Installing a new sink can really update the look and feel of your kitchen. Many homeowners opt for an undermount sink with their quartz countertops for a seamless, modern aesthetic. However, rimmed or drop-in sinks are still a popular choice. So can you install a rimmed sink with quartz countertops?
The short answer is yes, a rimmed sink can be mounted on quartz. However, there are a few things to keep in mind to ensure proper installation and functionality.
How Rimmed Sinks Work
A rimmed or drop-in sink sits on top of the countertop with its outer rim resting on the surface. The sink is lowered into a pre-cut opening in the countertop so that the rim overlaps the edges of the hole. The sink is then sealed to the countertop with silicone caulk or adhesive.
Benefits of Rimmed Sinks
Rimmed sinks have remained popular in many kitchens because they offer a few advantages:
- Lower cost – Rimmed sinks are often less expensive than undermount sinks.
- Ease of installation – Installing a rimmed sink does not require specialized skills or accessories.
- Flexibility – A rimmed sink can usually be installed with any countertop material.
- Repairability – The seal around a rimmed sink can be easily re-caulked if needed. With an undermount sink, the whole sink may need replacement if the seal fails.
Considerations for Quartz Countertops
Quartz makes an excellent countertop for kitchens and baths. It’s durable, attractive, and low-maintenance. However, there are a few factors to consider when installing a rimmed sink with quartz:
Cutout Size
- The cutout for the sink needs to precisely match the dimensions of the sink. Quartz is not as forgiving as other materials when it comes to adjustments during installation.
- Allow a very small (1/8 inch or less) reveal around the sink rim. Too large of a reveal can lead to cracks or chips in the quartz over time.
Support
- Rimmed sinks need full support underneath, usually from the cabinet or a frame. Any gaps or lack of support can cause the sink and countertop to sag or crack.
- The sink should also be level and well-secured to prevent movement that could damage the quartz.
Sealing
- Use a high-quality silicone caulk to seal the sink rim to the quartz. The seal prevents moisture damage.
- Take care not to get caulk on the visible quartz surface, as it can leave permanent marks.
- Re-seal as needed over time. Seal failure is a common cause of water damage with rimmed sinks.
Installation Tips
Follow these best practices for safely installing a rimmed sink in quartz:
- Carefully measure and cut out the sink opening in the quartz according to the specifications.
- Set the sink in place and check for level. Add shims if needed to stabilize.
- Drill pilot holes and secure the sink with mounting brackets, screws, and/or clips.
- Apply painter’s tape around the sink opening to protect the quartz surface.
- Thoroughly clean and dry the sink rim and quartz surface.
- Apply silicone caulk around the sink rim, smooth with a plastic spreader, and immediately remove the painter’s tape before caulk dries.
- Allow the caulk to fully cure for 24-48 hours before using the sink.
FAQs
Can any rimmed sink be used with quartz countertops?
Most standard rimmed sink models can work with quartz countertops as long as you follow the manufacturer’s instructions. Very heavy cast iron or stone sinks may require extra support.
What’s the best way to cut the sink opening in quartz?
It’s best to have quartz countertops professionally fabricated and installed. The fabricator has the tools and expertise to cut the sink opening smoothly and precisely.
Should I caulk the sink myself or have a contractor do it?
Caulking a sink is generally a DIY-friendly task. Use a high quality kitchen and bath caulk and take your time applying a smooth, consistent bead. Remove any excess before it dries.
How can I prevent cracking around the sink rim?
To prevent cracks, ensure the opening is cut properly, allow a very small reveal, secure the sink firmly to the countertop and cabinet, and use flexible caulk to absorb movement and vibration. Avoid excessive force on the sink rim.
How often should the sink be re-sealed?
Inspect the caulk seal periodically and re-apply fresh caulk if you see any gaps, cracks, or deterioration. Many pros recommend re-sealing about every 1-2 years as preventive maintenance.
Conclusion
Installing a beautiful rimmed sink can absolutely be done with quartz countertops. Pay close attention to the prep work, cutout size, secure mounting, and quality caulking to create a long-lasting, high-functioning installation. With care and proper installation, you can enjoy the classic styling of a rimmed sink combined with the durability and beauty of quartz.
