Reply to comment by SteeleRain01 in Replacing tub drain plumbing, filling the hole that it's in and, finally, connecting the tub. by Deh_Strizzz
Oof, definitely not the news I wanted to hear. Are these really my only options? Can I not install the flat p-trap that's pictured and remove the other p-trap?

Could you? Probably. Ultimately as long as the drain opening in the tub is higher than the outlet pipe for that flat p-trap, it will "work". I would have concern about the volume water going through that flat part and future clogs. It is still going to have to connect over to that pipe coming out of the floor, so I'm not sure how that would look. What is the tub brand and model number? Is it an alcove tub or free standing?

Sorry to tell you, but if you use that tub you are absolutely going to have to break up that concrete floor. The entire round base sits on the floor, so there will be no way for the outlet pipe to exit out the side, it will have to drain into a pipe directly below. This is also what your (terrible!) installation instructions tell you to do. The part about using the flexihose in the instructions only might work if the existing drain is still under the opening in the bottom of your tub. From your pictures, it doesn't look like it will be. Breaking up the concrete is not that terrible. Buy or rent a heavy-duty rotary/jack hammer and you can do it yourself. Then, once your new pipe is run, you can fill and patch the concrete floor that is not directly under the tub, and tile as normal. This YouTube video does a fairly good job of showing many of the steps you need to take. https://www.youtube.com/watch?v=rjgurg4Mcnc

Actually, the inside bottom of the tub will end up hanging over the current hole in the ground (about halfway over) which is why I figured I could snake a pipe from the center drain over to the p-trap

In that case maybe it will work, but I'd still be worried about the shallow or lack of drop from the top of the drain in the tub to the horizontal drain pipe. I do hope it works out for you. Good luck.

Thanks haha. I'm most likely going to bring in a professional at the very least just for a consultation. I truly appreciate the help you've offered on this.

Of course! A consultation is always a good idea and worth any money you might pay now to avoid a costly repair down the road. I may also be too cautious because all my tubs are always on second stories or wooden floors and would cause catastrophic damage if something went wrong.

I'm not sure why I was so afraid to just break into the concrete. I thought it'd be harder and much more technical than what it actually ended up being. Rented a demo hammer and I was done in about thirty minutes. Best of all, I now have the peace of mind from not using any flex pipe (which is actually what the plumber recommended I install). Thanks for the rec on this one.

Oh that's great to hear. I'm glad it worked out. 👍
