Can you remind us again of what the airborne chemicals were?? Thanks, K

They newer photos of your paint look pretty close to my kitchen and family room walls. :-) Don't worry about the mini-novel. It's the cheapest therapy there is, and if you can get a laugh in here or there, pretty good medicine too. You're doin' good!

I am so glad that your bathroom is being re-done, but I am not on board with most of the other posters. You should not have had to eat those costs. You hired a GC and he is supposed to be a professional. It is his responsibility to guide you through the building process. He is supposed to have the knowledge required to get a good end result. He hired the installer and it is his job to make sure that the job he is being paid to oversee is done correctly. You don't have to be a professional installer or a GC to know that you have to plan your tile layout before you put the first tile to the wall or floor. Why didn't he think that this was an important step? Can you find a tile installation video that doesn't tell you that the first step in the process is to figure out the best layout? If you were expected to know this and do it on your own why are you paying for his expertise? Why is it that so many people are okay with crappy work and excuse poor workmanship as though it is all we should expect? Looking above the door and seeing the weird little pieces tells anyone that they did zero planning and that is unacceptable. I am sorry that you had to pay for the tile to be correctly installed and eat the cost of your GCs failure. I have had similar experience, but am quick to explain that I expect to get the services that I paid for and if I don't I will make sure that my experience is shared on every social media site and with every waitress and cashier and gas station attendant, with every realtor and doctor and lawyer in town. A pissed off customer can cost your GC a lot more than the cost of re-doing your tile correctly and pushing back might just convince him not to cut corners and be lazy in the future. Laying down and accepting his failure as your problem is just supporting his poor work ethic.

So, I strongly suspect that the tub is not defective, but that the foam distorted the bottom of the tub enough to cause this problem. It's a known issue with expanding foam and will distort window and door frames, for example. I was reminded of this when I was installing my new front door and didn't have low-expanding "window and door" foam. Even though I was being careful not to overfill, I had to sawzall the foam out because it distorted the frame. You really want to avoid providing fixtures and such for this very reason. It gets really messy when something goes wrong with a customer provided fixture. Contractors want to work with things that they are familiar and with vendors with which they have a relationship. It's generally not the cost of the actual item but the labor of replacing it that's problematic. Regardless of it was the foam, or a bad tub, you are going to live with it. Nobody is willingly going to eat the cost of tub replacement - and you opened it up to finger pointing when you provided the tub.
