I'll see what I can do. Offhand, I don't know how well the tub holds water (recently moved in and all). My main freezer space for bottles would end up being outside, and the weather hasn't been all that cooperative on the freezing front lately.
I'm planning to cool the wort in the tub with some ice around the outside and pitch the yeast when the thermometer reads 70F. Sound kosher?
Am I going to have to get a second refrigerator if I want to make beer in the summer?
The cooling process you have will work. That's what I did for my first few batches. I found it helps if you swirl the kettle or stir the wort with a sanitized spoon while the kettle is in the water bath occasionally as the ice bath will quickly cool the wort on the edges, but not in the middle.
If you find the water bath/frozen water bottle method is working for you, and your HVAC system keeps your house the same all year, you'll be fine without the extra fridge. I like the extra fridge because I'm too lazy to deal with the water bath and constantly freezing water bottles. I just set the temp controller to the fermentation temp I want and walk away.
