Design House Brookings 42" Sink Base Cabinet vs Horizon 18" Unfinished RTA Base Cabinet

Buy the Design House Brookings 42-inch sink base if you need a wide cabinet under a kitchen sink; its two soft-close doors and single drawer fit a 42-inch opening and the unfinished birch takes paint or stain. Buy the US-B18 Horizon if you need a narrow 18-inch base for a tight run or a filler cabinet; it has a single door, one drawer and three adjustable shelves. Both are unfinished ready-to-assemble plywood-box cabinets with soft-close hardware, so the choice comes down to width and layout, not build quality. Owners of similar RTA lines praise the soft-close doors and sturdy plywood boxes, but note that assembly and finishing take time and that unfinished fronts need sealing before use near water.

  • Choose the Design House Brookings if you are fitting a 42-inch sink base and want two doors plus a drawer in one unit.
  • Choose the US-B18 Horizon if you need an 18-inch single-door base with adjustable shelves for a narrow space.

Questions and answers

Which is better for a kitchen sink?
The Design House Brookings. At 42 inches wide with two doors and no shelves, it leaves open space for a sink basin and plumbing. The US-B18 Horizon is 18 inches wide and has shelves, so it suits storage, not a sink.
Which has better drawer hardware?
The US-B18 Horizon. It uses a full-extension soft-close under-mount glide. The Brookings has a standard drawer without those features.
Which lasts longer?
Both use 1/2-inch plywood boxes and solid wood door frames, so lifespan is similar. The Horizon adds a clear-coated maple interior and full-overlay doors, which hold up well in daily use.
Is the 42-inch cabinet worth stepping up to over the 18-inch?
Only if your layout needs a sink base. The Brookings gives you a wide two-door unit for a sink, while the Horizon gives you a narrow storage cabinet with shelves. They serve different jobs, so match the width to your opening.
Do both need finishing?
Yes. Both arrive unfinished and need paint or stain. Seal the fronts and edges before use, especially near a sink where moisture is common.
Can I combine them in one kitchen?
Yes. Both are unfinished ready-to-assemble cabinets at 34.5 inches high and 24 inches deep, so they line up in the same run. Finish them the same way to match.
