I do 5 gallon BIAB batches in an 11 gallon kettle and 10 gallon batches in a 15.5 gallon keggle.

An average 5 gallon batch requires about 6.8-7.0 gallons of total water volume. During the mash with the grains in the 6.8-7.0 gallons of water, the grains displace up to a little under the 9 gallon level of the kettle, so you're good with a 10.0 gallon pot.
Primary #1 - Midnight Ryeder (Midnight Wheat and Rye)
Primary #2 - Florida Weiss
Primary #3 - Kane-DOH APA (Honey Citra APA)
Secondary #1 - Downtown Flanders Brown (brewed August 2012)
Keg #1 - Raspberry Florida Weiss
Keg #2 - Cinnamon Raisin Cider
Keg #3 - NONE!
Bottled - NONE!

Did my first BIAB brew day yesterday. It went great no problems at all. Conventional BIAB procedure with my 15 gallon keg boil pot. My mash efficiency was 85% and I only lost 1 gallon of water to grain absorption.

I just completed my first two BIAB's (sorta). I didn't want to brew in a paint strainer since no one knows what you are drinking after heating up nylon to 168 degrees (for mash out) so I took my 5 gallon pot and drilled a 1000 holes on the sides and bottom. I then lined the inside with stainless steel mesh (80 threads per inch). I added the grain to that pot and then dropped it in my 9 gallon pot with the heated water. I had a clean beer with no more in the wort than with my all-grain system.

Both were Rogue Hazelnut Brown clone. My efficiency was 72% and then 84% with NO SPARGE.

Better yet was how little time the entire process took. It took me about 5 hours for everything (including cleanup).
