Thinking about a new toilet? That's great! It's one of those home upgrades that really does make a difference, both for your daily comfort and, let's be honest, your water bill. But I've noticed a lot of folks right here in Granada Hills tend to stumble into some common traps when they're planning a toilet installation or hiring someone to do it. And believe me, you really don't want to be one of them. Let's chat about what to watch out for.
Mistake #1: Not Measuring Your Rough-In
This one's probably the biggest, and honestly, it still baffles me how often it happens. A toilet isn't just a stand-alone fixture; it has to line up with the plumbing coming out of your floor or wall. That measurement from the finished wall to the center of the drainpipe (or the bolts holding your old toilet down) — that's your 'rough-in.' Most toilets are built for a 12-inch rough-in, but you'll also find 10-inch and 14-inch versions out there. If you buy a 12-inch toilet for a 10-inch rough-in, it simply won't fit. You'll end up with a toilet you can't use, or you'll have to pay a plumber extra to move your drain line, which is a much bigger, much pricier job than just putting in a new toilet.
So, before you even start looking at styles or fancy features, grab a tape measure. Measure from the wall (not the baseboard, the actual wall surface) to the center of the bolts on your current toilet. Do it twice, just to be sure. This one simple step can save you so much grief, really.
Mistake #2: Ignoring Water Efficiency (and Rebates!)
Living here in Southern California, especially with our dry summers and the constant need to save water, you'd think everyone would be hunting for the most efficient toilet possible. But often, people just pick up whatever's on sale without checking for the WaterSense label or the Gallons Per Flush (GPF) rating. Older toilets, for example, can use anywhere from 3.5 to 5 gallons per flush, sometimes even more. Modern, high-efficiency models use just 1.28 GPF or even less.
Just imagine that difference over a year, with all those daily flushes. It really adds up! Plus, the Los Angeles Department of Water and Power (LADWP) frequently offers rebates for installing high-efficiency toilets. You could actually get money back just for making a smart choice. It's a win-win for your wallet and our local water supply, wouldn't you say?
Mistake #3: DIYing Without the Right Tools or Knowledge
Look, I totally get it. You're handy, you've watched a few YouTube videos, and a toilet installation seems pretty straightforward. And sometimes, it is! But sometimes, it's definitely not. I've been called out to homes in the Balboa Highlands area more than once where a DIY install went completely sideways because of a rusted flange, a leaky wax ring, or a stripped bolt. What started as a casual Saturday afternoon project turns into a flooded bathroom, a ruined subfloor, and an emergency plumbing call that costs way more than if you'd just hired a pro from the beginning.
You're going to need specific tools: a good wax ring (or a waxless seal, which I often prefer, to be honest), a closet spanner, a basin wrench, a level, and the know-how to seal everything properly. If you're not feeling confident, or if your existing toilet looks like it's been sitting there since the 70s, save yourself the headache. Call someone who does this kind of thing all the time.
Mistake #4: Not Checking the Contractor's Credentials
This applies to any home improvement, but especially plumbing. You're inviting someone into your home, and they're going to be working with your water and waste lines. You really want someone licensed, insured, and with a good reputation. Don't just pick the cheapest bid you find on a flyer or an online ad. Ask for their license number, then check it with the Contractors State License Board (CSLB), and absolutely ask for references. Make sure they're insured – that protects you if anything goes wrong on the job.
A good contractor, like us at Granada Hills Custom Bathrooms, will happily show you their credentials and give you a clear, written estimate. If they're vague, pushy, or demand all the cash upfront for the whole job, those are huge red flags. You're putting money into your home; make sure you're putting it into the right people.
Mistake #5: Forgetting About the Old Toilet
So, you've got your new toilet, it's installed, and it looks fantastic. Now what about the old one? It's heavy, it's awkward, and it's made of porcelain and ceramic, which can be a pain to get rid of. Some cities even have specific rules about construction debris. Don't just assume your regular trash service will take it. A professional installer will usually haul away your old toilet as part of their service. Just make sure you confirm this upfront.
Avoiding these common mistakes means your toilet installation will go smoothly, efficiently, and leave you with a reliable new fixture for many years to come. It's definitely worth taking the time to plan it right and, if you need to, bring in the pros.
