What 'custom' really means in shower glass

Out-of-square walls, sloped ceilings, fixed bench cutouts, low-iron glass — here's what pushes a project from stock to custom, and what it costs.

Five things that make it custom

Any one of these turns a job into custom work — most projects we install have at least two.

Geometry

Angled walls and sloped ceilings

Knee walls, dormers and out-of-square openings need templates and field measuring instead of stock sizing.

  • On-site template after tile is done
  • CNC-cut to the exact wall profile
  • Heavier hardware to span unusual openings
Glass spec

Low-iron, thick, or coated glass

Standard glass has a green tint; low-iron is crystal clear. Thicker glass adds weight and presence.

  • Low-iron (Starphire / Optiwhite)
  • ½″ glass on large fixed panels
  • Easy-clean coatings for hard water
Cutouts

Notches for benches and niches

A bench, soap niche or wall return all need precise notch cuts in the tempered glass before fabrication.

  • Notches drawn from a paper template
  • No field-cutting once tempered
  • Polished edges on every visible cut
Hardware

Custom hinges and channels

Glass-to-glass hinges, ceiling-to-glass clips and U-channels in unusual finishes all add fabrication time.

  • Glass-to-glass 90° / 135° hinges
  • Ceiling support bars for tall panels
  • Matched finish across hinge, handle, clip
Lead time

Plan for 3–4 weeks

Custom glass is fabricated once we have the template — so timeline depends on when your tile is done, not when you order.

  • Tile must be fully set + grouted
  • Template visit usually 30–45 min
  • Install 3–4 weeks after template
