Hey Lasercomp,
The shallow end is 10' x 14'. I suppose that would be crowded with more people in there, however, we haven't really used the pool that way. Most of the time. so far, the kids are jumping and diving in. Any times we have been to my brother's pool, very little time was spent in the shallows.
I use the deep end for SCUBA diving practice - very strange I guess but it is cool to do buddy drills and fin techniques and have lots of room. I'll post some pics of that later on.
At this point the pool is still in its infancy so we have not had a large group over. - Majority of the Kids in the area are 8 to 18 years old.
My other future purchase may be for a couple floating chairs if anyone has a good model/style suggestion?
