You’ve found the perfect fountain design. It looks like an antique stone masterpiece. But then you read the description: "Material: Polyresin."
Or maybe you are staring at a gorgeous 3-tier centerpiece, but the weight says "400 lbs" (Concrete).
Which one should you buy?
At WaterFountainOnline, we sell both, and we love both—but for very different reasons. Choosing the wrong material can lead to cracked bowls in winter or a fountain that keeps blowing over in the wind.
In this guide, we break down the Resin vs. Concrete battle to help you make the right choice for your lifestyle and climate.
Contender 1: Cast Stone (Concrete)
The "Forever" Choice
Cast stone is essentially refined concrete. It is poured into molds and finished to look like natural limestone, sandstone, or granite.
🏆 The Pros:
- Unmatched Durability: A concrete fountain is a permanent investment. With proper care, it can last 50+ years, often becoming a family heirloom.
- Timeless Aging: Unlike plastic, concrete gets better with age. It develops a natural patina and moss growth that blends seamlessly into a mature garden.
- Wind Resistance: These fountains are heavy. A strong storm won't budge them.
⚠️ The Cons:
- The Weight: Once you place it, it stays there. You might need a team (or a forklift) to install larger models.
- Winter Care: Concrete is porous. If water freezes inside the bowl, it will crack. You must drain and cover it in freezing climates.
Contender 2: Polyresin (Fiberglass)
The "Modern" Master
Polyresin is a durable compound (often reinforced with fiberglass) that can be molded to mimic any texture—from rough stone to smooth ceramic or rotting wood—at a fraction of the weight.
🏆 The Pros:
- Incredible Detail: Resin captures intricate details (like bird feathers or tree bark) that concrete cannot.
- Lightweight & Portable: Renting a home? Like to rearrange your patio? You can pick up a resin fountain and move it yourself.
- Easy Installation: No contractors needed. Unbox, plug, and play.
- Price: Generally 30-50% cheaper than cast stone.
⚠️ The Cons:
- UV Fading: Over 5-10 years, harsh sunlight can fade the paint finish (though a clear UV spray helps).
- Stability: Because they are light, they can tip over in high winds if not weighted down with sand or stones.

The Verdict: Who Wins?
Choose Concrete (Cast Stone) If:
- You own your home and want a permanent garden centerpiece.
- You live in a windy area where stability is key.
- You love the "Old World" look of weathering stone and moss.
- Recommendation: [Browse Our Concrete Collection]
Choose Resin If:
- You are a renter or plan to move soon.
- You want a fountain for a deck or balcony (where weight limits matter).
- You want realistic "nature" designs (like tree trunks or animals).
- You want an easy, DIY setup without heavy lifting.
- Recommendation: [Browse Our Resin Collection]
Expert Maintenance Tip (Bonus)
- For Resin: Buy a can of "Clear Matte UV Resistant Spray" from a hardware store. Spray your fountain once a year to keep the colors vibrant.
- For Concrete: Apply a "Concrete Sealer" every 3 years to prevent water absorption and freeze-cracks.
Conclusion
There is no "bad" material, only the wrong application. Whether you choose the permanence of stone or the versatility of resin, both will bring the soothing sound of water to your sanctuary.
