While the drain connection for a garbage disposal is nearly universal and fits standard sink drain holes of 3 1/2 to 4 inches, the size of the disposal unit itself is not. You must have enough space in the cabinet underneath your sink to accommodate the disposal's housing. A larger model may not fit in a compact cabinet or if the existing plumbing is arranged in an unusual way. Before buying a new garbage disposal, measure the available space under your sink. If you are replacing an old unit, it's often easiest to choose a new model of a similar size.

You’ll only need to replace your sink’s pipes when you start to notice signs of wear like corrosion or leaking. Most pipes last somewhere between 20 and 100 years, depending on the material. Copper and cast iron can last up to 100 years. Galvanized steel and brass generally have a 50-year lifespan. PVC pipes last 25 to 40 years.

Yes, it is often possible to replace an undermount sink without removing the countertop, but success can depend on the countertop material. For materials like granite, the process is relatively straightforward. However, laminate or uniquely shaped countertops might need to be removed or modified.

The process typically involves shutting off the water supply, disconnecting the drain and plumbing pipes, cutting through the old silicone seal, and carefully lowering the sink from below. This requires a good understanding of plumbing and the right tools. If you are not confident in performing the replacement yourself, it is recommended to hire a countertop specialist or a plumber to handle the task.

When installing an undermount kitchen sink in a granite countertop, use 100% silicone to secure the basin. If you’re worried your sink is too heavy, speak with a countertop professional about how to adhere the sink to the countertop without worrying about issues down the road. Sagging undermount sinks can be a common plumbing problem if they’re not properly adhered, so always make sure you’re using a high-quality material.
