No renovation. New fire.

“The s16-in integrates into your existing masonry hearth, restoring its full function ... without major renovation work.”

I

The width stays

“In a masonry hearth, the width of the opening is part of the experience. The s16-in preserves it, offering a fire view that is nearly as generous as the original.”

II

A face that disappears

“Its clean lines fade into the background... With no visible handle, the door is opened using a removable key. Convection is fully integrated. No visible grilles interrupt the design.”

III

Three frames

Finishing frames in StûvGrey for every size: Thin-edge (“frameless effect”), Picture-type 2″, Picture-type 4″ — the retrofit dressed exactly to your masonry.

Quick answers

The three things everyone asks.

Do I need a chimney?

You have one — that’s the point. The 16-in slides into your existing masonry fireplace and vents through a 6″ or 7″ stainless liner per the maker’s install instructions. We sweep, line and install it WETT-certified.

Will it fit my fireplace?

Three widths (22-7/8″ to 30-3/4″) cover most masonry openings, and the three StûvGrey frames trim the reveal — thin-edge for a frameless look, 2″ or 4″ picture frames to cover more brick. Send us three measurements; we fit-check before any order.

What’s the upkeep?

Ash out, glass wiped via the removable key, one annual sweep — our trade, same crew that installs 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.
