Bong Bowls & Replacement Bowls – Sizes, Materials & Fit

Choosing the Right Bowl for Your Bong

Finding the perfect bowl isn’t complicated, it’s just about matching the right size, material, and fit.

Joint Size & Gender

Your bowl has to fit your bong’s joint. The two most common are 14mm and 18mm. If your bong has a wide female joint, you’ll need a male bowl to slide in. If it has a male joint sticking out, grab a female bowl to fit over it. Think of it like a plug and socket, it has to click.

Best Materials

Different materials give you different vibes:

Borosilicate Glass – Clean taste, durable, and lets you watch the smoke build.
Titanium or Steel – Almost unbreakable and handles heat like a champ.
Silicone – Flexible, travel-ready, and impossible to shatter.

Capacity

Pick the size that matches your session style. Small bowls are perfect for solo hits or conserving stash. Larger bowls let you pack more for sharing with friends.

Upgrade Your Session

Don’t underestimate the difference a new bowl can make. A simple glass swap can improve airflow, flavor, and the overall feel of your hits.

Which size of Bong Bowl (diameter) should I get?

It is important to choose the right diameter of bowl for your bong, and this can be determined by measuring the opening of your bong’s outer stem in millimeters. We call this measurement the joint size.

Most bongs use a 14.5mm bowl or 18.5mm bowl. The maximum size bong bowl we stock is a 29.2mm joint size. Be warned that they produce enormous rips that are only suitable for very seasoned smokers.

Use the filters in the side menu to only display joint sizes that are suitable for your bong.

When should I use a Bong Adapter?

If you have a bong that doesn’t match your bowl you can use a bong adapter.

Bong adapters provide the option to use a wrong diameter bong/bowl combination. However, you still need to make sure that the adapter you get fits both items. You can do this by measuring the pipes that connect both parts together. The bong part of the adapter should be male in most cases, whereas the bowl often needs a female part to connect to the adapter or bong.

If you are unsure about which item to get you can send us more information about your bong and bowl so we can advise you on the right adapter to buy.

Can I load concentrates into my Bong Bowl?

We would definitely advise against loading concentrates into your bong bowl as it will leave unwanted residue inside the bowl and potentially cause long term damage.

Concentrates and waxes need to melt into the bowl, meaning you need to heat up the bowl instead of its contents. This extreme heat exposure can crack the glass, as it is not designed for this type of use.

We advise you to always use a dab banger or dab nail when you want to smoke concentrates.

How do I determine my bowl’s joint size?

Use calipers or household coins-like a dime (~18 mm) or penny (~19 mm)-to measure the diameter of your bong’s joint and match it accordingly.

Which bowl material is best?

Glass offers clean taste and smooth smoke; titanium/steel bowls are stronger and endure high heat better.

Do bong bowls require screens?

Screens help prevent herb or ash from entering the downstem. You can use built-in filtration glass bowls or separate cone-style screens.

How do I clean a bong bowl effectively?

Soak in isopropyl alcohol with coarse salt, shake or scrub with a pipe cleaner, rinse thoroughly, and dry before use.
