Water line insulation

[stan heller]

I am installing a bathroom in our sunroom additionwhich will be insulated and only heated by a fire place when in use. My problem is that I am running water lines to the sunroom from the basement of the house under a sub-floor in the garage into the sunroom and I dont know how to insulate the pipe. I dont want to use any electrical freeze protection because the pipes will be unaccessible after the floor is finished. Would the standard foam pipe insulation be enough? What can I use to assure the pipes wont freez?

To assure that the pipes will not freeze, you would need to either heat-tape the pipes or have a back-up heat source to the room, maybe just opening a door from your home to the sun room Safer would be to add either a baseboard electric heater or a gas space heater I have repaired many insulated pipes in unheated areas when the temperature drops below freezing.
