“Niche shelves are the detail that separates a remodel from a renovation. Built-in niches cost $150–$300 each in labor and material. They eliminate shower caddies, add visual depth, and signal quality to every person who uses the space. I specify at least two niches in every shower we build.”
Confirm your hot water heater location relative to the new bathroom. If the heater is more than 30 feet of pipe away, specify a recirculation pump ($400–600) that provides hot water at the fixture within seconds rather than waiting 45–90 seconds for the line to heat up. This is a detail most contractors don't proactively suggest.
