The standard size of a sink base is 33 inches. To allow your sink to be mounted, you need enough space for clips to attach to the countertop. While installation conditions can vary depending on sinks, you should allow for about 1/2 to 1-inch space between the sides of the sink to ensure it is properly installed.
Undermount sinks are installed underneath the counter. They will be sealed with silicone sealant to the countertop and then secured with clips to the countertop's underside. The clips require a very small space for installation. A standard 33-inch wide sink base can accommodate a 32" sink. You can consider buying a 24 inch sink from https://www.kralsu.com/pages/24-inch-kitchen-sink.
When measuring a sink, make sure you measure the entire sink. This means that you must look at the dimensions from the edge of the sink rim and not just the dimensions of the bowls. A 33-inch sink base cabinet will not accommodate a 32 1/2-inch sink without a custom cabinet.
Topmount sinks have a rim that sits on top of the countertop. The countertop is sealed with silicone or caulk. These sinks will come with ridges beneath that will be secured by clips. Topmount sinks will have the same rules as undermount. There must be at least 1/2 inch space between your sink's dimensions and your cabinet.
