Love Cooking? How to Install a Dishwasher-Friendly Double Sink

Does your tiny single sink limit your culinary creativity? Are you tired of washing a mountain of pots and pans by hand? Installing a double kitchen sink can make cooking and cleaning a breeze - especially when you add a convenient dishwasher hookup into the mix.

With ample basin space for food prep and immersing large cookware, plus built-in drainage for your dishwasher, a double sink streamlines workflow.

Choosing Complementary Sinks and Faucets

The first step in creating your ideal kitchen is picking out aesthetically pleasing sinks and faucets that also suit your needs.

Sink Options for Serious Cooks

When selecting a double kitchen sink, consider the following:

• Size - Standard double bowl sinks are about 33" wide, but larger options are available if you have the space.
• Depth - Deeper basins (10"+) easily fit large pots and platters.
• Materials - Stainless steel is durable and matches most kitchens. Enamel and composite sinks offer more color options.
• Installation - Undermount for a seamless countertop look or top-mount for easy DIY.
• Coordinating finishes - Match sink and faucet metals like brushed nickel or chrome.

Choosing Faucets for Functionality

Don't forget the faucet - it should excel at filling pots as well as looking sleek. Consider configurations like:

• Bridge vs. widespread - Bridge styles mount over both basins on a horizontal bar. Widespread has separated hot/cold handles.
• Hands-free options like motion sensors or touch-control activation.
• Additions like a pull-down sprayer or commercial-style spray faucet.
• Single-handle vs. double-handle - Double offers more precise temperature control.
• Finishes to match your sink and kitchen decor.

Planning Your Installation

Careful planning ensures your double sink and dishwasher can be integrated seamlessly. First, inspect under the existing sink and make note of the plumbing layout. Measure to ensure your chosen sink and dishwasher will fit the existing space.

Mapping Out Plumbing and Drainage

Create a detailed plan for installing supply lines, drain lines, and dishwasher hookup components like an air gap. Consider:

• Drain line routes from each sink basin and dishwasher to main drain
• Supply line placement for sink faucet and dishwasher hookup
• Space for garbage disposal if desired
• Optimal dishwasher location within the cabinetry

Assembling Necessary Materials

Before starting, gather all the key plumbing supplies you'll need:

• Chosen sink, faucet, drain baskets, and tailpieces
• P-traps, pipes, compression fittings, and dishwasher hookup kit
• Wrenches, bucket, tubing cutter, hacksaw, and emery cloth
• Teflon tape, caulk, and plumber's putty for watertight seals

Step-by-Step Installation Guide

Once you've planned everything out and have materials ready, it's time to dive into the installation. Follow these steps to integrate your double sink and dishwasher properly.

Securing the Sink Basins

First, make precise countertop cutouts following your sink's dimensions. Test fit the sink to ensure it aligns correctly before permanently securing it.

• For undermount sinks, attach with mounting brackets or adhesive.
• Seal the edges with waterproof caulk or sealant.
• For top-mount sinks, set in place and seal the countertop contact area.

Installing the Drain Assembly

Next, assemble the drainage starting at each sink basin.

• Attach tailpieces, P-traps, and waste tee to outlet holes.
• Slope pipes 1/4" per foot and support with hangers.
• Connect drains together then to the main sink drain line.

Attaching the Water Supply

Connecting the faucet supply lines comes next:

• Link hot and cold faucet handles to supply lines and angle stops.
• Clearly label hot vs. cold lines.
• Use compression fittings for straightforward assembly.

Integrating the Dishwasher

Finally, seamlessly incorporate the dishwasher:

• Install air gap fitting near sink rim.
• Attach drain hose from dishwasher to air gap inlet.
• Run outlet hose from air gap to disposal or sink drain pipe.
• Connect dishwasher supply line to hot water line via shutoff valve.

Applying Finishing Touches

Double check all joints and connections then make any final adjustments:

• Caulk around sink to seal it to the countertop.
• Test for leaks and tighten any areas that drip.
• Add accessories like filtered faucet, soap dispenser.
• Clean and sanitize the sink before first use.

Proper ongoing maintenance keeps your sinks and dishwasher running smoothly for years. Follow these tips to prevent problems:

• Ensure drain lines have adequate venting to prevent clogs.
• Use slip-joint fittings for easy repairs and modifications.
• Frequently clean disposals, baskets, and dishwasher filters.
• Watch for sluggish drainage as a clue to clogs.
• Install whole-house water filtration to reduce sink and dishwasher mineral buildup.
