We have the Nuby baby bath and sat that on the floor of the shower. We do have a bath but he is 2 now and loves a shower also!
My first born had all his baby baths in the sink 🥰 when he got bigger we had a baby tub in the shower and then when he was a toddler he’d just shower. We now have a bath which his younger brother prefers but our three year old still prefers showers :)
For a newborn I'd say a baby bath is the easiest option anyway. Once they're a bit bigger some people just take LO in the shower with them and there are also toddler baths you can buy (basically just a bigger version of a baby bath). When we were temporarily in that situation I bought a fold up paddling pool (I think it might have actually been marketed for pets 🙈) and stuck that in the shower to bathe toddler
If your wanting a changing table a lot have them included, I'll attach a picture of the one I've got which is a good height for changing baby as well as having a removable bath
