About GFRC Bubbling Boulders

The GRFC bubbling boulders have a very natural look and texture, and Blue Thumb's quality construction ensures many years of enjoyment, yet these fountains weigh hundreds of pounds less than identical "real" stone!   Each of Blue Thumb's GFRC boulder fountains are designed and hand-crafted specifically to make an eye-catching water feature. 

Your Choice of Color

Blue Thumb GFRC fountains come in your choice of:

  • Dapple Gray with Black polished pebbles
  • Chestnut with Mixed polished pebbles

Both colors have been uniquely crafted and tested in Blue Thumb's labs to obtain the most natural, real-stone look both wet and dry.
