Design-Build Bathroom Remodeling
Bathroom Remodeling in Montgomery County, MD
AC Remodeling is a design-build bathroom remodeling contractor in Montgomery County, based in Gaithersburg and serving Rockville, Bethesda, Potomac, Chevy Chase and Northwest DC. We work with homeowners planning a full primary bath or hall bath renovation, designed, waterproofed and built by one team.
Why Waterproofing Decides How Long a Bathroom Remodel Lasts
A bathroom hides its quality behind the tile. A gap in the waterproofing rarely shows up on day one. It shows up a year or two later as a stained ceiling below, loose tile or mold behind the wall, and by then the only fix is tearing the shower out.
That is why we waterproof every shower to code with a complete membrane system before any tile is set. We also level every wall and floor plane, so large-format tile lands flat and the grout lines stay straight.
You approve a photo-real 3D rendering and a detailed proposal before demolition. Then one project manager and one crew see it through to completion.

What's included
Bathroom Features We Build Into Every Remodel
Waterproofing built to code
A complete waterproofing membrane system behind every shower, installed before tile, for a shower that is built to last.
Aging-in-place design
Low-threshold showers, comfort-height fixtures, and blocking for grab bars built into the walls now, even if you don't need bars yet. Adding blocking later means opening the finished tile, so we plan for it up front.
Layered lighting design
Backlit mirrors, niche LEDs and dimmable recessed lighting, specified room by room.
Large-format tile expertise
Slab-look porcelain installed with minimal grout lines. Large tiles need a much flatter substrate than standard tile, because any dip or hump shows up as uneven edges. That is why we level every surface before the tile goes down.
Investment
What a Bathroom Remodel Costs in Montgomery County
These ranges reflect our recent Montgomery County bathroom projects:
- Hall bath, existing layout$40,000 to $60,000
- Primary bath, full remodel$90,000 to $150,000
- Primary bath with layout changes or tub-to-shower conversion$110,000 and up
Where a project lands in those ranges depends mostly on the cabinets and fixtures, especially when the design includes a tub and tub filler, and on the labor involved in relocating plumbing or replacing old cast iron drain lines. Older bathrooms that need new water lines and wiring sit at the higher end. We share your investment range in the first conversation.
Permits
Bathroom Permits in Montgomery County, Rockville and DC
Most full bathroom remodels need building and electrical permits, and plumbing changes need their own approval:
- Most of Montgomery County: Montgomery County Department of Permitting Services
- Rockville and Gaithersburg: each city's own permit office
- Plumbing in Maryland: WSSC Water
- Northwest DC: the DC Department of Buildings, including plumbing
Inspections happen before walls and floors are closed, and scheduling them on time is the key to keeping a bathroom remodel on track. We build every inspection into the timeline from day one.
Condos
Condo Bathroom Remodels in Rockville
Condo bathrooms come with rules a single-family home doesn't have. On our condo bathroom remodel in Rockville, the building administration required a certificate of insurance, a licensed contractor, set work hours, elevator reservations and specific rules for hauling away debris. If a unit's shutoff valves aren't inside the unit, the building also needs notice before the water is shut off. We confirm these requirements with your building and build them into the schedule before demolition.

FAQs
Bathroom Remodeling FAQs
How long does a bathroom remodel take?
Active construction runs about 2.5 weeks for a hall bath and 4 to 6 weeks for a primary bath. The full project takes 7 to 14 weeks including design and permitting. A full gut with plumbing or layout changes sits at the longer end. You get a detailed schedule before construction begins.
Do I need permits for a bathroom remodel in Montgomery County?
Yes. Most full remodels need building and electrical permits from Montgomery County or your city (Rockville and Gaithersburg run their own), and plumbing changes in Maryland go through WSSC Water. DC projects are permitted through the DC Department of Buildings. We manage applications, scheduling and inspections.
Can we use the bathroom during construction?
If you have more than one bathroom, most homeowners use the others without issue. For single-bathroom homes, we plan around the disruption and keep the schedule tight. Dust control and daily cleanup protect the rest of your home.
Does AC Remodeling take on partial bathroom projects?
No. We focus on full-scope design-build bathroom remodels, not cosmetic updates like vanity swaps or shower repairs. Handling the whole project lets us control the waterproofing and quality from demolition to final tile.
