The Tepid Baths in Auckland will officially re-open on Saturday after being closed for two years for a $15.8 million upgrade.
Mayor Len Brown will officially reopen the complex at midday and the baths will open for normal business on Sunday.
Waitemata Local Board chair Shale Chambers says it's wonderful to see the building restored to its former glory.
He says the baths are very dear to many people's hearts.
The baths opened in 1914 and the focus of the renovation has been restoring the pools and the building back to their original appearance.
The paint colour, signs, tiling and skyroof have been matched to be the same as those in the original complex.
An extra lane has been added to the main pool. A former ladies-only pool, with hanging flower baskets remains.
