How To Install A New Toilet: A Step-By-Step Guide

Is your toilet too small? Dated? Or is it always having problems? It looks like it might be time for a new one. There are plenty of reasons for swapping out a commode. Most people will avoid doing this one for themselves, but it’s definitely possible. Have you wondered how to install a new toilet? This comprehensive guide will walk you through the process step-by-step.

What You Need Before You Start

  1. A new toilet! (of course!) With so many choices out there, it can be hard to figure out which is the best option for you or your family. At Autry Plumbing, we suggest something with at least 1.6 gallons per flush—nothing less.
  2. Wax ring. This will keep the bottom of the toilet from leaking and makes a tight seal with the flange. Be sure to grab one that is extended if the flange sits below the floor.
  3. Closet bolts. These are self-adjusting bolts. You don’t have to cut any excess bolt length with these nifty things. Most stores don’t carry these, but you can find them at a plumbing supply shop.
  4. Toilet connector. These flexible steel connectors allow you to fit the supply line between the cutoff valve and the take fitting.
  5. Stainless steel washers. Use these to shim the toilet.
  6. Torpedo level
  7. Adjustable wrench
  8. Screwdriver

Assembly

We think assembling the toilet before installation is the best route. Attaching the tank adds some extra weight, but honestly, it will save you a big headache.

1.) Inspect the Flange

After getting rid of the old toilet, use a scraper or cardboard sheet to get rid of the used wax ring. Check out the flange. Is it damaged? If not, you’re good to go.

2.) Fasten the Closet Bolts

Slide the closet bolts into the parallel channels on the flange. Be sure to use the lock washers on the flange.

3.) Place Wax Ring

Put the wax ring on the flange or underneath the toilet.

4.) Set the Toilet on the Flange

Take the assembled toilet and line the holes up with the closet bolts.

5.) Add Nuts and Washers

Get all the plastic nuts and the washers to fasten the toilet. HAND-TIGHTEN. Do NOT overtighten to prevent cracking.

6.) Level the Toilet using Washers

Use the washers underneath the toilet to help level the new toilet. Plastic shims can crack and break down over time, so we suggest washers.

7.) Attach the Supply Line

The majority of toilets call for a 3/8″ connector. Opt for the ones with a rubber gasket to avoid the need for Teflon tape. 

8.) Check the Level

Once everything’s all set up, open up the supply line to allow the tank to fill up. Watch out for leaks and adjust the fill valve for the required water level.

Well, that’s all there is to it! Still a little overwhelming? No problem. Give Autry Plumbing a call! tel:8283927930 We can have that new toilet installed for you in no time and eliminate the frustration and hassle.
