My kids are 2yrs apart. Before we moved it was really easy as we had a great bath that was easy to have Charlie playing up one end and me holding Ollie down the other end. When it was time to get them out I'd pull Olls out first and wrap him in towel and lay / sit him on the floor on a sheepskin or extra towels. Then pull Charlie out and wrap him in towel, then he'd walk out to the lounge room and I'd carry Ollie and I'd dress them out there.
Our current house, and we moved here when Olls was 6months old, has a massive corner spa and it was a farkin nightmare to bathe him in, I had to be in there with him. Lucky it had a 'channel' in the bottom and then a ledge a bit higher up so I could squat on that and not be in the water as such.
It gets easier the older they are
Good luck with finding something that works!
