Household dryers have these things inside that are resistive, called elements, have been around a while. Typically are around 8-12 ohms, rated at over 5000 watts, might be worth a try since they are going to cost less than $50 for a pair of them if you look around.
Anyone can find a large resistor if you pay enough, nothing special there.
And industrial water cooled resistors have been around for a while too…

Wire wound resistors , or whatever type, can take a lot more in rush current and general abuse than the metal film power type. Looking at the data sheets the WW can take 10x rated briefly whereas the number for the packaged types above is something like twice rated for the same period.
It means that unless you need full power, long duration testing, you can get away with smaller and cheaper resistors and something like a bucket of water for high power tests.
