What hole size for installing a sink faucet?

[Aaron Fude]

Hi,

My plumber is coming tomorrow morning and he is expecting me to have prepaired the vanity top for a faucet installation. (It was a custom top and doesn't have any holes in it for the plumbing.)

I have the faucet, and I drilled a 3/4" hole becuase that slightly exceeded the diameter of the threads on the faucet. But then I realized that the plumbing part of the faucet has a wider part. Anyway, it's hard to explain, but the bottom line is that I don't know what size holes to drill and how to determine it.

The included instructions assume that the holes are already there.

Is there such a thing as a standard hole size for the faucet's plumbing?

My faucet is this:

Thanks!

If the included instructions do not include hole size measurements, you bought a product from a manufacturer who was just kidding about being in the faucet business. Made in China, maybe? The manufacturer's web site has links to PDF files for installation & measurement. The latter file is one blank page. The former link leads to a broken web page containing nothing.

Here's the web page, in case you want to be nauseated by the non-existent help they're providing:

You got boned. Return the thing and reschedule the plumber. A manufacturer like that doesn't deserve anyone's money. Get yourself a Moen faucet. Here's what a spec sheet is supposed to look like:

He may have got boned out of some dumass instructions, but HELL all you have to do is look a the bottom of the dam thing , measure and drill and hone away. It's not rocket science.

Perhaps, but the manufacturer still doesn't deserve his business.

Hi,

Thanks for the responses. Which size should I measure if there are two different diameters and I'm not quite sure how the faucet "sits".

Thanks,

Aaron

Use a piece of corrugated cardboard "surrogate countertop" to experiment. Got calipers for measuring outside diameter of the parts that protrude through the counter? Like this:

If not, use tweezers, compass, scissors or BBQ tongs as makeshift measuring devices.

Big enough to stick it through, small enough so nut/washer can secure it and so the upper flange (base) will cover it.

You re going to need 3 holes. Let the plumber drill them If you 'slip up', you 'll risk ruining the whole thing
