The answer to 'P-trap installation cost' is that the typical range for a basic P-trap installation by a professional plumber is $75 to $300, depending on several factors. The cost can vary based on the complexity of the job, the materials needed, the plumber's hourly rate, and your location.
For a simple P-trap replacement in an accessible area, you're likely looking at the lower end of that range. However, if the P-trap is in a tight space, requires additional plumbing work, or needs specialized tools or materials, the cost can be closer to the higher end. Getting local quotes from licensed plumbers is essential to accurately estimate the cost for your specific project.
