What is bathroom remodel plumbing?
Bathroom remodel plumbing is every line your new bathroom uses. That means the drains from the shower, tub, toilet and sink. It means the vents that keep those drains flowing. It also means the hot and cold lines and the valve that mixes them in the shower.
Almost all of it ends up behind tile or under the floor. Once the tile is set, fixing a plumbing mistake means tearing it out. That’s why the plumbing gets planned first.
What bathroom plumbing jobs are most common?
Grand Rapids homeowners ask us about these jobs most:
- Tub-to-shower conversions. Swapping an old tub for a walk-in shower.
- Walk-in and curbless showers. New drains, linear drains and the slope they need.
- Shower valve replacement. Anti-scald valves that keep the temperature steady.
- Toilet replacement. Water-saving toilets, new flanges and fixing a rocking toilet.
- Vanity sinks and faucets. Single to double vanities and new supply lines.
- Basement bathrooms. Rough-ins, ejector pits and up-flush systems.
Each one has its own page with costs, timelines and questions to ask. All six are on the services page, and the 2026 cost guide puts the price ranges side by side.
When does the plumber work during a remodel?
A bathroom plumber usually visits three times:
- Planning visit. Before demo, to check the drains and price the job.
- Rough-in. With the walls open, to set drains, vents, supply lines and the shower valve. An inspector checks this stage when a permit is required.
- Trim-out. After tile and paint, to set the toilet, faucets, showerhead and trim.
The shower valve is the part people forget. It goes in during rough-in, long before you see the handle. Pick your shower trim before the walls close.
Why hire a licensed plumber in Michigan?
Michigan licenses plumbing contractors through the state’s Bureau of Construction Codes. A licensed contractor pulls the permit, knows the Michigan Plumbing Code and warranties the work.
Bathrooms are where bad plumbing does the most damage. A slow leak under a shower pan can rot a subfloor for years before anyone sees it. A licensed pro tests the drain and pan before the tile goes on.

Common questions
Do I need a plumber for a bathroom remodel?
You need a licensed plumber for anything that moves a drain, adds a fixture or replaces a shower valve inside the wall. That work usually needs a permit and an inspection before the wall is closed. Swapping a toilet or faucet on the same lines is simpler. Even then, a pro checks the shutoffs, flange and seals so a slow leak doesn’t soak your new floor.
How much does bathroom remodel plumbing cost in Grand Rapids?
Most Grand Rapids bathroom remodels spend about $1,500 to $7,000 on plumbing. Swapping fixtures where they already are sits at the low end. A tub-to-shower conversion, a curbless shower or a new basement bathroom sits at the high end. These are planning ranges, not quotes. The 2026 cost guide breaks the price down job by job.
Is this service free?
Yes. You never pay us anything. We pass your request to one licensed plumbing contractor, and they quote you directly. You can compare that quote with others, ask questions or simply say no. There’s no fee, no contract and no calls from other companies. If the partner plumber pays us for the referral, that never changes your price.
Are you a plumbing company?
No. Bathroom Remodel Grand Rapids is a free referral service run by 45Squared LLC, a Midwest web studio. We write plain-English guides to bathroom plumbing and connect homeowners with one independent, licensed Michigan plumbing contractor. That contractor sets the price, does the work and stands behind it. You can check any Michigan contractor’s license with the state.
