Thats 15 hours at $100 an hour. We pay generally $75 an hour. (New England)

Determine the approximate time needed times the standard hourly rate and you will have your answer.

I would be very surprised if the new tile matches the old so check the dye lot number. As for labour I have no idea what is fair where you live,

Its a change order so I think that is more than fair.

Ever picked up tile before, loaded and unloaded?

It's more than fair, whether twenty minutes away....or three.

You have to get your act together on this project : )

Check the dye lots.............

It's more in labor and materials, he's not going to do it for free. See if you can calculate the square footage, delivery, and labor costs to determine whether it's fair or not. If you don't think it's fair, then don't do it. Or negotiate with the GC. Keep in mind that change orders are expensive by design, to deter you from wasting the GC's time and opportunity cost of doing another job.

Whether the tile installer is his employee or a subcontractor is irrelevant.

It seems reasonable to me.

When you decide mid stream to add and change, to challenge installations when you did not specify or plan at the start.....as you have been doing with the project? I am surprised it was not double lol.

We have a term for that in this biz...we call it the PITA fee. Go ahead, beat me up.: )

VERY reasonable for such a large change order. But, you are NOT going to get the same shade lot as was used for the rest, so be prepared for that to not match, or choose a different color tile entirely for that whole wall. Which means reworking the shower, and redoing the waterproofing. Which obviously needs fully redoing as they put Ditra inside the shower. I don't think your tile guys are tile professionals.

Mid-change plan and that much work? Yes, 1500 sounds reasonable. And as others have said, be prepared for lot differences in materials.

Sounds reasonable.

Thanks All! And Jan, you’re not that wrong :) I’m doing my best with my adorable but ADHD brain and I try hard to be kind, upbeat, and feed the guys periodically as I do know I can be a bit of a PITA. :)

Fix the waterproofing issue that should have been caught about 5 steps back.

I was just thinking about thta waterproofing too that is why I came back

Waterproofing issue?

Seems very fair with the taller ceiling height and angled cuts for the sloped ceiling.

Thanks. I’m glad it seems fair so good to know. Re: Waterproofing—I’m researching (I consulted with a younger contractor friend) but it seems like my experienced contractor is waterproofing in a legitimate but more “old school” manner? From what I understand it is still within legal standards to use Permaboard on walls as it is waterproof but maybe not preferred to using newer product like Kerdi? Walls are mostly done in bathrooms but I will ask about waterproof plan on floors—Is using Ditra on floors (note: there will be heated flooring) WRONG? Or just less preferred to Kerdi on floor? TIA.

Your research is wrong. This will leak.
