Top 5 Backyard Water Slides for Adults

When I was a kid, the standard for a great backyard was the waterslide. Now that you’re an adult, that opinion hasn’t changed. If you want the best backyard water slides for adults, review dimensions, materials, and weight limits to make sure they fit your space and fit the adults who use them. You should also consider fitment, inflation, and if you wish to include additional accessories such as body panels.

What to Consider When Shopping for Adult Size Backyard Water Slides

Water slides are available in different sizes. Just be sure to check your slide dimensions and available space before purchasing. Also, keep an eye on the slide’s weight restrictions. Some of the water slides are made just for kids, while others are suitable for kids and adults, so I’ve included the options below that can hold 180 pounds or more. When it comes to water slide materials, look for PVC, nylon, or other heavy-duty plastics for durability and puncture resistance, as well as reinforced stitching for added protection.

Types of Backyard Water Slides

Water slides come in a variety of styles. You can get an inflatable water slide, which may include water sprinklers, climbing walls, basketball hoops, and lounging pools to turn your backyard into a mini water park. This option will usually be more expensive and require more time to set up and remove. However, most of these types of slides will include an inflatable pump to make it a little easier. Other water slides are ground-mounted and can have sprinklers, crash pads at the end of the slide, side fenders or body panels for a smoother slide. These types of slides are more budget friendly but may require a pump to inflate the fenders and some setup to make sure they are safe on the ground and there are no sticks or rocks in the way. And if you have access to a pool or pier, you may want to have a water slide attached to the side so you can slide directly into the water.

Whether your space is large or small, these are the best adult backyard water slides on Amazon.

1. 1 inflatable water slide with relaxation pool


  • Carrying bag, air pump, and four stakes included
  • Water sprinklers built into the top and bottom of the slide
  • Swimming pool
  • Made of heavy-duty nylon


  • It must be completely dry before deflation

This inflatable water slide has the power to transform your backyard. It has a climbing wall to climb to the top of the slide and a relaxation pool at the bottom. You’ll need to connect it to a hose for the built-in atomizers to work, getting the slide wet and filling the pool. Inflation is quick with the included pump, and the slide is made of durable, puncture-resistant, heavy-duty nylon with reinforced stitching and a 350-pound weight limit. One reviewer raves: “It’s up to a lot of kids now and even a couple of adults! Worth it. Very sturdy. Easy to set up and take down.”

Helpful Amazon review: “It folds up easily and its storage bag is quite large. It blew up within 2 minutes. The water for the sprinklers hardly needs to have a good flow, so that’s OK. Adults can ‘play’ too!!! Highly recommended!”

Dimensions: 12.4 x 17 x 7.8 feet | The pump includes: yes | Weight Limit: 350 pounds

2. Long and wide water slide


  • big size
  • Fasteners included


  • You need to provide the tape that holds the fasteners on the slide
  • You also need to provide body panels and spray jets if desired
  • Non-Adjustable

If you are looking for a no-frills water slide that covers your entire backyard, then this is the slide for you. It’s made of thick, specially-designed plastic with a UV-protected surface and stretches 50 feet long and 10 feet wide, with locking holes along the sides where you can install it on the floor. Fasteners and wedges for setup are included, but reviewers report that the tape that holds the fasteners to the slide is not, so you may want to have some masking tape on hand. There are no spray jets, but you can add your own sprinkler or keep the hose at the top of the slide and spray occasionally. You can also provide your own inflatable body panels. The slide is also rated to hold 256 pounds per square foot, and has a total area of ​​500 square feet.

Helpful Amazon review: “I got this for my daughters graduation party and both kids and adults were amazed!! The next day we all felt the pain. It’s huge!! So make sure you have a big enough space for it. Run the sprinklers or hose and add some soap and it’s ready to use!”

Dimensions: 50 x 10 feet | The pump includes: not available | Weight Limit: no one

3. Budget water slide with two body panels


  • Includes two body panels (each 26″ x 17″)
  • Includes repair kit, mounting screws, and hose adapter
  • Sprinklers run along the slide


  • The pump is not included
  • The hose adapter may not fit properly

This budget-friendly water slide features two aisles with inflatable bumpers to keep the water and people on the slide, plus sprinklers on the sides and center and a crash basin at the end. It comes with two inflatable body panels that can help make a smoother slide, with a maximum weight of 180lbs. Made of heavy-duty PVC, the slide is durable and has no weight limit but includes a repair kit just in case. It also includes anchor bolts to secure it to the ground and an adapter to keep the hose connected and the water pumped in. However, reviewers report that the adapter does not fit all hoses, and you’ll have to supply your own pump to inflate the fenders.

Helpful Amazon review: “Fun for kids and adults. Kids aged 8, 14 and 39 use it. No major issues, although it wasn’t easy to inflate without a pump.” […] It wasn’t fully connected to our hose correctly, water was flowing into the connector even though it was completely twisted, but it didn’t affect use. The water is still rising high from the water holes. I imagine this will continue all summer or longer. Lots of fun and looks solid.”

Dimensions: 20 x 6 feet | The pump includes: no | Weight Limit: None for the slide, 180 lbs for the body panels

4. Triple inflatable water slide


  • Includes 3 water slides, spray heads, water mist, climbing wall, basketball hoop and relaxation pool
  • Includes pump, stakes and carrying case


  • expensive
  • Difficult to empty and dry

Turn your backyard into its own water park with this deluxe inflatable water slide. All you have to do is attach a hose, and the sprinkler heads will wet the three water slides as you fill the lay-down tub. The climbing wall makes it convenient to climb the slide, and the water nozzle at the bottom provides some extra water sprays. If you would like to add a toy item, there is a basketball hoop, but the balls are sold separately. The entire assembly is made of puncture-resistant, heavy-duty nylon with reinforced stitching, and has a maximum weight of 468 pounds. The pump, pegs, and carrying case are included, so setup and storage are easy and convenient. Reviewers say the downside is emptying, drying and removing everything when not in use.

Helpful Amazon review: “The perfect water slide for kids and adults in your own backyard. It was very easy to make the pool area bigger than expected!! ”

5. Pond or basin water slide


  • It can be attached to the side of the pool or the sidewalk
  • Comes in multiple designs


  • Pump and mounting ropes not included

If your backyard includes a pool or pier, adding an inflatable water slide can make it even more fun. There are plastic handles near the inflatable side rails to help you climb over the slide, and at 6 feet wide, there’s potential room for adults to descend at the same time. This slide is made of heavy-duty PVC and has loops that allow it to attach to an inflatable walkway or dock posts. Unfortunately, mounting ropes are not included, and you will have to use your own pump. Reviewers report that any electric pump will work, like the kind you use for an air mattress or to blow up balloons, and recommend placing the bottom of the slide 12 to 18 inches above the edge of the pool for a smooth descent into the water.

Helpful Amazon review: “The slide has foot rests and handles that make it easy to climb. Bonus is that the 200 lb adults were also able to climb and use as well. Overall a sturdy float/slide. I recommend.”

Dimensions: 9 x 7 x 4 feet | The pump includes: no | Weight Limit: 400 pounds depending on the brand’s website
