A public consultation has been launched on the development of a floating swimming pool and "urban beach" in Dún Laoghaire harbour in Dublin.
The Dún Laoghaire Harbour Company said it could attract 140,000 visitors and generate up to €1m a year for the local economy.
The project could cost up to €2.5m and is envisioned to be self-financing.
A planning application should be submitted as soon as October, and the company said it hopes to have the floating pool and "urban beach" operational by the summer of 2015.
The floating swimming pool would contain heated and treated seawater, designed on a converted river barge that will be located within the harbour.
It is inspired by the floating swimming pool at Badeschiff in Berlin, Germany.
The plan also includes changing and toilet facilities and a cafe.
There will be a charge for using the facilities, including the swimming pool.
The company said this should be the same as the price of a cinema ticket.
The consultation closes on 27 September.
