What to do with this zone?

We have a smaller house ~1200 sq. ft. Single story ranch with a boiler and baseboard HW heat. Zone 1 is all of the house except for the bathroom which is located in the middle of the house between the kitchen and master bedroom. There are two baseboard radiators in the bathroom. One is underneath the bathtub :eek: (~3' and I have no idea why it was placed there) and then goes back into the basement and up to the other that runs along side of the wall for another 8 ft. I don't know why the the bathroom was split off to its own zone and by looking at the piping in the basement it looks like the house was originally all on a single zone. We just purchased the house last year. There's no reason for this bathroom to be on it's own zone and the thermostat in there has been shut off since it stays within a degree or so of the rest of the house (I turned it off because someone cranked it up to like 80 one night and the boiler was running way more than usual until I discovered why). I'm not sure what to do with this zone. If I leave it off is there any issue with water not circulating through it? Can I wire it so the circulating pump for this zone runs when zone 1 does and if I can do that is it even worth it to do? Here are the specs: Utica boiler model POB 3 (probably original to the house - built in 67) Taco SR 502 2 zone switching relay Taco 007-F5-7IFC cartridge circutor (one for each zone)
