Question: Why is it essential to install a water-efficient toilet?
Answer: Installing a water-efficient toilet helps you to save water. Water-efficient toilets use less than 1.28 GPF. This means you will also get a lower water bill in the end. In some states, you may get rebates when you install a high-efficiency toilet.

With a much-improved technology, using less water to eliminate waste doesn’t mean that the toilet user will have to flush several times. Low-flow toilets still perform at a high level using less water than old toilets. Most of them feature very efficient flushing systems that clear waste and leave the bowl clean.

Question: Which one is better – elongated or round bowl?
Answer: It depends on your needs. However, elongated front bowl toilets offer greater comfort when compared to round front bowl toilets. This is because they provide additional sitting space, which can comfortably accommodate even plus-size people. On the other hand, round bowl toilets are usually compact and not comfortable for all people. Nevertheless, their compact design makes them suitable for small bathrooms as they are slightly smaller than their elongated counterpart.
