Both inflatable and fixed pools are very popular now, but you have to be careful where you put them.

Most people don't realize that the bottom under their pool is just as important as the bottom of your expensive pool itself. Even grass can be disastrous.

Pool tiles are a great solution to this problem because they are light enough to lay on any surface, including sand! That means you can place your inflatable pool anywhere without worrying about leaks or ruining your subfloor.

I decided to test the most popular underlays and with this complete guide I'll show you which one to buy for your pool.

Swimming pool tiles as subfloor

The best I have found for an outdoor inflatable pool in your yard, for example if you want to put it on grass or on tiles are this one from DirectSupply. The tiles are infinitely expandable and nice and thick and comfortable, also for your feet as a soft surface, mold-resistant and you will be able to use them for years.

A very good rating on bol.com, nice and sturdy and even thick enough to use for your washing machine so that it no longer vibrates or shifts.

But there are many more models that may be more useful in different situations. You will find them in the table below, divided into the main categories:

What thickness of pool tiles should you buy?

This depends a bit on which surface you are going to set up the pool on. If you want to put it on the stones in the backyard, thicker pool tiles are wise.

If the pool is set up on the grass, you can do fine with thinner tiles, or even without tiles. Then consider a groundsheet.

Why buy swimming pool tiles?

If you have a pool, it is always recommended to buy tiles for underneath, although it is not required.

But why exactly?

We will give you three good reasons to use pool tiles in your pool.

It feels more pleasant than garden tiles

You can buy different types of pool tiles. You can go for soft tiles, but you can also opt for underlay tiles that mimic grass.

In any case, it is better to to choose subtiles instead of garden tiles.

Imagine that there are sharp edges on the garden tiles; then it can be a painful experience!

With under tiles you do not have the problem of sharp edges.

Optimal protection

Of course you want to have 100% fun with your swimming pool, and that includes getting in and out of the pool without any problems.

If you buy a swimming pool from a certain brand, you can order the under tiles of the same brand. For example, if you have bought a Bestway swimming pool, you can also order pool tiles from the same brand.

Of course you can also buy them from another brand, because swimming pool tiles are universal and can be used for any swimming pool.

With pool tiles, your pool is perfectly protected against damage.

The pool will also not be punctured by sharp particles from the ground.

Get in and out of the pool safely

Pool tiles usually don't get slippery and are much more flexible than garden tiles. This way you prevent nasty accidents.

Pool tiles are especially ideal for children when they run enthusiastically over the mat to jump into the pool. Should they accidentally fall or slip, the fall will be well absorbed thanks to the pool tiles.

Falls thus become much less painful and the children will be less likely to sustain wounds.

Always make sure that children swim safely! Here we have listed the best swimming armbands for you.

Frequently asked questions about pool tiles

How do you lay tiles under a swimming pool?

It's as easy as it looks!

It is simply a matter of connecting the puzzle pieces together.

Take the size of the pool into account, so that the pool will of course fit on the subfloor you have just installed.

Check in advance how many tiles you need and how many sets you have to buy. It is nice if you also put the tiles around the pool.

We have examined various swimming pool tiles and picked the best ones.

How do you choose the surface?

Before you start laying the tiles and the pool, you determine the surface.

This is an indispensable step in the process. Regardless of the size of your pool, determining the substrate is the first successful step in setting up or assembling the pool.

If you choose the wrong surface, it can cause damage.

There are a number of things to consider when choosing the substrate:

If you have taken all these points into account, you choose the right surface and then look for the right pool tiles.

Alternatives to pool tiles

There are various types of underlays for swimming pools.

Some people opt for a groundsheet, others for an underlay. You can also opt for artificial grass and foam tiles.

The type of subfloor must be selected based on the subfloor: grass, earth, gravel, sand, or pavement.

In general, the best solutions are rubber play tiles or a wooden deck. It not only looks good, these materials are also very suitable for placing a swimming pool.

With a wooden deck your pool will stand straight. You will also never suffer from sand or other dirt.

Can a swimming pool stand on grass?

Yes, you can put your pool on real grass. However, this cannot be longer than a few days.

If you do leave the pool on the grass for more than a few days, chances are that the grass under the pool will not survive.

You could possibly restore this again, but you will almost always keep seeing where the pool was.

If you want to put your pool on grass, it is recommended to lay a ground cloth. This way you protect your pool against sharp things that can be in the bottom.

How many pool tiles do I need?

Now assume that you have a swimming pool of 2 by 2 meters.

To calculate the number of pool tiles required, do the following:

You need 2 tiles per strip of 5 meters (in case 1 tile has a length of 40 cm: 200 cm / 40 cm = 5 pieces). Five of these strips next to each other makes 5 × 5 = 25 tiles.

Suppose there are six tiles in one package, then you need at least 5 packages.

It is always recommended to order some extra tiles, in order to create a beautiful edge around the pool.

Conclusion

As you have read, swimming pool tiles are indispensable if you have or are going to buy a swimming pool.

Swimming pool tiles not only protect your pool against cracks, but also your whole family against unsightly falls.

Choose the right pool tiles for the surface on which your pool will be placed, and you will enjoy your pool for years to come!
