What Are The Advantages of Top Mount Kitchen Sinks

What type of kitchen sink do you have? It may be a porcelain sink, granite or composite sink, but these are the materials that constitute the sink. We are inquiring about the mounting style. Any kitchen sink has a distinct style of mounting. Broadly speaking, the installation can be of two types – drop-in or undermount. 

The drop-in or top-mount sinks are the ones that drop into the pre-cut hole on your kitchen countertop. The name itself is quite self-explanatory. The rim of the sink sits visibly on the countertop and supports the weight of the sink, irrespective of the sink’s size, weight, material, and style. It is a highly sought-after style of a kitchen installation for granite and composite countertops that are structurally sound enough to support the sink’s weight.

Why do we still love top-mount sinks?

There was once a time when all you could find were top-mount sinks. From delicate porcelain designs to sturdy and bold cast iron, every sink was top-mount only. However, undermount sinks soon took over the market since this style of installation is almost seamless. The rim of the sink sits under the countertop making the edges invisible, and it adds panache to the kitchen counter.

That might make you wonder how the self-rimming sinks have survived this long. 27 inch undermount sink are clearly better-looking and more appealing to the sophisticated customer, so what makes drop-in sinks the highest-sellers among all kitchen sinks?
