Question: Shower in Rental

[Stephanie D.]

Hi BP!  I'm closing on a property next Thursday that will be a rental.  I'm concerned because it has a shower and not a bath tub.  The issue is that there is a shower rod and not a glass door to enclose the shower.  I know for a fact that this set up is not idea...water easily escapes the shower with just a curtain (I have the same issue at my primary residence).  I think the area is too short to have an actual tub, which is probably why they opted for a shower...I don't think there's 5 feet there.  

Do you recommend putting in a glass shower door so that the floor, subfloor, walls and molding don't get water damage?  Or does that sound like a bad idea in a low-income rental?  The worst I imagined was putting up a $300 door that they somehow manage to break or otherwise destroy.  I

If you wouldn't put in the shower door, what would you do?  What are the alternatives if the space is too small for a tub?

Thanks!!!
