How to choose a baby bath tub?

I bought the Fisher Price Sling n Seat tub and have never regretted my purchase. I really like how it lets me bathe my baby hands-free instead of the traditional method where the baby has to be supported with one arm at all times. It's not easy bathing a wriggling baby with one hand, plus it's not fun for the baby either. This bath tub has 4 different stages to adapt to the baby's growth stage. If price is a factor for you, then you can get a standard bath tub, but do get a bath sling to make your life easier! :)
