I make my soap in the kitchen too.
I measure my water for the lye on the counter next to the sink. I put the container with the water IN the sink. Then measure out the lye. When I pour the lye into the water I do it right in the sink. That way I don't worry about so much about spills or bad reactions. It can all go down the drain if need be. (I still use all the safety procautions though: gloves, safety glasses, long sleeves.)
Then when I've measured my oils and want to mix in the lye, I set the soaping pot in the other sink. So the farthest my lye water has to travel is about 12 inches.
That process works really well for me. Plus with my soaping pot in the sink I can see in it better when I'm mixing.
I too set aside about an hour or two of uninterrupted kitchen time. My husband learned early on that if I'm soaping that he needs to stay out of the kitchen. The only time he's allowed to come in is when I need him to help me pour the soap into the molds. :wink:
