Rock Glass 7" Bong | Showerhead Perc & Submerged Downstem

The Rock Glass 7" Bong is a compact clear-glass water pipe built around an integrated showerhead percolator and a submerged downstem. The clear construction is functional as well as aesthetic: you can see the water level, watch the diffusion working, and spot when the piece needs cleaning.

At seven inches it is small enough to store and handle easily, while still holding enough water for genuine filtration rather than the token amount a mini rig manages.

Best for: two-stage filtration in a compact clear-glass piece

Product Specifications

Why Choose This Bong

Smoke first passes through the submerged downstem, which breaks it up as it enters the water, then travels into the showerhead percolator for a second round of diffusion. Two stages mean more total contact between smoke and water, which strips more heat before the smoke reaches the mouthpiece. Clear glass makes the whole process visible and makes maintenance obvious, so the piece is less likely to be neglected.

Ideal For

This bong suits anyone who wants two genuine filtration stages in a piece compact enough to store, clean and travel with easily. It's a strong upgrade from a single-downstem bong without stepping up to a full-size showpiece.

Care & Maintenance

Change the water every few sessions. For a full clean, use isopropyl alcohol with coarse salt as an abrasive, cap the openings, shake, then rinse thoroughly with warm water. Never pour hot water into cold glass.

Frequently Asked Questions

How tall is this bong?
Seven inches, matching the rest of the Rock Glass 7" range.

What is the benefit of a submerged downstem?
A submerged downstem sits below the waterline, so smoke is forced through water immediately on entry rather than passing over the surface. It adds a diffusion stage before the percolator does its work.

What else do I need to get started?
A bowl and a lighter cover the basics. Ash catchers and cleaning supplies extend the life of the piece.
