Bathroom remodels for Seaford homes, from tight Levitt-era full baths to spa-quality primary suites and flood-conscious layouts on canal-front properties.
The bathrooms in Seaford's original Cape Cods and ranches were functional but small — five-by-seven full baths with cast iron tubs, single-handle faucets, and ventilation that exhausted into the attic instead of outside. After forty years those systems are reaching the end of their service life, and today's families expect a bathroom that does more than the minimum. A proper renovation in a Seaford home means replacing aging supply lines and drain stacks, bringing ventilation up to code, and often reconfiguring the layout to gain usable space within the same footprint.
For homes south of Merrick Road in FEMA flood zones, bathroom location and waterproofing assembly are design considerations from day one. Ground-floor bathrooms on flood-prone lots need vapor barriers, waterproof membrane systems behind tile, and flood-rated materials that do not harbor mold when wet. We have been doing this work on South Shore Nassau properties for four decades and we know what holds up and what does not.

Many Seaford Capes were built with one full bath and, if the attic was finished, a half bath upstairs that later homeowners converted. Converting that half bath to a full bath, adding a second full bath off the primary bedroom, or combining two small bathrooms into one larger space are common projects in this housing stock. All of them involve plumbing rough-in changes, new ventilation ductwork to the exterior, and a Town of Hempstead Building Department permit. We manage every part of that work with our in-house crew.
Our frame-to-finish approach means the tile setter, the plumber, and the trim carpenter are all working on the same timeline under the same project manager. There is no three-week gap between rough plumbing and the tile crew showing up because one subcontractor is running behind. Cost for a bathroom remodel in Seaford varies with scope and finish — a free written estimate gives you the exact number for your home.


A bathroom on the ground floor of a canal-front Seaford home needs a waterproofing system that goes beyond standard builder practice. We use continuous waterproof membrane systems behind all tile surfaces, not just the shower surround. Flooring goes over cement board, not plywood. Vanity cabinets are solid or marine-grade, not particle board with a veneer. These choices cost a modest premium and last decades longer in a South Shore moisture environment.
We also pay attention to where supply lines and drain cleanouts are located relative to your base flood elevation. Small decisions made during rough-in can make a future flood event far less damaging and far cheaper to recover from. Call 631-741-0199 to talk through the specifics of your Seaford property.






Plumbing, electrical, and structural work all require Town of Hempstead Building Department permits. A full bath remodel that touches the drain stack, adds a circuit, or moves walls requires permits. Simple cosmetic work — new fixtures, paint, mirrors — typically does not. We determine what is required during your free estimate visit and file on your behalf.
A typical full-bath renovation with tile, new fixtures, vanity, and updated plumbing and electrical runs in the $18,000 to $40,000 range on South Shore Nassau projects, depending on size and finish choices. A primary suite bath with a walk-in shower, soaking tub, and premium tile can go higher. A free written estimate from us gives you a firm number before anything is committed.
Yes, and it is one of the more common projects we do in Seaford. The feasibility depends on where your existing drain stack runs and whether the addition can tie in without a major excavation. We look at all of that during the estimate visit and design the most practical and cost-effective path to a second bath.
