300 gallon Cedar Rain Bench DIY kit as seen on Tiny House Nation, liners, specialty fittings and detailed plans supplied by yours truly here at Second Rain. Why does this one cost more than the 280 gal DIY kit? It actually has 3 liners (up to 140 gallons each), can be built to hold 420 gallons at 32" tall, but the plans show how to build a more comfy cedar bench. Having a beautiful seat is the trade off for not filling them to capacity, that's all. Includes 3 liners, fittings, diverter, and plans with shopping list to buy local cedar and build your own.
