Every decision a bathroom renovation needs
Most bathroom projects do not go wrong on the big choices. They go wrong on the twenty-eighth one nobody wrote down — the drain style, the niche size, the trim where the wall tile meets the shower — discovered on the day the tile setter needs an answer. This is the full list, grouped the way a contractor asks for it.

The decisions every bathroom has
Regardless of layout: vanity, vanity top, sink basin, vanity faucet, mirror, lighting, floor, wall finish, toilet, towel storage, and towel bars or hooks. The vanity top and basin are separate decisions only when the vanity line you choose does not include them — which is exactly the kind of thing that turns into a delay when it surfaces late.
If there is a shower
Shower floor, shower wall, drain, and the faucet and valve trim, plus a shower door if the enclosure takes one — a walk-in or a curtain does not. Then the ones that depend on how the shower is built: a niche carries a size, not just a tile; a bench needs a bench top; a curb needs a curb top, unless the entry is curbless, in which case neither exists and neither does the transition between shower floor and bathroom floor.
If there is a tub
Tub, tub filler, and — for undermount or alcove tubs only — a surround. A freestanding tub has no surround and no deck-to-floor transition, so two decisions disappear the moment you choose one. Tub fillers split further: floor-mounted, deck-mounted and wall-mounted are different rough-ins, which makes this a plumbing decision disguised as a finish decision.
The ones people forget
Grout is chosen with the tile and bought separately, so it belongs on the order even though it is not a row on most lists. Trim between the wall and the shower wall, and the transition between two floor surfaces, exist only because two things you already chose meet each other. And the shower installation materials — tray, foam board, curb base, waterproofing strips, screws and washers, drain flange — are invisible in every photograph and stop the job when they are missing.
Why the list is not the same for every bathroom
A primary bath with a bench has decisions a kids bath does not. A curbless shower removes three. Sightline reads the list off your actual room rather than handing everyone the same twenty-eight rows: what you have already settled in conversation is filled in, what is genuinely still open is what you are asked about, and decisions that cannot exist in your layout are never raised.
Frequently asked questions
How many decisions is a bathroom, really?
A bathroom with both a shower and a tub runs to roughly twenty-eight, before finishes are broken down by supplier. A powder room can be under ten. The count matters less than which ones apply to your room.
What is the one people most often miss?
Waterproofing and setting materials for the shower. They are invisible in any render, so they are absent from every mood board, and they hold up the job when they are not on site.
Do I have to decide everything before starting?
No. Order matters more than completeness — anything that changes plumbing or framing has to be settled before those trades, while paint and hardware can wait.
