I don't use my bath - except for giving houseplants a little shower - but guests use it for their children. I have a separate shower room with a large, rectangular shower and a flip-up wall seat (really useful for washing feet with my dodgy back).
I don't think that having no bath would devalue a home or put many people off. It's really quite simple to have one put in - and fairly cheap too.
Do have exactly what suits you in your home.
