Create a truly naturalistic, underground retreat for your reptile with this Underground Humid Hide System, designed to be fully buried beneath the substrate while still offering easy access, visibility, and optimal humidity for healthy sheds.

This innovative hide mimics how reptiles would seek shelter in the wild, providing a dark, secure space below the surface with customizable tunnel entrances that lead back up to the enclosure floor. Thoughtfully engineered for both reptile comfort and keeper convenience, this is a next-level upgrade for bioactive and naturalistic setups.

⚠️ Please double-check sizes before ordering to make sure your reptile will fit!

🧪 Unique Features

🕳️ Fully Underground Design

Designed to sit completely beneath the substrate, this hide allows your reptile to burrow down into a secure, humid microclimate — perfect for shedding and stress reduction.

📦 Three-Piece Construction

Base Hide Chamber — cozy and secure resting chamber
Removable Moss Compartment — holds damp moss above your reptile
Lift-off Lid with Handle — allows easy access for misting, cleaning, moss replacement, or to get to your reptile

🌱 Humidity-Friendly Base

Small holes around the base allow moisture from the surrounding substrate to naturally wick into the hide, supporting consistent humidity levels underground.

🛤️ Modular Tunnel System

Each entrance connects to interchangeable underground tunnels:

Straight Tube – Direct access runs
Elbow Tube – Right-angle turns for flexible layouts
Curved Tube – Designed to rise smoothly up to the surface

Create custom pathways that fit your enclosure layout and substrate depth. If an orientation is selected WITHOUT a back entry way, only one set of 1 straight and 1 curved tubes will come with your order.

↔️ Orientation & Entrance Options

Choose left or right entrance orientation
Optional second rear entrance for multi-exit hides or shared pathways

👀 Optional Viewing Peep Hole

Add a front peep hole to discreetly check on your reptile underground without disturbing them. Includes a personalizable magnetic cover plate for the outside of the enclosure. The color of the text will be either black or white depending on the contrasting color chosen for the hide.

⚠️ Important: The magnetic plate works only if the hide is fully flush against the enclosure wall on the peep-hole side.

🌬️ Health-Conscious Design

The moss tray suspends moisture above your reptile, helping create a humid microclimate below — reducing direct contact and the risk of scale rot.

🧷 Safe & Durable

Made with strong, moisture-resistant PETG and designed with smooth, rounded edges. No sharp parts — just safe, cozy comfort.

📝 Tip

If your reptile is near the upper limit of a size range, consider sizing up — especially during shedding cycles when a bit of extra humidity and room goes a long way!

💡 How It Works

Add damp sphagnum moss or your preferred moisture-holding material to the inner tray.
Replace the lid with the bow to trap moisture inside the hide.
Position the hide on the cooler side of your enclosure for best results.

Humidity levels may vary depending on enclosure size, ambient room conditions, and the moss or substrate used.

🛒 How to Order & Choose Your Options

This hide is fully customizable. Please follow the steps below to ensure you receive the correct size and configuration for your enclosure.

1️⃣ Choose Your Size

Select the size based on your reptile’s body size and available underground space:

Small – Best for hatchlings and small-bodied reptiles
Medium – Ideal for juveniles and medium-sized species
Large – Designed for adult ball pythons and reptiles that prefer extra room

📏 Full dimensions for each size are listed in the “Available Sizes” section above.

2️⃣ Choose Your Entrance Orientation

This determines where the main tunnel connects to the hide when facing the front of the hide.

Left – Main entrance on the left side
Left w/ Back Entry – Left side entrance plus a second entrance on the back
Right – Main entrance on the right side
Right w/ Back Entry – Right side entrance plus a second entrance on the back

🛤️ Back entrances are great for:

Multi-tunnel layouts
Larger enclosures
Creating multiple access points underground

Note: The reason it costs more for an orientation with the additional back entry way is because that will come with an additional set of 1 straight and 1 curved tube.

3️⃣ Peep Hole Option (Optional)

Choose whether you would like to add a front viewing peephole to your underground hide.

Yes – Add a front peephole with a magnetic cover plate
No – No peep hole included

⚠️ Important: The peep hole should only be selected if the hide will sit fully flush against the enclosure wall on the peephole side so the magnets function properly.

4️⃣ Peep Hole Cover Text (Optional)

If you selected Yes for the peephole option above, you may add custom text to the magnetic cover plate.

Enter the text exactly as you want it to appear (it will be converted to ALL CAPS)
The text color will be black or white, chosen automatically for best contrast

If no text is entered, the cover plate will be sent blank.

⚠️ 3D Printing Disclaimer

This item is individually 3D printed, making each hide truly one of a kind! While we work hard to produce clean, high-quality prints, minor surface variations such as faint lines or tiny bumps are a normal part of the 3D printing process.

We do our best to minimize or prevent these flaws through careful printing and post-processing, but because every print is unique, a completely flawless surface cannot be guaranteed. Thank you for understanding and appreciating the handmade nature of 3D printed art!
