Tub-to-Shower Conversions in Boise, Idaho

Removing a tub nobody uses and rebuilding the space as a full-size, properly drained shower.

Short answer

Tub-to-shower conversions are the most common single project we do in Boise, because so much of the housing stock is a 60-inch alcove tub that the household has stopped using. Inside an existing alcove, the drain usually stays put, which makes it the most predictable way into a real shower.

What tub-to-shower conversion includes in Boise

  • 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 Boise homes

  • Cast-iron tubs are still everywhere in Boise's older neighbourhoods. They come out in sections, which is loud for an hour and much safer than carrying several hundred pounds down a narrow staircase.
  • Water behind a glued-on tub surround at the valve wall is the most frequent hidden condition we find in Boise conversions — usually two soft studs and a section of subfloor at the apron.
  • Pre-war alcoves are rarely square. We plan the tile layout so the taper lands at the back inside corner rather than in the sight line.

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 are out
  • Replacing a galvanized or cast-iron drain stub while it is accessible
  • Period-appropriate finishes — mosaic floors and subway layouts take longer to set than field tile

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

How the project runs

  1. 1Walkthrough and measurement in your bathroom, not over the phone
  2. 2Written estimate with scope, materials and the assumptions behind it
  3. 3Material selection — tile, pan, valve, glass and trim
  4. 4Permits confirmed with the local building authority where the scope requires them
  5. 5Scheduling, protection and dust control
  6. 6Demolition and inspection of what is behind the old shower
  7. 7Framing, plumbing and substrate corrections
  8. 8Waterproofing, with a flood test on the pan before tile
  9. 9Tile, grout and trim
  10. 10Glass templated to the finished walls, then installed
  11. 11Final silicone, cleanup, walkthrough and a written care summary

Permits in Boise

City of Boise Planning and Development Services

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 Boise addresses, that is the City of Boise Planning and Development Services.

Tub-to-Shower Conversions in Boise — questions

Will removing the only tub hurt my Boise home's value?
If it is the only bathtub in the house, that is worth weighing — many buyers of family homes still want one somewhere. Where a second bath has a tub, a usable shower is generally the stronger asset.
Can you keep the original look of an older Boise bathroom?
Yes. Subway tile, hex mosaic floors and chrome trim read correctly in a pre-war bathroom, and everything behind them is a modern waterproofing assembly.
