It depends on the faucet you select. While some faucets produce only cold water, the majority give you both options. To access hot water, the sink must be linked to your home’s existing water lines to pull from the water heater. Otherwise, you’d need to use a dedicated water heater. Small water heaters (about 10 gallons at most) are available for less than 0, while point-of-use mini-tanks run a bit cheaper. Just keep in mind that dedicated water heaters must be drained if used outdoors during the winter. Hot water in an outdoor kitchen is something of luxury, but it’ll make washing dishes much easier and more hygienic.
