The cost of re-piping and moving a washer and dryer to a different room can vary significantly depending on various factors such as the location, the complexity of the plumbing and electrical work required, the distance of the new location from the existing plumbing and electrical connections, and the labor rates in your area. Additionally, any necessary modifications to the new room, such as adding or modifying water and drain lines, electrical outlets, and ventilation, will also impact the overall cost.
To get a more accurate estimate for your specific situation, it's best to consult with licensed plumbers and electricians who can assess the project requirements and provide you with a detailed quote. They may need to inspect your current setup and the new room to determine the extent of the work needed.
As a rough estimate, re-piping and moving a washer and dryer to a different room could cost anywhere from a few hundred to a few thousand dollars, depending on the complexity of the job and the regional pricing. It's essential to get multiple quotes from different contractors to ensure you're getting a fair price for the work.
