Best Undermount Bathroom Sink Buying Guide
Weight
The weight of your undermount sink can factor into your installation process. The heavier your sink is the more support it will require in the cabinet beneath it. However, a heavier sink can signal durability and longevity.
Usually, materials like fireclay, marble or granite are heavier and can stand heavy use. Lighter sinks made from plastic, copper, porcelain or other materials are easier to install and are also durable, but they may need extra care down the line.
Material
Your sink's construction materials can make a huge difference between liking and loving your bathroom sink. Natural stone materials like granite or quartz can be cumbersome and expensive but distinctive.
Copper sinks have a unique finish that can add a statement to your bathroom, but these are also more expensive and require extra care.
Plastic sinks are a little easier to maintain, but can also stain over time. Porcelain and ceramic sinks are a great compromise between durability and affordability.
Color
In the past, bathroom sinks have been traditionally white, since white creates a fresh and clean look. Now there are more options than ever. You could choose a textured granite composite sink with flecks of several colors or a copper sink that can change color over time.
You will want to pick a sink that will either match your surrounding bathroom decor or create a striking contrast. A good undermount bathroom sink in a unique shade can subtly add a splash of color to an otherwise ordinary room.
Drain
The drain in a bathroom sink need not be too fancy or too plain. Because the sink is an unexpected place to apply style, you can jazz up your sink's appearance with a fancy drain.
Always be sure the drain is large enough to accommodate your needs. If you use the stopper a lot, be sure the seal around the drain can be secured tightly to prevent water loss. Many contemporary sinks use a pop-up drain unit to make stopping up the sink quick and easy.
Bowl Shape
The shape of your sink bowl can make all the difference in your bathroom. Round bowls can make a statement, while oval bowls are more traditional. Square or rectangular bowls evoke a more modern and contemporary look that could be great for minimalists.
If you wish to truly stand out from the crowd, consider getting an asymmetrical bowl that will be eye-catching and a conversation starter. Think about cleaning time, too, since bowls with more edges and levels may require some extra cleaning attention.
Types of Bathroom Sinks
Drop-In Sinks
These types of sinks are also called self-rimming sinks. A hole is cut into the countertop and the sink is lowered into them from above. Countertops do not have to be customized for this type of sink.
Standalone Sinks
Standalone sinks, or console sinks, come with their own cabinetry and are not mounted to the floor or wall. Only the plumbing keeps them in place. They're great for small spaces.
Undermount Sinks
Undermount sinks are installed within granite, quartz or other type of fancy countertops. Due to the installation process, the countertop must be customized according to the size and shape of the sink. These sinks are installed from below the countertop instead of from above.
Vessel Sinks
These sinks are usually statement pieces that sit above the countertop instead of being recessed within a counter. They attach to the counter by way of the drain or mounting ring, depending on the shape and weight of the bowl.
Pedestal Sinks
This kind of sink has a single foot that is mounted to the floor. Pedestal sinks are usually all one piece and don't have much surface area around the sink bowl. They are often seen in smaller bathrooms.
Wall-Mounted Sinks
Great for small spaces, a wall-mounted sink is attached to the wall with the plumbing pipes exposed underneath. This can give you more room underneath the sink, but be sure to not place too much weight on this sink.
Bathroom Sink Materials
- Porcelain: Cast iron sinks enameled with porcelain can look beautiful and last a long time. This material looks polished and expensive. It's also one of the most common types of bathroom sinks. Porcelain sinks are also known by other names, like ceramic or vitreous china.
- Crushed glass: Trendy right now, crushed glass can make an impact statement. Usually this glass is tempered for daily use.
- Stone: Vessel sinks made from natural stone like granite or quartz can be heavy but durable. They are also generally more expensive than other types of sinks.
- Concrete: A concrete sink is a more unusual but fashionable choice. This type of sink requires professional installation. If it cracks, replacement is the only option.
- Plastic: Affordable and light to install, a plastic sink is more for function than fashion. The longevity of plastic is durable and can be easily cleaned.
- Stainless Steel: Much like with kitchen sinks, a stainless steel bathroom sink can make a huge statement and add a utilitarian look to your bathroom.
How to Replace an Undermount Bathroom Sink
Materials Needed:
- Silicone caulk
- Caulk gun
- Sink clips or brackets
- Drill
- Measuring tape
- Supports or helper
Step One: Measure the dimensions of your existing sink. Also measure the hole in the countertop. It's important you replace the damaged sink with one that matches the size of the hole in the countertop to avoid any uneven edges.
Step Two: After you remove the existing sink. take your caulking gun and apply a line of silicone caulk to the upper lip of your new sink. Be generous with the caulk, as this should create an airtight seal when it dries. You can remove any excess later.
Step Three: Working from below your counter, position your new undermount bathroom sink underneath the countertop. Line it up with the hole in the countertop and make sure the edges of the sink and the countertop hole are flush.
Lift up the sink until it presses tightly against the underside of the countertop. If you have a helper, have them hold the sink in place for next step. If you do not have a helper, position plywood supports underneath sink to hold it in place.
Step Four: Drill sink clips or brackets at even intervals around upper lip of undermount sink to attach them to underside of countertop. Be sure to use screws that are not too long and do not penetrate the whole way through the countertop. Use as many brackets as necessary to create a solid bracing system around the edge of the sink.
Step Five: Allow silicone caulking to dry. Remove supports. Scrape away any excess caulking that has dried, or sand down any edges that may stick out. Your new sink is ready to use.
