We transform utilitarian bathrooms into private spa-grade sanctuaries using radiant heated flooring, seamless curbless glass, and meticulously sourced fixtures. This is not a remodel — it is a daily retreat built exactly to your physiology and preferences, using materials that improve with age and craftsmanship that holds for generations.
Every bathroom project begins with a detailed waterproofing and structural plan. We engineer curbless shower transitions, heated floor systems, and steam generator installations before a single tile is selected, ensuring that the technical infrastructure supports the aesthetic vision — not the other way around.
ConstruBay (CSLB #1106798) is based in Mill Valley and has executed luxury bathroom remodeling projects across Marin, Sonoma, and Napa Counties.
What Is Included
The Marin Advantage
Bathroom remodels in Marin County require precise permit management, particularly for projects involving gas steam generators, electrical panel modifications, or structural alterations. Our team has completed luxury bathroom renovations across Mill Valley, Tiburon, Belvedere, Ross, and Kentfield, navigating the specific inspection requirements of each jurisdiction. Our PlanPass.ai system pre-verifies permit packages before submission, and our relationships with local inspectors ensure smooth, timely final approvals. We are deeply familiar with the seismic anchoring requirements for freestanding fixtures and heavy stone installations common in Marin's hillside estates.
