Yep, like some of you girls say, the kitchen and laundry sink are great, too! DP, admittedly, was the one who used the baby bath in the lounge room (it was his thing to do with DS), and I used the kitchen, then the laundry when he was a bit bigger, till I started on the occasional bath with him. DP then used to wash him mainly, and in the shower - eventually I took over again as the main washer and he showers with me. When he could crawl we'd just let him play with the bottles on the shower floor, and because we use safe products that have the same toxicity as tap water, I don't have to worry if he accidentally swallows some.
If we hadn't had our baby bath lent to us, we wouldn't have bothered with one at all. We've kept a lot of things simple with DS and it's made him so damn portable!
