View Full Version : Help! Countertops too thick for faucet connection

I have these beautiful ceramic vanities, but when I tried to install the faucet, only about 1/8" of thread stuck out beyond the lock nut. I'm assuming that is because the plywood, hardibacker, thinset, tile combination came out too thick. What do I do now?

Route out some of the plywood on the underside of the countertop.

Not an uncommon problem, TJ. :(

When making tile counters where deck-mount fixtures will be used, I drill out a plug large enough to accommodate the nut in the plywood with a hole saw where the fixtures will mount, then re-install the plug such that it can be removed from below after the mud and tile have been installed. Seldom are the fixtures long enough, in my experience, to work without such modification, but I've seen some that are.

In your case, I'd suggest you drill up from the bottom to take out a similar plug. Might be a large PITA, depending upon how close the fixtures are to the back of the counter and such, but...........

Maybe you can use a large self-feed bit and not hafta drill all the way through your plywood but just enough to get room for the nut.

My opinion; worth price charged.

Thanks guys. Will I risk cracking the tile?

...a large self-feed bit...

Are your talking about a Forstner bit?

Depending on the bit you use, you may have to glue a round block into the existing hole to give the bit something to center on.

Could use a Forstner bit, too, I suppose. I don't like to use mine for rough work, but a fella could be careful. :)

Here's what we used.

Very clever! I'll have to remember that.

For years I have cut out a section of wood on tub decks and C-tops just because of this problem. I take a jig saw and cut a section about 4x12, maybe 4x15 on tub decks and run the felt paper and lath over it. The mud and tile is plenty strong to support the faucet.

The plumbers normally appreciate it. :)

Here's how they worked out.

Nice, neat job. :clap1:

We had several to do, so it was worth the effort to make the jig. After that it was a piece of cake.

Most good quality faucets are available with a "thick" deck kit. That it basically is a longer nut that will fit through a standard faucet hole drilled in a countertop.

I guess this means that we are cheap. Still, they were Price Pfister and Moen. Not total crap.

I do the same jig saw thing,as Davy does and the faucet is tightened against the mud and the tile.
I've also forgotten and papered over the deck, and had to do the hole-saw thing and get crumbs in my eyes and face. (It helps me remember to not forget) :nod:
