According to a recent home improvement survey by Thumbtack, homeowners are increasingly investing in backyard upgrades. If Instagram is any indication, much of this interest centers around the concept of stock tank pools (check out #stocktankpools to see what we mean). It’s an option some aspiring pool owners consider more affordable and accessible but just as much fun as a traditional swimming pool.

Understanding Stock Tanks and Their Growing Popularity

A stock tank pool is exactly what the name implies—a pool made out of a stock tank, AKA a large galvanized metal tub.

What are stock tanks originally used for?

Stock tanks are the same metal tubs that farmers use to water livestock.

Stock tanks are typically 24 inches deep. They are available in diameters from two feet all the way to 10 feet, but the eight-foot model is popular for pools. This size holds about 800 gallons of water. These tanks are made of galvanized steel for durability or sometimes heavy-duty plastic (polyethylene). Their robust construction, designed to withstand farm use and outdoor elements, makes them a sturdy candidate for repurposing. Fun fact, in Texas, these tanks are used for cows and emus.

Having trouble getting past the fact that this is an animal watering trough? Rest assured: Part of the appeal of stock tank pools is that they allow for lots of design versatility. Even though they are watering troughs, they don’t necessarily look like water troughs once everything is said and done.

Why are stock tanks ideal for DIY pools?

The primary appeal of stock tanks as DIY pools lies in their relative affordability and simpler setup compared to conventional pools. They offer a rustic chic aesthetic and their compact size makes them suitable for small backyards. Many enjoy the versatility in design, which allows for a range of styles from a simple standalone tank to one integrated into a deck or surrounded by landscaping.

Stock Tank Pools Pros and Cons

Is a stock tank pool a good choice for your family? Here are the pros and cons.

The pros of stock tank pools:

  • Stock tank pools are less expensive than many other types of pools. The cost of an in-ground pool, for example, starts at around $25,000. Stock tank pools cost a fraction of that.
  • While cleaning and maintenance are required, it’s straightforward and doesn’t take a ton of time, especially if you clean regularly. If you are familiar with cleaning in-ground or other above-ground pools, cleaning a stock tank pool will feel like a piece of cake.
  • Once you have the supplies and equipment, a stock tank pool can be set up quickly.
  • They’re sturdy and stand up well to the elements.
  • You can warm the water with a heat pump.

The cons of stock tank pools:

  • Demand can be high. Likewise, supply is low. This means procuring a tank and all the associated supplies can be challenging.
  • Standing water is a breeding ground for mosquitoes and other bugs. If you don’t properly maintain your pool, this will become a problem.
  • While installation and set-up is doable for a moderately handy DIYer, it is nearly impossible to haul stock tank pools on your own. Larger stock tanks sometimes require wide load permits and specialized trailers.
  • This isn’t a con so much as something to be aware of—stock tank pools do require chlorine. We recommend using two chlorine tablets each week to keep the water clean. Unfortunately, some parts of the U.S. are experiencing chlorine shortages, thanks to recent mishaps at chlorine plants in Louisiana and Washington state. This could hinder you from staying on schedule with the tablets.
  • While they are easy to drain (simply remove the drain plug), you’ll need to pay attention to where the water goes so it doesn’t over-saturate nearby landscaping or flood your basement.
  • You can’t just place them anywhere. Stock tank pools belong on concrete or other level surfaces that are not riddled with rocks, sticks, dirt, etc.

How to Choose the Right Stock Tank for Your Pool

DIY stock tank pools come primarily in galvanized steel, or lighter plastic versions.You can pick either one of these based on whether you want a semi-permanent pool or a temporary, summertime installation for the kids. For small families, round tanks measuring 24 inches deep with 8-foot diameters (holding 700-800 gallons) are ideal.

Prices usually range from $150 for small 3-foot tanks to $500-$700 for larger 8-10 foot options at agricultural suppliers like Tractor Supply Co. Also, consider transportation logistics, as larger tanks require trucks or trailers and availability may fluctuate seasonally.

Guide to Creating a Stock Tank Pool

A DIY stock tank pool requires proper preparation beyond just filling with water. Start by selecting a completely level location free of debris, creating a solid foundation that can support 6,500+ pounds of water weight and planning for drainage away from structures.

For effective stock tank pool maintenance, install a pump and filter system. Choose an appropriate pump, carefully create sealed connections in the tank and ensure electrical safety with GFCI outlets.

Personalize your DIY stock tank pool by painting it, building a bench around the pool, landscaping around it, and either creating a beachy vibe with sand and chaise lounges or go for a fun, party vibe with fairy lights and a mini bar.

Maintenance for Stock Tank Pools

With proper stock tank pool maintenance, you can enjoy safe swimming. Run your filtration system daily, using chlorine tablets in floating dispensers while regularly testing water chemistry. Consider alternative sanitizers carefully, as salt systems may accelerate corrosion on galvanized metal tanks.

Regularly skim debris and periodically drain and refill the pool. For galvanized steel tanks, prevent rust by maintaining proper water chemistry, avoiding abrasive cleaners and potentially applying rust-inhibiting coatings. Common issues include leaks around pump fittings (requiring proper sealant), mosquito breeding (prevented by filtration and chlorination) and hot metal edges (mitigated with pool noodle padding).

Are Stock Tank Pools Safe?

As with any pool, safety is most important. While stock tank pools are not inherently unsafe, there are a few important safety-related things to keep in mind.

  • If you choose to use a pump to heat your pool, remember that a heat pump involves horsepower and electricity. Improper installation or mishandling is dangerous and can lead to electrocution. As always, call an electrician if you have any qualms about your ability to safely install a heat pump.
  • People with children or pets should install two layers of security around the pool (a pool cover and a locked gate, for example) because drowning is still a risk, even in such shallow water.
  • Concerned that the metal will cause the water to become dangerously hot, or that hot weather will do the same to the metal pool itself? Don’t worry, any part of the pool in contact with water will remain cool to the touch. And because water takes so long to heat up, it’s unlikely it will ever get hot enough to burn your skin.
  • As for the parts of the pool that are not in direct contact with water, they usually stay cool enough to the touch as well. You can always cover the top edge with a pool noodle that has been cut in half with a serrated knife just to be sure.
  • As with any pool, it’s always a good idea to watch your step as you get in or out so you don’t slip. And no diving—remember, it’s shallow!

Are Stock Tank Pools Expensive?

Stock tanks are more affordable than traditional pools.

    • Basic DIY (no pump): A tank ($150-$700+) and chlorine supplies ($80+) could be under $1,000 assuming you can transport and place the tank yourself.
    • DIY with pump/filter: Adding a filter pump ($100-$300+) and plumbing parts ($50-$100+) increases the cost.
    • Pre-assembled kits/professional installation: Companies specializing in stock tank pools may offer packages including the tank pump filter plumbing and sometimes delivery/setup. These can range from around $1,500 to $4,000+, depending on size, features, and your location.
    • Overall, a DIY stock tank pool can be a significantly cheaper way to get a backyard pool but costs can escalate with added features and professional help.
