about us
Dream, Create, Relax
Since 1989, Splash Supply Company has been crafting naturalistic, eco-friendly landscapes across York County in South Central Pennsylvania and beyond. What began as a one-man operation in the late 1980s has grown into the region’s largest pond and waterfall display garden and retail store. We provide DIY and design build services throughout Pennsylvania and Maryland.
Over the past three decades, our team has designed and installed hundreds of water features, ranging from custom interior water walls and charming backyard waterfalls to show-stopping fountains and the impressive koi pond at the entrance of York’s newest hospital. Our work has earned national recognition, showcasing on television shows and in major trade magazines.
Founded by Mark Willoughby, who studied landscape architecture at West Virginia University, Splash Supply Company has built its expertise through hands-on experience—experimenting, learning, and perfecting waterfall and pond design. Our passion lies in creating naturalistic outdoor spaces where you can relax and reconnect with nature.
We invite you to DREAM as you explore our expansive display gardens and see firsthand what we can CREATE for you, so you can RELAX in your own backyard!
Whether you’re dreaming of an acre-sized lake or just want to enjoy the sounds of a small trickling waterfall, we can’t wait to get started on your personal oasis.
