This is not a simple add-on cabinet — this is a complete vanity replacement that includes a ceramic basin, pre-drilled three-hole faucet mount, and two door cabinets with a drawer. At 24.5 inches wide and 34 inches tall, it provides genuine countertop space and a proper sink, making it the most comprehensive solution for anyone willing to swap out an old pedestal. The soft-close hinges on both the doors and the drawer eliminate the hollow slam that cheap cabinets produce.

The ceramic basin holds up to 66 pounds, and the shelf supports the same weight, while the drawer manages up to 44 pounds — numbers that dwarf typical add-on cabinets. Build time averages around one hour per owner reports, with clear instructions for plumbing integration. The pre-drilled three holes accept any standard 4-inch center-set faucet, and the floor-protective pads prevent scratching tile surfaces.

The only trade-off is plumbing compatibility: some users reported needing to cut access holes or use wedges to avoid interfering with existing pipe runs. Measure the height from your floor drain to your water supply — it should fall between 18.3 and 26.4 inches for proper installation. This unit delivers permanent bathroom storage, not a temporary cover-up.

The Bellemave stands apart because it uses a solid wood frame rather than entirely engineered board. The 30-inch width provides a more generous countertop presence, and the integrated pure-white ceramic sink features three pre-drilled holes for a 4-inch center-set faucet plus a protective overflow with a metal ring. Smart partitions inside the single drawer keep cosmetics and grooming tools organized without sliding around.

The most distinctive feature here is the built-in shelving inside both cabinet doors — small ledges designed to hold smaller items like razors, shampoo bottles, or makeup tubes vertically rather than letting them pile up on the floor. The soft-closing hinges on both doors are adjustable, so you can fine-tune the alignment if the cabinet settles slightly after installation. The water-resistant paint on both interior and exterior panels resists the humidity and splashes that degrade raw MDF over time.

Multiple owners noted that the wood material feels lighter than expected, but the overall build quality is high for the price category. Assembly remains straightforward, and the packaging includes extra parts in case of damaged hardware. If you want a complete vanity system that maximizes internal organization through door shelving, this is the smarter buy over a standard two-door unit.

The TEENFON stands out because it adds a splash of color — Forest Green — to a category dominated by white and black. The U-shape cutout measures 7.9 by 7.9 inches, which accommodates most standard pedestal columns. The MDF surface is treated with a waterproof, moisture-resistant coating, which directly addresses the biggest enemy of any under-sink cabinet: condensation and accidental splashes from hand washing.

Assembly time runs between 20 and 30 minutes, aided by labeled parts and a simple structure. A 33-pound total weight capacity and 11-pound per-shelf limit match the HOMCOM unit, but the moisture-resistant surface gives it an advantage in humid bathrooms. The anti-tipping hardware included with the package adds safety, especially in households with small children who may lean on the cabinet doors.

One buyer reported over 200 separate pieces in the box, which contradicts the generally positive assembly experience. The color is the real draw here — this is the only cabinet in the group that offers a non-neutral finish, making it a focal point rather than an invisible storage box. If you want your under-sink cabinet to contribute to the room’s aesthetic, the Forest Green TEENFON delivers.

The kleankin Antique White cabinet introduces a walnut wood grain top surface that bridges the gap between a utilitarian add-on and a finished piece of bathroom furniture. The recessed door panels mimic Shaker cabinet styling, and the elevated legs lift the unit 3.25 inches off the floor, providing a gap that prevents base water damage and makes cleaning underneath feasible. The U-cutout measures 7.75 inches wide by 8.75 inches deep.

Weight capacity sits at 22 pounds total with only 6 pounds per shelf — notably lower than the TEENFON or HOMCOM cabinets. This limits storage to lighter items like toilet paper rolls, hand towels, and small soap bottles rather than heavy multi-packs. The adjustable shelf is a welcome feature for customizing the interior layout, and the anti-tipping hardware secures the unit to the wall for child safety.

Assembly is generally described as straightforward, though the particle board construction makes over-torquing screws risky with power tools. One owner called it “rentier-friendly storage” — easy to install and easy to leave behind for the next tenant without feeling like you gave up anything. The walnut top provides a visual anchor that a plain painted cabinet cannot match.

The HOMCOM Black cabinet delivers the highest total weight capacity in the budget tier at 33 pounds, with 11 pounds per shelf. The U-shape opening measures 8.75 inches long by 7.5 inches wide — slightly longer than most competitors, which helps if your pedestal base has a broader depth profile. The beadboard door style adds texture that reads more expensive than the actual build cost suggests.

Assembly time averages 40 minutes, with clear instructions and pre-labeled parts. The adjustable shelf can be moved up or down in 1-inch increments, making it easy to accommodate tall bottles on one side and stacked towels on the other. The anti-tipping hardware is included and should be used, especially with a 33-pound top load. Black is a safe choice that blends into darker bathrooms or adds contrast to white fixtures.

Some owners found the hinge holes not pre-drilled and the magnetic door stops misaligned, which suggests quality control varies by batch. The unit sits only 0.75 inches off the ground, so any spill on the bathroom floor will wick into the MDF bottom edge. For a pure no-frills cabinet that maximizes internal storage volume per dollar, this is the budget winner.

This kleankin White cabinet differentiates itself with a U-shape cutout designed for a washbasin base of 19.75 inches long by 7.75 inches wide, plus an open shelf beneath the enclosed cabinet. The open shelf provides quick-access storage for frequently used items like a hand towel or soap dispenser without opening the doors. The slow-close doors are a genuine surprise at this price point — they dampen the closing motion instead of slamming.

Assembly runs about 30 minutes for experienced builders, but the picture-only instructions require careful interpretation. Step 6 in particular has an incorrect screw-to-peg diagram that can confuse first-time builders. The engineered wood construction feels solid for the price category, and the recessed beadboard door style matches the HOMCOM’s aesthetic appeal. The painted white finish blends seamlessly with standard bathroom fixtures.

Several owners reported needing to cut the U-shaped opening larger with a jigsaw because the pedestal base was thicker than expected. Measure the actual pedestal column width before committing to this cabinet — if your sink base exceeds 7.75 inches, you will need to modify the cabinet. The slow-close doors add a touch of quiet sophistication that most budget cabinets lack entirely.

The VonHaus unit has the most compact dimensions in the lineup — the top depth is only 23.5 centimeters (roughly 9.25 inches), and the base depth is 21.5 centimeters (about 8.5 inches). This narrow profile is ideal for half-baths or powder rooms where the sink is shallow and a standard 11.75-inch deep cabinet would protrude too far. The Shaker-style doors and chrome handles give it a modern, clean look that fits contemporary bathrooms.

A water-resistant finish protects the engineered wood from everyday moisture, and the adjustable shelf lets you fine-tune interior space. The included anti-tipping kit should be used, especially if the cabinet is placed on smooth tile where it could shift. Assembly is straightforward, with screws used for the backboard instead of nails — a small quality detail that makes disassembly less destructive if you move.

The most common issue reported is the bottom hinge lacking a pre-drilled pilot hole, causing doors to slip off alignment over time. Some owners drilled their own hole to fix this. The unit fits pedestal bases up to 9 inches wide at the column, which is slightly more accommodating than some competitors. If your bathroom has a shallow under-sink cavity, the VonHaus may be the only cabinet that physically fits.
