What Makes One Kitchen Remodel Cost More Than Another

Homeowners usually ask what a kitchen costs. The more useful question is what makes one kitchen cost more than the one next door, because that is the part you control.

Moving plumbing is the biggest single decision

Keeping the sink and the range roughly where they are keeps a kitchen in the straightforward category. Moving them is what changes the project.

On a slab-on-grade house, which is most of Southern California's postwar housing, relocating a drain means cutting concrete, running new pipe, and repouring. In tract stock from the 1990s and 2000s the slab may be post-tensioned, which means it has steel cables in tension running through it. Those have to be located and avoided, and striking one turns into a repair project of its own.

If you have a raised foundation with a crawlspace, moving plumbing is considerably easier. Find out which you have before you fall in love with a layout.

Cabinetry is where the money and the calendar both go

Cabinets are usually the largest line item in a kitchen, and they are also the longest lead time. Stock cabinetry is quickest and cheapest. Semi-custom gives you sizing flexibility. Full custom fits an irregular space exactly and costs accordingly.

The scheduling consequence matters as much as the price. Cabinets ordered late become the reason a finished kitchen sits unusable, because countertops cannot be templated until the boxes are set. When we sequence a kitchen, the cabinet order goes in early for exactly this reason.

What is behind the wall

Opening up a kitchen in an older house tends to surface the same short list:

• An electrical panel without capacity for modern kitchen circuits
• Ungrounded two-wire branch circuits that need replacing once the wall is open
• Galvanized or cast iron supply and waste lines at the end of their life
• No blocking where you want to hang anything heavy

None of these are surprises to anyone who has done this work. They should be discussed as possibilities before demolition, not presented as change orders afterward. Ask any contractor how they handle conditions discovered after opening a wall, and get that answer in the contract.

Taking out a wall

Whether the wall between the kitchen and the next room is load bearing changes the scope substantially. Removing a bearing wall means a beam, posts down to adequate footings, and engineering. In tract housing with a truss roof there is often a girder truss over exactly the wall people want gone.

There is also usually a dropped soffit above the cabinets carrying the original branch ducting and recessed cans. Whether that ducting can be rerouted is what decides if the ceiling can actually go flat, and that question is worth answering during design rather than during framing.

Ventilation is not a finish selection

Hood capacity is a real engineering number tied to your range. A high-output range needs a hood that can move the air, and a hood that moves that much air needs makeup air to replace it. The duct run to the exterior wall, its length, and the number of turns all matter. This gets treated as a style choice far too often and then underperforms for the life of the kitchen.

Where you can save without regretting it

Keep the layout. Choose stock or semi-custom cabinetry in a good finish rather than custom in a cheap one. Spend on the things that are expensive to change later, meaning anything inside a wall or under the slab, and economize on the things you can swap in ten years, like light fixtures and hardware.

The reverse of that is the common regret: beautiful finishes over old wiring and undersized ventilation.

Reading your quotes

Ask each contractor for a written line-item scope rather than one number. You want to see cabinetry, countertops, appliances, electrical, plumbing, and labor broken out, plus a stated allowance for anything not yet selected. Two quotes that look far apart usually turn out to be different assumptions about allowances and about what is behind the walls.
