American Standard Studio S Single Hole Single-Handle Vessel Sink Faucet 1.2 gpm/4.5 L/min With Lever Handle - AMS-7105172

The Studio S vessel faucet is built for a single-hole deck mount, so the sink or countertop needs one hole only. It is a vessel-height faucet, meaning the spout is tall enough to clear the rim of an above-counter basin. If your basin is a drop-in or undermount with a standard-height deck, a regular single-hole lavatory faucet is the better choice; the tall vessel body would overshoot the bowl.

A grid drain is included, along with flexible braided stainless steel supply hoses with compression connectors. That covers the supply side and the drain body, so the only thing you would typically add is the P-trap and any escutcheon your exposed-trap install calls for. Note the grid drain is non-closing, so this is not the faucet to pick if the owner wants a pop-up stopper.

It runs at 1.2 gpm (4.5 L/min) and is WaterSense certified. That matters on LEED and green-building projects and in jurisdictions like California that cap lavatory faucets below the federal 2.2 gpm. For a hotel or multi-family rollout, the 1.2 gpm rating is the number the spec reviewer is looking for.

It has an adjustable hot limit safety stop, which lets you cap how far the handle rotates toward hot at the point of install. That is the feature facilities people look for in schools, senior housing, and healthcare washrooms where tempering at the fixture is part of the scald-prevention plan. It is a single-handle mixing faucet, not a thermostatic mixing valve, so it does not replace a code-required point-of-use mixing valve where one is specified.

Two: matte black (part number 7105172.243) and brushed nickel (7105172.295). If you are standardizing a floor of units, order by that suffix, since the base 7105172 number is shared across both. Matte black tends to pair with black grid drains and traps on exposed-trap vessel installs, so plan the trap finish alongside it.

Yes, in most retrofits. The faucet ships with flexible braided stainless steel supply hoses that terminate in compression connectors, so they thread onto standard 3/8 inch compression angle stops without adapters. If your stops are an older or non-standard outlet, you would need a matching adapter or a new stop.

Metal lever handle. That is the detail that matters for rental and hospitality work, where plastic handles are the first thing to crack or spin. A lever, rather than a knob, is also the style most accessibility guidelines favor because it can be operated without tight grasping or twisting.
