Match the evidence to the product.
A component listing or material test applies to its identified product and tested construction. It does not automatically certify a completed TRÜbath shower-pan assembly. Confirm the selected base, porcelain, finish, drain and installation system before fabrication.

The listing addresses the identified manufacturer components. Its ASTM C627 floor-system result used standardized 8 × 8 inch tiles; it is not a test of every porcelain-clad TRÜbath configuration.
Application: Use only when the supplied component is covered by the listing and installed to the manufacturer’s instructions and applicable codes. Project-specific cladding, adhesive, drain and field waterproofing still require review.
Confirm the exact manufacturer, product code, finish and thickness. ANSI A137.3 addresses gauged porcelain tiles and panels/slabs; ANSI A137.1 addresses ceramic tile, including porcelain. The applicable category depends on the selected product.
Porcelain classification uses water absorption of 0.5% or less under ASTM C373. This is a classification criterion, not a published measurement for every finish shown on this website.
Shower-floor suitability: A DCOF result belongs to its tested specimen and method. It does not establish slip resistance or safety for every finished shower pan, wet-barefoot condition, slope or maintenance condition. Product-specific evidence and manufacturer suitability confirmation are required.
Verify the pan model, finished dimensions, curb and drain position.
Confirm the exact porcelain and its intended shower-floor use.
Match any test report to the actual material, finish and construction supplied.
Confirm the approved setting material, sealant and waterproofing system.
Obtain the warranty applicable to the supplied product and installation. A component warranty is not a blanket warranty for the finished assembly.
Composite wall-panel mechanical or fire tests are not evidence of shower-pan performance. Original reports retain their original issuer, client and specimen identity. This page does not reproduce restricted laboratory reports or claim a finished-assembly certification.
