this is not a quality tub. It arrived damaged and missing parts. There are some basic issues that the company is aware of and could be easily improved but they have decided not to bother. The door to access the equipment and drain has 4 screws that are difficult at best and some arrived stripped. A simple addition of an extra plumbing piece would allow the drain to be accessed without removing the door.  Also the power pack is mounted to the inside of the door making removal and reattachment even more difficult. while the cost is reasonable, it is not near as comfortable to the body as an acrylic spa. one positive is customer support seems solid.
