The historically important art deco lido is on the English Heritage At Risk Register.
The East Sussex lido is one of many seaside attractions across England to benefit from a record £36 million government investment to boost growth in coastal areas. Words: PA
The funding will help create a community hub and 60 jobs at the grade II*-listed building, according Brighton Kemptown MP Simon Kirby.
The money, which comes from the Department for Communities and Local Government (DCLG) as part of the Coastal Communities Fund, will be used to restore the outside area and pools.
In May 2012, Brighton and Hove City Council agreed to take back control of the lido following a campaign to safeguard it, granting a 60-year lease to Saltdean Lido Community Interest Company (CIC) in December with a clear remit to restore, renovate and modernise the pool and the art deco building.
The building also gained the backing of Sir Terence Conran, whose architectural practice Conran and Partners, which specialises in art deco buildings, has drawn up restoration plans as an alternative to proposals to convert it into residential accommodation.
Rebecca Crook, director of Saltdean Lido CIC said: "Today is a major victory for local communities and heritage buildings proving that you can make things happen.
"The lido is a landmark building and the funding will enable current and future generations to enjoy the iconic swimming pool in a safe environment and with modern heated water."
Mr Kirby said: "I am delighted to be able to announce that the lido will benefit from an additional £2.3 million funding which will make a huge difference.
"I would also like to again pay tribute to the work of the CIC and also to the many local residents who have supported this campaign."

"Certain seaside towns have just about everything. Blackpool has more than everything: three piers, miles of hotels, and the iconic tower."
Mr Punch and his wife have been entertaining the English holidaymaker since 1662, and he's still going strong.
At 335ft long, Cleethorpes Pier is one of the shortest in the UK. This, year, it was sold to a venture partnership for more than £400,000.
"Lifts, trams, railways, funiculars, call them what you will, are a marvellous way to get from up there to down here and from down here to up there."
"Everyone loves a fishing boat - especially it it's wooden and being freshly painted by an old tar... along with the decline of deep-sea fishine, there has been a gradual disappearance of local fish shops, the transformations of fishermen's stroes and net shops into holiday homes, the construction of yachting marinas and the filling of harbours with pleasure craft."
"Arcades, pleasure domes, sideshows, ghosts and ghouls, crazy houses, laughing clowns, a peppering of the surreal, the unusual and the bizarre."
"Once one of the icons of the seaside amusement park, the old-style helter-skelters are fast disappearing. Only around three or four seaside helter skelters remain."
One of the Britain's many quirky places to stay, this romantic little place comes complete with its own drawbridge.
"Busy beaches are for kids to play on and for mum and dad to read the newspaper."
"George Bernard Shaw once wrote: "'Heaven, as conventionally conceived, is a place so inane, so dull, so useless, so miserable, that nobody has ever ventured to describe a whole day in heaven., though plenty of people have described a day a the seaside.'"
"Lighthouses have gradually become less important to navigation with advances in global positioning technology. Automation has led to the loss of the lighthouse keeper, although someone must still be on hand to change the bulbs."
People have been taking in the sea air and enjoying the pleasures of the North Pier since it opened to the public in 1863.
The English Seaside by Peter Williams will be published on 27 May 2013, price: £14.99.
"What can be the origin of the beach hut? Some suggest that "bathing machines" were re-used as changing rooms and then developed into picnic and sun rooms... If you like to sit in a musty, damp box full of yesterday's furniture and smelling of butane gas, listening to the rain on the roof and doing that wretched jigsaw with the missing piece, then this is for you."

Created by artist Leandro Wrlich, this optical illusion is one of three installations at the Museum of Art in Kanazawa, Japan. Erlich put two clear acrylic glasses about a foot apart and filled the space between them with water. The top surface is also filled with five inches of water to give it the effect of a real swimming pool.
Known as China's Dead Sea, this local swimming pool in Daying County, Sichuan is believed to be China's largest indoor water park and is a 30,000 square-metre salt lake, meaning swimmers float freely on the surface, just like the Middle East's Dead Sea. We're not quite sure why everyone needs rubber rings though!
Got a head for heights? You'll need one if you're thinking of swimming in the rooftop pool at the Marina Bay Sands hotel in Singapore, as the infinity pool is 55 storeys up (665ft, 202 metres above ground)! It's three times the length of an Olympic swimming pool and also claims to be the largest outdoor pool at this height.
The newly opened Badboot (which means 'bathboat') in the Port of Antwerp, Belgium is the biggest floating swimming pool in the world and was built on a shipyard in the Netherlands before being towed over the water towards Antwerp. The pool floats on the water and is 120 metres long. It comes with a restaurant, lounge bar and a children's pool.
You'll need a real head for heights if you want to take a swim in the new pool at the Holiday Inn Shanghai Pudong Kangqiao in China. The pool, which is located on the 24th floor, extends over the side of the building and is transparent giving swimmers a stomach churning view to the ground far below. A spokesman for the hotel says: 'It needs some courage to swim to the other end.'
It may just look like a regular swimming pool at a hotel or someone's back garden but what you see is in fact the rooftop pool at Singapore's Changi International Airport. The pool overlooking the runway is the ultimate way to spend the, let's face it, tedious time waiting for your plane to leave at the airport. Just don't get too comfortable and miss your flight!
At the Jianqiao Beach Resort in northern China's Shandong Province there is a large pool filled with jelly-like beads of aloe that you can swim in before you take a dip in the sea. The reason? The resort says the jelly bath could form a protective layer on humans against ultraviolet rays and sea water irritation. We're just excited about it being a pink pool!
As far as natural swimming pools go, Cenote Dzitnup in the Yucatan, Mexico is pretty weird and awesome. To get to it visitors descend through a cramped tunnel into a massive cave where the turquoise blue pool glows under a shaft of light from a hole in the ceiling. The only catch is that the water is ice cold so you might want to swim in your thermals!
We love the Badeschiff (bathing ship) in Berlin, which is located on the Spree River and allows people to swim near the river, which is too polluted for safe bathing. The swimming pool is heated in the winter and has a roof, plus a sauna world! Who said you couldn't enjoy outdoor swimming in winter?
Ever wondered where you can find the world's biggest hotel pool? The San Alfonso Del Mar Resort in Chile is home to this gigantic swimming pool filled with 66 million gallons of salt water that stretches right across the coastline. It's not just for swimming either, as you can sail and windsurf on it too.
