Futura FS 503 Undermount Series Kitchen Sink is a designer single-bowl kitchen sink engineered specifically for under-mount installation beneath premium countertops – granite, quartz, marble, and solid surface materials where a seamless, rimless aesthetic is the design intent. Measuring 29 x 16 x 9 inches and manufactured from thick-gauge High Grade SS 304 (18/8), the FS 503 is designed to sit flush below the countertop surface with no visible steel rim on the counter face, allowing water, food scraps, and debris to be wiped directly from the counter into the basin – eliminating the grime-collecting crevice that forms at the junction between a top-mount rim and the countertop surface in conventional sink installations.
The 9-inch basin depth provides high-capacity washing volume for large pressure cookers, deep pans, and stacked dishware while containing water splash-back effectively even under high-flow faucet use. The premium satin (brushed) finish delivers a professional, non-reflective surface that handles the visible wear of daily cooking and washing better than mirror-polished alternatives – fine scratches blend into the brushed grain and minor water marks are far less apparent. High-density sound-deadening pads on the underside absorb the clatter of dishes, cutlery, and running water, producing a noticeably quieter sink experience in open-plan kitchen and living spaces. Because the sink sits below counter level rather than on top of it, the full 29-inch width of counter above the sink cavity is available as usable workspace – no rim lip reduces the effective counter surface adjacent to the sink.
Key Features
Seamless Under-mount Design: No visible rim on the countertop surface – the sink sits fully below the stone or quartz slab, creating a clean architectural transition from counter to basin that is the defining characteristic of luxury kitchen fitouts.
Superior Counter Hygiene: Eliminates the crevice between sink rim and counter where food residue, water, and mold accumulate in top-mount installations – the full counter surface wipes clean directly into the basin with a single stroke.
9-Inch Basin Depth: Deep enough to fully accommodate large Indian pressure cookers, kadhais, and stacked dishware, while containing water splash-back during high-pressure rinsing – and deep enough to keep a pile of dirty dishes below the counter sightline.
High Grade SS 304 (18/8): 18% chromium, 8% nickel alloy with superior corrosion and chemical resistance – the correct specification for a kitchen sink exposed daily to food acids, salt water, and cleaning detergents in a heavy-use cooking environment.
High-Density Sound-Deadening Pads: Underside coating significantly reduces operational noise from running water, dish contact, and drainage – produces a measurably quieter kitchen environment compared to unpadded stainless sinks.

Installation Guidelines
Step-by-Step Installation
Confirm mounting style: The FS 503 is designed for under-mount installation on stone, quartz, or solid surface countertops. Flush or inset mounting can be done by a specialist installer – not recommended for laminate or wooden countertops where water ingress at the exposed edge is a long-term risk.
Professional countertop cutout: The cutout must be precisely sized to the sink template for the correct overhang or flush fit – professional stone cutting equipment is required for granite and quartz. Do not attempt freehand cutting on stone countertops.
Verify cabinet width: Ensure the base cabinet is wide enough to accommodate the 29-inch sink body plus the under-mount bracket clearance on each side – confirm minimum cabinet width with your installer before cutting.
Apply sealant: Apply a continuous bead of industrial-grade silicone sealant between the sink rim and the underside of the stone countertop – this creates the structural adhesive bond and the watertight seal simultaneously for an under-mount installation.
Secure with under-mount brackets: Install the provided heavy-duty under-mount clips to the underside of the countertop to carry the weight of the sink – allow the silicone to cure fully before removing any temporary support and loading the sink with water.
Recommended Applications
Where the Futura FS 503 fits best
Luxury Stone and Quartz Countertop Kitchens: The ideal companion for granite, quartz, marble, and solid surface countertops where a seamless, rimless sink integration is the design requirement – the under-mount installation is the standard for premium kitchen fitouts in this category.
Minimalist and Contemporary Kitchen Designs: For homeowners seeking a clean, uninterrupted counter surface without a visible steel rim – the FS 503 disappears below the countertop, letting the stone surface take visual prominence.
High-Hygiene Kitchen Environments: Eliminates the rim-to-counter crevice where food residue, standing water, and mold accumulate in top-mount sinks – the entire counter surface wipes directly into the basin.
Primary Prep and Wash Station: The 29 x 16 inch basin and 9-inch depth provide a generous single-bowl workspace suited to both vegetable preparation and the washing of large Indian cookware – pressure cookers, kadhais, and deep pans.
Premium Interior and Architectural Kitchen Projects: Specified by interior designers and architects for luxury residential projects where the kitchen sink is part of the overall design language rather than a utilitarian afterthought.
