Measure the width, depth, and height of the space under your sink, including any plumbing obstacles. Compare those dimensions with each product’s specs – for example, Delamu offers Small (8.27" × 13.19" × 9.06") and Large (8.27" × 13.19" × 10.63") options, while Vtopmart’s unit is 11.8" L × 7.5" W × 10" H. Choose a size that fits comfortably while leaving a few centimeters of clearance for easy drawer operation.

Pull‑out drawer systems like Delamu, Vtopmart, and HIHEGD give quick visual access and are ideal for small items such as cosmetics or spices. Full cabinets such as Bonnlo, TEENFON, and HOMCOM provide enclosed storage, adjustable shelves, and higher weight capacity for towels and bulk toiletries. Drawers excel in visibility, while cabinets excel in protection from moisture and larger load handling.

Acrylic and thick polycarbonate (used by Delamu and HIHEGD) resist water stains and stay clear for easy identification. High‑hardness ABS plastic (HIHEGD) and stainless‑steel reinforced PET (Vtopmart) also handle humidity well and won’t rust. MDF cabinets (Bonnlo, TEENFON, HOMCOM) are moisture‑treated but may swell over time if exposed to constant splashes.

Load capacity determines whether the unit can hold heavier items like bulk cleaning supplies or stacked towels. Cabinet models typically list higher limits – HOMCOM and TEENFON support up to 33 lb total, while drawer organizers often cap at 15 lb per drawer (Vtopmart). If you plan to store heavier products, prioritize a cabinet with a solid shelf rating.

Stackable designs such as Delamu’s and the Ukeetap set let you expand storage vertically without buying a larger single unit, which can be more economical for tight spaces. They also maintain a uniform look and keep items visible. The trade‑off is a slightly higher initial price and the need to ensure the stacked units remain stable on the countertop.

Clear acrylic provides a crystal‑clear view of contents and feels premium, but it can be more prone to scratches. PET (used by Vtopmart) is lightweight, shatter‑resistant, and still transparent, while high‑hardness ABS (HIHEGD) is tougher and more impact‑proof but may have a slight tint. Choose acrylic for aesthetics, PET for durability, or ABS for the toughest everyday use.

Measure the U‑shaped cutout required for plumbing; most cabinets list exact dimensions (e.g., HOMCOM’s 8.75" L × 7.5" W). Ensure the unit includes non‑slip silicone pads or feet to prevent movement when drawers are pulled. Most cabinet kits come with pre‑drilled holes and hardware, but you may need a screwdriver and a level to keep doors aligned.

For tight spaces, Vtopmart’s 2‑tier clear drawer set offers a low price, sturdy stainless‑steel rods, and a 15 lb drawer capacity, making it a solid value. If you need more vertical space and the ability to stack, Delamu’s acrylic organizer gives visibility and modularity at a modest premium. Consider your load needs and whether you prefer drawers or a closed cabinet to decide the best value.
