Can You Have An Undermount Sink In Laminate Countertop?
Can you have an undermount sink in a laminate countertop? – A question I get asked all the time as a kitchen designer!
This query brings together two beloved elements of kitchen decor, the sleek undermount sink and the budget-friendly laminate countertop.
However, traditionally, these two components haven’t always mixed well due to technical constraints. But with evolving technologies and innovative solutions, the game is changing (sort of).
Let’s get into it!
Can You Have An Undermount Sink In Laminate Countertop?
Technically, yes. There are particular ways and circumstances when you can fit an undermount sink into a laminate countertop. However, in most regular instances, I would not advise this.
Traditionally, undermount sinks are not recommended for installation with laminate countertops because the cutout in the laminate for the sink leaves a raw edge susceptible to water damage.
This is because the laminate countertop is not solid laminate all the way through. Underneath the top laminate layer and inside the countertop it is made from particleboard, which is not water-resistant, and if it gets wet, it can swell and become damaged.
However, there are workarounds and ways to have an undermount sink with a laminate countertop. It just requires careful installation and specific types of sinks or countertops to prevent potential water damage.

Ways You Can Have An Undermount Sink In A Laminate Countertop
For many years, laminate countertops and undermount sinks seemed incompatible. The issue arises from the particleboard core of laminate countertops, which is susceptible to water damage.
However, thanks to advances in technology and innovative installation methods, there are now ways you can have an undermount sink with a laminate countertop.
Compact laminate is an innovative material that offers an excellent solution for those who want the budget-friendly nature of laminate but also desire an undermount sink.
Unlike traditional laminate, which has a particleboard core, compact laminate is made from layers of kraft paper impregnated with resin, which are compressed under high heat and pressure to create a solid, waterproof material. No particleboard in sight!
This difference in construction means that compact laminate can handle the water exposure around the cutout for an undermount sink without swelling or becoming damaged.
As a result, you can install an undermount sink just like you would with a granite or quartz countertop, using silicone adhesive and anchor clips to secure the sink to the underside of the countertop. You can even cut in some drainer grooves for your sink too!
This solution offers the benefits of laminate counters, such as affordability and a wide range of design options, but with the added advantage of being able to have an undermount sink and get that streamlined look.
Karran is a manufacturer that has developed a special type of undermount sink designed specifically for use with laminate countertops. These sinks have a unique rim that is bonded to the underside of the countertop using a combination of a specially formulated adhesive and a unique installation process.
The key to the Karran system is creating a watertight bond between the rim of the sink and the laminate countertop. This is achieved by applying the adhesive to the rim of the sink and then clamping it to the underside of the countertop until the adhesive cures. Once the adhesive has cured, any excess is removed, and the edge of the cutout in the laminate is sealed with silicone to prevent water exposure.
By using this method, you can have an undermount sink with a laminate countertop without the worry of water damaging the particleboard core. The result is a seamless integration between the sink and countertop, creating a clean, modern look.
To be completely honest, I’ve never used one of these Karran sinks in any of my projects but I am aware that they are an option. However, in my opinion, it feels a little complicated for the results you get.
While these solutions do allow for the use of an undermount sink with a laminate countertop, it’s important to note that they should be carried out by a professional or an experienced DIYer to ensure a watertight seal and a secure installation.

What Sinks Are Suitable For Laminate Countertops?
Drop-in sinks (inset sinks) are the most suitable type of sink for laminate countertops.
Laminate countertops have specific requirements when it comes to choosing a sink because they are made from a particleboard core that is susceptible to water damage.
Drop-in sinks are perfectly suited to installation in laminate countertops as they simply drop into a hole cut out of the countertop. The lip of the sink then rests on top of the counter, protecting the edges of the cutout from water exposure.
Drop-in sinks come in a variety of sizes and materials, from small single bowls to larger double-bowl sinks and everything in between. They are also available in stainless steel, ceramic, composite and copper to name a few.
What Countertops Are suitable for an undermount sink?
Undermount sinks require a solid (same material all the way through), sturdy countertop material that is waterproof and can support their weight and installation style. Here are some popular countertop materials that are suitable for undermount sinks:
- Granite: One of the most popular choices for undermount sinks, granite countertops offer strength and durability. They can easily support the weight of the sink, and their waterproof nature makes them an ideal match.
- Quartz: Like granite, quartz countertops are extremely strong and can easily handle the weight of an undermount sink. Plus, quartz is non-porous, making it resistant to water and stains.
- Marble: Marble countertops can also be used with undermount sinks, lending an elegant and timeless look to your kitchen or bathroom. However, marble requires a bit more maintenance to prevent staining.
- Solid Surface: Solid surface countertops, such as Corian, are a mix of natural minerals and clear resin, creating a durable, non-porous, and repairable surface. This makes them suitable for undermount sinks.
- Concrete: Concrete countertops are also a solid option for undermount sinks. They are custom-poured, allowing for a perfect fit, and offer a unique aesthetic.
- Porcelain Composite: Porcelain countertops, such as Dekton and Neolith are extremely durable and highly resistant to heat, scratches, and stains, these porcelain composites are a great choice for undermount sinks.
Materials like laminate or tile, which are not solid throughout or may not handle the weight of an undermount sink, are generally not recommended unless specific installation methods are used to protect the material and ensure a secure installation
There you have it! The mystery of whether you can have an undermout sink in a laminate countertops, solved!
For most instances of regular laminate worktops and your average undermount sink, pairing these two items together is a big no-no!
However, technically, it is possible to install an undermount sink in a laminate countertop, you’ll just need the correct type of laminate or a very particular make of sink.
