Most faucets these days will accommodate a deck thickness of at least 1-1/4". But there are a few we run into that still do not. 3cm natural stone and man made "quartz" counter top products are so common I can't imagine why all the faucets haven't caught up by now.
Thank you for your question. This faucet has a 1 3/32" maximum deck thickness, which works with most standard counter tops. If the counter top is too thick, you can use the RP10612 extension kit, which will add 1" to the maximum thickness.
