You can tell the difference on the first ladle. A heater with a shallow rock tray gives you a sharp hiss and a wave that stings, then it is gone. The Revive holds 200 lbs of stone in a tall tower, so the water finds mass instead of metal, and the löyly comes back softer, wetter and longer.
Homecraft’s stated reason for the design is element life. The heating rods sit inside a protective air-flow chamber rather than in the splash zone.
The thing nobody tells you about rock
Rock quantity is not a detail, it is the heater’s performance. The Revive takes 7 boxes at 35 lbs each. Six boxes leaves the tops of the elements exposed, and we have watched that play out on a real install. Order seven.
Stack it loose and high, never tight and low. Big stones on the bottom, smaller on top, gaps everywhere so air can climb through the chamber. Packed too tight, the heat has nowhere to go and the high limit switch trips. Rinse them before the first fire, and pull the cracked ones once a year.
Which output fits your room
Measure length by width by ceiling height. These ranges come from the Revive install manual. If the room has a glass door, tile, or an uninsulated wall, size up.
| Model | Output | Room volume |
|---|---|---|
| Revive 6 kW | 6,000 W | 250 to 300 cu ft (7.1 to 300 cu ft) |
| Revive 7.5 kW | 7,500 W | 300 to 370 cu ft (8.5 to 371 cu ft) |
| Revive 9 kW | 9,000 W | 360 to 450 cu ft (10.2 to 448 cu ft) |
Electrical
| Model | 240V single phase | 208V three phase |
|---|---|---|
| 6 kW | 25 A, 40 A breaker, #8 wire | not listed |
| 7.5 kW | 31.3 A, 40 A breaker, #8 wire | 20.9 A, 30 A breaker, #8 wire |
| 9 kW | 37.5 A, 50 A breaker, #8 wire | 25 A, 40 A breaker, #8 wire |
Supply conductors need to be 14 AWG or larger rated for at least 105 C. Skip the GFCI breaker unless your code calls for one. A certified electrician has to make the connection or the warranty is void.
What ships with it, and what does not
- Heater: 14 x 14 x 36 inches, stainless throughout, high-limit reset switch built in.
- Controls, sold separately: a TKE2-2 contactor box (indoor or weatherproof outdoor) plus a touchpad. The touchpad mounts in a two-gang box outside the room and runs a 60 minute cycle, adjustable 25 to 90 C.
- Rock, sold separately: 7 boxes. Add it here so it ships together.
- Clearances: 3.5 inches to combustibles, 42 inches from the top of the heater to the ceiling. Secure it to the floor and the back wall with the supplied brackets, and fit the heater guard.
- Temperature sensor: mounts in line with or directly above the heater, 3 to 4 inches down from the ceiling. Put it anywhere else and you will trip the high limit.
Where yours actually ships from
We source this line through a New York warehouse whenever the size you want is on the floor there, which covers the fastest-moving models. Anything not in stock is built to order in Surrey and crosses as Canadian origin under USMCA, so there is no import duty either way, just a longer window. We read all three supply feeds every morning, so ask before you book an electrician and we will tell you what is really on the floor today.
Wi-Fi, now that it exists
Homecraft spent most of 2025 testing a Wi-Fi touchpad and we spent most of 2025 telling customers it was not ready. It is now, and it is stocked in North America. Phone control for start, stop and temperature, plus calendar scheduling so the room is at temperature when your session starts rather than forty minutes after.
Installation
Certification and warranty
CSA and UL certified, ETL listed for permanent installation, splash-proof construction with the conducting parts protected against water. Two year manufacturer warranty when installed and used to the manual. Homecraft’s manuals treat heating elements as a consumable and exclude them, so ask us to get element coverage confirmed in writing on your order rather than assuming it. Improper stones and non-certified electrical work void the cover.
Not sure between this and a HUUM?
It is the most common question we get on this heater, and the honest answer depends on how you bathe. Send us your room size, ceiling height, wall build and panel capacity, and we will tell you which one we would put in that room. Call (844) 565-1113.

Write a reviewThe Revive is performing perfectly. We had wanted a mechanical control, but the digital unit was the only one available – that was our only disappointment.
We were impressed by the quality of your service – the best price, the fastest delivery ... and excellent customer support every step of the way. Thank you.
This sauna heater is a real GameChanger. The one I had before was not getting my barrel sauna nearly hot enough. After having installed this one I feel like I have a true sauna now. Could not be any happier! Highly recommend!
