Quick answer: A steam shower is a fully sealed, waterproof shower enclosure fitted with a steam generator. It requires a sealed ceiling (slightly sloped), a vapor-proof full-height door, non-porous walls (porcelain, stone, or solid surface), and meticulous waterproofing. Cost is a premium over a standard custom tile shower, driven by the generator plus the sealed enclosure. Infinity Kitchen & Bath (AZ ROC #339999) designs and builds steam showers across Prescott.
A steam shower turns your daily shower into a spa experience — and it's one of the most-requested luxury upgrades we get asked about. But a steam shower is more than a fancy fixture; it's a fully sealed, purpose-built enclosure. Here's what to know before you commit.
A steam shower is an enclosed shower fitted with a steam generator that produces warm, moist vapor. Unlike a standard shower, the enclosure must be completely sealed — floor to ceiling — so the steam stays in and moisture doesn't damage the surrounding bathroom.
Cost depends on the size of the enclosure and the generator, plus the sealing and tile work involved. The steam generator itself is a meaningful line item on top of a standard custom shower build, and the fully sealed enclosure adds labor. We provide an exact figure after seeing your space; in general, a steam shower is a premium upgrade over a standard custom tile shower.
Beyond pure relaxation, steam showers are valued for helping with congestion, sore muscles, and skin. They add a luxury, resort-like feature that stands out — and in our experience, the homeowners who add one rarely regret it.
A steam shower must be enclosed (an open walk-in won't hold steam), and good bathroom ventilation outside the enclosure is important to manage overall humidity. The enclosure also needs to be built to handle constant moisture — which is exactly why waterproofing and the right materials matter so much. This is not a DIY or budget-contractor project.
How much does a steam shower cost?
It's a premium upgrade over a standard custom tile shower. Cost depends on the enclosure size, the steam generator, and the sealing and tile work required. We give you an exact written estimate after evaluating your space.
Can any shower be made into a steam shower?
No — a steam shower must be a fully enclosed, sealed unit, including a sloped sealed ceiling and a vapor-proof door. An open or curbless walk-in shower won't hold steam. The enclosure must also be waterproofed to handle constant moisture.
What surfaces work best in a steam shower?
Non-porous materials: porcelain tile, natural stone (properly sealed), or solid-surface panels. The entire enclosure must be waterproofed behind the surface, since steam will find any weak point.
Are steam showers worth it?
For homeowners who want a spa-like experience, yes. They're prized for relaxation and for easing congestion and sore muscles, and they add a standout luxury feature. They do require a proper sealed build — this isn't a budget or DIY project.
