I have a fire pit and I am looking to do a cinder block wall that will be used as a seating area around the fire pit. Similar in style to this seating area:
The seating area will be 16" wide, 20" tall, by 6' wide.
Curved like in the picture above.
I live in Phx, AZ, so the area doesn't have a "frost" depth. I was looking to doing a 4" deep concrete base, using 4,000 psi concrete, with rebar.
#1 - Will this be a sufficient base for my block seating area?
#2 - How far should the seating area be in relation to the fire pit?
The pic shows it being finished off in stucco.
#3 - What other "finishing" techniques can be used on the block seating area besides stucco?
Here is a pic of my firepit (90% completed):
