They have some household stuff, but not a huge selection. They are in a shopping center with Daiso, Target, and TJ Maxx/Home Goods. Between all of those options, you're bound to find what you're after.
Shower screens? Not sure. But, everything else they have
What Chris said basically you can walk to a dozen or so places that can fit the bill from there. It makes the shopping center a pretty good general purpose hub for supplies
