Sienna and a RainBench Liner
You can buy individual liners for $49.95, less cost if purchasing larger quantities.
Our FDA approved food-grade liners are 2-ply, 8 mil (4 mil each layer) PE film, form fitted to the shape of the Rain Bench®.  They measure 32″w x 32″l x 32″h and have two fittings welded on with 2″ female PVC thread. We designed them specifically for the Rain Bench®.  They are manufactured in the USA at an ISO 9001 certified facility.
(Don’t try this at home. This was very scientific testing of a liner filled with 140 gallons of water. It passed. Combined pouncing weight: 246 lbs.)
Currently the size referred to above (32″x32″x32″) is the only one available for sale.  However, we have been developing and testing more sizes and applications which may be available at a later date. If you have any specific needs or requests, please contact us and we will try to accomodate.
(You’d be surprised how versatile this flexible liner is..)
No worries, you’re not alone. Most of this is only intimidating until you do it and realize how simple it is. Â Still, it’s not for everyone..
Please fill out the contact form, let us know about where you are and we will do our best to direct you to someone locally who is qualified to build this for you. We are also working on a searchable list of distributors in your area, which may be online as soon as I have no idea…  (better to contact us 😉
We put together the most complete set of PVC and garden hose fittings/ adapters in order to allow easy hookup to a supply line (i.e. downspout diverter or greywater system – ideally 1″ barbed fitting but also garden hose), to a garden hose (includes shut-off valve), and to an overflow fitting or line (2″ PVC or 1″ barbed fitting).
Also included are various lengths of U.V. resistant, food grade 1″ I.D. vinyl tubing and a full roll of teflon tape to seal fittings (in the standard RainBench® DIY kit) and more for the larger kits.  Generally, all you need to buy is lumber and fasteners for most of our kits unless you just buy liners..
We guarantee the liners for 2 years against any manufacturer defects (material, seams, construction) and have done extensive use and freeze/ thaw testing. (Draining your Rain Bench® for winter is still recommended) They are, however, not indestructible and therefore can be torn or punctured with sharp objects. Once inside a Rain Bench® framework, however, they are protected from most dangers as well as sunlight.
We have our own and various installations for others since spring of 2009 and have never needed to replace a liner due to a failed seal.  The only time we have heard of a replacement being needed is has been 1,  from animal damage.
Your Rain Bench® should last as long as any wooden structure that you paint or seal (i.e. a deck, wood siding, garden shed). It also needs to be placed on a bed of pea gravel or permeable paving so moisture does not sit against the base. Even if it is not properly maintained and/or needs to be replaced in 5 or 10 years, it may only cost about $15 to replace the entire framework of one standard Rain Bench®
