The tile is set, the grout is curing, and the homeowner walks in and says, “I thought the herringbone was included.” Now you are eating two extra days of labor, a pallet of cut waste and a very awkward conversation. That is how tile change orders usually go wrong: not with one big blow-up, but with a dozen small “sure, we can do that” moments that never made it onto paper.
Tile is one of the easiest trades to lose money on. The material is expensive, the labor is slow, the layout is personal, and everything underneath it is a mystery until you start demo. If you are a GC, a sub or a one-man tile outfit, this is what goes wrong and what it costs.
What unwritten tile changes really cost you
A tile job does not fail loudly. It bleeds. A pattern upgrade adds setting time. A bigger format needs a flatter floor. A niche gets added late and the waterproofing has to be redone. Each one feels small in the moment, so nobody writes it down. Then the invoice arrives and the owner compares it to the original number, not to the work that actually happened.
The real costs stack up like this:
- Unpaid labor. Setters are paid by the day whether or not the owner agreed to the extra work.
- Dead schedule. A tile change that lands after the next trade is booked pushes your own crew and everybody behind you.
- Eaten materials. Reordering a different tile, or an extra box for a new pattern, comes out of your pocket if nothing was signed.
- A damaged relationship. Owners remember the surprise charge long after they forget the nice backsplash.
None of that needs a villain. It only needs a handshake and a short memory.
6 tile change order mistakes that cost contractors
1. Treating a layout change as “just a quick tweak”
Moving from a straight lay to a diagonal, herringbone or offset pattern is a different job. Waste goes up, cuts go up and setting time can double. If you say “no problem” on site, you have quietly rewritten your price. Write the pattern, the waste factor and the added hours into a change order before the first tile is cut.
2. Swapping tile without pricing the whole chain
The owner picks a heavier or larger-format tile and you only price the material difference. But large-format tile often needs a flatter substrate, a different thinset, back-buttering and extra labor to handle it. Miss those and the material swap becomes a loss. Price the tile, the setting materials, the prep and the labor together.
3. Finding a bad substrate and fixing it for free
You pull up old flooring and find soft subfloor, an out-of-plane wall or a shower pan that was never sloped right. You fix it because the tile cannot go over it. That fix is a change order, not a favor. If you did not document it with photos and a signed approval, expect the owner to say it should have been in your original bid. This is the same trap covered in our guide to hidden damage change orders.
4. Adding niches, benches and accent strips by text message
Shower niches, benches, mosaic accent bands and heated floor mats are the classic late add. A text that says “yes do the niche” is not a price and not a scope. It will not hold up when the owner questions the number. Every add-on needs a written scope, a dollar amount and a signature.
5. Ignoring the cure and lead-time ripple
Tile changes ripple into time. A different tile may have a three-week lead. A waterproofing redo means another cure window before you can set. Plumbing trim, glass and vanities all wait on you. If your change order only covers dollars and not days, you will be the one blamed for the delay you did not cause. Our post on change order time extensions shows how to put the days in writing.
6. Billing the extra work after the grout is done
The longer you wait, the less leverage you have. Once the tile is set and the owner has moved in mentally, every extra dollar feels like a surprise. Retroactive paperwork is the weakest position to negotiate from, and our look at retroactive change orders explains why they so often go unpaid.
A real-world example: the $1,900 shower niche
A tile sub quoted a bathroom at a fixed number. Midway through, the owner asked for a recessed niche and a mosaic border, and the sub agreed out loud. The niche needed framing, extra waterproofing, 14 more setting hours and a special trim piece. At the end, the sub invoiced $1,900 more. The owner pushed back: nothing in writing, and she believed it was part of the original price. The sub took a $1,100 haircut to keep the peace. A one-page change order, signed the day she asked, would have saved every dollar of that.
The right way to handle tile change orders
The fix is boring and it works: stop work on the change, write it down, price it, get it signed, then proceed. Every tile change order should include:
- A plain description of what is changing (pattern, format, area, add-on).
- Material cost, including waste and extra boxes.
- Labor hours and rate, including prep and any waterproofing.
- Markup and tax if they apply.
- Any schedule impact, in days.
- The new contract total and a signature line.
You have two free ways to do it, and they work equally well. Pick the one that fits how you run jobs.
Option A: the free Excel template
If you like a spreadsheet you can keep on your own computer, grab the free Excel change order template. Line items, markup, tax and the revised contract value are calculated for you, and the built-in log lets you track every tile change on a job. It is a solid choice for shops that already live in Excel.

A professional, auto-calculating change order spreadsheet — line items, markup, tax and your revised contract value all worked out for you, plus a log to track every change order on the job. Free to download and use on any project.

If you would rather get it signed from a phone while you are standing in the bathroom, use the free ChangeOrdersPro tool. Describe the change, add the price, send it, and the owner signs on their phone. The contract total updates itself and you have a dated record. Curious how both can be free? See why it is free.
Whichever you pick, the habit matters more than the tool. Never set a tile that was not approved on paper.
A quick checklist before you touch the trowel
- Did the owner approve the new tile, pattern or add-on in writing?
- Is the price signed, with materials, labor and prep separated out?
- Have you photographed any substrate problems before you cover them?
- Does the change order include added days if lead time or cure time is affected?
- Is the signed copy saved where you can find it at final payment?

Create a free change order →Stop paying for changes you never approved
Every tile job has at least one change. The only question is whether you get paid for it. Put it on paper, get a signature, and keep your margin where it belongs. Use the free change order spreadsheet if you want a file on your computer, or create a free digital change order if you want it signed on site. Both take a few minutes, and both are cheaper than one eaten shower niche.
Frequently asked questions
Do I need a change order for a tile pattern change?
Yes. A pattern change usually means more waste, more cuts and more setting time, so it changes your cost. Write the new pattern, the added hours and the extra material into a change order and get it signed before work starts.
What if I find a bad substrate after demo?
Stop, photograph it, and write up the repair as a change order with a price and a signature before you proceed. Unapproved fixes are the hardest extra work to get paid for.
Is there a free Excel template for tile change orders?
Yes. The free Excel change order template calculates line items, markup, tax and your revised contract total, and includes a log to track every change on the job. You can download it at no cost and use it on any project.
Can my client sign a tile change order on their phone?
Yes. The free ChangeOrdersPro digital tool lets you send a change order and have the client sign from their phone, with the contract total updated automatically.
Is this legal advice?
No. This is general information, not legal advice. Requirements change and vary by state and contract, so confirm the current rules with your state's licensing board or a licensed attorney before relying on them.
