Installing a Storage Rack in a Bathroom Vanity

Filed under: Carpentry — Gilles @ 5:23 am

A rolling storage rack is installed in a bathroom vanity. Faucet supply lines are tied up to the underside of the counter top.


Skill Level: 2 (Basic)

Time Taken: About 30 minutes

The sliding rack to install. This “ClosetMaid In-Cabinet 3-Tray Pull Out” was purchased from the discontinued section of Lowes for about $25 (Reg. $60). From top to bottom:

  • The rack,
  • Two heavy duty, full extension sliders,
  • Paper template and hardware for installation.

This rack is designed for kitchen cabinets and not for bathroom vanities but in our house, we have kitchen cabinets as vanities in bathrooms so there was a chance this would work.

Left: The vanity of interest. Doors have been temporarily removed to facilitate access. I have also setup a fluorescent light. Vanities have to account for plumbing and rarely offer sufficient storage. My task is to add storage space using the rack.

I started by reading installation instructions and taking some measurements. It first looked that the rack would best fit on the left of the vanity.

Right: The kit comes with a cardboard template for easy installation. I marked determined the centerline of the template and marked it with a pencil.

Left: The cabinet has a face frame so I measured the opening and calculated the centerline of the opening.



Right: I marked the centerline on the bottom of the cabinet with a pencil. This can later be removed using an all purpose household cleaner like “Simple Green”.

Left: I aligned the centerline of the template onto the centerline of the cabinet. After precisely locating the template, I held it in place with masking tape.

Right: I positioned sliders as indicated on the installation instructions. I did not fasten or drill anything.

I want to perform a dry run and see if the rack will fit and operate properly before I commit to installing here.

Left: I installed the rack over the sliders, still without fastening anything. It seemed to fit fine BUT …


Right: … the rack hit the hot water supply stop valve. Clearly this is not going to work. Not drilling or fastening anything has paid off.

I decided to try to install in the right side of the vanity.

Left: I repeated all the previous steps in the right bay of the vanity. This time, the rack had enough clearance to function properly or …

Right: … does it? Flexible water supply lines somewhat conflicted with the rack. I decided to move them out of the way.

Left: I rolled of plastic plumber’s perforated tape. Plumbers sometimes use this to hold pipes securely. Since it is made out of plastic, it does not damage pipes when thy rub on it.


Right: I cut a piece of the tape and secured it to the underside of the counter tiled top with a 1/2’’ wood screw.

The counter top is tiled by someone who decided to use 1/2’’ OSB as a substrate for 1/4’’ hardibacker and tiles.


Left: I secured the other side of the plumber’s tape.


Right: Flexible hoses are now held close to the countertop. Note how I was careful to avoid kinking hoses. I also ensured that the bend radius of those hoses was very large, to avoid damaging them.



Left: With hoses out of the way, I marked where sliders would be screwed to the bottom of the cabinet and pre-drilled all holes with a 1/8’’ diameter drill bit, as requested by installation instructions.


Right: I secured sliders to the bottom of the cabinet using the provider screws and my impact driver.

I removed the template and cleaned up the saw dust.


The tray was installed on sliders. There are four metal tabs (one at each corner) which need to be bent to secure the tray to the sliders. The manufacturer request those to be bent for a permanent installation.

I did not immediately bend those because I plan to add shelving to the other side of the vanity and in doing so, I may need to remove the tray temporarily.
