Adding another sink to your bathroom can significantly improve its functionality and value. Whether you're looking to create a his-and-hers vanity, accommodate a larger family, or simply want to increase counter space, this guide will walk you through the process of installing an additional sink, from planning to execution.
Planning Your Additional Sink
Before you start any work, it's crucial to plan your new sink installation carefully.
- Measure your space: Ensure there's enough room for the new sink, faucet, and cabinet or countertop. The typical minimum distance between two sinks is 36 inches.
- Choose your sink: Select a sink style and size that fits your space and complements your bathroom decor. Consider undermount, drop-in, or vessel sinks, and opt for single or double-bowl designs.
- Check plumbing: Verify if your bathroom's plumbing can accommodate another sink. You may need to install new pipes or connect to existing ones.
- Permits and codes: Check local building codes and obtain any necessary permits before starting work.

Installing the Plumbing
Before installing the sink, you'll need to connect the plumbing. If you're not comfortable working with pipes, consider hiring a professional plumber.
- Turn off the water supply and drain the existing pipes.
- Connect new pipes to the main water supply and drain lines, using appropriate connectors and teflon tape to prevent leaks.
- Run the new pipes to the location of your additional sink, ensuring they're securely fastened and properly sloped for drainage.
- Test the connections for leaks, then turn the water supply back on.
Installing the Sink and Countertop
Now that the plumbing is in place, it's time to install the sink and countertop:
- Measure and cut the countertop or cabinet to fit the new sink location, using a saw if necessary.
- Apply construction adhesive to the underside of the countertop or cabinet, then secure it in place with screws or brackets.
- Position the sink in the cutout, ensuring it's level and centered. Mark the drilling locations for the faucet and drain.
- Drill holes for the faucet and drain, using a drill bit slightly smaller than the faucet's mounting hardware.
- Install the sink according to the manufacturer's instructions, using putty or silicone to seal the underside if necessary.
- Attach the faucet and drain assembly, following the manufacturer's guidelines.
Finishing Touches
With the sink and plumbing installed, complete your project with these final steps:
- Caulk: Apply caulk around the sink and countertop edges to create a watertight seal.
- Grout: If you've installed a tile countertop or backsplash, apply grout between the tiles to fill the joints.
- Test: Run water through the new sink to ensure it drains properly and there are no leaks.
Congratulations! You've successfully added another sink to your bathroom. By following these steps and taking the time to plan and execute your project carefully, you'll enjoy the benefits of your new sink for years to come.
