The VEVOR 12KW Steam Shower Generator (model DO-120) is the unit that makes the steam for a home steam shower or steam room. It sits outside the enclosure, heats water in a tank and sends steam in through a nozzle. This page explains what its specifications mean and what to confirm before planning an installation.
What a steam generator does
A steam generator is separate from the shower cabin itself. Water enters a tank, heating elements bring it to steam, and a pipe carries the steam to a nozzle inside the enclosed space. A temperature sensor in the room reports back to the controller, which adjusts the heating to hold the setting you chose.
VEVOR says this model heats in segments, which it states delivers steam within about five minutes. Segmented heating typically means the elements switch on in stages rather than all at once, which helps the unit reach temperature and then hold it.
Power, voltage and room size
VEVOR specifies the power as 12 kW on two-phase 230V AC at 60 Hz, with a 60A wire breaker. That is a substantial electrical load, much more than a typical plug-in appliance. In most homes a unit of this size needs its own dedicated circuit, installed to local electrical codes.
VEVOR lists the applicable space as an acrylic steam room of 424 cubic feet. Steam output has to match the volume of the enclosure. A room that is too large, or has tile, stone or glass surfaces that soak up heat, typically needs more capacity than the same volume in acrylic.
Controls, timer and temperature range
The controller uses smart touch controls. The temperature range is 77 to 131°F (25 to 55°C), and the operating time can be set from 10 minutes to 24 hours. The long upper limit is a maximum setting, not a recommended session length.
Protections and tank construction
According to VEVOR, the generator includes protection against overheating, water shortage and overpressure. It also has an automatic drainage system, which empties the tank after use so water does not sit inside.
The liner is stainless steel, with a Q235B steel shell. VEVOR says the tank has an integrated magnesium rod, which is a sacrificial part designed to take on corrosion in place of the tank, and that the heating elements are certified 316 stainless steel. The brand says these choices help keep steam clean and prolong the unit's life.
What is in the box
The package includes a controller, connection line, safety valve, temperature sensor, electric valve, install hanging board, steam nozzle and instructions. The generator measures 21.3 x 7.5 x 19.3 inches (about 54 x 19 x 49 cm) and weighs 32.6 lb (14.8 kg), so it hangs on a wall using the supplied board and needs a firm mounting surface.
Who it suits
It suits a household building or upgrading a sealed acrylic steam enclosure and wanting a generator with a timer, a set temperature and automatic drainage. VEVOR describes it as made for private residences with straightforward installation, but a 12 kW electrical supply and water connection are jobs for a qualified electrician and plumber.
What to check before you buy
- Enclosure size and material: compare your room's volume and surfaces with the 424 cubic foot figure.
- Electrical supply: confirm that your panel can provide the two-phase 230V supply and 60A breaker, and follow local electrical codes.
- Water supply and drain: check where the water line, drain and safety valve will connect.
- Mounting spot: the unit needs a location outside the steam room, with space for service access and ventilation as the manual describes.
- Water quality: hard water typically leaves mineral scale in any steam tank, so check the manual for descaling advice.
- What is included: compare the package list with what your installer needs.
