What a Bathroom Renovation Costs on Long Island in 2026

Ask ten contractors what a bathroom renovation costs on Long Island and you'll get ten ballparks. Most of them are either too low (to win the bid) or too high (so they can “discount” you to feel like you got a deal). We'd rather tell you the truth.

After 640+ bathrooms across Nassau and Suffolk, here's what you actually pay.

Hall Bathroom Refresh: $18,000 – $28,000

The entry-level project. Same layout, same footprint, better materials. Replace vanity, toilet, tile, fixtures. Maybe swap the tub surround. Schluter waterproofing on any wet areas. Ceramic or porcelain tile. Mid-range Moen or Kohler fixtures.

This works for postwar Levittown capes, Garden City colonial second bathrooms, Hicksville ranch halls — any 5x8 or 5x9 bathroom with the layout you can live with.

Hall Bathroom Full Remodel: $28,000 – $45,000

Full gut to studs and subfloor. New plumbing rough-in (often needed — many Long Island homes still have galvanized supply lines and cast iron drains). New framing, Schluter Kerdi-Board substrates, large-format porcelain tile, custom tile shower with niche and bench, frameless glass enclosure, floating or custom vanity, LED mirror, exhaust fan with humidity sensor.

This is the most common Long Island project. About 60% of what we do. Plan 4–5 weeks from demo to final.

Master Bathroom Renovation: $30,000 – $95,000+

Full master suite rebuild. Freestanding soaking tub, separate walk-in shower (usually curbless), double vanity with quartz or marble top, heated porcelain floor, floor-to-ceiling tile, premium fixtures.

The spread is huge because master baths vary wildly in size and finish. A Great Neck estate with marble and Dornbracht fixtures lands near $95K. A Smithtown split-level master with mid-range porcelain and Kohler fixtures lands near $38K.

Tub-to-Shower Conversion: $10,000 – $22,000

The #1 request from aging-in-place homeowners. Remove old tub, build a walk-in shower in the same footprint. Schluter Kerdi waterproofing, Kerdi-Line linear drain, 12x24 porcelain or subway tile, thermostatic valve with handheld sprayer, frameless glass.

Nassau and Suffolk both require a permit for this. We handle it.

Walk-In Shower Only: $12,000 – $32,000

Isolated shower build, usually because the existing shower is leaking or the tile is cracking. Full Schluter system, new pan, new waterproofing, new tile (porcelain, marble, or mosaic), linear drain, frameless glass, thermostatic valve.

Range depends on tile choice. Basic 12x24 porcelain is the low end. Calacatta marble is the high end. Labor alone for marble adds $1,500–$2,500.

Accessible / ADA Bathroom: $15,000 – $48,000

Zero-threshold shower, slip-resistant porcelain, blocking in walls for grab bars, ADA-compliant grab bars (304 stainless), comfort-height toilet, 36" door widening or pocket door retrofit, thermostatic anti-scald valve, fold-down bench seat.

The range depends on whether structural work is needed for door widening. If we have to cut a load-bearing wall or bring in an engineer, you're in the upper half.

What drives the cost up or down

Six factors move the number. Plumbing relocation — moving a toilet costs $1,500–$3,000 in extra labor. Tile choice — marble doubles install time vs porcelain. Fixture tier — Moen to Grohe to Dornbracht swings $2,000–$6,000. Structural condition — rotted subfloor or knob-and-tube add $1,500–$4,000 depending on extent. Heated floor — adds $1,200–$2,500. Frameless glass — $1,000–$2,500.
