Undermount vs Drop-In Sink – Which Is Best For Your Kitchen?
When planning a kitchen remodel there are seemingly hundreds of choices to make, including kitchen sink options. And in the world of sink choices, the choice between an undermount or a drop-in sink is probably the most common I come across.
You might be thinking, “Is there really a big difference?” But both types come with their unique set of features, advantages, and drawbacks that can affect your daily kitchen chores and overall style.
In this post, I’ll compare undermount and drop-in sinks, talk about the pros and cons, and give you the knowledge you need to make an informed decision.
So, let’s get started and plunge right in! 😀
What are Drop-In Sinks?
Drop-in sinks, (also known as top-mount sinks or inset sinks) are a type of sink that is designed to be installed from above the countertop, with its rim sitting on top of the counter surface.
They are one of the most common types of kitchen sinks and as the name suggests, these sinks “drop into” a hole cut out in the countertop, with the sink’s rim or lip resting on top of the counter surface. This design creates a raised lip edge that bears the sink’s weight and holds it securely in place.
Installing a drop-in sink is generally straightforward. It involves cutting a hole in the countertop to match the dimensions of the sink. Once the hole is cut, the sink is dropped in (hence the name), and its weight is supported by the rim that sits directly on the countertop.
The sink is then sealed (caulk) around the edges to prevent water from seeping underneath. This ease of installation makes drop-in sinks a popular choice for DIY enthusiasts.
Drop-in sinks come in a plethora of materials to match any kitchen style. Some of the most common materials include:
- Stainless Steel: Praised for its durability and easy maintenance, stainless steel is a top choice for many homeowners. It seamlessly integrates with most kitchen designs, providing a sleek and modern look.
- Porcelain or Ceramic: Known for their classic appeal, porcelain or ceramic sinks are perfect for achieving a timeless or country-style kitchen design.
- Composite Granite: Composite granite sinks are loved for their high resistance to heat, scratches, and stains. They come in multiple colours, offering more aesthetic choices compared to stainless steel.

Advantages of Drop-In Sinks
Drop-in sinks, known for their practicality and versatility, come with a host of benefits that make them a preferred choice for many homeowners. Some of these advantages include:
- Easy Installation: The installation process for drop-in sinks is straightforward. They can be installed by anyone with a bit of DIY knowledge and ambition, potentially saving on professional installation costs.
- Cost-Effective: Drop-in sinks are typically cheaper than undermount sinks. Their cost-effectiveness extends not just to the sink itself, but also to the cost of installation, making them an excellent option for those working with a tighter budget.
- Versatility in Design: Drop-in sinks are available in a plethora of styles, sizes, and materials. So whether your kitchen vibe is modern, rustic, or a timeless classic, you’re sure to find a drop-in sink that complements your decor.
- Built-in Drainer Section: Many drop-in sinks come with a built-in drainer section (drainboard sink) as part of the sink. This handy feature provides a dedicated space for drying dishes or draining washed vegetables, adding to the sink’s functionality and convenience.
- Compatibility: Unlike undermount sinks, drop-in sinks are compatible with virtually all types of countertops, including laminate and tile.
- Easy to Replace: The design of drop-in sinks makes them much easier to replace than undermount models. If your sink gets damaged, or you simply fancy a change in your kitchen’s look, a drop-in sink would be a hassle-free choice.
Disadvantages of Drop-In Sinks
While drop-in sinks have many practical advantages, they also have some limitations. Some of the disadvantages include:
- Aesthetic Limitations: Drop-in sinks have a rim that sits on the countertop. This can interrupt the smooth look of your countertop and may not align with modern, minimalist kitchen designs.
- Sink Cleaning Challenges: The rim of a drop-in sink can collect dirt and debris over time. This could require more thorough cleaning compared to undermount sinks, which offer a seamless transition from countertop to sink.
- Space Constraints: The rim of the drop-in sink eats into valuable counter space. If you have a smaller kitchen, every inch counts, and this could be a drawback.
- Water Spillage: With drop-in sinks, water and spills can’t be wiped directly into the sink from the countertop because of the protruding rim. This could lead to water pooling on the countertop around the sink.

What are Undermount Sinks?
Undermount sinks, as their name implies, are mounted under the countertop, resulting in a seamless transition from countertop to sink.
Unlike drop-in sinks, the installation of under-mount sinks is a little bit more complex and typically requires professional help. The sink is attached directly to the underside of the counter using a strong adhesive and metal clips or anchors (clip fasteners), if necessary.
The edge of the countertop along the sink cutout is then finished and polished for a clean look. It’s important to ensure a watertight seal between the sink and countertop to prevent any potential water damage.
This type of sink is known for its sleek, modern aesthetics that can add a touch of style to any kitchen design.
Undermount sinks can be made from a variety of materials, similar to drop-in sinks. Here are some common materials you might encounter:
- Stainless Steel: Again, stainless steel’s durability and minimalistic look make it a popular choice. Its resistance to heat and stains is a bonus.
- Solid Surface: Solid surface materials like Corian are often used to create sinks that seamlessly integrate with the countertop, providing a sleek, continuous surface.
- Granite or Quartz Composite: These sinks offer incredible durability and a range of colour options. They’re highly resistant to heat, stains, and scratches.
- Copper: A less common but still interesting choice, copper sinks add a warm, rustic touch to the kitchen. Copper is naturally antimicrobial, which can be a plus for hygiene-conscious homeowners.
- Fireclay: A type of ceramic, fireclay sinks are renowned for their durability and resistance to scratches, stains, and heat. They often come in white, providing a classic and timeless look.

Advantages of Undermount Sinks
Undermount sinks are popular for their sleek aesthetics and functional benefits. Here are some advantages they offer:
- Seamless Aesthetics: One of the most appealing features of undermount sinks is their seamless integration with the countertop. This creates a smooth, continuous surface that can lend a sleek, modern look to your kitchen.
- Easier Cleaning: With no sink rim to worry about, wiping down your countertop is a breeze. You can push spills and crumbs directly into the sink with no obstacles, making your post-cooking cleanup much easier. Although it can get a bit of gunk on the underside of the countertop inside the sink itself.
- Space-Saving: As undermount sinks are installed beneath the countertop, they can save you valuable counter space, giving you a bit more room for prep work.
- Customizable Faucet Placement: Since there’s no pre-drilled faucet hole, you have the freedom to place your faucet anywhere that works best for you. This could mean more convenience and better use of space.
Disadvantages of Undermount Sinks
While undermount sinks generally win when it comes to style and functionality, they do come with some limitations. Here are a few you should be aware of:
- Complex Installation: Installing an undermount sink is more complex than a drop-in model and often requires professional help. The sink must be correctly and securely mounted to handle the weight, and the countertop edge needs to be perfectly finished. These requirements can add to the installation cost.
- Higher Cost: Undermount sinks are usually more expensive than drop-in sinks. The higher cost extends not just to the sink itself, but also the installation and the need for a countertop material that is compatible and can support the sink.
- Compatibility Issues: Undermount sinks require solid, waterproof countertop materials such as man-made or natural stones like quartz, granite and marble. They’re not compatible with tile or laminate countertops due to their weight-bearing requirements and potential for water damage along the countertop edge. They will, however, work with compact laminate countertops.
- No Built-In Draining Board: Unlike some drop-in sinks, undermount sinks do not come with a built-in draining board section. If you require a draining board, you’ll need to have it cut into your countertop. This will add to your installation costs and should be factored into your budget when considering an undermount sink. This feature also requires careful planning in terms of space and countertop material.
- Potential for Damage: If an undermount sink isn’t installed properly, it could lead to water damage in your cabinets over time. The risk is minimal with professional installation but is still something to be aware of.
Undermount vs Drop-In Sink: The Major Differences
Choosing between an undermount and a drop-in sink involves understanding the major differences between them. In this section, I’ll provide a comparative analysis based on various factors such as cost, installation, maintenance, and appearance.
On the whole, undermount sinks are typically more expensive than drop-in sinks. The higher cost isn’t just limited to the sink itself; it also includes the cost of installation. Undermount sinks often require professional installation due to their complexity, adding to the overall cost.
On the other hand, drop-in sinks are usually more budget-friendly, both in terms of the sink’s price and the installation process. Their simple ‘drop and seal’ installation can often be a DIY project, helping you save on professional installation costs.
Undermount sinks are installed underneath the countertop, providing a seamless transition from the counter to the sink. This installation requires precision and, usually, professional help to ensure the sink is securely attached and sealed.
Conversely, drop-in sinks are inserted into a hole cut out of the countertop, and the rim of the sink rests on top of the counter. This installation process is generally easier and can often be handled by DIY enthusiasts.
Undermount sinks offer easy maintenance as there is no rim where grime and debris can accumulate. You can simply wipe spills and crumbs straight into the sink. However, you can get a bit of grime build up on the underside of the countertop where the sink and counter material meet.
Drop-in sinks, however, have a rim that sits on the countertop, which may require additional cleaning effort to keep the area where the sink meets the counter grime-free.
Undermount sinks offer a sleek and modern look to your kitchen. They allow for a smooth, uninterrupted flow from the countertop to the sink, which can contribute to a minimalist aesthetic.
Drop-in sinks have a more pronounced presence with their visible rim, contributing to an arguably more traditional kitchen aesthetic. They offer a classic appeal and can be an excellent match for rustic or traditional kitchen designs.
|Factor||Undermount Sinks||Drop-In Sinks|
|Cost||Typically more expensive||Generally less expensive|
|Installation||Professional installation needed||Easier, often DIY, installation|
|Maintenance||Easier due to lack of rim||Extra cleaning around the rim|
|Appearance||Sleek and modern||Classic and traditional|
Remember, the decision between an undermount and a drop-in sink should ultimately meet your unique needs and personal preference.
Factors to Consider When Choosing Between Undermount and Drop-In Sinks
Choosing between undermount and drop-in sinks depends on several factors, as both types come with their own set of benefits and drawbacks. Here are the key considerations to help you make an informed decision:
- Budget: Your budget plays a significant role in your decision. Drop-in sinks, as well as their installation, are typically less expensive than undermount sinks. If you’re looking to save costs, you might lean towards a drop-in option.
- Countertop Material: The type of countertop you have can also dictate your sink choice. Solid, waterproof countertops like granite, marble, quartz, or solid surface are necessary for undermount sinks, whereas drop-in sinks are compatible with almost all types of countertops, including laminate and tile.
- Kitchen Style: Your kitchen style might also influence your decision. If you prefer a sleek, modern look, you might lean towards an undermount sink. If you’re going for a traditional or rustic aesthetic, a drop-in sink (or farmhouse / butler sink) might align better with your decor.
- Cleaning Preference: If you prefer easy cleanup with the ability to swipe debris directly into the sink, an undermount sink would be more suitable.
- Installation Preference: If you’re a DIY enthusiast looking to install the sink yourself, a drop-in sink is generally easier to handle. On the other hand, if you’re planning to hire a professional or are undergoing a complete kitchen remodel, the complexity of installing an undermount sink might not be a significant issue.

Which is better an undermount sink or a drop-in sink?
There’s no absolute answer to whether an undermount sink or a drop-in sink is better – it truly depends on your personal preferences, needs, and specific circumstances.
An undermount sink offers a sleek, modern look and allows for easy cleaning because there’s no lip to catch debris. They’re great if you prefer a minimalist design and enjoy being able to sweep debris straight off the countertop and into the sink. However, they tend to be more expensive and require professional installation, which adds to the cost.
On the other hand, a drop-in sink is generally more budget-friendly and easier to install, making it a suitable choice for DIY enthusiasts. They also work with a wider range of countertop materials, including those that may not be solid throughout and compatible. As well as those that can’t support the weight of an undermount sink. However, they do have a visible lip that can catch crumbs and cause a food buildup making cleaning a bit more of a chore.
Therefore, the “better” choice between an undermount sink and a drop-in sink will depend on your budget, the countertop material you have or plan to install, your aesthetic preferences and your cleaning habits.
Personally, I prefer an undermount sink. But that’s just me! 😃
Here are some frequently asked questions about undermount and drop-in sinks to provide you with more insights:
Can I replace a drop-in sink with an undermount sink?
Yes, it is possible to replace a drop-in sink with an undermount sink. However, it’s important to note that this process may require a significant amount of work. The countertop will need to be able to accommodate the undermount sink and may need to be cut or modified.
Additionally, undermount sinks require solid, waterproof countertop materials, so if your countertop is laminate or tile, an undermount sink may not be the best choice.
Which type of sink is easier to install?
Drop-in sinks are generally easier to install compared to undermount sinks. Their installation is often a simple “drop and seal” process that many DIY enthusiasts can handle
Which type of sink is easier to clean?
Undermount sinks are often easier to clean because of their rimless design. They allow you to wipe spills and crumbs straight from the countertop into the sink without any obstructions. Drop-in sinks, however, have a rim that can catch crumbs and spills, making them a bit more challenging to clean.
Can an undermount sink become a drop-in sink?
Transforming an undermount sink into a drop-in sink can be complicated. While theoretically possible, it would likely require substantial modifications to both the sink and the countertop. It’s generally more feasible to replace the sink rather than attempt to convert one type to the other.
There are some sink models on the market that can be either/or (undermount/insert).
Which sink type is more durable?
The durability of a sink is less about the type (undermount vs drop-in) and more about the material it’s made of. Both undermount and drop-in sinks can be extremely durable if made from high-quality materials like stainless steel, fireclay, or cast iron.
Regular maintenance and proper installation also play a significant role in a sink’s lifespan.
There you have it! Everything you need to know if you’re deciding between an undermount and drop-in sink.
Both types of sinks offer unique advantages and have their specific considerations.
Remember, the decision isn’t just about the look you prefer; it’s also about your budget, countertop material, your DIY abilities, and your maintenance preferences.
