Excuse the necro-thread, but I came to see if anyone had posted about bath soaps before and struck gold here.
Our shower is always full of countless bottles of herbal essences and other girly stuff, packaged in plastic and probably containing micro-plastic. I decided a few years ago to forego any plastic packaged shower products for myself and switch exclusively to bar soaps.
I dont regret it at all - it's a nicer experience all round. I am often happy with coal tar soap, but I do like to treat myself, and a big bar of good quality soap lasts quite a while thus helping to defray the initial expense.
Favourite from the past few years is probably D R Harris Sandalwood - superb quality as expected from them. Can't remember any other standouts except perhaps L'Occitane. Currently have MWF on the go and from what I can remember of the shave soap I suspect it might be exactly the same product in a different mould. Next up is Stirling Pig Trail, then I can decide what to restock with...probably something French if I haven't tried to make my own by then.
