Toilets, Toilet Bowls and Repair Parts

Check the rough-in before you fall for a bowl

Start with the rough-in, the distance from the finished wall to the center of the floor drain; 12 inches is the usual figure, with 10 and 14 inch variants. Then pick round or elongated, a wall-hung model if the wall can house a carrier frame, and the flush volume. Labels such as 1.6/1.28 gpf describe dual flush: the larger figure is a full flush and the smaller a reduced one. Check whether a seat and hardware are included, since some listings say no.

Flappers and tank kits match a tank, not a shape

Most flappers come in 2 inch or 3 inch sizes, so check the flush valve opening before choosing one. Tank-to-bowl kits and tank levers are often specific to a maker, as the model numbers in titles show; a bolt kit made for one model may not seat on another. Portable toilets are different: they use a built-in waste tank instead of a drain and suit camping, boats or job sites, so compare tank volume and seat height.

Questions about Toilets, Toilet Bowls and Repair Parts

How does a dual-flush toilet work?

It has two buttons or a two-way lever. The small flush clears liquids with less water, commonly 0.8 to 1.1 gallons and up to 1.28 in some pairs, and the full flush uses up to 1.6 gallons for solids. Listings show the pair as, for example, 1.6/1.28 gpf.

What does ADA or ligature-resistant mean on a toilet?

ADA-style toilets have a taller bowl, with the seat typically 17 to 19 inches above the floor, which eases sitting and standing. Ligature-resistant models are designed without gaps or fixtures that could serve as anchor points, and are used in healthcare and secure settings.

How can I tell which tank-to-bowl kit fits my toilet?

Look for the maker's mark and model number stamped or molded inside the tank, often under the lid or on the back of the bowl. Kits are matched to that model because the gasket and bolt layout differ between tanks.
