Specification guides, written by the people who make the parts

Five guides covering the questions that come up before a bath safety order: what the code actually requires, what holds a load, which alloy survives which environment, and how to tell a factory from a middleman.

Accessibility

ADA grab bar height requirements

The 33–36 inch rule measured to the centreline, plus length and position tables for toilet, shower and tub installations.

8 min · §609, §604.5, §608.3
Load & structure

Grab bar load rating: what 250 lb means

Why bars pull out of walls that were never designed for them — substrate load tables and the three variables that decide the assembly.

7 min · §609.8
Shower seating

Folding vs fixed shower seats

Which type passes ADA, which one survives daily use, and why the hinge and the wall matter more than the seat surface.

8 min · §608.4
Material selection

304 vs 316 stainless in bathrooms

Both are called stainless, but only one survives chlorides. Composition, environments, salt spray and the magnetism myth.

7 min · ASTM A240
