What is the minimum distance plumbing fixtures should be positioned from a wall?

The minimum distance plumbing fixtures should be positioned from a wall is indeed 150 mm. This standard is designed to ensure adequate space for both accessibility and maintenance needs. By adhering to this distance, you allow enough room for the installation and servicing of fixtures, as well as ensuring that users can comfortably use the fixtures without feeling cramped or restricted.

This distance is particularly critical for fixtures such as toilets and sinks, where proper spacing contributes to the overall usability of the bathroom or kitchen space. Furthermore, this requirement helps in preventing damage to the plumbing system, as fixtures installed too close to walls may be subject to wear from constant use and make it challenging for future repairs or replacements.

A distance of 150 mm strikes a balance between optimizing space within a given area while maintaining safety and functionality standards set forth in the plumbing code.
