Most Rancho Murieta homeowners plan remodel projects one room at a time. The kitchen this year, the master bath next year, the secondary baths in three years. The logic feels sound: spread the cost, live with one disruption at a time, take it slowly.

The math usually does not support it. Doing the kitchen and bathrooms simultaneously under a single contractor, with a single permit application and mobilization, typically costs 15 to 25 percent less than the same scope done in separate projects. And the disruption, while more intense during the project, is concentrated rather than drawn out over several years.

Here is how the economics and sequencing actually work.

Where the Savings Come From

Single Permit Application

Sacramento County charges permit fees based on project valuation and scope. When you pull a separate permit for a kitchen remodel and another separate permit for a bathroom remodel, you pay two application fees, two plan check fees, and two inspection fees. A single combined permit for both scopes pays one set of fees. For a kitchen and two baths in Sacramento County’s unincorporated area, the permit fee difference clearly favors the combined permit.

Single Mobilization

Every time a contractor mobilizes for a project, there are real costs: equipment transport, subcontractor coordination, temporary protection of adjacent surfaces, material delivery, and crew setup. For plumbers and electricians especially, the hourly rate looks the same whether they are driving to a kitchen rough-in or a bathroom rough-in, but the mobilization cost is already paid once the truck is there. A combined project sequences the kitchen and bathroom rough-in on the same day or same week. Separate projects pay mobilization twice.

Material Efficiency

Tile, grout, lumber, and finish materials have minimum order quantities and delivery costs. When a kitchen and master bath use compatible materials, ordering them together eliminates a second delivery, reduces waste on specialty cuts, and often qualifies for volume pricing from suppliers. For flooring that runs through the kitchen and into the hall toward the baths, a single purchase and installation is significantly cheaper than two separate cut-and-install passes.

The Electrical and Plumbing Argument

If your Rancho Murieta home needs a panel upgrade, it almost certainly needs it for both the kitchen and the bathrooms. A 100-amp panel being upgraded to 200 amps to accommodate a kitchen with modern appliances can have circuits for bathroom exhaust fans, heated floors, and GFCI protection added to the same upgrade at marginal additional cost. The electrician is already replacing the panel.

The same logic applies to plumbing. If you are opening walls for kitchen supply line replacement, having the plumber trace and replace the supply lines to the bathrooms in the same visit costs significantly less than a second open-walls-and-replumb visit. The labor for the second visit is half opening drywall and half actually replacing lines.

Sequencing a Combined Project

The sequence for a combined kitchen and bath project matters. ADC typically runs it as follows:

• Demo all rooms simultaneously, pull all tile, cabinetry, and finished surfaces at once. All the dust happens in one phase.
• Rough plumbing in all rooms, with walls open in all spaces, the plumber completes all rough-in before any walls close.
• Rough electrical in all rooms, same logic; electrician runs all circuits before drywall.
• Rough inspection, one inspection covers all rooms. This is the key scheduling win over separate projects.
• Insulation, then drywall, all rooms close at the same time.
• Tile and flooring, tile setters work kitchen and baths in sequence; no re-mobilization.
• Cabinet installation, kitchen cabinets, then bath vanities.
• Fixtures, appliances, finish hardware, final phase in all rooms simultaneously.
• Final inspection, one inspection covers the full scope.

The Tradeoffs to Know

A combined project means both the kitchen and at least one bathroom are out of service at the same time during the rough-in and framing phase, typically 2 to 4 weeks. For families who cannot comfortably use a single remaining bath during that period, this can require temporary relocation or use of a rental property. The same disruption over a series of single-room projects would be shorter each time but repeated over years.

ADC stages the project to ensure at least one functional bathroom remains accessible whenever possible. On projects with a master bath and two secondary baths, the secondary baths are often started after the master bath reaches a functional stage, keeping one bath active throughout most of the project. Call (209) 200-5302 to discuss how a combined project would be sequenced for your specific home.

When It Does Not Make Sense to Combine

If the kitchen and baths are on a different remodel timeline for quality or budget reasons, forcing them together is not always right. A homeowner who wants a premium kitchen with custom cabinetry and is comfortable with standard contractor-grade baths may not benefit from the same tile-and-material coordination efficiencies. A very small secondary bath that only needs cosmetic updates (new fixtures, reglazing) can often be separated from a full kitchen gut without much cost penalty.

The case for combining is strongest when: the home’s plumbing and electrical both need upgrades, the finish materials have meaningful overlap, and the disruption timeline matters more than spreading the cost. Call ADC to discuss whether your specific scope and home layout make the combined approach the right call for Rancho Murieta.
