Freestanding Tub Plumbing: When the Lines Need to Move

The planned freestanding tub location changed where the plumbing needed to be placed. We needed to relocate it toward the center of the window rather than keep it at the existing tub’s connection points.

Here is gonna be a freestanding tub, so we need to relocate the plumbing to the middle of the window.

That is a layout-specific reason for moving plumbing. A freestanding tub does not automatically require relocation. In general, the selected tub’s drain location and faucet arrangement need to be checked against the existing connections. Settle the tub position and model together before treating the plumbing layout as final.

The tub position, vanity dimensions and shower footprint needed to agree with the plumbing layout before finishes covered the work. Choosing each item separately would leave important connection points unresolved.

For the tub, the reference point was the middle of the window. For the vanity, we planned a shorter, 72-inch unit and a sink shift to the right. The cabinet length alone did not describe that change; the sink’s position also mattered.

We planned to keep the walk-in shower the same size while rebuilding it to the framing. Keeping that footprint did not mean keeping the existing shower assembly. Its tile was coming out, a new system was planned, and the plumbing was being upgraded.

The finish plan called for LVT, or luxury vinyl tile, on the floor, tile between the selected walls and a 4-inch backsplash. Shelves would replace another vanity. For a comparable remodel, mark those boundaries on the layout so the floor, wall finishes and storage locations are defined before installation.

Verify the credentials for the plumbing business and the individuals doing the work, then confirm the approvals for the property’s scope. General-contractor registration and plumbing credentials are separate matters.

Under Washington L&I’s requirements for a licensed plumbing contractor, plumbing contracting requires the appropriate business license and individual certification. A remodeling contractor can use a licensed plumbing contractor unless appropriately licensed to perform that work itself.

We hold Washington contractor license #ANYVIHR768KB. That credential does not replace the separate plumbing credentials required for plumbing work.

For a property in Redmond, the city’s construction and permit guidance identifies separate building, plumbing, electrical, mechanical and other review routes. Broader residential work can also involve clearing and grading review. A building permit does not automatically cover every approval.

Before demolition, identify who is responsible for the applicable applications and inspections. For broader planning questions beyond the plumbing layout, see our home remodeling FAQ.
