Different materials had been used for sink fabrication in recent years. In this study ceramic filled polyester composite material has been developed by adding micro-fine limestone and clay ceramic particulates with particle size of <134 μm to unsaturated polyester resin with a loading weight of 20% limestone and 30% limestone/clay and fixed amount of catalyst (1% weight). The reaction temperature lies within 95.8 – 150 oC. Resin Transfer Molding (RTM) technique has been used to fabricate a prototype sink using wooden and Plaster of Paris (POP) mold with a view to examine surface finish. The prototype sink produced shows durability with smooth surface finish and can be customized to satisfy end user's preference and choice.
