This GRAV® Straight-Based Water Pipe is 8″ tall and made on 32mm tubing. Its downstem ends in a broad orb perc that diffuses smoke through water and is fixed inside the pipe to prevent damage. The tiered body keeps water from splashing out of the piece. The straight-based water pipe comes ready to use with a 14mm GRAV® Cup Bowl and functions best with approximately 1.5″ of water.
