This Rev-A-Shelf SBVDT Series drip tray sits on the floor of a vanity or base cabinet to catch drips, slow leaks, and spills before they reach the cabinet box, keeping the wood underneath dry and protected.
Plumbing connections under a vanity sink are a reliable source of slow drips, condensation, and the occasional supply-line weep. Left unaddressed, that moisture migrates into the cabinet floor and the wood or substrate beneath it. This tray sits flat on the cabinet bottom and catches what comes down, so a minor drip stays a minor drip instead of becoming a rotted cabinet floor. The Silver finish reads as a clean, neutral surface inside the cabinet, and the polystyrene material does not absorb water, so cleanup is a wipe rather than a scrub.
At 28-1/2 inches wide and 20-1/4 inches deep, this tray is sized for a standard 30-inch vanity cabinet where the clear interior opening accommodates those dimensions around the plumbing. The 3/4-inch raised perimeter keeps contained moisture from running off the tray edge. Polystyrene is a rigid, non-porous material that holds its shape under light loads, does not warp from humidity exposure, and does not transfer moisture into the wood beneath it. The Silver colorway is a mid-tone neutral that blends into the cabinet interior without drawing attention.
The primary application is a bathroom vanity where a sink drain or supply connection runs through the cabinet floor or back wall. It also works under a kitchen base cabinet sink as a first line of protection, or in a utility cabinet where cleaning supplies, sprayers, or liquid storage create occasional drip risk. Homeowners doing a bathroom renovation who want passive leak protection without a sensor or shutoff device reach for this tray. Cabinet shops and contractors spec it during new vanity installs so the protection is in place before the plumbing is ever connected. Measure the interior cabinet opening before ordering to confirm the tray dimensions fit around existing plumbing and within the cabinet walls.
Polystyrene is non-porous, so the Silver surface does not absorb moisture or develop the staining that wood or particle board floors often show. Wipe it dry after any accumulation.
The tray sits flat on the cabinet floor. Drain and supply lines that pass through the floor or back wall will interrupt the flat footprint. Measure your clear cabinet floor area and compare it to the 28-1/2 inch by 20-1/4 inch dimensions to confirm fit around your specific plumbing layout.
The 28-1/2 inch width is intended for a 30-inch nominal vanity cabinet, where the interior clear opening is typically close to that dimension. Confirm your interior opening before ordering if your vanity has a face frame or non-standard internal framing that reduces the usable floor width.
Polystyrene can be scored and cut with standard shop tools, but the source does not confirm this as a designed feature. Field modifications are at the installer's discretion.
Install this tray once and it works without sensors, batteries, or attention, keeping the cabinet floor dry and the cabinet box intact for the long run.
