Corner electric fireplaces

This is the practical answer for most people, and the reason is install rather than flame. Touchstone lists it as a wall-mount three-sided unit with zero-clearance installation and a finished mantel — you hang it, you plug it in, you are done. The two Westinghouse units below can also be surface-hung, but they arrive as bare fireplaces with no mantel and no surround; the Infinity Pro sizes are recessed only, which means framing a corner opening before the unit arrives.

Specs are 750 W and 1,500 W heat settings with a 400 square foot supplemental rating, tempered glass on three faces, LED flames with adjustable color and intensity, and WiFi with Alexa and Google alongside remote and manual control. It comes in black (80034) and white (80033).

The honest con is the one that applies to this whole page: three-sided glass is a geometry upgrade, not a thermal one. The heater is the same 1,500 W as a flat unit at a fraction of the price, and on a flat wall two of the three panes face nothing.

What it does not do: Three-sided glass needs a corner or a peninsula wall to make sense. Against a flat wall you pay for two panes nobody ever sees.

Three-sided units skew large, which is a problem because corners are usually where a room runs out of space rather than where it has plenty. At 40 inches this is the one that suits a genuine corner in a normally sized living room.

It is part of Touchstone's Infinity Pro three-sided range, which runs 40, 50, 60, 72 and 84 inches on the same recessed format.

Two cons. It is recessed, not wall-mounted, so there is no hang-it-and-plug-it option — you are committing to a framed corner opening. And Touchstone publishes less numeric detail on its collection pages than the mass-market retailer listings do, so confirm the rough opening with the brand before cutting a corner apart.

What it does not do: Three-sided glass only earns its money on a corner or a peninsula. Recessed into a flat wall, two of its three panes face into framing nobody will ever see.

Fifty inches is the width at which a linear fireplace stops looking tentative, and on a peninsula or a room divider a three-sided 50 reads as architecture rather than as an appliance stuck in a wall. What makes this one the practical choice at that width is that it does not force the install: Westinghouse publishes it for wall-mounting or in-wall flush recessing, in front, two-sided or three-sided configurations.

Published as 750 W and 1,500 W settings with a stated 5,110 BTU per hour, 50 in wide by 17 in high on the front, a 50 3/8 by 17 1/2 by 8 1/2 in recessed opening, 144 flame and ember color combinations across five brightness levels and five flame speeds, interchangeable faux log and birch-and-crystal ember beds, a 62 to 82 °F thermostat, 63.5 lb, and remote, app, Alexa and Google control.

Three cons. Westinghouse documents the settings but not the flame mechanism, so the listing cannot tell you how the flame is actually made. Because it hangs flat as happily as it recesses, it is easy to end up with a three-sided unit on a flat wall where two panes face nothing — the shape only pays on a corner or a peninsula. And if you do recess it, the corner opening is still two walls meeting, with framing on both planes and a header wherever you cross a load-bearing stud — see how to mount and recess.

What it does not do: Westinghouse does not document the flame mechanism itself, only the color and speed settings, so read our taxonomy rather than the listing if mechanism matters to you. It is a three-sided unit that can also be hung flat, which means two of the three panes face nothing on a flat wall — the shape only pays on a corner or a peninsula. No mantel and no surround.

On a peninsula — a wall that stops partway across a room, with living space on both sides — three-sided glass stops being a nice touch and becomes the entire point. People genuinely view it from three directions, so all three panes do work, and this is the width at which that reads as deliberate.

Published as 750 W and 1,500 W settings with a stated 5,110 BTU per hour, 60 in wide by 17 in high by 7.88 in deep, a 60 3/8 by 17 1/2 by 8 1/2 in recessed opening, the same 144 flame and ember color combinations, five brightness levels and five flame speeds as the 50, interchangeable log and ember sets, a 62 to 82 °F thermostat, overheat protection, and remote, app, Alexa and Google control with a hardwire option.

Three cons, and the middle one is a documentation problem rather than a product one. Sixty inches of three-sided glass needs a peninsula deep enough to carry it and a room big enough that it does not dominate. Westinghouse's 60 in page repeats the 50 in model's front-facing dimension and weight, so we quote neither here — plan from the 60 3/8 in cutout, which is size-specific, and confirm the weight with the seller before you plan a hang. And thermally this buys nothing: the same 1,500 W and the same stated 5,110 BTU per hour as the 50 in, for ten more inches of glass.

What it does not do: Westinghouse does not document the flame mechanism, and its 60 in page repeats the 50 in model's front-facing dimension and weight, so we quote neither for this size — measure against the 60 3/8 in cutout, which is size-specific, and confirm the weight with the seller before you plan a hang. Same 1,500 W and 5,110 BTU as the 50 in: sixty inches buys glass, not heat. No mantel and no surround.
