Background: I live in lower southampton twp , PA, and I'm redoing my small powder room (54" wide by 48" deep) in our new home. Once the walls are finished with tile, the distance between the walls in front of and in back of the toilet will be approximately 47 1/2 inches (I subtracted 1/4" tile, multiplied by 2 = 1/2"), and the distance between the walls from side to side will be 53 1/2". I bought the following fixtures: a Toto Ultramax II which is 28 5/16 deep and 16 1/2" wide. I also bought a Ronbow Cami cabinet and sink, which is 18" wide and 16 1/2" deep. The toilet is to the left of the sink as you face it. The toilet is close to the left wall and the cabinet will be close to the right wall. The toilet flange has a 12" rough-in. The center of the flange (if left as is) is currently 15" from the unfinished wall (to the left) but will be 14 3/4" from the finished wall to the left. Also, there is baseboard heat which is about 9 1/2" high off the unfinished floor. It runs the length of the wall to the left of the toilet, which I did not include when I measured 14 3/4" from center of flange to the left hand wall. I believe the baseboard heat extends less than 3" from the wall. The left edge of the cabinet/sink will set 34 1/4" from the left wall (when finished), extend 18" to the right, and end up about 2 1/4" from the right wall (whew!).
My questions are as follows:
1. I was informed that the "2003 International Plumbing Code calls for a minimum of 15" clearance from the center of the water closet (toilet) to the nearest side wall or other fixture and 21" clearance from the front of the bowl to the closest wall or fixture". Does this mean that I can not have this Ultrmax II installed in this powder room since (by my estimates), I will only have about 19 1/4" in front of the toilet to the finished wall?
2. Is the above rule a mandatory code?
3. With reference to the "15 inch minimum clearance from the center of the flange to the nearest side wall or other fixture" rule: Do I measure from the edge of the baseboard heat cover (which is about 3" wide) to the center of the flange to derive at 15" ? (so that 15" now becomes 18" from the finished wall) or do I measure from the edge of the finished wall to the center of the flange? What do you recommend?
4. My installer will move the flange for me as part of the installation. We already discussed this. How far to the left should it be moved, in your opinion? My gut tells me that the flange should be moved to the right so that the center of the flange is 15" from the finished wall. Please advise.
5. Should I consider moving the toilet farther away from the left wall to accommodate the baseboard heat? If I do this, the center of the flange will be 18" from the left wall, and I will still have about 16 1/4" from the center of the flange to the edge of the sink on the right hand side (thus, satisfying the 15" rule on both sides of the "center of flange". However, will this cause a problem with the supply line being 3" farther away from the toilet?
6. Also, I am thinking that the flange should be moved back a bit, that is, toward the back wall, since (I believe) the center of the flange measures about 13" from the unfinished wall behind the toilet, but I do not have an exact measurement at this point (I will measure that tomorrow). This may maximize the area in front of the toilet bowl once the installation is complete. Therefore, my next question is, how much space should there be behind the toilet to the finished wall ? (one inch? one half inch?) What would you recommend?
Thank you in advance for all of your assistance in this matter.
