I am brand new to the plumbing world and have a couple of questions that I really need help with!!!
I am replacing the sink and vanity in my master bathroom, but there seems to be a small issue. The previous configuration had the sink drain into the floor instead of the wall.
1. All of the pics that I have seen online have the sink drain going into the wall (i this called a P trap?). In addition, all of the vanities that I have seen seem to be designed for the drain to go through the wall as well. Is my current configuration considered an S-Trap? If so, I have been doing some research and it seems like S-Traps do not meet plumbing code. Is this true?
2. My bathroom "floats" above my living room so there is huge I beam holding it up. This means that there is no room to run the drain pipe behind the wall because I would literally have to drill through the I beam. It seems like my only option to keep the configuration like it is now. Are there any other options?
3. I have attached a few picks. Pic 1 shows the floor drain. Pic 2 shows the I beam. Pic 3 shows the floating bathroom.
Thanks for your help!
