A Fire That Looks Strikingly Real

The Remii Extra Slim delivers a vivid, multi-colored flame effect you can customize between warm Yellow, glowing Orange, and rich Red with a single button press. Whether you're entertaining guests or unwinding after a long day, the full-frame viewing area fills your wall with a convincing, flickering fire that sets the mood instantly. Paired with Canyon Brown and Ocean Blue fire glass, the visual effect is layered, dynamic, and genuinely impressive.

Real Warmth for Real Rooms

With 5,000 BTUs of heating power, the Remii Extra Slim efficiently warms rooms up to 500 square feet — making it a smart zone-heating solution that lets you turn down the central heat and warm only the space you're actually using. The thermostat-compatible design means you can set a target temperature and let the fireplace do the work, maintaining a consistently comfortable room without constant adjustments. It's comfort on your terms, exactly when and where you need it.

No Venting. No Gas. No Limits.

Because the Remii Extra Slim runs on standard 120V electricity, there's no gas line to run, no chimney to install, and no venting required — just a wall opening and a power source. It can be plugged in for a straightforward setup or hardwired for a fully integrated finish, and it's rated for both indoor and outdoor use so you're not limited to a single room or even a single structure. The freedom to place a beautiful, functional fireplace almost anywhere in your home — or outside it — is a game changer.

Only 4" Deep. Endlessly Impressive.

The defining feature of this fireplace is its extraordinary 4" depth — a measurement that sounds almost too good to be true until you see it installed. That ultra-slim profile means it fits into wall cavities and tight architectural situations that would rule out any other built-in fireplace on the market, all while delivering a full-frame, frameless viewing area that looks like a high-end custom installation. If you've ever been told a built-in fireplace won't work in your space, the Remii Extra Slim was built specifically to prove that wrong.
