More Detailed Inflatable Water Slide Reviews

BeBoP Spin Combo Large Bouncy Castle and Water Slide

This BeBop combination bouncy castle and waterslide is tons of fun for kids aged 3-10. It wins top spot for the best kids inflatable water slide for the UK market!

This enormous kids inflatable water slide turns your garden into a theme park. It’s the largest of my recommendations – the kids are seriously going to love this giant-sized inflatable.

It measures 400cms by 350cms by 240cms, which is more than enough room for four kids to enjoy bouncing, splashing and laughing to their heart’s content.

You simply inflate and connect it to a hosepipe for a full-on water slide. Then, when summer is over use it as a bouncy castle without the water – a 2 in 1 outdoor toy what more could you ask for?

There are plenty of features such as the water cannon, climbing wall, a sprayer that sprinkles water across the canopy, a large-sized splash pool (measuring 170cms by 200cms), a bouncy slide and a target. Phew!

Be-bop is a great make, so safety anchor pegs are included. It’s important to keep inflatables pegged to the ground so they don’t blow over in high winds. Make sure yours isn’t going to budge no matter how boisterous the fun gets.

This kids inflatable water slide has a blower included in the price which is essential because it takes a lot of air to get this one up. Reviews suggest the blower inflates the waterslide within a few minutes.

The Spin Combo is made from tough PVC and nylon so it’ll take a lot to puncture the high-quality materials, but there’s a repair kit just in case someone jumps aboard in shoes.

There are very small pinpricks in the material to relieve pressure points and ensure the waterslide doesn’t explode at full capacity – this is a sign of good quality – as is the storage bag.

This is a large waterslide and a best seller with excellent reviews. For the money it’s the best inflatable water slide for the UK market!

BeBoP Total Wipeout Inflatable Water Slide Combo 

This Bebop Total Wipeout Waterslide combo is made for fun with friends and competitive siblings.

This is another large combination bouncy castle and waterslide by Bebop but this one has queue-beating twin water lanes that allow several kids to race at the same time.

The extras are impressive too. It has the essential water cannon, a canopy water spray, splash pool, and a climbing wall to keep them entertained.

It’s a touch smaller than the Spin Combo above at 330cms by 245cms but it can still take up to four children aged 3- 10.

High quality lightweight laminated PVC and nylon keeps the bounce and protects against tears, although if the worst happens there’s a repair kit included. The Total Wipeout castle also comes equipped with an inflatable castle blower fan – a must for inflatables of this size.

As far as safety goes it’s made from good quality materials and has the all-important anchor pegs. Peg the castle down hard and check it regularly as all the bouncing and excitement can work them loose.

When it’s not sunny you can inflate the castle and use it as a bouncy castle instead – a great way to relieve boredom during the holidays and get them away from the PlayStation.

This kids inflatable water slide is an interesting and sturdy slide that will keep all the kids entertained!

BeBoP Neptune Towers Inflatable Water Slide Bouncy Castle

This BeBoP Neptune Towers Inflatable Water Slide Bouncy Castle is such a great waterslide bouncy castle combination! Another one of the best inflatable water slides available for the UK market.

This kids inflatable water slide set-up has a fantastic twin waterslide and water cannon that aims at the sliders. This is really well thought-out because it means three kids are engaged with one another rather than arguing over whose turn it is. A canon pointing at the water slide also means you and the cat won’t be in for any unwanted wet surprises.

Alongside those twin lanes and water canon, there’s an easy climb wall and a large splash pool.

It’s a pretty hefty size at 420cms by 300cms by 230cms and looks impressive when set up.

Good quality inflatables include a blower fan and this has one that’s more powerful than most at 450 watts for super-quick inflating time.

Safety features are important so it’s good to know this is made from high-quality laminated PVC and nylon. It’s unlikely but if you’re unfortunate enough to get a puncture use the enclosed repair kit (or a bicycle inner tube repair kit if you get more than one puncture).

As with my other recommendations you can use this on summer days as a water park and a straight-forward bouncy castle to brighten dull days. They are really useful pieces of kit.

This kids inflatable water slide is an unusual, fun design with plenty of entertainment power!

BeBoP Pirate Boat Inflatable Bouncy Water Slide for Kids

This BeBoP Pirate Boat Inflatable Bouncy Water Slide is the best kids inflatable water slide for the young and young at heart.

Bebop has great ideas for waterslides, and they haven’t left out wannabe pirates.

This inflatable waterslide measures 457cms by 292cm 284cms and will take three pirates aged 3-10.

It’s ship-shaped in bright attractive colours with a water cannon pointed at the sliders. Good thinking Bebop, parents keep dry and the water runs down the slide into the splash pool so there’s less wastage.

It’s a cinch to set up too – simply attach your hosepipe to the water tubing and you’re off on the high seas me-hearties.

Extras include the pirate flag (of course!) a netted canopy for safety and an easy-climb wall with foot holes and handles for the little pirates.

Back to the practicalities – the package includes a blower-fan, which stays on continually during use, and anchor pegs to keep everyone safe. I keep saying it but make sure these are used properly.

The all-important patch repair kit is included in case you spring a leak, and there’s a smart carry bag too.

This is a great pirate themed large inflatable water slide that kids of all ages will love – and isn’t that what waterslides are all about?

Costway Moonwalk Bouncy Castle and Water Slide

The Costway Moonwalk Bouncy Castle and Water Slide is great value and inflates in under two minutes.

Younger kids are going to love the Moonwalk bouncy castle and waterslide that measures a hefty 356cms x 255cms by 244cms.

It’s bright and fun with everything you’d expect from a water park. There’s a good length slide, an easy climb wall, a water cannon, and a netted canopy.

The water collection area doubles as a large splash pad which is a good size for the very little ones. You’re able to sit in the water with a toddler while an older child goes wild on the slide without any head-crunching incidents.

The Moonwalk kids inflatable water slide is made from heavy duty nylon oxford fabric and has a puncture repair kit just in case.

Of course it has anchor pegs too, I wouldn’t recommend an inflatable without those, but there aren’t many so you might want to supplement them with some tent pegs to stay on the safe side.

It doesn’t have a blower fan, but something has to give at the cheaper price. You’ll need to buy this separately, its big so don’t think you can make-do with a hand-pump or you’ll be in the garden for 48 hours.

Overall this kids water slide is great value and doubles as a bouncy castle on grey days.

Inflatable Water Slide Buying Guide

Buying an inflatable water slide for the UK market isn’t an easy decision, so take a look at my buyer’s guide before you commit the cash because you might come across something that hadn’t occurred to you. Just imagine the disaster zone if your waterslide arrives and something is wrong!


The bigger the better right? Not necessarily. The size of your waterslide is dictated by the size of your garden and that means the flat area of your garden.

To make sure it’ll fit safely measure out the required space with a piece of string or skipping ropes, leaving some room around the edges that’s fine getting wet. Kids are capable of projectile splashing water for many miles.

It goes without saying but ensure you have enough space to keep it well away from flower borders, pet enclosures and fence lines. The neighbours won’t be happy if they have unwanted peepers looking into their garden all day.


It’s great when all the kids can get into the waterslide at once, but hold on.

Too many kids and the waterslide will either burst a seam or tip over. The manufacturer’s instructions will recommend a maximum capacity and if it says three kids aged 3-10 then stick to it – or you may watch your investment deflate before your eyes.

Once everyone knows you have a waterslide they’ll all be angling for an invite, but don’t invite four kids if the waterslide will only hold three. Imagine the fallout – a horrible argument that makes it a waste of effort and money.

You’re better off spending more on a bigger size waterslide so everyone gets a turn.


The better inflatables are manufactured with strong PVC material that’s difficult to puncture. Inflatables take a lot of punishment because when they’re excited kids don’t hold back.

Look for good quality PVC material or a heavy gauge vinyl. Commercial strength nylon is a tough material for waterslides too.

The tubing that connects the waterslide to your garden hose should be good and thick, and the connectors of top-notch quality. It isn’t a waterslide without water and connections that keeping falling apart ruins everyone’s fun.

Any material no matter how tough will perish if you leave it outside for months on end. Sunlight damages PVC so if the kids are done playing with it, allow the material to dry naturally before packing it away somewhere dark and cool.


Think about how often you’ll use the waterslide and be honest.

If it’s so much of a faff that it’s left packed away or makes an annual appearance at the birthday party then you’re better off saving your money for days out.

However, if you have kids that are packed with energy, or you’re an outdoor kind of family, getting the inflatable out on a regular basis is a great idea.

Parents with constraints in the holidays, such as work at home days or grandparent babysitters, might find a waterslide gives you peace and time to accomplish tasks without the dreaded electronic babysitter taking over.


Pay particular attention to age or weight limits on the manufacturer’s instructions.

Waterslides are great fun for all ages, but too much weight makes them dangerous, toppling over or violently bursting a seam.

Most inflatables will accommodate 3-10-year-olds, but bear in mind that a ten-year-old weighs much more than a three-year-old! If you have three 10-year-olds on the inflatable it’s pushing the boundaries and there might be an accident.


Ah, the age-old problem of storage!

Many good quality inflatable water slides are sold with their own carry cases but it’s almost impossible to fit them in once used unless you have the patience of a saint and are happy to sit there folding the creases to remove every atom of air.

If like me you tend to lose interest after 4 minutes you’re going to need a bigger box or a shed to store it in.

Make sure the waterslide is completely dry before packing it away or it’ll grow mould and become unusable. Keep it stored away from extreme temperatures and bright lights too because they thin the materials making it more likely you’ll experience a deflation next time around.


How To Inflate a Waterslide?

Most of the better quality waterslides are sold with a blower to make light work of inflation.  If yours doesn’t include a blower you’ll need to get one – blowing it up with your bike pump or lungs will take all eternity!

Are they safe?

If it’s made according to accreditation and used as the instructions indicate waterslides are safe. That goes for all outdoor equipment.

There is the extra issue of water and small children to contend with, so make sure they behave sensibly and never leave them unsupervised.

What About Punctures?

With good quality inflatables punctures are rare, but they can happen. That’s why the top makes include a decent puncture repair kit.

There are three main ways to avoid punctures:

  • Never wear shoes, remove watches and jewellery including hair slides, and avoid playing with hard toys. Don’t let your dog join in either – sharp claws and PVC do not mix.
  • When you set up the waterslide check thoroughly beneath it for stones or pieces of wood – anything that could rip the material. Try putting children’s foam carpet tiles down first it.
  • Don’t drag it along when deflated as this increases the likelihood of a puncture.

Will It Make my Grass Muddy?

Inflatable waterslides attach to a hose pipe. The water is not recycled but collected in the splash pool. Any overflow will therefore will soak into your grass.

This is good news during droughts or hot days, but repeat sessions may make the area muddy. Think about moving the waterslide around or setting a time limit on how long the hose can run for.

To Buy Or Not To Buy?

Inflatable water slides are tons of fun for kids because they universally love playing in the water.

From adventurers that throw themselves down the slide to quieter kids who like to float and splash in the pool section – it’s all fun.

You might consider spending a few hundred pounds on an inflatable water castle a bit rich but think about the money you’ll spend taking your kids out over the summer.

It’ll cost at least £100 a day, if not more. A waterslide is pretty good value in comparison if it’s used time and time again.

And let’s not forget the peace they can bring a harassed parent – that’s priceless.
