The bathroom floor is the last stop on the night walk, and it is the one that gets wet. Water from the tub, the sink, and the shower can sit on it for minutes at a time, and every time someone crosses it in socks or bare feet, the top layer of the nonslip finish takes a little wear. The floor usually looks the same right up until the grip is gone. So the job is to check it on a set schedule, not to wait for the day it lets her down.

Walk the Floor in the Dark
Start at the bed, walk the route at the hour she actually makes it, and stop at the bathroom doorway. Don't switch on the big overhead light. Use the light she uses. Walk the path the way she walks it, from the doorway to the toilet, then to the sink, then back. Feel with your feet for smooth spots, places where you slide a little, and any ridge or edge where a rug or a threshold meets the floor. Write those spots down by stop number so you can find them again.
Check the Finish Where the Feet Turn
Wear shows up where feet pivot and where water runs off the edge of the tub. Look at the floor with the light angled low across it. A worn finish looks dull or shiny in a path shape, often a band running from the tub edge toward the toilet. Wet a small patch with plain water, let it dry, and compare it with a clean patch nearby. Then feel both with a bare foot. If the worn patch feels slicker than the rest, the finish has thinned there.
Read the Label Before You Clean
Find the name of the product on the floor. If you don't know it, check the installer's paperwork, the flooring box, or ask the installer. The label or installer note should tell you how to clean the floor and what not to use on it. Many floor cleaners leave a film, and many polishes and waxes make a nonslip surface slick. If the note names a cleaner, use only that cleaner. Write down the product name and any recoat interval the maker lists.
Clean, Then Test Again
Clean the floor with the named product, rinse with clean water, and let it dry completely. Then do the bare-foot walk again. Soap film alone can make a floor feel slick, and you need to know whether that is the problem before you pay for re-treatment. If the floor still feels slick after a proper clean, the finish has worn, and it is time to decide whether to re-treat it yourself or hire the work.
Decide Who Re-treats It
There are two paths. A family member can apply a coating that is compatible with the existing finish and follow the label, which is a reasonable weekend job for one bathroom if the floor is clear and the product allows it. Or a floor contractor can strip and re-texture the surface. Before you choose, ask both options the same questions: what product will be used, whether it is rated for wet bathroom floors, how long the floor must stay dry and unused before she walks on it again, and whether the work covers the full path from the tub to the toilet. Get the answers in writing. Don't compare a family job with a contractor job on price alone. Compare them on how long the floor is out of use and on what any warranty covers.
Set the Date and Name the Owner
Pick a check day and a recoat day and put both on the calendar. The check day is the day you do the bare-foot walk and the wet-patch test. The recoat day is the day the work is done or the contractor is booked. Name one person who owns the check and the call to the contractor. One name, not a group. When the check day comes around, that person does the walk, writes down what they found, and decides whether the recoat date needs to move.
What to Write Down
Keep one line for each check: the date, the product name from the label, the cleaner used, what the walk felt like at each stop, and whether the worn patch got bigger or smaller since last time. Add the next check date and the name of the person who owns it. If she slips on this floor or hurts herself on the way to the toilet, that is a question for her doctor, and the notes you keep are useful to bring to that visit.
