We bought a widespread faucet for our new bathroom vanity - unfortunately, the max deck thickness is a 1-5/8", and the countertop is 2" thick. I called the retailer but there's no deck extension kit for this faucet. Is there a deck extension kit from another manufacturer that would work here? The faucet has 1" shanks with straight threading. The spout has a valve that screws on to the end of the shank, so the extension would need to have a hose-style compression fitting on the end to get a sealed connection. The drilled holes in the deck are 1-1/8", so the extension would need to fit inside that.

Any ideas?

(Other than "buy a better brand of faucet with a deck extension kit")

The kits would be "brand specific" so unless that faucet was made by a major manufacturer and rebranded, you are probably out of luck, unless you can "recess" the mounting.

The countertop is marble, so I probably could "recess" the mounting by countersinking the underside of the faucet hole with my dremel. But I'd have to notch at least 1/2" out, and the countertop is already installed so it'd be awkward. And I'd have to do that for 3 separate holes. That doesn't sound like much fun.

I would guess that the marble has plywood under it.
You will need to use a hole saw and make larger holes in the wood. You can place a 2x4 over the top, and drill into that for the pilot. The marble setter should have cut the plywood out for the faucet first. But they don't always. It's a nasty job cutting the wood out after the fact.

Hey, wait a minute.

This is awkward, but...
