Is one cold corner of the house going to be a problem this winter?

I had nearly the same setup in my old house, bathroom and laundry stuck in a corner with no radiators anywhere near them. It was fine until the first real cold snap, then the bathroom never got above about 55 and the toilet tank sweated constantly. What saved me was a small…

Just bought our first place and the heat layout has me scratching my head. There's baseboard heat along most of the outside walls, but the whole corner where the kitchen and the little bathroom sit has zero heat at all. Not a radiator, not a vent, nothing. The inspector waved it off when we bought the place, said those rooms pick up warmth from the rest of the floor, and honestly we didn't think much of it untill the temps started dropping.



Now I'm second guessing that. The kitchen sink sits right under the window on the outer wall, and both doorways into the kitchen are wide open to the dining room and living room, no doors to hold any warmth in. The first floor is only around 800 sq ft, so in theory the heat from the living room should drift over there, right? The bathroom worries me more than the kitchen though. Pipes in an unheated corner in February sounds like a bad combo. Has anyone lived with a setup like this? Do you just add a small electric heater in those rooms and call it done, or is this something worth fixing properly before a pipe gives me a really bad morning?


I had nearly the same setup in my old house, bathroom and laundry stuck in a corner with no radiators anywhere near them. It was fine until the first real cold snap, then the bathroom never got above about 55 and the toilet tank sweated constantly. What saved me was a small electric wall heater on the bathroom wall, wired to its own thermostat. Cost me an afternoon and it kept that room usable all winter. A cheap plug-in space heater works too but only if you're disciplined about never running it unattended, which in a bathroom is a real ask.

Check where those plumbing runs actually go before you spend anything. In my place the kitchen sink lines ran up through the outside wall, and once I opened the cabinet and got some foam sleeve on the pipes plus sealed the gaps where they came through, the worry dropped a lot. Warm air from the rest of the house drifting in does more than you'd think when the wall itself isn't leaking cold. Also worth leaving that sink cabinet door cracked open on the coldest nights, lets room air circulate around the pipes. If it still sits cold, extending the baseboard loop into that corner is usually not a huge job depending on where your supply line is.

I'm just joining this thread, and I'm pretty panicked about the whole unheated space thing. My issue is a bit diferent though; I have a small utility closet near the back door that basicly just sits outside the main insulated envelope of the house, and I'm worried about what that means for the exterior walls. I keep reading about insulation being key, but I don't even know where to start looking. I feel like the heat just completley bypasses those spots, even if they're small. Does having a draft in a closet like that make the rest of the house feel colder faster?

Worth checking wheather the baseboard loop actually runs past that corner before assuming you need electric heat. In my last place the kitchen had no baseboard either, but when I pulled the trim in the dining room the pipe was right there under the floor. Adding a few feet of fin tube along that outside wall was a weekend job for the plumber and the room finally stayed warm on its own. If your system's forced air instead, a vent extension might be just as easy. Either way, if the loop's nearby, a proper fix might be cheaper than you're fearing.

Agree with the wall heater idea, that's basically what ended up working for us. One thing I'd add after living with it: think about what happens when the power goes out. Our electric heater was useless during a two day outage one January, and that unheated corner got cold fast. After that I got in the habit of opening the cabinet under the sink and letting the faucet run at a trickle whenever the forecast looked ugly. Cheap insurance while you figure out the permanent fix.
