Small bathrooms almost always struggle with the same problem: there’s never enough storage space. Towels pile up, cleaning supplies end up crammed into random cupboards, and toiletries slowly take over every available shelf.
But one clever design trick is starting to gain attention among homeowners and designers. Instead of leaving the tub panel as a simple cover, some bathrooms are now turning this space into a hidden pull-out drawer built directly under the tub. We first spotted this brilliant idea on Instagram by @mk.empirewhere a simple modification turns a neglected part of the bathroom into highly functional storage.
At first glance, the bathtub looks perfectly normal. The front panel is flush with the tub, maintaining a clean and minimalist look. But when the panel is pulled forward, it reveals a large hidden drawer that runs along the base of the tub.
For small bathrooms, this simple modification unlocks storage in space that normally goes completely unused.
A smart way to use the empty space under the bath
Most built-in bathtubs already have a hollow cavity under them. In traditional installations, the front panel simply hides the plumbing and frame.
By mounting this panel on heavy duty drawer slides, the entire section can become a functional storage drawer instead of a fixed lid.
As the drawer spans the entire width of the tub, it creates a surprisingly deep storage compartment that can easily accommodate:
- folded bath towels
- bath salts and bath products
- additional toiletries
- cleaning agents
- spare toilet paper
In many cases, this hidden drawer provides more storage space than a typical bathroom cabinet without adding anything new to the room.
The tub does not fit on the drawer
An important detail is that the tub itself does not step on the drawer system.
A filled tub can easily weigh 250-300kg once there is water and a person inside, so the tub must always be supported by its own structural system. Most modern bathtubs stand on adjustable metal legs or a steel support frame that transfers the weight directly to the floor.
The drawer simply occupies the empty space inside the tub enclosure. It slides off the front panel while the tub remains fully supported by the frame and surrounding structure.
This means that the drawer only works as a storage function and does not support the weight of the tub.
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 under the tub, the bathroom gains storage space while maintaining a clean and uncluttered design.
For guest bathrooms, apartments or tight layouts, this kind of built-in solution can make daily organization much easier.
A simple upgrade that looks built-in
One of the reasons this concept is becoming popular is that it can often be added during a bathroom renovation without major structural changes.
An upgrade usually includes:
- building a moisture-proof drawer box
- installing sturdy drawer slides inside the tub frame
- attaching the tub panel as a drawer front
From the outside, the bathtub still looks like a standard installation. The storage remains completely hidden until the panel is slid open.
Turning neglected space into something useful
As bathroom design continues to move toward cleaner, more minimal interiors, designers are increasingly finding ways to hide storage within existing structures.
The space under the bathtub is one of the most neglected areas in the room. Transforming it into a drawer turns this empty cavity into a practical storage solution without changing the layout of the bathroom.
For homeowners working with limited space, this is a simple idea that can make a small bathroom feel much more functional.
