What is a better investment shower or tub??? i am planning on remodeling my parents guest bathroom at some point....

i am planning on remodeling my parents guest bathroom at some point. the 3 bedroom 2 bath house have a tiny little guest/kids bathroom with a bath/shower within it... i want to rip out everything because of its condition and i was wondering what sell better when it comes to selling the house? i could put in a big shower or put a bathtub+shower... any ideas... it would minister to if you are a realestate agent or just sold a house appreciation...
Answers:    I would stay with a bathtub/shower combination since it is the individual place for a bathtub within the house. When it comes to selling a home, it is best to keep the areas as multi-use as possible. Consider adding a bathtub/shower combo that have some luxury features like a jetted tub or massage shower head if they don't increase the cost by much. Bathroom luxury is a big trend right very soon in homes.
A bathtub/shower combination would be better because a bathroom near just a shower would lately be considered a 3/4 bathroom instead of a full bathroom.
