I could live without a bath. The layout of the toilet obviously bothers you so probably would someone else too - so relocating could have a positive impact on resale too. All depends how long you are planning to live in it - unless a very short amount of time - I would be tempted to do what suits you - often people like to redo stuff anyway so could put a bath back in if they wanted. I know depending on the layout of the house if the toilet was a long way away from all the bedrooms and through the kitchen that would bother me - fine for a second toilet but if there is only one I would opt for it near the bedrooms even if that meant losing the bath.
