Does whole-house customization charge extra for sink cutouts?

Whether sink cutouts cost extra depends mainly on the worktop material and the cutout method. Quartz and sintered stone cutouts require on-site processing and are usually charged by the actual sink dimensions; undermount sinks also require reinforcement and edge polishing, so the cost is higher. During measurement we confirm the sink and water supply/drainage positions, then re-measure after the plumbing and electrical positioning is completed to avoid cutout deviation. We serve Beijing, Tianjin, Langfang, Baoding, and Xiong'an New Area, and you can book a visit to the Gaobeidian factory to see cutting, edge banding, side drilling, and other processes. Cutout fees are confirmed separately based on on-site conditions and are not included in the cabinet body quote.
