They are included, depending on your surface, you might get heavier ones. We did.
Thank you. 3 inches.
The bar and the pieces on the ends are metal, as are the plates that are screwed into the wall to anchor everything.
Thank you. It can be installed in tile using a tile drill bit.
All the ones I've seen, including the 24" bar I tested, have side by side mounting screw holes - like those in your picture - with the set screw on the bottom. I can't say for sure that the distance between the holes is universal, but if the old towel bar isn't more than 25 years old, there's a good chance a new set will work in the existing holes. Measure as many times as you need and remember most everything at Home Depot is exchangeable if it doesn't fit.
Please get anchor screws, self drill into the wall, set your hanging brackets accordingly; enter one end, install the rod, then install other end, simple.
It is three pieces. Comes with an easy install wall template, two end pieces and the bar. VERY easy install!
Thank you. That measurement is 3 inches.
Thank you. This towel bar has a weight capacity of 15 pounds.
