would pair perfectly with our KPF-1610 Bolden. Hope this helps. Please feel free to reach out to us at 800-775-0703 or via email at firstname.lastname@example.org with any additional questions. Thank you for reaching out.
No retaining hardware came with mine. Any faucet will move if the nut under the sink is not tight enough. Retighten.
