A very affordable, yet classy model. This fiberglass liner is designed specifically for an internal heater, but the walls are conical as in all wellness models, therefore it is very comfortable and of course easy to maintain. One can choose either fiberglass or wooden lid. If you want a more luxurious look, the round wooden edge will definitely make a difference, just look at the pictures. It is not only good looking, but practical too. The internal heater will heat the water faster, whereas wall and bottom insulation that is already included, will save you time and money when using the tub.
