To save money and conserve water, I decided that we needed a rain barrel. I did some research online looking at commercial options and I didn't care for some design elements (ex. why have the faucet a foot from the bottom of the barrel?) and I didn't really like the costs at all. The homemade versions seemed like a better value (like this one [link below] from Better Homes & Gardens) which I could build with better materials the way that I wanted (vs. commercial):

The other thing that I noticed is that many people will buy a rain barrel or build one and then precariously balance the very heavy barrel on a cinder block or stack of bricks or something equally unstable which seemed like a safety hazard to me (especially with young kids). With my own rain barrel stand, I could put the faucet very low on the barrel to maximize the water that comes out and have a much safer + more stable platform, as well.
OK, here's my version:
You need a few parts which are available from a big orange hardware store.
1/2" Faucet Rosette Washer + Nut
Male No-Kink Hose Bibb (aka faucet)
Rubber O-rings to fit the "bibb"
Silicone sealant
Screen or landscape fabric
Drill + large bits (big enough to fit the "bibb")
Barrel
The "Male No-Kink Hose Bibb" has a bit of angle to which you attach the hose which appealed to me. I'm not sure if this will really make it "no-kink", but a little bit of an angle seemed like a good idea (vs. straight down to the ground). For my first rain barrel, I don't plan to attach a hose - it's just going to be for filling a watering can so the "no-kink" is less of a concern for me.
The really neat part of this system is the Faucet Rossette Washer + Nut sink repair kit. This little guy screws together which helps seat the faucet + the o-rings into the barrel and leaves very little work for the silicone to do (in terms of holding back water and preventing unwanted leakage).
And, of course, you'll need a barrel + drill. You could use any old barrel, but I chose the Rubbermaid Brute 32-gallon because it's made of thicker plastic. For some unknown reason, most of the Brute trash barrels are sold without a lid, so you'll need to buy a lid anyway....and you might as well buy a flat lid. I also liked the smaller 32-gallon size which will be plenty for my needs.
In terms of the stand, I took two, 4x4x8 PT posts, cut them in half, sunk 2' of the 4' posts into post holes that I dug with a post-hole digger, then built a 2x4 platform for the barrel to sit on, and a 2x4 railing on top secured with 2 1/2" blue-kote (weather-resistant), course kreg screws. Simple, right?
After building my first rain barrel, I'm going to try a few more ideas on version 2. The landscaping fabric that I used was very heavy duty, so heavy duty that it's almost water proof. You're really better off with screen material or cheap, flimsy landscape fabric which will be much more porous. When I replace some screens on my sliding doors, I'll save the old screening material and use it for rain barrels. Also, positioning of the rain barrel is very important. I chose a location with a sloped roof, but I didn't account for how the rain would drip off the roof in a variable way with certain spots collecting most of the drips. I could fix this by installing a drip edge or gutter to collect and direct the rain, but I'm not sure that's necessary for just filling a few watering cans. However, for my vegetable garden, I'm going to need some sort of collection system to divert water into the rain barrel....more on that in another blog post.
