Yes! There are both 48x48 and 32x32 versions available. :)

I don't know if you're intending to use these tiles for RPG Maker, but it does note the software for which they're designed at the top of the listing. MV uses 48x48 and VX Ace uses 32x32. It's easy to look up the graphics specs for those engines, for those who would like to use them for other engines.
