NYS and NYC M/WBE Certified Contractor
Great Neck sits on a peninsula surrounded by Long Island Sound and Manhasset Bay. That’s not just a scenic detail — it means your home deals with elevated humidity year-round, and bathrooms that weren’t built or renovated with that in mind tend to show it. Grout cracks, caulk fails, tiles loosen, and moisture works its way behind walls before you ever see the damage. We account for that from the start, not as an afterthought.
Beyond the moisture factor, a lot of the homes here were built in the 1920s through the 1950s — gorgeous architecture, but original plumbing and waterproofing that was never designed to last this long. When you renovate, you’re not just updating the look. You’re replacing what’s been quietly degrading behind the walls for decades. Done correctly, that’s the kind of work that protects the value of a home in a market where prices have climbed more than 77% over the past ten years.
For the long-term homeowners on the peninsula — the ones who’ve been in their homes for 20 or 30 years and plan to stay — a well-designed bathroom remodel can do both jobs at once. It can look like a luxury spa and function like a space that works for you as your needs change, without looking like a medical retrofit.
Green Island Group is a full-service bathroom remodeling contractor serving Nassau County, including the Great Neck peninsula and the surrounding North Shore communities. We work across all nine of Great Neck’s incorporated villages — each with its own building department — and we know how to navigate that process without putting the burden on you.
What that means practically: we pull the right permits, coordinate with the right inspectors, and make sure your renovation closes out with a Certificate of Occupancy. In a market where buyers scrutinize every detail and home values are this high, that paper trail matters. An unpermitted bathroom in a $1.2 million home is a problem waiting to surface at closing.
We’ve worked in the older colonials and Tudors that line the streets near Great Neck Plaza, the larger homes in Kings Point, and everything in between. The housing stock here has specific characteristics — original framing, aging supply lines, older waterproofing — and we know how to work with it, not around it.
It starts with a walkthrough of your existing bathroom. We’re looking at what’s there, what’s behind it, and what the renovation actually requires — not just what it looks like on the surface. In older Great Neck homes, that first look often reveals things that need to be addressed before the design work even begins: corroded supply lines, failing waterproofing, or moisture damage that’s been sitting behind original tile for years. You’ll know about all of it upfront, with a fully itemized written estimate before any work starts.
Once the scope is clear and you’ve approved the plan, we handle the permit application with the appropriate village building department — whether that’s the Village of Great Neck, Great Neck Estates, Kings Point, or any of the other incorporated villages on the peninsula. Construction follows a defined schedule, Monday through Friday with Saturday availability where the project requires it. Our own crews do the work — not subcontractors we called the week before your job started.
When the work is done, we coordinate the final inspection and make sure you receive your Certificate of Occupancy. That’s not a bonus step — it’s part of the job. In Nassau County, all bathroom remodeling work requires a permit, and the sign-off at the end is what makes the renovation real on paper.

A bathroom remodel with us covers the full scope — demo, plumbing rough-in, waterproofing, tile, fixtures, vanity, lighting, and finish work. Nothing is handed off mid-project. The same crew that starts your job sees it through to the final inspection.
For Great Neck homes specifically, we build in the waterproofing that coastal humidity demands. We use commercial-grade moisture barriers, mold-resistant cement board, and ventilation systems that are matched to the actual conditions of a North Shore Long Island home — not a standard spec that was written for somewhere drier. If your home is one of the older colonials near Middle Neck Road or a larger property in Kings Point, we also know how to work around original framing and older infrastructure without turning a bathroom renovation into a whole-house project.
On the finish side, we work with large-format porcelain and natural stone tile, frameless glass enclosures, custom vanity cabinetry, and plumbing fixtures from brands that belong in a home at this price point. We also design and build aging-in-place features — no-threshold walk-in showers, comfort-height toilets, grab bars that look intentional rather than institutional — for homeowners who want a bathroom that works beautifully now and stays functional long-term. Whatever the scope, the standard stays the same.
Yes — Nassau County requires a building permit for all bathroom remodeling work, regardless of the scope of the project. That applies whether you’re doing a full gut renovation or a more targeted update. What makes Great Neck specific is that the permit authority depends on which of the nine incorporated villages your property is in. The Village of Great Neck, Kings Point, Great Neck Estates, Kensington, and the other villages on the peninsula each have their own building department, and the application goes to the right one based on your address.
We manage the entire permit process on your behalf — application, coordination with the building department, inspections during construction, and the Certificate of Occupancy at the end. You don’t need to figure out which village department to call or what forms to submit. We handle it. And in a market where homes regularly sell for well over a million dollars, having a properly permitted renovation on record protects you when it’s time to sell.
The range is wide, and it depends on the size of the bathroom, the condition of what’s behind the walls, and the finish level you’re going for. A guest bath update in a Great Neck home — new tile, fixtures, vanity, and updated plumbing — typically runs in the $25,000 to $40,000 range. A full master bath renovation with custom tilework, a frameless glass enclosure, a freestanding soaking tub, and high-end fixtures can run $75,000 to $150,000 or more depending on materials and scope.
One thing worth knowing for Great Neck specifically: older homes on the peninsula frequently have conditions behind the walls — aging supply lines, failing waterproofing, moisture damage — that aren’t visible until demo begins. We address all of that in the initial walkthrough and give you a fully itemized estimate before work starts, so you’re not hit with surprises mid-project. The estimate reflects the actual job, not an optimistic version of it.
For a standard bathroom remodel, plan on two to three weeks of active construction once permits are approved and materials are on-site. A larger master bath renovation — especially in an older home where the scope expands after demo — can run four to six weeks. The permit timeline in Nassau County’s incorporated villages adds time upfront, which is why starting the process early matters if you have a target completion date in mind.
For Great Neck homeowners who commute into the city via the LIRR, the schedule is something we take seriously. We work Monday through Friday and Saturday where needed, and we’re clear about daily progress so you’re not coming home to uncertainty. If you’re planning a renovation around a specific event or a home sale, tell us that at the start — it helps us sequence the work and set a realistic timeline from the beginning.
The first thing to confirm is licensing and insurance. In Nassau County, contractors must be licensed with the county and the Town of North Hempstead to legally perform remodeling work. Ask for proof of both general liability insurance and workers’ compensation coverage before anyone sets foot in your home. In a high-value market like Great Neck, hiring an unlicensed contractor isn’t just a quality risk — it’s a legal and financial one.
Beyond credentials, ask specifically about permit management. A contractor who tells you permits aren’t necessary for your project, or who suggests you pull the permit yourself, is a red flag. All bathroom remodeling work in Nassau County requires a permit. Also ask whether the contractor uses its own crews or subcontracts the work. In a community where word-of-mouth travels — from Kings Point to Russell Gardens to Great Neck Estates — the contractors who last are the ones who stay accountable from start to finish, not just through the sales process.
Absolutely, and this is something a lot of Great Neck homeowners are thinking about. The peninsula has a significant population of long-term residents — people who’ve been in their homes for decades and want to stay. The goal is a bathroom that functions well as needs change without looking like it was designed around a medical checklist.
The features that matter most — no-threshold walk-in showers, comfort-height toilets, grab bars, non-slip tile — can all be integrated into a high-end design without drawing attention to themselves. A grab bar in brushed nickel that matches your fixtures reads as a design choice, not an accommodation. A curbless shower with large-format stone tile looks like a luxury spa, not a safety retrofit. We design these features to work with the aesthetic of the bathroom, not against it — which matters in a home where the overall design standard is already high.
Yes — we work throughout the Great Neck peninsula, including all nine incorporated villages: the Village of Great Neck, Kings Point, Great Neck Estates, Great Neck Plaza, Kensington, Russell Gardens, Thomaston, Saddle Rock, and University Gardens, as well as the unincorporated areas on the peninsula. Each village has its own building department, and we’re familiar with the permitting requirements across all of them.
We also serve the surrounding North Shore communities — Manhasset, Port Washington, Roslyn, Lake Success, and North Hills — so if you have family or neighbors in those areas who are looking for a bathroom remodel contractor, we’re already working in those communities. The Nassau County North Shore is our home market, and that familiarity with the local housing stock, the permit landscape, and the standards homeowners here expect is something we bring to every project we take on.
