Urbana · U70 Tall Edition

The three-sided one.

Urbana’s bay firebox in its tall edition — 2,637 square inches of glass, wrapped corner to corner.

I

Three sides of glass

Front and both sides — one wrap of fire, the corners sealed glass to glass. In Urbana’s words: “No Steel Pillars.”

II

Nothing between you

“Double Glass Safety” — “a second layer of ultra clear glass,” no screen required, and “no gaps” top to bottom.

III

An ember bed that performs

Driftwood or split logs, river rock, glass or shale — under optional LED lighting whose “color is adjustable and can be controlled via a mobile app.”

Quick answers

The three things everyone asks.

Will it fit my wall?

It frames at 70¾″ wide with a 43⅝″ opening height and 21″ of depth, and the tall edition wants 95⅛″ floor-to-ceiling. Send us a photo of your wall and we’ll confirm the fit before you spend a dollar.

Is it really open on three sides?

Yes — the front and both sides are glass, corners sealed glass to glass with “no steel pillars,” in Urbana’s words. “Double Glass Safety” keeps the outer surface guarded, no screen required.

What’s the upkeep?

No wood to haul, no ash to sweep. Like any gas fireplace it wants an annual service — that’s our trade, and the crew that installs it does it.

What it costs

Priced to your home — not from a chart.

Every wall is different — framing, venting, gas line — so your price is real, not a guess.
