What a bathroom remodel in Pasadena includes
A full bathroom remodel takes the room to the studs and rebuilds it: new supply and drain lines where they need it, a new shower valve, a waterproofed shower or tub surround, tile, a vanity and top, a toilet, lighting, a vented fan and paint. A partial remodel keeps the tub or the layout and replaces the rest. Either way, once a fixture or wallboard is replaced, the City of Pasadena wants a permit before work starts.
- Tile cracking or loose at the tub line, or grout that stays dark: water is getting behind it
- A soft spot at the base of the toilet or a stain on the ceiling below
- Only two-prong outlets, or none near the sink
- A fan that doesn't vent outside, or no fan at all and paint peeling on the ceiling
- A shower valve that runs scalding when someone flushes
- One bath for the whole household and a hall closet that could become a second
Behind the tile in an older Pasadena bath
Most of the cost surprises in a Pasadena bathroom remodel come from the house's age, not the new finishes. Bungalow Heaven's 800-plus Craftsman homes were built between 1900 and 1930, and the city's later ranches are still mostly older than 1994. Four things come up again and again:
Galvanized supply pipe and old drains
Steel supply lines rust from the inside and lose pressure. Once the wall is open, replacing the run back to the main line costs far less than opening the same wall again in five years.
Wiring that predates bathroom circuits
The City's handout calls for at least one 120-volt, 20-amp circuit serving the bathroom receptacles and nothing else, GFCI protection, tamper-resistant receptacles and no receptacle over the tub or inside the shower. A bath fed from a bedroom circuit needs a new run from the panel.
The window in the shower
Many older baths have a window over the tub. Glass in a wall that encloses a tub or shower, with its bottom edge less than 60 inches above the standing surface, has to be safety glazing. A remodel either replaces it with tempered glass or moves the shower.
The whole-house fixture rule
On houses built before January 1, 1994, a remodel permit triggers California Civil Code 1101.4: older high-flow toilets, showerheads and faucets anywhere in the house get replaced with water-conserving ones, not just in the bath being remodeled. Details are in the Title 24 and CALGreen guide.

How a bathroom remodel runs
- 1Measure and decide the layout
Keep the plumbing where it is, or move it. Moving a toilet or shower drain is the biggest single cost decision, so it gets made before anything is ordered.
- 2Plans and the City permit
A site plan and a dimensioned floor plan of the bath and the rooms beside it; existing and proposed plans if the layout changes. Pasadena may review a simple bath at the counter.
- 3Demolition and what it uncovers
Tile, tub and wallboard come out. Old galvanized pipe, rotted subfloor at the toilet and ungrounded wiring are found here, and the scope is confirmed.
- 4Rough plumbing, electrical and fan
New valve, drains and supply lines, a dedicated 20-amp GFCI circuit, the fan duct to the outside, then the rough inspection before walls close.
- 5Waterproofing, tile and glass
Backer board and a waterproof membrane in the wet areas, tile to at least 6 feet above the floor at the shower, then tempered glass.
- 6Fixtures, final inspection and sign-off
Vanity, toilet, trim, lighting and the fan go in; the final inspection closes the permit.
