You know when it's cold outside and you take a shower and the first 10 seconds of water is freezing cold? Does the area in between the sheetrock really get that cold when the house is 70 degrees?

If your pipes are deep enough, i think most ground temps are 52F.

You are in Houston.

Don't be surprised if your house has no insulation. Really.

If the house has a crawl space, then water plumbing is in the cold, If not insulated well they will get pretty cold if no hot water is flowing through them for a long time.

Takes my shower about 3 minutes to warm up. There's a lot of piping from the HWH in basement up to the shower.

I'm crazy like you.

If your water comes from a surface source vs a well source, it is pretty cold to stary with when the weather is cold outside.

How cold does it get in Houston? Where does your water come from? Important questions to your question.

My old house was two sheets of sheetrock, and about 3" of airgap...the water could be freezing cold (or frozen) or scalding depending on what was going on.

Funny, only woke up this morning recollecting a thermodynamics assignment where we had to work out heat transfer difference between lagged and unlagged pipes...1/4" (yes not your size), and typically lagging actually increases heat transfer with run of the mill pipe insulation.

I'm just talking about the pipes in between the water heater and shower. So 18ft or So?

Well that water that isn't moving will at some point get down to ambient temperature. Since most of us run around 98.6 degrees F, 70 would seem pretty cold.
