My Current portable hot tub can not be used in winter and I have to store inside after summer... Can This be used throughout all the seasons Like a regular hot TuB, or are there temperature Specifications on this?

Yes, these are insulated hot tubs with insulated covers, so they can be used outside in winter areas. We have even shipped these into Alberta, Canada. As a helpful hint, you may want to set it on an insulation board to prevent heat loss through the floor area. That will help keep the heat in the water.
