Our Fullerton clients appreciate the added hygiene and the sophisticated, custom look that a milled drainboard provides to their stone surfaces.

Can a drainboard be added to an existing countertop already installed in a home?

Milling a drainboard requires the use of heavy industrial CNC machinery and a constant flow of water for cooling, which makes it a shop-only process. Therefore, the drainboard must be fabricated during the initial production of the countertop before it is delivered to your Fullerton residence. We cannot retroactively mill drainage channels into a countertop that has already been installed in a kitchen.

Is it difficult to keep the milled grooves of a drainboard clean?

The grooves are polished to a smooth finish during fabrication, which prevents soap scum and mineral deposits from adhering to the stone. Regular wiping with a soft cloth and a pH-neutral stone cleaner is sufficient to keep the channels clear and functional. This design is inherently more hygienic than traditional racks because there are no hidden corners for mold or bacteria to grow.

Does milling grooves into the stone make the countertop more fragile?

We use advanced structural reinforcement techniques, such as rodding, to ensure the slab maintains its full strength despite the reduced thickness in the grooved areas. The depth of the channels is carefully calculated based on the specific material's flexural strength to prevent any risk of cracking. This engineering ensures that your Fullerton kitchen countertop remains durable enough for heavy daily use.

Are integrated drainboards compatible with both undermount and drop-in sinks?

Integrated drainboards are specifically designed for use with undermount sinks to allow water to flow directly over the stone edge and into the basin. This configuration creates a seamless, flush transition that is both aesthetically pleasing and highly functional for water management.
