Best Substrate For Bearded Dragons

By June 20, 2018Reptiles

When it comes to choosing the best substrate for bearded dragons, there are two basic types to choose from. There are pros and cons to both types, and with conflicting information out there it can be difficult to make an informed choice.

Which means that all you can do is educate yourself on all the substrate options out there, and then  make the best personal decision on the best substrate for your bearded dragon based on it.


The first type, particle substrates, allow a bearded dragon to dig, which is something they do naturally and can be emotionally beneficial. However, you do need to consider the following potential problems with particle substrates:

  • There is a risk of impaction from ingestion
  • Particle substrate is more difficult to keep clean
  • There is a risk of infection from bacteria growing

However, you shouldn’t get too hung up on their need to dig. Bearded dragons come from an environment where there is actually an incredible amount of rocky terrain and not a lot of sand at times, so although it’s nice thing to provide them, it’s not something that is essential to their well-being.

The second type, non-particle substrate, usually comes in a roll of fabric material that you simply lay on the floor of your bearded dragons terrarium. They are easy to clean, but again you have negatives to consider:

  • The claws of the bearded dragon can sometimes get caught in them
  • A separate digging source will have to be considered
  • When you wash them you will need a second while it is drying

So there are pros and cons to both basic types, and it is very much personal choice in determining what you consider to be the best substrate for bearded dragons. In fact, trial and error with different types over weeks and months will help you work out what’s best for your pet.

To help you to make an informed decision, we’ve put together a bearded dragon substrate buying guide, giving you a quick overview of the main types available.

On top of that, we are also going to take a detailed look at five high quality bearded dragon terrarium substrate products, reviewing each one in depth to help you in deciding which type to consider for your pet.

Bearded Dragon Substrate Types: Buying Guide


When it comes to considering the use of sand or clay as the substrate for a bearded dragon terrarium, there is far more to it than you would at first think.

In terms of sand, there are several different types to consider. You can use everyday sand that has not been refined in any way, but there are also more specialist types available now such as calcium sand and special colored sands that may work better.

Normal sand contain a lot of variation in what it contains and if ingested could cause problems. So just grabbing a bag builder sand or place and is not a great option, however attractive it seems due to the low price.

The problem with calcium sand is that contains a high proportion of calcium carbonate. One potential side effect is that if it ingested it can neutralist stomach acids, making food digestion more difficult.

Colored sands also suffer from the same ingestion problems, as well as having the potential to stain the skin of your bearded dragon, which is obviously not ideal.

Clay is a slightly better choice than sand, especially in terms of giving the dragon something to dig in. However on the downside it can be incredibly difficult to keep clean.

Specialist clay products allow burrowing that retains its shape, so that your bearded dragon can create tunnels, however it can become quite expensive to constantly provide enough clay to achieve this, while keeping it clean. On top of that it can harden and require regular dampening soften the reshaping and reuse.

Reptile Carpets

A popular choice of non-particle substrate are special reptile carpets. These basically come as a roll and are often felt or a similar fabric. However, there are more advanced forms around now which have a simulated sand texture on them.

These carpets are ideal for bearded dragons in terms of cleanliness and convenience, but they can be problematic in terms of digging. There have been issues with dragons getting their claws stuck in them, and unless an alternative digging source is provided then they can get ripped up quite quickly.


Some bearded Dragon owners use newspaper, or specially designed paper-based lining products.

These can be affordable and practical. You don’t have to worry about impactation, and it’s a practical substance for digging in.

However, paper-based substrate can retain humidity easily, and will need replacing very frequently. If left damp they can also become breeding grounds for bacteria.

Bark & Mulch

Some people do use bark or mulch. However it is generally not considered the best substrate for bearded dragons due to its ability to maintain humidity, making the environment more humid than it should be.

A variation on using bark is wood chips or sawdust. However these rarely provide the best substrate for bearded dragons due to sharp edges in the chips, and even in softer sawdust. This makes impaction a real possibility and more dangerous should it occur.

On top of that, sawdust and even rough chip can become compacted when damp and will also retain smells easily, in addition to becoming a breeding ground for bacteria.

Ceramic Tiles

A growing trend is towards lining the base of a bearded dragons terrarium with ceramic tiles.  There are several practical advantages, including cleanliness and the absolute zero risk of impaction.

On top of that, ceramic tiles retain heat in an even and controllable way. You can also use ceramic tiles as the base on which you put a thin layer of a particle substrate to create a hybrid environment that retains heat, is clean, and has some variation in it over plain tiles.

However, they are a little soulless, and you will still need to provide some sort of digging option for your bearded dragon you want to allow it to have that natural outlet.
