Rank #7 in Best Reptile Vivarium 2026: 10 Ranked, and the Tank Volume Fields That Don't Add Up
PawHut Glass Reptile Terrarium, 30 x 30 x 45 cm, 40L
Price and rating as shown on Amazon when we collected them. Both change.
PawHut's glass terrarium is a 30 x 30 x 45cm enclosure sold as a 40L vivarium for tortoises, priced at £62.99 and rated 4.6 out of 5 from 114 ratings. It takes seventh place in this guide. It is also the listing that breaks the pattern the rest of the guide describes: its capacity number is the one that adds up.
The Tank Volume field reads 40,500 cubic centimetres, and the listed dimensions of 30 x 30 x 45cm come to exactly 40,500cm³ — 40.5 litres. Unlike the 4ft tank whose volume field claims six times its real capacity, or the arboreal listed as 4.8cm tall with a volume of 576 cubic inches, there is nothing here to reconcile between the volume field and the size of the box. The oddities sit elsewhere. Included Components reads 'Drainage Hole', which is a feature rather than an extra in the box. The bullets promise a top mesh wire lid with a lock and call the design escape-proof, while three of the four reviews quoted on the listing mention gaps around the doors. And the final bullet, labelled 'Bearded dragon tank dimensions', describes the same 40L enclosure that the first bullet offers to lizards, frogs, snakes, turtles and tortoises. Everything on this page comes from the Amazon listing, not from our own testing.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Great enclosure. Has a hole to the bottom rear for any wiring along with top holes for thermostat probe etc. it is heavy but great quality. Would buy again and recommended”
Verified purchase“The media could not be loaded. I love this little tank, I have 5 now, housing my praying mantis and jumping spiders. The gap around the door is quite big, so smaller bugs may escape. Still a good tank. Well worth the price. The removable lid helps for cleaning. Comes fully assembled. Would recommend this item.”
