Recently, I almost bought a shower panel from Amazon, that required two separate water connections, one for the normal water and the other for hot water. But our bathroom has only one nozzle, the water connections were inside the drywall. I only got the information as I have a habit of reading a few bad reviews (1/2 star rated reviews) of a product before buying it.
Had I gotten that I’d have spent $300, after reading the reviews, I bought a $40 shower head instead. The internet not only allows you to find products fast and conveniently but also to save money when you are shopping. With a little bit of internet research, you can spend less than usual on your shopping.
