AWARD WINNING: ANGIE’S LIST SUPER SERVICE AWARD (14 YEARS CONSECUTIVE)
A bathroom renovation is one of the most impactful investments a Long Island homeowner can make — both in terms of daily quality of life and measurable property value. Whether you are transforming a dated master bathroom into a spa-like retreat, updating a hall bath that has not been touched since the 1990s, or deciding between a full gut renovation and a targeted refresh, this guide gives you everything you need to plan and execute a successful bathroom renovation in Nassau or Suffolk County.
OZ General Contracting has been completing bathroom renovations across Long Island since 1976. This guide reflects real experience with real projects in Nassau and Suffolk County homes — not generic advice that could apply anywhere.
The bathroom — particularly the master bathroom — is among the rooms buyers scrutinise most carefully when evaluating a home purchase. A renovated master bathroom consistently ranks in the top three features that Long Island homebuyers cite as decision-influencing factors.
According to New York metro area Cost vs. Value data, a mid-range bathroom renovation returns approximately 60 to 70 cents on the dollar at resale, making it one of the highest-returning renovation investments available to Nassau County homeowners.
Beyond resale value, the daily quality-of-life impact of a well-designed bathroom is substantial. The bathroom is where most days begin and end. A space with heated floors, good lighting, ample storage, and materials that feel luxurious rather than institutional changes the experience of your home in ways that compound every single day you live there.
Long Island housing stock — with its strong inventory of post-war homes in Nassau and Suffolk County — includes a large number of bathrooms that have not had a substantive renovation in decades. These bathrooms represent enormous opportunity for transformation. A bathroom that was functional in 1985 can become genuinely beautiful in 2026 with the right renovation approach.
Bathroom renovation costs in Nassau County in 2026 vary significantly depending on the size of the bathroom, the scope of work, and the materials and fixtures selected:
New vanity, toilet, fixtures, updated lighting, fresh tile work. A focused update that dramatically improves a high-visibility room at a relatively modest investment.
Complete gut renovation — new tile throughout (floor and walls), custom vanity, updated plumbing fixtures, frameless mirror or medicine cabinet, recessed lighting, exhaust fan upgrade. The most common renovation scope for Nassau County hall baths and secondary bathrooms.
Full gut renovation with a large custom vanity (often double-sink), frameless glass walk-in shower, either a freestanding or built-in soaking tub, heated floor tile, custom tile work throughout, premium fixtures, built-in niches, and a comprehensive lighting plan.
Natural stone tile throughout, custom built-in cabinetry, multiple shower heads including rain head, steam shower feature, freestanding soaking tub, high-specification fixtures from Hansgrohe, Kohler, or Waterworks, heated towel bars, and a design that functions as a complete wellness retreat.
The four biggest cost drivers within each tier: bathroom square footage, tile selection (size, material, and pattern complexity), fixture brands, and whether plumbing is being relocated.
One of the most common questions we hear from Long Island homeowners is whether they need a full gut renovation or whether a targeted partial update will achieve their goals. The honest answer depends on the specific condition of your bathroom and what you want to achieve.
One important caveat: it is worth having a contractor assess the condition behind your existing tile before committing to a partial refresh. Nassau County homes built in the 1960s through 1980s sometimes have moisture damage behind tile that is not visible from the surface. A partial update that covers up moisture damage will not solve the problem — it will resurface within a few years. OZ General Contracting always assesses visible signs of underlying issues during the free consultation.
The quality of your bathroom renovation is determined more by the contractor you choose than by any other single factor. A beautiful tile design poorly installed will look bad within a year. A perfect vanity selection installed by a plumber who takes shortcuts will leak within months.
The essentials to verify before hiring any bathroom contractor in Nassau or Suffolk County:
Nassau County Licence verification: nassaucountyny.gov — Office of Consumer Affairs. OZ General Contracting Nassau County Licence: #184594.
General liability and workers compensation. Ask for a Certificate of Insurance and confirm it is current before work begins.
An A+ BBB rating maintained over many years reflects a consistent pattern of trustworthy business conduct. OZ General Contracting: BBB A+ since October 1991.
Angi, Google, and Houzz all publish verified reviews from customers who actually hired the contractor. Look specifically for mentions of tile work quality, timeline adherence, and how problems were handled when they arose.
Who is on your job site every day? The answer "our crew" is not good enough. You want a specific person — a project manager who is accountable for the daily progress and quality of your renovation. At OZ General Contracting, Mike Ovadia is on every job site every day.
Any estimate that does not break down tile, labour, fixtures, vanity, plumbing, and permits as separate line items is not giving you the information you need to make a sound decision.
Bathroom design in Nassau and Suffolk County homes reflects the broader shift toward materials and aesthetics that feel personal, warm, and spa-like rather than clinical and white. Based on our current project pipeline, these are the styles generating the most enthusiasm:
The most requested design direction for master bathroom renovations across Long Island. Characterised by large-format natural stone or stone-look tile (often 24×48 or 24×24), a frameless glass walk-in shower with a rain-head and linear drain, a freestanding soaking tub as a focal point, warm wood-toned vanity cabinetry, heated floors, and a lighting plan that shifts between bright task lighting and warm ambient lighting. The goal is a room that functions as a daily wellness space.
Clean lines, minimal hardware, and a palette that bridges traditional and contemporary. Typically features a floating double vanity in a warm grey or white, large-format tile in a subtle pattern, frameless glass shower enclosure, and fixtures in matte black or brushed nickel. Popular across a wide range of Nassau County home styles.
Timeless and increasingly popular as a counter-reaction to the all-grey bathrooms of the 2010s. Black matte fixtures, white subway or bevelled tile, black hexagonal floor tile, a white vanity with black hardware, and a frameless mirror. Looks equally at home in a 1950s Cape and a contemporary build.
Terracotta, warm beige, sage green, and soft brown tones replacing the cool greys that dominated the previous decade. Zellige or handmade tile in warm tones, natural wood vanity cabinetry (or wood-look finishes), unlacquered brass or brushed gold fixtures, and organic shapes. This direction is especially popular in master bathrooms in Massapequa, Syosset, and Rockville Centre homes.
Many Nassau County homes have secondary bathrooms under 50 square feet. OZ General Contracting has completed hundreds of small bathroom renovations, and our in-house CNC manufacturing is particularly valuable here — we can build a vanity to fit a 28-inch space, create a recessed medicine cabinet that adds storage without taking up floor space, and design a shower niche that uses every available inch. Small bathrooms in Long Island homes can be genuinely beautiful with the right design approach.
Tile is the dominant material in any bathroom renovation and the selection that most determines the finished aesthetic. Current preferences in Nassau County bathroom renovations:
At OZ General Contracting, all bathroom vanities are manufactured in our Bellmore CNC facility to the exact dimensions of your bathroom. This means we can build a 31-inch vanity for a bathroom where a standard 30 or 36-inch piece does not fit, create a floating vanity at any height, or design a double vanity with integrated storage that uses every available inch. Custom-built vanities transform bathrooms where standard off-the-shelf pieces would always feel like a compromise.
The standard for any master bathroom or primary bathroom renovation in Nassau County. Frameless glass (as opposed to framed or semi-frameless) makes a bathroom feel dramatically larger, shows off tile work without interruption, and is significantly easier to keep clean. We work with trusted glass fabricators across Long Island who produce custom-measured frameless enclosures for every shower configuration.
Electric radiant floor heating beneath tile is one of the most consistently loved upgrades our Long Island clients ever invest in. The system is a thin heating cable or mat installed on the subfloor before tile is set, controlled by a programmable thermostat. Warm floors every morning before you get up — particularly valued during Long Island winters. Most efficiently installed during a full gut renovation when the subfloor is already exposed. We install Nuheat and Warmup systems regularly.
Bathroom lighting is one of the most frequently underestimated elements of a renovation. A well-designed bathroom lighting plan typically includes: bright, even task lighting at the vanity mirror (ideally on both sides of the mirror, not just above it, to eliminate face shadows), recessed ceiling lighting for general illumination, and a separate dimmer circuit for ambient lighting that creates the warm, relaxing atmosphere of a spa-style bathroom. We design lighting plans as part of every bathroom renovation — not as an afterthought.
Most bathroom renovations in Nassau County require permits, and understanding the rules before you start prevents expensive complications later.
Work that requires a permit:
Work that generally does not require a permit:
Unpermitted plumbing or electrical work in a bathroom is a significant issue when selling a Long Island home. Buyers inspectors are experienced at identifying work that was done without permits, and unpermitted work can result in required remediation before closing, price reductions, or lost sales.
We manage the entire permit process — applications, county coordination, and all required inspections — as part of our full-service renovation. Permit fees are included in your written estimate. You do not need to deal with the Nassau County Building Department or your local village building department yourself.
Uzi Ovadia visits your home and assesses your bathroom honestly. He identifies any signs of moisture damage, structural issues, or plumbing configurations that will affect the renovation approach. He discusses your vision, your budget, and your timeline openly. There is no sales pressure.
Our Design Consultant Lori guides you through every tile selection, vanity finish, fixture choice, glass specification, and lighting plan. She produces 3D renderings of your finished bathroom — you see exactly what you are getting before a single tile is ordered. This stage moves at your pace.
A detailed, itemised written estimate covering every element of the renovation. A clear contract with a milestone-based payment schedule and a specific start and completion timeline.
We submit all permit applications. While permits are processing, our CNC facility manufactures your custom vanity. Start date is confirmed for when permits are approved.

A full gut renovation of a standard bathroom (60 to 80 square feet) in Nassau County typically takes 3 to 5 weeks from permit approval to final walkthrough. A master bathroom renovation with larger tile format, custom glass, heated floors, and more complex tile patterns typically takes 4 to 6 weeks. Small half-bath updates take 2 to 3 weeks. These timelines assume standard permit processing (2 to 4 weeks) has already occurred before construction begins.
Yes, but it is significantly more disruptive and expensive than installing them during a full gut. Adding heated floors without removing all existing tile requires demolishing the current floor tile, installing the heating mat on the existing subfloor, adding a thin self-levelling layer if needed, then re-tiling. This means the floor work is a full gut while the rest of the bathroom may be left in place. For most Nassau County homeowners, if they are considering heated floors and their bathroom is already old enough to warrant renovation, the economics strongly favour a complete gut rather than a partial one.
For small bathrooms in Nassau County homes — which are common in post-war construction — the tile choice has a significant impact on how large the space feels. Larger format tiles (16×16 or 24×24) with minimal grout lines make a small bathroom feel more spacious. Light or neutral colours add visual space. Carrying the same tile from the floor up the shower wall (rather than two different materials) eliminates visual interruptions that make spaces feel smaller. Avoid heavily patterned tile throughout a small bathroom — use it as a feature accent instead.
This depends on your household and your Long Island neighbourhood. If your bathroom is the only full bathroom in the home, keeping at least one tub is strongly recommended from a resale perspective — many buyers with young children specifically require a tub. If it is a master bathroom and you have a second full bathroom with a tub elsewhere in the home, converting the master to a walk-in shower only is increasingly common and is well-received by buyers in Nassau County. Discuss the specific resale implications for your property with your real estate agent and your renovation contractor together before making this decision.
Six design moves that consistently make Nassau County bathrooms feel larger than they are: (1) Large format tile on floor and walls in a light or neutral colour; (2) A frameless glass shower enclosure rather than a curtain or framed surround; (3) A floating vanity that shows floor beneath it; (4) A large, unframed mirror that extends to near the ceiling; (5) Good recessed lighting that brightens all corners; (6) Eliminating visual clutter — built-in niches and recessed medicine cabinets replace surface-mounted storage.
A freestanding soaking tub is among the most requested features in master bathroom renovations across Nassau County right now. It creates an undeniable focal point and luxury atmosphere. Whether it is “worth it” depends on two things: do you actually take baths regularly (or genuinely intend to start), and does your master bathroom have the square footage to accommodate a freestanding tub without feeling overcrowded? A freestanding tub looks spectacular in a spacious master bathroom. In a smaller space, it can overwhelm the room and make it feel cramped. Lori, our design consultant, assesses every master bathroom renovation for proportional fit before recommending a freestanding option.
