Plan the attachment before the tile
A frameless shower looks simple because most of its work is hidden. Wall backing, waterproofing, curb geometry, slopes, niches, benches, ceilings and door swing should be coordinated before tile closes the assembly.
The goal is not to attach wherever space remains. It is to establish safe hardware zones without compromising the waterproofing or forcing awkward glass geometry later.
Measure the finished condition
Final fabrication dimensions normally follow the completed tile and other critical finish planes. The field measure records out-of-plumb walls, level variation, curb and bench geometry, required clearances and the exact hardware arrangement.
Small dimensional errors repeat at glass edges and joints, where they are difficult to disguise. Fabrication should begin only after the opening and selected hardware agree.
Choose glass and hardware as one system
Thickness, tempering or lamination, standard clear or low-iron appearance, privacy, coatings, hinges, channels, clamps, pulls and seals affect one another. Steam showers add ceiling, ventilation, transom and sealing questions.
Safety-glazing requirements and the manufacturer’s tested limitations remain part of the selection. The project team should confirm the applicable code and installation path rather than relying on a generic catalog image.
