There are thousands of markets in Bangkok.  Fruit markets, wet markets, night markets, etc.  But when people talk about “The” market, they are talking about Chatuchak.  The Chatuchak market has been open for almost 80 years, and is the largest and most diverse weekend market in the world, with over 15000 stalls.  It averages over 200 thousand visitors every weekend.  If you need it, chances are you can buy it at the market.
