A steam shower is not a regular shower with a steam head added. It’s a sealed glass room, with specific requirements for transom geometry, door fit, glass thickness, and material compatibility — and if any of those are wrong, you get steam leaking into the rest of the bathroom and a generator that struggles to hold temperature.
Lux Glass builds custom steam shower enclosures across Vaughan to true steam-tight standard, fabricated from Starphire low-iron tempered glass on request, and backed by our 5-year workmanship warranty.

The 2026 spa-bathroom: wellness moves in
Steam showers are one of the clearest 2026 design trends in high-end Vaughan renovations. Industry coverage of bathroom design this year repeatedly highlights the move toward home wellness — steam, rainfall, bench seating, layered lighting — and steam is the single feature that turns a shower into a daily-use spa rather than a once-a-month indulgence. For a custom home in Kleinburg or a tear-down rebuild in Thornhill, the steam enclosure is no longer optional; it’s the expected upgrade in the principal ensuite.
What makes a steam shower different
The mechanical and structural requirements that separate a steam-shower enclosure from a regular shower:
- Sealed top with transom. The enclosure must close at the ceiling. We use a fixed-glass transom (a horizontal panel) above the door so steam stays in. Standard frameless showers are open at the top.
- Full-height door, tight tolerances. The door has to close against gasketing on three sides. Standard shower-door tolerances are too loose.
- Sloped ceiling. The ceiling inside the enclosure must slope at least 2° (some specs say 3°) so condensed steam runs to the wall, not onto your head.
- Material compatibility. Wood, drywall, and most paints don’t survive in a steam environment. Tile, stone, glass, and cement-board substrates only.
- Vapour-barrier integration. The waterproofing in a steam shower must extend up the wall and across the ceiling. Our channel placement coordinates with your tile setter’s vapour barrier.
- Steam-generator coordination. The generator (Mr. Steam, Steamist, ThermaSol, etc.) is sized to the cubic-foot volume of the enclosure. We provide the dimensions for your plumber/electrician to spec the right unit.
Glass: standard tempered or Starphire?
For a high-end Vaughan steam shower we strongly recommend Starphire low-iron glass. Standard float glass has a green tint that gets stronger at the edges — and a steam enclosure has more glass than a regular shower (door + side panel + transom), so the green-tint effect compounds. Against a marble feature wall in a $40k+ ensuite, Starphire is the only glass that lets the marble actually read the way you and your designer chose it.
We stock Starphire and bring physical samples to every quoting visit so you can see standard tempered next to Starphire against your own finishes before deciding.
Hardware finishes
We carry every hardware colour and finish available on the market — all in marine-grade or 316 stainless steel for steam-environment durability. Door pulls, hinges, transom clips, and channels all match through the enclosure.
Where we install in Vaughan
We work across Vaughan — Kleinburg, Thornhill, Maple, Woodbridge, Concord, Vellore Village — and the surrounding cities of Richmond Hill, Aurora, King City, Markham, and Toronto. Steam enclosures are particularly popular in Kleinburg custom-home builds and Thornhill principal-ensuite renovations.
Our process for a steam shower
- Pre-build consultation. Ideally we meet with you and your contractor before tile is set, so vapour barrier, ceiling slope, and substrate can be coordinated.
- Quotation. Itemized written quote with options for Starphire upgrade and hardware finish.
- Templating. After tile is finished and ceiling slope is set, we laser-template door, side panels, and transom.
- Fabrication. 10–14 business days for tempering, edge finishing, hardware drilling, and gasket fitting.
- Installation. Typically 30 minutes to 3 hours on-site by our own installers — never subcontractors. We install the enclosure, door, transom, and gasketing.
- Commissioning. We test the door seal and transom fit before sign-off.
- 5-year workmanship warranty in writing.
What a custom steam shower enclosure costs in Vaughan
- Custom steam shower enclosure (door + side panel + transom): ~$2,100–$3,300 installed.
- Starphire low-iron upgrade: adds exactly 35% to the glass cost.
- Steam generator and plumbing/electrical: not included — coordinated with your plumber and electrician.
Final pricing depends on dimensions, configuration, hardware, and Starphire choice. Fixed written price, no surprise extras.
Frequently asked questions
What’s the difference between a steam shower and a regular shower with a steam feature?
A true steam shower is a sealed enclosure: glass to the ceiling (with a transom), sloped ceiling inside the enclosure, vapour-barrier integration, full-height gasketed door, and steam-rated materials throughout. A “shower with a steam head” leaks steam into the bathroom and won’t hold temperature long enough to be useful.
Can you retrofit my existing shower into a steam shower?
Sometimes. The two biggest blockers are: (1) is the ceiling inside the enclosure properly sloped, and (2) does the existing waterproofing extend up the walls and across the ceiling. If both are met, we can usually swap the glass to a sealed enclosure. We’ll assess on-site.
What steam generator do I need?
The generator is sized to the cubic-foot volume of the enclosure, the wall material (tile/stone vs. tile-on-cementboard), and ceiling height. Mr. Steam, Steamist, and ThermaSol all publish sizing tables. We provide the enclosure volume for your plumber/electrician to size the unit; we don’t supply the generator itself.
Should I choose Starphire glass for a steam shower?
For a high-end installation against light stone or designer finishes — yes. A steam enclosure has more glass than a regular shower (door, side panels, transom), so the green tint of standard glass compounds. Starphire is the difference between seeing your design and seeing it through a green filter. Read our full Starphire low-iron glass guide for the visual comparison and pricing examples.
How thick is the glass?
Steam enclosures use 3/8″ (10mm) tempered standard. Door panels and transoms over 1.2 m wide go to 1/2″ (12mm). All glass tempered to CAN/CGSB-12.1.
What’s your warranty?
Five-year workmanship warranty in writing on every Lux Glass steam enclosure. Hardware and gasketing carry the manufacturer warranties.
