A natural gas fire table is an outdoor concrete fire table permanently plumbed to a home’s natural gas supply line — no propane tank to store, swap, or run out of. For homeowners with an existing outdoor gas stub-out, or for anyone building a new outdoor space where a gas line is being rough-in during construction, natural gas is the more convenient long-term fuel choice. Castin Crete Designs builds every fire table in the lineup as a natural-gas-ready build, with fuel type confirmed at the time of order.
The case for natural gas is simple: you light the fire and it runs until you turn it off. No monitoring tank levels before a gathering. No mid-evening swap. No hauling a 20-pound cylinder to the exchange rack at a hardware store. For homeowners who entertain frequently or who want a fire table that functions like any other permanent outdoor feature — reliably, without logistics — natural gas is the right configuration.
When Natural Gas Makes Sense for a CastinCrete Fire Table
Natural gas is not always the default. It is the right choice when at least one of the following is true for your property:
Your outdoor space already has a gas stub-out. Many Wisconsin homes built or renovated in the last 15 years have a capped gas line at the patio, installed during construction for exactly this purpose. If that stub-out exists, natural gas is the straightforward path — a licensed plumber connects the fire table’s supply line to the existing stub-out, and you are done.
You are doing a hardscape project and gas rough-in is part of the scope. If a contractor is already breaking ground — installing pavers, building a retaining wall, pouring a new patio slab — adding a gas stub-out at that stage costs a fraction of what it costs to trench and run line after the hardscape is finished. This is the moment to make the decision.
You plan to use the fire table very frequently. Natural gas has a lower per-BTU fuel cost than propane, and the convenience premium compounds over time. If the fire table is running three or four evenings per week through a Wisconsin summer, the ongoing fuel savings add up and the installation cost amortizes quickly.
Natural Gas Configuration in CastinCrete Builds
Every CastinCrete fire table — the Quadra, Timberline, Summit, Harmony, Monolith, and Highline — is available in a natural gas configuration. The GFRC concrete form is identical to the propane version. The difference is internal: natural gas builds include a fixed connection fitting sized for natural gas supply pressure and a burner calibrated for natural gas BTU output.
Natural gas burns at a lower BTU output per cubic foot than propane, so natural gas burners are sized accordingly to produce comparable flame height and heat output. The visible result — the flame character, the coverage across the burner opening, the warmth at seating distance — is the same as a propane build of equivalent burner diameter.
Installation Requirements
A natural gas fire table requires a dedicated gas stub-out at the installation location. Connection must be made by a licensed plumber or gas fitter — this is required by code in Wisconsin and in every Waukesha County municipality. If you are ordering a natural gas build and do not yet have a stub-out, plan for that work to be completed before the table arrives. CastinCrete can advise on typical lead times and coordinate delivery around your installation schedule.
The table itself ships with the connection fitting in place. Once the gas line is stubbed out and the table is positioned, a licensed professional makes the final connection in under an hour. No ongoing maintenance beyond the connection itself.
Natural Gas Fire Tables and the Highline
Natural gas is the more common fuel choice for the Highline linear fire table specifically. The Highline is designed for permanent, fixed placement — lakefront decks, pool surrounds, extended covered patios — where the table does not move and where running a dedicated gas line to a fixed location is practical. A 20-pound propane tank is adequate for a compact rectangular fire table; at linear scale, the supply logistics tip toward natural gas for most buyers.
If you are planning a Highline build for a lakefront property on Pewaukee Lake, Okauchee Lake, Nagawicka Lake, or anywhere along Wisconsin’s Lake Country chain, natural gas is worth the conversation before you finalize fuel type.
What a Natural Gas Fire Table from CastinCrete Costs
CastinCrete natural gas fire tables are priced from approximately $2,995 depending on the model, size, and configuration. The natural gas configuration does not carry a premium over propane — the cost difference between fuel types is in the installation, not in the fire table itself. Visit the individual product pages for current pricing, or call the studio to discuss your project and fuel configuration.

Frequently Asked Questions
Can I convert a natural gas fire table to propane later?
It depends on the burner configuration. It is best to specify fuel type at the time of order. Converting after the fact requires a burner swap and regulator change, and should be performed by a licensed gas professional. If you are uncertain which fuel type you want, discuss it with us before ordering — it is not a decision to reverse easily or inexpensively.
Do I need a permit to install a natural gas fire table in Wisconsin?
Yes. Any connection to a natural gas supply line requires a permit and must be performed by a licensed plumber or gas fitter in Wisconsin. Requirements vary by municipality. Most Waukesha County cities require a permit for new gas connections regardless of scope. CastinCrete can advise on typical requirements in the communities we serve.
Does a natural gas fire table require a dedicated gas line?
Yes. Natural gas fire tables connect to the home’s gas supply via a dedicated stub-out at the installation location. This stub-out must be installed by a licensed professional before the table arrives. CastinCrete ships the table with the connection fitting in place; final connection is made by your gas contractor on site.
How does natural gas flame compare to propane on a CastinCrete fire table?
The visible flame character is comparable. Natural gas burns cooler per cubic foot than propane, so the burner is sized to compensate and produce equivalent flame height and heat output at seating distance. Most buyers cannot distinguish a natural gas flame from a propane flame at normal fire table use.
Can I see natural gas fire tables at the showroom?
Call (262) 501-9966 to confirm current display configuration at our Hartland, WI showroom at N77 W31144 Hartman Court Ste. E, Hartland, WI 53029. We can discuss fuel type configuration during your visit.
Does CastinCrete ship natural gas fire tables outside of Wisconsin?
Yes. CastinCrete ships nationwide via freight carrier with liftgate delivery. Natural gas builds ship ready to connect — installation requires a licensed gas professional at the destination regardless of location. Freight is quoted at the time of order based on destination and table dimensions.
