You\u2019re at the point where you realize that you don\u2019t need two sinks in your bathroom. Maybe you\u2019re the only person who uses this<\/span> bathroom, or<\/span> you\u2019re just in harmony with whoever you share the bathroom sink <\/span>with, and only<\/span> one sink is needed.\u00a0<\/span><\/p>\n

You want to downsize, but you\u2019re not sure that it\u2019s possible. We\u2019re here to tell you that it is. <\/span>Changing a double sink to a single sink<\/span> is possible without a total plumbing overhaul.\u00a0<\/span><\/p>\n

Can You Change a Double Sink to a Single Sink?<\/h2>\n

Yes, it is entirely possible and often recommended for homeowners looking to reclaim counter space. To change plumbing from a double sink to a single, a professional typically merges the two existing drainage lines into a centered P-trap and properly caps the unused water supply lines.

This means they end up going into the same drainage pipe. In other circumstances, each sink can have its own drainage system. <\/span>If this is the case for you, our professionals can perform the necessary work to merge your internal plumbing before they convert your double-sink setup into a single one.<\/span>\u00a0<\/span><\/p>\n
