Bathroom Addition Cost Factors 

When budgeting for a bathroom addition in Columbus, OH, you’ll need to consider your bathroom size, location, and type. Features, appliances, and material choices will also impact your total.

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 $3,800 to $11,500 for a 15- to 25-square-foot space. You could spend as little as $2,900 for a basic conversion or as much as $14,300 for a brand-new powder room with designer fixtures.

• Three-quarter bathroom: Expect to pay $5,700 to $21,000 to add a three-quarter bathroom that’s around 25 to 40 square feet. This bathroom has a toilet, sink, and shower. You could spend as little as $3,800 if there’s existing plumbing or as much as $23,900 for a luxury bathroom addition.

• Full bathroom: A full bathroom costs $9,600 to $47,800, 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 $21,000 to $86,000 and connects to the primary bedroom. You can spend as little as $14,300 on a basic conversion or more than $95,500 on high-end fixtures like a freestanding tub and a luxury walk-in shower.

• Jack and Jill bathroom: A Jack and Jill bathroom costs $23,900 to $95,500, 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 $5,700 to $19,100, but you could spend up to $28,700 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 $190 to $240 per square foot, whereas a bathroom addition costs $380 to $530 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 $9,600, for example, and bathroom vanities can cost anywhere from $480 to $3,800. 

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 $56,300, while an upscale bathroom addition costs an average of $102,700. 

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 offer a balance of durability, style, and affordability. Options like quartz, porcelain, and name-brand fixtures give your bathroom a polished look without the premium price. 

• 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 makes up a significant portion of your bathroom addition costs. When hiring a Columbus, OH, bathroom remodeler, you’ll need to factor local labor costs, permit fees, and any additional pros into your budget.

Labor 

Bathroom remodelers in Columbus, OH, charge $50 to $145 per hour, depending on your project size and scope. You’ll see higher rates for a primary or Jack and Jill bath compared to a half bath, since larger projects require more plumbing, tile work, and fixture installations. When comparing quotes, always confirm that your pro carries current licensing and insurance. 

Permits

The City of Columbus requires a permit for most bathroom remodels and additions. If your project involves plumbing, electrical, or structural work, budget an additional $350 for permit and inspection fees. Your contractor will often pull the permits and schedule inspections for you, so confirm they’re included in your quote.

Additional Pros to Consider Hiring 

Remodeling or building a bathroom is a big job, and bathroom remodelers often subcontract parts of the job to other specialists, including:

• 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 $960 to $9,600.

• Electrical: The cost of getting your electrical in place varies based on whether you’re using existing wiring or if your pro will need to install everything themselves. Electrical work for a new bathroom can cost $480 to $2,400. 

• General contractor: Larger additions may require a general contractor to coordinate trades, schedule, and permits. These pros generally charge 10% to 20% of the total project cost.

Does Adding a Bathroom Increase Home Value?

Adding a bathroom offers a 30% to 50% return on investment (ROI) for Columbus, OH, homeowners. Much of the city’s older housing stock was built with just one full bathroom, making an addition an attractive selling point for local buyers. Building a new bathroom boosts the functionality, aesthetics, and efficiency of your home, helping it stand out in the resale market.

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.
