Master Bathroom Remodel on Long Island: Ideas & Cost Guide

The master bathroom is the one room in your Long Island home where you can invest heavily and see it pay off — both in daily enjoyment and resale value. Whether you're in a colonial in Garden City, a ranch in Commack, or a split-level in Massapequa, upgrading your master bath is one of the best renovation decisions you can make. Here's what it costs and what Long Island homeowners are choosing in 2026.

What Does a Master Bathroom Remodel Cost on Long Island?

A master bathroom remodel in Nassau or Suffolk County typically falls between $22,000 and $45,000, depending on the size of the space and the finishes you select. Some high-end projects in areas like Great Neck, Manhasset, or Cold Spring Harbor exceed $60,000 when custom tile work, steam showers, and high-end fixtures are involved.

Mid-range master bath ($22,000–$32,000): New walk-in shower with tile surround and frameless glass door, double vanity with quartz top, new tub or freestanding soaker, tile floor, updated lighting and exhaust fan. This is the sweet spot for most Long Island homeowners looking to modernize without going all-out.

High-end master bath ($32,000–$55,000+): Curbless walk-in shower, rain head plus body sprays, radiant heated floor, custom tile work throughout, premium freestanding tub, double vanity with custom cabinetry, smart mirror, and designer fixtures. Projects at this level require experienced tile setters and a contractor with proven high-end experience.

Most Popular Master Bath Features on Long Island in 2026

Walk-in showers with frameless glass: The single most requested feature. Long Island homeowners are removing old tub-shower combos and replacing them with large walk-in showers. Frameless glass enclosures cost $800–$2,000 just for the glass — but they make small bathrooms feel twice as large.

Freestanding soaking tubs: These remain popular in larger master baths. An acrylic freestanding tub costs $600–$2,000 for the fixture; installation adds $500–$1,500 depending on plumbing requirements. Be realistic about usage — many homeowners request them, but actual soaking frequency is lower than expected.

Double vanities: Standard in any master bath remodel today. A 60-inch double vanity with quartz top and soft-close drawers runs $1,200–$3,500 for materials alone. Installation adds $400–$800. Custom built-ins are available at a premium.

Heated floors: Electric radiant heating mats are a Long Island favorite given cold winters. The system costs $600–$1,500 installed under tile. Operating cost is low — a typical master bath uses about 150–300 watts per hour. Worth every penny on January mornings in Nassau County.

Large-format tile: 24x24 and 24x48 porcelain tiles are dominant in 2026. They create a seamless, high-end look. They're also harder to install — requiring perfectly level subfloors and experienced tile setters. On Long Island, budget $12–$18/sqft installed for large-format porcelain.
