MSI Porcelain Flat-Bottom Rectangular Undermount Bathroom Sink 20"
$84.21
Unit price perA wide white porcelain undermount basin with a flat-bottom rectangular bowl, mounted below the counter for a seamless vanity edge. The near-level basin floor and generous 19-3/4" x 15-3/4" footprint give you a roomy, easy-to-use wash area, while three overflow holes add extra spill protection. Glazed porcelain keeps cleanup simple.
Features
- Flat-bottom basin — a near-level bowl floor holds soap, brushes and a wash cup without them sliding to the drain.
- Triple overflow — three overflow holes provide extra protection against overfilling.
- Undermount installation — mounts beneath the counter for a clean, wipeable edge.
- Glazed porcelain — non-porous surface resists staining, odors and daily wear.
- Wide, shallow profile — 7-1/8" depth over a 19-3/4" x 15-3/4" footprint suits full-size vanities.
- Standard 1-11/16" drain opening — pairs with common bathroom pop-up drains.
