rough in

I'm about to install all of the rough-in plumbing for the above-slab drain and vent system for the first time and would like a "pre-inspection" by knowledgable pros. Don't assume I know something that's not shown or said, since I'm strictly DIY. Absolutely tell me about any code violations...

I’m adding a full bathroom in my basement. The plumbing was roughed in, and a toilet was already added by the previous owner. I just want confirmation on what I need to do to complete the shower drain/vent plumbing. I believe all I need to do is add a P trap to the 2” drain line in the...

Hi all, I have a plumber, as I definitely am not. But this does not seem easy. The rough in, not counting the baseboard, is about 11.25" The floor has radiant in-floor heating, so concrete floor. This part of the house (new concrete foundation, in-floor radiant, etc.) was remodeled about 20...

Hi all, I'm installing a new utility sink and relocating the washer. Working off of Terry's infamous Laundry Tray and Washer Rough-In diagram, I placed the washer and sink on separate walls. So my question: 1. Is it okay to turn the 2x2x2 long sani-T 90 degrees so it's horizontal rather than...

I recently bought a house that was built in 1994. It is 2 stories with a 75% finished basement. In the basement, there appears to be a rough-in for half bath, which I plan to finish. There is a toilet rough-in (3 inch PVC) which looks good, with 12.5 inch from back wall, 15.5 inches from side...

I'm planning on doing the rough in plumbing for my small bathroom in my garage. Is this the right way to run the drain (black) & vent (blue) pipes. Do I need the vent pipe between the shower and toilet? If I put an additional floor drain after the sink, do I need another vent pipe in between...

Hi plumbers and DIYers, I'm looking for some feedback on my proposed rough in layout for a basement bathroom that I'd like to put in. I live in Portland Oregon, and I plan to have an inspector review this layout after I'm done, but it would be great to get some early notes before I go breaking...

I'm installing a new bathroom in basement with a lift station. The top of the inlet on the station is about nine inches below the top of the basin. I'm running a drain from the toilet over to it from about ten feet away. So, I have to plumb the toilet that allows it to be correctly vented and...

I am planning on putting in a 60" double sink vanity. I have removed the drywall and this is what I am looking at. I have called several plumbers but they are too busy to do the work and I am unable to find another available plumber. I figured I would do it myself, until I opened the wall and...

im installing a bunch of wall mounted lav faucets which I have never done before. Just wondering where and how the shut offs are usually plumbed. My thinking is that you just come out of wall, have an in-line ball valve, then go back into wall and tie into the rough in. Is this how it’s done...

I currently have a rear discharge Gerber Maxwell with a rough in spec of 4 1/4 “. Can I swap in an American Standard Yorkville that has a rough in spec of 4” ? Or do I have to find replacement toilet with 4 1/4” to match the Gerber ? How important is the 1/4 inch difference in terms of...

Hi, I’m new here so I hope my first post makes sense! I’m remodeling my cottage bathroom. There is a floor joist right under and parallel to the wall where the shower, toilet and sink are. So the drains and vents cannot go trough the bottom plate of the wall like they usually do :( To solve that...

Thanks for all the great advice over the years!

Hi all, I've been hoping to replace all the dated, tarnished, chipping etc trim/fixtures in my bathroom with new fixtures in a soft brass/brushed matte gold color. I wanted to start with the shower trim, since the bonnet covering the handle is cracked & it looks pretty bad. I unscrewed the...

Hello, I know variations of the question get asked a lot, but here is my personal situation. I recently moved into a new (used) house with a basement bathroom where the toilet has a 15.5 inch rough-in (house built in 2012), which has almost a 5 inch gap between the tank and the wall. Because...

I am trying to frame in my walls for a bathroom that was supposed to have all the rough in plumbing complete. As you can see in the picture, it looks like it was all setup, but when I took the cover off of my box out labeled,"Tub Drain" so I could estimate where to put the back wall, it looks...

I finished roughing in my bathroom yesterday and pressure tested successfully. Today I was cleaning up and getting ready to install Kerdi board and noticed that I installed my Grohflex universal roughin box upside down... cold line is plumbed to the hot side, etc. I'm glad I found this out now...

Hello everyone. I want to install two toilets (Toto Entrada) that has a rough in size of 12". However, one of my toilets has a rough in of 11.25" and the other 11.5". I notice from the tech specs that there is only 3/4" of extra room in the back of the tank. Is this too close for comfort...

Hi there, I'm new to this thread and a first time home buyer. We're redoing our bathroom and found that our rough-in will be about 11.0" - 11.25" from our finished wall (we'll have tile on the wall). Our contractor is telling us that we'd need to find a 10" toilet or a 12" toilet that will fit...

Good Morning, I need to move a rough in shower pan stub about 5-6" after a remodel. Is there anything wrong with setting up an offset with two 45s and straight piece right before the in ground P-Trap as shown in the image below? The P Trap sits about 20" below the surface. Thank You!
