I plan on doing a full gut/rebuild on our bathroom this spring, and one of the things I plan on is his/hers shower heads. Problem is, one of these will need to be on the exterior wall of the house to accomplish this. Since I'm ripping the entire bathroom out, I planned on insulating all of the walls with kraft-face insulation for noise reduction, then putting the plumbing on top of it. Floor to ceiling tile will be installed on all the walls. The shower will be a tub with tile surround, not fiberglass.
Would insulation be sufficient to keep the pipes located on the exterior wall from freezing in winter? I'm located in the Midwest, Saint Louis specifically.

Lee I am pretty close to your area. Normally we would leave exterior wall in tact. Then we would running a series of 1xs and attach them perpendicular to the framing. Plumbing would would run inside of the 1xs. You might need to notch the framing but by 1/4" at most usually which is fine.
