For most homeowners, the planning and design of a bathroom can be an exciting-but daunting-prospect. Whether you are renovating an existing space, or starting with bare-bones construction, you should essentially use the same guidelines for planning the room that reporters use for writing a story: who, what, where, and how.
Who may seem pretty basic when it comes to a bathroom, but the answer can make a big impact on design plans. A guest bathroom that is used only occasionally is probably going to be a lot different than one that is primarily used by children on a daily basis.
Once you’ve discovered who, move on to the where. That’s generally an easy one to solve. In new construction, the master bath will be adjacent to the master bedroom, the children’s bathroom will be located near their bedrooms, etc. In existing homes, you will probably leave the room where it is.
