Overview
FCMP's Slim Line rain barrel holds 45 gallons in a flat-backed, wood-grain-finish shell built for tight spots against a house wall. It ships with spigots, a mesh debris screen, a garden hose, and a linking kit for connecting more than one barrel.
The flat back and shallow depth are the point here, since a standard round barrel does not sit flush against siding under a downspout. Side-mounted spigots let you daisy-chain several barrels together for more storage without extra plumbing, and the mesh screen keeps leaves and debris out of the water rather than just off the top. It is made in Canada from BPA-free, UV-inhibited polyethylene.
- 45 gallon slim-profile design
- Flat back for wall placement
- Side spigots for linking barrels
- BPA-free UV-inhibited polyethylene
Who it's for
Gardeners with a narrow side yard or limited space near a downspout who want water storage without a bulky round barrel. Less suited to anyone wanting large-volume storage in one unit, since 45 gallons is on the smaller side for the category.
Pros and cons
- Slim, flat-backed shape fits tight spaces against a house
- Side spigots allow linking multiple barrels together
- Mesh screen keeps debris out of stored water
- Garden hose, shut-off valve, and linking kit included
- 45 gallon capacity is modest for a single barrel
- Plastic construction, not a stone or metal finish
Performance notes
At 16 inches deep, 22 inches wide, and 32 inches tall, the barrel trades depth for a flatter footprint, and its 20 pound empty weight makes it manageable to position before filling. The side spigots and linking kit are what let multiple barrels share overflow, so capacity scales by adding units rather than by buying one oversized barrel.
