Water pipes & bongs
by Tsunami Glass
The Dab Rig Shower Head 8" from Tsunami Glass is a compact borosilicate glass water pipe built around a showerhead percolator that filters and cools vapour with surprising efficiency for its size. At just 8 inches tall, it sits low on your desk or coffee table, takes up barely any shelf space, and still delivers the kind of smooth, full-flavoured hits you'd expect from something twice its height. If you've been hunting for a daily driver dab rig that doesn't demand a dedicated corner of the room, this is the one we'd point you towards.
Tsunami Glass has built a solid reputation for functional glass at sensible prices, and the Shower Head rig is a good example of why. No over-engineered percolator stacks, no fragile recycler arms — just a single showerhead perc doing exactly what it needs to do. The design keeps drag low, so you're not fighting the piece for airflow, and the water chamber stays compact enough that flavour doesn't get lost in transit. We've pulled concentrates and dry herb through this rig, and both come through clean.
The Shower Head Dab Rig ships in four colourways. All four share identical dimensions, glass thickness, and percolator design — the only difference is the accent colour on the mouthpiece and base. Pick whichever catches your eye; there's no functional difference between them.

Complete your dab setup with a proper quartz banger if you don't already own one — quartz retains heat more evenly than glass nails and won't crack under repeated torching. A dab tool and silicone mat are worth grabbing too, especially if you're working with sticky concentrates. Pair this rig with a decent butane torch and you're sorted from day one.
Here's the thing about large rigs: they look impressive, they hit well, but they're a pain to clean, awkward to store, and nerve-wracking to move around. The 8-inch Shower Head rig from Tsunami Glass sidesteps all of that. It's small enough to hold comfortably in one hand, light enough that you won't white-knuckle it every time you pass it, and short enough to tuck behind a monitor when company arrives.
But compact doesn't mean weak. The showerhead percolator inside this rig pulls vapour through multiple slits in a disc-shaped diffuser, breaking it into dozens of tiny bubbles. More bubbles means more surface area contacting the water, which means more heat gets stripped out before the vapour reaches your lungs. The result is a noticeably cooler, smoother draw — even on big dabs. We've run concentrates through this at fairly aggressive temperatures and the hit still came through clean without that throat-scorching harshness you get from unfiltered rigs.
The honest limitation? An 8-inch rig holds less water than a full-size piece, so you'll want to change it more frequently. Stale water in a small chamber gets funky faster than in a 14-inch beaker. Swap it out every session or two and you'll keep the flavour pristine. That's a minor trade-off for the portability and ease of cleaning — a quick rinse with isopropyl alcohol and coarse salt and this thing looks brand new in under 2 minutes.
A showerhead percolator is one of the simplest and most reliable filtration systems in glass. It sits inside the water chamber as a disc or tube with multiple small slits cut around its circumference. When you inhale, smoke or vapour is forced down through these slits and into the water, creating a cluster of fine bubbles. Each bubble acts as a tiny cooling unit — heat transfers from the vapour into the surrounding water across the bubble's surface. The more slits, the more bubbles, the cooler and smoother the draw.
Compared to tree percolators (which have fragile arms that snap) or honeycomb percs (which clog if you don't clean religiously), showerhead percs hit a sweet spot between filtration quality and durability. There are no delicate protruding parts to break, and the open slit design resists clogging better than pinhole-style diffusers. For a daily-use rig, that reliability matters more than having 6 stacked percolators that look impressive on a shelf but turn into a cleaning nightmare.
We've been stocking Tsunami Glass pieces for a while now, and the Shower Head rig is one of those products that quietly outsells flashier options. Customers who come back tend to say the same thing: they expected it to be a backup piece and it ended up replacing their main rig. The compact size makes it less intimidating for people new to concentrates, and the showerhead perc keeps things forgiving even if your technique isn't dialled in yet.
One thing worth mentioning: this rig works well for dry herb too if you swap the banger for a standard glass bowl. It's not exclusively a dab rig, despite the name. That dual functionality is genuinely useful if you switch between concentrates and flower depending on the day. Compared to a straight-tube bong of similar height, the showerhead perc gives you meaningfully smoother hits — you'll feel the difference on the first pull.
If you're weighing this against a recycler rig, here's our take: recyclers look brilliant and recirculate water for extra cooling, but they're harder to clean and more expensive. The Shower Head rig won't give you the same visual theatre of water looping through chambers, but it matches the smoothness for most people and costs less. For a first dab rig or a no-fuss daily piece, we'd pick this over a recycler nine times out of ten.
A dab rig is a water pipe designed specifically for vaporising concentrates like wax, shatter, or rosin. The main difference from a bong is the joint type and attachment — dab rigs use a banger or nail heated with a torch, while bongs use a bowl packed with dry herb. Dab rigs also tend to be smaller to preserve vapour flavour over shorter airpaths.
Yes. Swap the banger for a compatible glass bowl and it functions as a standard water pipe for dry herb. The showerhead percolator filters smoke just as effectively as it filters vapour, so you get smooth hits either way.
Every session, or every two sessions at most. Smaller rigs hold less water, so it gets discoloured and stale faster than in larger pieces. Fresh water means better flavour and cleaner filtration from the showerhead percolator.
A-grade borosilicate glass — the kind Tsunami Glass uses here — is the same material used in laboratory glassware. It handles thermal shock from torch heating without cracking and resists everyday knocks better than soft glass. It's not indestructible, but it's the best glass type for a rig you'll use regularly.
The rig uses a standard female joint. Check the joint size (typically 14mm for rigs of this size) and grab a male quartz banger to match. If you're unsure, a 14mm male banger is the safest bet for most 8-inch Tsunami Glass rigs.
Showerhead percs balance filtration, durability, and ease of cleaning better than most alternatives. They have no fragile arms like tree percs, don't clog as fast as honeycomb percs, and produce enough diffusion for smooth hits without adding excessive drag. For a compact daily rig, they're hard to beat.
Pour 90%+ isopropyl alcohol and coarse salt into the rig, cover the mouthpiece and joint openings, and shake vigorously for 30–60 seconds. The salt acts as an abrasive to scrub residue off the perc slits. Rinse with warm water until the alcohol smell is gone. Do this weekly for best results.
