Master Massage 6 Quart Hot Massage Stone Heater Warmer Heating Device

I really liked this heater. It holds a large number of stones — I placed 28 medium-sized stones inside with no problem. It heats up very quickly and lets you select the exact temperature you want, in either Fahrenheit or Celsius. It reaches the desired temperature and keeps it steady throughout the session, which is perfect for professional use. It’s very easy to use, safe, and works great for both professional and personal purposes. Delivery was super fast, and it arrived in perfect condition. The only downside is the lid design. Once you remove it, there’s no convenient place to set it down. It would be much better if it had a built-in system to anchor the lid upright right there. Because of this detail, I’m giving it 4 stars instead of 5. ✅ Professional use ✅ Practical ✅ Fast heating ✅ Easy temperature control ✅ Works with °F and °C Highly recommended!

Great hot stone warmer. We had been using a normal crock pot and it was challenging making sure the stones were warm enough but not too warm. This warmer heats them up quickly and does a good job of keeping the temp steady. I would love if a manufacturer for these would create a silicone lining so that the stones aren’t quite so loud hitting metal but overall this was a solid buy

I purchased this unit in April 2025. Within 6 weeks it has developed rust on rim under lid, and rust spots on sides and bottom of inner container. I cleaned everything, but rust returned within a week, and unit is worthless, even though it heats perfectly. I missed return by 2 weeks. This is not remediable, and should not happen. Do not buy this. Update: There is a strong possibility that the rust came from the basalt rocks that this device heated. I had previously used river rocks for many years in a clinical setting, but now have found out that basalt has a high iron content. I had recently added 4 new basalt rocks to the water bath, along with the many years used river rocks. Based on that, my review of the heater is changed to a 5 star, because it heated beautifully, and will forego using basalt rocks unless they are heated in a dry heater.

It doesn't heat up like the other heater I had before. But it'll work.

I love that I can set the temperature I want the stones to be. I also love that it tells me what the actual temperature of the water/stones is at any given time. I've been using this for almost a month now and haven't had any issues with this product. Works well.

I’m a massage therapist and I love this hot stone warmer it heats fast within 10 minutes

Didn't heat as quickly as I had hoped. The ambient temp on the right says it's reached capacity, but the stones took more than 90 min to get to temp. I lined mine (inside and rim) with silicone so the rocks wouldn't clang and the lid would be silent as the lid is light weight and feels like aluminum. Not a lot of room for stones unless you double layer and then bottom stones are hotter than top. Fits 6 palm sized and 2 smaller working stones comfortably. Comes with a spoon to scoop stones. Ultimately I still have my roaster so now I have 2 going during massages with stones in each. This unit does heat faster than my roaster (takes 2 hrs to heat stones in roaster) but not like I was expecting from the reviews I read. All in all it'll work, but I'd definitely get the larger size and plan extra time for clients.

Easy to use, works great. Love that I can set the temperature, and see what the actual temp is at the same time. It was quite a bit cheaper here on Amazon than the place I normally buy my massage supplies.

Llevo ya tiempo con ella, y no me ha decepcionado la verdad si la recomiendo, tardo algo en llegar por ser 2 países distintos creo, pero cuando llego no me decepciono y caliente rápido

Calienta y mantiene la temperatura muy bien, pero es importante, y eso no lo pone en la descripción del producto, que viene con un enchufe inglés y te tienes que comprar un adaptador. Yo compré uno de los chinos por 2,50€ y no pasa nada, pero el chasco me lo llevé antes cuando iba ya con el calentador lleno de agua y piedras no pude usarlo hasta que compré el adaptador.

Great Price, perfectly functional, works amazing with Jade stones, or any Hot Stone sets. It's a small heater so you can only fit aprox 4 big stones, then the rest will be working stones, and toe stones.

Heats the stones nice and easily, maintains a steady tempreture. Excellent.

Es perfecto para tener las obsidianas con la temperatura que necesito en las terapias. Gracias!!
