I think you’re looking for a heated soaking tub. Not too difficult to come by using the power of Google.

c9pilot...Thanks for your comment. yes, I have been googling about them. I was hoping someone who has one would tell me their experience with having & using one. What the pros & cons of having one in their home.

I had a roman bath, if that counts. We ripped it out. And I think that about sums up how I felt about it.

Look at the Kohler Underscore with heated bubble massage. It comes in many sizes and has excellent reviews if you search in these forums. I sat in one in the showroom and the lumbar is fantastic.

My bathtub consultant said she got to try the bubble massage at a hotel in Miami and said it was awesome. Much quieter than standard air jets, and they have a newer purge/clean function that keeps it from getting mold or gunk to scrub out (like the older jacuzzi tubs).

I would buy one of these in an instant if they had a side drain which is required for our build. So we’re having to go with an unknown MTI tub.

Thanks c9pilot, I like that deep tub option with heated, bubble massage. That's a valid option to consider. Appreciate the info!
