Thank you for the review! As no two bathroom layouts are identical, Aston Frameless Showers should be installed by professional, licensed contractors or experienced plumbers. The leaking you experienced sounds like an out-of-plumb issue with your alcoves flooring, which can be fixed with professional services. Should your team ever encounter difficulty with installation, we encourage you to write our specialized product support team at support@astonglobalinc.com. We hope you enjoy the design, quality and functionality of your MOSELLE Frameless Sliding Shower Door for years to come!
