Installation Overview
Installing the Kohler Sensate touchless faucet requires one precisely positioned 1.5-inch diameter hole drilled perpendicular through the countertop surface. This is larger than the standard 1.375-inch hole used for mechanical faucets, so verify you're using the correct template before cutting. Position the hole center at least 2.5 inches from the sink rim to provide adequate clearance for the faucet base, sensor housing, and mounting hardware access from below. The Sensate faucet requires an unswitched 120V AC power outlet located below the sink and within 5 feet of the control box, so coordinate with the electrician during the rough-in phase to ensure power availability. For standard undermount sink installations, position the faucet hole on the deck between the sink and the front edge of the countertop. The Sensate features a 15-9/16 inch total height and 8-7/16 inch spout reach, making it suitable for sinks up to 24 inches front-to-back. When installing near a backsplash, maintain at least 3 inches clearance from the wall to allow for full spout swivel and handle operation. The hole must be drilled clean through the countertop material with smooth, chip-free edges on both top and bottom surfaces. Pay special attention to edge quality, as rough or chipped holes can interfere with the electronic components and sensor performance. The Sensate installation includes a control box that mounts below the sink, typically to the cabinet side wall, and connects to the faucet body via data and power cables. Ensure adequate space below the deck for the control box and AC adapter, and verify that the sink bowl configuration doesn't interfere with the required electrical connections. The faucet includes an optional manual override mode in case of sensor malfunction or power loss, activated by a button on the spout body.
CNC Cutting Notes
For optimal results when programming this template for CNC fabrication, create a tool path for a single 1.5-inch diameter through-hole positioned at the exact coordinates specified in the DXF file. This non-standard hole size requires careful bit selection—use a precision 1.5-inch diamond core bit for engineered quartz and solid surface materials, or a 1.625-inch bit for natural stone materials to achieve a clean 1.5-inch finished hole accounting for material variance. The larger hole diameter compared to standard faucet installations means increased cutting time and greater stress on the material, so verify adequate edge distance on all sides—maintain at least 2.5 inches from the hole edge to any other cutout or countertop edge. Set your CNC approach angle to exactly 90 degrees relative to the countertop surface, as the electronic sensor components require precise vertical alignment for proper function. For granite and quartzite, program spindle speeds between 2,800-3,500 RPM with feed rates of 4-6 inches per minute, using continuous wet cutting to manage heat buildup and prevent thermal cracking. When cutting engineered quartz materials, reduce spindle speed to 2,000-2,800 RPM to prevent resin melting around the hole edge, which could interfere with the faucet's electronic seals and gaskets. Ensure adequate coolant flow to flush resin dust and stone particles from the cutting area, as debris buildup can cause rough edges that affect installation quality. For ultra-compact surfaces like Dekton and Neolith, use diamond core bits specifically rated for porcelain cutting and reduce feed rates to 2-4 inches per minute due to extreme material hardness. The Sensate faucet's tight tolerances mean the hole diameter must be accurate to within ±0.02 inches—any smaller and the faucet body won't fit through; any larger and the mounting escutcheon may not properly cover the hole edge. Always run a test hole on scrap material to verify the finished diameter meets specifications before cutting the final workpiece. For manual fabrication, use a variable-speed drill press with digital readout and secure the material firmly with clamps to prevent movement during drilling. The 1.5-inch hole requires more drilling force than standard faucet holes, so ensure your equipment can handle the increased load without deflection.
Material Compatibility
This Kohler Sensate touchless faucet template is compatible with all standard countertop materials, though the larger 1.5-inch hole diameter places slightly greater demands on material strength compared to standard faucet installations. Natural granite provides excellent structural support for the Sensate faucet's electronic components and heavier weight (the touchless mechanism adds approximately 1.5 pounds compared to mechanical faucets). The dense crystalline structure of granite easily accommodates the 1.5-inch hole without compromising countertop integrity, assuming minimum 3cm thickness and adequate edge distance. When working with granite slabs, inspect the area around the planned hole location for visible fissures, mineral inclusions, or areas of contrasting density that could cause chipping during the larger diameter drilling operation. Engineered quartz surfaces from Cambria, Caesarstone, Silestone, and other manufacturers are ideal for Sensate installations due to their uniform composition, consistent hardness, and excellent vibration dampening properties. The resin binder in quartz materials provides electrical insulation benefits for the faucet's electronic components, though the larger hole size means more resin exposure during cutting—use lower spindle speeds and adequate cooling to prevent resin burnout. Marble and other calcium-based natural stones work with this template, though fabricators should exercise caution when drilling the larger 1.5-inch hole in softer marble varieties like Carrara or Crema Marfil. Use sharp diamond bits, slower feed rates, and back the hole exit point with scrap material to prevent catastrophic chipping. Solid surface materials including Corian, Avonite, and LG Hi-Macs can accommodate the Sensate faucet, though the lightweight nature of solid surface may require additional backing support for the heavier touchless faucet assembly—consult with the solid surface manufacturer for reinforcement recommendations. For ultra-compact surfaces like Dekton, Neolith, and Lapitec, use only diamond core bits specifically rated for porcelain tile cutting, as the 1.5-inch diameter hole will wear standard stone bits very quickly on these extremely hard materials. The larger hole diameter means more time and tool wear, so factor this into your fabrication pricing. Avoid using this template for laminate countertops, as laminate materials cannot support the weight and mounting requirements of the Sensate touchless faucet system. All materials should be minimum 2cm thickness for quartz and solid surface or 3cm for natural stone to provide adequate structural support for the faucet assembly and electronic components.
Where to Buy
The Kohler Sensate touchless kitchen faucet (K-72218) is available through select distribution channels specializing in premium kitchen fixtures and smart home technology. For the most comprehensive product knowledge and installation support, work with Kohler Registered Showrooms in your market area. Showroom design consultants can demonstrate the Sensate's touchless operation, explain the KOHLER Konnect app functionality for voice control and custom settings, and help clients choose from available finishes including Polished Chrome (CP), Vibrant Stainless (VS), and Matte Black (BL). Registered showrooms also stock the optional AC power supply extension cable (K-1954357) needed for installations where the electrical outlet is more than 5 feet from the control box location. For trade pricing, establish accounts with premium plumbing distributors such as Ferguson Enterprises or specialized kitchen and bath suppliers that carry Kohler's electronic faucet line. Not all plumbing distributors stock the Sensate due to its advanced electronics and higher price point, so verify availability before promising delivery dates to clients. The Sensate typically requires 2-5 business days lead time for special order, even through major distributors. Online retailers including Build.com, eFaucets, and FaucetDirect offer competitive pricing on the Sensate with detailed specification sheets and installation videos. When purchasing online, verify that the retailer is an authorized Kohler dealer to ensure full manufacturer warranty coverage—some gray-market sellers offer discounted pricing but may not provide valid warranty support. The Sensate faucet is generally not stocked in big-box home improvement stores due to its professional-grade features and price point (typically $600-$800 retail depending on finish), though some Home Depot and Lowe's locations can special order the product with extended lead times. When specifying the Sensate for client projects, always order the faucet well in advance of the countertop installation date to account for potential delivery delays and to allow the client to inspect the product before installation. Include the required 120V electrical outlet in your scope discussions with the client, as many homeowners are unaware that touchless faucets need electrical power—coordinate with the electrician to ensure the outlet is installed during rough-in. Some fabricators partner with electricians to offer turnkey installation including the electrical work, markup the combined package 15-20%, and provide single-point warranty coverage for the client. The Sensate is covered by Kohler's limited lifetime warranty on the faucet body and finish, with one-year warranty coverage on the electronic components including the sensor, control box, and AC adapter.
