There are several types of sink drain stoppers, including pull-out, twist-and-pull, and pop-up. Pull-out sink stoppers can be removed by pulling on the stopper until it comes out of the drain. A twist-and-pull design requires lifting then turning the stopper to lock it in an open position and the opposite action (turning, then pressing down) to close it. A pop-up sink stopper works by pushing down the drain cover to open or close the passageway. 

The standard kitchen sink size is typically 22 inches by 30 inches. However, kitchen sinks are available in a wide range of sizes to fit different kitchens, commonly from 25 to 39 inches long, though you can find even larger or custom sizes. When choosing a replacement, the easiest option is to select a sink that matches your existing one's dimensions. If you decide to install a larger sink, you will need to enlarge the cutout in your countertop; be sure to use the template that comes with the new sink to ensure a proper fit. Installing a smaller sink can be more complex, as it may require replacing the entire countertop.

Silicone caulk—despite having some adhesive properties—is not the primary thing that holds your sink in place. Rather, it seals the gaps around the sink to prevent water from leaking and causing issues with mold and corrosion. Most sinks are secured by clips, though some sinks are secured with two-part epoxy or brackets.

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.
