Bathroom Remodeling
The decisions that matter most in a bathroom are the ones you will never see again once the tile goes on.

A bathroom is a small room that contains water, drainage, ventilation and electricity in close quarters. That density is why the cost per square foot is high relative to the rest of the house, and why shortcuts here surface later as damage rather than as a cosmetic disappointment.
The most consequential work — waterproofing, substrate, drainage slope and ventilation — is invisible in the finished room. Finishes are what you choose; the layers underneath are what determine whether the room lasts.

Key Decisions
Ask which waterproofing system will be used behind the tile and how it is tested before finishes go on. This is the single layer you cannot inspect afterwards and cannot repair without removing the room.
Removing the only bathtub in a house is a decision worth making deliberately rather than by default, particularly if the household may change or the property may be sold.
An exhaust fan has to be sized for the room and ducted to the outside, not into an attic. Undersized or badly routed ventilation is a common cause of recurring moisture problems in otherwise well-built bathrooms.
Older Los Angeles homes may still have original supply or drain lines. Once walls are open, it is worth knowing what is behind them and deciding in advance how you want surprises handled.
Large-format tile means fewer grout lines but demands a flatter substrate. Floor tile should be chosen for wet-surface traction, not only for how it photographs.
A curbless entry and solid blocking behind the walls cost very little while the room is open and are expensive to add later. Worth considering even if no one needs them today.
Permits
Swapping a vanity or retiling on the same layout is light work. Relocating a shower, a toilet or a drain, or adding circuits, is a different scope. In the City of Los Angeles, LADBS handles many simple bathroom remodels through an express permit without plan check; bigger changes need more. Other cities and the county set their own rules, so confirm what your scope requires at your address.
Water Fixtures
California’s Civil Code requires that, when a single-family home is altered or improved under a permit, older high-flow toilets, showerheads and faucets be replaced with water-conserving fixtures as a condition of final approval. In practice, a permitted bathroom remodel can bring fixtures elsewhere in the house into scope. Ask the contractor to check every fixture early, so the final inspection does not bring surprises.
Accessibility
A bathroom remodel is the cheapest moment to prepare for later needs.
Solid backing inside the walls costs little while they are open and lets grab bars be added later without opening tile.
A shower with no step needs the floor recessed or the drain planned differently from the start. It is a structural and waterproofing decision, not a finish choice.
A wider door and clear floor space around fixtures are easy to plan and hard to retrofit.
Ask before you commit: has someone checked which fixtures in the house must be upgraded under the permit, and is backing planned where grab bars may go later?
