The booster bath is fantastic if you want something elevated and portable. My hubby got one for me for my birthday this past summer and it is the BEST present he has ever gotten me (yes, my life has certainly gone to the dogs). He also got the tropical shower for it, so I can hook it right up to my washer hookups and have hot and cold water. I can use it in the basement, or carry it outside to use. It is awesome. When my MIL saw it, she quickly bought one for herself as she bathes her Collie weekly and using the regular tub was getting old. I believe it accomdates dogs up to 175 pounds. Also, it has built in restraints to help keep the dog in the tub and you can walk the entire way around it, so you don't have to turn the dog around.
Can you tell I love it!?
