Touchstone Sideline Infinity 3-Sided Fireplace Series
The Touchstone Sideline Infinity Pro is a deep, nearly frameless electric fireplace that can show flame through the front, left side, right side, or all three sides. Removable side panels let the same firebox support a clean front-facing installation, a corner, or a panoramic bay configuration.
Its deeper viewing area holds driftwood and crystal media, while multi-zone color lighting and a built-in crackle speaker give the display more dimension than a shallow linear fireplace. Smart controls and supplemental heat round out the series.
