Do Brazil passport holders need a visa to visit BS?

No visa needed. Brazilian ordinary passport holders can enter The Bahamas visa-free for tourism for up to 3 months (extendable on the islands). You just need a valid passport, proof of onward travel, accommodation details, and a yellow fever vaccination certificate (because you are arriving from Brazil). Brazil appears on the official Bahamas Ministry of Foreign Affairs list of countries whose nationals do NOT require a visa to enter The Bahamas. A Brazilian ordinary passport holder may travel for tourism and short visits without applying for any visa in advance. The standard visa-free stay is up to 3 months, and the Bahamas Immigration Department allows visitors to apply on-island for an extension up to a maximum of 8 months in total, provided they can support themselves and do not engage in any gainful employment. On arrival, travelers must present a passport valid for at least six months, a return or onward ticket, evidence of sufficient funds (or a local sponsor), and accommodation details. Critically, because flights originate from Brazil (a yellow fever risk country), travelers aged one year and older must carry an International Certificate of Vaccination against yellow fever. The Bahamas is in the Caribbean and is NOT part of the Schengen area, so no Schengen 90/180 rule or ETIAS applies. There is no eVisa, ETA, or arrival-fee scheme for visa-exempt tourists; the only routine cost is the departure tax, which is normally bundled into the airline ticket price.
