OK for 25 litre brewlengths. You would probably get a beer of about 6 to 6.5% ABV maximum (unless you add sugars) with that size, and that will be fly sparging. If you batch sparge or want to brew stronger beers, then you need to go a bit bigger. It's best to decide how you are going to sparge and what quantities you want to brew before deciding on size. If fly sparging, a decent grain bed depth of around 6-8 inches minimum is good, so the mash tun does not want to be too big. If you batch sparge, you need a bigger mash tun to hold the sparge liquor.
