This Hidden Bathroom Storage Idea Uses Space Most Homes Completely Ignore — And It’s Brilliant
Small bathrooms almost always struggle with the same problem: there is never enough storage. Towels pile up, cleaning supplies end up squeezed into random cabinets, and toiletries slowly take over every available shelf.
But one clever design trick is starting to gain attention among homeowners and designers alike. Instead of leaving the bathtub panel as a simple cover, some bathrooms are now turning that space into a hidden pull-out drawer built directly under the tub. We first spotted this brilliant idea on Instagram from @mk.imperium, where the simple modification turns an overlooked part of the bathroom into highly functional storage.
At first glance, the bathtub looks completely normal. The front panel sits flush with the tub, maintaining a clean and minimal appearance. But when the panel is pulled forward, it reveals a large concealed drawer that runs along the base of the bathtub.
For small bathrooms, this simple modification unlocks storage in a place that normally goes completely unused.
A Smart Way to Use the Empty Space Under the Tub
Most built-in bathtubs already have a hollow cavity beneath them. In traditional installations, the front panel simply hides plumbing and framing.
By mounting that panel on heavy-duty drawer slides, the entire section can become a functional storage drawer instead of a fixed cover.
Because the drawer spans the full width of the tub, it creates a surprisingly deep storage compartment that can easily hold:
- folded bath towels
- bath salts and bath products
- extra toiletries
- cleaning supplies
- spare toilet paper
In many cases, this hidden drawer provides more storage than a typical bathroom cabinet, without adding anything new to the room.
The Bathtub Does Not Sit on the Drawer
One important detail is that the bathtub itself does not rest on the drawer system.
A filled bathtub can easily weigh 250–300 kg once water and a person are inside, so the tub must always be supported by its own structural system. Most modern tubs sit on adjustable metal legs or a steel support frame, which transfers the weight directly to the floor.
The drawer simply occupies the empty space inside the tub enclosure. It slides out from the front panel while the bathtub remains fully supported by its frame and the surrounding structure.
This means the drawer works purely as a storage feature and does not carry any of the bathtub’s weight.
Perfect for Small Bathrooms and Apartments
This idea works especially well in compact bathrooms where floor space is limited. Adding cabinets or shelves can quickly make a small room feel crowded.
By using the space already hidden beneath the bathtub, the bathroom gains storage while still maintaining a clean and uncluttered design.
For guest bathrooms, apartments, or narrow layouts, this kind of built-in solution can make everyday organization much easier.
A Simple Upgrade That Looks Built-In
One reason this concept is becoming popular is that it can often be added during a bathroom renovation without major structural changes.
The upgrade typically involves:
- building a moisture-resistant drawer box
- installing strong drawer slides inside the tub frame
- attaching the bathtub panel as the drawer front
From the outside, the bathtub still looks like a standard installation. The storage remains completely hidden until the panel slides open.

Turning an Overlooked Space Into Something Useful
As bathroom design continues to move toward cleaner and more minimal interiors, designers are increasingly finding ways to hide storage inside existing structures.
The space under the bathtub is one of the most overlooked areas in the room. Transforming it into a drawer turns that empty cavity into a practical storage solution without changing the layout of the bathroom.
For homeowners dealing with limited space, it’s a simple idea that can make a small bathroom feel far more functional.
