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.

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.

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!
