You may know your baseboards as the crevice-creating trim that you always forget to clean. Or you may have never heard the ambiguous-sounding term before. Either way, baseboards are rarely thought about, let alone talked about. 

Let’s get the conversation started—what are baseboards, what kind of baseboards are in style, what materials are available, and how can you choose the best type for your home?

What Are Baseboards?

Baseboards, also known as skirting boards, base or floor molding, or mopboards, are the planks that line the lowest part of your interior walls, covering the space where the floors and walls intersect. Apart from being a visually-pleasing pop of trim that accents your wall color, baseboards add a layer of protection against bumps with the vacuum, scratches from pet paws, and kicks from regular foot traffic.

Baseboards also protect drywall from mop water, overturned drinks, and other spills that would otherwise cause moisture damage. They also provide a solid stopping point for dirt and debris. Plus, baseboards provide a functional and attractive cover for hardwood flooring where gaps accommodate natural expansion.

Different Styles of Baseboards

Variety is the spice of home improvement, and baseboards are surprisingly accommodating in that department. Whether you’re building from the ground up or simply remodeling, you have several different profiles to choose from.

Let’s look at what kind of baseboards are in style and what types of baseboard trim are available. With so many options, you may want to enlist the help of a local baseboard installation professional to make the right choice.

Rounded or Stepped Baseboards

The most popular baseboard style is a rounded or stepped baseboard, which is flat on the bottom with decorative grooves near the center and a rounded half-moon or step-shaped top that tapers into the wall. The look is simple and modern, with a short profile that isn’t too ornate or fussy.

Flat Baseboard Molding

As the name suggests, this baseboard style sports a completely flat profile. It comes in a range of height options, typically falling between 3 and 5 inches tall. The flat shape makes it versatile enough to suit any style of home decor and very easy to clean.

Sculpted Baseboard Trim

If you’re in the mood for something fancier, sculpted baseboard trim is the ideal pick. This baseboard profile features a variety of scalloped or stepped designs on top, moving down to a flat base at the bottom. It offers a wide array of height options, from mid-heights of around 4 to 5 inches to taller heights topping 7 inches or more. 

The ornamental shape of sculpted baseboard trim perfectly complements colonial-style homes, Victorian styles, and other decorative styles that focus on antique or ornate designs. However, the detailed designs tend to catch more dust, so cleaning your baseboards will be more difficult and time-consuming with this option.

Baseboard Options and Add-Ons

Once you’ve selected the ideal baseboards for your home, you have even more options to dress them up. You can also add heaters to your baseboards to make them next-level functional. Check out these accessories to make your baseboards work for your space.

Quarter Round Trim 

Quarter round trim is used in tandem with baseboards. It features a flat back and a front shaped like a perfect quarter-slice of a cylinder. The name “quarter round” derives from “one-quarter of a round dowel.” Its rounded shape sits at the bottom of the baseboard, standing in front of it to visually soften the edges.   

Shoe Molding

Shoe molding is in the same league as quarter round trim, but with a slightly different shape. Rather than being a perfect quarter of a cylinder, it is still curved but broader. Like quarter round trim, it’s meant to accent and soften the edges of baseboards.

Baseboard Heaters

If you’re working on updating an older home, baseboard heaters are a great solution when additional ductwork is out of the question (and out of the budget). Among the other baseboard heaters pros and cons are that they run quietly. However, some safety concerns exist, as you should keep anything flammable at least 12 inches from them.

Electric baseboard heaters cost an average of $780 to install, and they’re more DIY-friendly than other options.

Different Types of Baseboard Materials

Baseboards also come in a wide variety of material options. Each of these has its own pros and cons, so it’s important to consider that when choosing the right baseboard for your home.

Medium-Density Fiberboard (MDF)

Medium-density fiberboard, also known as MDF, is composed of wood, resin, fibers, and other materials. Since it boasts a more consistent texture than wood, manufacturers can sculpt it into a wide variety of shapes, from simplistic to ornate. Likewise, it’s extremely easy to cut, so it’s an excellent option for DIY baseboard installs in kitchens, living rooms, and bedrooms.

MDF also comes primed and ready to paint, which can be good or bad depending on your plans. This option is ideal for homeowners looking to cut their baseboard costs and planning to paint them anyway. However, homeowners looking to stain their baseboards will have to choose a different material.

Pine

Pine is another budget-friendly baseboard material that comes either primed or unprimed, giving you free rein to paint or stain. Quality pine is typically free of knots and other blemishes, but its inconsistent texture makes it more difficult to make a straight and splinter-free cut. There’s also a possibility of cracks or warping, so be sure to examine all pieces thoroughly before you buy. Keep in mind that wood materials are not an ideal baseboard material for bathrooms unless you plan to stain it thoroughly to reduce moisture build-up.

Hardwood

Hardwoods such as maple and oak are the priciest option for baseboard materials, but their quality and elegance make them worth the splurge. Costs vary based on the profile and the type of hardwood used. Like pine, these are also prone to warping—don’t forget to check your pieces before purchasing.

Choosing Your Baseboard Thickness

Different baseboard profiles offer different thicknesses. While it’s probably not a forethought in your baseboard journey, it’s still important to consider. Not just to be picky—still, by all means, do be picky with your baseboards—but also to complement the trim around your door (called the door casing). 

As a general rule, you want your baseboards to be slightly less thick than your door casing (around ⅛ of an inch difference at minimum). This thickness helps carve that pleasing distinction between your door trim and your baseboards. 

Here are the typical thickness options for these profiles:

  • Rounded or stepped: ⅝–⅞ inch

  • Flat: ⅝ inch

  • Sculpted: ⅝ inch–1 inch

Choosing Your Baseboard Color

Now that you’re a baseboard connoisseur, you have the option to play with color and become a baseboard trendsetter. Matching wood is a standby classic, as is white paint (albeit prone to scuffs and stains). Here are a few unexpected color options to consider.

Coordinating Color Schemes

If you’re wondering what color to paint your baseboards, start by looking at what color you’ll be painting the walls. Then, start looking at tertiary colors or varying tints and shades of the same hue. Of course, this is a jumping-off point—there are no rules in the realm of baseboards (except the one about door casing, of course). Grab some paint strips from your local hardware store and let your creativity run wild. 

Soft Grays

A soft gray trim brings an airy feel to a room, especially when paired with white walls. The look is refreshing and modern, pairing well with farmhouse style, minimalism, and any other clean, simplistic style of decor.

Stark Contrasts

If you can’t get enough of your outdoor space, painting both your baseboards and your window trim in a dark, contrasting color both highlights the windows and creates bold lines around the room for tons of visual interest. This concept works especially well as a striking complement to eye-catching wallpaper accents.

Frequently Asked Questions

Baseboards’ primary purpose is to protect the bottom of the wall from scuffs due to shoes, vacuums, and furniture. The baseboard covers any unsightly gap between the wall and floor where insects or rodents might find an entry point. From a stylistic point of view, it allows you to add a splash of color or a decorative design element because of the shape of or grooves in the wood or other material.

Trim refers to any type of covering in areas where walls meet items like ceilings, doors, windows, and floors. A baseboard is a specific type of trim that goes on the wall where it meets the floor. The baseboard is often wider than other types of trim, allowing it to provide protection in an area that may experience damage from shoes or moving furniture. The cost to install them is slightly different, too. Installing trim costs around $1,400, while the average cost to install baseboards is about $1,100.

Some people choose not to install baseboards, but it’s far more common to use them than to skip them. Some might choose not to install baseboards to save money or to enhance a minimalist design in a room. If you choose not to install baseboards, it’s essential to make sure the drywall or wainscoting installation fits tightly against the floor, which requires precise work.

Some people choose to install baseboards along stairs, but it can be a tricky job. Following the stairs’ angles requires making several cuts, including miter cuts. In a stairway with walls on either side, you’ll want to install baseboards on both sides, doubling the work. Many people rely on a pro for this job and pay $5 to $10 per linear foot to install baseboards on stairs, which is slightly more expensive than baseboard installations along the floor. The cost to install railings at the same time will add an average of about $900 to the job.
