Water pipes & bongs
by Groove
The Groove 7 Small Rig Bubbler is a compact 18 cm (7-inch) borosilicate glass dab rig that ships with both a 14 mm bowl and a 90-degree banger for immediate dual-use out of the box. Built by Groove — a brand that's earned a solid reputation for clean glass design and reliable ground glass fittings — this compact rig punches well above its size. Whether you want to buy a dedicated dab rig or need a versatile piece for concentrates and dry herb, the Groove 7 Small Rig Bubbler delivers concentrated, full-flavoured hits from a footprint that barely takes up shelf space.
The Groove 7 Small Rig Bubbler stands out because its 18 cm vapour path hits the exact sweet spot between cooling and flavour retention. Too short and you get harsh, hot hits. Too convoluted and you lose flavour in all the wrong places. At 18 cm, there's enough distance between the banger and your lips to cool the vapour noticeably, but the path is short enough that terpene-rich flavour doesn't get lost swirling through excess water and glass. You taste what you're dabbing, not just hot air.
Pick it up and you'll notice the weight first. This isn't some paper-thin import that feels like it'll crack if you set it down too firmly. The glass walls have genuine thickness to them, and the base sits flat and stable on a desk or table. The black accents on clear glass give it a look that's understated rather than flashy — the kind of piece you leave out without it screaming "dab rig" to every visitor.
The ground glass connections deserve a mention because they're often where cheaper rigs cut corners. On the Groove 7, the 14 mm joint is properly frosted and sits flush. No wobble, no air leaks, no having to hold the bowl in place while you light up. It's a small detail, but after you've used a rig with a sloppy joint, you never want to go back.
The Groove 7 Small Rig Bubbler measures 18 cm tall, features a 14 mm ground glass joint at 90 degrees, and is made from clear borosilicate glass with black accent highlights.

The Groove 7 Small Rig Bubbler ships with everything you need to start dabbing or smoking dry herb immediately — no extra purchases required on day one.
That dual-use setup is genuinely useful. Most rigs at this size ship with one or the other, and you end up spending extra on the missing piece. Groove includes both, which means you can switch between concentrates and dry herb just by swapping the attachment. Takes about 3 seconds.
Concentrates don't need a massive chamber to filter and cool — a compact rig preserves more terpene flavour by keeping the vapour path short and direct. We've sold big beaker bongs for over two decades, and they have their place — nobody's arguing that. But here's what we've seen behind the counter: people who dab regularly almost always end up downsizing their rig. All that extra glass and water can actually strip flavour from your dabs. You paid good money for those terpy extracts — why lose half the taste to a 45 cm bong designed for flower?
From our counter: one of our Amsterdam shop regulars switched from a 35 cm recycler to the Groove 7 Small Rig Bubbler and told us the flavour difference on live rosin was "night and day." He'd been blaming his extracts for muted taste when the real culprit was an oversized rig drowning the terpenes. Less surface area means less condensation, less flavour loss, and more of those terpene profiles hitting your palate the way the extract maker intended. The 18 cm height still gives you enough water filtration to smooth out the hit, but it doesn't drown the flavour.
There's a practical side too. A 7-inch rig fits in a drawer, sits on a bedside table, travels in a padded bag without drama. Try doing that with a 40 cm beaker. The Groove 7 is the kind of piece you reach for daily precisely because it's always within arm's reach. If you're ready to order a compact rig that doesn't compromise on build quality, this is a strong starting point.
The honest limitation? If you're someone who takes absolutely massive dabs — we're talking 0.3 g globs — this rig's chamber will feel small. For standard-sized dabs (0.05–0.15 g, where most people live), it's spot on. If you regularly go bigger, look at something in the 25–30 cm range instead.
Using the Groove 7 Small Rig Bubbler takes about 60 seconds from filling to first hit — here's the step-by-step process for both concentrates and dry herb.
The Groove 7 Small Rig Bubbler beats larger rigs on flavour retention and portability but trades off chamber size for heavy sessions — here's a direct comparison.
| Feature | Groove 7 (18 cm) | Typical 25-30 cm Rig |
|---|---|---|
| Height | 18 cm / 7 inches | 25–30 cm / 10–12 inches |
| Flavour retention | Excellent — short vapour path | Good — more surface area dilutes flavour |
| Hit smoothness | Smooth for standard dabs | Smoother for large dabs |
| Portability | Fits in a drawer or small bag | Needs dedicated shelf space |
| Best for | Daily dabbing, flavour chasers | Heavy sessions, group use |
| Bowl and banger included | Yes — both | Varies by brand |
Complete your dab setup with a reliable butane torch for heating the banger, a set of stainless steel dab tools for handling concentrates cleanly, and a silicone dab mat to protect your table from heat and sticky residue. If you're using the Groove 7 Small Rig Bubbler for dry herb as well, get a decent grinder — it makes a real difference to airflow and burn consistency. We'd point you towards a 4-piece aluminium grinder with a kief catcher. You can buy all of these accessories separately in our smoking accessories category.
Yes. It ships with both a 14 mm glass bowl for dry herb and a 90-degree banger for concentrates. Swap between them in seconds — no adapters needed.
Enough to submerge the downstem by roughly 1–2 cm. Test by drawing air through the mouthpiece without heating. If water touches your lips, pour some out. Overfilling kills the hit.
Not at all — for concentrates, smaller rigs actually preserve more flavour because the vapour travels a shorter distance. The Groove 7 Small Rig Bubbler's 18 cm height is a sweet spot for daily dabbing with standard-sized dabs (0.05–0.15 g).
Any 14 mm male accessory fits the Groove 7's ground glass joint. The included banger is a 90-degree angle, so replacement bangers should match that angle for a proper fit.
Rinse with warm water after every session. For a deeper clean, fill the chamber with isopropyl alcohol (90%+) and coarse salt, shake vigorously, then rinse thoroughly with warm water. Do this weekly if you use it daily — the clear glass shows residue quickly, so you'll know when it's time.
No. It includes a bowl and banger but no carb cap. A universal carb cap that fits over the banger opening will improve low-temp dabs significantly — worth adding to your order.
The glass walls are noticeably thick for a rig this size, and the low centre of gravity helps it stay stable on flat surfaces. It's not indestructible — it's glass — but it feels sturdier in hand than most compact rigs we've handled.
