There are many things to consider when buying toilets, so to help you make the right decisions we offer a number of great tips, touching on aspects such as bowl size and flushing systems.
The dimensions of toilets are vital to get right as every bathroom is unique in its space constraints. The first thing to determine is the rough-in size, which is the distance between the wall and the outlet pipe. Doing so will tell you what size toilet is right for your bathroom, with the standard being 12 inches. If the space either side of the toilet is a constraint, you might also want to check the distance between the flange bolts and the side walls.
Bowl Shape & Height
The toilet bowl can come in round and oval shapes to suit your preferences. With elongated bowls, you get an extra two inches of length for added comfort, but these are usually more costly. In terms of space, round toilets suit smaller bathrooms. Another thing to consider is the bowl height, which is usually between 14 and 15 inches. Those with difficulty getting up and down may want to choose a bowl with a higher reach.
The style of toilets can be described as one-piece or two-piece. By two-piece, it is meant that the bowl and cistern are connected by piping, while a one-piece tank is connected directly to the tank. One-piece models are easier to clean, but two-piece(close coupled) varieties are cheaper. As well as the actual toilet, the way toilets are fitted is an option to decide on. These days, more and more people are choosing to mount their toilets to walls, but this requires plumbing modifications.
The cistern is the part of the toilet that holds the water and flushes the waste down the toilet. The amount of water it holds is called the cistern capacity, and when choosing your cistern, considerations such as level placement and size of the valve (which determines the flushing speed) will be things to consider.
The inlet pipes feed water into the cistern and waste pipes direct waste away from the bowl to the sewers below. In terms of water flow, there are two types of flush systems: gravity and pressure-assisted. Gravity-assisted is simpler and quieter. You also have a choice of single and dual flushers, the latter of which allows you to flush away water waste using only 50% of the tank.
