Karran acrylic double bowl sink is a 31-1/2 inch wide, double equal bowl kitchen sink made for undermount installation, giving installers a defined product format for standard kitchen base layouts. The sink is manufactured from an ultra high density, 100% pure acrylic resin, so the material delivers a consistent surface across both bowls for a uniform appearance in the cabinet run. It is formed by thermoforming using heat and vacuum, which shapes the acrylic accurately to the bowl design for predictable fit against the countertop cutout. The underside is reinforced with an FRP backing, supporting the acrylic body so the sink structure resists flex under normal use. A 1-1/4 inch by 3/4 inch machined resin matrix rim provides a precise mounting surface, which matters when aligning the sink edge to solid surface, laminate or stone.
This acrylic kitchen sink requires undermount installation, so it installs from below the countertop and relies on the machined resin matrix rim for support and bonding. It may not be top mounted, keeping the rim hidden and leaving the countertop edge as the working surface. The sink can only be installed in new countertops, not in existing countertops with an existing sink cutout, which aligns it with new fabrication or full replacement projects. It may be bonded seamlessly in solid surface and laminate, allowing fabricators to build an integrated sink-counter unit. The sink may be undermounted to all stone products, with a 1/8 inch overhang recommended, giving stone shops a clear edge detail target when finishing cutouts.
This double equal bowl kitchen sink fits projects where two equal work zones are preferred at the main kitchen sink location, supporting tasks on either side without changing bowl volume. The bisque color option allows the sink to coordinate with bisque-toned solid surface, laminate or stone, giving designers another neutral color choice. Its ability to be bonded seamlessly in solid surface and laminate means shops using those materials can integrate the sink visually and mechanically into the deck. The capability to be undermounted to all stone products, with a 1/8 inch overhang recommended, suits granite, quartz and similar stone fabrication workflows that rely on precise edge profiles. All external dimensions are approximate to 1/4 inch, so fabricators can allow reasonable tolerances when planning cabinet and countertop layouts.
The ultra high density, 100% pure acrylic resin construction is heat, scratch and chip resistant, contributing to a sink surface that stands up to typical kitchen use and helps reduce premature replacement. The material is stain and thermal shock proof, which supports long-term appearance when exposed to common household liquids and temperature changes. A completely non-porous structure means the sink surface does not absorb moisture, aiding cleanability and helping maintain a consistent look in service. The FRP backing on the underside stabilizes the sink during bonding and clamping, reducing the likelihood of distortion that could affect seam quality. Karran provides digital templates for CNC machines at www.karran.com, which helps shops integrate the sink into automated routing workflows and reduce manual layout time. A 25 years Limited Warranty against manufacturer's defects backs the product, adding manufacturer support over an extended service period.
The Karran A-355-BISQUE sink has double equal bowls, so both sides share the same size, which simplifies faucet centering and workflow planning at the cabinet.
The sink is manufactured from ultra high density, 100% pure acrylic resin, thermoformed with heat and vacuum, then reinforced underneath with FRP to support structural stability in use.
The sink is designed for undermount installation only and may not be top mounted, so it is used from below the countertop with the rim concealed.
The sink can be bonded seamlessly in solid surface and laminate and may be undermounted to all stone products, giving flexibility across common countertop materials.
When undermounting to stone products, a 1/8 inch overhang is recommended, which guides fabricators on the exposed stone edge relative to the sink bowl.
The sink has a 25 years Limited Warranty against manufacturer's defects, providing long-term manufacturer backing for the acrylic construction and design.
The Karran Acrylic Series 31-1/2 inch wide bisque undermount double bowl sink combines ultra high density acrylic resin, FRP backing and a machined resin matrix rim to support fabrication-centric installations. Its ability to bond seamlessly in solid surface and laminate, and to undermount to stone with a defined 1/8 inch overhang, fits common shop workflows. For projects centered on new countertops where a double equal bowl layout and non-porous bisque finish are desired, this sink offers a clear, specification-driven option ready for integration into your next kitchen run.
