Bathroom Remodel – Lambertville, NJ
This is one of the most material-specific projects in the portfolio. The floor is MSI Greecian White polished marble mosaic. The shower walls are MSI Cienega Springs stone and glass mosaic, installed from floor to ceiling. There is also a new partition wall built to separate the bathroom from an adjacent closet, PVC wainscoting along the lower walls, and a double vanity with two medicine cabinets. All of it in 40 square feet, completed in 3 weeks.
Lambertville is a small historic city in Hunterdon County, NJ, along the Delaware River. The homes here tend toward older construction — Victorian-era rowhouses and 19th-century residential buildings — which often means bathrooms that have not been updated in decades and layouts that no longer make sense. This project on N Union Street reflected that context.

The Tile Selection
The two tile choices here are what give this bathroom its character. MSI Greecian White polished marble mosaic on the floor brings a bright, reflective quality to a 40-square-foot space — polished marble mosaic at floor level catches light in a way that flat ceramic does not, and the small-format mosaic pieces provide more grout lines underfoot for traction. The floor choice alone makes the room feel different from a standard tile installation.
On the shower walls, MSI Cienega Springs stone and glass mosaic takes a different approach. Stone and glass mosaic tile has a layered visual texture — the glass pieces reflect light differently from the stone pieces, creating depth in the wall surface rather than a flat finish. Running it from the floor to the ceiling of the shower maximizes that effect and eliminates any transition between the tiled shower wall and any other surface above it. The combination of the marble mosaic floor and the stone-and-glass shower walls gives this bathroom a finish quality that is unusual for a 40-square-foot space at this price point.
The Partition Wall
As with the Philadelphia project in this batch, a partition wall was built to separate the bathroom from an adjacent closet. The existing bathroom and closet shared a wall boundary that was not clearly defined — building the partition established a proper separation, added privacy, and gave both the bathroom and the closet a finished boundary wall. Framing, drywall, electrical wiring, and a new interior door with casings were all part of the partition work.
New outlets and switches were installed as part of the electrical phase, including a GFCI outlet above the vanity. In a Hunterdon County historic structure, bringing the electrical up to current code during a bathroom remodel is often more involved than it would be in newer construction.
Double Vanity with Medicine Cabinets in 40 Square Feet
Fitting a double-sink vanity into a 40-square-foot bathroom is a layout commitment. It works here because the homeowner supplied the vanity and because the cabinet dimensions were matched to what the room could accommodate without blocking the door or the tub access. Two medicine cabinets were mounted above — one on each side — each with a flanking light fixture. The divided storage and distributed lighting logic is the same as in other pages in this batch: two users, two storage areas, lighting that covers both halves of the vanity surface.
PVC Wainscoting and Finishing Details
White PVC wainscoting was installed along the lower section of the bathroom walls. PVC wainscoting is a practical choice in a bathroom — it provides a finished, architectural wall treatment that does not absorb moisture the way wood wainscoting would, and it is easier to maintain in a high-humidity environment. It adds a layer of visual structure to the lower walls without the maintenance requirements of painted drywall at floor level, where splashes and cleaning are most frequent.
A polished engineered marble threshold was set at the door jamb. Stainless steel accessories were installed throughout. The room was painted fully — walls, interior door, and all trim — and baseboards were installed to complete the finish.
What Three Weeks Look Like
The project was completed in three weeks. For a 40-square-foot bathroom that included a partition wall built, premium mosaic tile on both the floor and shower walls, a double vanity installed, electrical rough-in, and full paint and trim, three weeks represents a well-sequenced job. Mosaic tile, in particular, is more time-intensive to install than large-format tile — each sheet requires careful alignment, and the grout work has finer joints to manage. Getting all of that done cleanly in three weeks is a useful data point for anyone planning a similar project.
Bathroom Remodeling in Lambertville and the Surrounding Area
Lambertville sits in Hunterdon County, NJ, directly across the Delaware River from New Hope, PA. Its housing stock is predominantly older — many properties dating to the late 1800s and early 1900s — which means bathroom layouts and plumbing configurations that were never designed around modern fixtures or current code. A full remodel that addresses the substrate, the plumbing, the electrical, and the finishes properly is the right approach in this kind of building.

Considering a Similar Project?
Bathroom remodels in the 40-square-foot range that include premium mosaic tile, a partition wall build, a double vanity, and a full electrical rough-in in older NJ construction typically fall in the $9,000–$12,000 range. This Lambertville project came in at $9,600, completed in 3 weeks in May 2025. To discuss what your bathroom would involve, request a free estimate.
