2″ 18MM DIAMOND SHAPE FLOWER BOWL

The 2" 18mm Diamond Shape Flower Bowl is a glass replacement bowl built for smokers running 18mm setups who want something that actually looks as good as it rips. At about 2 inches (50.8mm) long with a thick diamond-cut body, it gives you a comfy grip and a nice visual pop every time you clear it. If your favorite piece has an 18mm female joint and you’re ready to ditch the boring stock bowl, this is that simple upgrade that makes the whole rig feel new again.

What You Get

• Instant upgrade for 18mm bongs — Drops right into any standard 18mm female joint so you can swap out that chipped or basic bowl in seconds.
• Better grip, less fumbles — The diamond shape and thick horn give you something solid to hold, so you’re not pinching a tiny tab with hot glass nearby.
• Cooler pulls, less stress — Thick glass walls help handle heat so the bowl doesn’t get scorching as fast during back-to-back packs.
• Integrated glass screen — Built-in diffusion means fewer crumbs dropping into your piece and a smoother hit without hunting for a metal screen.
• Colors that match your setup — Multiple color options let you coordinate with your favorite tube, ash catcher, or whatever else is on the shelf.
• Simple clean, fresh flavor — Smooth glass interior wipes down easily, so you can keep it tasting like your flower instead of last week’s leftovers.

Best For

This bowl is made for people who actually use their glass and want a reliable daily driver piece that doesn’t look generic. It’s ideal if you’re running a taller beaker or straight tube with an 18mm female joint and you want a bowl that’s easy to grab when you’re a few bowls in and just want things to work. If you’re already curating a little lineup of pipes and bowls, it fits right in with the rest of your smoke shop gear without looking like an afterthought.

How to Use It

Pop your old bowl out, slide this 18mm diamond bowl into your female joint, and you’re basically set. Pack your ground flower into the bowl (don’t overpack so air can still move through), and you’re ready for the next sesh. The horned handle makes it easy to pull and clear without getting your fingers too close to the hot end, especially on heavier pulls.

Between rips, tap out the ash gently instead of banging it on something hard — that diamond-cut glass looks better when you don’t chip it. If you like to keep your station tidy, parking your bowl on a dab mat between uses keeps ash and resin off the table.

For cleaning, let the glass cool, then wipe or rinse out loose ash. For deeper cleans, soak in isopropyl alcohol, rinse thoroughly with warm water, and let it dry before you pack it again. If you rotate bowls, you can keep this one soaking while you run a backup from your stash of accessories.

Specs

Fit & Compatibility

This bowl is designed specifically for 18mm female joints. If your water pipe, bong, or rig takes an 18mm male downstem or slide, this will drop right in and seal properly. It won’t fit 14mm or 10mm joints, so if your current bowl feels noticeably smaller or larger, double-check the size before you upgrade. For people who like to keep different bowls for different strains, pairing this with a couple of spare pieces and some labeled glass jars makes swapping flavors way easier.

FAQ

• Will this fit my bong?
  If your piece has an 18mm female joint, this 18mm male flower bowl will fit. If you’re unsure, compare the opening to a known 18mm downstem or check your original bowl’s size before buying.
• Can I use this with smaller joints like 14mm?
  Not by itself. This bowl is sized for 18mm joints only. If you’re running a 14mm piece, you’d need an adapter, or you can just stick to 14mm hardware and keep this one for your bigger setups or future glass. If you’re building a mixed kit with rigs, bowls, and more, browse our silicone bongs & rigs for pieces that match your preferred joint size.
• Does the integrated glass screen mean I don’t need metal screens?
  Most people won’t need an extra metal screen with this bowl. The built-in glass screen helps keep small bits of flower from dropping through while still letting air flow. If you like ultra-fine grinds or pack very loose, you can still add a screen, but it’s optional.
• How do I keep the diamond bowl looking clear?
  Let it cool after your sesh, knock out the ash gently, and give it a quick rinse when you notice buildup. For deeper cleans, soak in isopropyl alcohol, rinse thoroughly, and dry before use. Keeping your flower in clean, sealed storage packaging also helps cut down on sticky residue and keeps flavor on point.
• Is the glass thick enough for daily use?
  The bowl is made from durable glass with a thicker profile, especially around the diamond section and horn, so it’s built for regular use. That said, it’s still glass — try not to slam it against the sink or table. Treat it like your other favorite pieces and it’ll hold up as a solid daily driver.
• Can I use this bowl on a rig I normally dab with?
  As long as your rig has an 18mm female joint, this flower bowl will work just fine. Many people swap between a banger and a flower bowl on the same piece. Just remember to switch back to your banger or dab tools when you’re going back to concentrates so flavors don’t collide.
• What’s the advantage of the diamond shape over a regular round bowl?
  The diamond shaping isn’t just for looks — it gives you more surface area and a more comfortable grip point while also adding a bit of thickness where bowls usually crack or chip. Plus, on the shelf or in a lineup of bowls, that diamond cut just stands out instead of blending in like another plain slide.
