Piano 304-Grade Smart Kitchen Sink with Waterfall (30 x 18 x 9 Inches)

A Smart Kitchen Sink With Piano Keys for Every Outlet

The Piano puts five outlets on one deck: a pull-out faucet, a big waterfall, a small waterfall, a glass rinser and an RO tap. Each has its own Piano Key: press to turn it on, press again to turn it off. Several outlets can run together; the flow is lower when they do. One knob sets the water from cold to hot for the pull-out, both waterfalls and the glass rinser. See all our kitchen sinks.

Self-Powered Smart Display

A small dynamo inside the panel turns water flow into power, so the display needs no battery and no electrical point. It shows the water temperature in °C and the total running time while water flows through the pull-out faucet, the waterfalls or the glass rinser. It is not thermostatic: you set the temperature with the knob and read it on the display.

Twin Waterfall, Hot or Cold

The big waterfall gives a shower-style flow; the small waterfall gives a smooth sheet of water. Both take hot or cold water from the same knob. Hot water up to 60°C from any geyser.

3-Mode Spray Head Pull-Out Faucet

The pull-out faucet has a 304-Grade stainless steel body, a 35 mm ceramic cartridge and a 1.5 m nylon hose with a counterweight that draws the head back. On the removable ABS head, the round button gives Sector flow and the two-way switch gives Spray (top) or Stream (bottom). It stands 385 mm above the countertop with a 335 mm reach.

Built-in Glass Rinser and Dedicated RO Tap

Place a glass or cup upside down on the rinser, press its key to rinse, and press the key again to stop. The Dedicated RO Tap is fed straight from your RO purifier and switched on from the panel; it is tested to withstand 500,000 operations. The RO connector is in the box.

Twist-to-Drain Knob and Top-Fill Soap Dispenser

Turn the drain knob on the panel clockwise to drain the sink and anti-clockwise to hold water. The Top-Fill Soap Dispenser holds 300 ml and refills from the top.

A Handmade 304-Grade Stainless Steel Bowl

The bowl is handmade from 304-Grade stainless steel, with Handcrafted easy-clean corners. Self-healing chromium shield: the 18% chromium in 304-Grade steel forms an invisible layer that protects against rust and re-forms if scratched. Silent Base: rubber pads under the bowl help reduce noise from pots and running water. The bowl is PVD Matt Black, colour bonded to the steel in a vacuum chamber, not painted on, and a Nano coating resists moisture and rust. The panel, pull-out faucet, RO tap, soap dispenser and baskets are Matt Black too.

All-Steel Prep Kit

A 304-Grade steel chopping board, strainer basket and vegetable basket come in the box.

Drop-in Fit for a 28 x 16.5 Inches Cutout

The Piano is a drop-in (top-mount) sink: it rests on its rim in a 711 x 419 mm (28 x 16.5 Inches) countertop cutout, with no clips, screws or silicone. Keep at least 65 mm between the back of the cutout and the wall, and 430 mm of space under the sink. Undermount installation is not recommended. The sink needs about 40 PSI (2.8 bar) at its water inlet. With a high overhead tank (about four floors up) and ¾ Inch pipes with few bends, no pump is needed. Otherwise fit a 1.5 HP pump with a 24-litre tank. We recommend a plumber, or book Home Installation, available in serviceable cities: sink bowl ₹1,599 and control panel ₹1,999 (T&C).
