Two cup-shaped bubblers, two very different interpretations of a chilled session. The GRAV Slush Cup delivers the familiar cup-and-straw look with conventional water filtration. The Freeze Pipe Slush Cup takes that theme into the body itself, sealing freezable glycerin inside its walls. That is the feature that gives Freeze Pipe our vote.
What GRAV does well
GRAV has made the Slush Cup a recognizable design. Its seven-inch body, angled straw and reinforced cross-cut downstem create a compact water pipe that fits naturally into the cup-shaped format. There is no cooling chamber to freeze, so setup is simply filling the piece and preparing the bowl.
The Freeze Pipe difference
Freeze Pipe places glycerin in the walls of the body rather than attaching a coil on top. The design pairs that cold surrounding chamber with a double showerhead perc and a fused straw mouthpiece. For someone who likes the concept of a slush cup, this adds a functional connection to the name: a body you actually chill before use.
Which is easier to live with
GRAV is the straightforward choice if you want a conventional cup bubbler that is always ready. Freeze Pipe calls for freezer preparation according to its instructions. In return, you get its cooling feature without assembling a separate neck or stacking another attachment onto the piece.
Our pick
We prefer the Freeze Pipe Slush Cup for buyers who want the playful format to offer more than a distinctive silhouette. GRAV deserves credit for its established design, but Freeze Pipe gives the cup category a clear additional benefit through its glycerin-filled walls.
