Custom Shower Enclosures

A steam shower is a fully enclosed, top-to-bottom sealed wet room operating at near-100% humidity and temperatures up to 118°F. The glass needs to extend to within 6" of the ceiling, the door needs to seal at the top with a transom or flipper panel, and the enclosure needs a slight inward ceiling slope (1/2" per foot minimum) to channel condensate back toward the floor rather than dripping on the bather.

Hardware in steam showers takes more abuse than in any other residential glass application. Standard residential hinges and brackets will pit and corrode within three to five years. We spec 316 stainless steel hardware (not 304) for every steam shower — the molybdenum content in 316 resists the chloride attack that develops in repeated high-humidity cycling. CRL's Pinnacle stainless line and FHC's Stainless Series both qualify; we won't substitute lesser-grade hardware even when a homeowner pushes back on cost.

Glass thickness for steam: 1/2" tempered minimum on door panels because of the transom seal weight loading and the door height (typically 84-90"). Low-iron Starphire is strongly recommended because steam condensate on standard green-tinted glass shows mineral spotting more aggressively.

The steam generator's vapor outlet placement matters for glass: we coordinate with the plumber to ensure the steam head is not directly aimed at glass-to-glass joints, which can degrade silicone seals over years of thermal shock.

Curbless showers are now the dominant primary-bath design in NJ new construction and high-end remodels. The continuous tile floor reads as more open and spacious, satisfies accessibility requirements (ADA-compliant zero-threshold), and eliminates the trip hazard of a 4-6" curb. The engineering tradeoff is water containment — without a curb to define the wet zone, the glass enclosure and the floor slope have to do all the work.

Floor slope to drain: minimum 1/4" per foot per industry standard. We measure the existing slope on the tile contractor's mortar bed before scheduling the glass and won't proceed if the slope is insufficient — water that doesn't drain will pond, migrate under the glass, and end up on the bathroom floor regardless of how the glass is sealed.

Glass-to-floor detail: 3/8" to 1/2" gap with a polycarbonate sweep that flexes to follow the floor slope. We do not silicone the glass to the floor on curbless because thermal movement will crack the silicone and create a permanent leak path; the sweep is the dynamic seal.

Linear drain placement: at the entry edge of the shower (parallel to the door opening) is the contemporary preference and works well; at the back wall is the traditional placement. Either works for water management as long as the slope is correct and the glass is positioned to contain the spray pattern.

Every glass shower develops hard-water spotting and soap scum buildup over time. EnduroShield is a fluoropolymer surface coating applied to the glass before installation that bonds at the molecular level and creates a hydrophobic surface — water sheets off rather than beading, and mineral deposits don't adhere. Ten-year manufacturer warranty on residential applications.

The cost is roughly $8-12 per square foot of glass surface. For an average 60-square-foot shower enclosure that's $480-720 — meaningful, but compared to the labor and material cost of replacing pitted glass in five years, a strong value. We apply EnduroShield in our shop before delivery so the coating is uniform and uncontaminated by site dust.

Alternative coatings (Showerguard, Diamon-Fusion) are similar in performance and price. We default to EnduroShield because it's the longest-standing product and the warranty service is reliable.

Maintenance: any coated shower glass should be squeegeed after each use to extend the coating life. The coating is not a permanent fix — it delays mineral buildup but doesn't eliminate it forever. Most coated showers we install need recoat or replacement at 8-12 years; uncoated glass shows visible degradation at 2-4 years.

Euro-style frameless walk-in showers are the high-design configuration: three to five glass panels meeting at 90° or 135° corners, structural-silicone glass-to-glass joints with no vertical metal posts, and a single pivot or sliding door. The visual is a continuous wall of glass. The engineering is precise CAD layout, perfect glass fabrication tolerances (+/- 1/16"), and silicone joints that have to carry load.

Structural silicone joints between glass panels use Dow 995 or equivalent high-modulus silicone with a minimum 3/8" bead width and full-height application. The joint carries both gravity load (each panel's weight transfers to adjacent panels) and shear load (door operation forces transmit through the panel system). We don't substitute lesser silicones on these joints — failure mode is sudden and catastrophic.

Top channel vs no top channel: a continuous U-channel at the ceiling line increases panel stability and is required on door-panel configurations over 90" tall. For purely fixed-panel configurations under 84" tall we can omit the top channel for a cleaner aesthetic, but the bottom U-channel and structural silicone joints have to do more work and the glass thickness goes up to 1/2" minimum.

Bench and niche coordination: when a stone bench or tile-lined niche intersects a glass panel, we cut and fabricate the glass around the obstruction with a notch or step. Every notch increases stress concentration and requires heat-soak treatment on the tempered panel. We coordinate the bench and niche locations with the tile contractor before glass fabrication.
