'Cause it IS the Most Important Room to Keep Warm

We have a three level home. Most of my day is spent on the middle level which consists of the foyer, the living room, the dining room, the kitchen, the den and the guest bathroom [it is a half bath]. I have to avoid the stairs due to the condition of my legs - so I am basically stuck on this floor from the morning until bedtime. No big deal - I have everything I need - I am happy.

Well, I was happy until the temperature dipped down into the single digits/negatives. Although this floor stays relatively warm we have had one small problem.

The bathroom. The lil' bath [sink & toilet - with nary room to turn around in] is off our miniscule foyer within feet of our front door. This proved to be a challenge in using the facilities as the bathroom has no heat vent and with the cold air from the front door - it was COLD in there. Painful, don't want to remove any clothing and NO I surely don't want to touch any porcelain right now 'cause, seriously? I don't need anything to freeze kind of COLD. Outhouse COLD tadpoles. It was cold.

I know, I know...I could use the bathrooms upstairs [they are oh, so toasty] but I simply can't go up and down 18 stairs that often during the day. [Oh, and before anyone asks - we got the house before I had this problem, otherwise we would be in a one floor home! ]

Here is a picture of our "foyer" and the front door. I took this picture from the bathroom door way to give you an idea of how close the two are to eachother.

Well, my youngest took pity on me. Either that or she was becoming tired of hearing me yelp everytime I walked into the littlest igloo. She graciously went into the garage and carried up our space heater to install in the bathroom. It is an awesome [and safe] heater but it barely fit.
This was taken with my back to the wall - this is a really small space. Baby - oh baby - this thing works like a charm. It is now the warmest room in the house.

But my daughter noticed one flaw with her heater plan. She rectified it immediately:

And then she made me cake!

I have good kids don't I? I know I do. This is a practice cake for our Super Bowl Party in February. I think it looks awesome.

By the way - if this post was a little TMI - please leave me a comment. I don't want to offend anyone :D And by all means - please feel free to laugh at my bathroom misfortune. Because I know you will. heehee!
