Bathroom Addition Cost Factors 

The cost to add a bathroom in Denver, CO, is determined by several key factors, such as the type of bathroom, its location, and the materials you select. Here’s a breakdown of how these shape the project price.

Type of Bathroom 

The type of bathroom you add should be based on its location in your home and your budget. Full and primary bathrooms are more common in primary bedrooms and on second floors, while you might opt for a half bath near a first-floor guest room.

• Half: A half bath has two of four major bathroom fixtures, such as a sink and toilet, and ranges from $5,500 to $15,000 for a 15- to 25-square-foot space. You could spend as little as $4,000 for a basic conversion or as much as $18,000 for a brand-new powder room with designer fixtures.

• Three-quarter: Expect to pay $8,500 to $28,000 to add a three-quarter bathroom that’s 25 to 40 square feet. This bathroom has a toilet, sink, and shower. You could spend as little as $6,500 if there’s existing plumbing or as much as $32,000 for a luxury bathroom addition.

• Full: A full bathroom costs $13,000 to $58,000, ranges from 40 to 100 square feet, and has a sink, toilet, shower, and bathtub. Larger layouts include built-in cabinetry or a linen closet.

• Primary: A primary bathroom addition costs $27,000 to $100,000 and connects to the primary bedroom. You can spend as little as $22,000 on a basic conversion or more than $120,000 on high-end fixtures like a freestanding tub and a luxury walk-in shower.

• Jack and Jill: A Jack and Jill bathroom costs $30,000 to $110,000, 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 $9,000 to $26,000, but you could spend up to $36,000 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 significantly influences the cost. A bathroom conversion costs $260 to $340 per square foot, whereas a bathroom addition costs $475 to $700 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

Materials

Materials make up 40% of the project cost, so the choices you make will be significant. A bathroom addition built with midrange materials costs an average of $62,000, while an upscale bathroom addition costs an average of $110,000. 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 between cost, durability, and style, making them a popular choice for most bathroom additions. They provide a clean, modern look with reliable performance without the higher price tag of luxury finishes, and require standard maintenance that’s manageable for most homeowners.

• 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.

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.
