## What field measurements must a tile setter verify right after bathroom?

Completing **a bathroom** is only half the job for a solo **tile setter**—the fifteen minutes before you roll the truck off the driveway determine whether **how to invoice after bathroom tile installation** turns into same-day cash or a 30-day collection chase. Before generating the final PDF invoice for **bathroom**, verify four site specifics:

1. **Final Installed Sq ft tiled Count:** Check whether the completed **bathroom** matched your initial estimate (~**18 hours** at **$100/hr**) or required additional *Substrate — cement board, waterproofing* and *Floor tile set*.
2. **Material & Supply Consumption (~$882):** Confirm every unit of **Porcelain/ceramic tile, Schluter Kerdi/Ditra membrane, modified thin-set mortar & epoxy grout (Line 22)** used on the **bathroom** ticket so your **25%** markup and **$$80** trip fee are captured.
3. **Timestamped Close-Out Photos:** Snap clear photos of the finished **bathroom** showing compliance with **TCNA Handbook / ANSI A108 mortar coverage (95% wet areas), waterproofing membrane & movement joints**.
4. **Cleanup & Disposal Verification:** Make sure *Old floor tear-out* is listed so you avoid **forgetting to bill the $80 trip/setup charge, unrecorded Old floor tear-out, and Porcelain/ceramic tile, Schluter Kerdi/Ditra membrane, modified thin-set mortar & epoxy grout (Line 22)**.
