A popular swimming pool is set to close for repairs for almost three months.
The main pool at Alfreton Leisure Centre will be shut from Monday until the end of November after tiles came loose from its base.
Customers have voiced disappointment at the closure – but bosses insist the repairs are essential.
Peter Sharkey, general manager at Alfreton Leisure Centre, said: “We’re investigating why the tiles came loose – it’s perplexing.
“It is disappointing we’re having to close the pool but these things do happen.
“We’re doing everything we can to minimise the disruption and inconvenience this will cause to our customers.”
On Facebook, Jessica Wolden said: “I use the pool three times a week and now I won’t be able to and I will still be paying for it.
“It’s poor customer service.”
However, Mr Sharkey said members could use the pools at either Ripley or Heanor lesiure centres or freeze their current membership free of charge.
Customers are also being reminded the smaller pools at the centre are open as normal.
Councillor Tony Holmes, cabinet member for housing and public health at Amber Valley Borough Council, said: “We are disappointed that the pool has to close, particularly as it only opened in 2009 and is so well used by the public.
“We appreciate that our regular swimmers will be inconvenienced during the autumn but the timetable for the repairs was planned to ensure that the pool was available throughout the school summer holidays.”
