Rectangle Bathtubs
Rectangle baths offer a timeless silhouette with architectural clarity, perfect for contemporary spaces that favour straight lines, symmetry, and structured design.
With their flat edges and sharp geometry, these bathtubs integrate seamlessly into minimalist, modern, or urban-inspired bathrooms.
Buildmat's collection of rectangular baths spans freestanding, back-to-wall, and corner styles to suit a wide range of layouts. Whether you're after a sleek centrepiece or a space-smart installation, each design is crafted for everyday comfort, visual consistency, and effortless coordination with our bath tapware and bathroom accessories.
Design & Placement Options
Freestanding Bath: A bold architectural form ideal for open-plan bathrooms or those with symmetrical layouts. Place centrally or along a feature wall, and pair with floor-mounted mixers for maximum visual impact.
Back-to-Wall Bath: Offers the clean profile of a rectangular tub with the practical edge of wall-mounted plumbing. Perfect for family bathrooms, shared ensuites, or compact spaces where ease of access matters.
Left and Right Corner Bath: Designed to nest neatly into either the left or right corner of your bathroom, these baths maximise floor space while providing generous soaking depth. Ideal for asymmetric layouts or when you need to free up wall space for vanities, storage, or towel rails.
Styles & Profiles
- Flat-Edge Profile: Clean, squared lines for a strong visual presence that aligns beautifully with large-format tiles and floating vanities.
- Slimline Rectangle: Refined proportions that reduce bulk without sacrificing depth, ideal for narrow bathrooms or wall-to-wall installations.
- Double-Ended Rectangle: Sloped on both sides, perfect for reclining from either end and well-suited to shared use.
Materials & Finishes
Solid Surface (Cast Stone): Luxurious matte finish and superior heat retention make this ideal for extended soaking. Its dense feel enhances the bath's sculptural form.
Gloss White Acrylic: Lightweight and easy to install, especially in family bathrooms or multi-storey builds. White baths offer a reflective surface that helps open up smaller rooms.
Coordination & Accessories
-
Wall-Mounted Mixers: Align perfectly with the flat rim and right-angled sides of a rectangular bath.
-
Over-Bath Showers: Ideal for inset or back-to-wall models, try adding a hand shower or rain head for daily flexibility.
-
Bathroom Shelves or Niches: Continue the linear design language with rectangular wall cutouts or timber shelves.
-
Towel Rails: Mount parallel to the tub's long edge for a visually cohesive, functional setup.
