Bathtub Replacement in Grand Rapids

Census Bureau American Community Survey 2020-2024 estimates for the Grand Rapids metro put 15.3 percent of homes as pre-1939, 23.2 percent from 1940 to 1969, 38.2 percent from 1970 to 1999 and 23.3 percent from 2000 onward. The average year built works out to about 1980. On a tub job specifically, that shows up as two recurring line items: what the tub is made of, and what the supply piping is made of.

A cast iron tub in a pre-1970 West Michigan house is not a curiosity, it is the default. It changes the demolition, the removal route and the crew size, and none of that appears in a photograph of the bathroom. A company that has looked at the tub and identified it as cast iron is quoting a different job from a company that assumed steel or acrylic, and the two quotes will not match. That is the single most common reason a homeowner ends up holding two prices that seem to describe the same bathroom.

Galvanized supply piping is the second one. Once the wall is open at the valve, a corroded galvanized run is right there in front of the plumber, and replacing part of it usually means following it further than the original scope allowed, because a new section joined to a badly scaled old section simply moves the restriction along. This is a good outcome wearing a bad outfit: it is far better found during a planned project than during a failure, but it is money that was not in the quote, and it is worth deciding in advance how you want it handled if it appears.

Three more items turn up often enough in older stock to be worth naming before a quote conversation rather than after:

• The subfloor at the apron and the corners. Decades of small splashes at the tub edge and a slow drain leak land in the same places. This is the repair that most often turns a fixture swap into a carpentry job.
• Plaster and lath. It demolishes messily, produces far more debris than drywall, and the patch where new work meets old is its own labor line rather than a rounding error.
• Non-standard framing. True-dimension lumber, unusual stud spacing and layers of previous remodeling make the assumption of a square, plumb, standard-width alcove unsafe. A modern tub is manufactured to a standard size; a 1925 alcove is not.

The practical response is not to avoid remodeling an older house. It is to carry a contingency in your own budget separate from the quoted price, and to agree in writing before demolition how change orders are priced, who authorizes them and whether work pauses until you sign. An open-ended change order clause in an old house is how a planned project quietly becomes a much larger one. It is also worth asking how the company handles testing of older floor tile, sheet flooring and joint compound in a pre-1980 bathroom. It is a normal question, and a company with a clear process for it has done this work before.

A single-line quote for a bathtub replacement is not a price, it is a number. What separates a comparable quote from an incomparable one is whether the scope is written down, because most of the money in this job sits in items that a photograph of the bathroom does not show.

Ask for these as separate lines, and expect the total to be easier to compare across companies once they exist:

• Demolition and disposal, including whether the tub is carried out or broken up, and whether the dumpster and haul-away are in the price.
• The tub itself by manufacturer, model and material, with the exact dimensions and the drain end specified. Left-hand and right-hand drains are not interchangeable.
• Waste and overflow assembly, which is a new part on any honest replacement rather than something reused.
• The drain connection, and specifically whether the waste line under the floor is being reused, partially replaced or fully replaced.
• The valve, by type. A pressure-balancing or thermostatic valve is a different part and a different price from a basic mixer, and this is where a low quote often hides.
• Supply piping, and what happens if galvanized pipe is found once the wall is open, priced in advance rather than discovered.
• Blocking for anything that will later hang off a wall, installed while the studs are exposed. Adding it afterwards means opening a finished wall.
• Wall substrate and finish, named. Cement board, a bonded membrane system, a panel surround and a tile assembly are different products with different behavior over ten years.
• Subfloor repair at the apron and the corners, either as a stated allowance or as a written unit price.
• Patch, paint and trim where the new work meets the old room.
• The permit, who pulls it and whose name is on it.
• Change order mechanics: how they are priced, who signs, and whether work stops until you do.
• Warranty, split between the manufacturer's warranty on the fixture and the company's own warranty on its labor. These are two separate things and are often quoted as one.

Two habits are worth adopting for the quote conversation itself. First, ask each company to state its assumptions out loud, because a fixed price written before anything is opened up is a price against assumptions. Second, compare scopes before comparing totals. A cheaper quote that reuses the waste line, keeps the existing valve and excludes floor repair is not a better deal, it is a different job.

Replacing a tub is plumbing work. The City of Grand Rapids issues a residential remodel or repair permit whose fee is calculated from the declared value of the work through the city's online Estimate Fee Calculator, with separate plumbing and electrical trade permits pulled alongside it. A zoning permit for one- and two-family residential projects is $25, added to the building permit fee (City of Grand Rapids FY2027 Fee Schedule, footnote 6).

Because the building permit fee is value-based rather than a flat amount, no page can quote you a figure for it, including this one. A contractor who has run the city's calculator against your declared job value can give you the real number; one who has not will round. Trade permits are billed per fixture rather than as a single flat fee: the FY2027 Fee Schedule sets the plumbing permit application at $52 plus $5 for each fixture such as a bath tub/shower or water line (Chapter 132); if any wiring is added or moved, an electrical permit runs $52 plus $10 per device (Chapter 133); mechanical fees (Chapter 134) apply only if HVAC or venting is touched, which is unusual for a like-for-like bathtub replacement. Treat the city's calculator as the authority and ask to see the actual permit receipt when the job is done.

The permit question doubles as a screening question. Ask who pulls it and whose name goes on it. A homeowner who is asked to pull their own permit for work a contractor is performing should understand what that shifts onto them before agreeing to it.

On credentials: Michigan licenses residential builders and maintenance-and-alteration contractors through the Department of Licensing and Regulatory Affairs, known as LARA, which publishes a public license lookup. Ask for the license number, check it against that lookup yourself, and ask separately for proof of liability insurance and workers' compensation coverage sent to you directly by the insurer rather than forwarded as a photograph. That is advice about what you should verify. It is not a description of anyone.

Grand Rapids Bath Pros is operated by BetterAds Solutions LLC. It publishes this guidance and connects homeowners with an independent bathroom remodeling company. It performs no remodeling, holds no Michigan builder license, has no showroom, no installers and no completed projects, and it does not check anyone's credentials on your behalf. Everything above about licensing, insurance and permits is yours to confirm directly. How this site works and where its numbers come from is set out on the methodology page.
