Shower Remodeling in Los Angeles: Pan, Drain, and Waterproofing First

The shower is a system, not a surface

A shower is a small room inside a room, and every part of it has to move water in one direction: toward the drain. The pan is sloped, the membrane sits behind the tile, the joints are finished at every change of plane, and the glass and controls are placed so they can be reached from the entry.

Entry styles are the first visible decision: a low curb, a level entry, or a wet-room layout where the shower floor continues into the room. Each one changes how the pan is built and where the drain sits, so the entry is decided before the pan, not after. Glass, controls, seating, and storage niches follow the same rule: settled in the plan, because moving any of them after the pan is set means opening finished work.

After the rebuild, the shower is looked after like any wet area: grout and caulk at the corners are watched for gaps, glass is wiped down, and the drain is kept clear. Early signs of trouble are damp spots, a musty smell that lingers, or grout pulling away at the joints, and each one is worth a look before it reaches the framing below.

• ✓ Decide the entry before the pan is built
• ✓ Settle glass, controls, and seating in the plan
• ✓ Ask what sits behind the tile
• ✓ Test the pan before the tile goes on

Level entry, low curb, or wet room?

A level entry or a wet-room layout makes sense when easy access matters or when the room should read as one open space. Both need the floor built to fall toward the drain across a wider area, and both are decided before the pan is formed.

A low curb makes sense when a defined shower area suits the room and the existing floor levels favor it. The curb holds water in the shower zone and the pan inside it is sloped to the drain. The walkthrough settles which entry fits the floor that is already there.
