But before you make the investment, you’re probably wondering: How much does it really cost to install an undersink water filter system?
In this comprehensive guide, we’ll dive into the typical costs associated with under-sink water filter installation as well as explore some alternative filtration options like benchtop and gravity systems. By the end, you’ll have a clear understanding of what to expect when upgrading your home’s water quality.

How much does it cost to install a water filter under a sink?

The total cost of installing an under sink water filter can vary quite a bit depending on several key factors. Let’s take a closer look at the individual components that contribute to the overall price tag.
The filtration system itself: The cost of the under sink water filter unit is typically the biggest expense. High-quality models from reputable brands can range anywhere from $300 to $700 or more. These systems usually include features like multi-stage filtration, long-lasting cartridges, and certifications for contaminant removal.
On the more affordable end, you can find basic under-sink filters for as little as $100. While these may not offer the same level of contaminant removal and performance, they can still provide an improvement in water quality.
Installation labour: Hiring a plumber to handle the physical installation of your best under-sink water filter is another significant cost to consider. Depending on your location and the plumber’s hourly rate, you can expect to pay anywhere from $100 to $300 or sometimes more for the labour.
It’s worth noting that some under-sink water filter models are designed for DIY installation, which can help you save on labour costs if you’re comfortable tackling the project yourself. However, it’s important to carefully follow the manufacturer’s instructions and ensure a proper, leak-free setup.
Additional materials and supplies: Beyond the filtration system and installation labor, you may also need to account for a few extra materials, such as wrenches and thread seal tape.

Putting it all together, a complete under sink water filter installation, including a mid-range system and professional labor, can range from $400 to $900 or more. Of course, the final price will depend on the specific product you choose and the complexity of the installation in your kitchen.

Do plumbers install water filters?

Yes, most plumbers are well-equipped to handle the installation of under sink water filters as well as residential reverse osmosis systems.
Plumbers have the necessary expertise and tools to properly connect the water filter to your sink’s plumbing, ensuring a secure and leak-free setup. They can also provide guidance on selecting the right filtration system for your needs and your home’s water quality.

In addition to under sink filters, plumbers can also install:

Water filter for bore water, tank water, or river water: If your home relies on a private well or bore water source, a specialized water filter can be installed to remove contaminants and ensure the water is safe for drinking, cooking, and household use.
Reverse osmosis (RO) filters: These advanced under sink filtration systems use the process of reverse osmosis to remove dissolved solids, heavy metals, and other contaminants from your water, delivering exceptionally pure H2O.
Whole-home water filter systems: For comprehensive water quality improvement, some plumbers can install whole-house water filters that treat all the water entering your home, ensuring clean water for every tap and appliance.
When working with a plumber to install an under sink water filter or any other residential filtration system, be sure to ask about their experience, credentials, and warranty coverage. A qualified professional will ensure the job is done right the first time, giving you peace of mind and clean, safe water for years to come.

Choosing the Right Under Sink Water Filter System

Now that you have a better understanding of the typical costs involved, it’s time to start exploring your under sink water filter options. Remember, the quality of the filtration system and the complexity of the installation will have the biggest impact on the final price tag.
For a budget-friendly solution, a basic under sink water filter system can be a great choice. These entry-level models often use a best single-stage activated carbon filter to remove chlorine, sediment, and common contaminants, providing a noticeable improvement in water taste and clarity.

If you’re looking for more comprehensive filtration, consider an under sink water filter system with multiple stages, such as sediment pre-filtration, activated carbon, and even reverse osmosis technology. While these top-of-the-line models come with a higher price tag, they can effectively remove a wider range of contaminants, including lead, heavy metals, and difficult-to-filter compounds.

Alternatively, benchtop water filters or gravity water filter can offer a convenient solution that doesn’t require any permanent plumbing modifications. These countertop filtration options can be a great choice for renters or those who prefer a more portable solution.
Regardless of which under sink water filter or alternative filtration system you ultimately choose, the key is to do your research, compare features and specs, and work with a trusted plumber to ensure a seamless and cost-effective installation. With the right filtration solution in place, you can enjoy the peace of mind of having clean, great-tasting water flowing from your kitchen sink.
