Real Fyre Mixed Select Fyre Spheres: mixed size ceramic spheres for a vented fireplace
The Real Fyre Mixed Select Fyre Spheres is a vented set of ceramic fire spheres that takes the place of logs. The mix of sphere sizes suits a modern room. Pick Epic Black or Graystone on the page. It is a vented set, so it needs a real fireplace with a working chimney and burns with the damper open. You get the tallest and most natural flames, and most of the heat goes up the chimney. It comes in 18, 24, or 30 inch sets. Measure your firebox at the front, at the back, and front to back, and if you land between two sizes, take the smaller set.
The spheres are ceramic, made to sit in the flame, and the burner wraps its flame around them. The price is for the spheres only. On the page you pick natural gas or propane and add the P45 pan burner. You also pick how it lights: by hand with a match on natural gas, with a knob and a pilot light that stays lit, or with a remote that sets the flame height. A Fyreback, a steel panel that stands behind the fire, is optional. Prefer spheres all one size? See the Real Fyre Vented Fyre Spheres. The Real Fyre Mixed Select Fyre Spheres ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.

FAQ
What does Mixed Select mean on this sphere set?
Curated variety: instead of uniform spheres, each FSM box holds a pre-determined combination of different sphere sizes, arranged as modern groupings on the P45 burner. The staggered scale reads more organic and sculptural than a single-size row, which is exactly the effect the Mixed Select was designed to give.
Which finishes does the FSM come in?
Two: Epic Black and Graystone, both produced with Real Fyre’s updated finish durability. Epic Black plays as bold, high-contrast sculpture against the flame, while Graystone sits quieter and more neutral in the firebox. There is no marble option in the mixed run; that finish belongs to the uniform FS sets.
How do I match a set size to my burner?
The FSM comes in 18, 24, and 30-inch sets, each sized to the corresponding width of the P45 burner system it sits on. Choose the set matching the burner already in your fireplace, or if you are starting from scratch, the P45 width your firebox measurements call for.
Are sphere sets a real alternative to logs?
Real Fyre positions them exactly that way: a contemporary alternative to traditional gas fireplace logs, with the FSM’s dynamic flame pattern enveloping the mixed spheres instead of licking through a log stack. The gas burner underneath works the same; only the sculpture in the fire changes.
Is there a right way to set out the mixed spheres?
Yes, and Real Fyre documents it: the FSM ships as pre-determined combinations of 4-packs with a recommended stack sheet showing how the sizes group on the P45 pan. Following it keeps the flame pattern wrapping the spheres as designed; freelance arrangements tend to look cluttered and can crowd the burner.
Does a contemporary set like this still need the damper open?
It does. The FSM is a vented product on the P45 burner, so it operates like any vented gas fire: damper open, flue live, and the emphasis on flame display with radiant warmth as the bonus. If you need closed-damper heating, look to Real Fyre’s vent-free contemporary burners instead.
Can I mix the two finishes together?
The mixing in Mixed Select refers to sphere sizes, not colors: each FSM box is all Epic Black or all Graystone. Nothing stops a homeowner from combining boxes, but the recommended stacks are composed per finish, so a two-tone arrangement is a custom styling decision rather than a documented Real Fyre configuration.

What Our Customers Say
D
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.
RS
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!
