How to Plumb a double vanity sink to one drain

Plumbing a double vanity sink to one drain is a common practice in bathrooms with limited space or for aesthetic reasons. Proper installation is crucial to ensure efficient drainage and prevent issues such as clogs or backups. In this detailed guide, our team of experts Local Plumber will provide step-by-step instructions on how to plumb a double vanity sink to one drain effectively, ensuring optimal performance and functionality.

Let’s understand the Double Vanity Sink concept

A double vanity sink, also known simply as a double sink vanity, is a bathroom fixture that features two separate sink basins set into a single countertop or vanity unit. This type of vanity is commonly found in master bathrooms or shared bathrooms where multiple users need access to sink space simultaneously.

Double vanity sinks offer several benefits, including:

Convenience:

With two sink basins, double vanity sinks allow multiple users to use the bathroom simultaneously, making it easier for couples or families to get ready in the morning without having to wait for their turn at the sink.

Increased Storage:

Double vanity sinks often come with ample storage space, including drawers, cabinets, or shelves, providing additional storage for toiletries, towels, and other bathroom essentials.

Enhanced Aesthetics:

Double vanity sinks can add a sense of symmetry and balance to the bathroom, creating a visually appealing focal point. They come in a variety of styles, materials, and finishes to complement any bathroom decor.

Functionality:

Double vanity sinks offer practical functionality, allowing users to have their own designated sink space for tasks such as washing hands, brushing teeth, or applying skincare products.

When installing a double vanity sink, it’s essential to consider factors such as plumbing requirements, available space, and desired features. Proper installation and maintenance are crucial to ensure the longevity and functionality of the double vanity sink in your bathroom.

Assessing the Plumbing Layout:

Before beginning the installation process, it’s essential to assess the existing plumbing layout and determine the feasibility of connecting both sinks to a single drain. Consider factors such as the location of the existing drain pipe, available space underneath the vanity, and any obstacles or obstructions that may affect the installation process.

Gather Necessary Materials and Tools:

Next, gather all the necessary materials and tools needed for the installation. This may include PVC pipes, fittings, drain assemblies, pipe wrenches, channel locks, hacksaw, PVC primer and cement, tape measure, level, and plumber’s putty. Ensure that all materials and tools are of high quality and suitable for the specific requirements of the installation.

Prepare the Workspace:

Clear out the area underneath the vanity and ensure that there is ample space to work comfortably. Place a drop cloth or towel on the floor to protect it from any spills or debris. Additionally, turn off the water supply to the bathroom and disconnect any existing plumbing fixtures or pipes that may interfere with the installation process.

Install the Drain Assembly:

Begin by installing the drain assembly for each sink basin. Start by applying plumber’s putty or silicone sealant to the underside of the drain flange and insert it into the drain opening in the sink basin. Secure the flange in place by tightening the retaining nut underneath the sink using channel locks or a basin wrench.

Connect the Drain Pipes:

Once the drain assemblies are installed in both sink basins, it’s time to connect the drain pipes. Measure and cut the PVC pipes to the appropriate lengths using a hacksaw, ensuring that they fit snugly between the drain assemblies and the main drain pipe. Use a tape measure and level to ensure accurate measurements and proper alignment of the pipes.

Dry Fit the PVC Pipes:

Before permanently attaching the PVC pipes, dry fit them together to ensure that they align correctly and allow for proper drainage. Make any necessary adjustments to the pipe lengths or angles as needed to achieve the desired configuration. Once satisfied with the fit, disassemble the pipes and proceed with the next steps.

Apply PVC Primer and Cement:

Using a brush, apply PVC primer to the outside of the pipe ends and inside of the fittings where they will be joined together. Allow the primer to dry for a few seconds, then apply PVC cement to the primed surfaces. Quickly insert the pipe ends into the fittings, ensuring a tight and secure connection. Hold the pipes and fittings in place for a few seconds to allow the cement to set.

Secure the Pipes:

Once the PVC pipes are cemented together, use pipe straps or hangers to secure them to the underside of the vanity or to nearby walls or studs. This will prevent the pipes from sagging or shifting over time and ensure proper drainage.

Test the Drainage:

After completing the installation, turn on the water supply to the bathroom and test the drainage system by running water in both sink basins simultaneously. Check for any leaks or drainage issues and make any necessary adjustments or repairs as needed.

Apply Caulk or Sealant:

Finally, apply a bead of silicone caulk or sealant around the edges of each sink basin where it meets the countertop to create a watertight seal. Smooth out the caulk with a damp cloth or finger to ensure a clean and professional-looking finish.
