Why the Symmetry Xtra Slim Wins
The Symmetry Xtra Slim brings the clean linear aesthetic of the Symmetry series into spaces where a full-depth recessed fireplace isn't an option. The slim profile fits within a 2x4 wall, but the full-frame viewing area and adjustable multi-color flames deliver a premium result that doesn't look like a compromise. WiFi controls come standard, and the 11 tray lighting effects add an ambient layer that transforms the room even when the heat is off.

Which Symmetry Series Is Right for You?
The Symmetry lineup includes four distinct series. Here's how they compare so you can choose with confidence.
| Series | Best For | Key Difference | Starting Price |
|---|---|---|---|
| Symmetry Lumina | Budget-conscious buyers who want clean-face linear style with WiFi | Same clean-face design as Bespoke at a lower price — 2-year warranty, media included out of box | $1,899 |
| ⭐ Symmetry Xtra Slim (This Model) | Spaces where wall depth is limited — condos, apartments, renovations | Ultra-slim profile fits tight spaces — indoor only, 42"–60" sizes, lowest starting price in the lineup | $1,679 |
| Symmetry Bespoke | Most buyers — the best balance of features, size range, and warranty | 5-year warranty, indoor & outdoor rated, 7 sizes from 34"–100", Fire & Ice flames | $2,299 |
| Symmetry XT Bespoke | Large rooms, great rooms, commercial spaces, statement walls | Extra-tall flame display, built-in Bluetooth speakers, up to 10,240 BTU — the most immersive Symmetry | $3,999 |
Not sure which series? The Xtra Slim is the right choice when wall depth is a real constraint — condos, apartments, or renovations where you can't open up the wall. If wall depth isn't a limitation, the Symmetry Bespoke gives you more size options, a longer warranty, and indoor/outdoor rating for a comparable entry price.
Which Size Is Right for You?
| Size | Best For | Price |
|---|---|---|
| 42" | Bedrooms, home offices, smaller living rooms, and accent walls | $1,679 |
| 50" ⭐ Most Popular | Standard living rooms and family rooms — the best balance of presence and value | $1,909 |
| 60" | Larger living rooms, open-plan spaces, and media feature walls | $2,019 |
Sizing tip: For a balanced look, your fireplace width should be roughly two-thirds the width of your wall or furniture grouping. When in doubt, size up — a slightly larger fireplace always looks more intentional than one that feels too small for the space.
