I guess it depends on what your guests llike I love a bath tub so when I visit our kids for instance i am always glad they have a tub in the guest bathroom but we rent the same apt. all the time in Paris and there is only a shower and I survive. I think if you have guests that have a preference and they come often maybe ask them .

Speaking solely for me, myself and I, all three of us prefer a walk in shower to a tub. The older we get, the less inclined we are to clamber into a bathtub. I know that, in his later years, my dad simply couldn't get into a tub at all, so if you have older relatives visiting, bear that in mind.

One of the greatest privileges I have is a bathroom to myself. While we have a master bathroom, the main bathroom and a 1/2 bath we also have another full bathroom. That bathroom I have commandeered as mine. It's where I'm allowed to bring out my inner fem without worrying about impugning on my husbands or sons sensibilities or masculinity.

So in answer to your question. If you don't plan on having overnight guests very frequently. Consider a retreat for just you.
