Why Is an Undermount Sink Unique?
If you are fed up with the extra cleaning of the sink rim every two days, and worried about the sink catching a mold, let me introduce you to undermount sinks. These are sinks mounted from beneath the countertop and lack a rim. The sinks are either glued to the counter or sometimes even screwed or buttoned from below. They are usually made of either stainless steel, granite composite or porcelain ceramic. Due to the lack of a rim, cleaning in and around the sink is easier.
Undermount sinks were first introduced in the 1960’s, back when laminate countertops (with wooden core) were popular throughout the US. The design of undermount sinks didn’t really find its place in the 1960’s kitchen models. The real change happened with the introduction of solid surface countertops (made with acrylic resin and natural minerals) in 1967.
The Design Behind A Drop-In Sink
People almost never want to compromise the aesthetics of their kitchen, especially not when it’s the kind of countertop they are choosing. These drop-in sinks are attachable to almost any countertop that’s available out there. Drop-in sinks are basically sinks with a rim/ lip around their perimeter which can easily sit on any countertop without the risk of damaging it. This rim protects the countertop from the risk of spillage. Underneath these sinks, a layer of silicon caulk is used along with clips (attached from underneath the cabinet) making them immobile.
Drop-in sinks were introduced to support cheap plumbing solutions. These were easy to replace and protected most countertop materials, mostly the laminate ones that were popular during 1980’s to 90’s that had a wooden core.
Undermount vs Drop in Sink: Which Is Better?
I remember when I first remodeled my house, I was stuck with this one choice whether to go for undermount sinks or drop-in sinks for both my bathroom and kitchen. That’s when I did my research and here’s what I found.
Investment And Resale Purposes
The first thought that popped up in my mind before choosing the kind of sink I wanted to install was how it would affect the resale value of my house.
- Undermount sinks provide a chic finish to your kitchen countertop and an unmatched look to your bathroom vanity countertop. Interior designers often prefer undermount sinks for a modern aesthetic appeal. Remodelling your bathrooms and kitchen with an undermount sink can significantly increase your house’s resale value, making it a good choice for investment purposes.
- Although Drop-In sinks are cheaper to install or replace, they do not significantly increase the resale value of your property. The installation might reduce the cost of remodelling your bathrooms or kitchen.
The Compatibility Test
Before making a decision, it is important to understand how these sinks pair with kitchen and bathroom countertops.
- Undermount sinks require specific waterproof materials when it comes to the kind of countertop you choose. These are strictly compatible with materials like quartz, marble and granite. This restricts the kind of design one can opt for while remodelling their houses.
- Drop-In sinks are versatile and compatible with almost all kinds of countertop available in the market.
Which One’s Easier To Maintain
Maintenance can affect the appearance and longevity of a sink. Let us see which option requires less upkeep.
- Due to the lack of a rim or lip, Undermount sinks are comparatively quite easy to clean. There are no hidden edges in this sink which makes it easier to clean it with just one swipe.
- Drop-in sinks require routine cleaning as dirt, food crumbs and grease gets trapped in the edges. In case of a repair issue, water can damage the countertop and you may incur a hefty expense.
Visual Appeal
An aesthetic sink can amplify the visual beauty of your kitchen.
- An undermount sink can give your kitchen a modular appearance. The lack of a rim/lip provides a seamless finish to the countertop. Smooth edges of quartz or a granite countertop amplifies the eye-pleasing interior of your home.
- Drop-In sinks have a visible rim that sits on top of the countertop. Many homeowners can find it less seamless as compared to the undermount sink. However, they can still look visually appealing when paired with the right materials, finishes and countertop designs.
Undermount Vs Drop-in Sink Pros And Cons
So far we’ve covered the key differences between the two kinds of sinks. Before we make a final decision, let us review the benefits and the disadvantages of both sinks. These will help you understand them in depth and give you a clearer idea of which option is a better fit for your home.
Undermount Sink
Pros
Undermount sinks can increase the resale value of your home by almost 2% as they add to the aesthetics of your countertop. Moreover, these are highly known for allowing effortless cleaning of your kitchen as well as bathroom vanity countertop. An undermount sink can add to your kitchen efficiency by providing more space on the counter due to the absence of a rim.
Cons
Installing an undermount sink requires high precision cutting and structural support, increasing the cost of installation significantly. Moreover, only a few special kinds of countertops complement undermount sink installation which can reduce the number of design choices you have. Replacement of an undermount sink can be tricky and might bring damages to the entire countertop.
Drop-In Sink
Pros
A drop-in sink can be installed to any kind of countertop making it universally compatible. The total cost of installation as well as the cost of the sink are relatively much lower than undermount sinks. You can easily install a drop-in sink using DIY installation methods and won’t require a professional in most cases.
Cons
Lower resale value, harder counter cleaning and rougher edges around the sink perimeter are some of the drawbacks of a drop-in sink. Moreover, a drop-in sink can hamper with the aesthetics of a countertop, leaving a cheap undefined look.
Where Undermount And Drop-In Sink Work Best
Whether to opt for an undermount or drop-in sink for your bathrooms and kitchens is highly variable. Bathroom vanity countertops get wet more frequently and require much more maintenance than a kitchen countertop. A kitchen countertop on the other hand is a crucial place to manage hygiene and germ protection.
Considering an undermount sink for your bathroom vanity would be an optimal choice since it brings ease in frequent cleaning, keeping the surface dry, and preventing long term mold-damage. Bathroom vanities often facilitate frequent water usage, the reason why flexible faucet placement is important. Having an undermount sink allows you to install a faucet wherever you please around the sink perimeter.
A kitchen on the contrary, can facilitate both an undermount sink or a drop-in one. Cleanliness and hygiene remain crucial to its maintenance. Kitchen countertops are usually massive in size, providing ample space for cleaning and wiping the surface.
Common Mistakes To Avoid When Choosing A Sink
The right type of sink can make everyday tasks more convenient, while the incorrect one can create unnecessary maintenance and installation issues. Here are some common mistakes to avoid before choosing the sink.
Basin Depth
Basin depth can impact your cervical health.That’s right, choosing a sink that is too deep might strain your back from bending for too long at once. Also, if the sink is too shallow, it might overfill and splash water outside on the floor. A basin
should have accurate depth to avoid both these issues.
Material Durability Matters
Choosing a sink that doesn’t scratch or dent after heavy use can save hundreds of dollars of plumbing cost. An aesthetic sink with less durability can damage your countertop over a few months to years. For instance, enameled thin steel sinks can chip quickly and attract rust, acrylic and fiberglass sinks are not heat resistant and can melt from hot pans if directly placed.
Inconvenient Faucet Placement
Before installing a sink check for the right place to fit your faucet. If placed incorrectly it’s usage can be extremely inconvenient. The right placement is when water from the faucet directly aims at the drain, this helps avoid water pooling and water splashing. Incorrect faucet placement can hamper with kitchen efficiency too.
Mounting Style
Choosing an undermount sink for a countertop material that isn’t water proof can lead to entire countertop replacement. On the other hand, choosing a drop-in sink for a granite or marble top can be a huge design mistake. If you hate scrubbing and don’t like cleaning, installing a drop-in sink might be a big mistake.
Forgetting Countertop Support
Heavy materials like granite require extensive support to prevent cracking and breakage. The cabinets beneath need to be structured properly to hold a heavy sink in place. If ignored, this can tear the plumbing joints and spill soapy water directly on your wooden cabinets. Moreover, leakage from cracks can attract mold.
Conclusion
When it comes to the choice between undermount vs drop in sink, you can choose either one. The choice depends upon factors such as installation charges, maintenance, countertop material, budget and overall design preferences. Once the countertop has been chosen, it becomes much easier to choose a sink that can be functional and visually aesthetic.
Keep in mind how the sink adds to your house’s resale value. Now this can vary for individuals, investing in a sink that saves repair cost, plumbing cost and prevents cracking of countertop can also be a thoughtful investment decision. On the contrary, an aesthetic sink that needs some maintenance over time can add to up to 2% of the resale value of your home.
Also remember that sinks can influence efficiency in kitchen and bathrooms differently. One sink might prove to be good for your kitchen and inefficient for your bathrooms and vice versa. Also, measuring placement of faucet and sink width are essential before installing a sink.
