bathroom remodel - contractor question - builders grade

[Elizabeth L.]

Hi, I'm going through my first renovation and had a quick question as I'm less experienced in renovations. My contractor is doing a builders grade rehab on my bathroom so the deal was to replace the existing bathroom. The original shower had a sliding door on it, but this new stall shower has no door, they're saying to use a curtain because that's builders grade and a new shower door would be custom so it's expensive. Does that sounds accurate? I just find a curtain for a shower stall very tacky, and I'm trying to get maximum rent for the new apartment. I see plenty of shower door options at home depot, what do other landlords use for rentals and what is the least expensive route to go? 

Thanks!
