Choosing among the best stock tank pools comes down to how much water you want to manage, how much room you have, and whether the tank is actually shaped for lounging. My leading pick is the Behlen Country FarmFlex 8 ft × 2 ft for buyers who want a roomy round basin; the Rubbermaid BRUTE 50-gallon tank is the easier-to-drain compact option; and the Behlen FarmFlex 6 ft × 2 ft offers a middle ground for smaller yards. These are livestock and utility tanks, though, not purpose-built swimming pools. Their listed features do not establish pool-specific fittings, filtration compatibility, or human-use certification, so buyers should check those details before filling one for regular swimming.

The main tradeoff is capacity versus upkeep. The Behlen models are two feet deep and round, giving them more room for a small plunge setup, while the Rubbermaid is only 12 inches deep and has a drain plug that supports easier emptying. A larger tank can be more inviting, but it also takes more space, water, and care. I rank the options by their stated dimensions and construction, their practical suitability as a stock-tank-style pool, and the clarity of their tradeoffs—not by claims the product details do not support.

Key Takeaways
Most room to spread out: The Behlen Country 8-foot round tank has the largest stated footprint and a 2-foot depth, though buyers should plan for the extra space and water it requires.
Easiest listed emptying feature: Rubbermaid‘s BRUTE 50-gallon tank includes an oversized drain plug, but its 12-inch depth makes it a shallow cooling basin rather than a deep plunge pool.
Middle-size alternative: The Behlen 6-foot round tank keeps the same stated 2-foot depth as the 8-foot model with a smaller footprint, while still requiring substantial space compared with the Rubbermaid.
Material changes the decision: Behlen lists poly construction, while Rubbermaid specifies structural foam plastic and weather, impact, and corrosion resistance.
Verify pool setup before buying: The descriptions do not confirm filtration hookups, liner requirements, or pool-use approval for any of these tanks.

More Details on Our Top Picks
Behlen Country FarmFlex Round Stock Tank, 8 ft × 2 ft
The 8-foot round footprint makes this Behlen the strongest candidate in the group for buyers who want a stock tank that feels more like a shared plunge basin than a solo cooling tub. Its listed 2-foot depth also gives more immersion than the Rubbermaid BRUTE, which is only 12 inches deep. Compared with the 6-foot Behlen, this model offers more room to sit and move, but it also asks for a larger, level installation area and more water.
Behlen describes the tank as durable poly and suitable for livestock watering, bathing dogs, and wildlife use. That range supports the case for a robust utility container, but the listing does not spell out pool fittings, circulation compatibility, or a human-swimming warranty. I would treat it as the most promising conversion candidate here, not a ready-made pool. The round shape avoids corners and gives users a continuous basin, while its size can make setup, cleaning, and water replacement more involved than with the smaller options.
For a buyer choosing strictly among these three, this is my lead pick when space and capacity matter most. The 6-foot Behlen is the more restrained round alternative, and the Rubbermaid offers easier stated drainage but much less depth. Before committing, confirm the actual dimensions and any intended pool-conversion guidance, then account for a stable base and a plan for managing the water.
Pros:- 8-foot round dimensions provide the largest stated footprint in this comparison.
- 2-foot listed depth allows more immersion than the Rubbermaid’s 12-inch basin.
- Poly construction is described as durable for farm and ranch use.
- Versatile shape and use description also suits livestock, dog bathing, or pond applications.
Cons:- Large footprint demands more outdoor space and careful placement.
- The listing does not confirm pool plumbing, filtration compatibility, or swimming-use approval.
- A larger tank can take more water and effort to clean or change than the other options.
Best for: Buyers with a spacious, level outdoor area who want the largest round tank in this comparison for a plunge-style setup.
Not ideal for: Small patios, buyers seeking a ready-to-use swimming pool with confirmed filtration connections, or anyone who wants a compact basin that is easy to empty frequently.
- Brand:Behlen Country
- Dimensions:8 ft × 2 ft
- Shape:Round
- Material:Poly
- Manufacturer part number:5211308809
- UPC:017141001650

Our verdict“I recommend the 8-foot Behlen for buyers who want the most room and depth in this lineup and can handle the larger installation and maintenance needs.”
Behlen Country FarmFlex Round Stock Tank, 6 ft x 2 ft, Poly
If the 8-foot Behlen seems like more tank than your yard needs, this 6-foot round FarmFlex keeps the same stated two-foot depth in a smaller footprint. That makes it the more practical Behlen choice for a modest yard or a household that wants a plunge basin without giving it the space required by the larger model. Compared with the Rubbermaid, it is deeper and round, but it does not come with the Rubbermaid’s specifically described oversized drain plug.
The listing calls the poly design flexible and suitable for farm and ranch use, with other uses including dog bathing and wildlife habitat. It also mentions a variety of colors, which gives buyers a choice beyond the black Rubbermaid, though the supplied details do not identify which colors are available for this exact listing. Its dimensions are shown as 72 × 72 × 24 inches, which align with a 6-foot round tank and 2-foot height. The listed weight of 0.01 ounces is not credible for a tank of this size, so I would not use that figure for delivery planning; confirm actual shipping weight with the seller.
This model earns the middle position because it preserves the depth advantage of the 8-foot Behlen while trimming the footprint. It is not a small, low-maintenance tub, and the product details do not establish that it is built or warrantied as a swimming pool. I would choose it over the 8-foot version when yard space is the binding constraint, and over the Rubbermaid when greater depth matters more than a listed drain feature.
Pros:- Six-foot round dimensions take less space than the 8-foot Behlen.
- Listed 24-inch height provides more depth than the 12-inch Rubbermaid tank.
- Poly construction and flexible design suit general farm and ranch uses.
- The product description notes availability in a variety of colors.
Cons:- The listing does not specify a drain plug or pool-conversion fittings.
- The stated 0.01-ounce weight is implausible and should be verified before delivery planning.
- It still needs meaningful floor space and water management compared with a shallow utility tank.
Best for: Buyers who want a round, two-foot-deep stock tank but have less room than an 8-foot model requires.
Not ideal for: Anyone looking for a compact patio basin, a confirmed pool-ready tank, or reliable shipping-weight information from the supplied listing.
- Brand:Behlen Country
- Dimensions:72 × 72 × 24 in
- Shape:Round
- Material:Poly
- Model:52113068
- Weight listed:0.01 oz (verify with seller)
- Number of items:1 tank
Our verdict“I would choose this 6-foot Behlen when depth and a round basin matter, but the 8-foot model is better for maximum room and Rubbermaid is clearer on drainage.”
Rubbermaid Commercial Products BRUTE 50-Gallon Stock Tank
The Rubbermaid BRUTE is the clearest fit here for buyers who prioritize compact size and straightforward emptying over depth. Its 50-gallon capacity and 52 × 31 × 12-inch dimensions make it far smaller and shallower than either Behlen round tank. That limits it as a pool: at 12 inches deep, it is better framed as a cooling basin or shallow soak than as a plunge pool for full-body immersion.
Where it stands out is the construction detail. Rubbermaid specifies structural foam plastic designed to resist weather, impacts, and corrosion, with body stiffeners, a ribbed base, a smooth basin, and an oversized drain plug. These details speak to durability and easier emptying more clearly than the Behlen listings do. The 10-year limited warranty is also stated, although buyers should read its conditions and verify whether their intended use is covered. Smooth surfaces and no sharp edges are useful for animal care, but those claims do not substitute for confirmation of pool suitability.
Compared with the Behlen 6-foot tank, the Rubbermaid sacrifices depth and roundness while gaining a specific drain feature and a much smaller water volume. Against the 8-foot Behlen, it is far easier to place and likely simpler to empty, but it cannot offer similar room. I rank it third as a stock tank pool because its shallow profile works against swimming; I would still pick it first for a buyer who wants a compact outdoor water basin that can be drained and cleaned with less effort.
Pros:- 50-gallon capacity is substantially smaller than the Behlen tanks’ implied capacity from their dimensions.
- Oversized drain plug is specifically described for easier emptying and cleaning.
- Structural foam construction is stated to resist weather, impact, and corrosion.
- Includes a 10-year limited warranty, subject to its terms.
Cons:- At 12 inches deep, it offers less immersion than either Behlen model.
- Rectangular dimensions provide a different, less pool-like layout than the Behlen round tanks.
- The product details do not establish pool-use approval or filtration compatibility.
Best for: Buyers seeking a small, shallow outdoor cooling tub or utility basin with a stated oversized drain plug and detailed durability features.
Not ideal for: People wanting a two-foot-deep plunge pool, room for multiple adults, or a round tank with a larger bathing area.
- Capacity:50 gallons
- Dimensions:52 × 31 × 12 in
- Material:Structural foam plastic
- Color:Black
- Finish:Smooth
- Drain:Oversized drain plug
- Warranty:10-year limited warranty
- Country of manufacture:USA
- Model number:FG424300BLA
Our verdict“I recommend the Rubbermaid for a shallow, easy-to-drain cooling basin, while buyers wanting a genuine plunge-style depth should choose one of the Behlen tanks.”
How We Picked
I compared these three products against what a buyer searching for a stock tank pool needs to decide: usable footprint and depth, stated material and durability details, and how straightforward the tank appears to drain and maintain. I gave the most weight to the measurements because they determine whether the tank can serve as a plunge-style pool, fit the intended space, and hold a manageable amount of water. The 8-foot Behlen ranks first for buyers prioritizing room; the 6-foot Behlen follows as a smaller round alternative; and the Rubbermaid ranks third for pool use because its shallow 12-inch basin offers less immersion, despite the clearest drainage feature.
I also looked for details that could materially affect a pool conversion, including drain configuration, surface characteristics, and whether any product description explicitly identifies pool fittings or filtration support. The Rubbermaid description specifies an oversized drain plug and smooth basin; the Behlen listings emphasize multipurpose farm use. Since none of the supplied descriptions confirms pool-specific plumbing or human-use certification, I do not treat those features as present. I excluded price and customer feedback from the ranking and avoided assuming that animal-use durability automatically proves suitability for swimming. Buyers should verify intended use, placement, and any conversion needs with the manufacturer before purchase.

Factors to Consider When Choosing Best Stock Tank Pools
A stock tank can serve as a simple outdoor plunge basin, but the right choice depends on the specific space and upkeep you can support. I would settle the physical setup first, then check the tank’s intended use and maintenance requirements.Choose depth and footprint before material
For pool-style use, depth and interior room shape the experience more than color or minor construction details. The two Behlen tanks are listed at two feet deep, while the Rubbermaid is 12 inches high. That difference decides whether you can sit immersed or only cool off in shallow water. The 8-foot Behlen provides the largest footprint; the 6-foot version keeps the same stated depth with less floor space. The Rubbermaid is the compact pick, but its shallow basin makes it a different kind of water setup.
Measure the intended location, including clearance for getting in and out and access to the drain. Tanks filled with water are heavy, so consider the support surface and how water will flow away when emptied. These listings do not provide filled weights or installation instructions. Check with the manufacturer or a qualified installer if the tank will sit on a deck, elevated platform, or any surface with uncertain load capacity.
Match the material claims to your use
Both Behlen listings identify poly construction, and the larger model is described as durable and versatile for farm and ranch uses. The 6-foot version is also described as flexible. Rubbermaid identifies structural foam plastic and specifically lists weather, impact, and corrosion resistance. Those claims help compare the stated construction, but they do not make the tanks interchangeable or establish a pool rating. Ask whether repeated human use, prolonged water storage, cleaning agents, and outdoor exposure fit the manufacturer’s guidance.
The Rubbermaid description also specifies a smooth basin, ribbed base, and built-in body stiffeners. These details are relevant to day-to-day handling and structural support, though a ribbed base can affect how a basin feels underfoot. The Behlen product details give less construction detail. I would compare manufacturer documentation for cleaning, UV exposure, and safe water contact before choosing a tank for regular bathing.
Plan drainage, water care, and conversion needs
The Rubbermaid is the only option here whose description calls out an oversized drain plug. That makes emptying easier to evaluate, but buyers should still check where the outlet sits and whether a hose or other adapter is needed. The Behlen descriptions do not specify drain hardware. Confirm how each model drains before purchase, particularly if frequent water changes are part of the plan.
None of the provided product details confirms a filtration connection, pump compatibility, or pool sanitation instructions. A tank may hold water without being designed for maintained swimming water. If you plan regular use, check with the manufacturer about safe water care, any required liner or fittings, and whether modifications could affect warranty coverage. Avoid drilling or cutting until you have those answers.
Check placement and safe access
A larger tank needs a level, stable surface and room to approach it safely. The 8-foot Behlen is the most demanding choice for placement; the 6-foot model trims the footprint but still measures six feet across. The Rubbermaid fits more compact areas, though its rectangular form needs a different layout. Think about shade, privacy, nearby drainage, and whether children or pets can reach the water unsupervised.
Stock tanks are utility products in these listings, not specified swimming pools. Check the intended-use guidance and consider safe entry and exit, water temperature, supervision, and barriers appropriate to the household. Do not assume that a two-foot side wall is a safe ladder or step. A setup that is easy to fill can still require planning for access and water disposal.
Compare the three roles
I would start with the 8-foot Behlen if the main goal is a roomy round plunge and the site can accommodate it. Choose the 6-foot Behlen when you want comparable listed depth in a smaller round footprint. The Rubbermaid BRUTE makes more sense when compact size, a shallow basin, and a stated drain plug matter more than swimming depth. This is the clearest way to separate the options: room, mid-size depth, or compact drainage.
Before ordering, confirm exact dimensions, included drain components, shipping weight, warranty terms, and suitability for the intended use. The 6-foot listing’s stated weight is especially suspect for a tank this large, so ask the seller to verify it. That information can change delivery plans and help avoid surprises when the tank arrives.
Frequently Asked Questions
Which of these stock tanks is best for a plunge-style pool?
I would choose the 8-foot Behlen if I had the outdoor space and wanted the largest round footprint in this comparison. Its listed two-foot depth is more suitable for immersion than the Rubbermaid’s 12-inch basin, and it offers more room than the 6-foot Behlen. It remains a farm-use tank in the supplied description, so I would verify pool conversion guidance and maintenance requirements before relying on it as a regular swimming setup.
Is the Rubbermaid BRUTE 50-gallon tank deep enough to swim in?
Its listed height is 12 inches, so I would treat it as a shallow cooling tub or soaking basin rather than a swimming pool. It has a useful oversized drain plug and detailed durability features, but those advantages do not make up for the limited immersion if your goal is a plunge pool. Either Behlen model lists a two-foot depth and is the better fit for buyers prioritizing depth.
Which tank is better for a smaller yard?
The Rubbermaid has the smallest stated footprint at 52 × 31 inches, so it is the easiest of these three to fit into a tight outdoor area. Its shallow basin is a meaningful compromise. If you specifically want a round, deeper stock tank, the 6-foot Behlen is the more compact Behlen choice, but its 72-inch diameter still calls for substantially more room than the Rubbermaid.
Can I connect a pump or filter to these tanks?
The supplied descriptions do not confirm pump or filter connections for any of the three products. Rubbermaid lists an oversized drain plug, but that is not evidence of a filtration port. I would check the manufacturer’s specifications and warranty guidance before adding fittings or modifying a tank, since drilling or cutting may affect its structural integrity or coverage.
What should I check before using a stock tank as a pool?
I would confirm that the manufacturer supports the intended water-contact use, verify the tank’s dimensions and drainage method, and plan for a stable level base and safe entry and exit. Ask about cleaning, water treatment, UV exposure, and whether a liner or conversion fittings are required. The supplied listings describe utility tanks and do not establish human-swimming certification or pool sanitation guidance, so those details need direct confirmation.
Conclusion
For buyers who want the roomiest round plunge and have a suitable outdoor area, I recommend the Behlen Country 8-foot FarmFlex. If you want a similar listed depth in a more restrained footprint, the 6-foot Behlen is the sensible middle choice. For a shallow cooling basin where compact dimensions and easier stated drainage matter most, choose the Rubbermaid BRUTE. In every case, verify pool-use suitability, maintenance guidance, and any conversion needs before filling the tank for regular swimming.
