Maybe you could find some old Xantec RAT1's and an old receiver in your junk box.
Old receiver -- check.
I'm not familiar with the RAT1 unit. Is it IR volume control?
If so, that wouldn't be needed as the areas discussed would be set-and and forget it. Being powder room, hall, etc. there won't be any UIs. No keypads, volume controls, etc.
