The answer to this question depends on what you consider to be a good double sink. Naturally, you want to have a sink that looks great, but is also highly functional. Also, it needs to be compatible with appliances such as the dishwasher and garbage disposal. Now, the prices on sinks vary; along with installation, this could set you back anything from $200 to $500. Of course, this is when we talk about standard models. There are always ridiculously expensive luxury sinks, but that’s probably not what you’re looking for.
