Bathroom Addition Cost Factors 

Adding a new bathroom to your Baltimore, MD, home? When budgeting, you’ll need to consider the type, size, and location of the bathroom. Your features, appliances, and material choices will also impact total costs.

Type of Bathroom 

You’ll want to plan the type of bathroom addition based on its location in your home and your budget. Full and primary bathrooms are more common in primary bedrooms and on the second floor, while you might opt for a half bath in a first-floor guest bathroom. 

Here’s a breakdown of the average costs to add different types of bathrooms:

• Half bath: A half bath has two of four major bathroom fixtures (typically a sink and toilet), and ranges from $4,200 to $12,500 for a 15 to 25-square-foot space. You could spend as little as $3,150 for a basic conversion or as much as $15,700 for a brand-new powder room with designer fixtures.

• Three-quarter bathroom: Expect to pay $6,300 to $23,000 to add a three-quarter bathroom that’s around 25–40 square feet. This bathroom has a toilet, sink, and shower. You could spend as little as $4,200 if there’s existing plumbing or as much as $26,100 for a luxury bathroom addition.

• Full bathroom: A full bathroom costs $10,500 to $52,300, ranges from 40 to 100 square feet, and has a sink, toilet, shower, and bathtub. Larger layouts include a built-in cabinet or linen closet.

• Primary bathroom: A primary bathroom addition costs $23,000 to $94,000 and connects to the primary bedroom. You can spend as little as $15,700 on a basic conversion or more than $104,500 on high-end fixtures like a freestanding tub and a luxury walk-in shower.

• Jack and Jill bathroom: A Jack and Jill bathroom costs $26,100 to $104,500, depending on the fixtures and scale. These bathrooms connect two bedrooms or one bedroom to a hallway. Depending on the design, they measure 100 to 200 square feet and often have two sinks and an enclosed toilet. 

• Wet room: The average cost to add a wet room is $6,300 to $20,900, but you could spend up to $31,400 on a luxury design. Wet rooms are about the same size as a three-quarter bathroom, but costs can run higher for waterproofing the entire space and grading for drainage. 

Bathroom Size

Your bathroom’s square footage majorly influences the cost. A bathroom conversion costs $210 to $260 per square foot, whereas a bathroom addition costs $420 to $575 per square foot. 

Here’s a breakdown of the estimated costs to add a bathroom based on size:

Bathroom Location

Where you build a new bathroom will impact its final cost. Here are the average prices to add a bathroom, based on its location in your home. 

Features and Fixtures

If you want your bathroom to have premium features, you'll pay extra. A jetted tub can cost around $10,500, for example, and vanities can cost anywhere from $520 to $4,200. 

We cover different bathroom features below so you know how much to budget for your specific project:

Materials

Materials make up about 45% of the total project cost, so the choices you make will be significant. A bathroom addition built with midrange materials costs an average of $61,700, while an upscale bathroom addition costs an average of $112,300. 

Here are some of the major cost considerations based on material quality to keep in mind:

• Luxury materials: Luxury materials can help you emulate the feel of a bathroom at a five-star hotel and last longer, but expect to pay more for spa-like features. Research the maintenance needs for materials like marble, which require more effort to clean. 

• Midrange: Midrange materials like porcelain tile, quartz countertops, and fixtures from established brands offer durability and design without high-end costs. They’ll hold up well to daily use and are available in a wide range of styles for every aesthetic.

• Budget materials: Budget materials can help you save while still bringing your vision to life. Many cost-effective surfaces, like tile, are easier to clean than luxury alternatives. However, remember that the lowest-end materials aren’t as durable.

Bathroom Remodeling Pro Costs

Labor typically accounts for 40% to 60% of your total bathroom remodeling costs in Baltimore, MD. When budgeting for hiring a Baltimore, MD, bathroom remodeler, you’ll need to account for local labor rates, permits, and the cost of hiring additional pros. 

Labor 

Baltimore, MD, bathroom remodeling companies charge $50 to $100 per hour on average. Their rate depends on your project scope and complexity, with labor costs for a Jack-and-Jill bathroom far higher than for a half bath. 

When comparing quotes, confirm that your pro holds the proper insurance and licensing. Tipping isn’t required, but it is a thoughtful gesture if the pro goes above and beyond.

Permits

Permits are required for most bathroom remodels in Baltimore, MD. If your project involves plumbing, electrical, or structural changes, budget $100 to $200 for permits and inspections. Most contractors will handle the permitting process and bundle permit costs into your overall estimate.

Additional Pros to Consider Hiring

Building or adding a bathroom is a big job, and bathroom remodelers often subcontract other pros for work like plumbing and electrical. The most common specialists you’ll need for your project include:

• Plumbing: Plumbing is a significant cost when adding a bathroom. The farther your new bathroom is from existing plumbing, the more it will cost. Plus, you might need a new septic tank, depending on its current capacity and local requirements. On average, expect plumbing to cost $1,050 to $10,500.

• Electrical: The cost of getting your electrical in place varies based on whether you’re using existing wiring or your pro needs to install everything themselves. Electrical work for a new bathroom can cost $520 to $2,600. 

• General contractor: Large projects may require a general contractor to coordinate trades, schedules, and permits. They often charge 10% to 20% of the total project cost.

Does Adding a Bathroom Increase Home Value?

Adding a bathroom offers a strong return on investment in Baltimore, MD, with many homeowners recouping 30% to 50% of their total costs. Many of the city’s older rowhouses only include one full bath, so adding another can improve convenience, functionality, and buyer interest. Additional bathrooms can attract more buyers in the city’s competitive resale market and increase your resale value.

How Angi Gets Its Local Cost Data 

To help homeowners plan their next project, Angi provides readers with carefully researched cost data and upholds strict editorial standards. We start with national average project costs, which we collect by analyzing competitor information, retailer material costs, and input from professional contractors. We then apply local price index data to calculate location-specific estimates that reflect what homeowners typically pay in their local area. To do that, we use data from the U.S. Bureau of Economic Analysis (BEA), including its Regional Price Parities (RPPs), which measure price differences across cities. This helps us account for differences in labor, materials, and overall cost of living, so estimates in higher- or lower-cost areas better reflect real-world local pricing.

Every estimate undergoes a thorough editorial review to verify accuracy, consistency, and alignment with observed market conditions.
