Pool Surround Specification Review

Common pool specification deficiencies

• Slip resistance not referenced at all — common in older pool refurbishment specifications
• BS 7976-2 quoted as current standard — withdrawn in 2022; should reference BS EN 16165:2021 Annex C
• PTV threshold set without slider specified — Slider 55 (barefoot) gives different results from Slider 96 (shod); both methods needed for the surround/changing room boundary
• PTV threshold set too low for vulnerable users — 36+ acceptable for general adult pools, 40+ better practice for children's, hydrotherapy and care contexts
• Pool steps and ramps not differentiated from main surround — sloped wet zones warrant higher PTV than the flat surround
• Pre-handover testing not required — leaves the contractor with no evidence the installed surround meets the spec
• Periodic re-testing not included in O&M — leaves the operator without the framework for ongoing compliance

What a robust pool specification looks like

For a typical commercial pool, a robust specification will reference: BS EN 16165:2021 Annex C (formerly BS 7976-2); a minimum PTV wet of 36 (or higher for sensitive environments) using Slider 55 for the surround and Slider 96 for any shod transitions; pre-handover independent UKAS testing; periodic re-testing scheduled in the O&M manual; differentiated PTV for steps, ramps and ladders; and surface roughness Rz baseline for ongoing comparison.

The architect-and-tile-supplier interface

Many pool specifications are drafted by architects but populated with tile manufacturer datasheet language. The two do not always align cleanly. A common pattern: an architect's spec calls for 'PTV 36+ wet' while the chosen tile manufacturer's datasheet quotes only product-level ratings without in-situ PTV data. Translating those product-level ratings to in-situ wet PTV on the actual installed surround requires verification, which is best built into the specification at procurement rather than discovered post-handover.

Pool refurbishment — inheriting old specifications

Pool refurbishment projects often inherit the previous pool's specification by default. Where the new pool use differs from the original (e.g. converting a recreation pool to a learner pool, adding a hydrotherapy suite to a former leisure pool), the inherited specification may no longer be appropriate. Independent review identifies these cases before procurement.

Working with QS, main contractor and operator

For the QS team, specification review at tender stage produces fewer downstream variations and clearer compliance evidence at handover. For the main contractor, it reduces the risk of installing a non-compliant surround and being asked to remediate at their cost. For the operator, it reduces inherited risk on day one of operation.
