Mountain Spring Boulder Fountain Kit
Bring the movement and sound of a natural mountain spring into your landscape. Water bubbles from the top of a broad, tiered boulder and cascades over textured stone-like ledges. Available in the full-size Mountain Spring or the compact Mini.
Instead of falling from a single outlet, water moves over multiple stepped ledges, creating layered movement and a natural spring sound. Each boulder is molded from natural rock and hand-finished by Blue Thumb in GFRC (glass fiber reinforced concrete), capturing realistic stone texture in a hollow, manageable structure — about 75 lbs for the full-size rock and 40 lbs for the Mini.
The Mountain Spring (36" x 24" x 24" H) is a broad garden centerpiece; the Mini Mountain Spring (22" x 20" x 15" H) brings the same look to smaller beds and patios.
Water steps down textured ledges for layered sound.
24" or 15" tall to fit your space.
Dapple Gray or Chestnut Brown finish.
Boulder, basin, pump, and plumbing included.

Both sizes come in Dapple Gray or Chestnut Brown. Polished pebbles (40 lb bags) are sold separately.
How much space do I need?
The full-size kit's buried basin is about 49" square; the Mini's is 30" round. Allow extra room for excavation, decorative stone, and possible overspray.
Can I adjust the sound and flow?
Yes. The full-size kit includes a ball valve to fine-tune water movement. Test the flow before finishing the decorative stone.
Do I need a permanent water line?
No. The fountain recirculates from its basin; just top it off periodically, or add an auto-fill kit.
What about winter?
In freezing climates, disconnect the pump and store it in water above freezing. Leave the basin about half full. The GFRC rock can stay outdoors.
