Bathroom remodeling built for Tiburon homes
A bathroom remodel in Tiburon is never just a bathroom. On these hillsides and along Belvedere Cove, the rooms that matter most are the ones framing the water, and a primary bath cantilevered over the slope deserves the same intent as the view it looks out on. New Key Construction is a Marin design-build firm that handles design and construction under one roof, so the people who draw your new bath are the same people who build it. You get priced options up front, photoreal 3D renderings before any permit is pulled, and white-glove project management from demolition to the final fixture.
Tiburon's housing stock is unusually varied for a town its size. Old Town near Main Street holds compact cottages with narrow footprints and tight plumbing chases. The hillsides above carry mid-century post-and-beam houses and glass-wrapped modernist homes with open plans and large window walls. Newer contemporary and contemporary-coastal builds push clean lines and spa-grade baths. Each of these calls for a different remodeling approach, and a wet wall that works in a 1960s post-and-beam will not behave the same way in an Old Town cottage. We design to the house in front of us, not to a template.
One team, priced options, renderings before permits
Most bathroom projects go sideways at the seam between the designer and the contractor, where a beautiful drawing meets a stud bay that cannot hold it. Because we carry design and build together, that seam disappears. Before we touch a wall, we model your new bath in 3D so you can see the stone, the vanity, the glass, and the light exactly as they will land. We attach real numbers to real options, so the choice between a curbless walk-in shower and a freestanding soaking tub is a decision you make with a price next to it, not a surprise you absorb later.
That clarity matters more in Tiburon than in most places, because the path to a permit here has its own rhythm. The Town of Tiburon runs its own Planning Division and Building Department, separate from unincorporated Marin County, and exterior changes in town frequently trigger Design Review through the Planning Division before a building permit is issued. An interior bathroom remodel that stays inside the existing walls often moves faster, but the moment you add or enlarge a window for that bay view, change the roofline for a skylight, or alter the building's exterior on a hillside or near the shoreline, you can be looking at a Design Review track that adds weeks. We map that path at the start, prepare clean single-PDF submittals the way the town asks for them, and coordinate the pre-submittal conversation so your project does not stall at the counter.
What a Tiburon bathroom remodel involves
The scope depends on the house. In hillside modernist homes, the work often centers on a primary bath that wants to read like a continuation of the living space: large-format porcelain or natural stone, frameless glass, radiant floor heat against the marine air, and fixtures placed to keep the window wall clear. In Old Town cottages, the challenge is usually fit, rerouting aging plumbing and squeezing genuine luxury into a small, original footprint without losing the character that makes the home worth living in. Across both, our process is the same: survey the real conditions, model the design in 3D, price the options, secure the right approvals, then build with a single accountable team and a clean site.
Material choices on the Tiburon waterfront also have to respect the setting. Salt air and persistent humidity are hard on hardware, ventilation, and finishes, so we specify corrosion-resistant fixtures, real exhaust capacity, and waterproofing details built to last rather than to pass a quick inspection. The goal is a bathroom that still looks and performs beautifully after a decade of Bay weather.
Frequently Asked Questions
Do I need design review for a bathroom remodel in Tiburon?
If your remodel stays entirely inside the existing walls, you generally need a building permit but not Design Review. Design Review through the Town of Tiburon Planning Division is typically triggered by exterior changes, such as adding or enlarging a window, adding a skylight, or altering the building on a hillside or near the shoreline. We confirm which track applies before design begins so there are no surprises.
How long does a bathroom remodel take in Tiburon?
A straightforward interior bathroom remodel usually runs several weeks of construction once permits are in hand. If your project requires Design Review because it touches the exterior, plan for roughly two to four additional weeks on the approval side before construction starts. We build that timeline into the schedule up front so you know the full arc, not just the build.
Who pulls the permits, the town or the county?
Tiburon is an incorporated town with its own Planning Division and Building Department, so permits for properties inside town limits go through the Town of Tiburon rather than unincorporated Marin County. We handle the submittal, prepare plans as the single combined PDF the town requests, and coordinate the pre-submittal contact with the planning staff on your behalf.
Can you remodel a small Old Town or hillside bathroom without losing its character?
Yes. Old Town cottages and mid-century hillside homes often have tight footprints and original detailing worth keeping. We use the 3D model to test how a curbless shower, a repositioned vanity, or a rerouted plumbing chase fits the real space before any demolition, so you see the result and the price before we commit to it.
Why design-build instead of hiring a designer and a contractor separately?
With design-build, one team owns the outcome from concept through construction, which removes the gap where a design meets a wall that cannot hold it. You get priced options up front, photoreal renderings before permits, and a single point of accountability for the schedule, the budget, and the finished room.
