A wide cabinet on the outside; a trap, hoses and a few bottles wherever they fit on the inside. Under-sink storage can be awkward because the plumbing divides the space without regard to what you want to keep there.
A larger vanity is not always necessary. Sometimes two separate organizers are enough. Elsewhere, a drawer designed around the installation makes the interior substantially easier to use.
Map the plumbing first
Look beyond the drain trap to the underside of the basin, valves, supply hoses and connections. Their footprint changes with height. A container may fit on the floor but catch a hose above it when lifted out.
Keep valves reachable and leave room to service the trap. A small maintenance task should not require dismantling the entire cabinet. Fitting an organizer around plumbing is different from altering plumbing to suit an organizer.
A cut-out drawer starts with the design
A drawer surrounding the trap can separate small items on both sides and at the front. Its shape must match the basin and drain arrangement. A cut-out shown in a catalog will not automatically fit every installation.
In a new bathroom, plan the vanity and plumbing together. In an existing one, do not simply cut a section out of a finished drawer: this may weaken it or interfere with components needed by the slides.
A pull-out on one side
Where pipes occupy the center, a narrow pull-out may fit on the left or right. Rev-A-Shelf offers bathroom organizers with different mounting arrangements; its historical documentation for the 441 family also illustrates an L-shaped layout.
This demonstrates a storage approach, not universal cabinet compatibility. Check internal width, depth, height and hinge interference. Consider the travel outside the cabinet, especially beside a toilet or laundry basket.
Removable containers: the simplest improvement
Two or three small baskets can work around pipes more easily than one wide organizer. Give each a task: everyday care, spare toiletries or cleaning accessories. Removing a complete basket exposes the back of the cabinet and makes a leak easier to notice.
IKEA VISSLAÅN is one example of small bathroom organization accessories; the pictured item is a shallow drawer tray, so choose its intended location accordingly. On a cabinet floor, a small turntable such as YouCopia SinkSuite is another possibility. Rotation helps only if the bottles clear the pipes and can be gripped without tilting.
Two levels do not always improve access
A tiered organizer may separate small containers, but its upper shelf competes for space with the basin. Before buying, including on Amazon, check the height with toiletries in place rather than measuring only the empty frame. A metal structure does not automatically tolerate repeated soaking.
Finally, open the cabinet and take out your three most-used items. If spare supplies must be moved first, change the arrangement. Reserve the easiest area for daily needs rather than the largest backup bottle.
What causes the biggest difficulty under your sink: pipes, a lack of drawers or reaching the back?
