American Standard 0495300 Ovalyn Undermount 19 Sink Cutout
Description
The American Standard 0495300 Ovalyn is a contemporary oval undermount bathroom sink designed for elegant residential and commercial vanity installations. This vitreous china sink measures 17.125" x 14.125" overall with a graceful oval bowl that provides 15.0625" x 12.0625" of usable space at 5.5" depth. Our production-ready DXF template includes four installation variants optimized for different fabrication requirements: no reveal for seamless flush mounting, 1/8" reveal for standard undermount installations with clean visual definition, 1/2" overhang for traditional bathroom aesthetics, and drop-in configuration for alternative mounting scenarios. The Ovalyn collection is renowned for its timeless oval profile that complements both contemporary and traditional bathroom designs. Vitreous china construction delivers a durable, non-porous surface that resists staining, maintains its glossy finish, and cleans effortlessly. The oval shape provides superior bowl capacity compared to rectangular sinks of similar dimensions, while the smooth curves eliminate hard-to-clean corners. This model features a front overflow for proper drainage and ADA compliance considerations. The sink requires a minimum 24" cabinet width and ships with an undercounter mounting kit and installation template. Our enhanced DXF template provides CNC-level precision for professional fabrication workflows, ensuring consistent results across multiple installations.

Installation Overview
Installing the American Standard 0495300 Ovalyn requires understanding the unique considerations of oval sink mounting in countertop materials. Begin by verifying cabinet compatibility - minimum 24" width with adequate depth for undermount clearance and plumbing. Position the template on the vanity top underside with at least 2.5" clearance from front edge and 3" from side edges to maintain structural integrity. The oval shape means there are no true corner stress points, but the transition from major to minor axis creates areas of increased curvature that require smooth, continuous cutting. For standard undermount installations, use the 1/8" reveal variant which reduces the cutout dimensions by 0.25" on all axes, creating a uniform lip around the oval perimeter. This reveal provides visual definition and installation tolerance while concealing minor cutting variations. Before cutting, mark the front-to-back centerline on both the template and vanity top to ensure proper alignment. The Ovalyn is designed for centered installation in most applications, though offset positioning may be specified for specific faucet or vanity configurations. After CNC cutting or template routing, test-fit the sink and verify that the overflow opening positions correctly (typically at the front-center of the bowl). Apply a continuous bead of 100% silicone sealant around the entire oval perimeter, maintaining consistent bead width of approximately 1/4". Because vitreous china is fragile, never rely on mechanical clips alone for support. Instead, supplement the silicone bond with support blocks or continuous rails beneath the sink body, bonded to the countertop underside with construction adhesive or epoxy. Position the sink carefully, ensuring centered alignment and proper front orientation, then apply even pressure around the perimeter to compress the silicone. Install support blocks at 4-6 locations around the oval, distributing weight evenly. Allow silicone to cure for minimum 48 hours before connecting plumbing or placing any stress on the installation.
CNC Cutting Notes
Cutting oval shapes requires different CAM programming considerations compared to rectangular sinks. The Ovalyn template defines a true ellipse with major axis approximately 15.0625" and minor axis approximately 12.0625" for the no-reveal variant. When importing the DXF to your CAM software, verify that the elliptical profile imports as a smooth curve rather than segmented polyline, as this affects edge quality and cutting efficiency. Use continuous arc interpolation if your controller supports it, or increase polyline segment density to minimize faceting. For natural stone vanity tops, use a 3/8" or 1/2" diamond router bit with continuous water cooling. Because ovals have no corners, you can maintain consistent feed rates throughout the cut - aim for 60-80 IPM for granite and 80-100 IPM for engineered quartz. The smooth curve means no relief cuts or corner slowdowns are required, making oval cutouts faster to machine than rectangular profiles. Program the toolpath to start and end at the back center of the oval (furthest point from the front edge) to hide any slight overlap or step in the finished edge. For the 1/8" reveal variant, the cutout is offset inward by 0.125" from the bowl rim on all sides, creating a uniform lip. Verify that your CAM software applies this offset correctly to the elliptical profile, maintaining the oval shape rather than creating irregular curves. After cutting, inspect the edge carefully for any segmentation or faceting, particularly at the major and minor axis points where curvature is maximum. The edge should be perfectly smooth around the entire perimeter. Use diamond hand pads to remove any roughness or tooling marks before installation.
Material Compatibility
The Ovalyn template is compatible with granite, engineered quartz, quartzite, marble, and solid surface vanity materials. The oval cutout shape actually provides some structural advantages compared to rectangular cutouts of similar size, as the smooth curves distribute stress more evenly without corner concentration points. For granite vanities, 2cm thickness is standard for bathroom applications and is adequate for this cutout size (approximately 15" x 12" for the 1/8" reveal variant). However, 3cm provides superior strength and a more substantial appearance if the design budget allows. Maintain minimum 2.5" edge clearance on all sides for 2cm material, or 2" for 3cm material. Engineered quartz is increasingly popular for bathroom vanities due to its non-porous surface, consistent coloring, and resistance to staining. Quartz requires no sealing and performs exceptionally well in humid bathroom environments. The oval shape cuts cleanly in quartz with excellent edge quality. Marble is suitable for bathroom vanity applications where acid exposure is minimal, though it requires regular sealing to prevent water staining. The Ovalyn's oval profile is particularly attractive in marble, as the smooth curves showcase the stone's veining patterns. Solid surface materials like Corian are excellent choices for undermount bathroom sinks. The oval can be cut with carbide router bits and bonded seamlessly to the vitreous china using manufacturer-approved acrylic adhesives. For thin porcelain slabs (6-12mm), this cutout requires careful reinforcement planning, as removing a 15" x 12" oval creates significant material loss. Install steel mesh or frame reinforcement spanning the cabinet perimeter if using ultra-thin materials.
Where to Buy

The sink ships with an undercounter mounting kit including template, mounting hardware, and installation instructions. Our DXF files provide enhanced precision beyond the paper template for CNC fabrication workflows. Lead times are generally favorable as this is a stocked item at most major distributors - expect 1-2 week availability in most regions. For specification verification and technical support, contact American Standard customer service at 800-215-5130 or visit americanstandard-us.com. PDF specification sheets are available from major retailers and the manufacturer website. When specifying for clients, verify faucet requirements (this undermount model uses deck-mount faucets installed in the countertop) and confirm that the oval profile fits the client's aesthetic preferences. The Ovalyn's classic oval shape has remained popular for over a decade, making it a safe specification choice for both contemporary and traditional bathroom designs.
