Cllr Teresa Parry, vice chair of the community council, said: “The Gelligaer Community Council thought that it was very important that we take over the toilets because the county council had closed them.
“We think that it is only right for the dignity of people to have a toilet they can use and not only for the local people but also for the visitors of the town.”
Cllr Alan Angel said: “This has all been taken on by the Gelligaer Community Council, as part of the community council budget – this covers the cost of keeping them open and having people coming and cleaning on a regular basis.”
He added: “We are very pleased the community council has been allowed to take this on.
“There has been a big public response regarding them being closed.
“We are very happy that the council has allowed us to do it.”
Cllr Wynne David said: “Plaid has a majority of one on this community council, but for many years it has been run in a non-political fashion with all its resources spent fairly throughout the area.
“The decision to fund the reopening of Ystrad Mynach toilets was a unanimous one and as a Labour Councillor I found great pleasure today standing next to my colleagues celebrating the official reopening.
“This is a prime example of when Labour and Plaid work together things get done in the Community. That is why Gelligaer Community Council has achieved so much.”
Community council clerk Ceri Mortimer said: “It is very important to support the town as well as our shops and our traders.”
The public toilets will be open from 8am to 4pm between Monday and Friday, and from 7am to 3pm on Saturdays.
