18" Multi-Perc XL ST

18" Multi-Perc XL ST: Built for Real Sessions

You've probably tried a friend's bong and noticed the difference right away - smoother, cooler, easier on the throat.

We're always looking for pieces that offer real value without cutting corners. This one checked all our boxes.

What you're getting is proven filtration technology in a well-built piece. The water does the work of cooling and filtering your smoke, and the glass quality means you're not replacing it every few months. It's the kind of piece that pays for itself over time.

Why the Multi-Perc XL ST Stands Out

Real Filtration - Water filtration isn't just a buzzword. The Multi-Perc XL ST actually cools and filters your smoke, which means smoother draws and less throat irritation (especially on bigger hits).

Thick Glass Construction - This isn't thin, fragile glass that cracks when you look at it wrong. The thick glass walls give it a solid, sturdy feel. You can actually set this on a table without holding your breath.

Stable Base Design - The beaker shape (or straight tube, depending on your preference) means a wider base, more water capacity, and less chance of tipping over. It's functional design, not just aesthetics.

Standard 14mm Joint - Works with all standard 14mm accessories, bowls, and downstems. Our whole bowl collection is compatible, so you can customize down the road.

How Daily Smokers Uses the Multi-Perc XL ST

Daily Home Sessions: Set it up on a stable surface, fill the base with water, pack a bowl, and light up. The filtration makes a real difference on the first hit. We recommend this as a primary home piece for daily smokers.

Group Sessions: The 14mm bowl holds enough for a solid round. Pass it around the table and let the water do its thing. Bigger pieces like this are built for sharing.

Movie Night Companion: Set it on the coffee table (the stable base means no tipover anxiety), pack a bowl during the previews, and enjoy. Having it within arm's reach means less interruption.

Pro Tip: Change your water between sessions. Fresh water filters better and doesn't add that stale taste. It takes 10 seconds and makes a noticeable difference. Our team cleans the whole piece weekly with ISO + salt.

Who Should Pick Up the Multi-Perc XL ST

Home Session Regulars: If you smoke at home most of the time, a bong is the centerpiece of your setup. Better filtration, bigger hits, and a ritual that makes each session feel intentional.

Group Hosts: Having people over? A solid bong on the table says "we take this seriously." It's built for passing around and the water keeps hits smooth for everyone.

Flavor Seekers: Water filtration doesn't just cool smoke - it helps clean it. If you care about tasting your herb (not just burning it), a quality bong makes a noticeable difference.

Common Questions About the Multi-Perc XL ST

What size is the Multi-Perc XL ST?

The Multi-Perc XL ST stands 18" tall. This height provides a good balance between filtration capacity and practical daily use. Taller bongs hold more smoke volume and filter through more water, while the stable base keeps it steady on flat surfaces.

What joint size does the Multi-Perc XL ST use?

The Multi-Perc XL ST uses a 14mm joint. This is a standard size that is compatible with most flower bowls, ash catchers, and downstems on the market. Our full bowl collection works with this joint size, so you can customize your setup easily.

How do you clean the Multi-Perc XL ST?

Pour isopropyl alcohol (91% works best) and coarse salt into the bong, plug all openings, and shake vigorously for about one minute. Rinse thoroughly with warm water. For tough buildup, let the ISO and salt solution soak for 30 minutes before shaking. We recommend cleaning at least once a week.

Does the Multi-Perc XL ST come with a bowl?

Yes, every bong we ship includes a free glass flower bowl that is ready to use out of the box. The included bowl fits the 14mm joint perfectly. If you want additional bowls or different styles, check out our flower bowl collection for more options.

Is the Multi-Perc XL ST good for beginners?

The Multi-Perc XL ST works well for both beginners and experienced smokers. The water filtration makes hits smoother and easier on the throat, which is especially helpful if you are new to smoking. Start with smaller packs and work your way up as you get comfortable with the piece.

How thick is the glass on the Multi-Perc XL ST?

The Multi-Perc XL ST is made from thick borosilicate glass. This thickness provides durability for daily use and resists thermal shock from repeated heating and cooling. The glass is sturdy enough that normal handling will not cause damage, though drops can still break it.

Can you add ice to the Multi-Perc XL ST?

Yes, the ice pinch built into the neck holds ice cubes above the water line. Adding ice cools the smoke even further for extra smooth hits. Use two to three cubes for best results. Replace them as they melt to maintain consistent cooling throughout your session.

How to Clean and Maintain the Multi-Perc XL ST

Keeping your piece clean is the single best thing you can do for flavor and longevity. Here's our recommended routine:

After Each Session: Rinse with warm water to prevent resin from hardening. A quick 10-second rinse makes deep cleaning much easier later (and it only takes a moment).

Weekly Deep Clean: Fill with 91% isopropyl alcohol and coarse salt. Plug the openings and shake for 30-60 seconds. Let it soak for 15-30 minutes if there's heavy buildup. Rinse thoroughly with warm water.

Drying: Let it air dry completely before your next session. A dry piece hits cleaner and doesn't develop that stale water taste.

Warning: Never use boiling water on glass - the thermal shock can cause cracking. Warm water is fine, but keep it under 150 degrees Fahrenheit. Also avoid using abrasive cleaning tools that could scratch the interior surface of your piece.
