Measure the width, depth, and height of the space beneath your sink, as well as the size of the plumbing cut‑out. Most cabinets list overall dimensions and the U‑shaped opening (e.g., 7.87" × 7.87" for TEENFON models). Ensure the cabinet’s cut‑out matches your faucet layout to avoid interference.

TEENFON offers both a drawer‑plus‑cabinet design and a larger model with three open shelves, while Bonnlo focuses on adjustable shelves and a compact footprint. HOMCOM cabinets feature a U‑shaped cut‑out and a single adjustable shelf, but they share a similar MDF construction and weight capacity of about 33 lb total. TEENFON’s models also include a dedicated drawer for small items, which Bonnlo and HOMCOM lack.

Yes, because the area under a sink is prone to humidity and occasional splashes. Most cabinets in this list use moisture‑resistant MDF (e.g., TEENFON, Bonnlo, HOMCOM) and have sealed surfaces, but the acrylic organizers from Delamu and HIHEGD are completely water‑proof and may be a better choice for very damp environments.

The TEENFON 35.4" model and the Bonnlo cabinet both offer adjustable shelves with multiple height settings. TEENFON provides two shelves with three height options each, while Bonnlo includes an adjustable shelf that can be set at three positions. HOMCOM and kleankin also have adjustable shelves, but only a single shelf per unit.

Weight capacities vary: HOMCOM and kleankin cabinets hold up to 33 lb total (about 11 lb per shelf), while the kleankin model is rated for 66 lb total but only 9 lb per shelf. TEENFON and Bonnlo do not list explicit limits, but their MDF construction typically supports 30‑35 lb overall. For heavy items like towels, choose a cabinet with a higher total capacity.

Yes, the Delamu 2‑tier organizer, Vtopmart 4‑pack, and HIHEGD sets feature slide‑out drawers and clear acrylic compartments. These are ideal for quick access to cosmetics, meds, or small toiletries, whereas traditional cabinets like TEENFON and HOMCOM rely on shelves and doors. Drawer organizers also often include anti‑slip pads for stability.

For tight spaces, the Bonnlo cabinet provides a compact footprint (23 5/8" × 11 7/16" × 23 5/8") with an adjustable shelf and a 12‑month warranty at a modest price. TEENFON’s smaller model is similarly sized but adds a drawer for extra organization, giving slightly more utility for a comparable cost. Acrylic drawer sets like Delamu are cheaper per unit but require assembly of multiple pieces.

Bonnlo offers a 12‑month warranty and 24‑hour customer service, while TEENFON provides a 100 % satisfaction guarantee with 24‑hour response. HOMCOM also lists 24‑hour support and a warranty period, though the exact length isn’t specified. Choosing a brand with clear after‑sales support can help resolve any assembly or durability issues.
