Thinking About a New Toilet? Here's the Deal.

So, you've got a toilet that's seen better days. Maybe it's constantly running, or it's just plain ugly, or maybe you're renovating a bathroom and want something fresh. A lot of folks in Owasso look at a toilet install and think, "Hey, I can do that!" And you know what? A lot of the time, you absolutely can. But there are definitely some things you need to know before you dive in, and some signs that tell you to pick up the phone and call a pro.

Before You Even Think About Unbolting That Old Bowl

First things first: the new toilet. Don't just grab the cheapest one or the prettiest one without a little thought. Toilets come in different 'rough-in' sizes – that's the distance from the wall behind the toilet to the center of the drainpipe (the bolts holding the toilet down). Most homes around here, especially in neighborhoods like Stone Canyon, have a 12-inch rough-in, but older houses might have 10-inch or even 14-inch. Measure yours accurately! If you get it wrong, your new toilet won't fit, and you'll have a big headache.

  • Measure Your Rough-In: From the wall (not the baseboard) to the center of the toilet's hold-down bolts.
  • Consider the Toilet Height: Standard height is fine, but comfort height (about 17-19 inches) is easier on the knees for a lot of people.
  • Water Efficiency: Look for WaterSense certified models. They save water, and that's good for your wallet and the environment.
  • Flushing Power: Read reviews. A toilet that clogs all the time isn't saving you any trouble.

Once you've got your new toilet picked out, make sure you have the right tools. You'll need an adjustable wrench, a screwdriver (flathead and Phillips), a utility knife, a sponge, a bucket, and some rags. You'll also need a new wax ring (get a reinforced one with a plastic horn, they're more forgiving) and new toilet bolts if your new toilet doesn't come with them.

Time to Get Your Hands Dirty: The Removal

Okay, you've got your new toilet and your tools. Now for the fun part: taking out the old one. This isn't rocket science, but it can be messy, so be prepared.

  1. Shut Off the Water: There's a small valve usually on the wall behind or to the side of the toilet. Turn it clockwise until it's tight.
  2. Flush to Empty the Tank: Hold the handle down to get as much water out of the tank as possible.
  3. Sponge Out Remaining Water: Use a sponge and a bucket to get every last drop out of the tank and bowl. You don't want dirty toilet water sloshing around your bathroom floor.
  4. Disconnect the Supply Line: Use your adjustable wrench to loosen the nut connecting the water supply line to the bottom of the toilet tank.
  5. Remove the Bolt Caps and Nuts: Pop off the decorative caps at the base of the toilet. Use your wrench to loosen and remove the nuts holding the toilet to the floor.
  6. Lift and Remove: This is where it helps to have a second person. Toilets are heavy and awkward. Lift the old toilet straight up and off the flange. Set it aside on some old towels or newspaper – it's still going to drip a bit.
  7. Clean the Flange: Scrape off the old wax ring completely. Make sure the floor flange (the pipe opening) is clean and free of debris. This is also your chance to inspect the flange. If it's cracked, corroded, or broken, that's a red flag.

Putting in the New One: The Installation

Now for the new toilet. This is where precision matters.

  1. Install New Bolts: If your flange has slots, slide the new bolts into place, making sure they're pointing straight up and are equidistant from the wall.
  2. Place the Wax Ring: This is crucial. Press the new wax ring firmly onto the bottom of the new toilet's drain opening. Don't put it on the floor flange – it's easier and more reliable on the toilet itself.
  3. Set the Toilet: Carefully lift the new toilet and align the bolt holes with the bolts sticking up from the flange. Gently lower the toilet straight down. Once it touches the wax ring, don't twist or rock it. Just press down firmly and evenly to compress the wax ring.
  4. Secure the Bolts: Hand-tighten the washers and nuts onto the bolts. Then, use your wrench to tighten them, alternating sides, a little at a time. Don't overtighten! You can crack the porcelain. Just snug them up until the toilet is stable and doesn't rock.
  5. Connect the Supply Line: Attach the water supply line to the tank inlet. Hand-tighten, then give it a quarter-turn with the wrench.
  6. Turn On the Water: Slowly open the shut-off valve. Check for leaks around the supply line connection and at the base of the toilet.
  7. Test Flush: Let the tank fill, then flush. Check for leaks again. Repeat a few times.
  8. Install the Seat: Most new toilets come with a seat, or you buy one separately. Follow the instructions to install it.

When to Call Horizons Kitchens & Bathrooms

Look, I'm all for homeowners tackling projects, but sometimes you hit a snag that's beyond a simple DIY fix. Here's when you should definitely call us or another trusted plumber:

  • Broken Flange: If that floor flange is cracked, corroded, or missing pieces, you're not just installing a toilet anymore. That's a bigger plumbing repair.
  • Leaking Pipes: If you find water damage under the old toilet, or the subfloor is soft, you've got bigger issues than just a toilet swap.
  • Toilet Rocks After Tightening: If you've tightened the bolts properly and the toilet still wobbles, you might have an uneven floor or a problem with the flange. Trying to shim it yourself can lead to cracks.
  • Water Won't Shut Off: If the shut-off valve is stuck, broken, or won't stop the water, you can't even start the job safely.
  • You Just Don't Feel Comfortable: No shame in admitting a job is over your head. It's better to call a pro than to flood your bathroom or end up with a constantly leaking toilet. We've seen plenty of DIY attempts go sideways, especially with the red clay soil we have here in Owasso sometimes causing foundation shifts that impact plumbing.

A basic toilet install is definitely doable for many homeowners. Just take your time, measure twice, and don't be afraid to ask for help if things get tricky. If you need us, give Horizons Kitchens & Bathrooms a call. We're always happy to help our neighbors out.
