Written and reviewed by the HomeCostGuide editorial team
Quick answer
$18k–$25k
A primary bathroom remodel that includes a layout change typically runs $18,000–$25,000. This scope goes beyond a like-for-like refresh — plumbing fixtures move to new locations, the footprint may expand into an adjacent closet or bedroom, and a custom tile shower or freestanding tub is common at this tier. Moving plumbing means re-routing supply and drain lines, which adds both material and inspection cost beyond a standard remodel. Projects that expand the room's footprint or add a second vanity push toward the high end of this range or beyond it entirely.
How this differs from a full bathroom remodel
This page covers bathroom remodels where the layout changes — plumbing fixtures move, the footprint expands, or a second vanity is added — not a like-for-like refresh. For a small bathroom or powder room kept in its existing layout, see our small bathroom remodel cost page instead; for the full breakdown across every tier, see the full bathroom remodel cost guide.

What's typically included
Included at this scope
- Relocating plumbing fixtures (tub, toilet, or vanity) to new positions
- Custom tile shower or freestanding tub
- Expanding the footprint into adjacent space

Not included (see the full guide)
- Small bathroom and powder room refreshes (see the small bathroom remodel cost page)
- Structural additions beyond the existing room envelope
- Whole-house plumbing or electrical panel upgrades
What affects the price
- Plumbing relocation
- Moving a toilet, tub, or vanity drain even a few feet requires breaking into the slab or subfloor and re-routing lines — the single biggest cost driver at this tier.
- Footprint expansion
- Borrowing space from an adjacent closet or bedroom adds framing, electrical, and HVAC work beyond the bathroom itself.
- Custom tile and fixtures
- A curbless tile shower, freestanding tub, and designer fixtures are far more common — and costly — at this scope than in a standard remodel.
Frequently asked questions
How much more does moving plumbing add to a bathroom remodel?+
Relocating fixtures typically adds several thousand dollars over a like-for-like layout, largely from breaking into and re-routing supply and drain lines, plus the added inspection step most jurisdictions require for plumbing work.
Is a primary bathroom remodel worth doing before selling?+
It can be, though upscale primary-bath remodels recoup a lower share of their cost than a standard midrange bathroom remodel — see the resale value section of the full bathroom remodel guide for sourced figures.
