A wall-mounted toilet is a type of toilet that is attached to the wall, rather than the floor. It is a great option for small bathrooms as it frees up floor space, making the room look bigger. Wall-mounted toilets are also popular in modern and contemporary designs, as they offer a sleek and minimalist look. Installing a wall-mounted toilet typically requires professional assistance, as it involves cutting a hole in the wall for the waste pipe and ensuring proper support for the weight of the toilet. However, the benefits of a wall-mounted toilet make it a worthwhile investment for many homeowners.
