If you are a Long Island homeowner researching bathroom remodeling costs, the honest answer is: it depends — but not in a vague, unhelpful way. Cosmetic refreshes run $8,000–$18,000. Mid-range gut-and-rebuild projects land between $18,000 and $40,000. Full luxury renovations with custom tile, steam showers, and radiant-floor heat can reach $60,000 or more. Below, we break down exactly what drives those numbers so you can budget realistically before you call a contractor.
What the Numbers Actually Include
Bathroom remodel estimates cover more than tile and fixtures. On Long Island, a complete project typically includes demolition, rough plumbing, rough electrical, insulation and cement board, tile work, fixture installation, vanity and cabinetry, and finish work. Labor alone accounts for 40–60 percent of total cost in the New York metro market, which runs higher than national averages due to union labor rates, licensing requirements, and the cost of doing business in Nassau and Suffolk counties.
Rough Cost Tiers for Long Island (2026)
- Basic refresh (no layout change): $8,000–$18,000. New fixtures, vanity, toilet, paint, and basic tile. Existing plumbing and electrical stays in place.
- Mid-range remodel: $18,000–$40,000. Full demo and rebuild, updated plumbing rough-in, new tub or walk-in shower, tile floor and walls, quality vanity, exhaust fan upgrade, recessed lighting.
- High-end / primary bath: $40,000–$70,000+. Custom tile work, niche shelving, frameless glass enclosures, freestanding soaking tub, dual vanity, heated floors, and designer fixtures.
These figures reflect a standard 50–80 sq. ft. bathroom. Master baths over 100 sq. ft. or projects that move the toilet or shower drain — which requires breaking the concrete slab or opening the subfloor — add cost quickly. Our bathroom remodeling team can tell you in the first site visit whether your layout changes are plumbing-intensive.
Long Island-Specific Factors That Affect Your Budget
Permits and Inspections
Any structural change, electrical panel work, or relocation of plumbing in Nassau or Suffolk County requires a building permit. Towns like Babylon, Huntington, and Islip each have their own permit offices and inspection schedules. Permit fees typically run $200–$600 for a residential bathroom, but the inspection timeline — which can add two to four weeks to a project — is the bigger consideration. Working with a licensed contractor who pulls permits protects your homeowner's insurance and your certificate of occupancy when you eventually sell. Milton's Construction handles permitting as part of every project.
Older Housing Stock
West Babylon and most of western Suffolk County have significant post-war housing stock — Capes, ranch homes, and split-levels built in the 1950s and 1960s. These homes frequently have galvanized steel supply lines that need replacement, undersized drain lines, and knob-and-tube or early aluminum wiring that does not meet current code. Budget $1,500–$4,000 for plumbing upgrades in a pre-1980 home, and coordinate with a licensed electrician for panel or wiring work. Our licensed plumbing team handles rough-in and fixture connections in-house, which keeps the project on schedule.
Moisture and Mold
Long Island's humid summers and poorly ventilated older bathrooms create persistent moisture problems. When you open a wall, it is common to find mold remediation, wet insulation, or rotted subfloor sheathing. Budget a 10–15 percent contingency specifically for hidden conditions. Skipping this buffer is the single most common reason bathroom projects go over budget.
What Drives Cost Up or Down
- Tile selection: Builder-grade ceramic starts around $2/sq. ft.; large-format porcelain or natural stone runs $8–$20/sq. ft. or more before installation labor.
- Shower vs. tub: A custom tiled walk-in shower with a linear drain costs more than a standard alcove tub/shower combo. Freestanding tubs add fixture cost and require a floor-mount or deck-mount faucet.
- Vanity size and type: A 36-inch stock vanity is $400–$1,200. A 72-inch custom double vanity with solid-surface top runs $2,500–$6,000 or more.
- Scope creep: Changing the tile selection mid-project, adding a heated floor after demo, or upgrading to a frameless shower after the rough-in is framed all add cost. Finalize your selections before demo day.
Timeline: How Long Does a Bathroom Remodel Take?
A standard mid-range remodel in Suffolk County takes three to five weeks from demo to punch-list, assuming permits are pulled in advance and materials are ordered before the start date. High-end projects with custom tile work or specialty fixtures run five to eight weeks. The permit inspection cadence — rough plumbing, rough electrical, then final — is the primary schedule driver on jobs that require municipal review.
Financing Your Remodel
A full bathroom renovation is a significant investment, but it consistently delivers strong return on investment in the Long Island real estate market — typically 60–70 percent cost recovery at resale, plus the daily-use value you get for as long as you live there. Milton's Construction works with Enhancify financing, which lets you check your rate with no impact to your credit score. Options include fixed-rate home improvement loans that keep monthly payments predictable.
Why Hire a Licensed General Contractor for a Bathroom Remodel?
Bathroom remodeling involves at minimum three licensed trades: general contracting, plumbing, and electrical. Hiring individual subcontractors and managing them yourself is feasible, but coordinating their schedules around permit inspections is a part-time job. A full-service general contractor like Milton's Construction manages the sequence, pulls the permits, and is the single point of accountability if anything is not right. Our architecture and design team can also help you plan the layout before a single tile is selected, which prevents costly mid-project revisions. You can see examples of completed projects in our project gallery.
