85 Gallon Reptile Tank 48in x 24in x 18in - Front Opening Enclosure

Our review of the 85 Gallon Reptile Tank finds it best suited for reptile keepers who need a roomy, easy-to-maintain enclosure without heavy, complicated assembly. The single biggest reason to buy is simple: this terrarium combines a true 48in x 24in footprint with front-opening tempered glass doors so cleaning, feeding and routine checks are far less fiddly than with top-access boxes. For anyone building a bioactive setup or housing large snakes, bearded dragons or multiple lizards, the size and features make this tank a practical long-term choice.

Key Features

• Generous interior: The 48in x 24in x 18in dimensions provide ample floor space for bioactive substrates, hides and climbing features so reptiles can move and thermoregulate naturally.
• Front-opening access: Tempered glass sliding doors with included handles let you clean and feed from the front without suction cup hassles or awkward reach-ins.
• Secure build: A fully closed structure with a 2mm door gap minimizes escape risk and uses rigid tempered glass that resists scratching.
• Top ventilation: Screen top with about 28% blockage keeps the enclosure well lit and compatible with heat lamps, UVA/UVB fixtures and humidifiers.
• Lightweight yet sturdy: The design is easy to assemble in six steps and is lighter than heavy wooden cabinets while remaining stable for everyday use.
• Stackable option: Compatible with stackers and spacer cabinets for anyone wanting to build multiple enclosures into a compact rack.

Who It's For

This enclosure is ideal for hobbyists building a dedicated reptile room, keepers wanting a secure snake tank with easy front access, and anyone planning a bioactive substrate who can add a secondary silicone bead for leakproofing. The size is especially helpful for adult snakes and medium to large lizards that need floor space rather than height.

It is less suitable for aquatic or semi-aquatic reptiles because the product is not guaranteed leakproof without additional sealing, and owners seeking fully waterproof glass aquariums should look elsewhere. Very tall arboreal-only species that need more vertical space will also want a taller enclosure.

Pros & Cons

Pros

• Spacious 48in x 24in floor area gives plenty of room for bioactive setups and enrichment.
• Front sliding tempered glass doors make feeding and cleaning quick and convenient.
• Well-ventilated top with low blockage keeps heat and light accessible for common reptile equipment.
• Lightweight construction and straightforward six-step assembly make handling and setup easier.

Cons

• Not guaranteed leakproof; bioactive builds require you to double-seal the seams with silicone for water security.
• Height is moderate at 18in, so it is not ideal for tall arboreal-only species that need extra vertical space.
