In this buyer’s guide, we will explore the myriad of large outdoor rock water fountains available from Fountainful including the GFRC Boulder Collection — handmade boulders that offer the charm and durability of natural rock without the hefty weight — and the Natural Collection, which features natural, quarried rock for those seeking the authenticity of raw nature. From considering different sizes and types of stone to strategic placement tips, we’ll help you navigate the choices and find the perfect large outdoor rock water fountain that complements your space.

What is the best material for outdoor fountains?

The best material for large outdoor rock water fountains depends on the climate and the aesthetic you're aiming for. Natural stone and GFRC (Glass Fiber Reinforced Concrete) are among the most popular due to their durability and natural appearance. Stone provides a classic, timeless look, while GFRC is lighter, easier to mold into intricate designs, and less susceptible to weathering. Both materials are excellent for creating stunning, long-lasting outdoor fountains.

Pro Tip: Add a Sediment Screen to your natural stone water fountain order for added protection – the Sediment Screen is especially helpful in areas prone to falling leaves, beetles, and June bugs.

Large Outdoor Rock Water Fountains FAQ

Do outdoor fountains use a lot of electricity?

Large outdoor rock water fountains do require electricity to run the pump, but they do not typically consume a lot of power. Modern fountain pumps are designed to be energy-efficient. The actual electricity consumption will depend on the size of the pump and how frequently the fountain is operated. Using timers or adjusting the pump's settings can help reduce electricity usage further.

How do I keep my outdoor fountain water clean naturally?

Keeping large outdoor rock water fountain water clean naturally involves a few key practices:

  1. Regularly remove debris.
  2. Use a pump with a filter to keep the water circulating.
  3. Introduce natural water cleaners like barley straw pellets, which release enzymes that help break down algae without harming plants or wildlife.
  4. Avoid chemicals and opt for natural algae inhibitors.
  5. Occasionally, drain and scrub the fountain with a brush and a mixture of water and vinegar to remove algae buildup.

Should you leave an outdoor fountain on all the time?

Leaving an outdoor fountain running continuously can extend the pump's life and prevent algae and bacteria by keeping the water fresh. However, using a timer to operate the fountain during daytime hours or when most likely to be enjoyed can save energy and water.
