Can I drill a hole in my silgranit sink decking?

10 years ago

Have ordered a Diamond 210 Silgranit sink for my son's basement kitchen. It has one hole for the faucet. I found a great deal on a single hole faucet but it has a separate side sprayer.

I have two questions, Can I install the faucet without the sprayer? (I have questions in to supplier, but no answer yet, not clear from online specs) Or, could another hole be drilled into the decking of the drop in sink to accomodate the sprayer?

This is for a kitchen redo by insurance co. So, being installed by their construction/restoration co. My son is in the Army and doesn't have a lot of time to deal with/track down the guy doing restoration. (The flood happened in October 2012, and the kitchen now has flooring....sigh...)

Any help ASAP would be greatly appreciated. He is being posted out of town Sept 3 for 3 months, so he's trying to get as much done as possible beforehand. This is for a basement rental apartment, which he would like to actually rent out!

Yes you could drill another hole through that. You would use a regular hole saw.

What material is the countertops? If its laminate then easy, if its granite then you would need a different hole saw.

Sometimes they have the indents for the other holes on the underside of the sink.

can i drill faucet holes in acrylic tub

I'm far from an expert on this, but we are putting in a Kohler acrylic tub (Seaside -- about the only thing that fit our space), and they intend for you to cut holes in it to mount the tub filler. It even comes with a template for it. So it's certainly possible on at least some acrylic tubs. I don't know if there's anything different about the models you're looking at that would preclude it.

As a possible compromise that would let all be equally unhappy..... ;) The fabricator should purchase you a new sink. Then they should take the granite plug that they drilled out and epoxy it back in place. When the sink arrives they should drill a new hole further back to avoid the rim. It will NOT affect the structural integrity of the sink or faucet mounting. Epoxy is stronger than the granite is. You may see a very small "shadow" where the cut line is, but if they only missed by a bit, you really shouldn't even see that at all if the color match on the epoxy is good.

Can you drill extra holes into a one-hole sink?

What is the sink made of? Does the faucet have a trim plate that covers the holes? You can get through just about anything with the correct bits. Hole saws are even available with diamond if needed, but carbide does just about everything short of hard stone.

Our set-up: Faucet (integrated pull-out sprayer & water control), soap, air gap (required in CA- will be replacing with disposal air switch after inspection), and Instant-Hot at the end. I agree with the other suggestions - consider an instant-hot (we use it way more than I ever thought ... very handy) or the air switch (also very handy, easier than reaching over for the switch on the wall). Good luck!

Thanks guys for the responses. I have done some more checking, and it looks like there may be 'prearranged' knockout holes on the decking. Wish it was really clear on the description. I ordered it online from Home Depot, so perhaps my local store would know the answer.

Since I live 1000 miles away from my son, it is hard to try and organize this all for him. I can do the online searches and order online, but since I'm not dealing with his restoration company I just want to keep everything as simple as possible, and not leave room for error.

There will be laminate countertops going in. But the holes would be knocked out/drilled BEFORE installation. I just need to confirm that there are the knockout holes on this sink. Wouldn't it be great if HD and or Blanco made that crystal clear?

Yes, I believe there are knockouts on the underside, (drilled partially through) ...either way, Silgranite can be drilled, so you should be good to go.

There were many other knockouts on the underside of the single bowl Silgranite sink I got from Home Depot. They had stickers on them underneath explaing what they were and how to tap them out.

You just need a carbide hole saw and not go too fast.

Carbide hole saws are not easy to find, but I agree that's the ticket.

Sometimes the home centers in large cities carry them though.

Thanks for the help! I just spoke to Blanco Customer Service. There are four additional knockouts for accessories. However, it took half a day, lots of internet searching, a couple of phone calls, one to HD and one to Blanco to find this out. I wouldn't even have known to look for the additional knockouts if you GWebbers hadn't led me in that direction! When I kindly suggested to Blanco that they add this on to the description and make it clear to future potential customers that these knockouts are an option, well, she was let's say 'less than grateful'.."ma'am we have that information on our website". Well, perhaps not every customer wants to go back to the manufacturer's website to try and find that out (model numbers are different from what is stated on the HD site, and in fact she gave me the wrong model number at first...)

Anyhow, now I know, I thought I was doing Blanco a service letting them know it was not that clear, and it could be helpful to add that to the HD description..." Ma'am that is HD's description" Oh well, you can lead them to water....

Bought a Blanco Lexa SK sink. Had two pre drilled cutouts that are visible between the double sinks but none in the drain board to allow filtered drinking water dispenser installation. This sink does not have any additional pre drilled holes and Blanco customer service just advised me i void warranty if we drill one. DUD!

A 1 3/8" diamond dry bit on an angle grinder will drill your hole without ruining the sink in half a minute.
