Construction on the estuary pool has kicked off on the eastern foreshore, with local leaders and residents excited about the project.
The circular, enclosed estuary pool with a floating jetty platform, gives a nod back to the days of the Mandurah baths and Robert Day Memorial Pools in the 1950s and 60s.
Mandurah mayor Rhys Williams said the pool would create a space locals and tourists would love.
"The estuary pool is the centrepiece of the whole Mandurah Waterfront project - it's returning to Mandurah's heritage as the original place that people went to swim," he said.
"The waterfront redevelopment is both going to create great opportunities for local people to engage in this space they love but also a real clear indication that Mandurah's tourism experience is really lifting.
"This brings us up to a new level that's going to attract more visitors into the region - the future is really bright for Mandurah and we couldn't be more excited about that."
The construction on the pool is expected to be complete by July 2021 and has begun with the removal of the town jetty and the groyne.
The project also includes an upgraded beach area with ramp access, an upgraded jetty, and boat parking facilities to drive tourism to Mandurah.
The proposed design has got a lot of attraction online, with over 1000 people commenting on the Mandurah Mail's facebook post.
"Love it - a safe place to swim at last," one person wrote.
"This will be great for the kids and tourists," another wrote.

Mandurah MP David Templeman said the waterfront redevelopments were a "milestone moment in Mandurah's history".
"The CBD in Mandurah and the waterfront has always been the place that people remember that people gravitate to," he said.
"It is going to deliver lasting benefits in terms of investments for business, and tourism but also cement Mandurah as a key pivotal place to visit.
"If there was a cake this is the icing because what it does is it presents this part of this beautiful city to the world."
The works are a part of the overall $22 million City Centre Waterfront Project, which will revamp the eastern and western foreshores.
The Mandurah Waterfront Project includes a number of components and stages including a large-scale adventure play area, and upgrades to the Smart Street Mall.
The project is part of the City of Mandurah's bold Transform Mandurah plan - a 10-year strategy to revitalise the city centre and diversify Mandurah's economy.
