Ceramic Tile

In Plain English

Fired clay tiles used on floors, walls, and counters that are durable and easy to clean.

Definition

Ceramic tile is a fired-clay product used for floor, wall, and countertop surfaces. It is manufactured in glazed and unglazed varieties and rated by hardness (PEI rating), slip resistance (COF), and water absorption. Ceramic tile is set in a mortar bed or thin-set adhesive and finished with grout between joints.

Why It Matters in Bidding

Tile is a labor-intensive finish where the setting method, substrate prep, and pattern complexity often outweigh the material cost, so estimators price installation and waste carefully rather than by simple square footage. PEI hardness, slip resistance, and water-absorption ratings dictate which product satisfies the spec, and missing a rating requirement can force a costly substitution after award.

Example

An estimator pricing a restroom tile package adds waterproofing membrane, a higher waste factor for a diagonal pattern, and labor for the schluter edge trim, rather than quoting only the per-square-foot tile material.

Frequently Asked Questions

Setting tile involves substrate prep, waterproofing or backer board, thin-set application, precise layout, cutting, grouting, and sealing. Patterns, large-format pieces, and wet areas multiply that labor. Estimators who price only the per-square-foot material badly understate the line item, since installation and prep typically drive the real cost.
Check the PEI hardness rating for the expected traffic, the slip-resistance or coefficient of friction for wet and accessible areas, and water-absorption class for exterior or freeze conditions. Matching these to the spec prevents quoting a product that fails compliance and triggers a substitution and rework after the bid is awarded.
Waste depends on pattern and room geometry; straight layouts in simple rooms need less, while diagonal patterns, large-format tile, and many cuts around fixtures require more. Estimators add a waste factor plus attic stock for future repairs and account for dye-lot matching, since reordering later may not match the original batch.
