Exo Terra Water Dish, Water Bowl for Reptiles, Large, PT2803 Review (2026)
Updated September 21, 2026 · Research-based review
Our verdict
Exo Terra's Large Water Dish, PT2803, is a food-grade resin bowl about 8.8 by 7.1 by 2.2 inches with a textured rock exterior and built-in steps so smaller animals can climb out. It holds enough water for snakes and bigger lizards to soak before a shed, but that surface area raises humidity, which can bother desert species.

Material and finish
Exo Terra molds this water dish from food-grade resin, with a textured, rock-like finish on the outside that is meant to blend into a naturalistic terrarium rather than look like an obvious plastic bowl. The inside surface is smooth and coated, which Exo Terra designs specifically to resist bacterial buildup and to make the dish easier to rinse clean between water changes than an unglazed or rough-textured bowl would be. At roughly 8.8 by 7.1 by 2.2 inches, the Large size holds a meaningful volume of water while staying low and wide enough that most reptiles can step in and out without difficulty, and Exo Terra builds the base to be stable enough that it resists tipping even when a larger lizard or snake climbs partly into it.
Built-in steps for smaller animals
One detail Exo Terra highlights on this dish is a set of shallow steps molded into the interior, meant to give crickets, roaches, and other small feeder insects or terrarium animals a way to climb back out if they fall in, rather than drowning in a bowl with smooth vertical sides. That detail matters more in enclosures that house live feeder insects loose in the terrarium between feedings, since an insect that falls into a plain bowl often cannot get out on its own. The steps do not meaningfully reduce the dish's water capacity or its usefulness as a soaking bowl for the reptile itself, so the feature adds a safety margin for smaller tank mates without giving anything up for the animal the dish is primarily there to serve.
Using it as a soaking bowl
The Large size gives snakes and bigger lizards enough room to submerge a significant portion of their body, which is useful around shedding time, when soaking helps loosen old skin and makes a clean shed more likely, especially for snakes prone to retained shed on the tail or eye caps. It also works as a simple drinking source for species that prefer standing water over misted droplets or drip systems, and the wide, low profile makes it easy for an animal to find and use without needing to climb over a raised lip. For species that regularly soak, such as ball pythons or larger monitors, having a dish sized for that use is more practical than a small dish meant only for drinking.
Humidity and cleaning tradeoffs
A water surface this large evaporates more actively than a small drinking dish, which raises ambient humidity in the enclosure over time, a side effect that works in favor of species from humid habitats but can push humidity higher than desert species like bearded dragons or leopard geckos actually want. Keepers of arid species should weigh that against the soaking benefits, and may prefer a smaller dish or one placed away from the main basking area to limit the humidity effect. The dish is also noticeably heavier once filled, and its size and weight can make it awkward to lift out and carry to a sink for cleaning without spilling, so keepers may find it easier to siphon or scoop water out first rather than moving a full dish.
Bottom line
Exo Terra's Large Water Dish is a sturdy, food-grade resin bowl well suited to snakes and bigger lizards that benefit from soaking, with a coated interior that is easy to keep clean and built-in steps that give small feeder insects a way out. It is the wrong choice for desert species kept at low humidity, since a bowl this size can push ambient moisture higher than those animals need, and its size makes it heavier and more awkward to clean than a smaller dish. For humid-tank species and animals that regularly soak, the tradeoffs are worth it.
