Toilet Installation
A properly installed toilet does not rock, run, or leak.
Getting it right means checking the flange, selecting the right wax ring, setting it level, and testing before leaving.
When you need a toilet installed
Replacement, upgrade, or new rough-in.
Toilet installation comes up when replacing a worn unit, upgrading to a better model, adding a bathroom in a remodel, or setting fixtures in new construction. Whatever the reason, it needs to sit level, seal completely, and flush reliably.
Wes checks the flange height and condition before any toilet goes down. A flange set too low or cracked from overtightening will cause the new installation to fail. Get it done right.
People usually call about a toilet install for one of four reasons. The old unit is cracked or has been repaired one time too many. A remodel is putting a bathroom where there was not one. Somebody in the house needs a taller seat and standard height is no longer working. Or the toilet flat out will not clear the bowl anymore, which on an early nineties low-flush is a design problem no amount of parts will solve. Each of those is a different conversation about what to buy, and Wes has that conversation before anything gets ordered.
He also asks what happens after the install. If the bathroom is getting new flooring, the toilet should come out before the floor goes down and get reset on top of it, because setting a toilet and then cutting vinyl or tile around it leaves a seam that traps water. If the vanity is being replaced the same week, sequencing the two saves a trip. This kind of scheduling is where the General Contractor side of Wes’s license earns its keep. He is thinking about the whole room, not only the fixture in front of him.

The flange determines how long the install lasts
Check it before anything goes down.
The toilet flange is the fitting in the floor the toilet bolts to. A flange at the wrong height, cracked, or corroded will cause the new wax ring to fail early. Wes inspects and repairs the flange before installation as part of doing the job right, not as an upsell.
Flange height is the number that decides which wax ring goes down. The flange is supposed to sit on top of the finished floor. When somebody tiles a bathroom without raising the flange, it ends up sitting a half inch or more below the tile, and a standard wax ring cannot bridge that gap reliably. The wrong answer is stacking two rings, which is a trick that holds for a season and then slumps. The right answer is a flange extender ring set on the existing flange and sealed, so the toilet lands on a proper surface. That is a fifteen minute difference on install day and years of difference afterward.
Flange material matters too. A lot of older Littleton homes have cast iron flanges caulked into cast iron closet bends, and those corrode at the bolt slots until the ears break clean off. Newer homes have PVC flanges, which crack instead of rust, usually because the last person torqued the closet bolts down like lug nuts. Both are fixable. Cast iron takes a repair ring or a replacement flange; PVC usually takes a stainless repair ring screwed into solid subfloor. What is not fixable is bolting a new toilet to a flange that has nothing left to grab.
After the toilet is set, he adjusts the fill valve for correct tank level, tests multiple flushes, and checks for any supply line seepage before calling it done. He also runs a bead of caulk around the base, leaving the back open. That is deliberate. Caulking the base keeps mop water and mess out from underneath, and the open gap at the back means a leak has somewhere to show itself instead of quietly soaking the subfloor.

Models and rough-in sizing
The replacement has to fit.
Most homes have a 12-inch rough-in. Some older homes have 10 or 14-inch rough-ins that limit choices. Wes measures before recommending a model. He advises on height, flush performance, and water usage without steering toward the most expensive option. See our work.
Rough-in is measured from the finished wall behind the toilet to the center of the closet bolts, not to the edge of the baseboard. That distinction throws people off by three quarters of an inch and sends them home with the wrong unit. Twelve inches covers most of what got built in the metro after about 1970. Ten-inch rough-ins turn up in older Englewood and Denver bungalows and in half baths that were squeezed into tight spots. Fourteen shows up occasionally in custom work. Ten and fourteen inch models exist, but the selection is thinner and they are rarely in stock locally, so knowing the number early keeps the project from stalling.
Then there is bowl shape and height. Elongated bowls are more comfortable and take about two more inches of floor space, which is exactly what a cramped powder room does not have. Comfort height sits closer to a chair and is easier on knees and hips, which is why it is the default request from anyone planning to age in the house. Standard height is still better for households with small kids. There is no universally correct answer, only the right one for the people using that bathroom, and Wes asks rather than assumes. If the whole room is changing, bathroom plumbing remodeling is the broader scope, and toilet repair covers the case where the unit you have is worth saving.
Tested before leaving
Toilet installation done right.
Every step: checking the flange, right wax ring, level set, even bolt torque, fill valve adjustment, multiple flush test. Wes does all of it. You get a working toilet before he leaves the house.
Level is not cosmetic. A toilet that rocks even slightly is working the wax seal a little with every use, and a wax seal that gets worked eventually stops sealing. Old bathroom floors are rarely flat, especially in houses that have settled or had layers of flooring added over decades. The fix is shims under the low side, trimmed flush and hidden in the caulk line, with the closet bolts brought down evenly rather than cranked. Uneven torque is how china cracks, and a hairline crack in a toilet base is not a repair, it is a new toilet.
The old unit leaves with him, and the new supply line goes on with a proper braided connector rather than whatever chrome tube was there before. If your toilet quit on a Sunday night, that is not a reason to wait. Wes takes calls 24 hours a day, seven days a week, out of Littleton and across the Denver metro and Front Range.

Questions about toilet installation.
Can you install a toilet I already purchased?
Yes. We inspect the flange first and let you know if anything needs addressing before the toilet goes down. Bring the box unopened if you can, because if the rough-in turns out to be ten or fourteen inches instead of twelve, an unopened box goes back to the store without an argument. Measure from the finished wall to the closet bolts and you will already know.
How long does installation take?
A straightforward replacement is one to two hours. Flange repair adds an hour, sometimes more if the subfloor around it has gone soft and needs to be cut out and rebuilt. New construction sets go faster because the floor is open and nothing has to be worked around. Wes gives you the likely window once he has looked at the flange.
What is comfort height?
Roughly 17 to 19 inches from floor to the top of the seat, against about 15 on a standard bowl. It lands closer to the height of a dining chair, which is easier on knees, hips, and backs. It is the usual pick for anyone planning to stay in the house a long time. Households with young children often prefer standard height for exactly the opposite reason.
Do you install bidet seats?
Yes. Bidet seats need a nearby GFCI outlet and a tee off the toilet supply, which is straightforward on most installs. The thing to check first is bowl shape and mounting hole spacing, since a seat sized for an elongated bowl will overhang a round one. Wes confirms fit and adds the outlet if there is not one within reach.
Do I need a permit to install a toilet?
Replacing a toilet in the same spot does not require one. Adding a toilet where there was not one before does, because that means new drain, vent, and supply work that has to be inspected. Basement bathrooms and bathroom additions fall in that category. Wes holds a Master Plumber license and a General Contractor license and handles the permit and inspection process on those jobs.
Can a toilet be installed in a basement below the sewer line?
Yes, but not with a standard gravity toilet. Below the main drain you need either an up-flush macerating system or a sewage ejector pit cut into the slab with a pump. Ejector pits are the more permanent answer and are what Wes usually recommends for a basement bath that will get regular use. Both need proper venting to work right.
What should I do with the old toilet?
Wes hauls it off. The old unit gets disconnected, drained, and taken out of the house as part of the job, so you are not left with a used toilet sitting in the garage waiting for a trip to the transfer station. Some Colorado water districts run rebate programs when an old high-volume toilet is swapped for a WaterSense model, and he will point you at those if they apply.
Will the new toilet flush as well as my old one?
A good modern 1.28 gallon unit generally clears better than a 3.5 gallon tank from the eighties. The gain came from redesigning the bowl and widening the trapway, not from adding water. The reputation for weak flushing traces back to the first wave of 1.6 gallon models in the nineties, which genuinely did not work. Wes will steer you toward the ones he has installed and not been called back about.
Need a toilet installed?
Wes sets it level, seals it right, tests it before he leaves.
