Tub-to-Shower Conversions in Star, Idaho
Removing a tub nobody uses and rebuilding the space as a full-size, properly drained shower.
Short answer
Tub-to-shower conversions in Star are usually in secondary bathrooms — a standard alcove tub that nobody uses in a home where the master already has a shower. The alcove and the drain stay put, which makes it one of the more predictable projects we quote.

What tub-to-shower conversion includes in Star
- 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 Star homes
- Star's newer alcoves are square and consistently framed, so tile layout is straightforward and the labour is easy to estimate accurately.
- Builder tub valves in these homes are typically the original cartridge. We replace the valve during a conversion rather than tiling a wall shut around it.
- Where the home is single-level on crawlspace, adapting the waste line for a shower drain is simple work from below.
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.
- Whether the drain relocates or the existing tub waste can be adapted in place
- Tile choice, since a straightforward field tile layout costs meaningfully less than mosaic or herringbone
- Door type — a sliding door on an alcove versus a frameless hinged panel
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 Star
City of Star Building 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 Star addresses, that is the City of Star Building Department; addresses outside city limits fall under Ada County.

Tub-to-Shower Conversions in Star — questions
- Should we keep one tub in a Star home?
- If it is the only tub and you may sell to a family, keeping one somewhere in the house is the safer call. If the home has two, converting the unused one is an easy decision.
- How long does an alcove conversion take?
- Typically two to two and a half weeks on site. Cure and inspection times and the glass template set the schedule.
