What We Do

Our Bathroom Renovation Services

Every scope below is performed by licensed trades under a single general contract, sequenced so waterproofing and rough-in are inspected before tile goes up.

Custom Design and Layout Reconfiguration

Outdated bathroom layouts waste space and create daily frustration. We redesign floor plans that improve flow, expand storage, and accommodate modern fixtures. For NYC apartments with small bathrooms, strategic layout changes — relocating the toilet to free up shower space, or converting a tub-shower combo to a walk-in shower with a linear drain — can transform a cramped bathroom into a functional retreat. Our team handles structural assessments, architectural drawings, and DOB filings when layout changes require permits.

Shower and Tub Installation

Modern shower enclosures require proper waterproofing membranes, slope-to-drain mud beds, and structural support for frameless glass panels. We install walk-in showers with a rubber waterproofing membrane topped by a liquid-applied waterproofing coat, curbless entries for accessibility, and custom niches for storage. For soaking tubs we verify floor load capacity — critical in pre-war NYC apartments where original joists may need reinforcement. Our licensed plumbers handle drain rough-ins, supply connections, and mixing valve installation to code.

Tile Work and Waterproofing

Proper waterproofing is the most critical element of any bathroom renovation in NYC. In showers we build a two-layer system — a rubber waterproofing membrane installed first, then a liquid-applied waterproofing coat over it — before any tile goes up. Our tile setters install porcelain, ceramic, natural stone, and large-format tiles with proper thinset coverage, expansion joints, and grout selection for long-term performance. Material options range from classic subway tile to contemporary large-format slabs, with custom mosaic accents for shower floors and niches.

Vanity and Countertop Installation

We install single and double vanities with quartz, marble, or solid surface countertops templated for undermount sinks and proper faucet hole placement. For small NYC bathrooms, we design floating vanities that create visual space while providing storage, or custom built-in vanities that maximize every inch of available wall space.

Plumbing and Electrical Upgrades

Bathroom renovations frequently require updated plumbing and electrical systems to meet current code. We install GFCI-protected outlets, exhaust fan circuits, and heated floor wiring for modern bathroom functionality. Our plumbers replace galvanized supply lines with copper, install new shut-off valves, and upgrade cast iron waste and drain assemblies to NYC code — addressing the corroded infrastructure common in pre-war NYC buildings.

Flooring Removal and Installation

We remove existing tile, vinyl, or damaged subfloor and prepare the substrate with proper leveling compounds and moisture barriers before installing new materials. Options include porcelain tile, natural stone, luxury vinyl plank, and heated floor systems — each installed with appropriate underlayment and waterproofing for wet-area performance.

Cost

How Much Does a Bathroom Renovation Cost in NYC?

Bathroom renovation costs in New York City vary significantly based on scope, materials, and property type. Here are general ranges based on our project history.

Cosmetic Update
$10,000–$20,000

New vanity, fixtures, paint, hardware

Mid-Range Remodel
$20,000–$40,000

New tile, vanity, shower/tub, fixtures, lighting

Full Gut Renovation
$40,000–$75,000+

Layout changes, plumbing/electrical relocation, custom everything

Several factors impact cost in NYC specifically

  • Co-op and condo board requirements add administrative costs for alteration agreements, insurance certificates, and building management coordination
  • Pre-war buildings often require additional work for corroded cast iron drain stacks and galvanized supply lines
  • Material delivery logistics in Manhattan (elevator reservations, street parking permits, loading dock scheduling) can add to labor costs
  • DOB permit fees and expeditor costs vary by scope
  • Waterproofing failures are expensive to remediate — we never cut corners on membrane systems

We provide itemized estimates that separate demolition, waterproofing, plumbing, electrical, tile, fixtures, and labor so you know exactly where your budget goes. When a bathroom is part of a larger scope, it is often more economical to bundle it with an apartment renovation or kitchen remodel on the same permit and delivery schedule.

Property Types

Bathroom Renovations for Every NYC Property Type

Building stock drives scope. Apartment stacks, brownstone cast iron, and co-op alteration agreements each demand a different approach.

Apartment Bathroom Remodeling

NYC apartment bathrooms present unique challenges — limited square footage, shared plumbing stacks, noise restrictions, and building management requirements. We navigate co-op board approvals, alteration agreements, and DOB filings so you don't have to. Our experience with pre-war and post-war apartment plumbing means we know how to work with existing stack locations and vent configurations.

Brownstone and Townhouse Bathrooms

Historic brownstones and townhouses often feature original cast iron plumbing and small bathroom footprints on upper floors. We handle structural modifications to expand bathrooms, add en-suite facilities, or convert closets into powder rooms — including landmark-compliant renovations in designated historic districts.

Co-op and Condo Bathroom Renovations

Board approval processes vary by building, but we maintain all required documentation — insurance certificates, contractor licenses, work schedules, architectural plans, and noise mitigation protocols — ready to submit. Our familiarity with building management requirements across hundreds of NYC buildings reduces approval timelines.

Process

Our Bathroom Renovation Process

Five phases, in order, with permits and board approvals cleared before demolition begins.

  1. 1

    On-Site Consultation

    We visit your property, take measurements, discuss your design goals, and assess existing conditions including plumbing, electrical, waterproofing, and structural elements.

  2. 2

    Design and Estimate

    Based on the consultation, we prepare a detailed scope of work with an itemized cost breakdown. We review material options, fixture selections, and layout configurations.

  3. 3

    Permits and Approvals

    We file DOB applications, coordinate with co-op/condo boards, and obtain all required permits before any work begins.

  4. 4

    Demolition and Construction

    Our crews handle demolition, rough-in (plumbing, electrical), waterproofing, tile installation, and all finish work — vanities, fixtures, mirrors, accessories, and final paint.

  5. 5

    Final Inspection and Walkthrough

    We coordinate DOB inspections, obtain sign-offs, and conduct a detailed walkthrough with you to confirm everything meets specifications before closeout.
