Integral sinks are made from the same material as the countertop they are set into. The effect is the seamless appearance of a smooth transition from sink to surface. In recent years, the integral sink has presented an opportunity for creative expression and personalized design in the installation of a common sink. There are both benefits and limiting factors to having an integral sink. The price of an integral sink can be expected to be hundreds of dollars more so the personal pros and cons should be considered. There are a limited number of materials that an integral sink may be constructed from due to the required versatility of the material to function as both water resistant sink and serviceable countertop. The lack of a seam between the sink and countertop does make cleaning significantly easier. A primary factor that must be considered when choosing an integral sink is that the two are permanently joined and should be treated as a single unit. Therefore, if the sink or countertop is damaged or replaced, the other piece must also be replaced.
