Bathtub replacement is one of the more involved plumbing jobs in a bathroom because access is tight, the drain and overflow assembly has to be installed before the tub is set, and getting the tub level and properly supported affects how every connection fits. A tub that is not set correctly will leak, rock, or flex in ways that show up later as cracked caulk, failed seals, or water behind the walls. Whether you are doing a straightforward tub-for-tub swap or switching to a completely different style as part of a larger Bathroom Remodeling, the installation process matters as much as the tub itself.












Tub Types We Install
Alcove Tubs
The most common tub style in Mid-Michigan homes, set into a three-wall enclosure. Replacement involves removing the old unit, inspecting the subfloor and wall framing for moisture damage, leveling the new tub, and connecting the drain, overflow, and supply before the surround goes in.
Freestanding Tubs
Freestanding soaking tubs require floor-mounted supply connections and a freestanding or floor-mounted drain. The supply rough-in has to be positioned precisely for the filler to align correctly with the tub's finished placement. These tubs are also significantly heavier than standard units, and the floor structure needs to be assessed before installation.
Drop-In Tubs
Set into a deck or platform, drop-in tubs require the drain rough-in to align with the tub's drain location before the deck is built. We coordinate with your contractor or handle the rough-in as a standalone scope.
Tub-to-Shower Conversions
When an existing tub is being removed and replaced with a walk-in shower, drain relocation and new valve rough-in are part of the scope, the same work covered in more depth on our Shower Installation page.
Converting From a Tub to a Shower?
A tub-to-shower conversion is one of the more common reasons people replace a bathtub, and the plumbing side of it is different enough from a straight tub swap that it is worth understanding before you commit to a layout. Once the tub is out, we relocate the drain to match the new shower base and rough in the valve at the position and depth the new enclosure requires, the same drain and valve work covered in more detail on our Shower Installation page. If you are planning this kind of conversion, it is worth looking at both pages together since the finished result is really a shower installation that starts with a tub removal.

Our Bathtub Installation Process
Remove & Inspect
Before the new tub goes in, we remove the existing unit and inspect the subfloor and framing for any moisture damage, verifying the floor can support the weight of the new tub, particularly for heavier freestanding and cast iron models.
Connect Drain & Overflow
The drain and overflow assembly is connected before the tub is set in place.
Level, Secure & Connect
We level the tub, secure it according to the manufacturer's requirements, make all supply and drain connections, and test for leaks before the surround or deck work proceeds.
Finish Freestanding Connections
For freestanding tubs, supply connections are made to the floor rough-in and the freestanding filler is installed and tested.

Bathtub Installation Cost in Okemos, MI
A standard alcove tub replacement in good existing condition is one of the more straightforward tub jobs. Freestanding and drop-in installations are more involved due to supply positioning and coordination with surrounding finish work. Any subfloor repair or drain relocation adds to the scope. We give you a complete quote after a site assessment. Call (517) 742-2848 to talk through your tub project.
Why Choose Plumbing by Custom Built
A bathtub installation done correctly is one you will not have to think about again. Done incorrectly, the first sign of a problem is usually water where it should not be. We take the time to do the rough-in, leveling, and connection work properly so the tub performs the way it should for the long term.

FAQs
How long does bathtub replacement take in Okemos, MI?
A standard alcove tub swap is typically completed in one day. Freestanding tub installations that require floor rough-in modifications may take longer depending on existing conditions.
Do I need to check the floor before installing a freestanding tub in Okemos?
Yes. Cast iron and stone resin freestanding tubs can weigh 300 to 500 pounds or more when filled with water. The floor structure needs to be adequate to support that load. We assess this before installation and flag any concerns before the tub is ordered.
Can I keep the existing surround when replacing an alcove tub in Okemos, MI?
Sometimes, but it depends on the condition of the surround and whether the new tub's dimensions match the existing opening.
What happens if there is water damage under the old tub in Okemos?
We document and show you what we find. Subfloor repairs need to happen before a new tub goes in.
Should I replace my bathtub or have it refinished instead?
Refinishing can be a reasonable option if the tub itself is structurally sound and the issue is purely cosmetic, a chipped or dull finish, but it doesn't address anything going on with the drain, overflow, or the condition of what's behind the tub. If there's any doubt about what's underneath, or the tub is original to the home, replacement gives you the chance to actually see and address what's there instead of covering it back up.
