A recessed electric fireplace is built to sit inside a wall cavity, flush with the surface or close to it. Getting the right unit starts with one measurement: the available framing depth in your wall. Match the depth correctly and the installation finishes cleanly. Choose a model that requires more depth than your wall provides and the unit will either not seat properly or protrude past the wall face. This guide covers how to evaluate framing depth by wall type, how to choose width, and which models from our current inventory are worth reviewing across three installation tiers.
Installation involves framing an opening between studs, sliding the firebox into the wall cavity, connecting power, and finishing with a trim surround. The result is a fireplace that reads as part of the wall rather than an object placed in front of it.
The available depth in the wall cavity is what limits your choices. Most homes built with standard 2x4 framing have a stud cavity approximately 3.5" wide (the actual dimension of a 2x4), with usable depth after drywall falling between 3.5" and 4.5". Homes with 2x6 exterior framing, common in cold-climate builds for added insulation, have around 5.5" to 6" of usable depth.
Three installation tiers follow from this:
Before reviewing models, measure your available wall depth. In new construction, this means deciding whether you're framing 2x4 or 2x6 before purchasing. If you're retrofitting an existing wall, open the cavity and measure from the drywall face to the back wall or any obstruction.
Once you have the cavity depth, filter to models with a required framing depth at or below that number. Manufacturers publish this as "required framing depth" or "recess depth" in the spec sheet. The advertised product description often leads with width, not depth. Read the spec sheet before ordering.
2x4 Compatible: framing depth up to 4"
The Modern Flames Spectrum Slimline requires 3 7/8" of framing depth, which fits a standard 2x4 stud wall completely flush with no build-out required. Available in 50", 60", 74", and 100" widths starting at $1,599. The Hybrid-FX flame technology uses RGB LEDs to produce visible flame depth at close range. Output: 5,000 BTU, rated up to 450 sq ft. UL Listed, 2-year warranty.
Our Top Pick for 2x4 Walls: Modern Flames Spectrum Slimline
The SimpliFire Allusion Platinum offers two framing options: 6" standard or 4" for 2x4 walls. The 4" mode is 2x4 compatible, though it may reduce the visible viewing area slightly for some size variants. Available in 50", 60", and 72" widths starting at $1,879. CSA Certified.
2x6 / Standard Recess: framing depth 5" to 6"
The Modern Flames Challenger Series requires 5.5" of framing depth, placing it in 2x6 territory or requiring a minor build-out from a 2x4 wall. Available in 50" and 60" widths starting at $949. Features 10 adjustable flame colors, 5,000 BTU / 400 sq ft heat coverage, and a 2-year warranty. UL Listed.
Deep Recessed / Custom: framing depth 8" to 10"
The Litedeer Homes Latitude has an 8" overall depth and requires a framing pocket to match. Available in 45", 55", 65", and 75" widths starting at $2,299. Includes GT-Xview HD LED flame technology, five flame color options, Tuya smart app control, and a 1" slim trim frame. Output: 5,118 BTU / 400 sq ft. ETL/cETL Certified, 2-year warranty.
A Smart Pick: Litedeer Homes Latitude
The Modern Flames Orion Traditional requires 10" of framing depth and is designed specifically for installation into traditional fireplace openings, whether new construction with custom framing or existing masonry cavities. Available in 26", 30", 36", 42", and 54" widths from $2,149. HELIOVISION flame technology uses recorded digital flame footage rather than mechanical LED effects. The 36" and larger sizes output 8,300 BTU. CSA Certified, 5-year warranty.
Best for Traditional Openings: Modern Flames Orion Traditional
Framing depth determines which models are eligible. Width determines how the installation reads in context.
For a TV wall, the fireplace width should be close to the TV width or wider. A 50" TV paired with a 36" fireplace below it looks undersized. A 60" fireplace under a 55" TV reads as intentional.
For a feature wall without a TV, a fireplace that spans 50 to 67 percent of the wall width typically looks proportionate. On a 120"-wide wall, a 60" to 74" unit works well. Going narrower makes the installation look like an afterthought.
For a bedroom or smaller room, 50" is a common starting point for linear models. If a narrower unit is needed, the Orion Traditional starts at 26" wide with a taller viewing area that reads better in tight horizontal spaces than a short linear would.
One sizing detail to verify before ordering: the stated size (e.g., "60-inch") typically refers to the firebox or viewing area width, not the full installed width including trim. The overall product width is usually 2" to 6" wider. Check spec sheet dimensions before marking your rough opening.
Flame technology. Entry-level recessed units typically use a single flat back-panel LED display. Higher-end approaches like the Modern Flames Hybrid-FX and HELIOVISION systems create more apparent depth in the flame image through different optical methods. These hold up better at close range and from oblique angles. If the fireplace will be viewed from multiple positions in an open-plan space, flame depth is worth comparing side by side.
Electrical requirements. All models reviewed here operate on 120V and include a standard plug. The Orion Traditional in larger sizes requires a dedicated 20-amp circuit for hardwired installation. Confirm the electrical situation in your framing bay before finalizing the model, particularly in a retrofit where existing wiring may be limited.
Heat output. Most linear recessed units are rated at around 5,000 BTU, designed as supplemental heat for spaces up to 400 to 450 sq ft. The Orion Traditional 36" and larger outputs 8,300 BTU. These units are not intended as primary heat sources in cold climates.
Smart controls. The Litedeer Latitude integrates with the Tuya app. The Orion Traditional V2 supports Wi-Fi control through the Modern Flames app, including over-the-air flame updates. The Spectrum Slimline and Challenger Series are remote-controlled. Confirm app platform compatibility before ordering if smart control is a priority.
Warranty length. The Orion Traditional carries a 5-year warranty. The Spectrum Slimline, Challenger Series, and Litedeer Latitude carry 2-year warranties. For a built-in unit that requires wall work to install and remove, this difference has practical weight.
Ordering by width without verifying framing depth. Product listings typically lead with size (e.g., "60-inch built-in electric fireplace") and may not prominently display the required framing depth. The overall product depth and the required framing depth are not the same number. Always locate the full spec sheet and review framing depth before purchasing.
Assuming the nominal cavity depth is the actual one. A 2x4 stud is nominally 3.5" wide, but actual available depth in the cavity varies with drywall thickness, insulation, vapor barrier, or air gap materials. Measure the actual cavity rather than relying on nominal dimensions.
Underestimating the electrical work. Recessed installation often requires running new wiring inside the wall. If the unit needs a dedicated circuit, that cost should be in the project budget before the model is selected.
Positioning the fireplace too high for the room. A general guideline: the center of the viewing area should sit at approximately seated eye level, around 42" to 48" from the floor. TV-over-fireplace layouts push the fireplace higher to fit the screen, which works visually but changes the ambiance at seated viewing angles compared to a hearth-height installation.
The terms are used interchangeably in most retail listings. In practice, a recessed fireplace installs into a wall cavity so it sits flush or near-flush with the surface. "Built-in" is a broader term that includes both recessed units and surface-mounted fireplaces with finished surrounds. Most products listed as built-in support recessed installation; the spec sheet installation options section will confirm.
It is possible but not the standard recommendation. Exterior walls often contain insulation and vapor barriers that reduce the usable cavity depth. In cold climates, the exterior face of the firebox is exposed to larger temperature swings that may affect performance and could affect warranty coverage. Interior walls are the preferred installation surface for recessed units.
No. Electric fireplaces produce no combustion and no exhaust. They require the clearances specified in the installation manual, but no external venting is needed. This is a core advantage over gas inserts, which require a flue or direct-vent pathway to the exterior.
Both fit 2x4 walls. The Spectrum Slimline installs at 3 7/8" framing depth with no reduction in viewing area. The Allusion Platinum's 2x4-compatible mode uses 4" framing and may reduce the visible glass area slightly for some size variants. The Spectrum Slimline starts at $1,599; the Allusion Platinum starts at $1,879. For a true flush fit without any viewing-area trade-off, the Spectrum Slimline has the edge. The Allusion Platinum is worth considering if you need the 72" size, which is not available in the Slimline lineup.
After accounting for drywall on both sides, the usable depth in a standard 2x4 stud cavity is typically around 3.5" to 4". The tightest-fit model in our current inventory is the Modern Flames Spectrum Slimline, which requires 3 7/8" of framing depth. Any model requiring more than 4" will either protrude past the wall face or require a framing modification.
