The kitchen is the heart of the house. And countertops are probably the number one item that adds to the beauty and comfort of your kitchen. Since the sink is usually a large unit, it’s important that it be installed to properly fit in the countertop. The installer is an expert and works hard at his/her trade.

Do Countertop Installers Install The Sink Too

Countertop installers do install the sink but they do not usually connect the plumbing. The sink needs to correspond with the countertops for continuity. The countertop installer will cut the holes for the sink, faucet, and soap dispenser, as well as install the sink.

A countertop installer not only has the skill but also understands the aesthetic and physical properties of countertops, sinks, and base cabinetry. This involves construction, design, and craft. And your countertop installer should be able to take care of it all – except the plumbing.

If you have an undermount or drop-in sink there are different measures taken into consideration.

For an undermount sink the installer will attach the sink using silicone and sink clamps.

For a drop-in sink the installer will cut the hole for the sink if not already cut and set the sink in place. They will also use silicone to connect the sink to the countertop and use sink clips underneath to firmly attach the sink.

Steps to Installing Your Sink Into Your Countertop

If, for instance, you choose an undermount kitchen sink with granite countertops:

  • It will be mounted under the stone slab.
  • Clips will be used to keep it in place.
  • At that point, your installer will add silicone for a good seal.
  • Once the sink is installed, it will need to cure for about twelve hours.
  • Now a plumber can install the plumbing and faucet.

The countertop installer doesn’t do the plumbing. And from a skill standpoint, you don’t want the plumber installing the sink.

Note: Make sure you have all your plumbing disconnected prior to the sink installation.

What to Expect During Installation

Countertop and sink installation is a construction process. It will be a little difficult to live around for a while. There is bound to be:

  • Dust
  • Noise
  • Disruption to the household

It will take several hours to accomplish the installation, and that doesn’t include installing the backsplash. There usually will be some onsite cutting to customize your countertop sizes, so you’ll want to take some precautions against the dust that will be everywhere. Precautions to take include:

  • Cover artwork
  • Cover furniture
  • Cover vents with plastic
  • Cover doorways with plastic
  • Empty cabinets
  • Remove anything breakable

A professional countertop installer will probably put up some plastic for you. They will also clean up the mess. But you’ll still need to cover your treasured items. And the dust is so fine that you’ll find despite all the precautions, some of the particles of dust will be around.

Remember, large slabs of stone or whatever material you choose will be carried into your home. Keep all children and pets away. This is a construction site for a few hours, and there are dangers associated with construction.

You also want to clear a path from the door to your kitchen. Make sure you take artwork off the walls and store it in a safe place. And don’t forget the hallway walls. Anything hanging on the walls could get bumped as the installers carry the countertops into your home. If your bathroom is receiving a new sink/countertop, follow the same procedure.

What Type of Prep is Needed for New Countertops and Sink?

Before you install a sink or countertops, you will need to do some prep.

  • Ranges, refrigerators, dishwashers, and microwaves need to be installed ahead of time
  • Cabinets need to be installed
  • Prior to the template process, a farmhouse or apron sink will need to be installed
  • Have your faucets, soap pumps and cooktops on hand for the template
  • Flooring needs to be installed

The template is the footprint the installer will create and use as a kind of stencil to create your actual countertop. Everything you expect to have in your kitchen will have to be present at the time of the template creation so your installer can account for it in the final cut.

Because there are differences in kitchen layouts and different size slabs, you will probably have to deal with a few seams. You will need to discuss the seam placement with your installer.


A backsplash is an animal onto itself. You will want to confirm ahead of time that your countertop installer can also install backsplashes. Not all of them will do it. For instance, if you are having a subway tile backsplash, you may need to find a tile expert to install.

If you are having a backsplash installed up to the cabinets or around a range hood, it is imperative that the cabinets and hood be installed before measuring. If this doesn’t occur, you could have a very expensive mistake on your hands.

What Do New Countertops Cost?

Most countertops cost anywhere from forty dollars to a hundred dollars per square foot. This includes installation. Concrete countertops are the most expensive at forty dollars to one hundred and twenty dollars per square foot. The deviation in price depends on what region you live in.

Backsplash installation is a separate cost for materials and labor and can vary widely, depending on the material and style you choose.

Steps to a New Sink and Countertops

Making the decision to install new countertops comes can turn into a big investment. It will not only make the kitchen and more attractive but will also increase your home’s overall value.

When someone looks at a new house, they head straight for the kitchen. Yours needs to be a showcase, and new countertops and sink will be a major contributor to the look. There are some steps you will take when making the right decision and installing new countertops.

  1. Selection of countertop and sink
  2. Measurements and templates
  3. Installation
  4. Care and maintenance

1. Selection of Countertop

When choosing to install countertops, there are a lot of options. Some options include:

  • Bamboo
  • Butcher block
  • Concrete
  • Granite
  • Laminate
  • Limestone
  • Quartz
  • Recycled glass
  • Soapstone

They all have their pros and cons. But ultimately, it comes down to your lifestyle. Do you have small children who are hard on countertops? If you do, you might want to choose quartz over bamboo. You also need to consider your taste and budget. Kitchen remodeling is a big investment, so make sure it’s something you want to look at day after day.

Selection of Sink

You will probably be installing a new sink with your countertops. There are many types available. Some of them include:

  • Undermount sink
  • Stainless steel sink
  • Corner sink
  • Kitchen island sink
  • Farm or apron sink
  • Top mount sink
  • Single bowl sink

Once more, it comes down to personal taste and budget as to what style and material you’ll choose. Kitchen sink prices can vary from $200 for a basic style upwards of $2,000 for higher-end models.

2. Measurements and Templates

The installer will need to measure the countertop and sink space. He/she will need to make a template of the different holes (sink, etc.) or stove area, in your kitchen. You’ll want to make sure your cabinets are plumb. They must also be:

  • Level
  • Square to the wall
  • Secured to the wall

3. Installation

Always be on hand or have another adult on hand when the installation is taking place. Questions might arise. You’ll want to give your input so there aren’t surprises after the fact. For instance, discussing and determining where a seam will be.

4. Care and maintenance

Most professional installers will leave you instructions on how to care for your new sink and countertops. But do the research. If you choose quartz, you’ll have little maintenance. Quartz is very durable.

However, if you go with the eco-friendly bamboo, you may need to reapply mineral oil and beeswax periodically. Find out what you’ll need to do for your particular countertop or sink. Hopefully, you’ve done the research upfront so there are no surprises.

Should You Tip Your Countertop Installer?

This is the age-old question when hiring any service worker. When someone is installing a sink or countertop, they are in your home for several hours. Let’s face it; they really work hard, carrying and cutting those slabs and measuring everything to perfection.

And the professional ones try to keep the mess down as much as possible. So, your inclination is to tip. But ask yourself, would you tip your child’s teacher or your doctor? After all, they work hard too. If you insist on doing something, try these options.

  • Give them a beverage
  • Provide a snack
  • Serve lunch

Keep in mind that these are skilled tradesmen, and they might be offended if you offer them a monetary tip. However, you should always make your appreciation well-known by complimenting them to the owner or supervisor. And always share favorable reviews online to acknowledge a job well done. This will bring more of a long-term payoff than your cash tip!

About Jon - Website Owner

Jon Smith

Hi, my name is Jonathan Smith. I have been in the granite business for many years and have worked my way up from an installer helper to an installer and then a countertop business owner. 

I started my countertop company with very little and grew extremely fast because of my knowledge and helpfulness. I started this countertop resource for 1 main reason. That reason is that there are no countertop websites with all the correct information and none of them are from an industry expert like myself. 

I am still in the trade every single day installing countertops, educating people on the type of material they are using for their homes, and making people's dream kitchens a reality.
