SHOWERS & TUBS
Tub-to-shower conversions
Replace an existing tub with a shower that fits the alcove and the way the room is used. Drain location, wall condition, threshold height, and enclosure style are resolved together before selecting a base and walls.
START WITH THE DETAILS
What goes into
the work.
Measure the existing base and wall height. Record drain location and threshold. Final product dimensions and waterproofing compatibility need verification.
Typical scope to confirm
- Remove the specified tub and surrounding finishes
- Verify drain, supply, framing, and substrate conditions
- Install the selected shower base, wall system, valve, and enclosure as listed
Make it specific to your project.
Enter the amount of work and choose the details you know. Your choices follow you into the Project Builder.
LOW / MIDDLE / HIGH REFERENCE
Low$1,000per project
Middle$4,500per project
High$8,000per project
Low and high are published reference endpoints. Middle is their arithmetic midpoint, not a quoted average, product tier or firm price.
Match the reference scope first
- Confirm Base system before applying this reference to your quantity. The reference covers a prefabricated receptor/stall, not a tiled pan, bathtub or retained base.
- Confirm Wall system before applying this reference to your quantity. The displayed conversion/stall range is prefabricated, not a custom tiled shower.
The figures above remain the source reference. They do not price these selections or a complete installed project.
A planning reference for this service only. Selections, local labor, access, quantities and existing conditions need Coastal’s review. Do not add overlapping whole-project and component ranges.

PERMIT PLANNING
Check the scope and jurisdiction
New or altered electrical, plumbing and mechanical systems need permit review. Edmond lists limited minor-repair exceptions; OKC directs permitted trade work through licensed, registered contractors.
- New circuits, relocated fixtures or altered piping
- New or altered heating, cooling, gas or exhaust systems
- Changes beyond the local minor-repair exemption
ENGINEERING & DESIGN
Engineering is not usually needed
Engineering is not usually part of this finish-only scope. Stop for review if hidden damage, structural changes or unusual support loads are found.
- New structural work or damaged framing
- Unverified heavy-load support
Confirm requirements with the city or county responsible for the property before work begins. The address, exact scope and adopted code determine the final requirements.
