What goes on the floor and inside the enclosure shapes your reptile’s day as much as the lamps do. The right substrate lets it dig or stay clean, hides let it feel safe at every temperature, and climbing and clutter give it places to explore. This guide covers each of those, the honest state of the loose substrate debate, and a cleaning routine that keeps the whole setup healthy.

Substrate types
| Substrate | Best for | Pros | Cons |
|---|---|---|---|
| Paper towel or newspaper | Quarantine, sick animals, new arrivals | Cheap, easy to see waste, easy to replace | No digging; must be changed as soon as it is wet |
| Slate or stone tile | Dry species | Easy to lift and clean, holds warmth | No digging |
| Soil mixes | Most lizards and snakes | Holds burrows and some humidity, looks natural | Needs mixing, packing and drying |
| Bioactive soil | Experienced keepers | Living cleanup crew breaks down waste | Most planning and setup |
Paper and tile
The MSD Veterinary Manual calls newspaper the substrate of choice for sick reptiles, and VCA lists newspaper, butcher paper and towels as easy-to-clean options for snakes. ReptiFiles recommends paper towels for quarantine, and notes that they must be replaced as soon as they are wet and do not let the animal dig. It says stone tile is easy to remove and holds warmth well.
Paper is the right start for any new or sick animal, because you can see every dropping and nothing can be swallowed. It also makes it easy to spot mites, blood or a missed meal during the first weeks.
Soil mixes
Most species do well on a soil-based floor once they are settled and healthy.
- Dry species: ReptiFiles’ semi-arid mix for leopard geckos is 60% organic topsoil, 30% sand and 10% clay (such as Excavator Clay), moistened, packed firmly and left until completely dry. It suggests a depth of at least 4 inches (10 cm) for burrowing.
- Corn snakes: the RSPCA suggests 60% soil, 30% sand and 10% leaves, with the leaves sterilized in boiling water and dried first.
- Royal pythons: the RSPCA recommends organic reptile soils that hold humidity without going moldy, and says to avoid sand on its own, which may irritate the skin.
Use plain topsoil with no fertilizer or added chemicals, and washed play sand rather than colored or “calcium” sand.
Burrowing clay (US)
Zoo Med Excavator Clay Burrowing Substrate, 10 lb
A natural clay substrate with no dyes. Mixed with water and shaped, it dries hard and holds tunnels without collapsing. ReptiFiles lists it as one part of a packed sand, soil and clay mix.
- Weight
- 10 lb
- Type
- Clay burrowing substrate
- Holds shape
- Tunnels do not collapse once dry
- Additives
- No dyes or chemicals (per Zoo Med)
Best for
Keepers who choose a packed, diggable naturalistic floor after reading both sides of the substrate debate.
Worth knowing
Loose substrate is debated: VCA advises paper-based flooring, while ReptiFiles and the RSPCA accept packed sand or soil mixes. Never use it for a sick or injured dragon.
Coconut fiber soil (US)
Zoo Med Eco Earth Coconut Fiber Substrate (3 bricks)
Compressed coconut fiber bricks that expand in water into a loose, soil-like substrate that holds moisture well.
- Pack
- 3 compressed bricks
- Each brick makes
- About 7 to 8 liters
- Material
- Coconut fiber
Best for
A humidity-holding base layer, alone or mixed with coconut husk chips.
Worth knowing
ReptiFiles rates it as acceptable rather than ideal because fine fibers can stick in heat pits. Keep it damp, not soggy.
Terrarium soil (UK)
Exo Terra Plantation Soil, 8.8 L
A ground coconut husk substrate from Exo Terra that holds moisture and can be dug into.
- Volume
- 8.8 L per pack
- Material
- Coconut husk fiber
Best for
A humidity-holding substrate in a UK vivarium.
Worth knowing
Several listings exist (loose bags and compressed bricks). Check the volume, and keep it damp rather than wet.
Bioactive
A bioactive floor adds live plants, leaf litter and a cleanup crew of springtails and isopods. ReptiFiles says these animals break down organic matter and return nutrients to the soil, and that springtails can build a stable population in a few weeks. ReptiFiles recommends bioactive mainly for experienced keepers. See the enclosure types guide for the basics.
Loose substrate and impaction: both sides
Impaction is a blockage in the gut, and swallowed substrate is often blamed. The sources split:
The cautious view. The MSD Veterinary Manual says sand, gravel and corncob are generally not recommended because they are easily swallowed, and that snakes should not be fed on loose substrate for the same reason. VCA says never to use coarse sand, corncob or crushed walnut shell for leopard geckos, and advises against sand and gravel for snakes except burrowing species.
The husbandry view. ReptiFiles argues that impaction is almost always caused by poor care, such as an enclosure that is too cold, or by illness. It says sand can be safe for leopard geckos, but only when used correctly, mixed with soil and clay and packed down, and only for healthy animals that have finished quarantine.
Where they agree. Every source here puts sick or newly arrived animals on a plain, solid surface such as paper. And the husbandry view itself names the real risk factors: an animal that is too cold or unwell is the one most likely to have trouble, whatever it lives on.
Our approach: start new animals on paper, keep temperatures right, and if you move to a loose floor, use a packed soil mix rather than pure sand. Feed snakes and lizards from tongs or a dish rather than off the floor.
Substrates to avoid
- Cedar and pine shavings. The MSD Veterinary Manual says they contain odor-emitting oils; VCA says cedar is toxic to reptiles.
- Corncob. Easily swallowed and, says the MSD manual, tends to go moldy when wet.
- Calcium or “vita” sand. ReptiFiles warns it can neutralize stomach acid.
- Walnut shell. VCA and ReptiFiles say avoid. The MSD manual lists walnut bedding among materials used for some species; we leave it out.
- Cat litter and gravel. VCA advises against them for snakes.
- Coconut fiber for dry species. ReptiFiles does not recommend coconut coir or husk for leopard geckos. It is widely used for humid species such as ball pythons, where holding moisture is the point, so match the substrate to the species rather than using one for everything.
Hides: warm, cool and humid
Hides are not decoration. A reptile that cannot hide at the temperature it needs has to choose between feeling safe and being warm.
- At least two hides, one at each end. The RSPCA says this lets the snake choose its temperature and still feel secure. For royal pythons it recommends several hides at both ends.
- A humid hide with damp moss inside. The RSPCA suggests one with moist moss for royal pythons, and VCA recommends moist material such as wet sphagnum moss for leopard geckos. Check the moss every few days and replace it if it smells or goes moldy.
- Snug, not roomy. The RSPCA says a hide should be tight enough that a coiled snake’s body touches the sides.
Small hide
Exo Terra Gecko Cave
A natural-looking resin cave with a low entrance, made in several sizes. Easy to wash, and it can be used as a warm, cool or humid hide.
Best for
One of the three hides; buy one per zone.
Worth knowing
Choose a size the gecko can turn around in while touching the walls. Too large a hide feels less secure.
Large hide
Exo Terra Reptile Cave, Large
A heavy resin hide with a natural rock look and a wide, stable base, so a large lizard cannot tip it over.
- Size
- Large
- Material
- Resin
- Base
- Wide and stable
Best for
The cool-end hide where a dragon sleeps and retreats.
Worth knowing
Check that an adult can turn around inside. A grown dragon may need the extra-large size.
Moss for the humid hide
New Zealand Sphagnum Moss
Dried long-fiber moss that soaks up and slowly releases water. Damp moss inside a hide makes a humid hide for shedding.
- Type
- Long-fiber sphagnum
- Use
- Humid hide, top layer
Best for
Filling one hide with damp moss, as ReptiFiles suggests, to help sheds come off in one piece.
Worth knowing
Replace it often so it does not go moldy.
Climbing and clutter
An empty enclosure with one hide is stressful. The RSPCA asks for plenty of cover for royal pythons, and says corn snakes climb well and should have branches or peg boards. Even ground-dwelling lizards use low rocks and branches.
- Fill the space. Branches, cork bark, rocks and plants break up open floor and give routes between hides.
- Sterilize natural wood. The RSPCA says to treat natural branches with boiling water first.
- Make it stable. Rest rocks on the enclosure floor, not on top of substrate, so a digging animal cannot be trapped underneath.
- Mind the lamps. Keep climbing decor low enough that the animal cannot reach a bulb, or touch the mesh right under it.
Plants: real or artificial?
Artificial plants are easy to wash and cannot be eaten, so they are a safe default.
Live plants add humidity and cover and are part of any bioactive setup. ReptiFiles keeps a list of reptile-safe plants. It notes that herbivores and omnivores are the most likely to graze on them, and that even insect eaters can be affected, because feeder insects nibble plants before they are eaten.
- Choose plants from a reptile-safe list, and check the species name before buying.
- Buy plants grown without pesticides where you can, rinse the leaves, and consider repotting into plain soil before planting.
- If you are not sure a plant is safe, use an artificial one instead.
Water bowls
- Heavy and stable. VCA recommends a large, heavy ceramic bowl that will not tip over.
- Large for snakes. The RSPCA asks for a large bowl at the cool end for royal pythons.
- Fresh water often. The RSPCA says change it at least daily and immediately if fouled. VCA says clean and disinfect bowls every 24 to 72 hours, and the MSD Veterinary Manual says at least once a week. Daily refills with a regular scrub covers all three.
Water bowl (US)
Zoo Med Repti Rock Water Dish, X-Large
A heavy, shallow plastic water dish with a smooth, easy-clean surface, wide enough for a ball python to drink and soak.
- Size
- About 11 in across, 2 in deep
- Material
- Plastic
- Model
- WD-50
Best for
The main water bowl on the cool side of a US setup.
Worth knowing
Snakes often soil their water. Clean it as soon as it is dirty.
Corner water bowl (UK)
Exo Terra Corner Water Dish, Extra Large
A resin corner water dish with a pebble finish and built-in steps, sized for larger reptiles to drink and soak.
- Size
- Extra large
- Material
- Resin
- Feature
- Steps to climb out
Best for
The main water bowl on the cool side of a UK vivarium.
Worth knowing
Fits a corner, so it suits square-cornered vivariums best. Clean it as soon as it is soiled.
Cleaning and disinfecting
Sources agree on the pattern, if not the exact timing:
| Task | How often | Source |
|---|---|---|
| Remove droppings, urates and uneaten food | Daily, or as soon as you see them | RSPCA, MSD; VCA says every 24 to 72 hours |
| Replace substrate | At least monthly (non-bioactive) | MSD |
| Full clean with disinfectant | Monthly (RSPCA); at least every 3 months (MSD) | RSPCA, MSD |
How to disinfect safely:
- Move the reptile to a secure tub.
- Remove all decor and substrate. Scrub off dirt with hot water first, since disinfectant labels expect a surface that is already clean.
- Use a reptile-safe disinfectant at the dilution on the label. The MSD Veterinary Manual advises asking your vet which disinfectant suits your setup.
- Rinse well, as the RSPCA advises, and let everything dry fully before the reptile goes back.
Wash your hands before and after handling your reptile or its equipment. The RSPCA reminds keepers that reptiles can carry salmonella.
Reptile-safe disinfectant
F10SC Veterinary Disinfectant Concentrate
A concentrated veterinary disinfectant that you dilute with water. Sellers describe it as non-corrosive and non-irritating at working dilution and list cages, hard surfaces and food and water bowls among its uses.
- Form
- Concentrate, mix with water
- General use
- 1:500, about 2 ml per liter (per seller listing)
- Higher level
- 1:250, about 4 ml per liter (per seller listing)
Best for
The full clean-out of an enclosure and its decor, and disinfecting water bowls.
Worth knowing
Follow the dilution on your bottle. Remove the animal first, clean off dirt before you disinfect, and let surfaces dry before it goes back. F10SC and F10 CL are different products with different dilutions.
By species
- Leopard gecko supplies
- Bearded dragon supplies
- Ball python supplies
- Crested gecko supplies
