Full gut or keep the layout and swap the finishes?
Whether the bathroom is the primary or a hall bath changes the answer. In a Friendswood home from the 1980s, the primary bath often has a garden tub nobody uses, a separate shower stall too small to turn around in, and a vanity that runs the length of the wall with one sink in the middle. That room usually earns a full gut so the space can be reorganized around a real shower and double vanity. A hall bath or a kids' bath tends to be small and already laid out sensibly, so keeping the fixture locations and replacing everything in place gets most of the result for less disruption.
The trade-off is what you can change. Keeping the layout means the drain, the toilet flange, and the supply lines stay where they are, and the money goes into tile, fixtures, a new vanity, and lighting. A gut lets us move the shower to the long wall, close off a door that opens the wrong way, or steal space from an oversized closet. We lay out both options on a drawing during the walkthrough and price each so the decision is made with numbers rather than guesses. Either way the finished room gets the same waterproofing and the same attention to detail.
