Water pipes & bongs

The Shower Head Dab Rig 11" is a borosilicate glass concentrate rig that filters vapour through a shower head percolator for noticeably cooler, smoother draws. Built by Tsunami Glass with a thick base, bent neck, and rimmed mouthpiece, it sits at 11 inches tall — big enough to deliver serious diffusion, compact enough to keep on your desk without it looking like lab equipment. If you've been dabbing off a basic rig and wondering why the flavour always tastes a bit scorched, this is likely the upgrade that fixes it.
This rig ships in two variants — Amber (HS2155) and Green (HS2154). Both are identical in specs and performance. The colour is in the glass accent, not a coating, so it won't peel or fade over time. Go with whichever matches your setup, or whichever one your housemate won't accidentally claim as theirs.
A shower head percolator sits inside the base chamber and works like this: vapour is pulled down through a central tube and forced out through a disc covered in small slits. Those slits break the vapour into dozens of tiny bubbles, massively increasing the surface area that contacts the water. More contact means more cooling and more filtration before anything reaches your lungs. The result is a draw that tastes cleaner and feels far less harsh on the throat.
We've handled a lot of rigs behind the counter over the years, and the shower head design consistently delivers the best balance between flavour preservation and smooth hits. Tree percs and honeycomb percs work well too, but they tend to create more drag — you pull harder, which can strip some of the terpene flavour from low-temp dabs. The shower head keeps airflow relatively open while still breaking up the vapour properly. For concentrates specifically, that matters more than it does for dry herb.
The honest limitation? This is a single-perc rig. If you're chasing maximum filtration and don't mind a bit more drag, a double-perc or recycler rig will cool things down even further. But for most people dabbing at sensible temperatures, one shower head perc is the sweet spot — you get the cooling without losing flavour to over-filtration. That's the trade-off, and Tsunami Glass has landed on the right side of it here.
Tsunami Glass built this rig from borosilicate glass — the same type used in laboratory glassware because it handles thermal shock without cracking. The base is extra-thick, which matters more than you'd think. A top-heavy rig with a thin base is a broken rig within the first month. This one sits flat and stable, and you can feel the weight when you pick it up. It's solid without being clumsy.
The bent neck isn't just for looks. It angles the mouthpiece away from the heat source, so you're not hovering your face directly over a hot banger. The rimmed mouthpiece creates a comfortable seal against your lips — no sharp edges, no awkward flat rim that you have to press into. Small detail, but after a few sessions you notice it.

Complete your dab setup: A rig is only half the equation. Pair this with a proper quartz banger for clean, low-temp dabs that let the shower head percolator do its job. A dab tool and silicone mat keep things tidy between sessions — concentrates and bare tabletops are not friends.
Here's what we see constantly: someone buys a nice concentrate, heats up a makeshift setup or a tiny nectar collector, and wonders why the flavour is harsh and the hit feels like it scraped the back of their throat. The problem isn't the concentrate — it's the lack of water filtration and the wrong form factor.
A dedicated dab rig with a percolator changes the experience completely. The water cools the vapour from around 200-300°C down to something your throat can actually handle. The shower head perc in this Tsunami rig breaks that vapour into small bubbles across multiple slits, so by the time it reaches the mouthpiece, it's smooth and the flavour profile of your concentrate comes through properly. You taste the terpenes instead of just the heat.
The 11-inch height is also a deliberate choice. Smaller rigs (6-8 inches) are portable but don't give vapour enough travel distance to cool properly. Taller rigs (14+ inches) cool beautifully but create so much drag that you lose vapour density. At 11 inches, this Tsunami rig sits right in the middle — enough chamber volume for real cooling, enough airflow to keep your draws satisfying. We'd call it the best size for a daily-use dab rig that stays on your desk or shelf.
It forces vapour through a disc with multiple slits, splitting it into many small bubbles. This increases the surface area contacting the water, which cools and filters the vapour before it reaches your mouth. The result is a smoother, more flavourful draw compared to a rig with no percolation.
Yes — it's one of the best perc types for concentrate flavour. It provides enough diffusion to cool the vapour without over-filtering it the way stacked percolators can. You get smooth hits that still carry the full terpene profile of your concentrate.
Technically you could fit a dry herb bowl onto the joint, but this rig is designed and optimised for concentrates. The chamber volume and perc style are tuned for vapour, not smoke. For dry herb, you're better off with a dedicated bong or a larger water pipe with a different perc setup.
Every session, ideally. Stale water tastes awful and defeats the purpose of having a percolator. Fresh water takes 10 seconds to swap and makes a noticeable difference in flavour. If you're doing multiple dabs in one sitting, at least change it daily.
Borosilicate is the same glass used in lab beakers — it handles heat cycling without cracking and is more impact-resistant than regular soda-lime glass. The extra-thick base on this Tsunami rig adds stability. That said, it's still glass. Don't knock it off the table and you'll be fine for years.
Check the joint size on the product listing — Tsunami Glass typically uses standard 14mm female joints on their 11-inch rigs. A 14mm male quartz banger is the most common pairing. If you're unsure, drop us a message before ordering.
Fill the rig with isopropyl alcohol (90% or higher) and add a tablespoon of coarse salt. Cover the openings, shake gently for a minute, and let it soak for 30 minutes. Rinse thoroughly with warm water. The shower head slits can trap residue, so a weekly clean keeps airflow and flavour at their best.
