Description
A fire feature can look like an add-on or like it was always part of the design. The Outdoor Plus Del Mar 84" is firmly the latter — a long, low, rectangular GFRC concrete fire pit with the clean silhouette of high-end architectural hardscape rather than a bulky bolt-on.
Hand-poured and finished in the USA, the Del Mar pairs the cast-stone look of concrete with real weather resistance. At 84 inches it is built for a full seating group — a large sectional or two facing sofas — rather than a two-chair corner. Choose from 18 concrete finishes, five ignition systems, and either natural gas or liquid propane.
Why the 84" Del Mar
Sized for a real seating group, not a corner
The 84" measures 84" L x 28" W x 15" H, with a 68" x 12" burning area running the length of the opening. That length is what lets a full sofa-and-chairs arrangement face the flame instead of crowding one end of it. If your seating plan is smaller, the 48", 60" or 72" Del Mar will suit you better and cost less.
190,000 BTU across the whole length
The burner is matched to the body, so the flame runs the length of the opening rather than sitting as a small pool in a large table. Suggested fire glass fill is 86 lbs if you upgrade from the included lava rock.
GFRC concrete, not ordinary cast concrete
Glass Fiber Reinforced Concrete is meaningfully stronger and more weather-resistant than standard cast concrete, so the refined look holds up to real outdoor exposure instead of cracking or degrading after a season or two. Because each unit is hand-poured, subtle variation in color and texture is normal and expected — that is the material, not a flaw.
Choosing Your Options
Natural gas or liquid propane
Natural gas runs off a plumbed line and never needs refilling, which is the better answer if you already have a gas stub or are willing to have one run. Liquid propane runs off a tank, which means no plumbing but a tank to swap and somewhere to hide it. Pick the one that matches your property — the burner is configured for your choice at the factory and cannot be swapped later.
The five ignition systems, in plain English
- Match Lit — the simplest and least expensive. You turn a key valve and light it yourself. No power needed.
- Match Lit with Flame Sense — the same, plus a sensor that shuts the gas off if the flame blows out.
- Flame Sense with Spark — adds a push-button spark so you are not holding a lighter over the burner.
- Low Voltage Electronic (CSA certified) — on and off from a remote or a wall switch. Needs a transformer and a power source nearby.
- Plug and Play (CSA certified) — the same convenience, wired to plug into a standard outlet. The easiest of the electronic options to install.
If an inspector or local code is involved, the CSA-certified options are the ones with documentation on file.

Delivery & Installation
Delivery included. Built to order, ships in 3–4 weeks.
Your fire pit is built for your order — your finish, your ignition, your fuel type — so it isn't pulled off a shelf. Production runs about 3 to 4 weeks, then it goes out on a freight truck. Figure four to six weeks from your order to your patio.
Delivery is included in the price you see. No freight bill afterward, no surprise at checkout. Delivery is to the continental US, to your driveway or a designated spot on the property, with a liftgate where the size allows.
When it's built, the freight carrier calls you to set a delivery window. Someone needs to be home to meet the truck and sign for it. Look the crate over before you sign — freight damage is rare, but it can only be put right if it's noted on the paperwork at the time.
Professional installation. As a gas fire feature, the Del Mar should follow all clearances and local codes for your selected fuel type, and professional installation is recommended. If you don't have a preferred installer, contact us and we can point you toward qualified professional installation for your setup.
Built for you, so please double-check your choices. Because each unit is made to your specification, we can't return or exchange it once it goes into production. Take a minute over the finish, the ignition and whether you're on natural gas or propane. Not sure? Call 1-800-914-0074 or email sales@optimaloutdooroasis.com and we'll walk through it with you — we'd much rather answer questions first.
