The Steamcore™ Pro-Series 31.5 kW Steam Generator Model KWS 31.5 CELG by Saunacore is an industrial-grade steam solution designed for high-demand commercial environments, including large fitness centers, gyms, condos, hotels, and luxury residential steam showers. Featuring a surgical stainless steel boiler tank and industrial large-diameter low-density incoloy heating elements, this steam generator offers exceptional durability and reliable performance. The unit is equipped with advanced features like automatic rinse and flush operations, a steam room-temperature sensor, and a state-of-the-art electronic operations circuit board. With its compact design and energy-efficient operation, the Steamcore Pro-Series ensures powerful steam production while conserving water and maintaining quiet operation.
- Surgical-grade durability – A surgical stainless steel boiler tank paired with low-density incoloy heating elements resists corrosion, scaling, and thermal stress, delivering stable output, longer service life, and fewer interruptions in demanding, high-humidity commercial environments.
- Auto-rinse with aromatherapy – Factory SPA II steamheads include an aroma oil reservoir and automatic rinse/flush, refreshing the tank after sessions. Cleaner internals mean purer steam quality, reduced maintenance time, and consistently satisfying guest experiences.
- Precision temperature control – A dedicated room temperature sensor and advanced electronic control board manage heat and humidity tightly, preventing overshoot and drop-offs so every session feels predictable, comfortable, and on-spec from warm-up through cooldown.
- Efficient, continuous output – Compact engineering uses minimal water while producing robust, uninterrupted steam. Lower consumption helps control utilities and supports sustainability goals without sacrificing density, recovery, or comfort during extended or back-to-back sessions.
- Whisper-quiet operation – Acoustic-conscious design keeps generator noise low, preserving a serene ambiance suited to premium facilities. Quiet cycles allow conversation and relaxation to continue undisturbed while the system fills, heats, and maintains temperature.
- SSI controller convenience – The chrome SSI controller matches SPA II finishes and provides timer, temperature, and pause functions. Staff can fine-tune sessions quickly, standardize routines, and respond instantly to guest comfort requests.
- Layered safety & warranty – An ASME pressure valve with dual auto/manual flush valves adds protection and streamlined servicing. Coverage includes a limited 5-year warranty, with an optional Limited Lifetime Warranty available through a maintenance program.

Wanted to share that The Sauna Place and associate Caleb Robertson provided extremely knowable service and a great experience with their available products. I've just ordered a Harvia sauna heater with digital wall control and am looking forward to receiving for my home sauna build project.
Great company.
Ordered a Harvia Sauna Heater, shipped quickly and arrived on time. Unfortunately the unit got dented/dinged up during shipping. Caleb and the team were responsive and kind, and got us out a new unit right away. Shipped back the damaged unit, and now we are good to go!
The Harvia KIP is solid, and this company's customer service earned them a well-deserved 5 stars. Wish more companies like them were still around.
We love our sauna we purchased from The Sauna Place! We got Dundalk 5x7 and a cold plunge. It took some time to arrive but it was easy to assemble and it works and looks great! Caleb helped me with choosing the right heater for it. Dundalk saunas smell amazing! Ours is red cedar. It has two levels of benches and high ceiling. The sauna warms up to 188 F in 30 min. We have HUUM heater (the egg shaped). We got a stainless steel lined cold plunge and it works great.
Highly recommended. I purchased the sauna wood oil. Easy to apply - completely transformed my sauna.
I own Sharp Edge CrossFit in Evanston, IL., and we have a Sisu sauna for our members to enjoy. One of the coils in our sauna's heater broke. After a quick Internet search I found that the Sauna Place had the replacement parts I needed. I called them and spoke to the NICEST person on the phone. He assured me not only are the parts readily available and able to be shipped quickly, but that replacing the parts in the heater is not a difficult task. My stress pertaining to my gym members not being able to use the sauna they pay for was pretty quickly alleviated after talking to whomever I spoke with on the phone this morning. For that, I am so appreciative! Excellent customer service! And I highly recommend!
The Sauna oil Sold here is 97% paraffin which is not approved for inhalation and is a petroleum distillate. It begins breaking down at 200f and creating harmful gasses. Do not put petroleum products in you wellness sauna. This product is listed at 100% natural (bout as natural as gasoline) and its ingredients are not listed on the website. I had to call and request at MSDS sheet and then lookup the CAS codes to discover if this was harmful to my family. This is the cheap option not the good one
Update: after several more weeks of bad shipping and not being notified that the shipper could not get ahold of me I finally picked up my heater. They sent the wrong one. To their credit they made it right as fast as they could despite my rather irate disposition at this point. Credit where credit is due, they always tried to fix their mistakes, I just wish there had been less.
I want so badly to increase this rating. I get it shipping is crazy and industries have busy seasons where they’re running behind, I also get switching to a new inventory/shipping system and it can be hard (though judging from reviews they’ve been updating the shipping system for four months now). Everytime I do get ahold of someone they seem sincere. What I don’t think is great is not listing on your website if you’re out of stock of something. This happened with the heater I ordered, I called about a week after the order was complete (charged to my card) but not shipped. They told me they didn’t have any so they ordered one from somewhere else and that would ship to me ~ two week lead time (far cry from their website saying they’ll ship within two days). Their website should reflect their stock. They were apologetic and said they’d actually get one the next day in a shipment and they’d just send me that one - great! It’s been over a week since they said that and it still hasn’t shipped. I called and asked if they could just ship my vapor barrier and tape so I can continue my build and they agreed - great again! I just got the box and they shipped me qty 1 of each when I ordered qty 2 and the receipt shows it should be two as well. They seem well intentioned however they’re just unorganized at this point. I’m
sure they’ll fix my order but at this point I can’t recommend them - at least call ahead and make sure your item is in stock before buying and follow up on shipping. (My shipment receipt shows the heater shipped, it did not, that was expected. Apparently shipping a partial order sends a receipt that everything shipped.)
Fairly good product and friendly people, but they got a few things wrong on our order, and every time I reached out about it - or just had a general question - it was 50/50 whether I'd get a response. That's just not good enough in this day and age.
