Explain the changing facility gap
Describe who lacks bathroom access at each stage and which existing facilities remain usable. Discuss standard cabins, washing and accessible needs according to that gap. The business needs the use pattern as well as dates to review a suitable arrangement.
Confirm adjustments rather than assuming them
Ask how reduced quantities, added service or an extension are handled. Keep the agreed supplier route available while work continues. When the need ends, confirm the collection request and contact instead of treating reopened bathrooms as an automatic cancellation of the rental.
