Intoduction - What sort of Pool is better to be considered for a long run.

Hi,

I'm Kristin. I with my husband Matthews moved in to town few months back. We presently own a 0.193 acre plot which holds 4 Bedroom house. We build a small veggie garden in our yard and are planning on having a small circular pool of 4 ft radius and 4 ft depth.
Usage of type would be more feasible when considering to cost and comfort? We plan on having it maintained regularly so are for the long run in town, so with future prospects of indulging a time with our kids etc in the future. Now we are just us two.
