Cost of adding a bathroom — Boston, MA

Last updated: September 24, 2026

What affects the price

Remodeling costs vary based on your specific goals. Choosing high-end materials like natural stone, custom cabinetry, or designer hardware will increase the total. Labor costs fluctuate depending on whether you are simply updating fixtures or doing a full layout overhaul that requires moving plumbing and electrical lines. Keeping your existing footprint is the most effective way to save, while expanding the space or adding luxury features like steam showers pushes the budget higher.
