Why name the waterproofing system?

Because it's the part of a shower that decides whether it lasts twenty years or leaks into the ceiling below, and it's completely invisible once tiled. Naming the system — and photographing it before tile goes on — is both a technical necessity and your best answer to a cheaper bid.

How much waste should I quote on tile?

10% for a straight-set standard size, 15–20% for diagonal, herringbone, or large-format, and more for small mosaics and complex layouts. Show material quantity separately from installed area so the number reads as arithmetic, not padding.

Should pattern complexity change the labor rate?

Yes, significantly. Herringbone, chevron, and large-format tile requiring back-buttering and leveling clips take far more time per square foot than a straight-set subway. Band your labor rate by pattern rather than pretending square footage tells the whole story.

Photograph the waterproofing before tile

It’s probably the single most important layer, and the only one nobody can ever inspect again once it’s covered. Photos of the finished membrane, the corners, and the pan are your proof of a correct installation for as long as that shower’s around.

Say what happens if customer-supplied tile runs short

Customers routinely order without accounting for waste. One line — shortages and breakage are the customer’s responsibility, and re-mobilization is billable — turns a stalled job into a managed one instead of a fight.
