The Best Outdoor Water Softeners for Any Home

Fact checked by Stephen Conklin

best outdoor water softener

Any household with a hard water supply knows the struggle that comes with it. The minerals in your water may not be toxic, but they can cause scaling in your plumbing, showerheads, and faucets. Besides, it affects your skin and hair health.

Getting rid of the elements that are making your water hard is the solution to all these problems. What you need is the best outdoor water softener. It can remove not only the hardness but also improve the quality of your water.

When choosing a unit to purchase, there are several things that you should consider. These factors can either make or break your choice and determine whether you get a suitable system for your household. Here we have three elements:

  • Climate

The ideal climate for an outside water softener does not drop below freezing during the cold months and doesn’t get too hot during the summer. However, it doesn’t mean that you can’t have a water softener when the weather in your area is unpredictable. It is necessary to find a unit that operates well in your climate. Contact a local expert and ask for their opinion.

  • Capacity

Not all water softener units have the same grain capacity since it varies depending on the brand and model. This way, people are not limited to only a single capacity system.

Deciding on the capacity will depend on the water usage of a household. The bigger is better principle does not apply to this one. Do not buy a larger unit just because you can because this will do more harm than good.

  • Locality

If possible, buy your water softener from local stores. They know the local water supply, so they can help you find the optimal unit for your home. You can also inquire and learn more to operate the system efficiently.

These are only a peek of the complete list that we have in this article. There are several others that you should add to your checklist. But before that, take a look at these product reviews to get a general idea of what units are available in the market.

What to Look for When Buying Outdoor Water Softener


A suitable water softener unit does not only do an excellent job in drawing minerals out of your water supply. There are other factors that one should consider before making a purchase.

It could be a daunting process but not impossible. By understanding your needs and matching them with the things we have listed below, you can make an informed decision.

Build Quality

It is crucial to have an outdoor water softener unit with a strong build quality. There are many elements that they should weather through. Make sure that the one you are eyeing is specially designed to be situated outside. Otherwise, you will be left with a damaged water softener in a matter of months.


Opt for a system with parts that are easily accessible and replaceable. This will make it hassle-free to buy replacements from local hardware stores. It will do you a great deal of favor and prevent you from buying an entirely new unit that costs more than purchasing replacement parts.


When looking at brands, check for their credibility by knowing how long they have been in the market. It will be proof of how many people believed in their products. In addition, older brands tend to be more reliable since they’ve been producing water softeners longer.

You can expect their current products to be better after years of continuous improvement. But there are also newer brands that deliver high-quality units. It is crucial to decide after analyzing between brands.


When setting up a water softener outside, make sure that the climate doesn’t drop below freezing or is too hot. If your local weather is not suited for installing a unit outside, you can always pick an area with a shade or bury it underground. Talk with your local hardware stores to see which system is the best for your household, considering how varied the weather can be.

Cover and Enclosure

In addition to the previous factor, an outdoor water softener enclosure works best in protecting your unit. This will ensure that whatever the weather outside is, your system is safe and sound. There are tons of options in the market depending on the type and quality; expect to spend between $50 to $150. Take into consideration the size of the unit before buying an enclosure or cover.

We covered some of the most critical and essential elements that you need to carefully consider before deciding on a water softener system. Take note of these, and the next time you go hunting for a unit that is best suited for your home, don’t forget to bring the list with you.

Can You Put a Water Softener Outside


Placing a water softener outside or in the garage is possible, but you expose it to dangerous environments. The majority of manufacturers designed their water softeners to be capable of bearing harsh elements. This allows the systems to survive and operate pretty well. But not all water softeners are made to endure such conditions.

Whether or not your unit can be placed outside will depend on its build quality. While it is possible to minimize its exposure to hazardous elements, it can only go as far as it allows. It is also your decision to risk installing your unit outdoors.

How Do I Protect My Outside Water Softener

An outdoor water softener is designed better to withstand the harsh environment outside your home. But one should not rely solely on this; thus, outdoor water softener cover is often purchased alongside the unit.

This can preserve the appliance from dust and debris. If you want to protect the system from the sunlight or the cold, a water softener for outside cabinets or housing is the best option. This will provide protection from hazardous weather.


The process of buying the best outdoor water softener involves a lot of research and contemplation. However, if you want to efficiently address your home’s hard water supply, it is necessary to find a high-quality unit that can cater to all the water problems you have.

Reading reviews and taking note of the crucial factors to consider can significantly increase your chances of landing a decent outdoor water softener system. In addition, you should include your preferences and water usage for a sound decision. We hope that with all the information we provided you, you can purchase a unit that is best suited for your household.
