GRAV 5″ Glass Mini Hammer Bubbler

Compact yet highly functional, the GRAV® 5" Glass Mini Hammer Bubbler offers the smoothness of water filtration in a portable handheld piece. Its hammer-style shape sits comfortably in the hand while the flat base helps keep the bubbler stable between sessions.

Made from thick borosilicate glass, this compact bubbler is designed for durability and clean flavor. The integrated water chamber helps cool and filter smoke for a smoother draw compared to traditional dry pipes, making it an excellent choice for both newer users and experienced glass enthusiasts.

Sized for convenience without sacrificing performance, the GRAV® Mini Hammer Bubbler is ideal for solo sessions, smaller setups, and everyday rotation.

We love the GRAV® Mini Hammer Bubbler because it delivers the smoothness of water filtration in a compact, sturdy, comfortable, and easy-to-use piece. The chunky hammer base adds stability, while the colorful finishes and clean design give it personality without sacrificing functionality. It’s a great balance of portability, durability, and smooth performance.

Fill the bubbler with a small amount of water—just enough to cover the downstem openings without causing splashback. Empty and rinse regularly to maintain clean flavor and smooth airflow.

For deeper cleaning, use isopropyl alcohol and coarse salt or a glass-safe cleaning solution. Rinse thoroughly with warm water and allow the piece to dry completely before reuse.

Handle with care and store on a stable surface when not in use.
