The Upline® Hammer Bubbler is 5" tall and made on 38mm tubing. Its ladder perc restrictions create bubbler chambers that wash and filter smoke. Its fission downstem diffuses smoke through water and is fixed inside the bubbler to prevent damage. Two glass feet stabilize the bubbler between uses, and its carb and mouthpiece are ergonomically designed. No accessories are necessary for using this bubbler, and it works best with approximately 1" of water.

A massive bubbler that can also be mistaken for an actual hammer

It is a behemoth. Feels more like a weapon than a bubbler. But fortunately it is the smoothest bubbler you’ll find. An awesome party piece with a massive bowl head. Burly.


Really awesome and unique bubbler. Love the size and the look. The mouth piece is really cool and feels super well designed. When people come to my house they always gravitate towards this piece because it really stands out.
