Well... what I am looking for is something that I could drop in and durable material as well...There are so many options out there, without knowing your budget, we have no idea what "affordable" means.
What size are you looking at? Anywhere from 54" to 72" x 30" to 42" and even larger if you want a hot tub style jacuzzi tub.
Perhaps I should word things a little differently.Do not use a drop in tub with a shower head---they are not designed to have water around the tub/deck connection--
Why don't you tell us what you really want and perhaps one of us can help with that---
Opening the floor and relocating the drain may not be as big of a job as you imagine.
