Entertainment center & media room cost calculator

Most built-in entertainment centers cost $2,000 to $18,000 installed in 2026. A floating media console runs about $1,500–$7,500. A TV wall unit with base cabinets and shelving towers runs $2,000–$18,000. A floor-to-ceiling custom media wall runs $7,000–$35,000+.

Cabinet tier (ready-to-assemble, semi-custom, or custom), wall width, ceiling height, and finish are the biggest drivers. TVs and audio are extra.

Plan on roughly $150–$300 per linear foot for ready-to-assemble built-in hacks, $350–$650 for semi-custom, $650–$1,100 for custom paint-grade, and $1,100–$2,000+ for premium stain-grade walnut or white oak. These are full-height, installed prices for an 8 ft ceiling. Taller ceilings add about 12% per foot.

A media room usually costs $15,000–$60,000 all in for a 250–400 sq ft space. That covers a media wall, a TV, a soundbar or 5.1 system, dimmable lighting, paint, and carpet. Building the room out from bare studs or an unfinished basement adds framing, insulation, drywall, and HVAC, typically $35–$75 per sq ft before AV.

A dedicated home theater typically costs $50,000–$150,000+. Construction with sound isolation, risers, and acoustic treatment runs about $90–$175 per sq ft. On top of that, a 7.2.4 Dolby Atmos system is about $8,000–$18,000, a projector and screen $4,000–$12,000, and theater seating $3,500–$12,000. Reference-grade systems from Trinnov, JBL Synthesis, or Triad can exceed $75,000 for the AV alone.

Professional TV mounting with an in-wall recessed power and HDMI kit typically costs $350–$800 including the mount. If you need a new dedicated outlet, a licensed electrician and a permit bring that to $800–$1,800. Running an ordinary power cord inside the wall violates the National Electrical Code, so use a rated recessed kit or a new outlet behind the TV.

A fireplace media wall with built-ins on both sides, a finished surround, and a TV above typically costs $8,000–$30,000+. A linear electric fireplace insert from Dimplex, Napoleon, or Modern Flames adds $1,800–$5,500 installed. A pull-down mount such as MantelMount ($900–$2,200) brings the TV down to a comfortable viewing height.

It can be. IKEA boxes keep material costs low, and a carpenter who adds filler panels, a toe kick, crown molding, scribing, and paint can make them look built in for about $150–$300 per linear foot. The trade-offs are particleboard construction, fixed sizes that leave gaps on odd walls, and a finish that won’t match a painted custom wall up close.

Base cabinets are usually 16–24 inches deep. AV receivers need about 20 inches plus airflow. Upper shelving is typically 12–16 inches. A recessed TV niche needs only 4–6 inches beyond the mount depth, while a false wall built to hide wiring or an electric fireplace insert is usually 12–18 inches deep.

Cabinetry and low-voltage wiring usually don’t need a permit. A new electrical circuit or outlet generally does, and so does framing new walls, finishing a basement, or changing HVAC for a theater. Permit fees vary by jurisdiction, from about $75 for a simple electrical permit to several hundred dollars for a room build-out.

Well-built built-ins help a living room or finished basement show better and tend to appeal to buyers, but don’t expect a dollar-for-dollar return. Painted, timeless cabinetry holds its appeal far longer than a niche sized for one particular TV, so keep the TV opening flexible and wire the wall with conduit for future upgrades.

Installing a ready-to-assemble or semi-custom unit usually takes one to three days. Fully custom built-ins take two to six weeks from design approval, depending on shop lead times, plus one to three days on site for installation and finish. A full media room or theater build-out usually takes four to ten weeks.
