The national average to remodel a small bathroom is typically $6,500, but it can range anywhere from $1,500 up to $15,000 or more. For a complete remodel, you will likely pay $70 per square foot for low-end fixtures with DIY labor, and up to $250 per square foot for high-end fixtures installed by a licensed contractor. Labor can also vary depending on your location - a contractor in Cedar Rapids, IA will charge a fraction of what you'd be billed in Manhattan.
