If you're planning a frameless built-in fireplace installation, Remii electric fireplaces are worth examining closely. Powered by Amantii, a Canadian hearth manufacturer with close to 40 years of experience in the industry, Remii focuses exclusively on zero-clearance built-in units with a clean-face installation profile. Every Remii fireplace is approved for indoor and outdoor covered applications, including bathrooms, and all three series ship with Canyon Brown and Ocean Blue decorative fire glass, a remote control, and a black steel surround for covering rough opening gaps after installation.
The lineup is focused: three series differentiated by firebox depth and flame viewing height. That makes the selection process more direct than it is with brands that offer dozens of overlapping configurations. The right Remii model is mostly determined by your wall depth and how large a flame display you want.
All three series output 4,800 BTUs and are rated for up to 500 sq. ft. of heating coverage indoors. Each runs on 120V, 15A power at full heat (1,500W), and each is hardwire-ready in addition to being plug-in capable. What changes between series is the depth, the viewing window size, and the framing requirements.
The Extra Slim is the thinnest Remii model and the only one designed to fit in standard 2x4 stud wall framing. With a 4-inch overall depth, it requires no custom framing or built-out wall sections. It's available in four sizes: 35" ($1,599), 45" ($1,799), 55" ($2,099), and 65" ($2,299), making it the only Remii series with a sub-40-inch option. The Extra Slim is also the only Wi-Fi enabled model in the Remii lineup, with smartphone control via app in addition to the included remote. The overall unit height is 19 7/8", requiring a 20 3/8" rough opening height. In The Fireplace USA's catalog, it holds a Best Seller designation.

The DEEP series uses an 11 7/8-inch firebox depth, which requires 2x6 or thicker wall framing, or a dedicated built-out chase, for a clean installation. The rough wall opening height is 25 inches. In return for the additional depth, you get a larger firebox volume and a flame that reads as more substantial in bigger rooms. Available in 45" ($2,499), 55" ($2,899), and 65" ($3,399) widths, the DEEP supports optional designer media kits that let you replace the included fire glass with logs, stones, pebbles, black glass, or vermiculite. Heat vents from the front of the unit, so installing a TV directly above the fireplace is safe.
Worth Considering: Remii DEEP Frameless Built-in Electric Fireplace
The Extra Tall shares similar framing requirements to the DEEP (12 5/8 inches deep), but adds a taller viewing window. The flame viewing area is approximately 17 3/4 inches high, compared to a standard-height electric fireplace. The overall unit height is 29 1/2 inches, requiring a 30-inch rough opening height versus the DEEP's 25-inch requirement. Available in 45" ($2,499), 55" ($3,299), and 65" ($3,699) widths. The 45" Extra Tall is priced the same as the 45" DEEP, which makes it a straightforward upgrade if you're already planning for deeper framing and want more vertical flame presence.
A Popular Choice: Remii Extra Tall Frameless Built-in Electric Fireplace
The Extra Slim is the default starting point for any project with standard 2x4 stud walls. Renovations rarely justify reframing a wall for a deeper firebox, and the Extra Slim's 4-inch profile allows a clean, modern installation without touching the wall structure. It's also the most practical choice for bathroom installations, where wall depth is almost always constrained. The Wi-Fi app control makes it the best fit among the three for smart-home setups.
The DEEP suits new construction or gut renovations where you're framing the wall from scratch and can specify 2x6 depth. It also works well in open-plan living rooms with generous wall space, where the deeper firebox adds presence and the 45" to 65" width options provide strong visual coverage across a feature wall.
The Extra Tall fits best where vertical impact is the priority. Spaces with 10-foot ceilings or higher benefit from the taller flame window, and feature walls that need a strong vertical focal point are a natural fit. For buyers who want the fireplace to serve as the primary visual anchor of a room rather than a background element, the Extra Tall justifies the taller rough opening requirement.
All three series carry approval for covered outdoor use, a rating not common across the broader electric fireplace market. A covered patio, lanai, or outdoor living room qualifies, provided the unit is not exposed to direct rain or weather. The bathroom approval is similarly specific to covered indoor spaces.
Most built-in electric fireplaces are rated for indoor use only. Remii's consistent outdoor covered and bathroom approval across all three series is a genuine differentiator for projects that need this flexibility. The clean-face installation approach is also distinct: you can finish tile, stone, or drywall directly to the glass face for a zero-frame appearance, or use the included steel surround for a more defined bordered look.
Compared to higher-end brands in the category, Remii's flame presentation is straightforward: yellow, orange, and red flame color options with adjustable intensity. The lineup does not include the multi-color LED palettes or advanced flame technology found in some other brands, and the media kit options, while functional, are more limited than some competitors. For buyers who want a clean, honest fire presentation without added complexity, this is a reasonable fit. For those who prioritize flame realism and customization depth, Amantii's own lineup warrants a closer look.
Pricing sits in the accessible-to-mid range for the category. The Extra Slim starts at $1,599, which is competitive for a frameless built-in with outdoor approval. The Extra Tall at 65" runs $3,699, which is mid-range for large built-in electric fireplaces. All models carry a 2-year manufacturer warranty.
The Fireplace USA carries all three Remii series across the full size range. Browse the complete Remii collection to compare specs, dimensions, and pricing side by side. All models include Canyon Brown and Ocean Blue fire glass, a remote control, a black steel surround, and a 2-year warranty. Optional designer media kits are available separately.
Both series have similar installation depth requirements (11 7/8" for the DEEP, 12 5/8" for the Extra Tall) and identical heat output. The primary difference is the flame window height: the Extra Tall's viewing area is approximately 17 3/4 inches high, requiring a 30-inch rough wall opening height, compared to the DEEP's 25-inch requirement. Pricing at the 45" width is identical. At the 55" and 65" widths, the Extra Tall runs $400 more than the DEEP counterpart.
Yes. All three Remii series are approved for indoor and outdoor covered applications. The units must not be exposed to direct rain or moisture. A covered patio, outdoor living room, or screened enclosure qualifies. All three are also approved for bathroom installations.
The Extra Slim operates on a standard 120V, 15A circuit. At full heat (1,500W), it draws about 12.5 amps, so a dedicated 15A circuit is recommended to avoid tripping a shared breaker. At flame-only mode (25W), the draw is negligible. The unit is plug-in capable and also hardwire-ready if you prefer a cleaner installation without an exposed outlet.
All three series ship with Canyon Brown Fire Glass and Ocean Blue Fire Glass as the standard decorative media. Optional designer media kits, sold separately, include decorative logs, stones, pebbles, black glass, and vermiculite. These kits allow you to change the firebox look without modifying any core components.
Remii is a separate product line powered by Amantii. They share the same parent company and manufacturing background, but Remii is marketed as its own brand with its own model names and design focus. Amantii's own line includes additional configurations and technologies not found in the Remii lineup. The Fireplace USA carries both brands.
