A pickup truck and a hot afternoon are a natural pairing, and turning the bed into a quick-fill wading spot has become a backyard hack for tailgates, camping trips, and driveway play. The hard part is choosing the right base liner, the right tarp, and the right support gear so the setup holds water, survives the sun, and packs down without a fight. This roundup walks through six options that work well together or on their own, depending on how mobile you want your splash zone to be.
The Lineup, Simplified
Xpose Safety 5′ x 7′ Ultra Heavy Duty Tarp 20 Mil
RAINDEWAY 4×30 Feet Heavy Duty Striped Tarp 12 Mil
PAX 50Pcs 55x55mm Square Tire Repair Patches
Gard Summer Waves Inflatable Truck Bed Pool 66″x62″x21″
HIKULA Inflatable Round Floating Ring Water Hammock
RAINDEWAY 6 Feet Round Tarp Waterproof Circle
The Strengths Of Each Pick
If you want a liner that survives season after season in the sun, the Xpose Safety tarp earns its spot at the top of the list. At 20 mil thick, it sits well above the typical 12-to-16 mil range you find on most hardware-store tarps, and the reversible white-and-brown finish helps reflect heat during long afternoons. The 5-by-7-foot footprint is a natural match for shorter truck beds or for split-bed use when you only want to line a portion of the cargo area.
Compared to the RAINDEWAY striped tarp covered below, this one leans toward rigidity over flexibility, so folding and creasing become part of storage. For a family that sets up in the same driveway most weekends, the extra weight is a fair trade for puncture resistance. Travelers chasing the lightest possible pack should look at the round RAINDEWAY option instead.
Real-World Strengths
- 20 mil thickness resists punctures from tailgate hardware, toys, and dog claws far better than economy tarps.
- Reinforced corners and all-weather construction handle repeated wet-and-dry cycles without edge fraying.
- Reversible color lets you choose a cooler white surface for hot days or a brown side for visual blending on camp trips.
- UV treatment helps the material hold up through full-sun seasons, which matters when the pool stays inflated for hours.
Points To Note
- The stiffness that makes it tough also makes it harder to fold flat for small storage bins.
- 5-by-7 may fall short of full-size short-bed or long-bed dimensions, so measure the bed before committing.
- Heavier than lighter 12 mil alternatives, which can wear on tailgate hinges during repeated setup.
Right Fit For
You want a thick, durable liner for repeated driveway or campsite setups and do not mind a bit of extra weight in exchange for puncture resistance.
Look Elsewhere When
You need a full-length liner for a long bed and want something more flexible, in which case the RAINDEWAY 4×30 Feet Heavy Duty Striped Tarp 12 Mil is a smarter match.
Long-bed owners get a lot of tarp for a small spend with the RAINDEWAY striped option. The 4-by-30-foot sheet gives you room to drape over a full-size cargo bed and still have material left to wrap or fold up for ground coverage around the truck. At 12 mil with a 14×14 weave count, the polyethylene body feels closer to a contractor’s tarp than a bargain-bin cover, and the red-and-white stripes make it easy to spot at a crowded campsite.
The trade-off shows up in thickness: it does not match the Xpose Safety 20 mil tarp reviewed above, so sharp cargo hooks or repeated folding can wear the surface faster. For one-season use, or for anyone who wants to test a truck-bed pool setup before committing to a heavier liner, this striped tarp is a low-risk starting point. Owners who want a permanent setup should size up to a thicker option.
Advantages To Know
- Generous 4-by-30 dimensions cover most short and long truck beds with material to spare.
- Metal grommets spaced roughly every 23 inches let you tie it down or hang it as a sun shade.
- UV additives in the polyethylene slow fade and brittleness across sunny weekends.
- Light enough to fold and store in a milk crate behind the seat.
Trade-Offs To Consider
- 12 mil thickness is lighter than the Xpose Safety tarp and can scuff under heavy toys or pet paws.
- Striped polyethylene can feel slippery when wet, so secure the edges before kids climb in.
Best Suited To
You want a full-length liner on a smaller budget and plan to rotate the tarp between truck bed and ground cover duties.
Reach For A Different Pick When
You mainly want a compact round footprint for a kid’s wading zone, where the RAINDEWAY 6 Feet Round Tarp Waterproof Circle is a tidier match.
No truck-bed pool setup is fun with a flat tire, and the PAX patch kit earns its place in the cab as a roadside backup. The 55-by-55-millimeter square patches cover the common puncture sizes from nails, screws, and thorns, and the 50-piece count means you can make several repairs across a season before restocking. The patches work on radial and bias tires, which covers most pickup, trailer, and ATV setups you might tow to a campsite.
Versus the floating ring reviewed below, this kit is purely a maintenance tool, not part of the splash zone itself, so it lives in the glovebox rather than the bed. Anyone who hauls a pool, a boat, or a camper should keep one of these stashed, since a slow leak can end a weekend fast. Pair it with a plug-style repair for the cleanest fix on highway-grade punctures.
Bright Spots
- Fifty patches per can cover years of small punctures for the price of a single shop visit.
- Square shape gives slightly more surface area than round patches of the same dimension, which helps on sidewall nicks.
- Works on inner tubes, so the same tin covers bicycles, inflatables, and pool floats.
Small Caveats
- Adhesive and scuffer are not always bundled, so confirm the kit contents before counting on a full repair job at the trailhead.
- 55x55mm can run small for large gashes that need a boot-style patch.
Who Will Love This
You travel to remote camp spots and want a low-cost, long-lasting safety net for tire slow leaks.
Swap It Out When
You mainly need a float for the water itself rather than repair gear, in which case the HIKULA Inflatable Round Floating Ring Water Hammock fits the bill.
This is the only product in the roundup that was actually built for the job. The Summer Waves pool drops into a standard truck bed, inflates through two air chambers, and fills from a hose in minutes. At 66 by 62 by 21 inches, the basin fits a couple of kids or one adult lounger with room to spare, and the inflatable design means it stores flat in a closet during the off-season. No DIY framing, no custom tarp cuts, no measuring.
The honest read is that you trade a little durability for convenience. Compared to a tarp-and-liner setup built on the Xpose Safety 20 mil tarp covered earlier, this pool uses thinner material that can scuff against bed rails. For families who want a true plug-and-play experience and will treat the pool as a seasonal item, that trade is well worth it. Frequent travelers who want one piece of gear for both truck and ground might prefer the HIKULA floating ring instead.
The Practical Payoff
- Purpose-built shape saves the hours of measuring, cutting, and taping that a tarp liner requires.
- Two-chamber inflation lets you deflate fast for travel without waiting on a full air purge.
- Fits any standard pickup, so you do not need to match the pool to a specific bed length.
- Lightweight build packs into a duffel and weighs far less than a stacked tarp-and-frame setup.
Honest Caveats
- 21-inch depth is on the shallow side, so older kids and adults will sit rather than swim.
- Thin-walled PVC tends to scuff against metal bed rails, so adding a soft blanket underneath helps longevity.
Made For
Parents and casual hosts who want a fast, repeatable setup on weekends without a custom build.
A Better Fit Elsewhere
You need a pool that can move from the truck to a lake or beach without refilling, in which case the HIKULA Inflatable Round Floating Ring Water Hammock is the more flexible pick.
The HIKULA floating ring expands the truck-bed pool idea past the driveway and into the lake. The 8-foot or 10-foot round platform doubles as a water hammock, a dock, or a sunbathing mat, and the integrated ladder and cup holder push it past the basic pool-ring category. When you arrive at a campsite with a lake, you can pull the same float out of the truck bed and drop it into open water in minutes.
Compared to the Gard Summer Waves pool, this one trades contained wading for open-water lounging, so it suits a different kind of afternoon. You may find the bungee-style mesh needs a quick knot adjustment before the first use, since the factory setting is intentionally loose. Heavy-duty PVC construction helps the ring handle repeated inflation cycles across a full summer.
What Works In Its Favor
- Two available diameters (8FT and 10FT) let you size the float to your crew and storage space.
- Built-in ladder simplifies climbing out of the water without a separate accessory.
- Cup holder adds a small but useful touch for adults who want a drink within reach.
- Multi-zone layout supports sitting, lying flat, or partially submerged lounging.
Points To Keep In Mind
- Bungee knots can arrive loose, so plan a quick adjustment before the first swim.
- 10-foot size takes up significant truck bed space when deflated and stored.
Who Should Grab It
You split time between truck-bed wading and lake trips and want one float that handles both without swapping gear.
Not Your Match When
You want a contained, fill-and-soak pool that lives entirely in the truck bed, in which case the Gard Summer Waves Inflatable Truck Bed Pool is the more focused option.
Short beds and compact cargo areas call for a round footprint rather than a long rectangle, and the RAINDEWAY 6-foot circle fills that niche. The circular shape drapes evenly over a smaller pool ring or a kid-sized wading basin, eliminating the awkward folds you get when you cut down a rectangular tarp. Woven polyethylene with a 10×10 weave count gives the surface a solid, plastic-canvas feel, and reinforced edges with nylon rope trim help the perimeter resist tear-out under tension.
The trade-off shows up at the corners, which do not exist on a round tarp, so you lose the diagonal tie-down geometry that rectangular tarps provide. For ground cover, splash-pad lining, or a small wading pool, that limitation rarely matters. If you want a larger circle, RAINDEWAY also offers an 8-foot variant in the same product family.
Useful Touches
- Circular shape eliminates corner folds for cleaner drape over round pools and basins.
- Reinforced perimeter with nylon rope adds tear resistance where the tarp meets grommets or stakes.
- Available in 6-foot and 8-foot diameters for small and medium wading setups.
Practical Considerations
- Limited tie-down points compared to a rectangular tarp, so anchoring in wind takes more creativity.
- Smaller diameters may not reach across a full-size truck bed without overlap.
Perfect Match For
You want a tidy round liner for a kid’s wading pool or a small splash pad rather than a full bed fill.
Consider Something Else When
You need a full-coverage liner for a long cargo bed, where the RAINDEWAY 4×30 Feet Heavy Duty Striped Tarp 12 Mil is the better fit.
What Matters Most Before Choosing Truck Bed Swimming Pools
Bed Size and Pool Footprint
Standard short beds run about 5.5 to 6.5 feet, while long beds stretch past 8 feet, and matching the pool or liner to that footprint keeps water from sloshing over the sides. Inflatable pools like the Summer Waves pool land in the middle of the size range, while rectangular tarps give you room to cut and fold. Measure the inside of the bed at the wheel wells before committing to a shape.
Material Thickness and UV Resistance
Mil rating (the thickness of the plastic or fabric in thousandths of an inch) directly affects how long a liner survives in the sun, and a thicker 20 mil tarp outlasts a 12 mil option in full-sun setups. UV-resistant coatings slow the brittleness that turns exposed plastic into a cracking hazard by the second season. Storage out of direct sunlight when the pool is empty extends the life of every option in this list.
Portability and Storage
A truck-bed pool is only as useful as it is easy to break down. Inflatable pools and round tarps pack into a closet, while long rectangular tarps usually need a garage wall or a cargo bag. The HIKULA floating ring takes up the most space when deflated, so plan storage around the larger 10-foot option before buying.
Safety and Anchoring
A water-filled bed shifts weight toward the rear axle, so a secured tarp and a parked truck on level ground are the baseline. Grommet spacing on the rectangular tarps makes tie-downs easy, while the round tarp needs a few creative anchor points. Always drain the pool before driving, since sloshing water affects braking and handling.
Key Considerations Across These Picks
Where Shoppers Go Wrong
The most common slip-up is buying a tarp or pool based on nominal size without checking the actual finished dimensions, which can run a few inches short of the headline number. You may also find that a thin 6 mil tarp looks fine on day one and then leaks by week two once the folds crease. Measure the bed twice, pick a tarp with at least 12 mil thickness for seasonal use, and add a soft blanket under inflatable pools to cut scuffing against metal bed rails.
When Paying More Pays Off
Spending up on a 20 mil tarp or a purpose-built inflatable pool buys thicker material, tighter weave counts, and reinforced edges that hold up across multiple seasons. The upgrade makes sense for households that will set up the pool every weekend, while casual users who only need a few afternoons of splash time get enough life from a 12 mil option. Consider the upgrade worth it when storage, safety, and time saved on setup matter more than the lowest entry cost.
Frequently Asked Questions
Can any truck bed hold a full pool of water?
Most half-ton pickups handle a few hundred liters of water without strain, but long beds and heavier trucks give you the most flexibility. Always park on level ground and check the payload rating in the door jamb before filling.
How do you keep a truck-bed pool from leaking?
Lay a soft blanket or foam pad under the liner, smooth out every fold before filling, and avoid sharp edges on the tailgate. Inflatable pools benefit from a layer between the PVC and the metal bed rails to prevent scuffs that become pinholes.
Is a tarp liner better than an inflatable pool?
Tarps let you customize the size and shape, which helps with non-standard beds. Inflatable pools save setup time and look more polished, and they are easier for first-timers who do not want to measure, cut, or tape a custom liner.
How long does a typical truck-bed pool last?
A 20 mil tarp liner can last several full seasons, while a 12 mil tarp often shows wear after one. Purpose-built inflatable pools usually survive two to three summers with reasonable care, especially when stored dry and out of direct sunlight between uses.
Can you drive with water in the truck bed?
It is not recommended. Sloshing water affects vehicle balance, braking, and tire wear, and most local regulations treat an open water container in a moving bed as a safety hazard. Drain the pool fully before driving.
