What Toilet Tank Has 7-Inch Bolt Holes?

Measuring

• Measure the bolt distance of your Case toilet seat between the centers of the two holes where the seat is bolted to the toilet bowl. Modern toilets typically have a bolt distance of 5-1/2 inches, unlike older toilets that may measure 7 inches or more. Another way to measure the toilet seat is to close the lid and measure from the center of the hinge to the front of the seat. Case toilet seats were available in round or elongated sizes. Round seats measure 19 inches in length, and elongated seats are 20-3/8 inches long.

Models

• Of the 20 or so toilet models manufactured by Case, only three have seat hinges that attach to the tank on 7-inch centers. The Second Model A toilet was made between September 1935 and July 1950. The company began manufacturing the 1000 model in July 1950 and the 1150 model in October 1952.

Cost

• Parts for Case toilets tend to be on the high side compared to other toilets because original parts are hard to find. Because the company went out of business in 1963, new parts are no longer being manufactured. Seats manufactured by other companies can sometimes be used on Case toilets, but they will not fit properly. Other parts, such as ballcocks and flush valves, will only work if they were specifically made for Case toilets.

About

• Case toilets were made from vitreous china, a hard clay material that is fired at high temperatures and coated with a ceramic glaze to make it non-porous. According to their 1949 catalog, Case toilets came in a variety of colors other than white. The fittings used on the tanks were designed by the company and tailored to the individual models they were used on. All exposed metal, including the handle on the toilet, was chrome plated. According to Case, its toilets conserve water, which is an important consideration today.
