[Description] One-piece showers differ from modular or multi-piece showers in that they are composed of a single piece rather than several sections (base and wall panels). [Features] 
Installing a one-piece shower may be more difficult than installing a modular shower, especially in a tight space, because no cutting or adjusting is possible. If the shower is for an alcove, the dimensions must be exactly right.
