If you have the space for a nice soaking tub,?a?whirlpool and/or air function?can be?a good idea, if for no other?reason than resale value. These features are not that much more expensive but they do require a separate electric circuit, which may be a deciding factor. Usually I would suggest a 66″ or a 72″ long tub as a 60″ is rather short, but it may come down to space and there are many shapes available to choose from.?A rectangular, oval shape or a corner tub work well and are usually done in a deck of some sort, using?a?drop-in or an under mount installation. Normally?I would not suggest using?a step.
I will certainly give you input on the?type, shape?and?location for a tub?when we discuss the ideas you have in mind.
