An arid desert climate will influence floor finish selections with respect to wear and soilage. For example, in dry sandy areas, carpeting may not be a desired floor finish for certain spaces. In these cases, hard surfaces such as tile may be much more appropriate and easier to maintain. As a result, other finish and furniture selections must be more critically chosen to achieve the same level of ambiance.

More cost effective and available materials in one area may be considered more a luxury item in other areas.
