Has anyone installed a plunge pool in portland oregon? or even not in portland oregon. we just bought a new house and want to install a small plunge pool when we landscape. I was looking at prefabricated concrete pools, but I dont know that it is the most inexpensive option after delivery and having to hire excavators, electricians, plumbers anyway and then someone to crane it in. anyone have experience with this? or having a plunge pool poured on site. any advice is ap preciated
