GRAV® Hammer Bubbler — Assorted Colors

The GRAV® Hammer Bubbler is built for serious hits without sacrificing everyday practicality. Designed with a wide 38mm base, this hammer-style bubbler rests securely on your shelf and stays stable between pulls, making it a reliable companion for extended sessions or quick on-the-go breaks.

At its core is a fission downstem that diffuses smoke through 0.5 inches of water. The result is noticeably cooler, smoother draws and reduced throat heat, so you can enjoy bigger, more flavorful hits with less irritants. Crafted from borosilicate glass, the Hammer Bubbler combines clarity from start to finish with the durability needed for daily use and easy maintenance.

Available in 11 colorways (assorted colors), the Hammer Bubbler not only performs well but also looks the part—whether you’re matching it to other glass pieces or expressing your personal style. Expect vibrant hues and clean lines that fit in with a wide range of setups, from minimalist rigs to bold, color-rich collections.
