Tub-to-Shower Conversions in Nampa, Idaho
Removing a tub nobody uses and rebuilding the space as a full-size, properly drained shower.
Short answer
Conversions are the highest-value project we do in Nampa, because so many homes here have a single small bathroom built around an alcove tub. Trading it for a shower changes how the room works every day, and the drain usually stays where it is.

What tub-to-shower conversion includes in Nampa
- Removal of the tub — cast iron and one-piece units come out in sections
- Capping or rerouting tub supply lines and adapting the waste line
- Framing and subfloor repair at the apron and valve wall
- New pressure-balancing valve set to shower height
- Pre-sloped pan and bonded waterproofing across pan, curb and walls
- Tile or panel finish, niche in an existing stud bay, glass door or screen
What we find in Nampa homes
- Mid-century Nampa alcoves frequently have a cast-iron tub and a galvanized drain stub. Both come out during the conversion, and replacing the stub now avoids opening the floor again later.
- Water damage at the valve wall is common where a surround was glued over the original tile — we plan for framing repair rather than treating it as a surprise.
- Where the bathroom is the only full bath in the house, we sequence the work tightly and keep the out-of-service window as short as the cure times allow.
What moves the price
A conversion inside an existing 60-inch alcove is usually the least expensive way into a real shower, because the drain often stays where it is. Cost climbs when the drain has to move or the framing behind the tub has taken water.
- Framing and subfloor repair once the tub and surround come out
- Drain stub replacement in older homes
- Finish choices — a straightforward tile layout keeps a conversion in the most accessible part of the range
Systems and materials we use
- Pre-sloped pans sized to standard 60-inch alcoves
- Bonded sheet membrane or liquid-applied waterproofing
- Subway, porcelain field tile, mosaic floors or acrylic panels
- Sliding, hinged or fixed-panel glass

Permits in Nampa
City of Nampa Building Safety Department
Permit and inspection requirements for shower work are set by the local building authority and change over time. Plumbing changes, drain relocation and electrical work commonly require a permit; a like-for-like surface replacement often does not. We confirm current requirements with the jurisdiction before scheduling, and we pull the permits our scope requires. For Nampa addresses, that is the City of Nampa Building Safety Department.

Tub-to-Shower Conversions in Nampa — questions
- Is a conversion cheaper than a full remodel?
- Generally yes, when the alcove and the drain stay put. The scope is contained to the wet area, and that is the main reason conversions are the most common project in this market.
- What if the bathroom is the only one in the house?
- We plan the sequence around it and tell you honestly how many days the room is unusable. The schedule is driven by cure and inspection times rather than by labour hours.
