caution - it is my understanding that those require you to sit in them while they fill and empty.

Not sure if this is what you mean.

EXACTLY WHAT I MEAN...THANK YOU. THE ART OF PLACEMENT IN A SMALL SPACE AND IT WORKS.

Remember that those are *tubs* not tub/showers. To use it as a tub/shower requires the aftermarket installation of a tile flange, which can be problematic. They also needs to have the quickdrain option as a standard feature, or as an upgrade. Supplemental heating for the bath is also a good idea too, as even with a quickdrain, you do sit there all wet for longer than is really comfortable.

installing a hot water return with a set temp so it will be in my comfort zone quickly, and a warming drawer to heat bath towels thanks for the info and with all my questions answered , its a GO !!!!
