Sand Fire Garden




So many people have hung out with the warmth and played in the sand of my wonderful Fire Gardens have asked me how they could make one of their own.
This instructable will walk you though the basics of building your very own Zen Fire Garden.

I’ve taken the guess work out of all the fittings and sizes and put together a few kits that I use all the time in my work. You will need to find or make your own container, and build a stand or a base.

Step 1: Plumbing Parts

You will needs some basic off the shelf parts to make a fire pit:

1) Regulator/hose 30 PSI (not a BBQ regulator) and a needle valve to adjust the flame size. I use brass 3/8 45deg flair fitting for the hose ends and the attachment at the fire pit.
2) Fire ring. This is the distribution system that is below the sand for your gas. If you have the ability to weld and make rings you can make your own using a 1/2 weldable (not cast iron) coupler in the center,  5/8 thin wall tubing and drilling 3/32 holes every 1 1/2". The ring should 1/2 - 1/3 the size of your container diameter.
Stainless steel will prolong the life of the ring especially during the winter when you forget to cover your pit in the first rain.
3) Fittings. A 1/2 NPT coupler (weldable), Brass1/2 to 3/8 45 deg flare (for attaching the hose to)(not used in this build), brass 1/2 NPT nipple (to attach the the ring to the coupler welded to the container)(not used in this build), brass1/2 NPT lock nut
4) BBQ sized propane tank.

I've put together an affordable kit of the basic plumbing supplies you'll need to build your own fire pit.
I offer several sizes of rings, stainless upgrades and fully auto systems for high end remote controlled fire pits.

I now offer a new bulk head coupler that works in materials upto 1" thick. No welding required! see the last 2 photos on this page

Step 2: Container for the Fire Pit

With a little searching though your local hardware store, garden center, junkyard or restaurant supply you can find great ready made vessels to build your own custom fire garden in.

In addition to the plumbing parts you will need a container that isable to handle high temperatures and be fully sealed underneath (leaks or drain holes will also allow gas out and fire where you don't want it). The bottom 6-8" of a 55 gal drum works good. I have also used a wok, Stainless Salad bowl, or dog bowls. Stay away from painted steel, aluminum, and galvanized steel as these will release fumes or melt. The weldable coupler  can be welded though the bottom, I also sell a bolt on coupler, or a lock nut (see step 4).
I have seen people make these in cement, ceramic pots, and I have used mine with a 3' pipe added (to move the hose away from the heat) right in the beach sand.

Step 3: Adding a Hole for the Plumbing

Locate and mark the center of the wok, then center punch. Make sure you are center punching with a hard object backing up the other side. if you don't your mark will be too light and you risk just making a big dent. Now using a step drill in picture 2 drill a 7/8 hole. if you find the bit wandering off center go back and make a better center punch. Stainless steel is very hard and lots of pressure is need to get the first hole on the step drill. Step drills are a great way to make round holes in thin materials. Normal drills tend to make oblong holes in thin materials and a large hole is really not recommend with standard drill bits. A step drill can be found at your local hardware store in the drill section, or in the electrical area for making knock outs for EMT conduit. they are not cheap and a more economical  solution is a hole saw. These come in the diff sizes. Use 7/8 for the set nut ( this build) or 1 1/8 hole for the bolt in and weld in coupler.

Step 4: Adding the Plumbing

For this build I use a brass 1/2 NPT x 3/8 45 deg flare fitting with a brass1/2 NPT set nut. It fits snug in the hole and needed no additional sealant or welding.
I used gas Teflon tap on the brass, slipped though the hole and threaded the ring to it on the inside. Use a wrench to make sure it's tight. Make sure the holes are pointed down so the sand doesn't run in.

Alternates methods of plumbing the gas though the container for thicker materials:
Bolt on flange- great for thick material. Make sure to use a high temp silicon sealer to make sure there are no leaks. see attached photo
Weldable coupler- The best solution, but you must be able to weld.

Now attach the hose/regulator using the 45 deg flare fitting on the end of your hose.

Step 5: Making a Stand

I used 1/2x1/4 steel strap for both the ring and legs.
I first rolled the steel in a slip roll. This could also be done with a bending can make one with a vise by clamping two bolts 3/8" apart. Now leverage the steel between and bump (small bend, move 1/2 bend again) till you have a ring. Weld the ends together, then true it up with a hammer.

I then cut 3 16" pc and hammered the end flat on the anvil, Using the bending fork I bent the legs to match my drawing.
Now divide the ring into 3 and tack weld each leg to it. Now you can true up each leg to be square to the ring and landing the same distance from the center of the ring. Now weld solid.
I finish mine with paint.

If you can't weld get creative with plumbing parts, bolt on legs, set it into a metal bucket, cement pit are just a few ideas.

Step 6: Add the Sand

Set on top of your new stand, hook up the regulator to the propane BBQ tank and add sand. Sand should be 3-4″ above the ring. I use play ground washed sand from the hardware store.

This is a match light system and I like a plumbing torches or BBQ lighters to light mine. Light the torch, then turn on the gas with the flame above the sand. It will take several seconds for the sand to fill with gas and rise to the top.Now use the needle valve to adjust the flame. Once lit it’s time to play in the sand with simple tools (see pictures). This works best after dark when you can turn the flame down very low tell you only see a blue flame.


Do not ever touch the sand with your hands or any other part of your body! It will stick and burn you. Use caution, common sense and remember fire is hot!

Don't worry about fire traveling up the hose, but do make sure you fittings are leak proof (soapy water is a good way to test).

Keep your tank as far away as possible from your pit.

Here is a video of it at a party the next day after I built it. The noise is from a Tesla coil show next to us from my good friends at Omega recoil.

    Question 6 months ago on Introduction

    Hi we are retrofitting our new wood fire pit to work on propane we are looking to purchase a 24 inch ring with two smaller rings inside we were like the entire


    What about using a different medium for the filler? Instead of sand, maybe glass cullett... The propane shouldn't get hot enough to cause any melting, etc...

    You can find the burner, hose, adapter, and maybe even the regulator at almost any hardware store. Any place that sells parts to fix or build a gas grill should be able to help you get everything you need.

    It would also be a great way to transform some of those outdoor fire pit bowls! Re purpose them into this, which would be a great more wet wood to worry about! :) Can one get a larger ring to do that? I have not looked into it yet...nice build!! Great idea! Cheers!

    I like that. I have one that's copper - I built a real fire pit with retaining wall stones.
    I can make the old copper one for days when I don't want to make a wood fire.

    I think I'm going to make something like this and just bury it in the ground.
    I could make my own Flaming Geyser -

    These are very cool indeed! I live in an area of high fire danger and any kind of wood, charcoal etc fires are not allowed in the summer because of hot embers. This would be perfect for our backyard. Thank you for sharing!


    Reply 3 years ago

    No, you would need a much higher temperature as in a clay kiln for melting glazes. Also, you can get what is called a KILN SAND...and that takes very very high temps and is used to keep larger clay items from cracking and warping during a high temp firing. Have fun!

    spiffy to say the least!

    Could someone frame the containers outer edge with wood to make a resting spot for plates,cups, marshmallow sticks. Or, would the container get to hot for the frame.

    I know this ible is old but I'm wondering if I could gel fuel cause I'm kinda scared of gas. I know it wouldn't it would throw off any heat. Also could u use glass marble-like stuff instead? With the gel fuel it wouldn't get so hot.

    You still sell those kits, correct? Looking to order one next week.

    My project pics below, first pic of the fire pit when I got it. Second pic is of my modifications to make it propane

    i love this, is awesome for a porch or deck to set the mood right. i will definitely be making one myself in the near future hopefully. thanks a bunch for the ible!!


    I'm looking to build something a little similar. I'm trying to make a propane fuels fire extinguisher training system.
    I envisage this consiting of a stainless steel 'tray' with 'sparge pipe'. Water covers the sparge pipe and a piezo ignitor lights the propane after it bubbles through the water.
    I'm just wondering about controling the propane with a 'deadman's switch' type valve in addition to the regulator & needle valve so if I released it the gas shuts off.
    This intructable has helped me start my plan as it uses some of the same ideas.
    Very clearly put togehter too.

    very creative use of materials. Love your website.


    Thank You. I took some of your ideas and using some 1/2 conduit bent a round ring and tig welded it to make my burner. Using a standard BBQ regulator from a scrap BBQ I made a nice patio feature out of an old concrete planter.

    Next I'm moving onto making a sand feature out of a Square Fire Pit.

    Cool Work!
