Frequently Asked Questions — Castle Cannabis Accessories
Are Castle Glassworks accessories compatible with other bongs?
Most of our downstems, bowls, and ash catchers use standard 14mm joints and are compatible with a wide range of bongs from other brands. Always check the joint size and length listed in each product description before purchasing.
Do Castle Glassworks 18 inch bongs have an ice catcher?
Yes. All 18 inch Castle Glassworks bongs include built-in ice catchers that hold ice cubes, cooling the smoke even further before inhalation.
What is the Double Showerhead bong?
The Double Showerhead 18" Beaker Bong features two stacked showerhead percolators inside the chamber — each distributes smoke through dozens of tiny holes, creating exceptional diffusion and the smoothest possible hit in the Castle Glassworks range.
Does Castle Glassworks ship 18 inch bongs across Canada?
Yes. All Castle Glassworks orders ship to every Canadian province and territory. Orders over $50 qualify for free shipping across Canada and the USA. Most orders dispatch within 1–3 business days.
