Bathroom Remodel Who to call, permits & costs

Before you contact a contractor, find out what your bathroom project actually requires — permit rules for your state, realistic costs, and the right professional to call first.

What most homeowners don't know before a bathroom remodel

The single biggest cost driver in bathroom renovations isn't tiles or fixtures — it's moving plumbing. Relocating a toilet, shower, or sink can add $3,000–$9,000 to a project because it requires opening floors and walls, rerouting drain lines, and potentially re-waterproofing large areas.

Cosmetic vs. structural

A cosmetic refresh — new paint, vanity, fixtures, and mirrors without touching the plumbing layout — is the most cost-predictable bathroom project. The moment the layout changes, so does the budget and the permit requirement.

What a permit actually involves

For bathroom work that involves plumbing or electrical changes, a permit means a licensed plumber or electrician pulls the permit, the work is inspected before walls close up, and you have documented proof the work meets code. This protects you at resale and in insurance claims.

Who to call — and when

For a cosmetic refresh where you know exactly what you want, a contractor is your first call. For any layout changes, a designer helps you lock in decisions before construction starts — preventing costly changes mid-job. If walls or structural elements are involved, get architectural input first.
