We can accommodate some customer-supplied products by prior agreement, but generally prefer to supply the majority of products. This helps us check compatibility, coordinate deliveries and provide aftercare. Customer-supplied products are not covered by our product warranty, and labour to remove or refit a faulty customer-supplied product is not covered.
Let’s say you buy a concealed shower that fails. Although the place you bought the item from might give you a replacement, you’ll still have to pay for the replacement labour (which is usually more than the cost of the item). In the shower case, if we would have supplied it, then all the liability to replace would be on us.
