Price of concealed electrical box

A concealed electrical box typically costs between $3 and $25 per unit, with total installation costs ranging from $150 to $500 or more depending on materials and labor.Material and Unit CostsConcealed electrical boxes can be made from plastic (ABS or PVC) or metal (galvanized steel or aluminum). Plastic boxes are generally cheaper but less durable, while metal boxes offer better safety, corrosion resistance, and structural integrity, especially in moisture-prone areas like kitchens or bathrooms . For example, a bulk-purchased 86-type galvanized steel concealed switch box can cost around $3.20 per unit, whereas standard plastic units may be slightly less expensive . Specialized boxes for heavier loads or masonry installation can cost $11 to over $25 per unit .Installation CostsThe labor cost is a significant factor in concealed box installation. Retrofitting a box into existing walls requires careful cutting, wiring, and patching, which is more time-consuming than installing in new construction . Licensed electricians typically charge $40 to $130 per hour, with minimum service fees of $150 to $200. Overall, homeowners can expect total installation costs, including materials and labor, to range from $150 to $500 for a standard concealed box installation .Factors Affecting CostBox size and depth: Larger or deeper boxes for multiple wires or GFCI outlets cost more .Material quality: Galvanized steel or heavy-duty aluminum boxes are more expensive but safer and longer-lasting .Installation complexity: Retrofitting into finished walls, working in tight spaces, or adding extra support brackets increases labor costs .Permits and inspections: Some jurisdictions require permits, typically costing $50 to $200, which adds to the total project cost .SummaryWhile the unit cost of a concealed electrical box is relatively low, the total project cost is heavily influenced by labor, installation complexity, and material choice. Investing in a durable metal box is often worthwhile for safety and longevity, particularly in older homes or high-use areas .
