Call (512) 555-0147Plumbing for a kitchen that is being remodeled: island sinks with no wall to hide a drain in, appliance lines that multiply, and how far a sink can move before the floor has to open.
01Kitchen remodels
Each of these changes how much new line the remodel needs, and how early it has to be planned.
An island sink has no wall behind it to hide a drain and vent, so both have to run under the floor to reach the rest of the house’s drain and vent system, which is more work than a sink against a wall needs.
A dishwasher, an ice maker, a filtered tap and sometimes a gas-burning range each need their own supply run to roughly the same area, so a kitchen gaining appliances is gaining connections to feed them, not just outlets.
A short move along the same wall usually reaches the existing drain and supply lines. Moving the sink to a different wall, or into an island, goes past that and means opening the floor to run new lines.
02The sink's location
Both are common in a kitchen remodel, and they ask very different amounts of a drain and a vent.
The drain and vent run into the wall behind the sink and connect to the rest of the house's plumbing close by. It is the more straightforward of the two, and usually the more direct path if the sink is staying near where it already sits.
With no wall to run into, the drain and vent go down through the floor instead, often traveling some distance beneath it to reach the rest of the plumbing. It is more work, and it needs deciding early, before the floor is finished.

03Appliance lines
A modern kitchen asks for more individual supply runs than it used to. These are the ones that add up.
A supply line, a drain connection and usually an air gap or a high loop all run to wherever the dishwasher sits, tied into the same connection the disposal uses beneath the sink.
A dedicated supply line runs to wherever the refrigerator sits, usually through the wall or floor, with its own shutoff so it can be worked on without affecting the rest of the kitchen's plumbing.
A separate small supply line runs to a filtered or instant-hot tap at the sink, in addition to the sink's own hot and cold lines, usually connected to a small filter housed under the cabinet.
Where a range burns gas instead of running on electricity, the gas supply has to be sized and run to reach it, connected the same way any other gas appliance is, and kept entirely separate from the kitchen's water lines.
04The layout
A kitchen layout decides where every drain, vent and supply line in the room has to go, which makes it a plumbing decision as much as a design one. Moving the sink, adding an island, or adding an appliance that was not in the kitchen before all change where those lines run, and how far they have to travel to reach the rest of the house’s plumbing.
Settling the layout with the plumbing in mind, before anything is roughed in, is what keeps the rest of the remodel on the plan it started with. A layout finalized without checking what the floor and the walls can actually carry is one of the more common reasons a kitchen’s plumbing plan changes once the work is already underway.
05Questions
Usually, yes, but it takes more plumbing than a sink against a wall. With no wall behind it to hide a drain and vent, both have to run beneath the floor to reach the rest of the house’s plumbing, so an island sink is planned early rather than added at the end.
More than the last kitchen, in most remodels. A dishwasher, an ice maker, a filtered tap at the sink and, for some ranges, the gas supply each need their own run, so a kitchen gaining appliances is also gaining plumbing connections, not just outlets.
A short shift along the same wall or run of cabinets usually reaches the existing lines without much extra work. Moving it to a different wall, or into an island, goes past that and calls for new drain, vent and supply runs beneath the floor.
Before the layout is finished, not after. Where the sink and the appliances sit decides where the drain, vent and supply lines have to run, and settling that early is what keeps the plumbing plan from changing once the work is already underway.
