Transform Your Tub into a Shower with Grandform in Just 8 Hours 2026

Lifestyles are constantly evolving, driven by new needs that impact daily routines and overturn old preferences. Today, more and more people prefer a shower to a bathtub for practicality and water conservation. Often, this leads to hybrid solutions—a tub with a makeshift curtain or a poorly fitted enclosure—thinking that a full bathroom renovation is otherwise required.

Thanks to a new, less invasive intervention method, the switch from bathtub to shower now happens within a single day—the same time it takes to paint a room. With the Grandform G-magic program, you can choose between two product lines offering different shower trays based on available space. For this installation, the more complete version was selected, which includes replacing the faucet with a new thermostatic mixer and mounting a complete hand shower and rainhead set. The basic version, on the other hand, keeps the existing faucet and only installs the hand shower riser. In both cases, the un-tiled area is covered with laminated polyurethane panels, the tray is acrylic with polyurethane reinforcement, and the glass panels are 8 mm thick with anti-limescale treatment on both sides. The enclosure frame is aluminum with a chrome finish. No intervention is needed to match the existing tile or flooring—everything happens as if it were a brand-new installation.

The metal profiles are ultra-thin, and the handle is reduced to a simple ring, allowing for an all-glass view and minimal visual impact even in small bathrooms. All details are chrome-plated for a polished aesthetic and easy cleaning.

Why Choose a Walk-In Shower Over a Bathtub?

• Space efficiency: A shower takes up less room, making your bathroom feel larger.
• Water savings: Showers use significantly less water than baths.
• Accessibility: Step-in trays are safer for all ages and abilities.
• Modern style: Sleek designs like those from Grandform upgrade your bathroom instantly.
