What is the minimum horizontal distance required between two adjacent shower heads in a battery installation (except column showers)?

In a battery installation for shower heads, the minimum horizontal distance required between two adjacent shower heads is established as 750 mm. This requirement is primarily concerned with providing sufficient space for users to shower comfortably without interference from adjacent showers. It also ensures water spray from one shower head does not directly impact another, which helps maintain a comfortable and hygienic showering environment.

The specification of 750 mm balances the need for efficient use of space in residential and commercial settings with the practicality of showering experiences. This standard is designed to promote safety and usability while minimizing the risk of water cross-contamination between adjacent shower heads.

While other distances might be considered for different types of installations or specific scenarios, the 750 mm distance is codified to suit typical usage patterns and configurations found in many plumbing codes, reflecting a consensus based on ergonomics and convenience in modern plumbing practices.
