FAQ
Q: What is GFRC and how does it compare to natural stone?
A: GFRC (Glass Fiber Reinforced Concrete) is molded from real stone boulders to replicate authentic texture and appearance. It weighs significantly less than natural stone while maintaining durability and weather resistance, making installation easier and more flexible.
Q: Should I choose the complete kit or rock only?
A: The complete kit (151 lbs) includes everything needed for installation—basin, pump, plumbing, and water treatment. The rock-only option (40-50 lbs) is ideal if you're replacing an existing fountain rock or building a custom system with your own components.
Q: How much water does the basin hold?
A: The 2×2 fountain basin holds 12 gallons, designed to accommodate the fountain's water circulation needs. Regular monitoring and occasional refilling maintain optimal operation.
Q: What's the difference between Dapple Gray and Chestnut?
A: Dapple Gray features soft gray tones with subtle mottling, while Chestnut offers warm earth tones with rich brown and amber hues. Both replicate natural stone coloration with organic variation.
Q: Can I add lighting to this fountain?
A: Yes, optional IllumiGlow® lighting kits are available for both exterior fountain lighting and interior plume lighting to create dramatic nighttime effects.
Q: Will the color match the photos exactly?
A: GFRC finishes replicate natural stone variations. Slight differences in tone and pattern are normal and contribute to the authentic, organic appearance of each handcrafted piece.
Q: Can this fountain withstand winter weather?
A: We recommend draining and winterizing the fountain in freezing climates. Store the pump indoors and protect the basin. The GFRC rock should be covered or stored to prevent freeze-thaw damage.
