Southwest Desert Garden Bathroom Backsplash and shower inset tile mosaic. Hand cut and shaped tiles of saguaros, agaves, purple prickley pear and other desert cacti make this bathroom backsplash unique to Arizona Southwest Decor. Bright primary glazes add a brilliance of fun color to the decor. The design was drawn then cut out of clay, fired, glazed, fired and set by the artist. There is even a little yellow jeep tile on top of a cacti in the shower!
