Cost to Install a Laundry Sink
Installing a laundry sink means fitting a basin, faucet, and drain assembly, then tying water supply lines and PVC drain piping into the existing laundry plumbing. The work is moderate because the basin must fit the space and the new water and drain/vent connections must be compatible, watertight, and properly vented.
Common reasons homeowners do this job
- Replacing a worn or damaged laundry sink
- Adding a utility basin for washing up or handling laundry tasks
- Upgrading a laundry area during a remodel
- Creating a more useful work area near existing water and drain lines
DIY or call a pro?
This can be a DIY project for someone comfortable installing a faucet and drain assembly and connecting water supply lines, PVC piping, and the existing drain/vent system. Consider a professional if there is uncertainty about the existing plumbing compatibility or the drain and vent connection. Turn off the laundry-area water supply before starting, confirm nearby outlets are GFCI protected, and make sure drain connections are properly vented. Check with your local building department whether this work needs a permit.
Frequently asked questions
- Can I install a laundry sink myself, or should I hire someone?
- A homeowner can take this on with an adjustable wrench, PVC pipe saw, level, bucket, slip-joint pliers, and channel-lock pliers. It is a moderate project, so professional help is worth considering when connecting to the existing drain/vent system or confirming that existing water and drain lines are compatible.
- What makes the price of a laundry sink installation go up?
- The price can increase with the job's size and number of sink, labor time, the selected basin, faucet, drain assembly, piping, fittings, and supply lines, plus removal of old material. A small job may also include a minimum or trip charge.
- What should I check before buying a laundry sink basin?
- Start by measuring the available space and identifying a location near existing water supply and drain lines. Before purchasing, confirm that the basin fits and that the existing plumbing can be connected to the new faucet and drain setup.
- How can I avoid leaks or drain problems after installing a laundry sink?
- Install the faucet and drain assembly on the basin before securing the sink, then test every water and drain connection for leaks before finalizing the work. Keep a bucket ready, shut off the water supply first, and vent the drain connection properly, since improper venting can allow sewer gas leaks.
