The standard width is 5½ inches, but it can vary depending on the model. - Next, measure the width of the seat at its widest point. - Finally, measure the length of the seat at its longest point (from the center point between the two bolts to the outermost lip). If you have a standard toilet, a round bowl should have a length of 16½ inches, while elongated bowls will be about 18 inches. A compact elongated seat will fall somewhere in the middle. Once you have the measurements, you can shop for the right size seat. ## Step 2: Choose a new toilet seat. ![Toilet seat half open]() *Photo: Jenny Stanley* If you are planning to replace a toilet seat, especially if it’s been some time since you last researched them, keep an eye out for these key features: **Quiet closing**: Gone are the days of toilet seats banging closed. You can now select a product with hinges designed to let the seat down gently. Consider the [Kohler K-20110-0 Brevia Elongated Toilet Seat](). **Molded bumpers**: The simple, no-nonsense advantages of molded-in-place bumpers? They prevent the seat from damaging the toilet, add stability to the seat, and reduce noise when closing the toilet lid. [Kohler’s 20111-0 Brevia Round Toilet Seat]() is a good choice. **Colors**: Toilet seats now come in dozens of colors. One manufacturer, Bemis, offers a [color selector tool]() to help homeowners navigate the field of available options. **Cleaning**: The better the seat, the easier it is to remove for cleaning. Look for a model that can be taken off with nothing more than a [screwdriver](). There are also quick-release seats that allow for easy, tool-free removal so you can clean the seat and the area around the hinges. **Durability**: Choose a toilet seat with stainless steel or zinc-plated hinge posts, which will neither snap nor corrode as they hold the toilet seat in place. For the seat itself, although wood is more comfortable, plastic is more common because it’s easier to clean and more durable. **Versatility**: For kids, there are “trainer” models that have built-in removable potty seats. The Mayfair 1888SLOW 000 NextStep2 is a good option. For senior citizens and others who might need assistance sitting and standing, consider a toilet seat that features side arms with slip-resistant grips, such as the [RMS Raised Toilet Seat](). **Comfort**: If you cringe at the thought of sitting on an ice-cold toilet seat in the wintertime, consider upgrading to a heated model like the [TOTO Heated Seat](), named in our list of the best [heated toilet seats](). ## Step 3: Remove your old toilet seat. ![Person screwing in toilet seat]() *Photo: Jenny Stanley for BobVila.com* Removing an old toilet seat is a simple, though occasionally physically awkward, matter. Here’s how to go about it: - Pop open the plastic flaps covering the bolts. A screwdriver may help. - Check to see if the hinges have corroded. - If so, spray each nut with penetrating oil and wait 10 minutes. - Hold the bolt in place with an [adjustable wrench]() while loosening the nut below it with a socket wrench with a deep well [socket]() that can cover the long bolt while still reaching the nut. (Note: These days, many toilet seat hinge bolts can be removed by holding the nut in place with your fingers and unscrewing the bolt with a large slotted screwdriver.) You may find that the threads on the bolt are so heavily corroded that no amount of penetrating oil will work. If so, you’ll need to use a drill to bore a hole into the bolt. Begin with a 1/16-inch bit and follow up with progressively larger bits. (Be sure to wear safety goggles.) Next, grab your socket wrench or adjustable wrench and twist the nut until the bolt snaps off. Use this method at your own risk because applying too much lateral force to the bolt can potentially crack the bowl. **PRO TIP** "I replaced my toilet seat because my old one cracked when the heavy lid slammed down on it a few too many times. Installing a new soft-close model was beyond easy—I unscrewed the old one and screwed on the new one—and the improvement exceeded my expectations. No more slamming lid and no more cracked seat for the foreseeable future." *—Jenny Stanley, Executive Editor, Service & News, Bob Vila* ## Step 4: Install the new toilet seat. ![how to replace a toilet seat]() *Photo: istockphoto.com* The good news is that today's toilet seats are so easy to install that removing the old one is the hardest part. **Note**: Different toilet seats may require slightly different installation methods. Consult the manufacturer's instructions for exact steps. Few tools are required to [install a toilet seat](); more often than not it’s a simple matter screwing and unscrewing some nuts and bolts. First, slide the bolts through the appropriate holes in the bowl. Then, using an [adjustable wrench](), tighten the nut situated beneath the mounting deck. The larger or more elongated the nut, the easier your job is going to be. (Again, note that newer toilet seats can often be installed with a large screwdriver and tightened by hand.). Some toilet seat replacement kits may require the use of a tool specially designed for tight spaces. ## FAQs ## Author Joe Provey is an expert on all things home and garden.
