Planning on moving up in size from our current 12' x 30" summer escapes (EZ-set type) pool to an 18' diameter Intex Ultra in the coming weeks. I feel my youngest child would not be able to touch the bottom of a 52" pool and keep his head above water, so I'm looking at the slightly shallower 48" model, which seems to perhaps be an older model? It seems the 48" depth Intex Ultra is harder to come by, and that 52" is now the standard.
If the 48" is indeed an 'older' design, what difference would there be in construction/quality vs. the seemingly newer (or at least more common) 52" depth model?
