How to install undermount sink without clips in 2023

How to install undermount sink without clips

How to install undermount sink without clips?. A sink can be installed without clips, but it requires the proper installation tools and techniques. Undermount sinks are one of the hottest trends in remodeling right now. 

However, they can be more challenging to install than traditional countertop sinks because they do not use clips to attach to the countertop.

In the following post, I will show you how to install an undermount sink with a good guide and a list of materials needed for the job. 

What is an undermount sink?

Undermount sinks are an excellent choice for those with smaller kitchens. They come in various materials and designs, so you can find something that fits your style perfectly!

Sinks are usually installed under the countertop rather than dropped into pre-cut holes as other basins do. This means there’s no rim separating them from what’s on top, making it easier to keep clean when things get messy because everything is right at eye level instead.

 You’ll have plenty of room left over after installing one since these type attachments don’t disrupt much space either way (I mean… unless we’re talking about double bowl installation but still).

U-shaped sinks are the best choice for granite, solid surface, and quartz countertops. They can also be a good fit with laminate but may not provide adequate suction when used on these surfaces because of their shape, making them less effective than drop-in models.

Makes me feel icky even just thinking about it. I don’t recommend undermounts at all, though – they’re usually more expensive too!

Is it hard to install undermount sink without clips?

Proper installation and sealing are crucial to prevent leakage. (A full sink of dishes gets very heavy, you don’t want the countertop pulling apart from underneath on its own!) Undermount sinks are typically attached with a two-part epoxy adhesive that requires an additional step before it can be applied for silicone caulking around perimeter sealant. 

Professionals know how best to handle these situations, so make sure to hire one and get them done as soon as possible if this type applies to your situation at hand! However, if you follow the guide and are confident to install it, it will not be too complicated. 

How are undermount sinks attached?

You can see three types of installation for undermount sinks, distinguished by their different “reveal style.” One type has a very minimal design in which you can’t see much of the installed vessel once it’s done being put into place; another displays more than just an aesthetically pleasing appearance with its exposed rim on top for show-off purposes. 

Finally, the third option leaves both sides covered so that only what needs to be seen is visible at all times – this includes everything from faucets and drain organs down through bowls or plate shelves attached right onto your countertop itself!

  • Nothing is more important than ensuring that your countertops are not exposed when it comes to a professional-looking kitchen. A zero reveal will ensure the edge of any new or replacement surface meets up seamlessly with an opening for sinks to give you everything needed without having anything sticking out like a sore thumb!
  • Positive reveal ensures that some of the sink’s rim is visible past the edge of your countertop. This means you can see all four sides, and it looks cleaner than if no revealing were done at all!
  • The negative reveal of the sink’s rim is not only a clever design element, but it also conceals and reveals at once.

>> The type of sink you get will depend on your preference. If a positive or negative reveal is more appealing, then go for it! 

Otherwise, choose based upon what looks best in the result- don’t be afraid to invest some time into figuring this out since there’s so much variety available when picking from all these beautiful designs nowadays.

You might be thinking that installing an undermount sink is complicated; let’s see my way. In this article, I will show how easy these tasks can seem with help from professional contractors who have installed many types of kitchen faucets in their careers!


You need to clean all the countertop and sink surfaces before getting started!

If possible, it is best that a professional install your new sink before installing so they can take extra care in moving any furniture or appliances out of their way as needed during the installation process. 

In addition, it may require some rearranging on behalf of homeowners with limited home space for such things as storage areas under cabinets.

Before you can install any flooring, make sure that all surfaces are clean and free from dirt. You should also remove grease or anything else obstructing the installation process because these items will get in your way!

When using acetone, use a clean rag to wipe down surfaces. After applying the cleaner and before drying for 5 minutes, make sure that your hands are free from any oil or dirt because this will prevent unwanted stains on the sink or countertops while you wait.

When cleaning with an organic solvent such as isopropyl alcohol (IPA), make sure not to touch anything else besides its intended target- the item that needs fixing! Keep things moving by keeping one hand dry, away from all other items like pots & pans, etc., unless they too need some assistance during their beauty upgrade.

Silicone Adhesive

The adhesives on the market are many and varied. Some can be used for kitchen sink installation, but beware of these strings that might not get you off with just one glue gun!. 

An adhesive material seals around your newly installed vessel after it has been attached to something solid, like a wall or countertop. It’s usually applied in direct contact with surfaces where they will naturally come into contact with water – such as when you turn off the faucet and open up one side, soapy runoff begins flowing down from its edge while cleaning dishes!

We’ll show how these different types work best depending upon their intended use with this handy guide.

A sink has a crucial role in your kitchen. Not only does it collect the food scraps and dirty dishes, but it also helps protect you from any dangerous bacteria that may be lurking under there! That’s why every time we get new countertops installed at our house or renovate an old one like today.

Installing sinks is always part of what needs to be done first because they’re so crucial for maintaining cleanliness throughout all parts of living spaces, such as counters and floors below where things sit during everyday use.

Apply the adhesive to a squeeze porous surface. When you buy an adhesive, make sure that it’s for this type of application and will work best with your sink – unless otherwise directed by manufacturer instructions on the package label or website description!

On one side, there should be two layers: One layer consists solely of wallpaper; another contains textured vinyl paper. First, to apply these papers correctly, start at edges where they meet/overlap themselves (usually along trim lines). Then, once those are aligned tightly against each other, use glue gun-like weapons equipped specifically designed just.


The sink is a good choice for those who want their kitchen to look clean and modern.

If you’re planning on installing an undermount sink, make sure that it’s installed at the bottom of your countertop before installation begins!

After placing the sink on top of your counter, lift it until contact with one side. Look at all the drain openings and use bar clamps or cross braces as needed for stability.

The best way to hang a vessel from these brackets depends entirely upon its size; some will need both types while others only require single uses. If using two pieces together, make sure they have matched colors, so nothing catches against them when in operation!

With a straightforward bar, you can attach your sink to any cross brace. There’s not even a need for nails

The end that grabs onto the bottom of our sinks screws into place, and then we secure it with two additional screws from across our house – one at each corner so nothing will ever loosen up or fall off during rough weather conditions (like hurricanes).

Installing a drop-in sink is easier than an undermount countertop. You have to adjust the position of your new plumbing and tighten up all bar clamps until it’s snug with its intended location on top or next-door neighbor’s refrigerator.

To install your new sink, the first step is applying adhesive under its lip and positioning it in a location that will be satisfactory for installation. 

Once you have found this spot with the help of some indicators placed on top from previous installations or by feeling around blindly until something feels just right – voila! Your beautiful installer has done his job well, so all there’s left to do now are tidy things up before rewashing dishes tomorrow evening.


After installing the new sink, you should use both the countertop and bottom of the sink. To do this properly, you have two options: remove all excess edges by hand or use an adjustable head Phillips screwdriver with a blunt tip for tight areas where there is no room between surrounding surface materials (like coving). 

If possible, try not to over-tighten these clamps as Silicone will start leaking from under them after a while due to deaden sound vibration when tightened too much.

Be sure to join the sink lip with your countertop before removing any excess silicone. It’s best if you can adjust it so that they both fit perfectly, but if not, add some more and remove extra after being dry for an hour or two to avoid cracks from forming when using them later on down the road!

When finishing cleaning the surface, your sink will look clean and shiny. It’s a great feeling to see an old mirror finally come back to life!


Remember to add some extra support when installing an undermount sink without hardware. This will keep your garbage disposal from dropping down and damaging it!

It is always important to be mindful of how much weight a sink can hold. For example, if you fill the garbage disposal with water, it could detach from your countertop!

It is always important to be mindful of how much weight a sink can hold. For example, if you fill the garbage disposal with water, it could detach from your countertop!

It’s essential to add secondary support for the sink when attached; it can be difficult.

This is a quick and easy way to install countertops in your kitchen or bathroom. You can use epoxy that will set quickly, but it’s important for the product you choose to have enough time before installing so people don’t trip over exposed flooring! This is important because it allows for connecting plumbing as soon after installation and without any risk from dirt getting in between seams where they meet the top surface when sticking only one side down with no hardware fasteners holding them together.

The two-part product I used was terrific at this task–it did all my work for me!

You do not need to worry about extra support for the drop-in sink if your countertop provides it.

How to install undermount sink with clips


Bar clamps, stop block, touter, wood braces, file, drill and drill bit, tape measure, silicone adhesive sealant, pencil, ball peen hammer, alcohol, framing square, screwdriver.

Step 1:  

Wipe the inside edge of your cutout and any area around it on a clean, dry surface.

Starting with denatured alcohol to remove any dust from previous projects you may have done or just in general before applying primer, make sure that both surfaces are free from grime so they can get appropriately coated when we’re through!.

Step 2:

  • Apply masking tape to the inside edges of your cutout.
  • Set it over the top.
  • Center it before tracing around its rim.

This will outline where silicone adhesive goes on for easy application without any messes!

Step 3: 

The clip-on sink protectors are ready to go once you have marked out the positions and space for them. You will need at least one in each corner. However, it’s best if there is also another near either side so that they do not get in the way when cutting or sanding around the edge of your sink.

Step 4: 

Before you glue the sink clips onto your countertop, mix a solution of two-part epoxy and spread it over their base. It’s important that you press down on each stud until they are fully embedded in place with enough pressure for at least 24 hours to cure correctly!

Step 5: 

You apply the bead of silicone on the edges of cutout in the line with accurate draw when the eposixed clip studs cured. Next, center the fixture onto the opening and make sure all four sides emerge equally from under the work stand for an even reveal without gaps or cracks in sight!

Step 6: 

When you’re satisfied, slip the slotted sink-clip brackets onto the studs so that one end bears on your rim. Thread wingnuts and tighten them down till they are finger tight before securing in an alternating pattern to prevent any excessive strain from happening when installing or removing this fixture at different points during home improvement projects

Step 7: 

Cleaning up around the cutout edges is an integral part of finishing your project. Keep your workspace clean and well ventilated to avoid the risk of silicone fogging up. Be sure wipe away any spilled gooey stuff before applying other materials, like paint or varnish for example!

I always make sure there isn’t anything left behind when I’m done with my DIY. That means using alcohol on top surfaces as well as between them because some people forget about this step, but if you’re doing work near sharp things, don’t take chances- cover everything at once

Step 8:

Mount the faucet and, if applicable, accessory dispensers.

Connect water supply tubes from your new sink to a nearby fixture for easy access if you need it later on, or plan by screwing an outlet right onto one of these kitchen sinks!

Where to buy?

You can easily find the undermount sinks in any kitchen appliances stores or order online through E-commerce sites. Amazon is always one of the best recommendations. 

FAQs about install undermount sink without clips

Q1: Do undermount sinks need clips?

Installing an undermount sink is simple and can be done in several ways. Most methods are acceptable, but some installers prefer clips or brackets, while others use glue to attach them securely into place on your countertop.

The installation process varies depending upon which training the plumber had when they were doing work like this, so make sure you ask if there’s anything special you need before getting started!

Q2: Is Silicone enough to hold an undermount sink?

No, caulk is not usable as the adhesive and will leave behind a residue when trying. Most sinks come with installation instructions that are very clear about what type of material should be used instead.

The use-case for Silicone on granite surfaces seems limited mainly because it does not stick well without help from another medium like polyurethane.

Q3: Is epoxy strong enough to hold an undermount sink?

To ensure the integrity of your stone top installation, we use high-strength epoxies and fast-drying two-part compounds. These products have incredible tensile strength once dry, which will hold up under any force put on them during use or even after years without maintenance!

Q4: Do undermount sinks get mold?

The one big drawback to undermount sink installation is that it can cause water problems. This has been an issue due to certain countertop materials and how they react with moisture from washing dishes or pouring drinks on them. But proper knowledge about this type of installation will help keep your home happy-go-lucky while also ensuring its structural integrity!
