Baptism is a Holy Sacrament by which we are born again by being immersed in water three times in the name of the Holy Trinity; the Father, the Son and the Holy Spirit.
The Sacrament of Baptism has the first rank among the Seven Holy Sacraments, as it is the door by which the believer enters the church and has the right to partake in the rest of the Sacraments.
It is usually to be located on the western southern side of the Nave. It may also be designed in a completely different location near the church.
Having a source of water with hot and cold water and proper sewer system is a must. Immersing adults in a baptistry requires a special design one similar to the pictures below.
