Rough Plumbing Rough-In for a Bathroom Single-to-Double Sink Upgrade

Most people think a bathroom remodel is all about tile, fixtures, and paint. And sure, that stuff matters. But the work that actually determines whether your remodel holds up long-term happens behind the wall - before any of that even starts.

Here's what we were working with: a single-sink bathroom that the homeowner wanted to convert to a double sink. Simple enough on the surface. But making that happen the right way means rerouting supply lines, adding drain connections, and getting everything positioned correctly so the finished rough-in lines up perfectly with where the new vanity will sit. Copper supply lines for the hot and cold runs, ABS drain and vent work tied in cleanly - this is the kind of setup that gives you a reliable, leak-free result once the walls close back up.

Getting this stage right is everything. If the rough-in is sloppy - wrong spacing, undersized drain, poor venting - you end up with problems that are a nightmare to fix after the drywall goes back up. We see it all the time on jobs where someone tried to cut corners early. The goal here is always to give the next phases of the remodel a clean, solid foundation to build on.

A double-sink setup genuinely changes how a bathroom functions day-to-day. Less congestion during morning routines, more counter space, better use of the wall. It's one of those upgrades that feels like a bigger deal than it looks on paper - and it starts with getting the plumbing dialed in exactly right from the beginning.

Whether you're planning a full bathroom overhaul or just expanding what you already have, the rough plumbing phase is where we earn our keep. We handle everything from pipe repair and repiping to full rough-in work like this so the rest of your remodel goes smoothly.
