Main Feature: Double Showerhead Percolator System

The standout feature of this Castle Glassworks bong is its two showerhead percolators positioned in the tube. Combined with the lower beaker chamber, this design creates a multi-stage water path that helps cool and filter smoke before it reaches the mouthpiece.

Large 18" Beaker Bong Design

At 18" tall, this bong fits the large bong category and gives customers a bigger chamber, taller tube and stronger tabletop presence than smaller compact water pipes. The beaker base adds the familiar wide-bottom shape that many shoppers prefer for stability and water capacity.

7 mm Tube with 12 mm Thick Base

The 7 mm tube gives this piece a thicker feel than many standard glass bongs, while the 12 mm thick base and 5" wide footprint help keep the piece grounded during regular tabletop use.

Borosilicate Glass Construction

Made from borosilicate glass, this Castle Glassworks bong is designed for regular water pipe use and easier cleaning compared with many non-glass materials. Borosilicate glass is a popular choice for bongs because it handles heat well and keeps the piece looking clean when maintained properly.

Included Downstem and Bowl

This bong includes a coloured glass 19 mm downstem and 14 mm bowl, giving customers the main setup pieces needed for dry herb use where permitted. Always confirm replacement part sizing before ordering additional bowls, downstems or adapters.

Who Is This For?

The Castle Glassworks 18" Double Showerhead Beaker Bong is best for intermediate to experienced users who want a larger beaker bong with more filtration than a basic single-chamber water pipe.

It is also a strong option for customers shopping for large glass bongs, percolator bongs, showerhead perc bongs, thick base bongs or an 18-inch bong with a more advanced tube design.

Care and Cleaning

Because this bong uses multiple chambers and two showerhead percolators, regular cleaning is important. Empty old water after use and rinse the beaker base, tube and perc sections before residue has time to settle.

Remove the downstem and bowl before deeper cleaning. Use a cleaner suitable for borosilicate glass and avoid forcing brushes or tools into the showerhead percs. Allow all glass parts to dry fully before reassembling or storing.

Responsible Use, Legal Age & Glass Safety

This glass water pipe is intended for responsible adult use only with legal smoking material where permitted. Legal age and cannabis laws vary by location, so customers are responsible for knowing and following their local rules before use.

Do not drive, operate machinery or perform safety-sensitive activities while impaired. Handle glass carefully, avoid forcing incompatible parts together, clean the chamber and accessories regularly, and store the piece securely away from children, pets and fragile surfaces.
