NYS and NYC M/WBE Certified Contractor
Most Centre Island homeowners aren’t dealing with a bathroom that’s broken — they’re dealing with one that just doesn’t belong anymore. The rest of the home has been updated, the views are incredible, and then you walk into a bathroom with 1980s tile and a builder vanity that looks like it came out of a tract house in Levittown. That gap matters. It shows up in how the space feels to live in, and it shows up in what buyers think when they walk through.
When the bathroom is done right — natural stone, a shower that actually works, fixtures that hold up — you stop noticing it in a bad way and start appreciating it in a good one. For a waterfront estate on Centre Island, that’s not a small thing.
There’s also a practical side that’s specific to this community. Homes here sit surrounded by saltwater on three sides — Cold Spring Harbor to the west, Oyster Bay Harbor to the east, Long Island Sound to the north. That marine environment is hard on bathrooms. Salt air breaks down caulk, corrodes fixtures, and accelerates grout failure faster than most contractors account for. A renovation done with the right materials and the right waterproofing behind the tile will hold up for decades here. One done without that attention won’t.
We serve Nassau and Suffolk Counties, and the North Shore communities in the Town of Oyster Bay — Centre Island, Cove Neck, Mill Neck, Bayville — are a regular part of that work. These aren’t standard suburban jobs, and we don’t treat them that way.
The homes here are architecturally significant, often historically layered, and worth serious money. Many have private septic systems instead of municipal sewer, plumbing configurations that predate modern layouts, and bathrooms that haven’t been touched in decades. We know how to work inside that reality — coordinating with the Town of Oyster Bay Building Division on permits, flagging septic compatibility before work starts, and sourcing materials that belong in a home at this level.
We’re a Long Island company. Not a franchise. Not a call center that dispatches a crew. When you reach out, you’re talking to people who know Centre Island and have worked in it.
It starts with a conversation, not a sales pitch. We come out, look at the space, understand what you’re trying to accomplish, and give you an honest read on what it involves — scope, timeline, and what permits will be required. For bathroom renovations in Centre Island, that means working through the Town of Oyster Bay Building Division, and for any project that touches plumbing, we evaluate compatibility with your existing septic system before anything else gets planned.
Once scope is agreed on and the permit process is underway, we build a project schedule that works around your life. Centre Island is a private community with one road in and one road out. We coordinate deliveries, dumpster placement, and crew scheduling in advance — no chaotic job sites, no unnecessary vehicles, no disruption to the neighborhood.
From there, it’s execution. Tile setting, plumbing, electrical, carpentry, glass — we manage all of it under one contract. You’re not tracking down separate subcontractors or resolving issues between trades. We handle the coordination, keep you updated throughout, and don’t consider the job done until the final walkthrough is exactly what was agreed on.

A bathroom renovation on a Centre Island estate can mean a lot of different things. It might be a full gut of a primary suite — new layout, steam shower, soaking tub, heated floors, custom stone throughout. It might be a guest bath that needs to be brought up to the standard of the rest of the house before a sale. It might be an aging-in-place upgrade — a walk-in shower replacing a tub, comfort-height fixtures, grab bars integrated into the tile design so they don’t look institutional. We handle all of it.
Every project in this community gets material specifications chosen with the coastal environment in mind. That means corrosion-resistant fixtures, waterproof membrane systems behind tile, marine-grade sealants, and ventilation that actively manages moisture — not just meets code. With homes sitting at the edge of Oyster Bay Harbor and Long Island Sound, those details aren’t optional.
We also work with homeowners who are coordinating with interior designers or architects on broader renovation projects. If you have a design direction already established, we build to it. If you’re starting from scratch, we can help you get there. Either way, the process is the same: clear scope, written contract, one accountable team from start to finish.
For most bathroom renovations in Centre Island, yes — a permit is required. The Town of Oyster Bay Building Division handles permitting for all residential construction in the village, and any work that involves moving plumbing, adding electrical circuits, or altering walls falls under that requirement. Purely cosmetic updates — swapping out a light fixture, replacing a mirror, painting — generally don’t trigger a permit. But if you’re doing a real renovation, you’re almost certainly in permit territory.
The process runs through the Oyster Bay Building Division at 74 Audrey Avenue. We handle the permit application and coordinate inspections as part of every project — you don’t need to manage that paperwork yourself. We build the permit timeline into the project schedule from the start so it doesn’t become a delay mid-renovation.
It’s a real factor, and it’s one that a lot of contractors underestimate. Centre Island is surrounded by saltwater — Cold Spring Harbor, Oyster Bay Harbor, and Long Island Sound — and the persistent marine humidity that comes with that environment is hard on bathrooms. Chrome and nickel fixtures corrode faster. Caulk and grout break down sooner. Moisture finds its way into places it shouldn’t if the waterproofing behind the tile isn’t done properly.
The fix isn’t complicated, but it requires intentional material selection. We specify corrosion-resistant fixtures, use waterproof membrane systems behind all tile work, and choose sealants rated for high-humidity coastal environments. Ventilation matters too — a bathroom fan that barely meets code isn’t enough when you’re dealing with the kind of ambient moisture that comes off the water year-round. Done right, a bathroom in Centre Island should hold up for decades without the failures you’d see from a contractor who treated it like any other Nassau County job.
It’s one of the first things we look at. Most properties on Centre Island use private septic systems — cesspools or modern septic — rather than municipal sewer, and any renovation that adds fixtures, increases water flow, or changes drainage routing needs to be evaluated for compatibility with what’s already in the ground. If you’re adding a second showerhead, a soaking tub, or a new toilet, those changes affect the load on your system.
We flag this before any work is planned, not after. If there’s a concern about capacity or compatibility, we address it at the design stage so it doesn’t become a problem — or an expensive surprise — after demolition has already started. For waterfront properties that may also have DEC-related restrictions on the building envelope, we factor that into the planning process as well.
For a full gut renovation — new tile, new plumbing fixtures, new vanity, shower, and all associated electrical — you’re typically looking at three to five weeks of active construction, depending on the scope and the complexity of the space. That timeline doesn’t include the permitting phase, which runs concurrently with design and material selection and typically adds two to four weeks on the front end for projects in the Town of Oyster Bay.
For larger, multi-bathroom estate projects, the timeline extends accordingly. We build a detailed project schedule before work starts and share it with you upfront — so you know what’s happening week by week and can plan around it. For homeowners who use their Centre Island property seasonally, we can often structure the project to be completed during the off-season, minimizing disruption to your time on the island during the months you’re most likely to be there.
It depends heavily on scope, but for a full primary bathroom renovation in a Centre Island home — custom tile, a walk-in shower, a freestanding or built-in soaking tub, custom vanity, and quality fixtures — you’re realistically looking at $40,000 to $80,000 or more depending on material selections and the complexity of the existing plumbing layout. Smaller guest bathroom renovations with high-quality finishes typically run $15,000 to $35,000.
In a community where homes are valued from $800,000 on the low end to well into the millions for waterfront estates, the cost of a quality bathroom renovation is proportional to what the property demands. Cutting corners on materials or waterproofing in a coastal environment isn’t a savings — it’s a deferred expense that shows up as failures within a few years. We give you a detailed written proposal before any work begins so the number is clear and there are no surprises once the project is underway.
Ask directly — and pay attention to the specifics of the answer. A contractor who has worked on North Shore estate homes in the Town of Oyster Bay will know things that a contractor who hasn’t simply won’t. They’ll know that most Centre Island properties run on private septic. They’ll know the Town of Oyster Bay Building Division’s permit process. They’ll know that the single road into the village requires advance coordination for deliveries and dumpsters. They’ll know that salt air off the harbor is a real material consideration, not a talking point.
Beyond that, ask to see work from comparable projects — high-value homes with premium finishes, ideally in coastal or waterfront settings. Ask about their licensing under the Nassau County Office of Consumer Affairs. Ask who manages the project day to day and how they handle communication when something unexpected comes up. In a community as private and as specific as Centre Island, the right contractor is one who treats your home with the same level of attention you’d expect from any other professional you bring onto an estate property.
