Bathroom Remodel Addition Costs in Maryland | D & I Contractors

If you’re a homeowner in Baltimore or Potomac, Maryland, thinking about upgrading your bathroom, one of your first questions is usually the same — “How much will it cost?”

Bathrooms are among the most valuable rooms in your home, both for everyday comfort and long-term resale. But costs can vary widely depending on the size, design, and materials you choose. Whether you’re planning a simple bathroom remodel in Baltimore or adding an entirely new bathroom to your home in Potomac, MD, understanding the price ranges and what affects them is essential.

At D & I Contractors, we’ve helped hundreds of Maryland homeowners modernize and expand their bathrooms — from compact powder rooms to luxury master suites. In this guide, we’ll break down real-world costs, examples, and smart tips to help you plan your next bathroom project with confidence.

Understanding Bathroom Remodeling vs. Bathroom Addition

Before diving into the numbers, it helps to clarify the difference between a bathroom remodel and a bathroom addition.

• Bathroom Remodel: Updating an existing bathroom’s layout, finishes, and fixtures. Example: Replacing old tiles, installing a new vanity, and adding better lighting.

• Bathroom Addition: Building a brand-new bathroom in your home — either expanding existing space or adding a new room altogether.

Both increase comfort and home value, but their costs, timelines, and scope differ significantly.

Bathroom Remodel Cost in Baltimore, MD

How Much Does a Bathroom Remodel Cost in Baltimore?

The average bathroom remodel cost in Baltimore typically ranges between $9,000 and $28,000, depending on size, layout, and materials.

A small guest bathroom or powder room may be refreshed for around $8,500–$12,000, while a full master bathroom with new flooring, shower, vanity, and plumbing can easily reach $25,000–$35,000.

Here’s a quick look at average ranges based on bathroom size:

Type of Bathroom	Average Remodel Cost (Baltimore)
Half Bath / Powder Room	$8,000 – $12,000
Full Standard Bath	$13,000 – $20,000
Master Bath / Ensuite	$25,000 – $35,000+

These prices typically include demolition, plumbing updates, tiling, cabinetry, lighting, and paint.

What Influences the Cost of a Bathroom Remodel?

Every remodel is unique. Here are the biggest factors that affect your final price:

1. Material Selection – Tile type, countertop material, and fixture brand can significantly impact cost. Luxury tiles or quartz countertops cost more than ceramic and laminate options.

2. Plumbing Changes – Moving drains or rerouting pipes adds labor and materials.

3. Age of the Home – Older Baltimore homes often need updated plumbing or electrical systems.

4. Custom Features – Heated floors, walk-in showers, freestanding tubs, or double vanities all increase cost but also elevate comfort and resale value.

5. Labor Quality – Hiring licensed, experienced remodelers ensures your project is done safely and built to last.

Example: A homeowner in Charles Village remodeled a 5x8 bathroom using mid-range finishes — ceramic wall tile, new vanity, and LED lighting — for about $14,800. The result was a clean, modern look completed in three weeks.

How Much Does a Bathroom Addition Cost in Potomac?

If your home needs an entirely new bathroom, the investment is larger — but so is the value it brings.

The average bathroom addition cost in Potomac, MD ranges between $35,000 and $75,000, depending on size, plumbing location, and finishes. Potomac’s upscale housing market often drives higher-end upgrades, with homeowners opting for spa-style amenities like steam showers, heated floors, and stone tile.

Here’s a breakdown by type of addition:

Type of Bathroom Addition	Average Cost (Potomac, MD)
Half Bath (Powder Room)	$18,000 – $30,000
Full Bath Addition	$35,000 – $55,000
Luxury Master Ensuite	$60,000 – $85,000+

What Drives Bathroom Addition Costs in Maryland?

1. New Plumbing & Drainage Installation – If you’re adding a bathroom where none existed, new water and waste lines are required.

2. Structural Work – Framing, drywall, insulation, and waterproofing add up.

3. Electrical & Lighting – Installing GFCI outlets, vent fans, and modern lighting fixtures.

4. Permits & Inspections – Maryland and Montgomery County require permits for new additions.

5. High-End Finishes – Custom tile, rainfall showers, and built-in storage increase cost but enhance daily use.

Example: A homeowner in Potomac added a 120 sq. ft. master bathroom as part of a second-floor expansion. The project included marble tile, a freestanding tub, and a walk-in shower — completed by D & I Contractors for $68,500 in eight weeks. The result was a hotel-quality retreat with a resale value boost of nearly $80,000.
