Design & Placement Options
Large 1800mm bathtubs offer space to truly unwind, perfect for open-plan bathrooms, luxurious ensuites, or anyone who values full-length comfort. Choose a layout that complements your room and makes the most of your bath's scale.
Freestanding Bath: The statement piece of any large bathroom. With space all around, a freestanding tub becomes a sculptural focal point, especially when paired with floor-mounted spouts and ambient lighting. Ideal for open layouts or centred under windows.
Back-to-Wall Bath: A space-efficient way to enjoy the size and shape of a freestanding bath, while keeping the rear edge flush to the wall for easy cleaning and smart tap placement. Perfect for family bathrooms where function and form go together.
Island Bath: Designed to be placed away from walls, island baths offer 360-degree presence and create a true focal point in larger bathrooms. Ideal for open-plan layouts, they pair beautifully with floor-mounted mixers and surrounding space for movement, styling, or freestanding accessories.
Styles & Profiles
Oversized Oval: Fluid, organic lines that support the body and soften strong architectural elements. Great for longer soaks and relaxed, open-plan layouts.
Extra-Long Rectangle: Defined edges and a minimalist silhouette make this a natural fit for modern or industrial-style spaces. Pair with square wall mixers and clean-lined vanities.
Double-Slipper Profile: Raised ends on both sides create perfect symmetry and allow two people to recline comfortably. Ideal for couples or anyone seeking a dual-soak experience.
Materials & Finishes
Solid Surface (Cast Stone): Ideal for larger baths thanks to its heat-retentive density. Holds warmth longer and feels velvety to the touch. A matte finish adds softness to bold forms.
Gloss Acrylic: A lightweight option for larger forms, especially in multi-storey homes. Easy to clean, easy to install, and a timeless match for chrome or white tapware.
Coordination & Accessories
Complete the space with accessories designed to enhance both function and flow around your bath:
-
Wall-Mounted Tapware: Best for back-to-wall and corner installations where floor space is limited.
-
Floor-Mounted Mixers: Ideal beside freestanding or fluted tubs, especially when placed at the tub's widest access point.
-
Towel Rails & Hooks: Position beside slipper or rectangular tubs for easy reach. Opt for heated options in family bathrooms or colder zones.
-
Bathroom Shelves & Niches: Install behind or beside back-to-wall tubs to keep soaps, brushes, and bath oils within arm's reach without clutter.
