To replace a bong bowl you only need two things: the joint size (14mm or 18mm) and the gender — a male slide for a female joint, which covers most bongs. Below you'll find glass herb slides and decorative bowls in both sizes, shipping fast from the US.
How to pick the right bowl
Match these to your bong and it'll fit first time:
Joint size
14mm the most common. 18mm on larger bongs. Measure or check your old bowl if unsure.
Gender
A male bowl (slide) drops into a female joint — that is most bongs. If your joint sticks out, you need a female bowl.
Screen
Some bowls have a built-in glass screen or honeycomb to stop pull-through; otherwise add a small screen.
Style
From plain workhorse slides to hand-decorated art bowls — function is the same, the look is up to you.

Bowl size and how it changes the session
Joint size gets the fit right; bowl volume decides how the piece actually smokes:
Small bowls
A shallow bowl holds roughly 0.1-0.2g - one or two hits. Best for solo sessions where the material stays fresh rather than sitting lit between pulls.
Deep bowls
0.3g+ suits rotations. The trade-off is that the lower half tends to sit partly combusted while the rotation comes back around.
Glass screens vs mesh
A built-in glass screen resists clogging and never needs replacing. Drop-in steel mesh is cheaper and easier to swap, but scorches over time.
Handle or knob
Worth more than it sounds - a bowl gets genuinely hot. A glass knob or horn lets you clear it mid-session without reaching for the rim.
When to replace a bowl
Bowls are consumables. Three signs it is time:
Airflow drops
If the hole stays restricted after an isopropyl soak, resin has hardened in the joint itself and the piece is past cleaning.
Chips at the joint
A chipped ground joint will never seal properly again - you lose suction and the bowl can drop. Replace rather than tape it.
Permanent staining
Cosmetic rather than functional, but deeply baked-in resin also holds stale flavour that carries into every bowl after it.
Frequently asked questions
How do I know if my bong takes a 14mm or 18mm bowl?
Measure the inner diameter of the joint, or compare your current bowl. 14mm is by far the most common; bigger bongs often use 18mm.
What does male and female mean for bowls?
A male bowl slides into a female joint (most bongs). If your bong's joint is the part that sticks out, it's male and you need a female bowl.
Will any 14mm bowl fit any 14mm bong?
Yes, as long as the gender matches. A 14mm male slide fits any 14mm female joint regardless of brand.
Do I need a screen in my bowl?
Only if material pulls through. Many bowls have a built-in glass screen; if yours does not, a small steel or glass screen fixes it.
Can I use an 18mm bowl on a 14mm bong?
Not directly — you'd need a 14mm-to-18mm adapter. It's easier to buy the bowl in your bong's size.
How deep should a bong bowl be?
For solo use a shallow bowl holding 0.1-0.2g keeps material fresh and avoids half-burnt leftovers. For shared sessions a 0.3g+ deep bowl means fewer reloads, at the cost of some material sitting lit between passes.
Do I need a screen in my bong bowl?
Only if material is pulling through into the water. Bowls with a built-in glass screen never need one; plain-hole bowls benefit from a steel or glass screen, particularly with finely ground herb.
How often should I clean a bowl?
Rinse in isopropyl every week or two with regular use. Resin hardens as it ages, and a bowl left un-soaked for months often cannot be fully recovered.
Can I use a 14mm bowl on an 18mm bong?
Not directly - but a 14mm-to-18mm adapter solves it. See our glass adapters if you have pieces in both sizes.
