How to Build a Faux Fireplace Under $600: Before and After

Step-by-step tutorial for building an affordable DIY faux fireplace using faux stone, shiplap, a stacked-log firebox door, and a repurposed antique mantel.

Once upon a time I wanted something more for our living room — a focal point that was worth the wait, worth the work, and would finally make the space feel complete. I didn’t expect it to actually heat the room (it’s faux, after all), but I did dream of a fireplace that felt real and cost far less than the typical $5,000 builder upgrade.

After months of hunting Craigslist and pinning every DIY faux fireplace I could find, my husband and I settled on a plan to build a statement-making fireplace on a tight budget. We finished the whole project for under $600, and the result finally made our living room feel cozy and intentional.

Before

When we moved in we had a few sad hand-me-downs and a tiny bookshelf acting as an entertainment center. That wall needed weight and character. We considered a built-in or full renovation, but decided a faux fireplace would give us the impact we wanted without the huge price tag.

Project Overview

This project was completed in several phases. Parts 1–3 cover the hearth, mantel, firebox framing, plank wall above the mantel, wiring the TV behind the fireplace, and whitewashing or painting the faux stone. This article focuses on Part 4: creating the stacked-log firebox door and final touches.

DIY Faux Fireplace — Stacked-Log Firebox Door

Supplies

• Pre-cut wood slices or small logs (or logs you can cut yourself)
• 3/4″ plywood for the firebox door
• Circular saw, miter saw, or band saw (if cutting your own log slices)
• Matte black or chalkboard paint for the door backing
• Paint brush
• Strong wood glue (we used Gorilla Glue)
• Piano hinge to hang the door

Steps

1. Cut the plywood to the desired dimensions of your firebox door with a circular saw or similar tool.
2. Paint the plywood with matte black paint (or chalkboard paint) and allow it to dry completely.
3. Cut log ends to uniform thickness. We used 2″ slices for a convincing stacked depth; a band saw works well. Our log story: my in-laws found a beech tree that had been cut by a beaver — free, eco-friendly craft material!
4. Lay the painted plywood flat and arrange the log slices until you like the composition. Treat it like a puzzle and move pieces until they sit right. This step can take under an hour if you stick with it.
5. Glue the log pieces down with a strong adhesive. Be sure to position everything first before gluing so you can adjust placement as needed.
6. Once the glue has fully dried (we waited 24 hours to be safe), attach the door to the firebox opening using a piano hinge.

Finishing Touches

While the glued pieces dried I painted the faux stone (Air Stone) above the mantel. Although I had whitewashed it earlier in the project, I ultimately painted the entire surface with Sherwin-Williams pure white leftover paint to create a cleaner, more cohesive look that wouldn’t compete with the stacked-log door and the mantel’s architecture.

Electronics and TV Placement

We originally hoped to hide electronics inside the firebox, but the stacked-log door became quite heavy and made internal access awkward. Instead we kept devices on the mantel and use the outlet inside the firebox only occasionally. For now, a leafy artificial vine helps disguise the speakers, Blu-ray player, and game console.

If you want a TV-free mantel, plan your room layout first — sometimes the best visual choices aren’t practical for everyday life.

Alternate Firebox Option

If the stacked-log look isn’t for you, you can build a faux firebox with faux brick paneling instead. We explored that alternative in a later update (Part 5) and it offers a different, equally attractive aesthetic.

Project Wrap-Up

I’m thrilled to have this major item checked off our to-do list. Our living room is coming together one project at a time; next on the list is a new coffee table and a full room reveal once everything is styled and in place. This faux fireplace added personality and charm without breaking the bank, and it gave us a focal point that finally feels intentional.
