Slippery floors in hotels are caused by a combination of factors, including contamination,
footwear, cleaning methods, environment and the floor surface itself, not any single cause
acting alone. A floor can become dangerously slippery even when it looks clean, because grip
is a measurable property of the surface, not something visible to the eye. Understanding
which factors apply to a specific floor is the first step to controlling the risk.
The short why
Hotels combine several high-risk conditions in one building. Guests move between pool
decks, tiled floors and carpeted corridors in different footwear, cleaning happens constantly
across many surfaces, and busy service areas create spills throughout the day. Each of these
factors can lower a floor’s grip on its own, and together they compound the risk.
The six factors behind slippery hotel floors
A clear way to understand what actually causes a floor to become slippery is to look at each
contributing factor in turn.
- Contamination: spilled drinks, pool water, food debris and condensation are the most
obvious causes, and they build up fastest in bars, restaurants and around pool areas. - Heel: footwear changes throughout a hotel, from bare feet and flip-flops near the pool to
smart shoes in the lobby, and each interacts differently with the same floor. - Individual: guest behaviour matters too. Someone hurrying, carrying luggage or
distracted by their phone is more likely to slip on a floor that a careful walker would
cross safely. - Maintenance: the cleaning products and methods used on a floor can raise or lower its
grip. The wrong polish or the wrong dilution can leave a residue that reduces slip
resistance while making the floor look shinier. - Environment: lighting, gradients and floor transitions, such as moving from a tiled lobby
to a carpeted corridor, all affect how safely someone can judge and cross a surface. - Surface: the flooring material itself, and its measured slip resistance wet and dry, sets the
baseline risk before any of the other factors come into play.
Why “it looks clean” is not the same as “it’s safe”
This is where many hotels get caught out. A floor can be spotlessly clean, freshly mopped and
look completely safe, and still have a slip resistance low enough to cause a fall the moment it
becomes even slightly damp. Grip is invisible. You cannot see it, and you cannot reliably feel
it underfoot either.
This means visual inspection alone is not a slip risk assessment. It is guesswork. The only
way to know a floor’s actual slip resistance is to test it, using a method such as pendulum
testing, which gives an objective, repeatable number rather than an impression.
Does more frequent cleaning reduce the risk?
Not automatically. Cleaning removes dirt, but it does not always reduce slip risk, and in some
cases it increases it. A product chosen for shine rather than tested grip can leave a hotel lobby
looking immaculate while making it more dangerous underfoot. This is why cleaning needs
to be matched to what testing shows a floor actually needs, rather than chosen on appearance
alone.
What to do about it
Start by identifying the highest-risk areas in your hotel, typically pool surrounds, spa floors,
kitchen back-of-house areas and entrances during wet weather. From there, the most reliable
next step is getting those floors tested for actual slip resistance rather than relying on visual
checks. Once you know the measured grip of each surface, you can prioritise treatment where
it is genuinely needed instead of treating every floor the same way. Slip Safety Services has
recorded slip resistance improvements as significant as a 50,000x reduction in risk on floors
moved from a PTV of 24 to 36 or higher when wet, once the right testing and treatment were
applied.
