Water pipes & bongs
The Glass Bong Double Bowl is a borosilicate water pipe with twin orb chambers that fill with dense, milky smoke as you draw. The double-bowl design filters your hit through two separate water reservoirs before it reaches the angled mouthpiece, giving you visibly cooler and smoother pulls than a single-chamber piece. If you like watching your smoke travel — and honestly, who doesn't — this one puts on a proper show.
Most bongs at this price point give you a single straight tube and call it a day. The Double Bowl earns its name with two stacked glass orbs that fill sequentially — bottom first, then top — creating that snowman silhouette as cannabinoid-rich vapour passes through. It's a genuinely satisfying visual, and it never gets old. We've had this piece on the shop floor for a while now, and people still stop to watch it fill up.
The angled mouthpiece is the other detail worth mentioning. Instead of craning your neck over a vertical tube, you tilt the bong slightly and the mouthpiece meets you at a comfortable angle. Sounds minor, but after a few sessions you notice the difference — especially if you're passing it round with mates and don't want to explain the ergonomics of neck strain every time.
The carb hole on the side gives you direct control over airflow. Cover it while you draw to build up thick smoke in both orbs, then release to clear the chambers in one rush. According to research from Examine.com, vaporisation and water filtration may reduce the amount of combustion byproducts inhaled compared to unfiltered methods, though more research is needed on the precise filtration efficiency of water pipes (Examine, 2024).
We'll be straight with you — this is a lightweight glass piece. It's not a 5mm-thick scientific beaker that you can knock against the table without worry. The glass is thinner than something like the Blaze Glass Ice Bong, so treat it with a bit of respect. Keep it on a stable surface, don't leave it teetering on a sofa arm, and it'll last you ages. The upside of that lighter build is that it's easy to handle with one hand, and the compact size means it doesn't dominate your coffee table.
The taste through this piece is clean — no metallic tang, no plastic aftertaste, just glass and water doing what they do best. You get the full terpene profile of whatever you pack into the bowl, which is the main reason glass remains the go-to material for bongs. If you've been smoking through an aluminium pipe or a plastic bottle (no judgement, we've all been there), the difference in flavour clarity is immediate.

Complete your setup with a proper grinder — the SLX Non-Stick Grinder gives you a consistent, fluffy grind that packs evenly into the bowl. A set of pipe screens keeps debris out of the water, and a bottle of Formula 420 cleaner will keep both orbs crystal clear between sessions.
Rolling a joint is ritual, sure. But a bong gives you something papers can't: water filtration. Each hit passes through water before reaching your lungs, which cools the smoke down noticeably. According to a quantification study published in PMC, water pipe use allows for more controlled dosing per session compared to joints, where burn rate and sidestream loss make it harder to gauge intake precisely (PMC, PMC3025094). That matters if you're trying to be mindful about how much you consume.
There's a practical angle too. A bong bowl holds roughly 0.1–0.3g per pack depending on how tight you load it. A standard joint uses 0.3–0.5g or more, and a good chunk of that burns off between puffs. With a bong, nothing burns until you put flame to it and draw. Less waste, more control, better flavour.
The double-chamber design on this particular piece adds a second pass through water. That extra filtration step means the smoke reaching your mouth is noticeably cooler than what you'd get from a single-chamber bong of the same size. If you find single-chamber hits a bit harsh, this is a solid step up without jumping to a full percolator setup.
Glass bongs look brilliant when they're clean and absolutely grim when they're not. The double-orb design on this piece means residue can build up in the curved sections between chambers if you leave it too long. Our advice: rinse with hot water after every session, and do a proper clean with isopropyl alcohol and coarse salt once a week if you're a daily user.
Pour the alcohol and salt into the bong through the mouthpiece, cover both openings with your palms, and shake vigorously for 60–90 seconds. The salt acts as an abrasive against the resin, and the alcohol dissolves the sticky residue. Rinse thoroughly with warm water afterwards — you don't want alcohol fumes in your next hit. A clean bong means cleaner flavour, and with glass this transparent, you can see exactly when it needs attention.
| Cleaning frequency | Method | Time needed |
|---|---|---|
| After every session | Empty water, rinse with hot water | 30 seconds |
| Weekly (daily users) | Isopropyl alcohol + coarse salt shake | 2–3 minutes |
| Monthly (occasional users) | Soak in Formula 420 or similar cleaner | 15–30 minutes |
It creates two separate filtration stages. Smoke passes through water in the lower orb first, then again in the upper orb before reaching the mouthpiece. The result is a noticeably cooler, smoother hit compared to a single-chamber bong of similar size.
It's borosilicate glass, which handles heat well, but the walls are on the thinner side. It won't shatter from normal use or temperature changes. Just don't drop it on a hard floor or clank it against the tap when rinsing. Treat it like a wine glass and you'll be fine.
Fill until the water sits about 1 inch (2.5 cm) above the internal openings in each orb. You can test by drawing air through the mouthpiece without lighting anything — if you hear bubbling in both chambers without getting water on your lips, you've nailed it.
The orb openings on this piece are too narrow for ice cubes. You can use cold water instead, which achieves a similar cooling effect. Some people add a few drops of lemon juice to the water to help prevent resin buildup — it works, and it smells better than stale bong water.
Every single session. Stale bong water breeds bacteria within 24 hours and ruins the taste of your herb. Fresh water takes 10 seconds to swap out and makes a massive difference to flavour and hygiene.
The carb hole lets you control airflow. Cover it while drawing to build up thick smoke in both orbs, then release it to clear the chambers in one clean pull. It gives you more control over hit size than a bong with a removable downstem.
For flavour, yes — glass is inert and adds nothing to the taste of your smoke. Silicone bongs are practically indestructible, which makes them better for travel or clumsy moments. If flavour is your priority and the bong stays on a shelf at home, glass wins every time.
