Bathroom Remodeling in Gaithersburg, Maryland: Licensed Contractor 2026 Guide

Bathroom Remodeling in Gaithersburg, Maryland: What Homeowners Need to Know in 2026

Gaithersburg is one of the most architecturally diverse communities in Montgomery County — and that diversity creates bathroom renovation conditions that differ significantly from neighborhood to neighborhood. Gaithersburg spans everything from the historic Victorians of Olde Towne near the MARC station to the master-planned communities of Montgomery Village, Kentlands, and Lakelands — plus a huge stock of 1980s–2000s Colonials, split-foyers, townhomes, and condos. Many of these homes now have dated builder-grade bathrooms: oak vanities, cultured-marble tops, builder tile, and oversized garden tubs owners want reimagined as walk-in showers.

Because of this diversity, a contractor who understands Gaithersburg’s specific neighborhoods — and the permitting nuance that makes Gaithersburg distinct from every other Montgomery County community — brings knowledge to your bathroom renovation that no national cost guide or generic contractor can provide.

The most important thing a Gaithersburg homeowner can know before starting a bathroom renovation: Gaithersburg has two separate permitting authorities, and which one governs your project depends entirely on your specific address. Getting this wrong causes permit application rejection before construction can begin.

At H&C Construction Design Build, we are based in Rockville — five minutes from Gaithersburg — and serve Gaithersburg homeowners and all of Montgomery County with Bathroom Remodeling projects. Here is what Gaithersburg homeowners need to know before starting a bathroom renovation in 2026.

The Gaithersburg Permitting Reality — The Most Important Local Knowledge

This is the single most locally specific and practically important thing a Gaithersburg homeowner can know — and the one detail that most contractors serving Gaithersburg from outside the immediate area get wrong.

Gaithersburg spans everything from City of Gaithersburg and Montgomery County DPS permitting — and the line between these two authorities runs through the middle of the city.

Properties within the City of Gaithersburg’s corporate limits — which includes Olde Towne, the Kentlands, Lakelands, and large portions of the city’s developed core — are permitted through the City of Gaithersburg’s Department of Planning and Code Enforcement. The City of Gaithersburg has its own permit office, its own building inspectors, and its own review process that is separate from Montgomery County’s.

Properties in the Gaithersburg area outside the city’s incorporated limits — including many neighborhoods in North Gaithersburg, parts of Montgomery Village, and areas near Quince Orchard and Great Seneca Highway — are permitted through Montgomery County DPS in Wheaton.

A contractor who submits a bathroom permit application to the wrong authority — attempting to use Montgomery County DPS for a City of Gaithersburg property, or vice versa — receives an immediate rejection that resets the timeline. Confirming the correct permitting jurisdiction for your specific Gaithersburg address is the first step in every bathroom renovation we take on here.

Gaithersburg’s Neighborhoods — What Each Means for Bathroom Renovation

Kentlands and Lakelands

Kentlands is one of Maryland’s premier new urbanist communities — developed in the early 1990s with a mix of Colonial and craftsman homes designed to evoke historic small-town character. After 30+ years, Kentlands homes’ original bathrooms are showing their age. Builder-grade vanities, original cultured marble surrounds, and 1990s tile choices are the norm in homes that are otherwise well-maintained.

Kentlands homeowners are among Gaithersburg’s most renovation-active. The most common scope: a full primary bathroom gut renovation replacing the original fiberglass or cultured marble surround with a custom tile curbless walk-in shower, updating the vanity to a current specification, and adding frameless glass. This scope typically runs $35,000 to $65,000 at mid-range specification.

HOA considerations: Kentlands has an active homeowners association. For bathroom renovations affecting only the interior, HOA review is generally not required. However, any exterior change — including replacement of windows in the bathroom — requires Kentlands HOA approval before city permits are submitted.

Montgomery Village

Montgomery Village is one of Maryland’s largest planned communities — developed in the 1960s through 1980s with a wide range of housing types from garden apartments through townhomes and single-family homes. The older Montgomery Village housing stock has bathrooms from the 1970s and 1980s that are genuinely dated — not just aesthetically but functionally, with plumbing configurations, tile systems, and ventilation approaches that reflect a different era’s standards.

For Montgomery Village properties, confirming the correct permitting jurisdiction is especially important. Different sections of Montgomery Village may fall under City of Gaithersburg or Montgomery County DPS authority depending on their exact platted location.

Olde Towne Gaithersburg

Olde Towne is Gaithersburg’s historic district — a walkable Victorian neighborhood centered on Summit Avenue near the MARC station with homes dating to the late 1800s and early 1900s. Bathroom renovation in Olde Towne properties involves the same pre-1978 lead paint considerations that apply throughout Maryland’s older housing stock, plus the potential for historic district review for any exterior changes.

Interior bathroom renovations in Olde Towne — which includes everything that doesn’t affect the exterior envelope — typically bypass historic review. However, contractors working in Olde Towne homes should be familiar with the construction realities of Victorian-era plumbing systems and the specific conditions that 100-year-old houses present once walls are opened.

Crown Farm and Newer Gaithersburg Communities

Crown Farm, Washingtonian Center area, and other newer Gaithersburg communities feature homes from the 2000s and 2010s — in better baseline condition than older stock but with builder-grade finishes now reaching the 15 to 20 year renovation threshold. Primary bathroom renovations in these communities focus primarily on finish quality upgrade — replacing the original builder specification with curbless showers, double vanities, and quality tile.

What Bathroom Remodeling Costs in Gaithersburg in 2026

Gaithersburg bathroom renovation costs reflect Montgomery County’s premium labor market and the specific conditions of each neighborhood’s housing stock.

Powder room update: $6,000 to $14,000. New vanity, toilet, flooring, lighting, and paint. Quick scope, no shower work involved.

Secondary or hall bathroom (full renovation): $14,000 to $32,000. Complete tile replacement, new vanity, new toilet, updated GFCI electrical, and exhaust fan. In Kentlands’ 1990s-era homes and Montgomery Village’s older stock, a 15% contingency is standard for plumbing and subfloor discoveries.

Primary suite bathroom (comprehensive transformation): $32,000 to $65,000. Custom tile curbless walk-in shower replacing the original cultured marble or fiberglass surround, double vanity, frameless glass, updated lighting, and heated floor. This is the most consistently requested scope across all of Gaithersburg’s active renovation neighborhoods.

Luxury primary suite: $65,000 to $100,000+. Steam shower, natural stone, custom cabinetry vanity, freestanding soaking tub, radiant heat throughout. Common in Crown Farm’s higher-value properties and Kentlands’ most premium homes.

Permit fees. City of Gaithersburg bathroom permits for projects involving electrical and plumbing modifications run $400 to $1,200 depending on project value and scope. Montgomery County DPS permits for comparable scopes run $500 to $1,500.

Choosing a Bathroom Remodeling Contractor in Gaithersburg — The Non-Negotiables

MHIC license verification — always first. Every Maryland home improvement contractor must hold an active MHIC license. Verify at dllr.state.md.us before any design conversation. Since June 1, 2024, Maryland law requires minimum $500,000 general liability insurance. Request the certificate and verify it directly with the insurer.

Gaithersburg dual-jurisdiction permit knowledge. This is the single most important locally specific contractor qualification. Ask directly: “Do you know which permit authority governs my specific Gaithersburg address — City of Gaithersburg or Montgomery County DPS?” A contractor who doesn’t immediately understand this distinction has not worked regularly in Gaithersburg.

HOA knowledge for Kentlands and Lakelands. For renovation projects involving any exterior element, the contractor must be familiar with the Kentlands HOA architectural review process. Interior-only bathroom renovations in Kentlands typically bypass HOA review — but confirm this for your specific property and scope before finalizing design.

Pre-1978 lead paint certification. For Gaithersburg homes built before 1978 — which includes all of Olde Towne and much of Montgomery Village’s older stock — EPA Lead RRP certification is required for all contractors working in these homes. Verify current certification.

References from Gaithersburg neighborhoods. Ask for completed bathroom projects specifically in Kentlands, Montgomery Village, or comparable Gaithersburg communities from the past 24 months. The differences between an Olde Towne Victorian, a Kentlands Colonial, and a Montgomery Village garden townhome are real and meaningful for bathroom renovation planning.
