I found REPTI ZOO’s large glass reptile glass to be heavy because of the involved materials.

Nevertheless, it’s durable and can give you complete assurance that it can make your reptile friend feel at home.

One of the primary features of this terrarium is the raised bottom frame, giving room to a substrate heater you can place below.

3. PVC Panel Bearded Dragon Enclosure by Zen Habitats Review: Runner Up

Zen Habitats 4'x2'x2' Reptile Enclosures with PVC Panels

This enclosure by Zen Habitats is considered the best because of the style and durability it offers.

The galvanized steel screen as the bars is perfect for keeping the entire enclosure intact.

It’s also equipped with multiple components that make up many different enclosure features.  

I enjoyed this 120-gallon bearded dragon tank better compared to others from different brands because of the durability that it offers.

As experts suggest, the enclosure needs to be well-ventilated [1] for the beardie to have a reduced risk of respiratory infections [2] – and Zen Habitats’ PVC panel enclosure is never short in that!

Other than adult beardies, you can also house an adult sulcata tortoise, an adult python regius, an adult ball python, and many more!

Check out this video on how to properly take care of your bearded dragon:

Features and Attributes:

The enclosure is made from excellent-quality bamboo PVC panels (bamboo-printed) and is edged with aluminum for better strength and durability.

Additional features include an under-tank heater (UTH) control [3] or heat pads, which can give you the flexibility to control and regulate the tank’s internal temperature.

Due to its structure, you can use it for other pet reptiles, too, such as lizards, snakes, turtles, tortoises, chameleons, and many more!

Easy to assembleThe stainless steel mesh cover blocks substantial UVB penetration
Excellent humidity control with a humidity gaugeThe insulation is weaker because of the thin PVC cage walls
Great security for avoiding escapes

Why Choose Zen Habitat’s 4-Feet Beardie Tank?

Unlike other choices, Zen Habitat’s 4-feet enclosure offers adequate humidity levels and temperature control.

The acrylic glass panels offer the visuals along with the protection and security you’re looking for.

Expert Tips

Zen Habitat’s enclosure is perfect for adult bearded dragons. I recommend it to baby bearded dragon owners, especially those who have little knowledge about an advanced bearded dragon tank setup.

I consider this 120-gallon tank category as perfect for beginners.

It’s easy to set up, convenient to navigate for access for maintenance, and it’s just the ideal bearded dragon tank size for young adults to adult beardies.

The tank heater can also help you if the outside tank temperature affects or influences the range of temperatures in the enclosure.

What to Consider in Choosing Your 120-Gallon Beardie Tank?

In choosing the 120-gallon bearded dragon tank, you need to consider the habitat’s material, features, and setup of the enclosure.

In choosing the 120-gallon bearded dragon tank, you need to consider the habitat’s material, features, and setup of the enclosure.

1. Deciding on the Material Used

There are quite a few materials you can choose from, but the most common ones include acrylic (PVC), glass, wood, removable metal mesh, steel screens, and many more.

Your enclosure’s overall strength and durability will depend on the materials, so keep an eye out for the make.

2. Checking the Included Features

Some of the features that make a great tank include an under-tank heater (UTH), a built-in UVB light, a waterproof base substrate, removable acrylic doors, and suitable ventilation areas.

Though these aren’t all the best features, on a professional level, I’d recommend these to start with.

They’re ideal features for enclosures, especially when they’re combined with other valuable components.

3. Choosing the Setup/Theme

And who wants a plain-looking dragon enclosure? Of course, you want your bearded dragon tank set up to make it seem like your pet reptile’s natural habitat.

I would suggest a glass panel while also putting in branches, logs, rocks, and other natural materials they can climb on. You can also use wood panels to achieve a more natural look!  

There are tons of designs that go well with the 4′ x 2′ x 2′ tank size.

FAQs

Is a 120-Gallon Tank Good For a Bearded Dragon?

Yes, a bearded dragon terrarium sized at 4’ x 2’ x 2’ or 48 inches x 24 inches x 24 inches is a good size for a beardie.

It offers plenty of space for the different activities of the bearded dragon while it’s in its enclosure.

What is the Maximum Size Tank For a Bearded Dragon?

There’s no minimum or maximum-sized tank for a beardie. The ideal tank size for a regular adult bearded dragon should be at least 75 gallons.
For a slightly larger dragon, a larger tank that’s at least 120 gallons or 4’ x 2’ x 2’ is ideal.

Is a 50-Gallon Tank Big Enough For a Bearded Dragon?

Yes, a 50-gallon wood panel reptile enclosure is enough, but only for a juvenile or a baby beardie.
Adult or full-grown dragons in captivity should be housed in a 75 gallon terrarium.

In Conclusion

Choosing a 120-gallon bearded dragon tank could be complex at first. But once you become familiar with the parts, components, and features, I can guarantee that it’ll be a fun experience!

Make your pick and tailor the enclosure of your beardie, all according to what you’re looking for!
