Sabana Grande Abajo is located in the southwestern municipality of San Germán, positioned in the lower portion of the barrio's namesake area. The barrio sits within the broader Lajas Valley region, characterized by relatively flat to gently rolling terrain typical of southwestern Puerto Rico's agricultural and rural zones. This geographic setting distinguishes it from the more mountainous interior regions further east, making it part of a landscape historically suited to farming and cattle ranching.

The barrio spans approximately 7.82 square kilometers and maintains a predominantly rural character. Properties in Sabana Grande Abajo tend toward larger parcels and agricultural land rather than dense urban subdivision. The landscape is a mix of working agricultural properties, scattered residential holdings, and undeveloped acreage. This rural composition reflects the historical land-use patterns of the San Germán area, where traditional farming operations and family-owned properties have long been the norm. Owners and prospective buyers in this barrio typically seek land for agricultural purposes, residential development on larger lots, or long-term property holdings in a quieter, less developed setting compared to San Germán's urban core.
