Shower or bath tub in 3 bedroom

[Aleksandra U.]

I have very small bathroom to remodel. Previous owner had some weird ideas there (how about that PVC to hold a curtains?) all needs to go. Bath tub is corroded and somewhat pain to use in that type of set up. 

My contractor suggested building a shower to fit into space. He would tile everything top to bottom. 

I’m thinking small bathtub (48”) probably is a better option. One reason is tiled shower can start leaking?..

Build a wall to separate shower or bath from window and gain storage space behind. 

What’s your opinion?
