Most people would agree that having a utility sink in your garage is handy for several reasons. You could find a sink helpful for cleaning up after a painting project, keeping your vehicle spotless, maintaining your garden tools, or just having an extra wash-off station outside your clean home. But what if you don’t have a plumbing hookup in your garage? Can you still install a utility sink? It’s possible, but there are a few plumbing considerations. Learn more about how to add a utility sink in the garage without existing plumbing.
How Can You Add a Utility Sink Without Plumbing?
If you don’t have existing plumbing connections inside your garage, you have two options for installing a utility sink: Install plumbing connections or install a portable sink.
To add plumbing to your garage, a professional plumber must run water and sewer lines to your home’s existing plumbing systems.
Alternatively, you may consider adding a portable sink if you don’t want to commit to installing plumbing. If you plan to use your sink less frequently or have limited space in your garage, this may be a better option since it’s entirely portable. The downside is frequently having to refill and empty your supply and waste tanks.
Things To Consider Before Adding a Utility Sink in the Garage
Before you consider plumbing a utility sink in a garage, consider these additional facets of selecting the right type of sink, installation procedures, and other long-term factors:
- Plumbing codes. Before adding any plumbing to your home, checking your local plumbing codes should be your priority. Violating these codes can have severe consequences for your health and the safety of your home. That’s why having a professional plumber is always recommended for new or replacement plumbing installations.
- Heating. Pipes will likely freeze in colder climates without proper heating or insulation. This means that your garage—which likely has no heat or insulation—is a higher risk zone for this issue. Consider adding insulation if your pipes are exposed.
- Installation interruptions. Depending on how far your interior water pipes are from your unplumbed garage, installation may be more or less invasive to your day-to-day. While your piping may be installed through the wall, your drainage must go through the floor and that means cutting through concrete.
- Sink type. There are several types of utility sinks to select from, and choosing the right fit for your available space and its intended use may be a challenge. Size, drainage, durability, capacity, and more play significant roles in the long-term use of your utility sink. Consult with a professional plumber for selection advice and reliable sink installation services.
- Faucet type. Similar to selecting your sink type, finding the right faucet for your needs has just as many considerations. Various features such as material, detachability, dual-spray, and more can be beneficial for different types of uses. Count on your nearby plumbing expert for faucet installation and selection services.
