FAQ
Why does the Sonoma weigh 455 pounds?
Because it is a genuinely monumental piece — roughly 48 inches across and 36 inches of sculptural cast concrete. Even so, GFRC keeps the Sonoma far lighter than the poured-concrete equivalent, which would be immovable. This is the fire pit you position once, deliberately, as the anchor of the whole space.
What are the specs at a glance?
SKU OPT-SONMA38, footprint about 48 by 48 inches and 36 inches of height, 455 pounds, in 18 hand-finished GFRC colors from Ash and Bronze to Rustic White and Vanilla. Built to order for Liquid Propane or Natural Gas, handmade in the USA.
What ignition options exist?
Five: Match Lit, Match Lit with Flame Sense (LC certified), Flame Sense with Spark, Low Voltage Electronic (CSA certified), and Plug and Play (CSA certified). Given that the Sonoma tends to be a set-piece installation, many owners spec the electronic systems and light it from a switch.
How much space should it get from the house?
Plan the Sonoma placement around its spec-sheet clearances plus the standard ten-foot cushion from structures. Gas means no embers drifting anywhere, which is why a piece this size can sit surprisingly close to living areas — but at 455 pounds, get the location right the first time.
Is shutdown complicated on a big unit?
Not remotely — the Sonoma goes out the moment you close the valve, same as any gas feature. No coals in a pit this size to babysit, no ash. The concrete mass holds pleasant warmth for a while after, which guests tend to appreciate.
Can you roast marshmallows over it?
Yes — clean-burning gas makes the Sonoma fully marshmallow-approved. Its generous rim actually helps: skewers rest at a comfortable angle and several people reach the flame at once. Keep sugar drips off the media and the finish, and dessert is a nightly feature.
Can it live under a covered patio?
A 36-inch-tall body plus flame puts heat close to any roof, so the honest answer is: only if the Sonoma spec clearances genuinely fit your overhead structure with real ventilation. Most installs give it open sky — which suits a centerpiece this size anyway. Compare formats in our gas fire pit range.
