Hotel Pool Surround Testing

Why hotel pool slip claims are different

A hotel guest who slips on a pool surround presents a different evidential picture to a customer who slips in a hotel restaurant. The guest was barefoot rather than shod; the surface was foreseeably wet rather than occasionally wet; and the duty of care toward a guest in a pool environment is interpreted strictly because the contributing factors are entirely under the operator's control.

Pendulum testing of the pool surround — with the correct slider for barefoot conditions — is the central technical evidence in any defended claim. Standard Slider 96 testing, even at acceptable PTV levels, will be challenged by a competent claimant expert who points out that the slider does not represent the actual pedestrian.

Slider 55 and Slider 57

Both sliders simulate barefoot wet contact, with subtly different applications:

• Slider 55 — TRL rubber, 55 IRHD hardness. The standard slider for barefoot wet pool surrounds, communal showers and hydrotherapy approach zones.
• Slider 57 — simulated soft sole, 57 IRHD hardness. Used where the user population includes hotel slippers, towelling shoes or pool shoes — common in spa-resort pool decks and adult-only luxury pools.

For comprehensive hotel pool testing, both sliders may be appropriate — Slider 55 for the genuinely barefoot zones and Slider 57 for the slipper-and-spa-shoe zones. The report identifies which slider was used at which location and why.

PTV thresholds for hotel pool surrounds

The HSE PTV bands (0–24 high, 25–35 moderate, 36+ low) apply to pool environments using the appropriate barefoot slider. For hotel pool surrounds we apply:

Zone	Target wet PTV (Slider 55)
Pool surround main walking area	36+
Pool steps and ladder approach	40+
Hydrotherapy pool surround (where present)	40+
Sloped wet zones (pool ramps, beach entries)	45+
Shower cubicles and communal showers	40+

Common findings on hotel pool surrounds

From the hotel pool testing we deliver, recurring issues include:

• Polished natural-stone surrounds that look luxurious but achieve barefoot PTV in the moderate band even when new
• Tile installations originally compliant that have polished down through years of chemical-cleaning regimes
• Step nosings replaced as part of repair works with smoother material than originally specified
• Salt-water chlorinated pools where surface chemistry has degraded faster than the operator expected
• Decorative mosaic features at the water line that perform very differently to the main surround tile
• Transition zones from carpeted pool-deck loungers onto wet tile — the joint itself is a fall point

How testing fits the operating year

For hotel pools, testing is most useful when it captures realistic operational conditions:

• End-of-day testing — after a full day of guest use, with the cumulative pool-water chemistry and sun-cream residue typical of summer operation
• Mid-cleaning-cycle testing — not immediately after a deep clean, when the surface is in best condition
• Seasonal testing — for outdoor or seasonal pool decks, twice-yearly periodic testing captures both summer and winter conditions

Surface roughness Rz as forensic supplement

Pendulum data tells us the dynamic friction; Rz measurement tells us the surface texture that produces it. For hotel pool surrounds, Rz is particularly useful when:

• The pendulum result is borderline (PTV 25–35 moderate band) and the surface texture data informs whether the result is texture-driven or chemistry-driven
• An anti-slip treatment has been applied and verification of texture change is needed
• Long-term wear monitoring is being delivered — Rz changes are often an earlier indicator than PTV

Rz testing is a UKAS-accredited stylus-roughness method, and the HSE has a published Rz/wet-slip-risk correlation that complements PTV data.

What hotel groups instruct us to do

For multi-property hotel groups we deliver:

• Annual or bi-annual periodic testing across pool estate
• Pre-acquisition pool-surround due diligence on hotels being acquired
• Post-renovation testing to verify a refurbished pool surround meets specification
• Forensic post-incident testing within days of a guest slip incident
• Anti-slip treatment verification on remediated pool surrounds

Reports are structured to satisfy both insurer documentary requirements and CPR Part 35 expert-evidence requirements where claims arise.
