LegendFlame 71-Inch Smart Fireplace
Best for: Buyers who want one fireplace that can be configured for a single-sided, corner, or three-sided view. It stands out for its installation flexibility and smart-home controls.
The listed overall dimensions are 72 inches wide, 19.5 inches high, and 10.2 inches deep. Visible dimensions are 70.9 inches wide, 15.7 inches high, and 5.5 inches deep. It includes a remote and can connect to Alexa or Google Assistant over Wi-Fi. Its heater offers 750W and 1500W settings, and the flame and fuel-bed colors can be changed.
Consider: Its wide body needs substantial space. Measure the planned opening against both the overall and visible dimensions before purchase.
OSEYM 80-Inch RGB Fireplace
Best for: Shoppers who want configurable flame colors and a crackling sound effect. The product listing names 251 RGB flame options, app and remote controls, three groups of lights, a timer, and both log and crystal media.
The heater is listed with 750W and 1500W settings. This combination of lighting, sound, and media choices makes it a better fit for buyers focused on customizing the fireplace’s appearance and ambiance.
Consider: At 80 inches, it is a large-format option. The provided product details do not specify its installation dimensions, so confirm the required opening and clearances before planning a built-in installation.
OSEYM 80-Inch Mirrored Fireplace
Best for: Buyers drawn to a mirrored 3D look alongside smart controls. The listing describes a Wi-Fi built-in fireplace with 251 RGB LED flames, app and remote control, crackling sound, and a timer.
Its stated 750W and 1500W heater settings make it comparable in listed heat modes to the other 80-inch OSEYM option. Choose this model if the mirrored design is a priority; the other OSEYM listing specifically identifies log and crystal media and three groups of lights.
Consider: The product information provided does not give overall dimensions or detailed installation requirements. Verify those measurements before committing to a wall or enclosure.
36-Inch Three-Sided Built-In Fireplace
Best for: Buyers planning a smaller built-in fireplace or seeking a shorter alternative to 71- and 80-inch models. Listed features include multi-color flames, a heater, a DIY crystal and log set, and app and remote controls.
The 36-inch width is the key comparison point for shoppers with less wall space or a more compact design plan. Its included media choices may also suit buyers who want to adjust the firebed appearance.
Consider: The provided details do not state its heater wattage, exact installation dimensions, or control features beyond app and remote operation. Check the listing for those specifics before purchase.
LALAHOO 72-Inch Wi-Fi Fireplace
Best for: Buyers who want a choice between recessed installation and wall mounting. The listing describes three-sided glass, Wi-Fi and remote controls, a 1500W heater, 12 flame colors, and five brightness levels.
The flame effect can operate with or without heat, which gives buyers a way to use the visual feature independently of the heater. Its 72-inch width places it between the 36-inch and 80-inch options in this roundup.
Consider: The product details do not provide specific installation dimensions or describe the required wall-mount hardware. Confirm the measurements and installation requirements for the setup you plan to use.
Buying Guide: How to Choose a 3-Sided Glass Fireplace
How much width and depth does the installation allow?
Start with the wall or enclosure, not the appearance of the fireplace. Compare the unit’s overall dimensions with the opening and available depth. The LegendFlame listing gives both overall and visible measurements; for the other models, check the manufacturer’s full installation specifications before building an enclosure.
Do you need a built-in, wall-mounted, or convertible design?
Installation styles are not interchangeable. The LALAHOO listing specifies recessed or wall-mounted use, while LegendFlame can be configured for one-, two-, or three-sided viewing. Confirm that the model’s stated configuration matches your project rather than assuming every three-sided unit supports corner or wall mounting.
Which controls and flame features matter most?
Choose controls based on how you expect to use the fireplace. Options in this group include remotes, smartphone apps, Wi-Fi, and voice-assistant operation. Flame customization ranges from the LALAHOO’s listed 12 colors and five brightness levels to OSEYM’s 251 RGB flames. Sound effects and alternative firebed media are separate features, so check which are included with the model you select.
Is heat a primary need or mainly an extra?
Compare the listed heater settings rather than relying on appearance or width. Several products identify 750W and 1500W modes, while the LALAHOO listing specifies a 1500W heater. Consider whether you want heat and flame effects to operate separately; the LALAHOO description explicitly says its flames can be used with or without heat.
Frequently Asked Questions
What does three-sided glass mean?
It means the fireplace is designed to show the flame through the front and two side viewing panels. The exact installation and viewing configurations depend on the model.
Can a three-sided electric fireplace be installed in a corner?
Some models support corner viewing, but not all listings confirm it. LegendFlame specifically describes one-, two-, and three-sided configurations; verify the setup instructions for other models.
Can the flame run without heat?
The LALAHOO listing says its flame effect can run with or without heat. For other products, check their product details rather than assuming they offer the same setting.
Which model is best for a smaller space?
The 36-inch built-in model is the narrowest option in this selection. Still, confirm its full dimensions and required clearances before choosing it for a particular opening.
What should I check before buying?
Verify overall dimensions, installation method, required opening, electrical and heater details, included controls, and the specific flame or sound features. These details can vary substantially between models.
