The Ultimate Guide to Upgrading from a Double to a Single Bowl Sink

For years, double bowl sinks were seen as the “practical” choice—one side for washing, the other for rinsing. But as kitchens have evolved, so have the demands on sinks. More and more homeowners are discovering that a single bowl sink often does the job better, especially when it comes to modern lifestyles and large cookware. If you’re considering making the switch, here’s your ultimate guide to upgrading from a double to a single bowl sink.

The biggest reason for upgrading is space. A single bowl sink eliminates the center divider, giving you one large, uninterrupted basin. This makes it far easier to wash roasting pans, baking sheets, and oversized pots without awkward angles. Instead of struggling to maneuver dishes between two small compartments, you gain freedom and flexibility. For families and avid cooks, this alone can be a game-changer.

Upgrading also means streamlined cleaning. Double sinks often lead to messy habits, with dirty dishes piled in one bowl while the other is barely usable. A single bowl simplifies the process: everything goes into one basin, and cleanup becomes more efficient. Add in accessories like roll-up drying racks, colanders, and cutting boards, and your single sink can multitask just as effectively as a double—without the clutter.

The installation process requires some planning. If you’re replacing a drop-in double bowl sink with a single bowl, you’ll need to measure carefully to ensure your new sink fits the existing cutout. In some cases, adjustments to the countertop opening or plumbing layout are necessary. For undermount sinks, a proper seal is critical to prevent leaks. Working with professionals ensures the transition is smooth and avoids damage to your counters.

There are also design benefits to consider. Single bowl sinks come in a wide variety of materials and styles—stainless steel, fireclay, granite composite, and more. Their clean, open look pairs beautifully with modern kitchens, farmhouse designs, or even transitional spaces. By upgrading, you’re not just improving function—you’re also giving your kitchen a sleek, updated centerpiece.

At I Hate My Sink, we specialize in helping homeowners decide when it’s time to ditch the divider. For many, upgrading to a single bowl sink is less about losing something and more about gaining space, efficiency, and peace of mind. If you’re tired of fighting with your double bowl, it might be time to make the switch—and finally enjoy a sink that works as hard as you do.
