Cannonball sets: ceramic fire balls in 2, 4, or 6 inches for a linear burner
The Grand Canyon Gas Logs Cannonball sets are solid ceramic fiber balls, hand molded and dyed all the way through, that sit in a bed of lava granules over a burner instead of logs. They come in 2, 4, or 6 inch sizes and in black, gray, or white. Stack one size in neat rows, or mix sizes and colors for a looser look. Use them indoors or out, in a front-view or see-through fireplace or a linear fire pit.
Order it for natural gas or propane. The price shown is for a single set. On the page, you pick the ball size and color and a burner width from 18 to 60 inches. The page adds the number of sets that width needs. You also choose an indoor glass burner or an outdoor stainless steel burner, along with a control ranging from a safety pilot you light by hand to an electronic ignition system. Lava granules and fire glass in seven colors are optional. Prefer wood over spheres on a linear burner? See the Linear Western Driftwood log set. The Cannonball set ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.

FAQ
Can I mix the three Cannonball sizes for a custom look?
Yes, that is the idea behind the series. The spheres come in three sizes of 2, 4, and 6 inches, and you can keep to a single size for a clean minimalist arrangement or combine sizes for a random, one-of-a-kind stack. Mixing the scales adds depth to the fire and lets you tailor the look to your opening instead of settling for a fixed pattern.
Will the color burn off the spheres over time?
No. Each sphere is hand-molded ceramic fiber that is dyed through and through, so the Black, Gray, or White color runs the full depth of the material rather than sitting on the surface as paint. With no finish coat to flake or scorch away above the flames, the set keeps its look through regular fires indoors or out.
Do these work with drop-in outdoor pan burners?
Yes. The sets are compatible with Glass H and T burners, Ring, H, and T burners, and all drop-in outdoor pan burners, so they can dress an existing pan rather than requiring a dedicated burner. That compatibility list covers the most common burner formats, which makes the spheres straightforward to spec alongside a new burner or retrofit over one you already own.
What is the story behind the Cannonball design?
The design is modeled on civil-war-era cannonballs — authentic casted pieces with a period character that reads surprisingly modern once flames are moving around them. Each sphere is hand-molded from ceramic fiber, and like every Grand Canyon product the sets are 100 percent American-made in Phoenix, Arizona, where the brand casts and finishes its fire media.
What do the lava granules and crushed glass add?
They complete the brand’s signature presentation: the Cannonballs are designed to be nestled in a bed of lava granules surrounded by crushed reflective glass. The granules give the spheres a natural seat over the burner, while the reflective glass bounces flame light around the matte ceramic shapes — a combination Grand Canyon recommends for elevating indoor and outdoor fireplaces alike.
Can the same set style an outdoor linear fire pit?
Yes. The sets are rated for indoor and outdoor use in vented applications, covering front-view and see-through fireplaces as well as linear fire pits. Warranty follows the setting — lifetime for indoor installations, five years outdoors. That range makes these some of the most flexible contemporary gas logs in the lineup, moving from an interior firebox to a patio feature without a second purchase.
How many fire spheres do I need to fill a fireplace?
Each set is sized as a complete display: CB2-12 brings twelve 2-inch spheres, CB4-8 brings eight 4-inch spheres, and CB6-4 brings four 6-inch spheres, built around a configuration three rows deep and two rows high. If you want a fuller field of spheres or a mixed-scale look, combine sets — the sizes are made to mix and match.

What Our Customers Say

A sauna turns your garden into a spa oasis. We debated it for a while, but after renovating our house, we pulled the trigger and bought a sauna from Norse Steam and Maya. She was always super responsive and helpful throughout the process. Don't kid yourself, getting a really nice sauna is not that easy. Sizing and heating need to be figured out, as does the building, but we have always had a helpful partner on our side. She never upsold us on anything we didn't need, and we got some nice freebies when the sauna was delivered. And now we can really enjoy every moment in our garden.
KF
I'm really happy with my sauna purchase. Maya gave above and beyond excellent customer service. She wasn't pushy and gave impressive followup after the delivery to make sure everything was just right.
DE
I enjoy my FD2 Sauna with Red Light, Infrared and radiant heat. Use it 5x a week and my post workout soreness is minimal and sleep great. Maya at Norse Steam was excellent to work with.
B
We purchased the 3-person sauna for our outdoor garden. We chose the cube sauna for the aesthetic and could not be happier.
I assembled by myself except for the 2 large panels (requires a few people). Instructions were good - took me two partial Saturdays to complete and a few hours to unpack and organize in advance of assembly. Had my elec. add a NEMA enclosure on the back for the controller and power for lights and a 2nd panel for the wireless control.
Customer service was excellent

Awesome Sauna and Awesome Company and Experience purchasing it from Maya!
After much research I chose the Finnmark FD-2 and it has met and exceeded all my expectations! Easy to assemble and it functions great - just as advertised. I highly recommend it for home use!
EA
Recently purchased the Finnmark one person after much research. Extremely happy with it and the ordering process. Maya was very responsive and helpful during the process and keeping us updated while we waited for shipment. There were several places I could have ordered this, but i chose Norse Steam based on the communication and customer service which was fantastic. The shipment was also excellent. The setup was pretty seamless for two people - but the best part is the sauna experience 10/10

Maya is amazing - super helpful and responsive. Looked at many stores, these guys have the best prices and service. Highly recommend
GR
Norse Steam, and specifically Maya, were extremely helpful as I was making the decision for our Sauna. I was able to get all of the necessary details to make a decision as construction was happening in my backyard to make space for it.
We absolutely love the CL7G. It is extremely comfortable for 6 people (can fit more less comfortably). The Thermory Spruce and Aspen in the interior smells great. The lighting is lovely. We paired the CL7G with the Harvia Spirit 10.5kw.

Had great experience shopping at Norse Steam for the new heater. They had very good deal, with rocks. Customer service was good, and responded very fast with my questions. Received the heater, and it looks good, and the quality seem to be great. Will install soon, and am very excited to start experiencing sauna the way it ment to be

Smoking Hot Tub!
I got the Norse Steam SaunaLife wood-fired hot tub, the S4N model, and its been seriously great. It heats up quicker than I expected, usually around an hour and a half, and once its hot, it stays that way for a good long while. The wood-fired system is simple to use, and honestly kind of fun.
The tub itself feels solid and well put together. The thermo-spruce exterior looks beautiful in person, and the fiberglass interior is smooth, deep, and easy to clean. Its the kind of setup that just works without a bunch of fuss, which I really appreciate.
Also, the team at Norse Steam was genuinely great to work with. Super helpful, quick to respond, and made the process really easy from start to finish. It felt like they actually cared that I was happy with it. The tub has totally become a go-to way to unwind, and I wouldnt change a thing.

Great Sauna & Purchase Experience
Great experience purchasing Finnmark FD-2 from Norse Steam. Good communication and easy to assemble. Temperature increases quickly (30 minutes or less to 140) and maintains well. So far this has been a great purchase.
M
Great sauna and great customer service
We purchased the Finnmark SD-1 sauna. Maya was extremely helpful with the purchase. We had an issue with the sauna not reaching the maximum temperature, and Maya connected us with the appropriate technician that explained how to correct the issue. The sauna now heats to the maximum temperature (170 degrees) in less than an hour, and it is a great unit. We are very happy with it, and we would definitely purchase from NorseSteam if we needed any other items.

Sauna Review
I recently purchased a sauna from Norse Steam, and I couldn't be more impressed with the entire experience. From start to finish, their customer service was exceptional, and Maya deserves special recognition for her outstanding support!
Maya was incredibly knowledgeable and patient, answering all my questions about the sauna features, installation process, and maintenance. She went above and beyond to ensure I selected the perfect model for my home. Even after the purchase, Maya followed up to make sure everything was running smoothly and that I was satisfied with my sauna.
The sauna itself is top-notch beautifully designed, durable, and easy to use. It's clear that Norse Steam takes pride in the quality of their products and their commitment to customer satisfaction.
If you're considering a sauna, I wholeheartedly recommend Norse Steam. With their excellent customer service and high-quality products, you're in great hands. Thank you, Maya, and the entire Norse Steam team for a fantastic experience!
