Tile v. pre-fab shower walls for tenants

[Kelly N.]

We're purchasing a single family home to use as a rental property, and the master shower needs to be replaced. It's a one-story home with a crawlspace and the shower previously leaked, causing damage to wood under the house.

My question is whether it makes more sense to have the shower re-tiled or just throw in a pre-fab shower kit. In my mind, tenants might not keep the grout clean so the kit seems to make more sense (if we can find the right size). Any recommendations?
