Sauna Rocks/Sauna Stones, 35 lb Box of Lava Rock for Steam Sauna, Sauna Stone

I use them in my russian sauna.

I washed these rocks, put them in my heater, and the first few uses they were fine. The 4th time a terribly toxic smell started coming off them. I took them out and inspected them. Some had split already. When I put them in the heater they were all your typical grey color. Now some had sides that were completely white, some red, some showed bright deposits of...I have no idea what I'm seeing. I'd look else where for sauna rocks.

These lava rocks are perfect for the sauna. There’s a nice variety of sizes and you have enough for a variety of applications if you’d like. It took a while to get these delivered, but it was worth the wait. At first, I wished that there were more of the medium and larger sizes… but there more I think about it, the happier I am of the ratio of sizes they gave… the smaller size has more surface area which I’d imagine make them more effective regarding temperature and minerals and any beneficial off-gassing/steam. My only recommendation is that you reasonably clean each rock before using them in a sauna situation… otherwise, you may encounter stronger smells that could be detracting from your experience. While these are great for the sauna, you could also use these as accents in your garden or around your office. Lava rocks do have good anti-emf properties as well and are grounding in nature, so take advantage of this if you can’t afford lots of shungite, etc.

Be careful! Rocks will pop and shatter on initial use. Some rocks are pretty large for small home saunas.

I love rocks in all shapes and forms and have many different types throughout my yard, so when I saw these I ordered right away. The rocks were delivered in approximately 6 weeks by USPS. There are 32 rocks ranging in size and thickness and weight. None were them were very large. I have a four inch smooth Mexican beach pebble in last picture as reference to size. I'd say their description was pretty spot on concerning the varying size. Collectively they feel heavy (35#) but are easily managed. The majority were of the same color, but a couple had whitish hues. When I had read that they are sauna rocks, I knew these rocks would be very happy living here where it feels like a sauna most of the days outside...very hot, humid environment. None of them was big enough to use as a border, so I scattered them amongst to hang out...I like them very much.

The first time I used these rocks there were about 10 very loud explosions as moisture trapped inside of the rocks turned to steam and exploded sounding like gunshots. After one such explosion a quarter size piece of rock fell out of the bottom of the sauna heater. It was a bit scary but I think eventually the rocks will stop exploding.

Our sauna is small and these rocks popped and cracked so violently, a chunk flew out and burned my leg. The next day I downloaded a rock identifying app that stated these are not volcanite, but are in fact slate. Very, very dangerous to use in a sauna! Ended up throwing them in the river nearby. Waste of money. This seller should be banned! False advertising! And Amazon wouldn't even refund the purchase as I used them on a day just over the 30 day return period. Shameful.

We recently purchased a sauna for my wife hoping that it would make her feel better. We needed some good volcanic rock to put into the heater so that we could have it to pour water on to create steam. This rock is a very attractive style rock and is dark grey in color and each piece looks as if it were hand sculpted. There are no bad rocks and they are all attractive. Once set in place on the heater and the heater was brought up to temperature we poured our first amount of water on them. One must remember that the water used in saunas should only be distilled as otherwise the minerals in regular water will discolor the rocks. They heated up quite nicely and looked great. They performed as expected and I would give them a 10 out of 10 if given the chance.
