Drop-in sinks are typically less expensive than undermount sinks. This is because drop-in sinks are designed to be installed by simply resting them into a hole in the countertop, a relatively easy process.
This installation method also limits what materials an under-mount sink can be constructed from as some materials are not compatible with all counter-tops. More expensive: Undermount sinks tend to be more expensive than drop-in sinks.
Some say drop-in is generally the best option because it's easier to access all parts of the sink for cleaning. However, both types of sinks tend to accumulate grime along the caulk line where the sink meets the counter. Where an undermount sink rim and counter meet, the caulked gap can be trickier to clean.
Since undermount sinks to not have anything above the counter to help carry their weight, they need more support. They also need more solid countertops that don't suffer easily from water damage. This often makes them a more expensive sink than other options and also makes installation more difficult.
Undermount sinks are simply more practical, functional and aesthetically pleasing than overmount sinks. With undermount sinks, it is really easy to wipe food crumbs from the countertops into the kitchen sink. There is no edge, no seam and no calking in the way.
Pros of an Undermount Sink
Undermount sinks are: Easy to clean: Countertop cleanup is more streamlined with undermount sinks since you can wipe any spills or crumbs directly into the sink. Highly durable: Undermount sink types can be worth the price for their durability and quick countertop cleanup.
An undermount kitchen sink is easier to clean. Since your countertops are below your sink, there will be little need for scrubbing them. You will also have less counter space, so cleaning will take less time. With less counter space, you will also have less waste from pans and pots.
Marble and granite
In this case, they are ideal for undermount sinks because they also happen to be durable. The fact that they are porous also helps in helping the adhesives bind more firmly with the stones. Despite what most people think, marble is not a “soft” stone.
Can I Hire a Plumber for Undermount Sink Installation? Installing a sink is no small task, so you may want to hire a plumber to ensure it's connected properly and leak-free. Plumbers charge between $45 and $200 per hour on average. Installing a sink only takes about an hour.
Stainless steel sinks offer a complementary look for quartz countertops and can bring out different colors and patterns in the natural stone. Stainless steel is durable and water-resistant. It's also easy to clean and lends an industrial, urban visual to your bathroom space.
Rimmed sinks work well with all countertops. Whether you have a granite, marble, or soapstone countertop, a drop-in sink will go in without any hiccups. Undermount sinks, on the other hand, work well with all countertop materials except custom tile and laminate tops.
Replacing a drop-in sink is easier as there are fewer additional holes in the countertop and will save you money. It is, however, more difficult to replace this sink with an undermount sink. If you choose to replace your old drop-in with an undermount sink, keep in mind the edges of the counter cutout will show.
Because drop-in sinks are an older design, many would-be home buyers consider them to be dated; undermount sinks, on the other hand, are often seen as a sign of a more recent, higher-end (and thus more valuable) kitchen.
Moldy or Cracked Caulk: Just like topmount sinks, undermount sinks on granite and quartz need to be sealed to prevent moisture from creating mold and mildew problems in the cabinet.
Weight: Stainless steel or copper sinks tend to be the lightest, while vitreous china, porcelain, ceramic and composites are moderately heavy. Choose a heavy stone, cast iron or enameled-steel undermount sink only if you're sure the countertop can support the weight.
Undermount sinks are a popular choice for many homeowners because they offer a sleek, seamless look that is easy to keep clean. Because there is no lip around the edge of the sink, it is easier to wipe debris directly into the sink, rather than having to clean around the rim of the sink.
'The easiest kitchen sink material to maintain is going to be one made of stainless steel, copper, cast iron or enamel because they will not support microbial growth as they are not cellulose material,' says Darren Hudema, director of training and technical services at PuroClean.
Laminate countertops are a budget-friendly option for undermount sinks. Laminate countertops are easy to clean and maintain, but they can be scratched or damaged by heat.
Undermount sinks also remain popular, with Beesley sharing that they're “a popular choice for customers as they are installed under the level of the worktop creating a seamless design. These types of sinks save space, and create a clean and sleek look which is great for minimalist-style kitchens.”
Proper Sink Installation
Then, form an initial seal by applying an adhesive (usually a two-part epoxy but sometimes silicone) to the sink before attaching it to the underside of the counter. Then seal the gap with silicone caulk. Look for mold-free or mildew-resistant caulk designed for kitchens and baths.
5.8 - Clean off silicone residue on the edge of the sink. 5.9 - Apply some silicone to the nuts. 5.10 - Wait an hour before turning the counter over and placing it on the cabinets. 5.11 - Wait 24 hours before using the sink.
