What is a three-sided (peninsula or bay) fireplace?
A three-sided fireplace has glass on three faces — the front and both ends — so the fire projects into the room like a peninsula or bay window of flame. It is viewable from nearly anywhere in an open plan and reads as sculpture as much as heat. Almost all are sealed direct-vent gas.
Three-sided vs. see-through
It's easy to mix these up. A see-through fireplace opens on two opposite faces — front and back — and works as a divider between two rooms. A three-sided unit keeps one solid back and puts glass on the front plus both ends, so the flame pushes out into a single room. A peninsula version projects from the end of a wall or island; a bay version wraps the corner. Either way, you can see the fire from almost every seat in the space.
Where it shines
Three-sided units are made for open floor plans. Set one at the end of a peninsula between the kitchen and living area, on the corner of a great room, or projecting into a wide-open mountain-modern space where you want the fire visible from the sofa, the dining table, and the kitchen at once. With that much glass, the flame becomes the room's centerpiece the moment it's lit — and a clean, well-lit interior even when it's off.
Design and install realities
More glass means more hot surface, so a barrier screen matters where kids and pets are around — the outer glass on a running gas unit gets hot. You'll also style three faces instead of one, and the framing depth and venting run take planning, which is why these belong in a new build or full remodel. Direct-vent routing and the gas line are licensed work: we size the unit to the room, honor every clearance, permit it with your county, and pressure-test the line.
