DIY Cardboard Fireplace

Materials and Tools

To build your own cardboard fireplace, you will need the following materials and tools:

Cardboard sheets

Start by gathering a few sheets of cardboard. You can find cardboard sheets at packaging stores, or even reuse old cardboard boxes for this project. Make sure the cardboard sheets are clean and in good condition.

Box cutter or utility knife

A box cutter or utility knife will be essential for cutting the cardboard sheets into the desired shapes. Make sure to handle the knife with caution and take necessary safety precautions.


A ruler will help you measure the dimensions for cutting the cardboard sheets accurately. This will ensure that your fireplace has proportionate panels and a balanced structure.


Use a pencil to mark the measurements and outlines on the cardboard sheets. This will make it easier for you to follow the design and cut precisely.

Hot glue gun

A hot glue gun is perfect for joining the cardboard panels together securely. It provides a strong bond and dries quickly, allowing you to assemble the fireplace efficiently.


A paintbrush will come in handy later on when it’s time to add the finishing touches to your cardboard fireplace. It will help you apply paint or markers smoothly and evenly.

Paint or markers

Lastly, you’ll need paint or markers to add color and decorative details to your fireplace. Choose colors that complement your desired design and style.

Creating the Basic Structure

Now that you have gathered all the necessary materials and tools, it’s time to start building the basic structure of your cardboard fireplace. Follow these steps to create a sturdy and reliable foundation for your DIY project:

Measure and cut the cardboard sheets

Begin by measuring and cutting the cardboard sheets to the appropriate sizes for each panel of the fireplace. Use your ruler and pencil to mark the measurements accurately, and then cut along the lines using a box cutter or utility knife.

Create the back panel

Take one of the cardboard sheets and cut it to your desired height and width for the back panel of the fireplace. This panel will serve as the main support for the entire structure.

Create the side and top panels

Next, cut two more cardboard sheets to create the side panels of the fireplace. These panels should be the same height as the back panel and slightly shorter in width, as they will connect to the edges of the back panel. Additionally, cut another cardboard sheet to create the top panel, which will cover the fireplace and add stability to the structure.

Join the panels together

Using a hot glue gun, carefully attach the side panels to the edges of the back panel. Apply a thin line of hot glue along the edges and press the panels firmly into place. Once the side panels are securely attached, repeat the process to attach the top panel to the sides and the back panel.

Reinforce the corners

To ensure the stability of your cardboard fireplace, reinforce the corners where the panels meet. Cut small pieces of cardboard and glue them to the inside corners of the fireplace. This reinforcement will prevent the panels from bending or collapsing.

Create the bottom panel

To complete the basic structure of your cardboard fireplace, cut another cardboard sheet to create the bottom panel. This panel should be the same size as the back panel and fit snugly into the bottom of the structure. Attach it using hot glue, making sure it is securely in place.

Designing the Fireplace Exterior

Now that you have created the basic structure, it’s time to design the exterior of your cardboard fireplace. Follow these steps to bring your fireplace to life with a custom design:

Choose a design

Before sketching the design on your cardboard, take some time to think about the style and theme you want for your fireplace. You can choose a traditional brick design, a modern minimalist look, or even a whimsical pattern. The design options are endless!

Sketch the design on the cardboard

Using a pencil, carefully sketch the chosen design on your cardboard panels. Start with the back panel and then move on to the side and top panels. This will help you visualize how the design will look once it’s cut out and painted.

Cut out the design

Once you are satisfied with the sketched design, use a box cutter or utility knife to cut out the shapes from the cardboard. Take your time and make precise cuts, following the outlines you made earlier. Be careful not to cut yourself during this process.

Add details with paint or markers

With the design cut out, it’s time to add details and colors to your fireplace. Use paint or markers to decorate the cardboard panels according to your desired style. You can paint bricks, add faux wood grain, or even create a stone texture. Let your creativity run wild!

Adding a Faux Fire

To make your cardboard fireplace even more realistic and cozy, you can add a faux fire. Here’s how:

Creating the firebox

Start by creating a firebox to hold the faux fire. Cut another cardboard sheet into a rectangular shape that fits inside the fireplace structure. This will serve as the base for the firebox.

Cutting out the logs and flames

Using the same cardboard, cut out logs and flames. The logs should be cylindrical, while the flames can have a wavy or triangular shape. Cut as many logs and flames as you desire based on the size of your firebox.

Paint the logs and flames

Now, take your paintbrush and add color and texture to the logs and flames. Use brown and black paint to create a wood-like appearance on the logs, and use shades of orange and yellow for realistic flames.

Arrange the logs and flames in the firebox

Once the paint has dried, arrange the logs and flames inside the firebox. You can stack the logs on top of each other and position the flames in between for a natural-looking fire. Play around with different configurations until you find the one you like best.

Attach LED lights for a glowing effect

To create a realistic fire effect, attach LED lights to the back of the flames. You can use small battery-powered LED lights with a flickering or color-changing feature. Secure the lights to the back of the flames using hot glue or transparent tape.

Enhancing the Realism

To make your cardboard fireplace even more realistic, you can add a few extra touches:

Add bricks or stones to the exterior

If you want your fireplace to have a textured appearance, consider adding bricks or stones to the exterior. You can cut small rectangular shapes from cardboard, paint them to resemble bricks or stones, and then glue them to the fireplace structure.

Paint or color the bricks or stones

To make the bricks or stones look more authentic, paint or color them using various shades of brown, gray, or red. You can create a weathered or aged effect by adding darker tones or distressing the painted surface with sandpaper.

Attach a mantel shelf or decorative trim

To complete the look of your fireplace, consider attaching a mantel shelf or decorative trim to the top panel. You can use a separate piece of cardboard or even repurpose a wooden plank for this. Paint or stain it to match the rest of the fireplace, and then secure it in place using hot glue.

Add a mirror for a reflective fire

For an extra touch of realism, you can attach a small mirror at the back of the firebox. This mirror will reflect the flames, creating the illusion of depth and enhancing the overall visual effect of your faux fire.

Safety Precautions

While cardboard fireplaces can provide a cozy and budget-friendly alternative to real fireplaces, it’s important to keep in mind certain safety precautions:

Keep the fireplace away from flammable materials

When setting up your cardboard fireplace, ensure that it is placed at a safe distance from any flammable materials such as curtains, furniture, or carpets. This will prevent any potential fire hazards.

Do not place real flames or hot objects inside

Remember that your cardboard fireplace is purely decorative and should not be used to contain real flames or hot objects. Using candles, matches, or any type of open flame inside the structure can be extremely dangerous and can potentially lead to a fire.

Ensure stability to prevent tipping over

To avoid accidents, make sure your cardboard fireplace is stable and securely constructed. Reinforce the corners and bottom panels as mentioned earlier to prevent tipping over. It’s always better to be safe than sorry.

Avoid using near children or pets unsupervised

If you have children or pets in your home, it’s important to keep them away from the cardboard fireplace, especially when it is unattended. The structure can be fragile, and accidental bumps or knocks could potentially cause harm to the little ones or your furry friends.

Alternative Cardboard Fireplace Options

If you’re not up for building your own cardboard fireplace from scratch, there are alternative options available that can save you time and effort:

Cardboard fireplace kits

Cardboard fireplace kits come with pre-cut pieces and instructions, allowing you to assemble your fireplace more easily. These kits often include designs, paints, and even LED lights for a more authentic look. They are a convenient option for those who want to skip the measuring and cutting steps.

Cardboard fireplace inserts

Cardboard fireplace inserts are designed to fit into existing fireplace mantels or surrounds. They provide the illusion of a real fire and can be easily installed or removed as desired. These inserts often come with customizable features, allowing you to create a personalized look.

Cardboard fireplace covers

If you already have a non-functioning fireplace in your home, you can use a cardboard fireplace cover to transform it into a decorative piece. These covers fit over the existing firebox and can be painted or decorated to match your style. They are a great option for those who want a temporary fireplace solution.

Cost and Sustainability Benefits

Building a cardboard fireplace comes with several cost and sustainability benefits:

Affordability compared to real fireplaces

Cardboard fireplaces are much more affordable than traditional fireplaces. Building your own allows you to save on the costs of materials and labor. You can create a beautiful and cozy ambiance without breaking the bank.

No need for chimney or gas/power supply

Unlike real fireplaces, cardboard fireplaces do not require a chimney or a gas/power supply. This means you can enjoy the warmth and ambiance without the additional expenses and maintenance that come with traditional fireplaces.

Recyclable and environmentally friendly

Cardboard is a recyclable and environmentally friendly material. When your cardboard fireplace has reached the end of its use, you can easily recycle it and contribute to waste reduction. Building a cardboard fireplace allows you to enjoy a cozy ambiance while being kind to the environment.

Other Creative Uses for Cardboard Fireplaces

Apart from adding warmth and charm to your space, cardboard fireplaces have other creative uses:

Holiday decoration

During the holiday season, a cardboard fireplace can become a focal point for seasonal decorations. Hang stockings, place presents, or even create a Santa Claus display on the mantel. It adds a festive touch to your home without the need for a real fireplace.

Stage or photo prop

Cardboard fireplaces make excellent props for stages or photo shoots. Whether you’re directing a play, hosting a themed party, or capturing memorable moments, a cardboard fireplace can serve as a backdrop or a centerpiece. It adds a touch of realism and enhances any scene.

Functional storage unit

If you’re in need of additional storage, a well-designed cardboard fireplace can double as a functional storage unit. Attach shelves or compartments to the structure to store books, candles, or other small items. This way, your fireplace becomes not just a decorative piece but also a practical storage solution.


Building your own cardboard fireplace is an exciting and cost-effective way to add warmth and charm to your living space. With just a few materials and tools, you can create a custom-designed fireplace that suits your personal style.
