As of 2015, Kohler.com gives over 100 layout designs with square footage and length and width of the bathroom. These layouts are good for homes that are built with typical dimensions that most builders use. This website, however, does not give dimensions for bathtubs or showers, toilets or vanities, as they assume buyers use standard utilities.

Each category gives tips and pros and cons about the size and layout of each bathroom and the best way to utilize the space. Again, this website does not give dimensions for typical furnishings.
