How big should a two person shower be?

A two-person shower should ideally be at least 5 feet by 3 feet (about 60 by 36 inches) to provide enough space for both individuals to move comfortably. A larger size, such as 6 feet by 4 feet, offers more room for added features like benches or multiple showerheads. Additionally, consider the layout and any fixtures to ensure a pleasant experience without feeling cramped.
