I posted a few days ago asking about a Sundance Spa. (Marin Model) I was hoping for some responses or comments. I am about to buy a Hot tub and want to be sure I am choosing a correct brand. All dealers tell you they are the best and I about got convinced to buy a Gulf Coast spa, which I learned here would have been a mistake. Since I think Sundance is a good manufacture (correct me if I am wrong) my question is this: Is the Marin too shallow? It is 33" deep compared to 37.5" with regular sized sundance models, although it is not the two man which is 30.5". I want to be certain my shoulders get the benefit as well. Neither my Wife or I reach 6 feet tall. The reason for then Marin model is the layout fits my location better. Please help. Thanks.
