The project of reconstruction involved preservation of the existing 50-metre swimming pool and the adjoining facilities as well as demolition of the premises housing the diving pool and the heat exchanger room to allow for construction of a recreational water park and spa facilities.

As regards the swimming pool, the only structures which were kept in their original state were its foundations, load-bearing reinforced cast-in-place concrete structures with brickwork and steel columns along the eastern and southern façades, a cast-in-place concrete pool basin and steel roof trusses. A new stainless steel pool was fitted in and the building was expanded to feature a new entrance hall.

The new parts, i.e. the water park and the spa, are housed in cast-in-place reinforced concrete hall-type structures using a pile foundation system. The roof above the spa facilities is made of steel roof trusses. A common element of all three parts is the façade consisting of sandwich panels and glazed surfaces. The water park section features a whirlpool, a water slide, a torrent river, a wave pool, a diving pool and a recreational swimming pool. The swimming pools are cast-in-place reinforced concrete structures. On the first floor there is a relaxation lounge.
