The goal of measuring for toilet installation is to avoid placing the toilet in a space that is already crammed with a bathtub and vanity. Follow these tips to prevent issues.
Choosing the Right Seat
Decide which size toilet you will install before you make your measurements. The standard size is bigger than older models, but you can still get a toilet with old dimensions by custom ordering it. These old units are now called cottage toilets, and they are perfect for houses with small comfort rooms. If your toilet space is very tight, try using a high tank toilet instead.
To take a proper measurement for your toilet seat, go from one sidewall to another in order to allow enough elbow room. If you are in a room with an angled corner, ensure that the fattest portion of the seat is located within 30 inches of the space. This measurement should be followed even if it means the tank area will be tight.
When you are measuring the area for the front portion of the toilet, bear in mind that the code mandates it to be at least 24-inches. If your space is very limited, make sure that your toilet is not elongated. An elongated toilet would measure 17-inches instead of the standard 15-inches.
Replacing an Old Toilet
If you will be installing a new toilet in place of an old unit, take your measurement by going from the center mounting bolt at the back to the toilet back. Take note of this measurement and compare it with the measurement for the new toilet. If your measurement is smaller or equal to the old unit, you will not have a problem with the already existing drain pipe as the new seat would fit right in.
Toilet for Young Children
If you have kids around the house, you can install a shorter toilet instead. This type of bowl measures 14-inches to the top of the toilet. Take your toilet height measurement by going from the base of the toilet seat to the topmost part of the seat. On the other hand, older people that already suffer from weak knees will need a higher seat, which measures 17-inches. If you have floor joists, you can accommodate them with a specially sized toilet.
