Outdoor Fireplace Kits Built to Your Dimensions

An outdoor fireplace kit is a pre-engineered firebox and surround that arrives ready to set and finish, instead of a mason building one course by course in your yard over three weekends.

Ours start at $2,283.90 for a 72-inch single-sided fireplace and run to $5,347.50 for a 90-inch model with a built-in TV wall. Ready-to-finish fire pit kits start at $1,310.14. A site-built masonry fireplace with a crew typically starts past $10,000 and takes weeks.

Sizes are the overall width. Firebox dimensions, crate weight and pallet count come with your quote — we won't guess at them here, because the number that matters is the one for the model you actually order.

Two-sided or single-sided?

A two-sided see-through fireplace is the one worth thinking about. It divides a patio from a lawn, or a dining area from a lounge area, and both sides get the fire. At 72 inches it costs the same as the single-sided version, so the decision is about the space rather than the budget.

The single-sided models sit against a wall or a privacy fence and throw everything forward.

Ready-to-Finish Fire Pit Kits

48″ rectangle Ready to finish $1,310.14
60″ round Ready to finish $1,718.27
72″ round Ready to finish $2,172.29

48″ x 32″ rectangle Arrives finished in aluminum cladding $2,619.00
48″ round Arrives finished in aluminum cladding $2,790.00

Add a granite top for $948.75 (36″) or $1,247.75 (48″), and a 25.5″ burner pan for the 48″ round for $290.

Worth knowing what the alternative costs: the best-known ready-to-finish gas fire pit kits on the market sell at $4,712 and $5,673. These do the same job.

If you'd rather buy a fire pit that arrives complete and needs no finishing at all, that's a different aisle — see our finished fire pits and fire tables, from $335.

Kit vs. Built On Site

Fireplace kit Site-built masonry
Cost $2,283 – $5,348 $10,000+ with a crew
Timeline Set and finish over a weekend Weeks, weather permitting
Who builds it You, or your landscaper A mason
Firebox engineering Done for you Depends entirely on the mason
Finish Your stone, tile, stucco or brick Your stone, tile, stucco or brick
Looks custom when done Yes — the finish is what shows Yes

The finish is what a guest sees. Nobody standing on your patio can tell whether the firebox behind the stone was engineered in a shop or stacked on site — but your wallet and your calendar can.

What You Still Need

  • Finish material. Stone veneer, tile, stucco or brick, bought locally or through us. This is the part that moves the budget.
  • A gas line, if you're running gas rather than wood. Licensed pro, no exceptions.
  • A level base. Concrete pad, pavers or a footing, depending on the model and your ground.
  • Your local rules. Some towns require a permit for a permanent outdoor fireplace, and wildfire-risk areas restrict wood burning. Check before you order, not after.

Delivery and Freight

These ship by freight truck on pallets. Freight is quoted to your address and billed at cost — we don't mark it up and we don't bury it in the price. You get the crate weight, the pallet count and a real delivered number with your quote, before you commit to anything.

Built to order, so lead time depends on the model. We'll give you a firm number with the quote rather than a guess here.

Paying by bank transfer saves you 3% on the product.

Outdoor Fireplace Kit Questions

Can I DIY an outdoor fireplace?

With a kit, yes — that's the entire point of one. The firebox arrives engineered and ready to set, so you or your landscaper are handling placement, leveling and the finish rather than the fire engineering. Building one from scratch without a kit is genuinely mason's work, and a badly built firebox is a fire risk, not just an ugly one.

What is the best fireplace for outside use?

For most properties, a pre-engineered kit finished in stone or stucco. It gives you the permanent built-in look without the cost or the schedule of site-built masonry. Choose gas if you want it easy to light and easy to pass local code, and wood if the crackle is the point. If you're dividing two spaces, a see-through model earns its keep twice over.

What is the typical cost to build an outdoor fireplace?

A kit runs $2,283 to $5,348 for the structure, plus finish material and labor — call it $4,000 to $9,000 finished, depending on what you clad it in. Site-built masonry with a crew generally starts past $10,000 and climbs from there.

Do it yourself outdoor fireplace kits — what's included?

The engineered firebox and surround structure, with the openings already in the right places. Finish material, gas line and base are separate. We'll tell you exactly what's in the crate for your model before you order.

Can I get an outdoor fireplace kit with a pizza oven?

Yes. A 54″ wood or charcoal-fired pizza oven cabinet is $2,715.67 and can be built into a run alongside a fireplace or an outdoor kitchen. Ask for it on your quote.

Do you have larger outdoor fireplace kits?

The 116″ straight box is the widest standard model at $3,444.25. Past that we build to your dimensions — send measurements.

What's the cheapest outdoor fireplace kit you sell?

The 72″ single-sided at $2,283.90. If you want fire for less, a ready-to-finish fire pit kit starts at $1,310.14, or a finished portable fire pit starts at $335.

Can it go on a deck?

A fireplace, generally no — they are heavy and permanent. That is a slab or footing job. If a deck is what you have, look at our lightweight aluminum-framed builds for decks instead.

Building More Than a Fireplace?

Fireplaces, fire pits, pizza ovens and outdoor kitchens are all built on the same frame system and can be quoted as one run. If a kitchen is part of the plan, start with custom outdoor kitchens and we'll price the whole thing together.

Works the same at a house you live in — the fire doesn't know it's not a rental.
