Bathroom remodeling built for Boulder housing stock
Boulder’s bathrooms come with their own set of problems. Older homes in Whittier, University Hill, and Mapleton Hill often still have galvanized supply lines, cast iron drains, and framing that’s out of square after a century of settling. Remodeling one of these bathrooms usually means re-piping, moving a vent stack, or building out a wall to get a tub or shower to fit modern fixtures. We plan for that upfront instead of finding out mid-demo.
Newer construction in neighborhoods like Gunbarrel or South Boulder has its own quirks, including tight mechanical chases and builder-grade fiberglass units that don’t hold up to Boulder’s dry climate and hard water. We size ventilation correctly for our elevation and humidity swings, and we spec fixtures and grout that actually survive the mineral content in Boulder’s water supply.
Permits, HOAs, and Boulder's review process
Most bathroom remodeling projects in Boulder require a building permit through the city’s Planning and Development Services office, especially once you’re moving plumbing fixtures, altering wall framing, or touching electrical circuits. A simple fixture swap may not need one, but relocating a shower drain or expanding a bathroom’s footprint does. We pull these permits ourselves and schedule inspections so you’re not stuck managing paperwork or chasing an inspector’s availability.
If your property sits in a historic district like Mapleton Hill or Whittier, or falls under an HOA in a planned community such as parts of Gunbarrel, exterior changes or any work affecting a shared wall can trigger an added layer of design review. We handle that coordination as part of the job, not as a change order surprise later. Many of our Boulder bathroom clients are also updating their kitchens around the same time, and our kitchen remodeling in Boulder work follows the same fixed-scope approach.
