Feature Highlights

Space Optimization

Smart Compact Footprint

Measuring 1400mm x 820mm x 520mm, the Grandisimo bath is the ultimate space-saving solution for modern townhouses and compact apartment bathrooms.

Its cleverly engineered interior profile boasts optimized depth and upright wall steepness, allowing for a deep, full-body soak while occupying minimal floor real estate.

Material Excellence

High-Grade Sanitary Acrylic Shell

Built from premium-grade heavy-duty sanitary acrylic, this bathtub offers an exceptionally smooth, non-porous gloss surface that is highly resistant to scratching, staining, and UV yellowing.

The thick, robust acrylic composite also acts as a natural thermal barrier, ensuring your hot bathwater retains its temperature for much longer, reducing the need for constant top-ups.

High-Grade Sanitary Acrylic Material Detail

Modern Aesthetics & Trust

Structured Rectangle Form with Warranty

The crisp, geometric lines of the rectangle silhouette bring a highly modern, architectural structure into any bathroom layout, aligning beautifully with tiling patterns and tiled hobs.

Backed by an incredible 15-year official manufacturing shell warranty, the Grandisimo represents long-term peace of mind and enduring luxury performance that stands up to heavy everyday family use.

📑 Waste & Hose Not Included: Pop-up waste and drainage plumbing hardware must be purchased separately.
* Crucial Pre-Construction Notice: Bathtub specifications may vary slightly from batch to batch. Please ensure your licensed plumber or builder measures the actual physical bathtub on-site before finalizing the framing layout, tiling, and waterproofing.

Built-In Baths FAQs

What are the benefits of a built-in bathtub?

Built-in tubs offer a sleek, integrated look for both compact and large bathrooms. They are stable, space-efficient, and often allow for extra features like storage, shower-over-bath options, or spa jets. Many homeowners also choose drop in bathroom tubs for their flexibility in design, as they can be installed within custom surrounds or decking to match different bathroom styles. An inset bath is especially valued for its clean, flush installation within a framed structure, creating a seamless and modern finish. With an enclosed design, you also enjoy easier cleaning and prevent water splashing onto the bathroom floor.

What is the lifespan of a built-in bathtub?

How long a built-in bathtub lasts depends on the material and maintenance. Acrylic and fibreglass baths usually last 10–15 years, while stone or cast iron models can exceed 25 years. Regular cleaning, avoiding harsh chemicals, and maintaining sealants extend durability, keeping your bath safe, functional, and attractive for decades.

How do I choose the right size built-in bathtub?

To choose the right size, consider:
Bathroom space: Measure length, width, and clearance for movement.
User needs: Taller users may need a longer tub; families may need a deeper or wider one.
Purpose: Quick daily use suits standard tubs; spa-style relaxation benefits from larger, deeper designs, such as a spacious drop in bathtub designed for soaking comfort.
