Not going to go much into the bath stuff as I can't really comment without being there, but there are some red flags with the window. Untreated lumber shouldn't be used next to brick. The window looks racked, and so on, and so on.

I agree with JuneKnow.

Some situations can work with "canned solutions" - but many simply don't. Keep in mind that they make money by getting in- and getting out- quickly.

Older homes are particularly bad candidates for these solutions because of plaster instead of drywall, old plumbing and electrical, structural issues, out of plumb/level, etc. In addition, a "canned solution" often takes away from the architectural integrity and appeal of the older home.

So, yeah... the window has to come out. It's not square in the opening and the untreated 2x will rot. I know they intend to wrap it with metal / vinyl and caulk... but it's going to rot and you won't know it's happening.

If the plumbing is leaking it has to be fixed. They are either going to take the surround out - or cut through the closet to do it.

I'm not at all big fans of contractors who leave projects for the homeowner to do either (tape and mud the joint).

Here's how I would have addressed all of this:

1. A window in a shower is ALWAYS a bad idea. Always. In several situations I've removed the window entirely. This would require matching the brick on your exterior - but a decent mason could do that and would solve the tuckpointing issue around the window also.

2. I would come back with a standard tub, tile backer board and tile on the inside.

3. I'd install a fan for ventilation if there wasn't one - to make up for the missing window. The truth is that a window isn't an adequate substitute for a bath fan for removing moisture or odors.

Something looks wrong with the window on the left inside where the frame meets the sash. If they replace the wood on the exterior with treated lumber the aluminum coil should not come in direct contact. plaster patches should be flush , this could be done with thinner drywall and shims If needed often contracts will have disclaimers for wall patches and painting but if it was from a hamfisted Demo/install I’d see it otherwise. If the tub was a liner it may have to follow the existing tub but it should have been leveled. Plaster and lath can be removed cleanly if it is intact, sawzalls do not work well for this, an oscillating tool would. I would go over your contract first, then call the owner and listen to his solutions . Hopefully they are not paid yet.

Definitely some issue that need to be addressed.

As for the question, I'd prefer to know the concerns as soon as possible. No need to wait for them to get there, often times that can be perceived as an "ambush", and trigger a defensive response. If they know the issues prior to arrival, they will hopefully already be planning solutions by the time they arrive.

I'd like to thank everyone who responded with their comments and advice; I appreciate the feedback. Still waiting to hear back from the owner hopefully tomorrow they can address my issues.

A little more background. This is the only bathroom in the house so the appeal of having everything completed in a day was a big selling point for us. The old cast iron tub was replaced with a new tub (it was not a liner). There is no fan in the bathroom; hopefully that's a project for next year.

The good news is that the contractor has not been paid yet. I just determined that the overflow in the tub leaks into the basement.

"The good news is that the contractor has not been paid yet."

That is excellent news. Make it clear that he will not be until every issue is resolved to your satisfaction.

I thought the drywall installation was bad, but then I looked at the window and I haven't even seen a close up of the interior detailing.

What has happened to a sense of embarrassment? How can these guys allow these pics on the interwebby? I would die. Even drunken naked party pictures in your college days are forgivable in context, but this?

They should have used 1/4” Sheetrock if available. 3/8” works in a pinch, but requires more skilled work.

"What has happened to a sense of embarrassment? How can these guys allow these pics on the interwebby? I would die. Even drunken naked party pictures in your college days are forgivable in context, but this?"

Yeah, I would be really embarrassed by some of the photos of work done by "professionals".

And, evidently, I went to the wrong college.

I think that the idea to let the owner know you have some significant concerns before he gets there is a good idea. Approach it non-combative initially, but with clear expectations that it be resolved.

I can't tell you how many times I've redone a one bath house of my own and had to temp set the toilet just to have indoor plumbing - so I understand the appeal of done in a day.

Stuff goes wrong from time to time. All you can do is expect that the leadership steps up and makes it right. That seems to be the case here so that is a good outcome.

I would not Be happy about the tub being out of level . I think I would want different installers to fix this since I would have doubts about them being able to do it right. Seems like a solution is viable and hopefully it only takes them one more time to get it right.
