Key Differences

A step is a single section of a staircase that you place your foot on when ascending or descending. On the other hand, stairs refer to a complete set of steps that collectively make up a stairway, allowing people to move from one level to another.
In construction and architecture, the design of a step focuses on its depth, height, and tread, tailored to ensure safety and comfort in foot traffic. Whereas, the design of stairs encompasses not only the individual steps but also elements like handrails, landings, and balusters, which contribute to the overall functionality and safety of the stairway.
Typically, the term "step" can also metaphorically represent a phase or stage in a process, illustrating progression or a change in state. Meanwhile, "stairs" rarely see such metaphorical use, being more concrete in their reference to physical structures.
When it comes to maintenance and discussion in home improvement, you might consider the repair or replacement of a damaged step. On the other hand, discussions about stairs usually involve considerations of the entire staircase, which might include upgrading or modifying the stairwell for better access or aesthetic appeal.
While a step could be part of various environments, including outdoor landscapes or machines, and isn't limited to staircases, stairs specifically denote the collective assembly within buildings or structures dedicated to bridging vertical distances.
