It sounds like it’s easy enough to do, but am I missing anything that could go wrong or cause any other issues??

How does he intend to waterproof the newly built up floor and integrate it with the rest of the waterproofing? You can't just spot waterproof a shower.

@User I'm not sure the specific plan to integrate the new to the old. He acted like it wasn't that big of a deal? So I need to ask him the specific steps on that. I originally though he'd have to remove one row of wall tile in order to tie in everything, but he said it would be fine to leave just 2" on the perimeter. He used TEC hyrdraflex for the waterproofing. Here are a couple pics during construction. First pic is one coat on walls and fresh mud bed and second pic is second coat on walls and bed.

@cpartist That's what I was wondering as well and why I am asking if this sounds right. He acted like it could be done. I would think the areas would have to at least be overlapped to be waterproofed. And that can't be done with a row of tiles on perimeter.

@User Unfortunately I am aware of some of these issues and brought them up along the way. Our good friend is the owner of the company. I trust him. He and his installer have been doing it this way for years without any issues. Fortunately, he gave us a great deal on the project. It is a running joke that he will repair it when/if it leaks.

What would your solution be for the incorrect slope?

"He and his installer have been doing it this way for years without any issues"

Does not mean it is correct, and there very well may be rot issues behind the mess that has not shown up yet.

"What would your solution be for the incorrect slope?"

Rip it out and do the pan properly with a flood test before tile is installed. As well as properly tieing in the membrane flashing up the wall behind the tile.

^^^ And find someone to do it correctly. Not just the way they've been doing it for years.

@Joseph Corlett, LLC Thanks for sharing. I did not realize tiling over the existing was an option. Not sure we will go this route or not, but good to know in case we do.

I am quite aware that improper waterproofing is no joke. This was a battle with my husband and flooring contractor (our good friend with over 40 years in the industry). I shared all of the horror stories I've seen on here with them both. This method is how he has done it for many years and the methods he used in his own home and many high-end hotel bathrooms. I know he wouldn't do something in our home if he thought it would fail. The actual installer couldn't explain the slope issue and was completely embarrassed...especially since I asked him about it needing to be 1/4" per foot.

In the end I agreed with my husband that if he does the work "his" way and it fails, it is on him. If we try to tell him the "correct" way and it fails, it will be because he did it our way and would be on us. I will just probably continue squeegeeing the floor for now. There is an access panel in our closet on the wall where the valve is so I plan on peeking in there on a regular basis to sniff out any water.

In the end I agreed with my husband that if he does the work "his" way and it fails, it is on him.

The only issue is that if it does fail, (and I certainly hope it doesn't!), then it could cost you even more than just redoing the shower.

@cpartist Thanks! I hope it doesn't too!! I've been worried about it failing since day 1, even though I trust our friend 100%. Luckily I have a super sensitive nose and can sniff out water damage. I'm hoping since the shower is stupid big and that we have a rain showerhead, the walls won't see a ton of water (except for cleaning which I will be super careful about). It does suck that it is on the second floor. And honestly, I'd be just as worried about leaks even if they followed the TCNA guidelines. Right below is our kitchen, which we are remodeling in a few months. We own a commercial construction company and employ carpenters and painters, so we have the resources to quickly remediate any issues that may come up compared to most homeowners.

comical this thread

What's so funny, Mint?

@Mint tile Minneapolis Glad you're entertained...but what is the point of your comment?

I think he's implying there's a lot of bad advice being given out in this thread. :( I would listen to the pros who do this for a living.

cpartist:

You are probably right, however, I'd like him to be specific as to what advice is bad and why. Maybe I'll be entertained too.

JC ,,,,how you feel you're owed or due a detailed time consuming response baffles me.

Gen pop.,,,

Almost as much as the reasoning in ones mind to spend they're days advising folks on the web of a skilled trades technical aspects in which they arent trained nor skilled.

OP,,, you currently are your own worst enemy if im reading your own response to your drama correctly. You made a poor choice in TRUST and seem bent on continuing down that path and no one can help you there.

There are dedicated tile tradesman and women out there.

HIRE one. HIRE ONCE.

lastly yes the advice is horrible here on this thread near comical.
