A trough drain shower features a long, narrow drain channel built into the floor instead of a traditional point drain. This channel slopes gently towards the drain, allowing water to flow easily away from the shower area. Trough drains are typically wider and more shallow than point drains, providing a sleek, modern look and making it easier to clean hair and debris. They are also customizable, allowing for a wide range of lengths, styles, and materials to match any bathroom design.
