Water pipes & bongs

We'll only email you about this product — no marketing.
The Freezable Upright Bubbler is a 12-inch glycerin-cooled water pipe that chills smoke through frozen Kryogel and a showerhead percolator before it reaches your lips. Made by Kryo, this bubbler strips the harshness out of every hit without sacrificing flavour — freeze it, fill it, light it, done. Available in Black and White, it breaks down for easy cleaning and travels surprisingly well for its size.
Both variants are identical in function — same Kryogel chamber, same showerhead percolator, same 12-inch build. The only difference is the colourway. Black (HS2336) hides resin buildup between cleans a bit better. White (HS2335) looks sharper out of the box and shows water level more clearly. Pick whichever suits your setup.
Here are the numbers that matter when you're deciding whether this freezable upright bubbler fits your routine.

Complete your setup with a decent grinder and a set of pipe cleaners. A solid 4-piece herb grinder gives you an even, consistent bowl every time — which matters more than you'd think when you're pulling through water filtration. Isopropyl alcohol and coarse salt are your best friends for keeping the Kryogel chamber and percolator free of buildup.
Standard dry pipes deliver smoke at whatever temperature combustion produces. That means hot, harsh hits that scratch the back of your throat and make you cough before you've even finished inhaling. Water pipes help — they cool and filter — but a regular bubbler at room temperature only does half the job.
The Kryo Freezable Upright Bubbler stacks two cooling systems on top of each other. First, the all-natural Kryogel. You stick the bubbler in the freezer for a couple of hours, and the gel locks in cold without the mess of ice cubes or the risk of meltwater flooding your chamber. The gel stays frozen long enough for a proper session — we've found it holds cold for roughly 30 to 45 minutes of active use depending on room temperature. Second, the showerhead percolator breaks your smoke into dozens of tiny streams as it passes through water, massively increasing the surface area that gets cooled and filtered. The combination means smoke hits your lungs noticeably cooler and smoother than a standard bubbler or even a mid-range bong without glycerin cooling.
At 12 inches, it sits in a sweet spot. Tall enough to house a proper percolator and Kryogel chamber, short enough to slide into a bag. We've seen customers treat this as their daily driver at home and their travel piece for weekends away — it does both jobs without complaint. The one honest limitation: glass and glycerin add weight, so it's not featherlight. Handle it with care, especially when frozen, because cold glass is slightly more brittle than room-temperature glass. A padded case is worth the investment if you're moving it around regularly.
The freezable upright bubbler takes about 2 minutes to set up once you've frozen the Kryogel. Here's the full process from freezer to first hit.
The showerhead percolator in this freezable bubbler works by forcing smoke through small slits submerged in water. If the water level is too low, smoke bypasses the slits entirely and you lose most of the filtration benefit. If it's too high, water travels up the neck and into your mouth — unpleasant, to say the least.
The sweet spot is about 1 cm above the percolator slits. After filling, do a dry pull (inhale without lighting) to test. You should hear a steady bubbling sound without any water reaching your lips. Adjust from there. Cold water works fine, but since the Kryogel is already doing the heavy cooling, room-temperature water is perfectly adequate. Changing the water after every session keeps flavour clean and prevents resin building up inside the percolator — which is the single most common maintenance issue we see with showerhead percs.
Kryo designed this freezable upright bubbler to come apart completely, which makes cleaning straightforward rather than a chore. Here's what we'd recommend based on years of handling water pipes behind the counter.
After each session, empty the water and give every component a rinse under warm running water. Once a week — or more often if you're a daily user — do a proper soak. Disassemble everything, drop the glass components into a zip-lock bag with isopropyl alcohol (90% or higher) and a tablespoon of coarse salt. Shake gently for 2 to 3 minutes. The salt acts as an abrasive, the alcohol dissolves resin. Rinse thoroughly with warm water afterwards. Never put the Kryogel section in boiling water or a dishwasher — extreme heat can damage the gel. Warm water and alcohol are all you need.
The showerhead percolator has small slits that can clog over time. If you notice reduced bubbling or harder draws, that's your sign to clean. A thin pipe cleaner threaded through each slit clears buildup fast. Keeping on top of this means your freezable bubbler performs like new for months.
A standard bubbler gives you water filtration in a compact package — solid choice, but the smoke is still warm. A full-size bong with an ice catcher adds cooling, but ice melts fast and raises the water level as it does, changing your hit quality mid-session. The Kryo Freezable Upright Bubbler sits between the two: more cooling than a regular bubbler, more portable than a bong, and the Kryogel doesn't melt into water.
| Feature | Standard bubbler | Bong with ice catcher | Kryo Freezable Upright Bubbler |
|---|---|---|---|
| Height | 6–8 inches | 14–18 inches | 12 inches |
| Cooling method | Water only | Water + ice cubes | Water + Kryogel + showerhead perc |
| Meltwater issue | None | Yes — raises water level | None — gel stays contained |
| Portability | High | Low | Medium-high |
| Disassembly for cleaning | Rarely | Sometimes | Fully disassemblable |
| Percolator | Usually none | Varies | Showerhead |
If you already own a decent bong and want something for travel or a second-room setup, the Kryo is the best freezable bubbler for portable use without sacrificing cooling performance. If you've never used a water pipe before, this is honestly a great starting point — the dual cooling system is forgiving and the learning curve is basically zero.
Roughly 30 to 45 minutes of active use at room temperature. In a cooler environment it lasts longer. Pop it back in the freezer between sessions and it's ready again in 1 to 2 hours.
Kryogel is an all-natural, non-toxic glycerin-based gel sealed inside the glass chamber. It never contacts your smoke or water directly — it cools through the glass wall. Completely food-safe and designed specifically for freezable smoking devices.
Yes. The showerhead percolator and water filtration work regardless. You just won't get the extra cooling from the Kryogel. It functions as a solid standard bubbler even at room temperature.
Enough to cover the showerhead percolator slits by about 1 cm. Do a test draw without lighting to check — steady bubbling with no water reaching your lips means you've nailed it.
No. The heat from a dishwasher cycle can damage the Kryogel. Stick to warm water and isopropyl alcohol for cleaning. Hand-wash only, always.
Slightly more resistance than a dry pipe, but nothing uncomfortable. The slits are designed for a smooth, steady pull. If the draw feels tight, the percolator slits likely need a clean.
Purely cosmetic. Same Kryogel, same showerhead percolator, same 12-inch build. Black hides resin slightly better between cleans; White shows water level more clearly. Pick whichever you prefer.
