Started a major remodel several months ago and, given the uncertainty of the supply chain, ordered as much as I could in advance. One item, from QS supplies was a 800 x 1700 shower pan. Imagine my surprise (and my neighbors) when it was delivered at 4:30 AM! That was just the beginning. I stored the shower pan flat, as recommended, and when I went to install it, 2 months later, it was quite the banana. First QS Supplies said I had installed in incorrectly and when I explained that it hadn't been installed (only an idiot would install something this bent) they said I must have stored it improperly. Bottom line - they have good prices, but who delivers at 4:30 AM - the same people who will sell you defective product and then blame you for it. Avoid at all costs.
