KINGWONG 18.3" Undermount Bathroom Sink – Ceramic Porcelain Excellence for Your Bathroom Remodel Upgrade your master bathroom, powder room, or guest bath with the KINGWONG rectangular undermount bathroom sink. We designed this under counter basin sink to solve the three biggest frustrations homeowners face: difficult cleaning, stained or faded porcelain, and concerns about cracking over time. Superior Material – Vitreous China That Lasts Unlike cheap earthenware, our white ceramic sink is high-temperature kiln-fired to achieve a high degree of porcelain vitrification. The result is a non-porous, ultra-smooth surface that resists absorption, so water beads up and rolls off. This same dense glaze provides excellent acid and alkali resistance, meaning harsh bathroom cleaners won't dull or etch the finish. Your sink stays brilliant white and does not fade or change color—even after years of daily use. Engineered for Thermal Shock Resistance Have you ever worried about pouring hot water down a cold sink? Our ceramic porcelain undermount sink is fired at extreme temperatures, giving it exceptional resistance to sudden temperature changes. Whether you rinse hot styling tools or drain hot cleaning water, the basin will not crack from thermal shock. Effortless Cleaning, Every Day The smooth, glossy finish of this under mount sink means dirt, soap scum, and hard water stains have nowhere to hide. A quick wipe with a soft cloth restores its like-new shine. And because it installs as an undermounted vanity sink, you can sweep countertop debris directly into the basin—no raised rim to trap grime. Important Installation Note This sink comes without pre-drilled faucet holes, making it ideal for wall-mounted faucets or countertop-mounted faucets. For a secure, long-lasting installation, we recommend using a high-quality silicone sealant combined with mechanical mounting clips (not included) to prevent sagging or leakage over time.
