My wife and I built a sunroom this year and kind of waffled on whether to put heat in or use it as a 3 season room. We kind of compromised and ended up installing one of the ductless air conditioner/heat pump units. Living in New Hampshire the heat pump unit isn't very effective at temperatures below 20 degrees F, which we knew at the outset. However, and this is my question, if we have the walls plastered, can plaster stand up to the wide swings in temperature without cracking? Without the cooling/heating unit turned on, the temperature extremes could go from -10 F in the winter to +100F in the summer.

I am going to replace the linoleum floor in both my bathrooms with ceramic tile. One toilet sits on wood, the other on concrete slab. My question is, should I remove the toilets, and tile under them, or tile around them? If I tile under them, how do I deal with the added height... do I need to change the flange height? Is that an easy thing to do...? Thanks! -Jim
