I'm not familliar with that tub, but you asked about the foot dome.
Wet test, of course and decide for youself, of course.
However, if you do not get a tub with a lounger, I'd pay attention to how the tub gets the feet and calfs. My tub has a dome and I can float my legs out over the dome to get an ok massage, as well as get the soles of my feet, and ankles. Since the dome is in the middle, you can use the dome from any postion in the tub. So for me, it was a plus.
Wet test both styles and see for youself what you prefer.
