Undersink Organizer – Complete Review 2025
The madesmart 2 Tier Bath Organizer is a top-rated undersink organizer that transforms chaotic bathroom cabinets into neatly arranged storage spaces. This two-level system features sliding baskets and adjustable dividers, making it one of the most versatile under cabinet organization solutions available today.
If you’ve been struggling with cluttered pipes, toppled bottles, and wasted vertical space beneath your sink, this product promises a practical fix. According to madesmart, the unit was specifically engineered to maximize hard-to-reach areas while keeping bathroom essentials storage effortless.
In this review, we’ll break down every detail — from build quality and real-world usability to how it stacks up against the competition. By the end, you’ll know exactly whether this model deserves a spot in your home.
Key Features of the Undersink Organizer
This madesmart model packs several thoughtful design elements into a compact footprint. Here are the standout features that set it apart from generic bathroom cabinet storage solutions:
- Two-Tier Sliding Baskets: Both levels feature removable storage bins that slide out smoothly, giving you instant access to items tucked in the back. No more blindly reaching around plumbing pipes.
- Adjustable Dividers: Each basket includes two movable dividers, allowing you to create custom compartments for bottles, sponges, cleaning supplies, and smaller bathroom essentials.
- BPA-Free Durable Plastic: The unit is constructed from high-quality, BPA-free material that resists moisture — critical for humid under cabinet organization environments.
- Dry-Erase Labeling Areas: Built-in labeling surfaces on the baskets and dividers let you categorize items without adhesive labels, keeping things neat and flexible.
The space saving storage design measures 14.38 x 9.00 x 10.63 inches when assembled. It’s compact enough for most standard vanities yet tall enough to take advantage of otherwise wasted vertical space.
Real-World Performance Testing
We installed the madesmart undersink organizer beneath a standard 24-inch bathroom vanity to test fit, functionality, and daily usability over a 30-day period. Assembly took under five minutes with no tools required — the frame simply snaps together.
The pull out drawers glide effortlessly, even when loaded with full-size shampoo bottles, cleaning sprays, and first-aid supplies. Each basket comfortably held 8–10 standard-sized products without jamming or tipping. The adjustable dividers stayed firmly in place throughout our testing and didn’t shift during daily use.
One noticeable strength is how the tiered layout doubles your usable storage compared to stacking items directly on the cabinet floor. We measured approximately 85% more accessible space after installation.

As noted by Apartment Therapy, madesmart products consistently earn praise for their intuitive sliding mechanisms and thoughtful layouts.
However, there are a couple of limitations worth mentioning. The frost-colored plastic can show water spots if not wiped periodically. Additionally, the baskets are best suited for lightweight to medium-weight items — heavy glass bottles caused slight bowing on the lower tier over time.
How It Compares to Alternatives
Compared to the SimpleHouseware 2-Tier Sliding Cabinet Basket, this madesmart model offers adjustable dividers — a feature the SimpleHouseware version lacks entirely. The SimpleHouseware option is slightly cheaper at around $18, but it provides less customization for separating bathroom essentials.
The Spicy Shelf Expandable Under Sink Organizer takes a different approach with a stackable shelf design. While it accommodates plumbing pipes better, it doesn’t include sliding baskets, making daily access less convenient. For those who want a deep dive into more options, our complete under sink organizers guide covers the top picks across every price range.
At roughly $25, the madesmart unit sits in a sweet spot — offering premium features like removable storage bins and dry-erase labeling that competitors at the same price point simply don’t match.
Who Should Buy This Product?
Small bathroom owners: If you’re working with a compact vanity and need to maximize every square inch, this two-tier system is ideal. It turns dead space into functional bathroom cabinet storage without any permanent modifications.
Renters: Since it requires zero installation and leaves no marks, this model is perfect for anyone who can’t drill into cabinets. For more renter-friendly solutions, see our bathroom storage organizers for renters roundup.
Multi-use organizers: Beyond the bathroom, this product works equally well in kitchen cabinets, pantries, and even on desks. According to madesmart’s product page, it’s designed for multipurpose use across the entire home.
Who should skip it? If your under-sink area has bulky or irregular plumbing that takes up most of the cabinet floor, this rigid-frame design may not fit. Consider a flexible expandable shelf instead.
