GRAV 6" Round Base

The GRAV Labs 6 Inch Round Base is a mini water bong designed to support hard-hitting, potent smoke sessions. Don’t be fooled by its compact, convenient size - the GRAV Labs 6 Inch Round Base is capable of holding lots of smoke thanks to its optimized globe shape. You’ll be surprised at the potent punch this 6 inch powerhouse is capable of packing.

Crafted from high-quality glass and featuring a fixed downstem with a flat base, the GRAV Labs 6” Round Base water pipe is easy to use, easy to clean, and easy to get smooth, cool hits from. 

Top 5 GRAV Labs 6” Round Base Features

Fixed Fission Downstem

The 6” Round Base Bong features a fission downstem that diffuses smoke through the water for clean, cool hits. This downstem is fixed inside the pipe to prevent damage, and makes for an easy cleaning process.

Ergonomic Mouthpiece 

Designed to support ultimate comfort and zero waste, GRAV Labs designed a rounded mouthpiece for the 6” water pipe that makes it even more satisfying and comfortable to take a hit from.

Round Flat Base

The flat base allows for improved safety and proper storage, as this water bong can be placed on any desk, coffee table, or flat surface without tipping over accidentally. 

Premium Borosilicate Glass 

This water pipe bong is constructed with premium quality borosilicate glass, which adds to its overall durability by increasing its resistance to damage. This glass also allows for particularly easy maintenance, which means your unit can look sparkling clean at all times. 

Portable Size

The compact size of the mini water pipe bong makes it highly portable, coming in at only 6 inches tall. This makes it perfect for bringing along to parties to share with friends or packing safely in luggage before going on a trip.

How to use the Grav Labs Mini Round Base Water Pipe

1. How to operate the Grav Labs 6” Round Base

Pour about an inch of water into the bong, and take a few test rips to ensure there’s no splashback. 

Then, grind your herbs to your preferred consistency and load them into the bowl. From there, just place your lips against the mouthpiece, light the herbs using a lighter, and slowly start inhaling. 

2. How to get cool hits from the Grav Labs 6” Round Base

For cool, satisfying hits, it's important not to overfill or underfill the 10mm GRAV Cup Bowl. As we’ve mentioned, one inch of water works best with this mini glass pipe bong.

Also, be sure to pack your dry herbs into the bowl properly, as too little or too much will negatively affect airflow and result in less smoke and less satisfying hits. 

Proper maintenance of your unit is also essential in ensuring high-quality smoke sessions, which is why it’s important to clean your water pipe after every few uses (and use fresh water every time)

3. How to clean the Grav Labs 6” Round Base

Follow these steps to properly clean your Grav Labs 6 Inch Mini Bong: 

  • Mix a solution containing isopropyl alcohol and coarse salt
  • Fill the pipe a little more than halfway with the solution
  • Seal off openings
  • Shake the water pipe vigorously for three minutes
  • Empty the solution from the pipe
  • Rinse the pipe off with hot water, then cold water
  • Allow the water pipe to dry completely before using again
