Common reasons to replace a kitchen sink are due to damage, to boost home value, or to improve your lifestyle. Kitchen sinks that are constantly leaking, clogging, or pooling typically result in frequent repairs that can ultimately cost more than the price of a new sink. New, modern kitchen sinks can also boost your home’s value when it comes time to resell, and installing a new, larger sink can make your life easier when it comes time to do the dishes or host a get-together.
