What should be the height of the distance between the floor and the drain board in a kitchen sink after installation?

The correct height of the distance between the floor and the drain board in a kitchen sink after installation being 36 inches is based on standard plumbing practices which aim to ensure proper function and accessibility. This height is designed to provide a convenient working level for users, allowing them to use the sink comfortably while preventing issues related to drainage.

A height of 36 inches is effective for facilitating easy access to both the sink and the drain board. It allows for an appropriate slope for drainage which ensures that water flows away without pooling. This standard aligns with ergonomic principles, making it suitable for most users to operate the sink without strain.

Other height options, though potentially viable for specific situations, are not commonly implemented in standard kitchen designs. Heights that are significantly lower or higher might create obstacles in usage or lead to inefficient drainage practices, hence are not advisable.
