Serving Smithtown
Bathroom renovations built for the way Smithtown homes are actually built.
Smithtown and the surrounding hamlets (Kings Park, Nesconset, St. James, Hauppauge) have a mix of 1960s splits, 1970s ranches, and newer builds. We work across all of them. The biggest local pattern: aging-in-place renovations for homeowners who've been in the house 30+ years and want to stay.
Our accessible bathroom specialty shows up a lot here. Curbless showers, reinforced grab bar blocking, comfort-height toilets, wider doorways. We design these so they look like high-end master baths, not institutional retrofits.
Suffolk County permits, Schluter-Certified waterproofing, one dedicated crew. Most Smithtown projects finish in 4–5 weeks.

What we've learned in Smithtown
Local details that matter.
Aging-in-place is the dominant request
A huge share of Smithtown bathrooms we renovate are specifically planned for long-term stay-in-place. We include design details like 36" doorways, curbless showers, grab bar blocking everywhere — even when the client isn't using grab bars today.
Septic system friendly specs
Much of Smithtown runs on septic. We use low-flow fixtures (1.28 gpf toilets, 1.75 gpm showerheads) that reduce septic load without sacrificing performance. Good for the system, good for the water bill.
Suffolk permit turnaround
Suffolk building department in Hauppauge processes Smithtown permits on a predictable schedule. We submit day-one and are rough-inspection-ready within two weeks.
Large lots = material staging
Smithtown lots tend to be larger — we can stage material and set up a proper work zone without crowding neighbors. Makes the demo and rebuild sequence smoother and cheaper.
