Homeowners in St. Louis, MO, planning to paint a room will find costs comparable to national averages, though local labor rates and market demand can influence the final price. The cost to paint a room in St. Louis, MO, ranges between $380 and $1,522, with an average cost of $1,046.

Many factors affect the price, such as the room’s square footage, ceiling height, and the current condition of the walls. Labor in the St. Louis, MO, area can also play a significant role in pricing. Additionally, opting for higher-end paints or custom finishes may increase costs but can enhance durability and appearance.

Interior Painting Cost Factors 

The price you’ll pay for painting a room in St. Louis, MO, depends on several key factors, including the type of room, the square footage, and whether baseboards or trim are included. Let’s take a more detailed look at how these affect the cost.

Room Size

Professional interior paint jobs are priced at $2 to $5 per square foot. The larger the room, the higher the cost. If you know the square footage of your room, you can use these numbers to get a fairly accurate estimate for your paint job.

Room Height

Another cost factor to consider when painting a room is its ceiling height. If you have high or difficult-to-reach ceilings, you can expect to pay an additional fee for labor and materials. Painting a ceiling costs an extra $1 to $5 per square foot, depending on the ceiling type and the painter’s rates.

You’ll pay the most for cathedral ceilings that reach above 12 feet, while a 10-foot ceiling will only add $1 per square foot to paint since they don’t require any scaffolding or special equipment.

Room Type

The price of your painting project depends on the room type. Bathrooms are the smallest rooms in the house and the least expensive to paint, while painting living rooms is the most costly. Keep in mind that some larger rooms, like kitchens, can be inexpensive to paint because a large portion of the walls is covered by cabinets or backsplashes.

Baseboard and Trim

Want to refresh your trim and baseboard paint? Giving your home accents like trim, baseboards, crown molding, and windows a fresh coat of paint will cost $1 to $3 per linear foot.

Keep in mind that professional painters often charge extra for hard-to-reach accents—up to an additional $6 per linear foot. Particularly ornate trim can also be a bit more expensive to paint if there are a lot of nooks and crannies your professional will have to cover.

Paint Type

On average, you’ll pay $18 to $60 per gallon, and each gallon of paint covers between 300 and 400 square feet. You can get a budget-friendly option from a big-box retailer for as little as $10 per gallon or spend more than $90 per gallon on a designer brand or rare pigment.

Overall, oil-based paints cost slightly more than latex-based paints (though latex is by far the most popular for indoor use). 

Paint Finish

On top of that, you’ll pay more for paint with a glossier finish. Paint durability and moisture resistance also increase as the finish gets glossier, so consider the area you’re painting and don’t shop solely on cost. 

Accent or Textured Walls

Wall texture can transform the feel of a room—whether it’s a combed finish, sand swirl, or orange peel texture. It’s not everyone’s cup of tea, though some homeowners love it. Expect to spend a couple of dollars extra per square foot if you want to add or remove wall texture before the painting process:

•  The cost of texturing your walls is $1 to $3 per square foot.

•  The cost of skim coating drywall to remove texture is $1 to $2 per square foot.

Wall Repairs 

You may need to repair your walls before you can paint them, especially if you have water damage or cracked or peeling paint. The cost of drywall repair falls between $275 and $850.

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.
