The finish-material pre-purchase check
A quantity estimate is useful only when its measurements and installation assumptions match the job.
Check the room and every unit
Re-measure length, width and wall height. Confirm that room dimensions are feet and tile dimensions are inches. Sum door and window areas for paint; separately sum widths where base trim is absent. Do not deduct wall openings from the floor.
Check the actual products
Confirm tile dimensions, grout spacing, tiles per box, price per box and the intended lot. Enter the paint manufacturer’s coverage and planned coats. Verify actual trim stock lengths before buying; linear-foot estimates do not optimize cuts from stock.
Check the layout with the installer
Compare both tile orientations and the approximate centered edge sizes. No perimeter movement gap, irregular floor shape, herringbone, diagonal pattern or reusable offcut is modeled. Verify substrate, flatness, moisture, waterproofing, transitions and movement requirements with a qualified installer.
Check the handoff
Name the room, review every entered price and export a JSON backup. Browser saves are optional, local and not automatically backed up. Shared links contain measurements and prices but not the project name. Include the assumptions and unresolved installation questions with any printed sheet.
