We have a tiny bathroom with only a shower, no bath and when we bought it I said to DH that I'd want a bath installed (originally didn't want to even look at the house but DH insisted)
Anyway, 3 years later we are finally ready to do something and I am now thinking maybe it's too small for a bath in it! It's in a p shape with a little bit of 'hall' so it looks a bit bigger than it actually is but the actual square part of the bathroom is 190cm x 170cm, is that too small?
Its a 2 bed terrace in London so generally a first home with small kids etc type house but if we put a bath in there isn't really room for cupboards so nowhere to store towels etc.
I don't know what to do as I'd hate to spend all that money and then regret it and want to rip it out and put a shower only back in! 
What do you think, will it work?
