In the Leadership Panel meeting at County Buildings it was approved to demolish the pool, harbour pavilion and toilets.
No decision has been made as to when it will take place but it could be from now to within the next 12 months.
The news also comes as the final nail in the coffin for hopes to save the swimming pool from this long-anticipated fate.
Girvan and South Carrick Councillor John McDowall is upset that the Leadership Panel has agreed to demolish the pool and feels the current administration has ignored people's wishes.
He said: "I am very concerned that the Leadership Panel have given approval for the demolition of Girvan Swimming Pool, shops and harbour toilets.
"This could take place at any point between now and next year. I have consistently argued that no demolition should take place until there is a clear strategy for the replacement of the pool and that there should be consultation with the local community prior to any demolition.
"I have made this clear to senior officers of the council and elected members. It is disappointing that the Leadership Panel have approved this as part of the Asset Management Plan, without any discussion on Girvan whatsoever and whilst we are still engaged in discussions at a local level, it indicates to me that the Tory and SNP councillors on this Panel have learned nothing from the public reaction to the closure of the pool and continue to treat the people of Girvan with contempt.
"It is interesting to compare this decision to close and now demolish the pool and toilets, with the decision to invest over £3.7 million in Troon concert halls."
Can the people of Girvan now expect similar levels of investment in their community?"
Mr McDowall was also disappointed that this taken was taken without any discussion by the Leadership Panel at Tuesday's meeting.
With the demolition of the buildings in the immediate area, it means there will be no public toilets at Girvan Harbour - a popular tourist stopping spot.
The news has not been welcomed by local businesses who are really in fear for their futures.
One concerned businessman told the Gazette: "We were told the toilets at the Pavilion would be closed in July and when that happens there will be no toilets at the harbour at all.
"We get a lot of passing trade from the coaches coming from Ireland and if there are no toilet facilities on offer they won't stop pure and simple."
South Ayrshire Council's Property Asset Management Plan also recommended the sale of the Girvan Town House and Girvan Registration Office.
The Town House currently houses the District Court, which meets infrequently, and Girvan Horizons.
Serious consideration is being given to moving the registration service within the One-Stop Shop and relocating Social Work elsewhere in the short-term to allow this property to be sold off.
