Cleaning supplies vary in terms of cost. On the other hand, how much you spend on keeping your bath house dirt-free will depend on whether you do it yourself or hire a professional cleaning service. Technically, professional cleaners often estimate their cost for washing residential bathrooms at $50 to $100. Still, this cost will depend on the size of your bath space and the level of cleaning required. If you choose the DIY route, you can expect to spend anywhere from $5 to $50 on the products, depending on the brand and type of product you purchase.
