What a full bathroom remodel includes
A full bathroom remodel replaces the fixtures, surfaces, and often the layout of the room, not just the finishes you can see. On a typical Long Island project that means demolition, any plumbing and electrical rough-in, waterproofing, tile for floors and walls, a new tub or shower, a vanity and countertop, toilet, lighting, ventilation, mirrors, and hardware. Many of our clients also correct hidden problems at the same time: dated wiring, poor exhaust, or water damage behind old tile. Because our own crews handle the whole scope, the plumbing, tile, and cabinetry all get coordinated instead of handed between separate contractors.
The design-build advantage: one team, one showroom, one contract
The design-build model means you hire a single company for design, materials, and construction instead of juggling a designer, a supplier, and a contractor separately. At D&V, you plan the space with an in-house designer, choose every fixture and finish in our East Northport showroom, and have the build managed by a dedicated project manager, all under one written proposal. That removes the finger-pointing that happens when the tile setter blames the plumber, keeps pricing transparent, and lets us pull and manage the permits your town requires for plumbing or structural work. You can see completed bathrooms in our project portfolio.
How much a bathroom remodel costs on Long Island
Most full bathroom remodels start in the low-to-mid five figures, with the national midrange full bath running roughly $23,000 to $25,000 according to Zonda’s 2025 Cost vs Value report. Long Island typically runs above that national average because of local labor and permit costs. A powder room or half-bath sits well below that range, while a primary or spa bathroom with a freestanding tub, custom tile, and high-end fixtures can reach six figures. The biggest cost drivers are the tile and stone package, the shower system, and whether you move plumbing to change the layout. Rather than quote a number sight unseen, we give a general estimate at your free consultation and then a detailed, line-item written proposal after an in-home measurement.
How long a bathroom remodel takes
Once materials are on site, most bathroom construction runs about two to four weeks. Design, selections, and permitting happen before that, and the schedule can stretch when you specify custom vanities, imported tile, or a made-to-order glass enclosure that has to be ordered and delivered first. Ordering everything up front and staging it before demolition is how we keep a bathroom on schedule, and your project manager gives you the timeline in writing before work begins.
Where we work: Nassau, Suffolk, NYC, and the Hamptons
We remodel bathrooms across all of Long Island and beyond. That includes Nassau and Suffolk Counties (Huntington, Northport, Commack, Smithtown, Melville, Syosset, Great Neck, Garden City, and surrounding towns), all five boroughs of New York City, Westchester, and the Hamptons. For NYC apartments we work co-op and condo compliant: we handle certificates of insurance, alteration agreements, and building elevator reservations so your renovation clears the board and building management. In the East End we hold East Hampton, Southampton, and Shelter Island town licenses in addition to our Suffolk (#HI-71989), Nassau (#202187), NYC (HIC #2100175-DCA), and Westchester (#WC-38277-H24) licensing.
Materials and fixtures from our showroom
You choose every fixture and finish in one place: our East Northport showroom carries 431 brand partners so you are not shopping tile at one store and faucets at another. That includes plumbing and fixture lines like Kohler, Toto, Grohe, Hansgrohe, Duravit, and Villeroy & Boch, plus a full range of porcelain, ceramic, and natural-stone tile and designer plumbing fixtures, lighting, and vanities. We sell materials to homeowners, designers, and contractors with or without a construction contract, and we run a discount tile program. If you would rather browse first, ask about a private chauffeur to the showroom or a 3D Matterport tour, and see the full list of brand partners.
Our four-step process
Every bathroom project follows the same clear path so you always know the next step:
- Free consultation: we discuss your goals and give a general estimate, at the showroom or over the phone.
- In-home estimate: we take measurements and evaluate the existing plumbing, structure, and ventilation in your bathroom.
- Detailed written proposal: you receive line-item costs, a timeline, and a full materials list, with nothing hidden.
- Construction: a dedicated project manager oversees the build from demolition to final walkthrough.
Accessibility and aging-in-place options
Yes, we design bathrooms for safety and easier access. Common options include a tub-to-shower conversion for a low or curbless entry, a walk-in tub for safe soaking, grab bars, comfort-height fixtures, and custom glass shower doors measured and installed to fit. These upgrades work as a standalone project or as part of a full remodel, and our designers can blend the safety features into the look of the room so it reads as a spa bath, not a medical one.
