Choose the Perfect Double Kitchen Sink Size With This Complete Guide
With so many options for double kitchen sinks, it can be tricky to know where to start. Choosing the right size double sink for your space and needs is key to creating a functional, beautiful kitchen design.
What is a Double Kitchen Sink?
A double bowl kitchen sink has two basins side-by-side instead of the single basin of a standard sink. The two bowls are separated by a divider that can be either a low partition or a higher bar depending on the sink style.
Double sinks provide more versatility for kitchen tasks like washing produce, filling large pots, and soaking dirty dishes. The extra basin allows you to multitask and work more efficiently.
Standard Double Sink Dimensions
Though available in a range of sizes, the most common double kitchen sink dimensions are:
- 33" x 22" - Total width of 33 inches with two 16.5" basins
- 36" x 22" - Total width of 36 inches with two 18" basins
Standard sink depths are usually 7" to 10", while extra deep double sinks may range from 10" to 12" for each basin.
Optimal double sink length depends on your needs. Longer sinks allow more room for washing large pots and baking sheets. More compact lengths around 22" can fit smaller spaces while still offering two basins.
Minimum Cabinet Size for Double Sinks
Most double bowl sinks need a minimum 36-inch wide sink base cabinet. Standard sink base cabinets are only 34.5 inches wide, so double sinks generally require a custom-sized cabinet.
In terms of depth, aim for at least 24 inches from the wall for the cabinet depth. This provides room for the plumbing and garbage disposal installation.
Key Factors In Selecting a Double Sink
Kitchen Layout and Work Triangle
Take stock of your current kitchen layout and measure the available space for the sink during planning. Note any windows, walls, or appliances that will border the sink.
Also pay attention to the workflow between the sink and other key kitchen zones like the stove, fridge, and prep areas. Optimize the double sink size and location to support your kitchen's work triangle.
Kitchen Use and Workflow
How will your family utilize the kitchen? Busy cooks and bakers will appreciate a more spacious double basin sink. If you frequently wash produce while soaking pots, a medium divider allows visibility into both sides.
For filling and cleaning large stockpots, a longer double sink provides more room. Entertainment-focused kitchens can benefit from a smaller sink with more counter space.
Style and Design
Double sinks come in a sleek range of styles to match your kitchen aesthetic. Undermount sinks offer a seamless counter integration. Materials like stainless steel, enamel, composite, and fireclay each have their own visual appeal.
You'll also want to consider color and finish. For example, a satin nickel faucet can complement a brushed stainless sink finish nicely.
Planning for Installation
Sink Base Cabinet Considerations
Most double sink installations require building additional framing and support into the sink base cabinet. Work with an experienced kitchen contractor to ensure it can handle the weight.
Have the cabinet customized if needed to achieve the ideal 36-inch minimum width your double sink requires.
Countertop Cutout
Creating the correct sink cutout hole takes precision. An experienced countertop fabricator is recommended, as an imperfect cutout can lead to leaks and other issues down the road.
Plumbing Logistics
Make sure your plumber has clear access to route the drain lines, supply lines, and garbage disposal under the sink base cabinet. This is why having proper cabinet depth is so important.
Now that you're armed with the key double sink dimensions and factors to consider, you can confidently begin your selection process. Carefully measure your existing kitchen space before deciding.
Keep your family's workflows and habits in mind as you explore different sink sizes and layouts. With the right sized double kitchen sink, you can optimize both form and function in your kitchen design.
