GRAV Coil Showerhead Water Pipe – 12.25" Coil Perc Bong

The GRAV Coil Showerhead Water Pipe is a 12.25" borosilicate bong that cools smoke in three stages instead of one. Smoke first passes through a vertical tube below the bowl that strips ash and resin, then travels the length of a long glass coil — a visible spiral that buys the smoke time to cool — and finally exits through a showerhead percolator with 13 cuts at the base of the chamber. The rising bubbles then break against the submerged lower coils, which kills splashback and adds a final round of diffusion. The GRAV Coil Showerhead Water Pipe is stemless, uses a 14mm female joint at 90 degrees, and includes a 14mm GRAV Funnel Bowl.

⚡ At-a-Glance Decision Summary

• What it is: A 12.25" clear borosilicate tabletop bong with a coil percolator and a 13-cut showerhead perc, on a heavy disc base.
• Why choose it: Three cooling stages in one pipe, and a draw that owners consistently describe as the smoothest they have used.
• The differentiator: The coil works twice. Smoke travels down through it to cool, then the bubbles rise and break against the submerged lower turns — extra diffusion and no splashback, from the same piece of glass.
• Joint: 14mm female at 90 degrees, so every 14mm 90° bowl and banger at Angies Boutique fits.
• Stemless: The smoke path is built into the glass. Nothing to lose, nothing to knock loose.
• Water: Approximately 3 inches — noticeably more than a standard beaker, and the perc depends on it.
• Included: A 14mm GRAV Funnel Bowl.
• Confidence signal: $199.99, matching GRAV's own retail price exactly. Bought direct from GRAV by an authorized dealer.

Summary: The GRAV Coil Showerhead Water Pipe is a 12.25" stemless bong combining a coil perc, a 13-cut showerhead, and a 14mm 90° joint.

🧠 Our Verdict

Buy the GRAV Coil Showerhead Water Pipe if smoothness is the thing you care about most — three stages of cooling in a single stemless piece is more filtration than anything else in this catalogue at any price.

Quick Summary

The GRAV Coil Showerhead Water Pipe stands 12.25" tall and 5" across on a heavy disc base. Smoke leaves the bowl through a vertical ash-catching tube, spirals the length of a long glass coil, and exits through a 13-cut showerhead percolator into water. Bubbles rising from the showerhead break against the submerged lower coils for extra diffusion and no splashback. The GRAV Coil Showerhead Water Pipe is stemless, takes roughly 3 inches of water, uses a 14mm female joint at 90 degrees, and includes a 14mm GRAV Funnel Bowl. Price: $199.99.

GRAV Coil Showerhead Water Pipe – Three Stages of Cooling in One Chamber

Most bongs cool smoke once. The smoke goes through water, the water takes the heat, and that is the whole mechanism. The GRAV Coil Showerhead Water Pipe puts three separate stages between the bowl and your mouth, and each one does a different job.

Stage one is a vertical tube directly below the bowl. Smoke enters it and ash and resin drop out immediately, before they ever reach the water. That keeps the water cleaner for longer and it means less of what you are inhaling is particulate. Stage two is the coil. Smoke spirals the full length of a long glass helix, and length is the point — every extra inch of glass is more time in contact with room-temperature material, so the smoke arrives at the water already substantially cooler. It is also the part people watch, because the spiral is visible from across a room. Stage three is a showerhead percolator with 13 cuts at the base of the chamber, which breaks the smoke into thirteen streams and pushes it into the water.

Then the clever part. The bubbles rise, and on the way up they hit the lower turns of the coil, which sit submerged. Those coils break the bubbles apart a second time and physically block water from climbing the chamber. The coil is a cooling pathway on the way down and a diffuser-plus-splashguard on the way up, and GRAV got both out of one piece of glass. The rest of the range sits in our GRAV collection.

The GRAV Coil Showerhead Water Pipe is stemless — the entire path is fused into the body, so there is no downstem to knock out, lose, or break. It stands on a thick disc base wide enough to make a 12.25" pipe genuinely stable.

Summary: The GRAV Coil Showerhead Water Pipe stacks an ash-catching tube, a long cooling coil, and a 13-cut showerhead perc into one stemless chamber.

⭐ Who This Product Is For / Not For

Ideal for:

• Anyone whose main complaint is harshness. Three stages of cooling is the most filtration in this catalogue, and owners repeatedly describe the GRAV Coil Showerhead Water Pipe as the smoothest piece they have used.
• People who used to need ice. The coil does the work ice usually does, without diluting or dripping.
• Big-hit smokers. The chamber is large, the draw is effortless, and the pipe is built for long pulls.
• Anyone who wants a display piece. The spiral is the visual — smoke travelling through the coil is the reason this one lives on the table rather than in a cupboard.
• 14mm 90° accessory owners. Every 14mm 90° bowl and quartz banger at Angies Boutique fits the GRAV Coil Showerhead Water Pipe.
• People tired of losing downstems. Stemless means there is nothing to misplace or snap.

Not recommended for:

• Anyone who wants a removable downstem. The GRAV Coil Showerhead Water Pipe is stemless, so the smoke path cannot be swapped, upgraded, or pulled out for cleaning.
• Portability. 12.25" of heavy borosilicate on a wide disc base. This is a tabletop piece.
• Ice users. There is no ice pinch, and the design does not need one.
• Anyone who under-fills. The GRAV Coil Showerhead Water Pipe needs roughly 3 inches of water — more than a standard beaker — and the perc does not work properly below that.
• Tight budgets. At $199.99 this is the most expensive GRAV piece in the range.
• Anyone wanting colour. Stocked in clear with a GRAV decal.

Summary: The GRAV Coil Showerhead Water Pipe suits smoothness-first home use on 14mm 90° hardware and does not suit portability or downstem swapping.

⚠️ Known Limitations

• Stemless means permanent. The coil, the vertical tube and the showerhead are all fused into the body of the GRAV Coil Showerhead Water Pipe. Nothing comes apart except the bowl, so cleaning is a soaking job and a damaged perc is not replaceable.
• It needs about 3 inches of water. That is more than most bongs this size, and it is not optional — the showerhead sits at the base of the chamber and the lower coils have to be submerged for the design to work.
• A long path collects more residue. A coil has far more internal surface than a straight downstem. Owners report it cleans more easily than expected, but it still needs isopropyl and salt on a schedule.
• No ice pinch. The coil replaces it.
• Heavy and tall. The GRAV Coil Showerhead Water Pipe is 12.25" of thick borosilicate. Stable on a table, awkward anywhere else.
• Height is listed inconsistently across the market. GRAV's own dimensioned drawing gives 12.25"; some retailers list 13" or 14". The drawing is the figure used here.
• Clear only. No colourways stocked.

Summary: The GRAV Coil Showerhead Water Pipe trades serviceability and portability for three-stage filtration, and it needs a high water line.

⚙️ Features & Benefits

• Coil percolator: A long glass helix that extends the smoke path dramatically. More distance means more cooling before the smoke ever reaches water, and the spiral is visible while you draw.
• 13-cut showerhead perc: Sits at the base of the chamber and splits the smoke into thirteen streams. This is where the heavy diffusion happens on the GRAV Coil Showerhead Water Pipe.
• Submerged lower coils: Rising bubbles break against them for a second round of diffusion, and the same coils physically block water from reaching the mouthpiece.
• Vertical ash-catching tube: Strips ash and resin directly below the bowl, before the water. Cleaner water, cleaner hits.
• Stemless construction: The whole path is fused into the glass. Nothing to lose, nothing to knock loose, no joint to leak.
• Effortless draw: The most consistent thing owners say about the GRAV Coil Showerhead Water Pipe is how little effort a full pull takes.
• Heavy 5mm-thick borosilicate on 60mm tubing: Substantial glass, built for daily use.
• Wide disc base: Keeps a tall pipe planted.
• 14mm female joint at 90 degrees: The standard configuration, so 14mm 90° bowls and bangers drop straight in.
• 14mm GRAV Funnel Bowl included: A deep cone that holds a generous pack.

Summary: A coil perc, a 13-cut showerhead, an ash-catching tube and stemless construction define the GRAV Coil Showerhead Water Pipe.

📐 Structured Specs

Summary: The GRAV Coil Showerhead Water Pipe measures 12.25" on 60mm tubing with a stemless coil-and-showerhead path and a 14mm 90° joint.

🔌 Compatibility & Requirements

Compatible with:

• Any 14mm male bowl at 90°. The included Funnel Bowl is the intended slide. The GRAV Cup Bowl in 14mm and the GRAV 14mm Caldera Bowl both fit.
• Any 14mm male quartz banger at 90°. The GRAV Seamless Quartz Banger, the GRAV Quartz Control Tower Banger Set and the GRAV Quartz Slurper Bucket Set are all 14mm 90° and all fit the GRAV Coil Showerhead Water Pipe.
• 14mm ash catchers such as the GRAV 14mm Standard Ash Catcher, though the integrated vertical tube already handles most of that job.
• Isopropyl alcohol and coarse salt. Borosilicate tolerates both. Dr. Dabber ISO Snaps handle the bowl and banger between soaks.

NOT compatible with:

• 10mm, 18mm and 19mm accessories. The joint on the GRAV Coil Showerhead Water Pipe is 14mm only.
• 45° bangers. This joint is 90°, so a 45° banger sits crooked. The GRAV Quartz Bucket is the 45° piece in the GRAV quartz range and does not suit this pipe.
• Replacement downstems. The GRAV Coil Showerhead Water Pipe is stemless. There is no downstem to replace.
• Ice. No pinch, and the coil already does that job.
• Dishwashers and boiling water. Neither is safe for a percolated piece.

Summary: The GRAV Coil Showerhead Water Pipe accepts any 14mm male 90° bowl or banger and rejects other joint sizes, 45° quartz, and downstem swaps.

🧼 How to Use & Troubleshooting

Setting up the GRAV Coil Showerhead Water Pipe:

1. Rinse with warm water before first use.
2. Add water through the mouthpiece until the chamber holds roughly 3 inches — enough to cover the showerhead perc and submerge the lower coils. This is more water than a standard beaker takes, and it is what the design depends on.
3. Seat the included 14mm Funnel Bowl. It should sit snug without force.
4. Pack the bowl. The funnel shape holds a generous amount.
5. Draw steadily and watch the coil. Seeing the smoke spiral through the glass tells you the path is clear and the fill is right.
6. Pull the bowl to clear. The pull is deliberately light, so pace yourself on the first few sessions.

Running concentrate: Remove the Funnel Bowl and seat a 14mm male 90° quartz banger. Heat, let the banger cool to temperature, apply concentrate, and cap. Three stages of filtration cool vapour thoroughly, so short draws are plenty on the GRAV Coil Showerhead Water Pipe.

Troubleshooting:

• Problem: weak or no percolation. Solution: the water is below the showerhead. Top up to roughly 3 inches. This is the single most common mistake on this pipe.
• Problem: water reaching the mouthpiece. Solution: overfilled past the point the submerged coils can block. Pour down to 3 inches.
• Problem: heavy drag. Solution: either too much water, or resin has narrowed the coil. A coil has more internal surface than a downstem, so it needs a soak sooner.
• Problem: the coil looks cloudy and rinsing does nothing. Solution: fill with isopropyl and coarse salt, cover both openings, and shake so the solution travels the full spiral. Let it sit and repeat — no brush reaches inside a coil.
• Problem: ash in the water. Solution: the flower is ground too fine and is passing the vertical tube. Grind coarser, or add a screen to the bowl.
• Problem: the bowl sticks. Solution: resin in the joint. Twist gently while pulling; never lever it sideways.

Summary: Fill the GRAV Coil Showerhead Water Pipe to 3 inches, watch the coil to confirm flow, and clean by soaking rather than scrubbing.

⚖️ Comparison Table

How to read this table. The GRAV Coil Showerhead Water Pipe is $50 more than the Upline at almost identical height, and the money buys filtration rather than height — three stages against the Upline's ladder perc. The Upline is the flavour pick, because staged restrictions preserve terpene character; the Coil Showerhead is the smoothness pick, because more diffusion means a softer hit. The Helix adds a Venturi vortex and a removable downstem for $50 less. The Medium Round Base is the practical, serviceable option at $119.99 with an ice pinch.

Summary: Against the rest of the GRAV bong range, the GRAV Coil Showerhead Water Pipe buys maximum smoothness at the cost of serviceability.

💬 Common Questions & Answers

How does the coil perc actually work?
The coil is a long glass helix that dramatically extends the distance smoke travels before it reaches your mouth. Length is the entire mechanism — every extra inch of glass is more time for heat to transfer out of the smoke and into room-temperature material. On the GRAV Coil Showerhead Water Pipe the smoke spirals down the coil, exits through a 13-cut showerhead perc into the water, and then the rising bubbles break against the submerged lower turns of that same coil. The coil cools on the way down and diffuses on the way up.

How much water does it need?
Roughly 3 inches — noticeably more than a standard beaker of similar size. The showerhead percolator sits at the base of the chamber and needs to be fully covered, and the lower turns of the coil need to be submerged for the anti-splashback effect to work. Under-filling the GRAV Coil Showerhead Water Pipe is the most common mistake, and it produces exactly the harsh, unfiltered hit the piece exists to prevent. Fill to about 3 inches, and check the coil is spiralling when you draw.

What does "stemless" mean, and is it a downside?
Stemless means there is no separate removable downstem — the vertical tube, the coil and the showerhead perc are all fused into the body of the GRAV Coil Showerhead Water Pipe. The upside is that nothing can be knocked loose, lost, or broken at a joint, and there is no seal to leak. The downside is that the smoke path cannot be swapped for a different perc, and cleaning is done with the pipe intact using isopropyl and salt rather than by taking it apart.

Will my quartz banger fit?
If it is 14mm male at 90 degrees, yes. The GRAV Coil Showerhead Water Pipe uses a 14mm female joint at 90 degrees, which is the most common banger configuration, so the GRAV Seamless Quartz Banger, the GRAV Quartz Control Tower Banger Set and the GRAV Quartz Slurper Bucket Set all fit correctly. Avoid 45 degree bangers — a 45 degree piece seated in a 90 degree joint leans and runs concentrate toward the joint rather than pooling in the bucket.

Is a coil hard to clean?
A coil has considerably more internal surface than a straight downstem, so it collects residue faster in absolute terms. In practice owners report it cleans more easily than they expected, because the coil is a smooth continuous tube with no slots or narrow apertures to trap material. The method is isopropyl alcohol and coarse salt, with both openings covered so the solution travels the full spiral, then a soak. Repeat soaks work better than force on the GRAV Coil Showerhead Water Pipe.

Do I still need ice?
No, and there is no ice pinch to hold any. The three cooling stages on the GRAV Coil Showerhead Water Pipe — the vertical ash tube, the extended coil, and the showerhead diffusion — do the work that ice normally does, without the dilution, the dripping, or the thermal shock risk that ice introduces to percolated glass. Owners moving from ice-catcher bongs consistently report they stopped bothering with ice after switching to this piece.

How tall is it really?
12.25 inches, and 5 inches across at its widest point on a roughly 4-inch disc base. Retailers list this piece anywhere from 12.5 to 14 inches, and GRAV's own product copy says 14 inches — but GRAV's dimensioned technical drawing gives 12.25 inches, so that is the figure used here. It is built on 60mm tubing with 5mm walls, which makes the GRAV Coil Showerhead Water Pipe considerably heavier than the height alone suggests.

Summary: The GRAV Coil Showerhead Water Pipe needs 3 inches of water, takes 14mm 90° accessories, is stemless, and replaces the need for ice.
