Repel Systems, LLC is a building-materials supplier founded in Louisville, Kentucky, in 2018. The company works with Anhui JIT New Materials Co., Ltd. in China to import lightweight, easy-to-install shower products for custom bathroom tile projects. Its materials are designed for a range of construction applications, with a focus on preparing and finishing tiled wet areas.

The product range includes Repel tile backerboard, heat board, slotted curved board, prefabricated XPS niches, curbs, and complete shower systems. Shower options include square-drain and linear-drain systems, as well as walk-in shower pans. The pans help create floor falls for tiled showers and can also be used in settings such as wet rooms, balconies, and roof terraces. Their coated surface is designed to receive tile, while backerboard can be used as a raising course to form accurate falls over longer distances.

Repel Systems also provides product catalogs, brochures, installation videos, testing documents, and warranty information to support customers and installers. Its office is located on Schuff Avenue in Louisville.
