Buying Guide: What To Consider When Choosing an Undermount Double Bowl
- Material and gauge: Heavier gauges (18-gauge) resist dents and stains; lighter gauges (20- or 16-gauge) may be more budget-friendly but less sturdy.
- Bowl configuration: 50/50 bowls suit multitasking; offset or rear-set drains impact installation and countertop clearance.
- Installation type: Undermount provides a seamless look and easy countertop cleaning, but requires precise cutouts and professional sealing.
- Finish and maintenance: Wear-resistant finishes help keep sinks looking new; brushed finishes conceal fingerprints and water spots.
- Cabinet compatibility: Ensure cabinet width and minimum size align with external sink dimensions and drain placement.
- Drain and hardware: Some kits include drains and installation hardware; consider whether you need rear-set or center-set drains.
- Budget vs durability: 18-gauge sinks offer robust durability; 16-gauge models push the upper price but long-term value.
