I have to replace the plumbing in our second floor bathroom. I have noticed the old pipes run through the floor and then under the tub with the traditional risers. I am planning to run new pipes in there and I am thinking it might be better to plumb the bathtub by running the new pipes through the bathroom ceiling and then down to the tub. Does this approach make any sense? Will it cause problems? I am new at this and would appreciate any responses. Thank you!
running the water pipes in the ceiling (no third floor above)in a cold climate could freeze, even with insulation on top.unless you are changing the layout, and if there is no problem with the plumbing in regards to it working, just duplicate what is there. but always check the structural elements ,that no past plumbers have hacked up the support joists.easily fixed by making a three quarter inch plywood sandwich (glued and screwed)on both sides and then redrilling the hole through the plywood.
Thanks for your response. Actually, the house does have a third floor so there seems not much worry of pipes freezing.
