Welcome to our forum.
tanstaafl2,Congrats & good luck with your new tub. Wife and I wet tested tubs with foot domes and we felt they made maneuvering difficult and maybe dangerous. Fortunately the 385 solves the problem as Duff pointed out. Please be careful with the foot dome.
time will tell if it proves a problem!
I hope to read about your opinions after it's delivered and you have had time break it in. By the way... I'm sure many of us would be interested in knowing what it cost and what region you live in since there are higher surcharges in many areas.
