A neo-angle shower from Luxury Bath Systems is what you're looking for. It's designed to nestle in a corner; so you don't need to build return walls beside it. And it can fit into a space barely 3 1/2 feet square, so it's ideal for converting a closet into a shower. As with all the products we make, sell and install, our neo-angle showers are made of durable, multi-layer Luxsan acrylic, infused with Microban® antimicrobial protection, and will look beautiful for years to come.
