Glass vs PVC Enclosures for Leopard Geckos
Heat and humidity retention
PVC and melamine panels insulate significantly better than glass, meaning the heating equipment doesn't have to work as hard to maintain a stable gradient, and ambient humidity holds more consistently — a real advantage for bioactive or naturalistic builds.
Cost and availability
Glass tanks are widely available, often cheaper, and easy to find secondhand. PVC and melamine enclosures, especially front-opening designs built for reptiles specifically, tend to cost more and may need to be ordered rather than picked up locally.
Weight and durability
PVC enclosures are generally lighter than an equivalent-sized glass tank and more resistant to cracking, which matters for larger setups or anyone who might need to move the enclosure.
Visibility and access
Glass tanks offer full 360-degree visibility, which some keepers and observers prefer. Most PVC enclosures use front-opening doors, which are also generally considered less stressful for the gecko to access than a top-opening lid, since access doesn't come from directly overhead.

A single adult leopard gecko needs a 20-gallon long tank as an absolute minimum, with a 36x18 in (40-gallon breeder) footprint now considered the recommended standard — plus a secure lid, an under-tank heater on a thermostat, a thermal gradient, at least three hides, and a shallow water dish.
Set up in this order: substrate, then heat source wired through a thermostat, then hides and water dish, then decor — and run the whole enclosure for at least 24–48 hours to confirm stable temperatures before your gecko moves in.
Hatchlings can start in a 10-gallon tank or tub, juveniles do well in 20 gallons, and adults need a 20-gallon long as an absolute minimum — with 36x18 in (40-gallon breeder) now the widely recommended standard, not just an upgrade.
Heat a leopard gecko enclosure with an under-tank heater and/or overhead heat source (halogen or deep heat projector) wired through a thermostat — a thermostat is mandatory, not optional, and heat rocks should never be used.
Leopard geckos can survive without UVB using dietary D3 supplementation, but current husbandry guidance now recommends low-level UVB (roughly 2–6% T5) as best practice — it improves D3 synthesis, bone density, and natural behavior, and views on it have shifted significantly from older nocturnal-species advice.
Keep ambient humidity around 30–40% across most of the enclosure, with a dedicated humid hide raised to roughly 70–80% to support smooth, complete sheds.
