How Much Lava Rock Do I Need?
Most fire pits and fireplaces work well with 2 to 4 inches of glass depth. Preferences vary; some clients are content with 2 inches, while others prefer 4 inches. Generally, we use a 3-inch glass depth as our standard. Make sure all measurements are in inches.

Got it in good condition cannot figure out why this one was so much more
than my last one
Love the color and style, Manny was of the greatest help in making our decision!! He set us up with all the piping all the way, thanks so much
Order a wood fireplace insert so far great company to buy from.
We bought a woodstove last winter. The entire purchase process went very well. The unit was packed well and arrived when it was scheduled. We are VERY HAPPY with Royal Fire Pits and would recommend to anyone looking for a new woodstove or any other fireplace accessories. Even our dogs love our woodstove...THANKS ROYAL FIRE PITS!!!
We searched for over a month to find this insert, and it met all our expectations. We purchased the additional pedestal and cast iron surround and it makes a handsome statement.Royal Fire Pits provided excellent service from ordering to delivery.
Our Vermont Castings Montpelier 2 is a fantastic replacement for our 30 year old VC insert. Well done!
The warming shelves somewhere work great and look great as well.
Well, I am hoping it will work as advertised, but after several weeks the stove itself has never arrived as advertised so I am a bit skeptical. Can you help?
Most beautiful stove you can buy. Everything I purchased was packed really well and arrived in perfect condition. Shipping was very quick to arrive. Can’t wait to start using the stove.
We are happy with Empire ventless gas stove we purchased. It is cast iron and has a nice solid look. We are using it for a little extra heat in our lower level family room and for backup heat if the power goes out as it operates without electricity. The stove was packed very well and arrived quickly with no damage. We are happy with Royal Fire Pits and their performance
I have yet to install my stove, the weather hasn't been nice enough!
Everything came as expected in a timely manner.
I am on this site to purchase another one. I bought this five years ago and it was part of the sale of my apartment, so now I have to have one for my new place. I did the research to find this five years ago and looking forward to another one. This is more expensive than ones available elsewhere, but it is superior and worth the extra few hundred.
