What is the cost difference between an undermount and a drop-in sink cutout when having countertops fabricated in Saint John or Moncton, and which option is more popular with NB contractors?

Undermount sink cutouts typically cost $150-300 more than drop-in cutouts at fabricators in Saint John and Moncton, but undermount sinks have become the preferred choice for 70-80% of kitchen renovations in New Brunswick.

The cost difference comes from the additional fabrication work required for undermount installations. Drop-in sinks simply need a hole cut to template specifications — straightforward and quick. Undermount sinks require the fabricator to polish the cut edge to a finished quality since it will be visible, plus they need to drill holes for the mounting clips that secure the sink to the countertop from below. This extra finishing work adds 2-3 hours of labour at most Moncton and Saint John fabrication shops.

Quartz countertops handle both installation methods well, but undermount is particularly popular because the seamless transition from countertop to sink makes cleanup easier — no rim to catch crumbs or water. Granite countertops also work excellently with undermount sinks, though the natural stone requires careful templating to ensure the sink fits perfectly. Laminate countertops cannot support undermount sinks due to the exposed particle board core, so drop-in is the only option.

Most NB contractors now recommend undermount sinks for several practical reasons beyond aesthetics. The seamless design prevents water from getting trapped around the sink rim — important in New Brunswick's humid summers when moisture can lead to mold or cabinet damage. Cleaning is significantly easier since you can wipe debris directly from the counter into the sink without navigating around a raised rim. The undermount style also makes the countertop appear larger and more continuous, which helps smaller NB kitchens feel more spacious.

Installation considerations favor undermount sinks in new renovations. The sink gets mounted to the countertop at the fabrication shop, then the entire assembly is installed as one unit. This creates a stronger, more permanent installation than trying to retrofit an undermount sink later. Drop-in sinks can be replaced by homeowners if needed, while undermount sinks require countertop removal for replacement.

For budget-conscious renovations, the $150-300 additional cost for undermount fabrication is usually worthwhile given the improved functionality and resale value. However, if you're keeping existing laminate countertops and just replacing the sink, drop-in remains your only option. Most Saint John and Moncton fabricators can complete either cutout style within their standard 3-6 week lead time for template-to-installation.
