A corner fireplace is a multi-sided fireplace designed to create flame visibility from more than one direction. In modern architecture, corner fireplaces are used to anchor open floor plans, define transitions between spaces, and create a cleaner visual connection between rooms.
What Makes a Corner Fireplace Different?
Most fireplaces are specified flat against a wall, limiting flame visibility to one direction and anchoring the focal point to a single area of a room. Flare’s frameless linear gas corner fireplaces change that by wrapping continuous flame across two or more open glass faces, creating multi-sided visual connection to the fire.
The result is a fireplace that bridges two adjacent walls, defines transitions between zones, and transforms what was once dead corner space into the design centerpiece of a room. Whether the project is a modern residence, a luxury hotel lobby, or a high-end commercial environment, a corner fireplace creates a sightline dynamic that a flat fireplace simply cannot match.
Flare offers four corner configurations, each designed for a specific architectural condition:
- Left Corner Fireplace — glass faces front and right; installs in the left corner of the room
- Right Corner Fireplace — glass faces front and left; installs in the right corner of the room
- Double Corner Fireplace (Bay) — glass wraps a full corner bay with flame visible on three sides simultaneously
- Room Definer Fireplace (Peninsula) — freestanding peninsula projecting into the room with flame visible on three or four sides
All four configurations share Flare’s frameless design language: no visible metal frame, no surround clutter, just fire and glass. Each is available in multiple widths, three glass heights, and a choice of media including black diamonds, glowing embers, and driftwood logs.
The Four Corner Configurations
Flare builds four corner configurations. They share the same frameless design language and differ in how many faces the flame wraps and where the unit sits in the room.
Left and Right Corner
The Left Corner installs in the left corner of the room with glass facing forward and to the right; the Right Corner is its mirror, facing forward and to the left. Both open the flame across two adjoining faces, and because Flare builds them to identical specifications they can be paired in a symmetric room to frame a central seating zone. On the Celebrity IOU project with Howie Mandel, a Left Corner anchored a luxury entertaining space, and the Cosentino collaboration used an 80-inch Left Corner clad in large-format stone to create a monolithic, frame-free fireplace wall.
Double Corner (Bay)
The Double Corner wraps glass across three faces — front, left, and right — so the flame reads from every angle and becomes the structural anchor of a large room. The Frank Wright Double Corner shows this at full scale: an 80-inch unit with 24-inch glass visible at once from the kitchen, dining area, and main seating zone.
Room Definer (Peninsula)
The Room Definer is freestanding, projecting into the room with glass on three or four sides. Rather than fitting into a corner, it uses fire as a boundary — separating living from dining, or sleeping from sitting — without building a wall or blocking light. It is Flare’s tool for defining zones in a fully open plan.
Why Architects Choose Corner Fireplaces
Architects and interior designers specify corner fireplaces when a single flat wall of flame cannot do justice to how a space is actually lived in. By wrapping continuous flame across two or more open glass faces, a Flare frameless linear corner fireplace becomes a focal point that several zones can share at once — which is why it appears repeatedly in open-plan, multi-use, and luxury projects. These are the reasons design teams reach for a corner configuration over a flat, front-facing fireplace.
Open Floor Plans
In open floor plans the challenge is giving a large, undivided volume a center of gravity without erecting walls. Positioned where the kitchen, dining, and living zones meet, a corner fireplace’s two-sided flame anchors the entire floor while keeping sightlines open. Flare’s frameless glass keeps the design visually light, so the fire — not a bulky surround — reads as the architectural feature that organizes the room.
Multi-Room Visibility
A corner configuration makes the flame visible from more than one direction at the same time. Where a flat fireplace serves a single seating area, a Flare Left, Right, or Double Corner fireplace can be enjoyed from the living room and the kitchen, or from a hallway and an adjoining lounge. For architects, that multi-room visibility is the core reason to choose a corner over a front-facing unit — one fireplace earns its place in several rooms at once.
Room Transitions
Corner and peninsula fireplaces are powerful tools for managing how one space hands off to the next. Placed at the junction between two areas, the fireplace marks the transition without closing it — a fire you move around rather than a wall you move through. Flare’s Room Definer (peninsula) configuration is purpose-built for this: it defines a boundary between living and dining, or sleeping and sitting, while preserving flow and natural light.
Modern Luxury Homes
In high-end residential work the fireplace is often the signature moment of a room. Architects choose Flare corner fireplaces for luxury homes because the frameless, edge-to-edge glass and continuous flame deliver the minimalist, gallery-like aesthetic these projects demand — no visible frame, trim, or hardware to interrupt the surrounding stone, plaster, or millwork. The result reads as architecture rather than appliance, which is why Flare corner units appear in projects with brands such as Cosentino and builds featured on Celebrity IOU.
Hospitality Spaces
Hotels, restaurants, lobbies, and lounges use fire to create atmosphere in spaces that are seen from many angles and occupied for long stretches. Corner and Double Corner fireplaces suit these environments because they project warmth and ambiance across a wide field of view, and Flare’s Cool Touch Wall and heat-management options support more flexible fireplace wall planning when installed according to Flare’s manuals, clearance requirements, and project-specific specifications. For projects that span an indoor-outdoor threshold, Flare’s see-through indoor-outdoor models extend the same design language to exterior-facing walls.
Primary Bedroom Suites
In primary bedroom suites a corner fireplace lets one unit serve both the sleeping area and an adjacent sitting room, spa bath, or balcony. The wrapped flame creates intimacy from the bed while remaining visible from the lounge or en-suite, turning the suite into a single connected retreat. Lower-profile glass heights and Flare’s heat-release options keep corner fireplaces comfortable in the more enclosed volumes typical of bedrooms.
Specifying a Flare Corner Fireplace
Beyond width, glass height, and media choice, the specification detail that matters most on a corner unit is heat management — because the fireplace is flanked by walls or built-ins on two sides rather than one. Flare’s Cool Touch Wall technology helps manage heat around the fireplace wall and can support more flexible finish options when installed according to Flare’s installation manual, heat release requirements, and project-specific specifications, and the Active Heat Flex System gives designers control over how heat exits the unit.

Frequently Asked Questions: Corner Fireplaces
Can a corner fireplace be used as a room divider?
The Room Definer (Peninsula) configuration is specifically designed for room division. It creates a visual and thermal boundary between zones without building a wall — ideal for open floor plans in luxury residential and hospitality environments. The Left, Right, and Double Corner configurations install into corners against two walls and are not designed for freestanding room division.
What glass height should I choose for a corner fireplace?
Flare corner fireplaces come in three glass heights, and the right choice depends on your ceiling height and what sits above the fireplace — artwork, a flat screen, or a structural ceiling element. A lower glass height leaves more wall plane above the flame, while a taller glass creates a more immersive flame presence that can become a full-height architectural feature. As a rule, match the glass height to the visual weight you want the fire to carry in the room.
What is a frameless corner fireplace?
A frameless corner fireplace is a gas fireplace built into the corner of a room with no visible metal frame or trim around the glass, so the flame appears to meet the surrounding wall material directly. Flare’s frameless corner fireplaces wrap a single continuous linear flame across two adjoining glass faces, giving an uninterrupted, edge-to-edge view of the fire from two directions — the defining look of a modern architectural corner installation.
Can a corner fireplace be used outdoors?
No. Flare corner fireplaces are designed for indoor installation and are not rated for outdoor use. For a project that needs fireplace on an exterior wall or across an indoor-outdoor threshold, a different Flare configuration — such as a see-through model or Flare Fireplaces outdoor — is the right choice. Confirm the correct model and rating with Flare at 1-866-639-1590 before specifying any exterior or indoor-outdoor application.
