Cutting the pex to add the lines for the towel warmer:

These two copper stubs come off the radiant floor pex we ran way back when, and will run hot water thru our towel warmer:

Peeking at the by-pass valve for the towel warmer, thru the access panel. This will allow use of the radiant floor, independent of the towel warmer:

And of course the copper, pre-installation:

A bit of extra work, but little luxuries like this are much more affordable when we do the work ourselves. I’m looking forward to warm towels this winter 🙂
