5. Resort-Style Lagoon Pool with Rock Grotto Waterfall
Introduction
Bring a tropical Hawaii or Bali resort directly to your backyard with a freeform lagoon pool featuring custom faux-rock waterfalls, hidden grottos, and lush tropical planting.
What This Idea Means
This design celebrates exotic escapism, organic curves, and adventurous water play. It turns your backyard into an immersive vacation resort complete with hidden water caves.
How to Make It
- Freeform Excavation: Excavate an organic, kidney-shaped or sweeping curved pool basin with varying depth shelves.
- Rockwork Construction: Build custom structural faux-rock grotto caves and cascading waterfalls using shotcrete molded over reinforced steel frames and stained by hand.
- Tropical Planting: Surround the lagoon edge with lush tropical foliage such as banana plants, bird of paradise, and massive-leafed monsteras.
- Pebble Interior: Finish the pool interior with a multicolored pebble aggregate that mimics a natural riverbed floor.
Tips and Variations
- Tip: Hide a built-in stone bench inside the hidden water grotto cave so swimmers can sit behind the cascading waterfall wall.
- Variation: Add a stone slide built directly into the artificial rock grotto for high-energy family fun.
