Why Island Bath Studio

The Long Island bathroom crew that actually finishes.

Too many bathroom projects on Long Island go over on schedule. Most go over on budget. We built Island Bath Studio in 2012 to end that. One dedicated crew per job. Schluter-Certified waterproofing spec'd before we sign. Daily photo updates. Firm quote within 48 hours of walking your bathroom. We don't leave until the last tile is perfect.

Whether you need a bathroom remodel in Suffolk County NY — Huntington, Smithtown, Babylon, Islip, Commack, or Brookhaven — or a bathroom renovation in Nassau County, our licensed team handles permits, plumbing, waterproofing, and tile from start to finish. Suffolk County homes built in the 1960s–1980s often have cast-iron drains and galvanized supply lines that we replace during every full remodel. That upfront plumbing work is what separates a renovation that lasts from one that leaks in three years.

  • One crew per project — no rotating subs
  • Schluter Kerdi or Kerdi-Board on every shower
  • Nassau & Suffolk permits handled in-house
  • Daily cleanup, floor protection, dust containment
  • Firm, itemized quote — no ballparks
  • Daily photo updates + lead designer on-call

Suffolk County NY

Bathroom Remodel Suffolk County NY — Huntington to Brookhaven

Suffolk County bathroom renovations come with unique challenges that generic contractors miss. Many Suffolk County NY homes — particularly the ranches and split-levels in Huntington, Smithtown, Babylon, and Islip — were built on concrete slabs with cast-iron waste lines running under the foundation. A bathroom remodel in Suffolk County often requires rerouting drain lines through the ceiling of the floor below or core-drilling through the slab, work that demands a licensed plumber and a proper Suffolk County permit.

Our team pulls permits in every Suffolk County township — from the Town of Huntington to the Town of Brookhaven — and manages all inspections. We know which Suffolk inspectors want schematic drawings on-site and which accept digital submittals. A typical bathroom remodel in Suffolk County NY runs $8,000 for a guest bath update to $35,000+ for a full down-to-the-studs renovation with Schluter waterproofing, new plumbing, and floor-to-ceiling tile. See our full bathroom remodel Suffolk County guide for town-by-town permit details, cost ranges, and our process for slab and septic homes.

Suffolk County building permits for bathroom remodels are issued by individual town building departments, not by Suffolk County directly. The Town of Islip Building Department (covering Bay Shore, West Islip, East Islip, Brentwood, and Central Islip) and the Town of Brookhaven Building Department(Patchogue, Ronkonkoma, Port Jefferson, Lake Grove, and Coram) both require a permit for any bathroom work involving plumbing relocation, GFCI electrical, or structural changes. The Suffolk County Department of Public Works (DPW) regulates county roads and drainage — bathroom remodels within existing home footprints don't require DPW review, but any exterior drain line that ties into county infrastructure does. We assess DPW applicability at your free estimate.

Nassau County

Bathroom Renovation Nassau County — Garden City to Long Beach

Nassau County bathroom renovations present their own set of challenges distinct from Suffolk. Many Nassau County homes — the colonials in Garden City, the capes in Levittown, the split-levels in Massapequa — were built in the 1940s through 1960s with full basements and cast iron stack plumbing. During a full bathroom remodel, we replace the cast iron waste stack with PVC and swap galvanized supply with PEX — adding decades of life to your renovation.

Nassau County's building permit process is generally faster than Suffolk County's, with most bathroom renovation permits processing in 5-10 business days through the Town of Hempstead, Town of North Hempstead, or Town of Oyster Bay. Our team files permits in our name and manages all inspections through final sign-off. A typical bathroom renovation in Nassau County runs $10,000 for a guest bath update to $45,000+ for a master bath with layout changes and premium finishes.

Guest Bath (Nassau)

$10,000–$20,000

Vanity, toilet, tile, fixtures. Same footprint. Typical for Levittown capes and Hicksville ranches.

Full Remodel (Nassau)

$18,000–$40,000

Down to studs. Cast iron replaced. Schluter waterproofing. Full tile. Common in Garden City colonials.

Master Bath (Nassau)

$35,000–$65,000+

Double vanity, freestanding tub, walk-in shower, heated floor. Premium for Great Neck and Manhasset.

Bathroom renovation costs

Bathroom Remodel Cost — Suffolk County NY & Nassau County, 2026

Bathroom renovation costs on Long Island are shaped by three things: the age of the home, the scope of plumbing work, and your tile and fixture selections. Suffolk County NY and Nassau County homes built in the 1950s–1970s — the colonials, ranches, and split-levels that make up most of Long Island's housing stock — almost always have cast iron drain lines and galvanized supply piping that we replace during a full bathroom remodel. That plumbing work adds real cost but also real longevity to the finished product. A typical bathroom remodel in Suffolk County runs $8,000–$35,000 for a hall bath, depending on scope.

Guest Bath Update

$8,000–$18,000

Vanity, toilet, tile refresh, fixtures. No plumbing relocation. Same footprint.

Full Bathroom Remodel

$15,000–$35,000

Down to studs. New plumbing, Schluter waterproofing, tile, vanity, fixtures, permit.

Master Bath Addition

$30,000–$65,000

Freestanding tub, double vanity, walk-in shower, heated floor, permit. May include layout changes.

All costs include Nassau or Suffolk County permit filing. Prices vary based on linear footage of tile, fixture grade, and complexity of plumbing relocation. We walk every project on-site and deliver a firm, itemized quote within 48 hours. See detailed pricing →

Renovation types

Types of Bathroom Renovation — Which Scope Fits Your Home?

Not every bathroom renovation means ripping everything out. Understanding the different scopes helps you budget accurately and communicate clearly with contractors. Here are the five most common bathroom renovation types we perform across Nassau and Suffolk County.

Cosmetic Refresh

$5,000–$12,0001–2 weeks

New vanity, toilet, fixtures, paint, and mirror — without moving plumbing. Same footprint, same tile (or tile overlay). Ideal for guest baths or pre-sale updates. No permit required in most Nassau and Suffolk townships because no plumbing or electrical relocation is involved.

  • New vanity + countertop
  • Toilet replacement
  • Faucet + showerhead upgrade
  • Paint + accessories
  • Mirror + lighting swap

Full Gut Remodel

$15,000–$35,0003–4 weeks

Down to the studs. New plumbing supply and drain lines, Schluter Kerdi waterproofing, floor-to-ceiling tile, new vanity, toilet, and fixtures. This is the most common scope for Long Island hall baths built in the 1960s–1980s with aging cast iron drains and galvanized supply.

  • Complete demo to studs
  • New PEX supply + PVC drain
  • Schluter waterproofing
  • Floor-to-ceiling tile
  • All new fixtures + glass

Tub-to-Shower Conversion

$12,000–$25,0002–3 weeks

Remove the bathtub, rebuild framing and subfloor, install a walk-in shower with proper waterproofing and tile. Requires a building permit in both Nassau and Suffolk County because it involves plumbing modification. Adds accessibility and modern appeal to older Long Island homes.

  • Tub removal + disposal
  • Framing rebuild
  • New shower pan + drain
  • Schluter Kerdi membrane
  • Frameless glass enclosure

Master Bath Renovation

$30,000–$65,000+4–6 weeks

The premium scope: freestanding tub, double vanity, oversized walk-in shower with bench, heated floor, floor-to-ceiling tile, custom lighting. May include layout changes or expanding into an adjacent closet. Plumbing relocations, permits, and custom stonework all factor into cost.

  • Freestanding soaking tub
  • Double vanity + quartz
  • Curbless walk-in shower
  • Heated porcelain floor
  • Custom tile design

Accessible / Aging-in-Place

$18,000–$40,0003–5 weeks

Curbless zero-threshold shower, reinforced grab bars, comfort-height toilet, wider 36-inch doorway, non-slip flooring, handheld sprayer, fold-down bench. Designed to look beautiful while meeting accessibility needs. Our founder specializes in aging-in-place design that avoids the institutional look.

  • Curbless shower entry
  • Grab bars (blocking in walls)
  • Comfort-height toilet
  • 36" doorway widening
  • Non-slip tile + bench seat

Walk-In Shower Installation

$8,000–$20,0002–3 weeks

New walk-in shower construction — either in an existing shower footprint or converted from a tub space. Schluter Kerdi waterproofing on all surfaces, tile to ceiling, niche, bench option, thermostatic valve, and frameless glass. The most requested single service for Suffolk County bathroom renovations.

  • Kerdi waterproofing system
  • Large-format wall tile
  • Linear or center drain
  • Niche + bench option
  • Frameless glass door/panel

How to Choose the Right Scope for Your Suffolk County or Nassau County Bathroom

Your plumbing age determines scope

Most Long Island homes built before 1985 have cast iron drain lines and galvanized supply pipes. If you are opening walls for a remodel, replacing this aging plumbing now prevents a separate emergency project in 5–10 years. This upgrades a cosmetic refresh to a full gut — but it is the right decision for longevity.

Suffolk County permit considerations

Any bathroom remodel in Suffolk County NY that involves plumbing relocation, electrical changes, or structural modifications requires a building permit. We file with the Town of Huntington, Town of Smithtown, Town of Babylon, Town of Islip, or Town of Brookhaven depending on your address. Permit fees run $150–$500 and are included in our project estimates.

ROI and resale considerations

On Long Island, a mid-range bathroom remodel returns approximately 60–67% of cost at resale (Remodeling Magazine, 2025). However, the real value is in daily use — you will use your bathroom 6–8 times per day for 15–20 years before selling. Invest in waterproofing and plumbing quality; save on decorative elements if budget is tight.

Suffolk County

Bathroom Remodel Suffolk County NY

Bathroom remodel Suffolk County NY projects require a contractor who knows the housing stock, the town permit systems, and the cesspool-specific fixture requirements that apply to a large portion of Suffolk homes. Island Bath Studio has completed over 350 bathroom remodels across the County of Suffolk — from 1960s ranch homes in the Town of Babylon to 1980s colonials in Commack and 1990s townhomes in Ronkonkoma.

Each of the five major Suffolk building departments — Town of Huntington (100 Main Street, Huntington, NY 11743), Town of Smithtown (99 West Main Street, Smithtown, NY 11787), Town of Islip (655 Main Street, Islip, NY 11751), Town of Babylon (200 East Sunrise Highway, Lindenhurst, NY 11757), and Town of Brookhaven (1 Independence Hill, Farmingville, NY 11738) — has its own permit application format, fee schedule, and inspection sequence. We file with the correct department for your address and have the submission formats and inspector contacts on file for every one. Permit turnaround in Suffolk County typically runs 10 to 14 business days for standard bathroom work.

Suffolk County also has a much higher proportion of homes served by cesspool or private septic rather than municipal sewer — particularly in the Town of Islip, Town of Brookhaven, and portions of the Town of Babylon. On every Suffolk County bathroom remodel we complete, we specify 1.28 gpf WaterSense-certified toilets and 1.75 gpm showerheads as standard to reduce hydraulic load on the cesspool system. Adding a bathroom where none previously existed may require a Suffolk County Department of Health Services review; we flag this at the estimate if it applies to your project and no municipal sewer connection exists.

Bathroom Renovation Long Island — Questions We Answer Most

On Long Island, a full bathroom renovation typically runs $18,000–$45,000 for a hall bath and $30,000–$80,000+ for a master bath, depending on scope, tile choice, and fixture quality. We walk every project on-site and give a firm, itemized number. No ballparks, no surprises.

Most hall-bath remodels take 3–4 weeks from demo to final walkthrough. Master baths with plumbing relocations or custom tile run 4–6 weeks. We dedicate one crew to your project — we don't start three jobs and disappear.

Yes, if the work includes plumbing, electrical, or structural changes (tub-to-shower conversions, wall relocations, new venting). We pull the permit and manage the inspection for you. Cosmetic-only jobs (tile, vanity, fixtures) usually don't need one.

Schluter-Systems Kerdi sheet membrane or Kerdi-Board on every shower wall and pan. We're Schluter-Certified installers. No mesh-tape-and-hope jobs, no black-paint-on-cement-board shortcuts.

Yes. Curbless showers, reinforced grab-bar blocking, comfort-height toilets, wider 36" doorways, handheld sprayers, fold-down bench seats. Founder Angela Ferreira specializes in accessible design.

A bathroom remodel in Suffolk County NY typically costs $8,000–$18,000 for a guest bath update (vanity, toilet, tile refresh) and $15,000–$35,000 for a full down-to-studs renovation with new plumbing, Schluter waterproofing, and floor-to-ceiling tile. Master bath renovations in Suffolk County run $30,000–$65,000+ depending on scope. We provide a firm, itemized quote after an on-site walkthrough.

Our 7-step process: (1) Free on-site estimate with plumbing assessment, (2) Design consultation with material selection and 3D rendering, (3) Permit filing with Nassau or Suffolk County and material ordering, (4) Demo and rough-in including plumbing and electrical, (5) Schluter Kerdi waterproofing on all shower surfaces, (6) Tile installation, vanity, fixtures, glass, and finish work, (7) Building inspection, punch list, and final walkthrough. A standard hall bath takes 3–4 weeks from demo to completion. We assign one dedicated crew per project — no rotating subs or juggling multiple jobs.

We serve all of western and central Suffolk County from our Mineola studio. Core areas include Huntington, Smithtown, Commack, Babylon, Islip, Bay Shore, Brentwood, Dix Hills, East Northport, Hauppauge, Kings Park, Melville, Northport, Patchogue, Ronkonkoma, Central Islip, Deer Park, East Islip, West Islip, West Babylon, and Lindenhurst. We estimate at no charge for any Suffolk County home within 45 miles of our studio. Each Suffolk town has its own building department and permit process — we handle filing, inspections, and closeout for every project.

For Suffolk County homes served by cesspool or septic systems, we specify WaterSense certified low-flow fixtures — 1.28 gpf toilets and 1.75 gpm showerheads. These reduce hydraulic load on the septic system without sacrificing performance. We also advise against installing water softeners on septic systems. Our team notes septic status during every Suffolk County estimate and adjusts our fixture specifications accordingly.

The key differences are: (1) Housing stock — Suffolk County homes (especially in Huntington, Smithtown, Babylon, and Islip) were often built on slabs or with concrete block foundations, requiring different approaches to drain line routing than Nassau County's older homes with full basements. (2) Permits — each Suffolk town (Huntington, Smithtown, Babylon, Islip, Brookhaven) has its own building department; Nassau County is organized under town governments that cover larger areas. (3) Septic systems — a much higher percentage of Suffolk County homes use cesspool or septic rather than municipal sewer, which affects fixture selection. We have extensive experience navigating both counties and handle all permitting regardless of location.

We serve all of Nassau and Suffolk County for bathroom renovations. Nassau County: Garden City (11530), Hempstead (11550, 11551), Great Neck (11020, 11021, 11023), Levittown (11756), Massapequa (11758), Hicksville (11801), Syosset (11791), Mineola (11501), Floral Park (11001), Oceanside (11572), Long Beach (11561), Valley Stream (11580, 11581), Merrick (11566), Bellmore (11710), Wantagh (11793), Westbury (11590). Suffolk County: Huntington (11743, 11746), Smithtown (11787), Commack (11725), Babylon (11702, 11703), Islip (11751, 11769), Bay Shore (11706), Patchogue (11772), Ronkonkoma (11779), East Northport (11731), Dix Hills (11746), Melville (11747), Northport (11768), Kings Park (11754), Sayville (11782), Deer Park (11729), West Babylon (11704), Central Islip (11722), Lindenhurst (11757), and Brentwood (11717).

A walk-in shower installation on Long Island typically costs $8,000–$20,000 depending on the size of the shower, tile selection, and whether you are converting from an existing tub (which requires additional framing and plumbing work). The price includes Schluter Kerdi waterproofing, floor-to-ceiling tile, a linear or center drain, shower niche, and frameless glass panel or door. Tub-to-shower conversions add $2,000–$4,000 for the demo, framing rebuild, and plumbing modification. Permits are required in both Nassau and Suffolk County for tub-to-shower conversions.

Yes. We handle co-op and condo bathroom renovations across Long Island, including buildings in Great Neck, Manhasset, Long Beach, Rockville Centre, and Garden City. Co-op and condo renovations require board approval and an alteration agreement in addition to township permits. We prepare the scope-of-work documents, insurance certificates, and contractor information that most Long Island co-op boards require. We also coordinate with building management for work hours, elevator reservations, and common-area protection.

We work with all major tile brands available through our Long Island suppliers. Our most-specified lines include Porcelanosa (available at their Westbury showroom), Daltile, Florida Tile, and Emser. For natural stone, we source from local fabricators in the Long Island/NYC metro area. We accompany clients to tile showrooms during the design phase and advise on durability, maintenance, and cost-per-square-foot to keep your project on budget.

Yes — bathroom remodeling in Suffolk County NY is our core market. We serve all of western and central Suffolk County including the Town of Huntington, Town of Smithtown, Town of Babylon, Town of Islip, and Town of Brookhaven. Our Suffolk County Home Improvement Contractor license covers every township, and we pull all permits ourselves. We have completed over 350 bathroom remodels in Suffolk County since 2012.

We serve every town in western and central Suffolk County for bathroom remodeling: Huntington (including Commack, Dix Hills, East Northport, Melville, Northport), Smithtown (Kings Park, Hauppauge, Nesconset, St. James), Babylon (West Babylon, North Babylon, Lindenhurst, Deer Park, Copiague), Islip (Bay Shore, East Islip, West Islip, Brentwood, Central Islip), and Brookhaven (Patchogue, Ronkonkoma, Lake Ronkonkoma, Port Jefferson). We travel within 45 miles of our Mineola studio.

A bathroom remodel in Suffolk County NY typically costs $8,000–$18,000 for a guest bath update (vanity, toilet, tile refresh, no plumbing relocation), $14,000–$33,000 for a full gut remodel down to the studs with PVC drain, PEX supply, Schluter waterproofing, and floor-to-ceiling tile, and $28,000–$60,000+ for a master bath renovation with walk-in shower, double vanity, and heated floor. Suffolk County permit fees ($150–$400) are included in all our estimates.

A standard hall bath remodel in Suffolk County takes 3–4 weeks from demo day to final walkthrough. Master bath renovations with plumbing relocations or custom tile run 4–6 weeks. We assign one dedicated crew to your Suffolk County project — no rotating subcontractors pulling us between jobs. Permit issuance from Suffolk County town building departments typically adds 5–15 business days before we can break ground.

Yes, in most cases. Any bathroom remodel in Suffolk County NY that involves moving plumbing (toilet, shower drain, supply lines), adding or upgrading electrical (heated floor circuit, GFCI outlets, new exhaust fan wiring), or structural changes (enlarging the bathroom, moving a wall) requires a building permit from the applicable town building department — Town of Huntington, Smithtown, Babylon, Islip, or Brookhaven. Cosmetic-only work such as replacing a vanity in place or swapping tile over existing backer board typically does not require a permit. We assess permit requirements at your free estimate and handle all permit filings and inspections ourselves.

Suffolk County Service Areas

Bathroom Remodel Suffolk County NY — Town by Town

Each Suffolk County town has its own building department and permit process. We serve all of western and central Suffolk — from Huntington and Commack in the north to Babylon and Islip in the south.

What Makes Bathroom Remodeling in Suffolk County Different

Suffolk County's housing stock — dominated by ranches and split-levels built between 1955 and 1975 — presents specific plumbing and structural challenges that require experienced local contractors. The most common issue we encounter in Huntington, Smithtown, Commack, Babylon, and Islip bathrooms is cast iron waste lines and galvanized supply pipes that have reached the end of their service life. We replace these as a matter of course in any full gut remodel — extending the life of the renovation by decades.

Many Suffolk County homes are on cesspool or septic systems rather than municipal sewer. For these homes, we specify WaterSense low-flow fixtures (1.28 gpf toilets, 1.75 gpm showers) to reduce hydraulic load on the septic system without compromising performance.

Every bathroom remodel in Suffolk County involving plumbing relocation, electrical work, or structural changes requires a permit from the applicable town building department. We file with the Town of Huntington, Town of Smithtown, Town of Babylon, Town of Islip, or Town of Brookhaven depending on your address — and we manage all inspections through final sign-off.

Suffolk County Cost Guide

Suffolk County Bathroom Remodel Cost Guide — 2026

Bathroom remodel costs in Suffolk County NY vary by scope, plumbing condition, tile selection, and which town your home is in. Most Suffolk County homes were built between 1950 and 1980 — ranches and split-levels in Huntington, Smithtown, Babylon, and Islip — with cast iron drain lines and galvanized supply piping that we replace during every full gut remodel. That plumbing work is the biggest cost driver in Suffolk County that generic contractors often underquote.

ScopeCost Range
Basic Refresh (Suffolk County)$5,000–$12,000
Mid-Range Full Remodel$12,000–$25,000
High-End / Master Bath$25,000–$50,000

All Suffolk County estimates include permit filing with the applicable town building department (Town of Huntington, Smithtown, Babylon, Islip, or Brookhaven). Permit fees of $150–$400 are included in our quoted price. We walk every project on-site and deliver a firm itemized quote within 48 hours.
