Shower & Bathtub Installation in Denton, TX
Converting an old tub to a walk-in shower, replacing a cracked bathtub or fixing a shower valve that drips all day. Shower and bathtub installation in Denton, TX covers the plumbing behind the wall and under the floor, done to code.
What the plumbing side of a bathroom job covers
Shower and bathtub installation means setting the valve, supply lines, drain and overflow for a new tub or shower, or replacing them in an existing one. Tile, glass and drywall are usually separate trades, though a plumber coordinates the rough-in with them.
The rough-in happens before walls close: the mixing valve at the right height, supply lines secured, the drain located and the shower pan or tub set level. Mistakes here are expensive to fix once tile is up.
A leaking shower valve is often the reason these projects start. Stains on the ceiling below an upstairs bathroom are a common first sign, and a proper leak test confirms whether the valve, the drain or the pan is to blame.
Common bathroom projects
Here is what each involves on the plumbing side.
| Project | Plumbing work | Watch for |
|---|---|---|
| Tub-to-shower conversion. | Move the drain, set a shower pan, raise the valve and head. | The drain location under a slab may need concrete work. |
| Tub replacement. | Disconnect and reconnect drain and overflow, reset supply. | Getting a new tub through a narrow doorway. |
| Shower valve replacement. | Open the wall or access panel, replace the valve body. | Matching trim to the new valve. |
| Walk-in or low-threshold shower. | Linear or center drain, low-profile pan. | Floor slope and waterproofing. |
Safety steps worth adding to a new shower
A new shower or tub is the easiest time to add these.
- A pressure-balancing or thermostatic valve, which limits scalding when someone flushes a toilet or starts the dishwasher.
- A handheld shower head on a slide bar for seated bathing.
- Blocking in the wall for grab bars, added before tile goes up.
- A low-threshold entry, popular in 55-plus communities like Robson Ranch.
Slab homes, drains and code
Most Denton homes are on slabs, so moving a shower drain even a foot means cutting concrete to reroute the drain line. It is routine work, but it adds cost and a day or two to the schedule.
Work inside city limits follows the 2021 International Plumbing Code (IPC). Replacing a valve, moving a drain or adding a new fixture usually needs a permit and inspection before the wall is closed.
Hard water affects showers too. Scale clogs showerheads and stiffens valve cartridges. If the water is hard enough to crust fixtures, a water softener keeps new fixtures looking and working like new. For faucet parts at the vanity, see vanity faucet repairs.
Leaks behind the tile
A shower can leak in three places: the valve inside the wall, the drain connection under the floor or the pan and waterproofing beneath the tile. Each looks similar from the room below, so the source has to be tested.
A flood test on the pan, a pressure test on the valve and a check of the drain seal usually separate the three. Fixing the right one first avoids tearing out tile that did not need to come out.
Moisture meters and a thermal camera help map how far water has traveled under the floor or inside the wall before anything is opened.
Valve leaks are the easiest to fix. Pan and waterproofing failures usually mean the shower floor has to be rebuilt, which is often when owners decide to convert or upgrade the whole shower.
What shower and tub work costs depend on
Bathroom plumbing costs vary more than most jobs.
- Whether the drain moves, especially through a slab.
- Valve type, standard or thermostatic.
- Tub or pan material and size.
- Access from behind the wall or through the tile.
- Permits and coordination with tile and glass trades.
