What a Steam Shower Actually Is
A steam shower is a fully enclosed shower cabin with a built-in steam generator, a waterproof ceiling, and a sealed glass door. Flip the control to steam mode, and the generator vaporizes water into the enclosure until the cabin fills with thick, wet heat — typically 110°F to 118°F at around 100% humidity. Unlike a traditional sauna (dry heat, 170°F+), steam bathing stays at a lower temperature but saturates the air, which is why your skin feels soaked in minutes.
Every unit in this collection is a self-contained steam shower — the cabin, generator, plumbing fixtures, glass door, and controls ship together as one system. You don't buy a generator separately and tile a room around it. You install the unit, hook up water, drain, and a 220V line, and it's ready. That's the whole appeal versus a custom tiled steam room: no waterproofing contractor, no steam-proof door search, no tile grout failure two years in.
Types of Steam Showers
Shape dictates where the unit fits and how you use it. Four main configurations show up in our lineup:
-
Corner steam showers — Diagonal footprint, two glass walls, pentagon-shaped base. Designed to slot into a 90-degree wall corner. The most common configuration and the most space-efficient for small bathrooms. Examples: Mesa WS-300, WS-301, WS-302, WS-9090K.
-
Walk-in rectangular steam showers — Straight back wall with a single-panel or bypass glass door. Installs against any flat wall. Wider interior and more natural movement inside. Examples: Mesa 500XL, Mesa 802L, Ariel Platinum DZ963F8.
-
Neo-angle and specialty shapes — Angled front glass (neo-angle) for a more sculptural look in a corner. Ariel Platinum DZ959F8 and DZ961F8 fall here.
-
Steam shower tub combos — Full steam cabin with an integrated whirlpool or air-jet tub inside the footprint. Bathe, then shift to steam, then cold rinse — all in one unit. See the dedicated combo collection for every model we stock.
The Two Brands We Carry
We stock steam showers from two manufacturers, and the distinction between them is real. Spend 10 minutes on each product page and you'll see where the price delta comes from.
Mesa is the volume workhorse. Italian-designed, 3kW steam generator standard across the line, tempered glass (5mm typical on corner units, 6mm on walk-ins), chrome fixtures, and the full feature stack: rainhead, handheld shower, 6 acupuncture body jets, FM radio, aromatherapy dispenser, and LED chromotherapy lighting. The WS series spans more than a dozen active SKUs — the 300-series corner units, the 500/600/700/800-series walk-in and combo units, and the 9090 entry-level corner. Browse the full Mesa steam showers lineup for every model.
Ariel Platinum is the design-forward option. Thicker 8mm tempered glass on most models (versus Mesa's 5–6mm), sharper architectural lines, and model-specific upgrades like dual ceiling rain panels, computer-controlled touchscreen panels, and telephone/Bluetooth integration. The DZ series — DZ934F3, DZ956F8, DZ959F8, DZ961F8, DZ962F8, DZ963F8, DZ972F8, DA333F8 — leans toward the higher end of the price band. See the full Ariel Platinum collection for specs and color options (most ship in white or black).
Short version: pick Mesa if you want the steam experience with full features at the lower price. Pick Ariel Platinum if thicker glass, more refined styling, and larger cabin dimensions matter to you.
Features Worth Understanding Before You Buy
Steam generator wattage. Mesa and Ariel Platinum both run 3kW generators in their standard units. That's enough to fill cabin volumes in the 40–60 cubic foot range in about 5–8 minutes, with a run time typically capped at 20 minutes before auto shutoff. Larger cabins or high-ceiling installs benefit from bigger generators — check the spec sheet on the specific product page.
Glass thickness and color. Mesa corner and walk-in units ship with 5mm or 6mm tempered safety glass in clear or blue tint. Ariel Platinum typically uses 8mm tempered glass. Thicker glass is heavier, feels more solid when the door closes, and dampens sound slightly. Blue glass adds privacy and reduces visual clutter; clear glass keeps the bathroom feeling more open.
Ceiling design. This is where high-end units separate from entry-level. The Ariel Platinum DZ972F8 has a dual overhead rain panel plus a backlit ceiling light panel. Mesa 500-series and 800-series walk-ins include an overhead rainhead and ceiling lighting. Corner models typically skip the rainhead in favor of a handheld plus body jets.
Rainhead vs handheld. Almost every unit includes both — ceiling-mounted rainhead for the overhead drench, and a handheld on a slide bar for rinsing. The rainhead is the feature people use; the handheld is the feature people need.
Extras. FM radio with speakers, aromatherapy essential oil reservoir, chromotherapy LED mood lighting, foot massage reflexology points on the floor tray, and body jets for acupressure — these come standard on nearly every Mesa and Ariel Platinum steam shower in this collection. They're genuinely used, not marketing filler.
Installation Requirements
Before you pick a model, confirm you can install one. Three systems need to be ready:
Plumbing: Hot and cold water supply lines (standard 1/2" lines), a drain (2" P-trap), and a pressure requirement usually between 30 and 70 PSI. Most homes are already in spec. If you're replacing a standard shower, the supply and drain may already be in the right location — if not, plan on a plumber rerouting lines.
Electrical: Steam generators need a dedicated 220V/240V circuit with a 20–30A breaker, hardwired by a licensed electrician. This is the step most DIY buyers overlook. The generator itself is plug-and-play once wired, but the circuit has to be installed before the unit arrives.
Ventilation and waterproofing: Because these units are self-contained with sealed tops, you don't need to waterproof the surrounding bathroom the way you would for a custom tiled steam room. That's the biggest advantage of a prefab unit. You do still want a bathroom exhaust fan to clear residual humidity after sessions, and the sub-floor should be water-resistant (tile, LVT, or a waterproofed substrate).
Bathroom and Room Fit
Measure before you shop. Corner units typically need a 36"–48" diagonal corner. Walk-in rectangular units run 47"–60" wide, 32"–36" deep, and around 85" tall. Tub combos push 60" wide or more. Check your doorway too — some units ship in pre-assembled panels that need to clear a 30" bathroom door. Product pages list exact dimensions and shipping package sizes.
If your bathroom is tight or your ceiling is under 84", a corner unit is the move. If you have a dedicated master bath with space to plan around, walk-ins or combos give you more interior room. Shopping matching tubs, vanities, and fixtures alongside a steam shower helps you spec the room as a whole if you're doing a full remodel.
How to Choose
Work through it in this order: available space and corner vs flat wall → budget range (Mesa entry around the WS-9090 vs Ariel Platinum upper end on the DZ972F8) → must-have features (rainhead ceiling, aromatherapy, tub combo) → left-hand vs right-hand orientation if the unit offers it (WS-802L, WS-905, DZ959F8, DZ961F8 all have handed configurations — confirm which side your plumbing is on before ordering).
