Purchased a venco Harmony 3 tub. It all seemed fine for the first six months then we noticed water in the basement so we called our plumber, he traced the water back to a crack in our tub. Venco offered to pay half. Tub was fixed, a month or so later we had more water in the basement our starting point was to look at the tub - again a crack, at the other end of the tub. I have since found another so in total three cracks that led to water in the basement. We have had duct tape in our tub for most of its installed life.
Buy a tub from a different manufacturer as once a tub is in it's hard to change.
