we bought a house without a bath, and did a later reno to put one in. The previous owners had had one earlier and removed it at some point, as their kids got older. The realestate agent said that not having a bath was a downfall for some potential buyers.

I grew up with a shower over bath, and really like them. I actually wanted to put in an extra showerhead over our bath but was outvoted. You can bath and then turn the shower on to rinse your hair in clean water, or shower off the grot and then put the plug in and relax for awhile, or have kids bathing while you shower in the other end.

When we put our bath in, we extended the bathroom by stealing space from a bedroom, and this room is now a study.
