Thinking about buying a glass bong but not sure where to start? The questions we hear most at the counter are always the same: how does a bong work, which type should I get, how do I clean it, and are bongs legal in the UK?
This guide answers all of that in plain English: the main types (percolator, beaker, straight tube and mini glass bongs), how to use and clean one, what UK law actually says, and what to look for when comparing bongs for sale. If you are in Nottingham, you can also come and see our range in person.
Quick note before we start: High Rollers is an 18+ shop. Bongs are sold as smoking accessories for legal use with tobacco and herbal smoking blends, in line with UK law.
What is a glass bong?
A bong is a type of water pipe. Smoke is drawn through water before you inhale it, which is what makes it different from a hand pipe or a rolled cigarette. A glass bong is simply a bong made mainly from glass, rather than acrylic (plastic), silicone or ceramic.
Glass is the most popular material because:
- You can see when it needs cleaning. Clear glass shows build-up straight away.
- It does not add a taste. Glass is non-porous, so it does not hold on to old flavours.
- Better pieces use borosilicate glass, the type used in lab equipment. Its low thermal expansion makes it more resistant to sudden temperature changes than ordinary glass, though it can still crack if heated unevenly or knocked.
The trade-off: glass can break if dropped, so thicker glass and a stable base help.
How does a bong work?
Every bong, from the simplest straight tube to a multi-chamber percolator piece, works on the same basic idea.
The main parts of a bong
- Bowl: the small removable piece where the tobacco or herbal blend is packed and lit.
- Downstem: the tube that carries smoke from the bowl down into the water.
- Chamber (or tube): the main body of the bong, holding the water at the bottom.
- Mouthpiece: the opening at the top you inhale from.
- Carb hole (on some designs): a small hole you cover and uncover to control airflow. Many glass bongs skip this and use a pull-out bowl instead.
What happens when you inhale
Inhaling creates suction that pulls air through the lit bowl, down the downstem and out into the water as bubbles. The smoke rises through the chamber to the mouthpiece. Release the carb or lift the bowl and fresh air clears the chamber.
Water cools the smoke, which is why many people find a bong smoother than a pipe. But smoother does not mean safer: the World Health Organization is clear that passing smoke through water does not make it safe.
Types of glass bongs
There is no single “best bong”. The right one depends on how you will use it, your space and how much cleaning you are happy to do. These are the main styles in a UK head shop.
Beaker bongs
A beaker bong has a wide, cone-shaped base like a lab beaker. That makes it one of the most stable designs and a sensible first choice. The larger base also holds more water.
Straight tube bongs
One straight cylinder on a flat base. Simple, easy to clean and usually cheaper than complex designs, but the narrower base is less stable than a beaker.
Percolator bongs
Percolator bongs have an extra glass piece inside the chamber (the “perc”) that splits smoke into lots of smaller bubbles. Names like tree, honeycomb and showerhead perc describe its shape. More bubbles means a smoother draw; the downsides are more glass to clean, more weight and usually a higher price.
Mini glass bongs
Mini glass bongs are compact pieces, popular for small flats, easy storage and a lighter draw. They hold less water and can be more delicate.
Other styles you might see
You may also see glass bubblers (a cross between a hand pipe and a bong) and gravity bongs. Ask us how they differ.
How to use a bong (step by step)
Here is how to use a bong properly with a legal tobacco or herbal smoking blend:
- Add water. Fill with cool water until the end of the downstem sits about an inch under the surface. Too much and it splashes up; too little and the smoke will not pass through it.
- Test the draw. Inhale gently before lighting. You should hear bubbling and no water should reach your mouth.
- Pack the bowl loosely. Packed too tightly, air will not flow.
- Light and inhale slowly. Keep the bong steady on a flat surface, light the edge of the bowl and draw gently.
- Clear the chamber. Release the carb or lift the bowl and inhale the remaining smoke.
- Empty and rinse. Old water smells and stains glass quickly.
How to clean a bong
Change the water after every session and give it a proper clean regularly to keep the glass clear and stop stale smells.
What you need
- Isopropyl alcohol (the higher the percentage, the faster it works)
- Coarse salt (it acts as a scrub)
- A resealable bag for the bowl and downstem
- Pipe cleaners or a bottle brush
- Warm water
- Or a ready-made bong cleaning solution (such as the Blazy Susan Resin Blaster)
Step-by-step cleaning
- Take it apart. Remove the bowl and downstem and empty the water.
- Soak the small parts in a sealed bag with isopropyl alcohol and a spoonful of salt.
- Shake the chamber. Add alcohol and salt, cover the openings and shake gently. The salt scrubs; the alcohol dissolves residue.
- Scrub awkward spots with pipe cleaners or a brush.
- Rinse well with warm (not boiling) water until there is no alcohol smell, then dry fully.
Safety: never pour boiling water into cold glass (sudden temperature changes can crack it), and keep isopropyl alcohol well away from any flame.
Are bongs legal in the UK?
This is the question we get asked most, so here is the honest, careful answer. This is general information, not legal advice.
Buying and owning a bong. In the UK, bongs are sold legally as smoking accessories, and the Misuse of Drugs Act 1971 does not contain a general offence of simply owning one. Clean bongs used with tobacco or herbal blends are ordinary smoking accessories.
The law on supply (section 9A). Section 9A of the Misuse of Drugs Act 1971 makes it an offence to supply, or offer to supply, an article that may be used to take or prepare a controlled drug, if the seller believes it will be used for unlawful drug use. The drugs charity Release notes that items like bongs and grinders can fall within this section, and that a shop owner in Leeds was convicted in 2014 for selling bongs, bags and grinders. That is why responsible UK head shops sell bongs for legal use only and will not serve anyone who talks about using them with illegal drugs.
Residue. Cannabis is a Class B controlled drug in the UK. A bong containing measurable cannabis residue could be used as evidence in a possession case. Keep your glass clean and only use legal products.
Age. High Rollers only sells to adults aged 18 and over. Also worth knowing: under the Tobacco and Vapes Act 2026, from 1 January 2027 it becomes an offence in England and Wales to sell tobacco products, herbal smoking products or cigarette papers to anyone born on or after 1 January 2009. Expect to be asked for ID.
Glass bong buying tips: what makes the best bong?
Searching for the best bongs UK shoppers rate? These are the things that actually matter:
- Glass quality. Look for borosilicate glass with solid, even thickness.
- A stable base. Beaker and wide flat bases are less likely to tip.
- The right size. Mini glass bongs for compact storage; taller pieces hold more water.
- Ease of cleaning. Every extra percolator is another thing to clean.
- Removable parts. A removable bowl and downstem make cleaning and replacements easier. Check joint sizes match if you swap bowls.
- See it in person. Glass is worth holding before you buy, which is why a local bong shop near me beats guessing from a photo.

Glass bong FAQs
Are bongs legal in the UK?
Yes, bongs are legally sold in the UK as smoking accessories for use with tobacco and herbal blends. Section 9A of the Misuse of Drugs Act 1971 makes it an offence to supply one if the seller believes it will be used to take illegal drugs, so reputable shops sell for legal use only and to adults 18+.
Is it illegal to own a bong in the UK?
The Misuse of Drugs Act 1971 does not have a general offence of owning a bong. However, cannabis is a Class B drug, and a bong with measurable cannabis residue could be used as evidence of possession. Keep it clean and use legal products only.
How does a bong work?
You inhale through the mouthpiece, which pulls smoke from the lit bowl down the downstem and through water. The smoke bubbles up through the chamber, cooling on the way, and you clear it by releasing the carb or lifting the bowl. Cooler smoke is not safer smoke, though.
How do you clean a glass bong?
Empty it, take out the bowl and downstem, then shake isopropyl alcohol and coarse salt inside the chamber and soak the small parts in a sealed bag. Scrub tight spots with pipe cleaners and rinse thoroughly with warm, not boiling, water before drying.
What is a percolator bong?
A percolator bong has an extra glass piece inside the chamber that breaks the smoke into many small bubbles for a smoother draw. Common types include tree, honeycomb and showerhead percs. They need a bit more cleaning than simple designs.
