OK, I think I have all my venting figured out for my basement bathroom, so now I am moving onto the supply lines. I have come up with a configuration that will allow me to feed the tub/shower, toilet and sink without crossing vents or supply lines.
Here is what I was planning:
Basically, I was going to run 3/4" supply lines everywhere, then stub out with 1/2". The main supply for that bathroom will run about 4 feet before it turns down the wall. In the picture the horizontal runs are about 5 or 6 feet.
From a book I have, it tells me the toilet stubout should be 8" above the floor, and the sink stubouts 19". Should I add an inch to these numbers to account for a finished floor?
Is 3/4" everywhere overkill? Should I supply the toilet and sink with 1/2"?
On a final note, my drain for the sing is about 17" above the floor, is that ok?
Any help would be appreciated.
Also, I assume it does not matter that my supply lines for the sink are to the right of the drain? I know it seems standard that the supplies usually surround the drain...

with hot supply pipes,the bigger the diameter, the more wasted time and water when you first turnit on in the morning, after the hot water in the pipe cools, your faucet will not deliver hot water until the pipe full of cooled off water is replaced, so you pay for each increase in diameter.
this of course doesn't apply to cold.
