Water pipes & bongs
by Tsunami Glass
The Concentrate Rig Shower Head 7'' is a compact borosilicate glass dab rig built for flavour-focused concentrate sessions without the fuss. Tsunami Glass designed this one around a single showerhead percolator — enough diffusion to cool your vapour and smooth out the draw, but not so much that you lose the terpene profile you're actually paying for. At 7 inches tall, it sits comfortably on a desk, a side table, or tucked into a bag. This is a daily driver rig, not a display piece — and that's exactly why it works.
The Concentrate Rig Shower Head 7'' comes in three colourways: Green, Blue, and Amber. The colour is applied to the accent sections of the glass — the base and mouthpiece area — while the main chamber stays clear so you can watch the percolator do its thing. All three versions are identical in function and dimensions, so pick whichever one matches your setup. We'd lean towards the Amber if you're after something that hides water stains between cleanings, but honestly, they all look sharp.

Complete your dab setup with a quality butane torch and a silicone dab mat to protect your surfaces. A set of dab tools makes loading concentrates cleaner and easier, and a dedicated glass cleaning solution will keep the showerhead percolator performing at its best between sessions.

Here's the thing about big, elaborate rigs: they're brilliant for long weekend sessions, but nobody wants to fill, heat, and clean a 14-inch recycler on a Tuesday evening after work. You want something you can grab, heat up, take a dab, and set back down. The Concentrate Rig Shower Head 7'' from Tsunami Glass is exactly that — a no-nonsense piece that does one job and does it well.
The showerhead percolator sits at the base of the chamber and splits your vapour through multiple small slits as it passes through the water. That gives you enough cooling and filtration to take the harshness off, but the short vapour path means terpenes and flavour compounds actually reach your palate instead of condensing on glass walls halfway up a massive tube. If flavour matters to you — and if you're dabbing concentrates, it should — a compact rig like this outperforms bigger pieces almost every time.
The borosilicate glass is the same stuff used in lab equipment. It handles rapid temperature changes without cracking, which matters when you're torching a banger directly attached to the piece. At 7 inches, the rig is sturdy enough to sit on a table without tipping, but light enough to hold comfortably in one hand. The one honest limitation: because it's compact, the water chamber is small. You'll want to change the water frequently — every session or two — to keep the flavour clean. That's a 30-second job, though, so it's hardly a dealbreaker.
Compared to something like a larger recycler rig, you're trading water volume and visual drama for portability and flavour purity. We'd pick this Tsunami Glass piece over a bigger rig for solo sessions nine times out of ten. If you're hosting friends and want something more theatrical, size up. For everything else, this is the one.
We've handled a lot of Tsunami Glass pieces over the years, and the build quality on their smaller rigs is consistently solid. The glass walls on the Shower Head 7'' feel thick enough to survive a bump against a table edge — though obviously, don't test that theory on purpose. The joint connection is well-ground and airtight, which isn't always the case with budget rigs. One thing worth mentioning: the mouthpiece opening is on the narrower side. That's actually a plus for concentrates — it directs vapour more efficiently — but if you're used to wide-mouth bongs, it'll feel different at first.
The showerhead perc produces a satisfying, quiet bubble. It's not the aggressive chug of a tree perc or the whisper of a honeycomb — it's somewhere in between. Smooth draw resistance, minimal drag. You can clear the chamber in one comfortable pull without feeling like you're fighting the piece. For a 7-inch rig at this price point, that's exactly what you want.
The showerhead perc is a disc with multiple slits cut into its underside. When you inhale, vapour is forced through these slits and broken into smaller bubbles, increasing the surface area that contacts the water. More contact means better cooling and filtration. It's one of the most reliable perc designs — effective, easy to clean, and hard to clog.
Technically, you could swap the banger for a 14mm dry herb bowl, but we wouldn't recommend it as your primary flower piece. The small chamber and short vapour path are optimised for concentrates. Dry herb smoke is harsher and benefits from more water volume and filtration. You'd get a better experience from a dedicated bong for flower.
Borosilicate glass contains boron trioxide, which makes it resistant to thermal shock — meaning it won't crack when exposed to rapid temperature changes from torching a banger. It's the same type of glass used in laboratory beakers and high-end cookware. Compared to regular soda-lime glass, it's significantly more durable and heat-resistant.
Every session, ideally. Concentrate vapour leaves oily residue in the water that builds up fast and starts to affect flavour. Fresh water takes 10 seconds to swap and makes a noticeable difference in taste. If you're doing multiple dabs in one sitting, changing water between every 3–4 dabs keeps things tasting clean.
Not at all — for concentrates, smaller is often better. A shorter vapour path means less surface area for terpenes to condense on before reaching you, which translates to more flavour per hit. Most dedicated dabbers prefer rigs in the 6–9 inch range. Bigger rigs work, but you lose some of the subtlety that makes concentrates worth the effort.
The rig uses a 14mm female joint, so you'll need a 14mm male banger or nail. This is the most common joint size for concentrate rigs, so finding replacement bangers or upgrading to a terp slurper or spinner cap setup is straightforward.
Fill the rig with isopropyl alcohol (90% or higher) and add a tablespoon of coarse salt. Cover the openings, shake gently for 30–60 seconds, and let it soak for 15–20 minutes if the buildup is stubborn. Rinse thoroughly with warm water afterwards. The showerhead design is one of the easier percs to clean because the slits are relatively large and accessible.
