Best VEVOR Steam Shower Generators
Part of our Home Spa & Outdoor guides.
A steam generator turns a sealed shower into a steam room. The key spec is room volume in cubic feet: too small a generator never gets the room steamy. VEVOR lists recommended volumes per model, which makes sizing straightforward.

Sizing rule
Calculate volume: length x width x ceiling height in feet. Tile, stone and glass absorb heat, so size up one step for fully tiled rooms, and again for high ceilings or an exterior wall. Calculator: steam generator size calculator.
Electrical and plumbing
Steam generators run on 240 V with large breakers (VEVOR's 15 kW model lists 60 A). They need a cold water supply and a drain, and are mounted outside the shower within the distance the manual allows. Hire a licensed electrician.
Frequently asked questions
Can any shower be a steam shower?
Only if it's fully enclosed to the ceiling, with a vapor-proof door and a sloped ceiling to stop dripping. Standard glass doors with gaps let the steam escape.
How long does a steam generator take to heat up?
VEVOR states its 6 kW units reach full steam in about 7-10 minutes from cold.
