That was kind of the original plan as it is the way to do it properly(properly being fibreglass everything and not use a liner) but no I won't be doing the whole bottom. I will be concreting the recess where the pipes are at the moment and fill the hole they are going through with concrete. The gap between hole one and two will be fully concreted at the top even the the collar doesn't show that it will, yet.zennzzo;2172693; said:Looking good...are you going to do the entire bottom with concrete?
