Glass Bongs UK Sale – What to Buy Now
Looking for a glass bongs UK sale pick? For most buyers we would start with the Grace Glass 11 Arm Tree Perc bong: 50cm of borosilicate glass with an 11-arm tree perc, a 6-shooter diffuser downstem and ice notches. For something smaller and simpler, the 35cm Grace Glass Rasta Beaker and the 13in Liquid Sci Glass Double Showerhead beaker are the alternatives we would look at first.
Every bong in this glass bongs UK sale guide is in stock, and the full range, with far more styles and sizes than the seven here, sits in our Bongs category. This guide is built from our catalogue listings, comparing seven pieces from 13in to 50cm across five brands on height, joint size, percolation and box contents. First-timers usually do best with a simple beaker or straight tube; if you already own glass, a sale is the time to step up in wall thickness or filtration.
Key Takeaways
- Five of the seven bongs list an 18.8mm joint; the Liquid Sci Glass and Weed Star Popeye listings give no size in mm.
- Percolators (tree, spiral, showerhead) add filtration stages, but also add cleaning time and breakable points.
- Best for beginners: the 35cm Grace Glass Rasta Beaker. Simplest to clean: the Weed Star Popeye, which has no perc.
- Wall thickness is listed at 4mm on the Rasta Beaker and Amsterdam, and about 3.2mm on the Art Glass Jackknife.
- The Dude Bongs Lean Back set is the only piece here with a grinder, lighter, screens and carry box.
- All bongs are sold to adults (18+) only.
Glass bongs UK sale: seven bong deals compared
Before comparing prices, compare height, joint size and box contents, because photos can make every piece look bigger than it is. Our three main picks come from Grace Glass and Liquid Science Glass; four alternatives cover a second tree perc beaker, a plain straight tube, a gift set and a folded cylinder.
| Bong | Height | Style / percolation | Joint / glass | Price |
|---|---|---|---|---|
| Grace Glass 11 Arm Tree Perc | 50cm | Cylinder, 11-arm tree perc + 6-shooter downstem | 18.8mm bowl / borosilicate | Original price was: £69.95.£39.95Current price is: £39.95. |
| Grace Glass Rasta Beaker | 35cm | Beaker, coiled spiral perc | 18.8mm female / 4mm borosilicate | Original price was: £69.99.£39.95Current price is: £39.95. |
| Liquid Sci Glass Double Showerhead | 13in | Beaker, double showerhead perc, splash guard | Not stated | Original price was: £99.00.£69.99Current price is: £69.99. |

Grace Glass 11 Arm Tree Perc: the main pick
The Grace Glass cylinder bong is the tallest piece here at 50cm, and it filters in two stages: first through a 29.2mm 6-shooter diffuser downstem (about 12cm long), then through an 11-arm slitted, reinforced tree perc. It also has ice notches, an 18.8mm bowl with handle and a rubber carb stopper with carb hole. The weakness is size: at 50cm it needs shelf space, and 11 arms take longer to clean than a plain tube. If you want low upkeep, the Weed Star Popeye is the better choice.

At 35cm, the Rasta Beaker is easier to store and handle than the 50cm tree perc, and its beaker base adds stability. It is made from 4mm borosilicate glass, with a removable diffused downstem, a coiled spiral perc and three ice pinches, plus an 18.8mm male flower bowl for its 18.8mm female joint. Choose the tree perc model if you want more filtration; choose this if you want a smaller first bong.
Liquid Sci Glass 13in Double Showerhead: the compact option
The Liquid Sci Glass beaker is the most compact of our three picks at 13 inches, with a double showerhead perc, built-in splash guard and three ice notches. Its diffuser downstem is fixed, so there is one less part to lose, but you cannot remove it for cleaning. The box includes a female 18.8mm nail, yet the listing does not state the bong's own joint size, so check before buying extra bowls.
Four alternatives, and when they win
The Amsterdam 8-Arm Tree Perc from Dope Bros by Grace Glass is a 14in beaker with 4mm glass, a removable diffuser downstem, an 8-arm tree perc and three ice pinches. It is a smaller take on the main pick, though the listing calls it 'borosilicate-style' glass and lists only Black and Green. The Weed Star Popeye is a 39cm borosilicate straight tube with no percolator, which makes it the quickest to clean in this guide.
The Dude Bongs Lean Back Ice Twist set is the gift pick: a 41cm sci-glass bong with an 18.8mm joint, plus a Shark teeth grinder, branded lighter, 5 pipe screens and a custom aluminium carry box. The Art Glass Jackknife is a straight cylinder with a midpoint fold that doubles as an ice notch, but its glass is about 3.2mm, thinner than the 4mm Rasta Beaker and Amsterdam.
What actually matters when comparing sale glass bongs
Shape matters too. Beaker bongs have a stable base and a forgiving design, which is why three of our seven picks use one, while straight tubes such as the 39cm Weed Star Popeye have a neater footprint. Every piece in this guide is glass; if you are weighing glass against acrylic or silicone, our guide to bong types covers the wider range.
Glass thickness is where spending a little more during a sale can make sense. Listings here range from about 3.2mm on the Art Glass Jackknife to 4mm on the Rasta Beaker and Amsterdam, and thicker walls give more confidence when handling and cleaning. Borosilicate glass bongs are the norm, though the Amsterdam is described only as 'borosilicate-style' glass and the Dude Bongs piece as sci-glass. No wall thickness makes a bong unbreakable.
Cheap glass bongs UK: best picks for beginners and tight budgets
On a tight budget, pay for function rather than extras. The Weed Star Popeye ( Original price was: £69.99.£29.95Current price is: £29.95.) and the Art Glass Jackknife ( Original price was: £39.95.£19.95Current price is: £19.95.) are the simplest glass here, with no percolator listed and a bowl piece included. If you want a perc without the 50cm height, the Amsterdam ( Original price was: £74.95.£29.95Current price is: £29.95.) adds an 8-arm tree and three ice pinches at 14in.
For a first bong, we would point most buyers at the 35cm Rasta Beaker ( Original price was: £69.99.£39.95Current price is: £39.95.): a stable beaker base, 4mm borosilicate, a removable downstem and standard 18.8mm fittings. The 50cm Grace Glass tree perc is the upgrade once you know you will keep up with cleaning 11 arms. For a gift, the Dude Bongs set ( Original price was: £39.95.£29.95Current price is: £29.95.) arrives with a grinder, lighter and screens as well as the bowl.
When extra features are worth it
Tree, spiral and showerhead percs add filtration stages; our percolator bongs comparison covers each type. The green 11-arm tree perc bong pairs a perc with a diffuser downstem, the Rasta Beaker uses a coiled spiral and the Liquid Sci a double showerhead. More internal structure means more cleaning, so for a quick rinse a plain chamber like the Popeye suits better. Ice notches are the simpler extra: six of the seven bongs here have them.
Cleaning a glass bong
Cleaning time scales with complexity: a straight tube with no perc needs far less work than an 11-arm tree perc or a double showerhead. Removable downstems on the Grace Glass and Amsterdam pieces come out for separate cleaning, while the Liquid Sci's fixed downstem stays in place. A basic routine looks like this, and our bong cleaning guide covers it in full.
- 1. Empty the water and remove the bowl and any removable downstem.
- 2. Rinse the chamber and every part with warm water.
- 3. Soak or shake with isopropyl alcohol or a dedicated bong cleaner, using a long brush such as the Black Leaf bendable cleaning brush for tall tubes and perc arms.
- 4. Rinse thoroughly with water until no cleaner remains, then let every part dry before reassembling.

What size joint is a standard bong?
18.8mm is the most common joint in our range: the Grace Glass, Amsterdam, Dude Bongs and Art Glass pieces in this guide all use it. Check each listing, as the Weed Star Popeye is described only as 'standard' and the Liquid Sci Glass joint size is not stated.
Is borosilicate glass better for bongs?
Borosilicate is the material listed for most bongs here, including the 4mm-thick Grace Glass Rasta Beaker. Wall thickness matters as much as glass type: thicker walls feel more reassuring to handle and clean.
What does a tree percolator do?
It splits the smoke through several slitted arms in the water, adding a filtration stage before the tube. The Grace Glass model has 11 arms and the Amsterdam has 8; more arms mean more to clean.
Do you need ice in a bong?
No, it is optional. Ice notches or pinches hold ice in the tube to cool the smoke, and six of the seven bongs in this guide have them.
What comes included with a bong?
It varies. The Grace Glass 11 Arm Tree Perc includes a diffuser downstem, an 18.8mm bowl with handle and a carb stopper, while the Dude Bongs Lean Back set adds a grinder, lighter, 5 screens and an aluminium carry box.
